I think the question for forced induction is really if the car is designed from the factory for forced induction. If it is, then it should run fine in all conditions. Would I add it to a normally aspirated car? No way.

I would not. The M3 is a high compression motor that is already pushing its limits in terms of design and horsepower. I want to keep my car for over 100k miles of reliable driving. I don't think it will be as reliable with the added stress of forced induction.
If you want a turbocharged or supercharged car, it is much better to start with one that is designed with that from the factory. They put a lot of research and development into building the motor to accept boost as opposed to bolting on something to an otherwise stock motor. |

I think I can speak on this in a general sense since I've been tracking my s/c'd E46 330 for a while...3+ years now.
Vendors can say what they want, your car will be down for repairs and maintenance more often. Coil pack, spark pulgs, belts, cooling issues, driveline mounts, and anything bolted to the engine takes more of a beating and will not last as long. You have to take the other systems of the car into consideration. Brakes and cooling MUST be addressed for track use. Its an issue running NA. Then you have to drag meth (or water/alc in my case) to the track if that applies. It is just a massive PIA running FI at the track over the long term. I would not consider FI for my E90 M3 if I were to take it to the track. I'll bet that no FI system on an E9X M3 will last very long in the Texas summer heat because stock NA M3s can't run flat out for more 20-25 minutes.

I'd suggest saving your money and getting another car that has the power you want or get a tuner friendly car such as an GT-R or Evo where you can add power with ease since it is factory boosted. |

Company's that create or sell these products will always have good results. DIY masters will also report never having an issue on track. That's because they know what to look for and address "band aids" before it ruins there track day. The average gear head wants to just jump in their car regardless if its been sitting for a few weeks or few days and just DRIVE. OP take a closer look at professional racing. The only 2 choices are NA or Turbo. No one races (and never has) a centrifugal blower or even a roots type and wins consistently. You can listen to the ones selling you something. Or the average guy who was a customer and speaks from experience. I had issues with heat soak and belt slip and cooling leaks on my blown S52 e36 M3. All that power and torque being generated by the blower (plus heat) and your snapping the throttle on/off on the track and the only thing holding all this released energy is a sc belt. It's a very harsh situation for the engine. A turbo motor can release this energy with much less stress on the motor. Personally I love spending time on track and will likely never go SC. A twin turbo S65? That may bring me back to the dark side.

Search for Mike Benvo. Btw that's plenty of power on track. No one likes those guys that blast ahead on the straights and then pussy-foot their "high hp" car through the corners. They just end up slowing everyone down.

I figure I'd rather drop the 100 lbs of weight that the supercharger puts on the front of the car at the track.[/QUOTE] This kit adds 100 lbs to the front of the car? |

i have gone na to fi before, ultimately i came to the conclusion that if i want more performance out of my car i should shop for another car that will satisfy my needs. it seems the upgrade path never ends. intercooler, oil cooler, meth injection, race gas, cooler plugs, so on so forth. NA is better for me.

I'm planning my first track day this month with ESS 600 and will be
interesting to see how it goes with the high AZ temps. If heat is a problem I'll add the M24 oil cooler. I love having the extra power of the SC and added nimbleness, it would be hard for me to go back as the SC really transformed the car. While unnecessary and perhaps less optimal for the track the SC has really increased my enjoyment. This summer I experienced heat soak limp mode within 10min of driving the new M5 (F10) hard at M school on 95F humid summer day, hope the new M3 turbo's are better in that regard. Cheers, Axis

I think I know how your track days will go even after the added cooling measures, but I think the forum could find it useful to know how these setups perform in conditions as brutal as AZ. Keep us updated!

I posted that with tongue in cheek, except the bit about the costs. As posted earlier, best to stick with a power train as close to stock as possible IMHO. Event chipping a turbo car is asking for expensive trouble in the long run at the track.

Many great replies.
I think that 90% of SC owner don't track their car "REGULARLY". I also think that the SC adds tremendous amounts of fun to the car, and increases daily drivability (added power and torque). Unless you think you live on Mars, it would be hard to ingore the fact that SCing the E9x will shorten the lifespan of the engine. However, that being said, if you think about your daily commute, most of us are on WOT at most 5% of our drive. So, unless you track your car all the time, I think the fatigue factor is a very small issue. I'm itching like crazy to feel the power of a SC E9x. Perhaps its for the good that I haven't experienced this yet, or I would be hooked. |
