How really fast is a S52 or M50 E30...

[bimmer_E30]

i`ve heard they could actually beat a stock E46 M3....is that right lol

[rThor432]

Um yeah. Well, actually after looking at the numbers it doesnt make much sense. Well, mine is faster @ 260 hp/2450 lbs. It's been proven a couple of times anyway.

240 hp/2700 lbs. vs. 333 hp/3400 lbs. <------These numbers are vague and the flywheel horsepower of an OBD-1 S52 with a proper tune should be up a decent bit from that, especially with the hot rod bolt-on's.

Yeah my car is alot faster then most e46's but I have a gutted inside so my car doesnt wieght that much.

My s50 e30 can spank even a C5 Vette.
I can't say for any of the US s50 swaps though.
s50b32 ftw

you only gain 1 second for every ten pounds removed... right?

[bimmer_E30]

shit. that would be cool to spank new cars with an old boxy car.

I wish I could have gotten one at the time but I am just going to run my s52 till it pops. Then putting the turbo, arp head and crank studs, gasket, forged pistons, and vems :twisted:

Its 100 pounds I think.

C6 Vette couldnt pull away from me on the highway, so the US 3.2 litre has been spoken for. (Not a lie, and yes, I was surprised). Didnt spank him though, at all.

I would really like to track down one of the real M motors though...

and it's a 10th of a second

[Vince30]

I think its 1 tenth of a second for every ten pounds or something closer to that.

[rThor432]

Hmm never heard that. I know the general rule of thumb that 100 lbs. removed is about the same as freeing up 10 hp.

No way.

[e30slut]

lol a tenth per 100lbs

[Fidhle007]

I was dead even with an E46 M3 through 4th (70 mph roll, closed course, professional driver, don't try this shit at home kids) and then in 5th I started to pull away ever so slightly. I attributed this to my shorter gears though...

Motor: 3.5" MAF, TMS chip, 21.5lb injectors, headers. ZF tranny with a 3.25 rear end, my car weighs in at about 2940lb with me in the driver's seat and my day to day shit in the trunk, back seat.
