Overall better - BMW Forum

Okay, heres the deal. First off, I just raced a 2001 M3 coupe with SMG, and I beat it, it did good, but I beat it. Ofcourse if he knew what he was doing he would kill me, but I walked away with the win. When we pulled over and were just sorta talkin my car was real hot and I had to put the hood up and just sort of let it breathe. It was kinda steeming. I was wondering what would overall let me take my car to its normal redline or near it, and hol dit, without letting the car heat up a lot. Would a cold air intake, or any other intake cool the engine faster, not so much for power, but allow me to keep my car at higher RPM's without heatin the shit out of my car. please post your opinion, and what might help my situation.

Logically, if the car breathes through the intake, and you get a freer-flowing intake, then the car's going to at least inhale better. An oil cooler wouldn't hurt, either, but I think they're relatively expensive.

If you continued to drive it would have cooled down normally.

If you pull over and shut it off the exhaust is glowing and no air movement so you get a flash of smoke as it burns off the road film.

I have a mobile dyno and it is NBD to need to use a fan to keep the air moving.

I hate to sound retarded, because I have never really dealt with this type of situation before, but, would headers allow the engine to breathe better? especially if their new and bigger, I guess it might help cool a little

Somewhat, but that's not going to have as big an effect (certainly not per dollar, at least) as the intake or exhaust, since they're at the respective ends of the respiratory system. Since your car isn't actually overheating to the point damage is done, you could just get ceramic-coated headers to keep that heat inside the combustion zone instead of leaking it out to other parts that otherwise wouldn't generate their own heat.

first off, check your coolant and make sure its clean and at the proper level. KC is right, you should let the car cool down by driving it normally or softly, not by turning it off or by letting it idle. you should always allow your car time to cool down after driving it hard. CAI and headers would not affect or aid the cooling of the engine, and your car already has an oil cooler.

Im gonna call the bs flag big time on this one.

You beat an m3? I mean come on, theres no way to beat it in the straights, especially an SMG, even an woman (no offence) can drive those. I was up to one the other day and from a start, doing a complete launch and full throttle up to the 80 onto the highway. And he didnt realize i was going at him. He was just cruising and he pulled away by about 5 car lengths. They have those huge tires in the rear for a reason.

And where would you be racing just a spare m3 on a non track area but doing solo II handy work?

Engine steaming, at redline? I dont think so not unless you have water all over the block. I run my car in the top of 2nd, 5000, 6000 rpms all day long and the temp doesnt get above the 2nd peg.

dude, not striaght, through a canyon, it was pure driving skill, but he was flying and I was pushing the car as best it could, and I finally beat it, ofcourse with the right driver hew ould have killed me. but this area was pure skill and know-how, I fucked him up.

and my oil temp gauge wasnt over, I think the engine was just hot, dude, its not like I am foreign to the racing bizz or keeping my engine high. the car was just plain hot, it was like "TTSSSSSSSSSSSS', it wasnt steaming a lot, or makin a steaming noise, just some steam type stuff was rising, nothing on fire or anything, it was just letting off some steam.

and again, the race WASNT going straight, it was in a canyon, about 20 mile long deal.

wow, a 20mile canyon run sounds like a blast. if you were hearing a tssssss sound then it could possibly be a hose seeping. check the braided coolant hose going into the radiator or possibly somewhere around the intake mainifold next time you hear the sound.

The later E30 came with oil coolers from the factory.

explanation satisfactory, bs flag withdrawn.

spiff325is · 03-28-2004, 06:18 PM

yeah there ya go, lol. Fox, you should have seen me, I was flying. I stuck every turn so nicely, my brakes were doing so well, but bigger ones would help, say...dual caliper cross drilled discs maybe?

Fox · 03-28-2004, 06:46 PM

LOL no why waste all that money. Just throw on a 7 series master cylinder. If THAT isnt good enough (then your dumb) er i mean throw on some mintex red box pads.
