Sweet! I've read your build over on bimmerforums.com but at the time every pic related to megasquirt wasn't working :-[

I can't stop looking at that car. Really nice job on it.

hows it runnin with the megasquirt? why did you have to mod it for bmw ignition?

Re: Turbocharged '92 BMW 525i
 

beautiful. So you're running a H1E on a 2.5 liter engine, how is the powerband??

Sick ----!

Re: Turbocharged '92 BMW 525i
 

Nice work!

Looks like a really clean and well done setup.

How much power are you making? How much boost?

Re: Turbocharged '92 BMW 525i
 

In first gear I get the push of boost around 5k rpm, 2nd gear around 4k, 3rd is like 3700, 4th is around 3500, and 5th gear at 75 mph if I floor it, at 3k, th car pulls fine until about 3300 rpm when the torque comes in and the revs fly up as the clutch lets go. So, in 5th, I am seeing full 10 psi at 3500 rpm or so. Its a laggy setup with peak power in mind, not so much "linear pull." The car is very fast and violent - pretty fun and intimidating to drive.


As for power - I won't know until I hit the rollers. My tune is pretty modest, but I will hit it up on the dyno. I need to get a clutch in her first. That's coming soon.

Re: Turbocharged '92 BMW 525i
 

I guess I have two questions.

1. Where did you get the ford/bosch 42# injectors?

2. Why did you go with a tiny ass sidemount lookin cooler when you went all out on everything else?
