For you supercharged guys...

Did the supercharger alter the confidence you had when driving the car hard?

The reason I ask is my brother just got a c7 z06 and I took it out tonight and gave her a good beating. Amazing what Chevy has done there but..I left with one major complaint, its mostly useless on the street. Its too powerful.

I couldn't come out of curves and stab the throttle and just go until the next one...even with TC on, it would break traction easily, whether going straight in 2nd or 3rd gear...or coming out of a curve or even staring at the car, it would break traction lol

Does a SC kit make the e92 m3 kinda useless like this, or does she still maintain her stable character, just faster?

SC'd M3 is still an M3 and will never be confused with a high torque Z06 although will have similar HP numbers. Max torque will be around 400 ft lbs (350-ish to the wheels), so you can definitely break things loose in the lower gears, but the car's characteristics remain pretty much the same until you get into the higher RPM ranges. That's where things can get a little hectic.

So, to answer your question, no loss of confidence, you just get where you're going a lot faster.

The supercharger increased my confidence overall, because I can now really push ahead in street situations without pushing the car to max rpms. I would agree that you cannot really use all the power in every situation on the street for fear of arrest or loss of traction;-), but the beauty of these kits is they don't really change the drivability. You can take it easy and it drives like stock or mash it and you have a race car. When you mash on the throttle when the RPMs are above 4k on the Harrop, you can spin the tires, even in 4th gear on the freeway. You have to take this into account and apply power accordingly.

I love my harrop kit, and encourage others who are on the fence to go for it!! I waited for 5 years to do it, and considered just selling and getting something different. Im glad I didnt, as the addition of the SC made it like a whole new car with the comfort of something very familiar. Now shes even more fast, loud and a real head turner around town.

This is why awd is great in a big power car if you live in an area where it rains or you get temperatures below 70F. My next car will be awd -- probably a Porsche 997tt or 991tt -- for better traction.

Sure, you can learn to drive a rwd big power car. I have a turbo e36m3 with 700 rwhp and no traction control and I drive it year round in NH. But obviously I cannot always use the power.

It is true that AWD makes t easier to get the power to the pavement, and makes balancing a car easier under throttle, but there are tradeoffs. AWD adds weight and complexity, and tends to play some havoc with steering feedback. There is almost no performance car on the market (including the stock M3) that you can really drive at 10/10ths on the street without puttiing lives at risk as well as risking a stint in jail, so the secret is to test drive a car the way you anticipate driving it as the owner, along similar streets, and see how much you like it. The same is true for adding a supercharger to your car. Find one with the kit already installed and see what you think.

If I keep her, I have a feeling that SC will make me fall in love with it all over again...I definitely enjoyed how powerful that z06 was but I missed how stable the e92 was. Granted this could have had something to do with temps being around 60 degrees and his tires not being able to really get up to temp but man that thing is just scary fast sometimes.

The best of both worlds would be ideal. My e92 has 85k miles now though so I'm on the fence about slapping a SC on it at this point.

When I was driving his car I was actually thinking something similar, not necessarily AWD but something from Porsche where I've never felt afraid to dig in! Granted I've never drive a Porsche as fast as the c7 z06.

997TT or 991TT are 3500 lb cars -- less than most E9xM3 and they have AWD, 4 seats, handle well, and can be modded to more rwhp and torque than the E9xM3 on a stock block motor. But they cost more. It's a step up -- $70k-125k used. I may supercharge my 08M3 in the meantime while I continue to dream about the Porsche.

I'm at the point between investing more money into the M3 and using that to get into the Porsche.

I want a 991 GT3 however and I have a year plan in mind.

Honestly, the M3 is useless on the street unless you are okay with breaking the law in a major way. My VF620 E92 is okay until the car comes alive at about 7200rpm.

What I meant, mostly, is that I can come out of a curve full throttle with DSC off (then let out before I'm going 100).

Going full throttle in the z06 in any circumstance was pretty much begging to spin and or die lol

With MDM on you can rest assured you will be fine, though car will likely want to intervene, but traction off you had better have the wheel close to straight before hard throttle, or you will lose the back end.

You can speed in a Prius. Some people speed, some don't. If you don't, the M3 is a waste unless you track or autocross it. I'd guess 5% of owners track or autocross. But I don't think that means 95% of M3s are a waste. I think at least 50% of owners speed at times.

I'm at 85k miles now and SC'd a year ago at 75k. No issues so far.

Did you do rod bearings at the same time?

Did rod bearings a year earlier than the SC. Roughly at 65K. They didn't look too bad but glad I did them. Went w/VAC & ARP bolts.

Theres a guy up near me who didn't do his SC until like 84k miles and he was fine too. I guess its not so bad.

A lot depends on the SC you choose. ESS 550 can be a bit tamer than a 650. I had a ESS 600 (back in the day that was the mid range model) with my e93. The extra weight of the convertible, and the power of the SC, struck a nice balance with little wheel spin, yet still get 0-60 down to 3.7. When I switched to a 650 the extra power made the wheels spin much more easily and one had to be much more careful.

I'm really close to handing my car over to iND Industries and letting them SC it, and whatever else the see fit to do to it over the winter. They're big into the ESS. I'll go with the 650... They do the rod bearings AND custom paint job on all ESS installs.

So much money though.

I find my car feels lighter, like it?s just revs more freely from 2-4K rpms I also find I don?t push it as much .

This feeling is less evident in the smaller kits (550 ) Since it makes less boost earlier.

The power is so linear, it feels nice at low rpm. Great setup!! Extremely drivable.

Interesting, because the centrifugal adds very little power in the 2000-4000 rpm range and is essentially another accessory adding a little drag on the crank even when the bypass valve is open.

At 4K rpm I?m building almost 2psi of boost . 3psi at 5krpm . This is just enough to make the car feel lighter and more responsive .

Old thread, but is this still the case with those running 275-295's in the back?
