Were you smuggling peanuts! :boxedin:
Walnuts and a Chippolta!
looking good Stu hope to see you about this year
Well after weeks waiting for email responses etc regards getting my camshaft machined I decided to get it done by a local place after finding
out the required dimensions. 4 Days later and shes all done
so todays daunting task was marking and drilling/tapping for the two bolts to hold the retaining plate on.
I put some masking tape around the cam to make the plate a snug fit/keep it central. Then use a transfer punch through the holes to mark the block. The holes
dont need to be very deep approx 3/4".
After much nervousness and sweating got both holes drilled tapped, and didnt break into any oilways :boxedin:
I had already measured the machining work beforehand, but a quick check with the DTI showed just under 0.005" end float on the cam, spot on! :headbang:: (should be 0.003 to 0.005")
With this done i can FINALLY start putting this engine back together, hopefully this weekend :guitar3:
Sometimes it's hard to give the patience needed for a job. Obviously it was the thing to do here - - the only way to the right result. :thumbup1:
Gissashout if you need a hand.
Couple of afternoons in the garage and we are starting to get somewhere :thumbup1:
Engine pretty much all buttoned back up again, lifter preload all reset. Just needs plumbing and exhaust etc putting back on. Hoping that new headgaskets have stopped the oil weeping down the sides of the block!
Also completed the rollcage install. Mr Finn helped me out last week getting the reinforcing plates welded in, and I got it in and bolted up today :guitar3:
Waiting on some brake line and a few gaskets but on track for having her all back together for the end of march.
Brilliant! Soon be burning some rubber. Finn.
glad its getting there Stu!
Nice one Stu, looking good :thumbup1:
Great work Stu, looking forward to seeing it done
Engine is looking good Stu..
enjoy looking at your work ..
what Manifold is that, I used the Edelbrock dual plane for mine ..
I am using an Edelbrock 500 4barrel on mine, what you going for ??
Manifold is a Single Plane Willpower Manifold (originates from Australia, I got this from a guy in Norway lolol) You do loose a bit of low end grunt
but makes up for it with flow at higher rpms
Also running a Edelbrock 500 on this, got about 180 miles on the engine last year and almost had it dialed in, just gotta lean out WOT a bit more :guitar3:
At last I have had time to work on the beast again! (5 weeks of being ridiculously busy at work as well as putting in a new kitchen at home!)
Got a lot of work done over the past 2/3 days.
Exhaust is back on
Changed out the stainless braided brake lines for Kunifer where possible (wasnt happy with the pedal feel)
Started getting everything in the engine bay bolted back in and hooked up
Got the sealed+vented aluminium battery box fitted (just need to trim the mounting studs)
Swapped back to a mechanical fuel pressure gauge mounted to the regulator, which allowed me to fit a second AFR gauge in the dash so I can now keep an eye on both banks :guitar3:/>/>/>/>
Started running the fuel lines under the car, just waiting on some more p-clips)
Engine is pretty much back together, and this time I shall get the cold air intakes hooked up properly :thumbup1:/>/>/>/> Also did an oil and filter change, filled her up with some proper oil :headbang::/>/>/>/>
Still got quite a bit to do:
Refit radiator with new fans
Finish fuel lines
Fit new seatbelts
Modify seat mouting brackets and refit
Water pump gasket
plus a few other odd jobs.
With a bit of luck I shall be taking it for a drive next sunday :banana:/>/>/>/>
Come via Manea and pick me up? Finn.
nice one Stu, nearly there mate can't wait to see that m.o.t
Already got the MOT Trev />/>/>/>/>/> , just didnt drive it very much last year before I pulled it apart again! :boxedin:/>/>/>/>/>/> lolol/>/>/>/>/>/>
Whilst under the car the other day I noticed that the gearbox mount seemed to be quite low in the crossmember, a closer look found that the gearbox case
was actually resting on it!. I don't know if this was just a bad replacement rubber or the wrong one entirely but it needed sorting. :sleepy:/>/>/>/>/>/>
Bit of research later and I found an aftermarket mount intended for a sierra with a T5 box, but with the same bolt spacing and made to accept the "wedge" found on most of the ford/capri gearboxes (type 9, type 5 etc)
Little bit of fettling on the crossmember and it bolted right up. I fitted it to the underside of the crossmember as per the normal rubber mount and that puts the height about where it should be.
Back on the car and jobs a goodun, gearbox now clear of crossmember and nice and solid. :guitar3:/>/>/>/>/>/>
Excellent work as always. Paul.
So after another few days work shes pretty much done :guitar3:
New spal fans fitted to the radiator and whole lot back in the car
Finished installing and wiring the second AFR gauge so I can keep an eye on both banks :thumbup1:
Interior Back in, and Safety first - fitted a 1.75L extinguisher
All buttoned up and back on her wheels.
