Cambelt cover was specially made.
As for engine, it is being run in and getting map later this week. It's working on the map that was set up for the T61 with slightly different specs when it had a bigger housing.Audi 90 quattro (Typ 85)

Super news!!!! Off...i want to feel the same as you now!! Jesus!
I will come to UK...but...i had no time and money to finish the engine..taking in consideration the fact that the body is at body shop and is taking alot from my walet...
So probably....next year in summer i will be there.
I'm really glad that your engine is finaly on the dyno!!!!!
Goodluck!!!

Definitely surge. Screamer pipe not being fed back into exhaust to minimise boost while the engine is being run in. Once the pepe is connected properly and Ahmed tinkers around with the maps, surge should not be an issue.
At least I hope not

TA DAH!
Engine has been mapped today YIPPPPEEEEEEE!
Running 30psi boost, I am down on power slightly on before with 470bhp (530). Restriction mainly due to air flow, so either down to Inlet or Exhaust Manifold (probably the latter). Given that Jyrki supplied me with a manifold for more low down response and that is what I have, I am happy for now but will reserve final judgement for when I drive the car again. Sounds very promising though as pulls strongly from 2800 - 3000rpm.:tup:
I will post up a graph with results shortly.:tup::tup::tup::tup::tup::tup:Audi 90 quattro (Typ 85)

Got a dyno plot sent through today. A different air filter was put on a some tinkering done which resulted in slightly improved results. As stated, flow has made a difference.
Just for comparison, here is the old plot and the new one with the smaller housing.

A bit better one would say. When even the old setup was not bad. Grats dude, lot of hard work and a long wait, maube this makes it worth while.
Almost double the hp at 3500rpm.
3000rpm worth of +400pound of tq. Nice.Everything less than 2 bar is considered to be naturally aspiratedComment
