supercharged e30

[Bmw e30 Justin]

That video is so stinking old it's silly.


As far as the exhaust note goes it's too loud for my liking but car looks like it's running great. Any fueling issues?

Yeah its loud but its just a weekend toy so it doesn't bother me. What do you mean fueling issues? I'm running 42lb injectors and had it tuned around 11.5 AFR's across the board....

Justin your car is sick! We need some footage of it against some suitable competition (e92 M3s, e60 m5s, c6 vettes). Get on that ASAP! :twisted:

I agree with you!! Ever since I boosted it no one wants to mess with me I have to start everything! The car is pretty damn sleeper most people are just like o look there is a nice older BMW. The best car I have played with was a SRT8 300c. We started off at a redlight I let him "start" the race by going first, He pulls a quick 2 lengths then I shift into 2nd and start to reel him in and he lets off (1 length away now)...... I was like damn it 2nd and 3rd are where my car shines.... so anyway my 265Wtq was no match against his ground ripping 420tq off the line

But anyway thanks for the comments

Really?

You should be able to eat an SRT8 for breakfast with a good launch. From a roll you would definitely destroy one, I used to pull about a car length on the SRT8 variants from a roll at various speeds in my swap car with only 232 whp/ 228 wtq.

What gearing and trans are you running? What size tire? What spring rates in the rear? Also are you running s52 cams?

sounds great! like a cat with the power of 10 bears!

stock m52 cams really kills the powers up top.
centrifigal chargers really suck balls in first gear also all it does is steal parasitic power from the engine and doesnt have any time to push any boost.

m52+zf320+3.15+205/50-15

rear springs are around 750

its not a traction issue in first jut not long enough of a gear to built boost

+1 on the cams, the s52 cams and a re-tune will REALLY wake up the top end, especially with the blower! :-D

Gears aren't too short necessarily, that's a great gearing combo. If anything 2.93s would be better.

Tire size is pretty undersized for the amount of power being put to the wheels IMO. Some wider wheels, with at least some sticky 225s would help a lot.

Depending on the compound of rear end bushings (IE - rubber, soft poly, hard poly, or delrin) the 750 spring rate may be a bit too stiff. I was running street compound poly urethane subframe bushings and trailing arm bushings, 19mm sway, along with billy sports and e36 m3 H&R Race springs (570#) on my swap car and it was perfect for both launching, and corners. When I had 700# coilover springs in the rear, it was TOO stiff, and the rear end wanted to go everywhere.

The polyurethane bushings really helped with traction. Justin if you haven't done those yet, then that should be your next mod!

Yep I cant wait for cams :p

I have AKG TABs and Powerflex subframe bushings. Traction is not an issue at all. Hooks up really well on the set-up I have now. New tires will be Hankook RS3's 225/45/15 but they were backordered to hell when i bought these a month again. Nitto Neo-gens are what I went with and its a great tire with good grip.

Glad to hear! Bet your car is a fuckin blast to drive! :D

The cams will really wake it up after 3k! :woowoo:

Yep now I'm just debating on what cams to go with..... I think VAC supercharger regrinds should do the trick but how much would i pick up with stock S52..... Its a guessing game really.

Those VAC cams will cost more then the gains that they're worth. I'd say just go with s52 cams. NA m52s usually see about 20-30whp from s52 cams, injectors and a good tune. I'd imagine an even greater gain on your set-up.

The nice thing about the Motorsport cams is that you don't really lose any bottom end torque. The supercharger cams may cause you to lose some power under the curve, where you really need it.

Sounds like you've got a thing for 3" tubing.
