Some news on the car :)
After reading the posts on Dave and Adie's car, I went to SPC Horsham which is conveniently next door to where I leave as I have the same FCON symptoms: non working fuel guauge, car not starting first time, big black smoke when accelerating obviously overfuelling. I know the car was running rich as I asked TDI to map it so it is safe for the engine.
After a chat with Phil and Wayne, we put the car on the dyno to see how it goes.
The results were very interesting indeed, on 3 runs the car produced 196bhp and 160FtLb torque which is almost what I got at the TDI meet last year. Unfortunately there is a catch. The values from TDI are supposedly at the hubs whereas the ones at SPC Horsham are at the flywheel ... They measured the intake pressure, temperature and lambda at the exhaust.
First of all the boost pressure is at 0.25bars not the 0.45 that I have been told it was thanks to the Katana intercooler.
With a boost pressure almost the same as a standard TTE or slightly lower, it is hardly surprising that the car is in fact producing less than a standard supercharged one.
The lambda values showed that the car was running very rich all the way in fact it was richer on the low end than on the top end ...
To say I am gutted is an understatement, I spent £7000 to add parts to my already supercharged IS200 to make it run worse than it was before :tsktsk:
I decided to leave the car to SPC so they can try sort things out.
I just picked it up this evening, it is no longer producing big black smokes, the lambda values are now sensible and it produces 10 more bhp all along the revs. The torque has been increased to a constant 190+ FtLb from 3200 revs. Phil and Wayne told me that the fuel gauge issue should be sorted soon as they are working on it. Ike who did the new mapping told me that as long as the SC speed does not increase, there is no way I can get much more power than what it is supposed to produce which is 200bhp so the only way forward is a bigger pulley which I already have thanks to Prolex, I just have to wait for the stroker kit to be available now :P
Overall I am very thankful to SPC Horsham, the service has been very friendly and efficient. I would highly recommend them to anyone.
