I am thinking of upping the power in my M3 and spotted this.
Does anyone know anything about g-power?
will the car still be usable as an every day driver?
any idea what an extra 100-150 bhp will do to the performance states (0-60) or the sound?

I think it would ruin the car, especially if you want to use as an everyday vehicle - this is what //M's are all about...! Performance cars that you can use everyday.

I've seen your car at one of the runs and it was very nice and sounded good with that exhaust, but I'd leave it there.

With superchargers you'll loose that nice crisp naturally aspirated power.

0-60 i shouldn't think will be much different really. I certainly find that it takes getting to about 50 mph before i can give mine full beans due to grip anyway. The extra power would be noticable above that but you'll be lost in plumes of wheelspin and going no faster trying to use it before.

Only go for it if your only concern is getting ultimate straight line speed or getting into "Max Power".

But that's just my opinion.

hmmm thanks glad you like the beast!
My thoughs were that also, as all the clips i have seen the car is wheelspinning in 3rd!
Any other ideas to get a bit more acceleration?
Luckily i have no interest in getting into Max power, just crave more! Its addictive!

Have you actually driven one that you pass an opinion?

My brother drives a G-Power Z3M Coupe Evo III with 510BHp SC-ed S50B32 lump. It is his daily driver. The car was built by G-Power as their show car for the Hockenheim Tuner's Grand Prix. The workmanship and attention to detail by G-power is as good as the factory's - right down to the last nut and bolt.

12.1 1/4m on Falken Fk452s at the Pod and 8:00 flat 'round the N'ring is good enough for a daily driver. As long as you are aware that there are a lot of horses under the bonnet and you are not playing silly games the car remains tractable and easy to enjoy.

The only thing to be aware of - G-Power spent close to EUR80,000 building the car - it runs 993 Turbo brakes, 6-spd Evo gearbox, carbon front wings + bonnet, separate gearbox and diff coolers, the engine has custom pistons and rods, a water-to-air charge cooler, custom headers and exhaust etc, ac schnitzer adjsutable (bump/rebound) coilovers, heigo roll cage...

In other words, sticking a big hairdryer on the engine and leaving everything else stock will be a mistake...

Absolute guff. Superchargers maintain the same type of torque characteristic generally.

It really will depend on what they do with cams, exhaust system and VANOS (probably fix it on one position), but it'll still be a pussy cat compared to a high boost turbo application.

You'd expect a significant improvement IMO due to greater torque at lower revs. There's something wrong if your car can't deploy WOT at less that 50 mph.

Have a look at the ESS E46 M3 CSL video's on their site or youtube!

The Q car appeal of a blown BMW is quite nice and it doesn't attract any more attention than you want it to.

The G Power unit is top class and costs about 50k Euro

Really?

One of the main benifits of a flywheel driven supercharger over an exhaust driven forced induction turbo system is the absence of any lag, and therefore keeping a very naturally aspirated feel and delivery. The engine should just feel a lot bigger than the true capacity.

Whilst some of the lovely M induction noise might change, I fail to understand where the "crisp power" has gone.

G-power have bought out, or at least become very close with ASA, who are the people who make Alpina's superchargers.

Superchargers and M BMW units can be a match made in heaven.

Throttle response is not really an issue (unlike Turbocharged engines) as it's mechanical forced induction and responds in a largely linear fashion.

As said, there are some mega supercharged E46 M3 and CSL cars around, esp in the States.

That guy`s using over 30% as a drivetrain loss to calculate his 600 HP. Drivetrain losses will be 15-17% for a manual BMW, Dyno Dynamics or not. Meaning that car`s probably running at 525-550 HP and in reality, I bet its no quicker than an E60 M5.

I have seen clips of it destroying an m5.
The article in BMW magazine claim its Murcealago type brutality....