I didnt get round to taking it for a drive, but have had the engine running again and after a little mishap with the timing (it was only 26 degrees out! lolol ) its running
bob on. Having the dual widebands is great as it showed that at idle the mixture was rich on the drivers side bank so adjusted that to get them both spot on :guitar3:
If the weather holds out shall hopefully take it to work a couple of days this week (neighbours will love that at 6.30am lolol )
Looks like a real mean beast that Stu! Look forward to seeing that at some events
nice one Stu, great to see it finished, make sure your neighbours hear you leave
Cheers for the comments all.
Final piece to the puzzle done this evening. Never got round to completing it last year, but finally got the cold air intake in the headlamps routed
to the engine :guitar3:
Now to drive the bloody thing :boxedin:
The Beast has risen!
Those hamsters live in a mean-looking neighbourhood ! :thumbup1: :thumbup1: Finishing that should give you some strange free time and boost your budget. Live it up, at speed. :banana:
Had a ride in the beast around the village, GREAT! Finn.
nice one Stu, great to see it done, now enjoy!!
Been a little while since I Updated.
I decided to finish the exhaust properly, and routed it up over the axle and out the back of the car. (originally it dumped just before the axle). Sounds a lot better and little less resonance inside :thumbup1:
After much faffing with the carburetor, I just couldn't quite get it to run without compromising somewhere, be it the mixture whilst cruising, or it being too lean/rich at WOT.
So I opted to go with fuel injection :guitar3:
Been looking at these type of kits for a while, and decided to go with the Holley Terminator EFI setup, which uses a 4 barrel throttle body with 4 injectors.
Easy to wire in, comes with a ready made loom which is plug and play except for 4 loose wires to connect
The only modification I have had to make is downsizing from 80lb injectors to 60lb due to currently only running the 3.5L
After setting it all up with the handheld it fired first try (if a little rich), and having put about 200 miles on it now, allowing the ECU to "learn" its running better than it ever has :headbang::
This will also make future upgrades easier, maybe a little bit of boost? h34r:
Tried one run up the strip at the Classic Ford show, unfortunately it fell flat on its face off the line, eventually got going and did a 15.8 but at 95mph lolol/>
The acceleration fuelling has to be tuned manually and it was way to rich and flooded the engine. Have now tweaked this and shall be trying again next saturday, see if I can get a better time :lol:
OK Stuball, the time has come! The Beast From The East V A666, A141, Mepal straight, 06.00, see you there.We will need a starter, one of those scantily clad young ladies with a flag! Paul.
Just a little update with whats been going on with the beast lately
Done a few runs at santa pod over the past couple of weeks.
15.8 @ 95mph - Unfortunately the EFI tune was off and it went way rich off the line and bogged
14.7 @ 91mph - A bit of a tune up sorted the bog, gentle 2000rpm launch, purposely slipped the clutch (didnt want to break anything!), minor tire spin
15.9 @ 88mph - 2500rpm launch, dropped the clutch and span 1 tyre through the 60ft, had to peddle it a bit then short shifted by accident :boxedin:
I think the next step with this is some changes to the rear axle. It definitely needs an LSD for better traction (and so that I can actually warm up BOTH tyres before a run! lolol ). Also looking
to change from the 3.09 gears to 3.44 as at the top end of the track engine is a bit flat so the shorter gears should pep it up a bit :lol:
Blimey, been a long time since i updated this!!
Didn't get up to too much with the car over July/August, mostly driving it!
The EFI tune is getting pretty good now, still need to work on cold start and idle to get a few little bugs out of the system but its going well
As I am running a Holley ECU setup I decided to indulge and upgrade my dashboard.
This is the touchscreen digital dash that they do. Plugs right into the ECU. It can also accept other inputs so I have added fuel level, speed (GPS sensor), and also left/right indicator, handbrake and high beam warning lights. Makes for a much cleaner looking dashboard
During a rather "spirited" drive, I have found that at high rpm the rpm signal from the coil seems to get quite erratic, resulting in loud pops and bangs from the exhaust as the ECU gets all confused . This is despite using a shielded signal wire/routing it away from anything that might interfere.
This made me decide to bring forward a planned future upgrade and switch to coil packs/wasted spark ignition. Current system is already setup to take 8 individual coils (like an LS engine), and is very much plug and play, I just needed to sort a few other bits first.
Removing the distributor meant I needed to blank the hole, so whipped this up at work.
I also needed a trigger wheel and crank sensor/bracket. (courtesy of Emerald)
Opted to run LS style coil packs with brackets to fit them to the rocker covers.
