Superchargers
Hey guys, i know there a bunch of threads for superchargers and engine mods but i cant really get the answer Im looking for, So i just wanted to start a fresh thread. How many people have successfully made a supercharger for the M3? Is It worth getting one? Thanks

GPower I believe is the only tuner out with a SC kit as of yet. It is however expensive as hell, about $25,000 for their basic kit that produces about 530bhp and about $40,000 for one that changes all the internals and produces about 600bhp!!
Serveral other tuners are working with FI such as AA in the United States, it is however unlikely that these kits will produce over 510 to 530 bhp without working the internals of the engine as these machines can take no more that about 0.30 BAR of boost or risk damaging the engine. It is also unlikely that you will find anything reliable out there even when these kits are developed for less than $15,000. I think more around $20 grand.

How about a Dinan stroker with a warranty?

That will be at least $30,000!! I like keeping it NA and these Dinana kit will produce plenty of hp and additional torque, but I think this one guy wants FI because of the lower potential cost.

With the forged internals, low compression pistons, etc... VF engineering should be looking a huge power gains but also huge $$$$!

The Hamann Thunder was featured in Bimmer magazine which was a 325i or 328i totally reuilt with M3 everything and a 550hp V10. They only had 0-60mph which was 4.3 or 4.2 I believe and then went on to say that traction, weight and aerodynamic drag were the limiting factors.
That car did have 305s on the rear. I'm wondering how much of an improvement a supercharger kit will be? I supercharged my 330Ci and that was a huge difference. I'd hate to spend $10k+ on a marginal improvement. I'm sure it would help rocketing out of tight corners on the track but what is the use if you can't put the power to the ground? DISCLAIMER: I just read this...really not an expert on this.

Anyway, if you keep the engine NA with a stoker kit, you actually do avoid all these issues as the front of the car is made a tad lighter but you get all that additional power and retain the absolutely great thottle response. FI will undoubtedly add weight albeit perhaps at a lower cost. Although I really doubt anyone will come up with an under 10K FI kit for these cars.

I think VF's kit should be reasonably priced and should be out soon. We cannot expect that much of a gain (500 to mid-500's) because of the high compresion ratio. I think we just have to wait to see what these engines could handle and the drivetrain could handle. Like the S54, at first no one thought it could handle alot of power, but until people started pushing its limits did people realize what a strong motor the s54 was.

On stock internals I am expecting 525 rwhp. I mentioned 600 wheel as to what the internals were capable of handling, I don't think any supercharged E46 M3 hit this number, the turbo cars did. Either way, it is going to be fun to see what happens. |
