No, x42 dash 3.5 slash 48, stroke 15 raised to the 32nd power, I believe...Just throwing something out there, I read u can run stu at 3200lbs with a 3.2, did they say it as to b a s52(3.2), or a s54(3.2), 3.2 is 3.2 lol
took your advice n read the rules, u r correct, but what i don't understand is if i choose to run 2001 330 (3.0) e46 bmw i have to weight 3300lb, but i can also run a 99m3 (3.2) at 3200lb, with the mods allowed n what can b done to the 3.2 motor, it's gonna b interesting to balance all these carsNo, x42 dash 3.5 slash 48, stroke 15 raised to the 32nd power, I believe...
I have no idea what you're talking about, AJ . You need to read the rules since you're responsible for making the car legal. But, the 95-99 E36 BMW M3 engine is allowed in STU at 3200 pounds, but is only allowed .040" overbore, 1/2 pt compression increase, and has to use stock camshaft lift. Read the December Fastrack for the latest iteration of the rules...

Yer tellin' me, bro..."interesting" is a nice choice of words......it's gonna b interesting to balance all these cars
It's > 3.0L. If we're gonna make it a free-for-all for any cars over 3L, might as well run them all into one class and call it, I dunno, "STO"?The tough pill for the M3 motor is it must have stock cam lift. I thought that sorta porked the x WC cars that this class was made for, no?
it's gonna b hard to beat a well built 3.2 s52 motor,the rules say u can go .5 lift, .40 over bore, most full race cams, vac (.407 lift, 286/272 duration , evosport, sunbelt, r more duration cams,there r stock 3.2 out there with evosport cams making 280+ whp, with a good usuable torque band, so if i was to max the rules out, more lift cam, .40 over, deep pocket piston for the higher lift cam, porting to what's allowed, according to the rules i can run bigger cams than i'm currently running, for reference, a nasa gts3 bmw with a s52 with cams, weighting around 3100lb turns 2:09's at the glen, they have more aero stuff, knowing what i know i do believe the stu limit should b set at 3.0, the limit for the wc touring cars were 2.5 n 2.8 if i remember correctlyThe tough pill for the M3 motor is it must have stock cam lift. I thought that sorta porked the x WC cars that this class was made for, no?
Read Da RuleZ, bro! If you enter the 95-99 M3 ("S52") engine in STU, you have to run stock lift camshafts, which on a quickie Google search reveals they're 10.2mm (.4015") lift stock...and you can't go to 12:1 compression, only 1/2 pt over stock, or 11:1.it's gonna b hard to beat a well built 3.2 s52 motor,the rules say u can go .5 lift, .40 over bore...
i'll b watching too, no more stu for me, i know phil n fred won't like that, but i think they r on the fence too, i'll b running with the guys that do the space programRead Da RuleZ, bro!

those damm rules,i gotta read them u r right again,i need to stop reading quotes (that's where i got that .5 lift from) the stock cam is .401 n a commonly used race cam has a lift of .407 a diff of .006, after wear n tear n measuring error, talking about cutting it closeOn edit: DISREGARDbackground on that. - GA
I can offer you this on a personal perspective, Ben: both cars start with 240 stock ponies, but the 968 has room to grow on compression, since it's 8.3 stock and you can go to 12:1. The M3 starts with 10.8 and can only go to 11.3. How are the cams between the cars? You can go up to .5 lift; that's the stock cam on the E36 M3...?

I'll defer the facts to you BimmerHeads. I'm only pointing out that the 3.2L approved engine has build limitations that 3L-and-under engines don't.If you read the section on the M42 sport cams you'll see that they claim two different lift spec's 10.37mm for the intake and 9.7mm for the exhaust...

Personal opinion: I'm not pleased that the 3L "line in the sand" has been breached in STU; let's not go overboard and rub sand in the face here by missing these prescribed limitations... - GA
James, forgive me if it was inferred differently, but in my mind this is not a "BMW Thing" in any manner. And I do sincerely defer the facts to you that know.Just remember that the line wasn't originally crossed by a Bimmer, but rather by the Nissan VQ.
Yes, IMO. Audi is a family member of VWoA, as is Porsche, Bentley, and whom else...?If one can swap engines and gearboxes between Acuri and Hondae, can the same be done with VWs and Audis?
Yup. Or 6th, even......one could mix and match from stock parts to get whatever 1st to 5th ratios one wanted...?
