So another long awaited update, the engine was fitted and cams run in. I then had a pause due to going on holiday etc etc. on my return I finished all those little jobs that aren't much but seem to take loads of time.

Then came the running in process, now my car has been non road legal for a while so I took the decision to have it run on a dyno to carry out the running in process, luckily I have a good friend who works at a place called AET motorsport based in Normanton about ten minutes from my house. They're a turbo specialist who tune a lot of rally and time attack cars and have a good reputation So yesterday I loaded the car onto the trailer and took it round for the much anticipated running in time and power run on the end.
All in all it was a mixed day, the engine run beautifully and really sounds well but the run on the dyno has highlighted a few issues..... I'll let the graph do the talkin in a minute. So the next plan I think will be to contact Wayne at chip wizards and go over and have the map tweaked to see if the issues can be ironed out seeing as the ecu on the car was mapped by Wayne originally.
A few photos from the day,







My question is, what would cause the torque curve (green line) to be the way it is?

Yep, i checked it 4 times. I do have a suspicion though that the ecu was mapped on a car without pocketed pistons so the cams would of been 'retarded' and therefore it throws the whole map out. As all I bought was the cams and Schofield mapped ecu so I'm thinking it needs to go back to Wayne to be altered.....

It's a pugsport mate, I'm not entirely happy with how it's sitting at the min but it needs some new mounting rubbers then il look more closely at getting it properly aligned!

could be something with the mapping as you can see the afr wavering at the same points as the torque, I would double check the timing regardless though as it peaks a LOT later than they tend to, and the power doesn't fall off at the end after peaking, and you can see the torque plummets so its just making lots of noise and heat after 6200 and not really pulling much.

a decent mapper wont take long to get the timing to spec if he knows the engine.

hub or guesstimated flywheel figures?

It's a guesstimated flywheel figure using 12% correction iirc, it's a Schofield map so I'll probs contact Wayne and see what he'll charge to look over and correct it. I had a feeling it would need tweaking anyway....

I've never driven on the road with mine but I went in khj100's old Rallye, which is now owned by Another forum member and as I recall it was okay! Smile

AET are good guys, our championship uses them for the Northerners to get their dynos done.

Pretty much exactly what I want to do with the race car's engine. Pugsport sounds good as well, will need to get one Big grin Any idea on DB levels?

The pugsport will get you on most il trackdays for definate, as for the DB level I'm not sure but around 92 I think.... I know Kev had no problems with the one on his Rallye!
Yeah they are good at AET, like I say my mate works there and it's about five minutes from me with the trailer on, the get some cracking motors in there!

SO..... Five years on.... its finally running properly! I ended up removing this engine due to it being unable to idle properly, this was traced to being bad valve seats. Although they seemed to lap in ok, the valve seats apparently some were concave, some were convex... either way it wouldn’t idle due to bad compression. Fast forward a bit and I had the engine in two pieces still. Having bought a new house and various other things I got back round to sorting this out. I sent the head to an old school engineers shop near me, they recut the valve seats and the refaced the valves, pressure tested the head and checked it for trueness. It was flat and ready to go. I refitted and prepped the engine for refitting.
Around this time I met up with an old forum member who now is becoming well known for his turbo conversions (Sebastian Fullick) and got a first hand Demo of what a Turbo car can do, including driving it.... well sorry to u boys who have super chargers, this is a different animal.... I’m hooked and at some point hopefully next year il be going down that route. Enough of that for now, in amongst all this I was introduced to the ‘Megasquirt range of ECU’s. now, Mega squirt don’t really get a good write up in the tuning world. This I believe is down to bad assembly of the DIY kits and a complete lack of understanding. The ready built ecu’s and the software that comes with it is nothing short of fantastic, I’ve seen what Emerald, DTA and Omex etc offer, and whilst they’re good, in my opinion the Megasquirt range is actually better.
The rebuilt engine is now fitted to my car with the 48-45mm tapered bodies I bought from Argentina some 4 years ago with a satchel manifold running 8 injectors. This is controlled by a Microsquirt 2 V3 ecu, the car runs, idles lovely and is now awaiting the mappers. Pictures to follow tomorrow! 👍🏻

I’m going to echo what Dave has said here, if you have a personal issue with Seb take it up with him directly. If you’re commenting after the inane rantings by certain people on Facebook, I suggest you don’t comment again, I have up to now and intend to carry on keeping my thoughts to myself, I know more than most about what’s gone on but I still have no intention of divulging that information on you or anybody else because that isn’t the way I think things should be done. If you’d like to comment on my project Constructively please feel free, if you’re here to slag people off I would request you dont as believe me you don’t know the facts.
*Rant over*