Hoping to get them all wired over the weekend.
Looking good Stu!
Did you get them all wired up?
nice one Stu!
Didn't quite get finished over the weekend. Had to order a new crimping tool for the ecu terminals so waiting on that now.
Looking good mate, be good to see it again in a few weeks
It looks amazing. Very interested to see how you get on with the self learning compact fuel injection. They are getting to be a very popular upgrade in the US now on all manner of classics as they improve power, economy and reliability but can still look fairly original.
Does this control the ignition too or have you used a separate distributorless ignition setup such as a Megajolt or No-dis ?
One reason I went for the more expensive Holley "Terminator" kit, is the ECU is identical to there "HP" ecu (rather than being built into the throttle body), So once you update the firmware it is fully programmable using a laptop. I started with just using a normal distributor and coil for the ignition (using the coil for the Rpm signal), but the ECU has the connections to run crank sensor and coil packs. which is the upgrade I am doing at the moment. So will be able to fully control the ignition too.
HT leads made up tonight
Woops!, 7 months without an update...........................
Anyway, Over the winter have been doing a few jobs on the capri. It is also now running on coil packs quite happily
First major job was a radiator upgrade. It was ok last year but only just.....
Ordered one from the states that pretty much fills the front end of the car! (this will also cover me for future power increases)
I have also upgraded the rear axle. Had a spare one rebuilt with a Quaife ATB differential and 3.64 gears. Finally fitted today.
Shes now all cleaned up and ready for the first drive of the year
Cool. I was going to ask for an update the other day but forgot in the end.
I like the radiator, mine is an alloy one but I'm worried that it'll be to small as it's not as long as yours. Where'd you get it, summit racing ?
It's a shame your old post photos don't work as I look at your build a fair bit.
Yeah go it from summit racing. Id have to check but I belive it was 26x16 inches altogether.
If I ever get enough spare time I shall try to repair all the images, I did save them from "that photo website that shall not be named" thankfully.
Good to see an update Stu, looking great. When is first drive then?
So, Had the first drive out today, its a whole new car!!! Changing from 3.09 to 3.64 gears, massive difference!!! So much more fun to drive now
Got 50 miles on the new gears taking it easy, just gotta change out the diff oil and should be good to go
It was quick already so gonna be good now!
good to see you got there with it stu might see you at some meets once im sorted
Been tinkering this week. Needed to fit a cam position sensor so I could switch from firing the coil-packs in pairs to firing individual cylinders.
Bought an old distributor, trimmed it down and made a cap for it to mount the sensor
Removed all the internal gubbins and drilled/tapped the rotor
Flying magnet target fiteed and sensor installed
Cranked engine over and laptop was showing that all is working as it should, result!
However, I am still chasing down a high rpm misfire, which looking at this log seems to be caused by a loss of both crank AND cam signals.
They share a common power source so will look into this first.
Good work stu, I wish you'd said about the dizzy as I've got one you could of had for nowt.
nice bit of kit Stu
Been some time since I last posted an update!
Towards the end of the show season last year I was STILL chasing this misfire down, and it was starting to occur at lower and lower rpm (initially 5800, then 5600, 5400 etc etc). Having exhausted anything electrical and fueling wise I bit the bullet and pulled the engine apart.
Unfortunately the camshaft/lifters had not bedded in properly and were eating each other!!
So took this opportunity to go for a more loopy camshaft, this time with solid lifters to avoid faffing with preload. However due to the extra lift I did have to redo the valve reliefs in the pistons, fun times!
It was around November now and finally got the engine running again, sounds even more angry than before
Of course these project cars are never finished, and despite just fitting a new camshaft and not yet taking it for a test drive, a good (or would that be bad?) friend offered me his old supercharger, I couldnt say no!!
So the adding of boost is currently in progress, watch this space!
Lol let's hope nobody offers you nos or anything else!
Great update Stu. A few questions.
Where did you get the water pump from ? I've used a Davis Craig pump as I didn't think there was one available for the rover like you've got.
Nice blower ! What compression ratio is the engine running ? How much boost are you thinking of running ?
Water pump is from Summit Racing, its made by Meziere (you have to look up the Buick V8, 3.5L), brace your wallet though!, and bear in mind it only fits the early timing covers, not the later serp ones with the reverse rotation water pump
Compression ratio is about 9-9.5:1 at the mo with the cam overlap.
Wont be running much more than 7-8psi (maybe 10-11 if I fit water/meth injection) due to stock cast pistons, but will still give a healthy power gain
nice bit of work Stu looks a bit like the set up Tony cooper is running, think he just up graded his charger and at present he`s fitting abs as well
Nice choice of cam Stu, whats the difference in the torque curve ?
