Does your drivers side exhaust manifold touch your brake master cylinder? It look ssoooo close.

Of course not.

Was just curious, i just swapped my manifold for one thats closer to the master cylinder rather. Than being super close to the steering return fitting.

I cant figure out why my brakes arent cooperating with the hydroboost on the 302

It's only been 2+ years since I drove it last. Finally gave up ever being interested in working on it in my small shitty garage so called in a favor. New turbo is installed. New trans installed. Started it this morning. Sounds so good Need to figure out what happened to my clutch pedal since sitting, prior to driving it again. Really interested to see how much more power it makes at the same boost level with the appropriately sized turbo. Oh, and new synchros should be great too.

YAY!!!

Drove the e28 for the first time since 12/16. It's going to be a good driving season! Too bad it was snowing. Took it really slow on my 140 treadwear summer tires.

That car makes me smile too.

I have been really enjoying the car lately sorting through some issues fueling issues. Got that all fixed and decided to put it back on the dyno. Also wanted to find a turbo LS expert to help tune it. I was able to do that this week. In addition this dynojet was load bearing. Spent the first 45 minutes cleaning up my spark advance table off boost. I wasn't even close to optimized in some areas. That was a big learning experience. Unfortunately the two 35 year old plastic bushings in the throttle pedal bracket disintegrated during the second WOT pull and made the return unreliable so we stopped. Didn't even get a full 7000rpm pull in.

Just to recap, the engine made 503/485 in 2016 at same boost level. Boost averages a shade on 10psi. Max boost was 10.8psi. This is unchanged. Turbo was upgraded from a billet 67/65 1.15 exhaust housing to a billet 72/79 .96 exhaust housing. Car picked up 40rwhp and I think there is probably another 10-15rwhp in the tune.

Tires spun on the dyno on the 2nd run. Going to need to figure that out for next time.
