Hey Bubsy, we boosted to 10 PSI before having any detonation issues, we were not running at 10 PSI, brought it down to 7PSI.

I am really busy today so can't respond in detail. I had 2 extra boost injectors supplying extra fuel with an EIC seen here http://sdsefi.com/eic.html which is a micrpporcesed Extra Boost Injector Controller.
Please go to my website for the details. We were running within very safe A/F ratio limits at 9 PSI but were telling all interested parties to run at 7PSI

I was doing this project with one of the best turbo experts here, he has a shop and supllies all the other turbo shops with turbos and accessories.
He is an icon in the VW turbo world building turbocharged race cars and was helping me with the BMW kit development.

Our m20 stage 1 kit was a success and now I am onto the e34 m30 for my e30. Have a friend in TO delivering 350 RWHP on his e34 m30 right now (daily driver) on a 300,000 KM plus stock e34 and now rebuiling a complete performance m30 for his car, so taking allot of notes from him. I am now rebuilding the m30 in prep for my turbocharged e30.

I have started a new website for my all of my BMW projects including the m30 turbocharged swap and will be documenting everything over time www.turboready.com The website is far from being what I want but all I can do for now as time is so scarce.

Cheers and thanks for your input

8.8:1 compression helps too.

We are not talking about too much boost, we are talking about hot air going straight into the engine without any type of cooling.

If you look at 745i Turbo
It has even lower compression ratio, 4.4psi of boost and it has an intercooler.
Running 10psi turbo with no cooling whatsoever is suicidal i think.

I was going over your dyno pics. You put down 139 hp to the wheels. was that on the stock motor or the turbo motor?If that's on the turbo motor I'd call that a BIG failur.
BTW I'm running 9psi on my M20 motor with stock internals and its putting down 270hp to the wheels

Thanks buddy

Haven't dynod it Estimating around low 300 rwhp at 10 psi will be going up to 15 or more after the couple of changes.

For managment I'm using DTA FAST P8PRO still playing with the tunning.

It was 139 RWHP STOCK, read please bro. Never got a chance to dyno after the FI setup, but I am sure I was around high 200's as well. I had no traction between 1st, 2nd, and 3rd gears, spinning wheels right through. It was late October when I was done and it snowed soon after so never got a chance to play with the 2.5 m20

I am now rebuilding the car from the bottom up doing a 5 lug e36 318ti suspension swap with GC Coilovers. I will try to get 245's fitted at the back for traction for the e34 3.5L turbocharged motor.

Not much right now but after im done building her she should put down some sweet power+exhaust notes

stock jspec 4agze (supercharged) 16v DOHC 165hp@6psi
plans : either run dual set up (td04 / s/c) with hks oversized pulley to run max boost on s/c (10psi stock s/c)or single turbo,greddy boost controler, custom manifold/full race exhaust (exit out liscene plate), replace top mount intercooler to side mount by air ducting.