Funny you should mention Tony, this is his old charger
Not sure on the power difference with the cam yet, never had the car dynod, but the spec of the cam has pushed the power band up the rev range by a good chunk, which works for me as the car is quite light and the engine revs VERY quick with the 3.64 gears in the rear axle
Bit more done this week. Mocked up the boost hoses. As i'm only running around 7-8psi I have forgone an intercooler for now but if necessary I shall fit water/meth injection as it is a nice neat solution (plus being a centrifugal charger it will only make that sort of boost at high rpm). The bonnet does need a bit of a fettle to clear the hose though!
And first belt i've tried fits well, though near the limit of the alternator adjuster so need a slightly shorter one. I know having an auto tensioner would be ideal, but difficult to make one fit with the non-serp front timing cover. I wont be running the charger particularly hard so I will wait and see if belt slip is an issue.
Lookin good Stu! This race is getting closer lol!
awesome update ! love the blower.
haha i knew he had sold it whats the chance it would be you haha
ive now sold my 8 pot for a good profit but my look out for another yet
A PK1650 looks to be needed, l have just been struggling with a PK1750 on a secret project, but l am using an auto tensioner.
Turns out I actually need a 1750....... I did all the measuring but forgot that I still had the small pulley fitted to the charger. Now I've fitted the bigger pulley its all wrong lol
I'm showing my age, but these belts at one time cost £3.99. That's inflation!!! Got loads of old stock ordinary v belts, but nothing is fitted with them now and as with anything NOS would l really trust them!!
Nearly there with the engine now.
Remounted the radiator fan off to one side so it would clear the electric water pump, it fits, just
Oil cooler for the supercharger mounted
Also sorted out inlet pipework and air filter, theres a Rover V8 under all that somewhere
Not much left to do now, couple of oil hoses to fit, lower rad hose to finish and new catch can when it arrives. Hoping to fire it up next weekend once I have done the new fuel map for it Then just need to fettle the bonnet so that it clears the boost pipes
Looking nice in there Stu good work mate
Wont you be picking up heat from the rear of the bay like that
to begin with yes, but I am planning on fitting a cowl induction scoop to the bonnet, and shall box in the filter to pull air from the outside once that is done
any up dates stu, i dont get on as much due to work and private engine builds i have going on, but when i do get on i look to see what your upto
Been a while since the last update.
Final modifications were complete this week, installed a cosworth ABS pump for power brakes to replace the standard servo
And finally took it for a test drive, what a beast! Only made 3 PSI @ 5200rpm, but it certainly pulled hard!
Was expecting a bit more but its likely the engine is breathing better than expexted (already verified pressure reading is correct and no leaks) so swapping to the smaller pulley and will test again on monday.
thats getting really interesting under that hood ...
nice works Stu
I bet that moves and with a great soundtrack as well
could you not run the Air filter under a wing so it doesnt get so much eat to it
its now Monday ... ...
its now Tuesday cough cough
Apologies for the delay
Unfortunately a brake fluid leak has prevented any further testing for the moment. Hopefully fix that this week.
Watch this space
urgh.. sorry to hear ,,
that brake M/C conversion?
hows that bolted up then ..
and whats the pump & M/C off, thinking it would originally be an ABS thing, but not any more.. how does it work on the pedal?
still a solid pressure, or does it recirculate like the normal ABS BS ..
MC/ABS setup is from a Sierra cosworth.
Mounted using original brackets welded to an adaptor plate (plus the pushrod has to be trimmed/threaded to hook up to the capri pedal with a rod end)
On the sierra cosworth setup the pump/mc is independant of the ABS control unit, so can be used without it.
The port that would be the return from the abs control is blanked off, then just use the other 2 ports on the MC for front and rear brakes.
Pump is triggered by a relay controlled by a pressure switch on the unit itself. It runs until pressure is built in the accumulator then shuts off (and tops up when necessary as the brakes are used)
Only been on a short drive, but feels good, much like a modern car, doesnt require much pedal pressure at all for normal braking
nice one Stu, hopefully see you again at a show some when in the future
good to hear Stu need to catch up been a while since we chatted
Glad to hear its running healthy mate.....now get the G meter installed lol
Bit of a while since the last update,
Evnetually sourced a 100mm supercharger pulley, so car is now making 6.5psi boost @ 6000rpm, bloomin well shifts now!
Unfortunately pre-MOT inspection revealed that the dreaded tin worm had set in too much for a pass, so major bodywork has insued............................
Shall be tackling all of this this week, so watch this space!
fook me that inner arch is a bit rough aint it, looks like my old vauxhall magnum
He has a plan I think, be solid very soon I imagine
fitting Mickey Thompson tubs lol
