GPower SKIII

[mikewads]

Did a few Google searches tonight after I was told it was a built motor and was running 13psi. Look what I came across:

G-POWER M3 Supercharger system SK III - plus 230 hp
Basis: M3 V8, 420 hp (309 kW) increased to 650 hp (448 kW)/650 Nm consisting of:

Forced induction: ASA T1-725 supercharger including overrunning clutch ASA K07; supercharger lubrication through bypass from motor oil circuit; ultra stiff CNC shaped supercharger bracket system made from aluminum including an extended support-aggregate belt-drive for the supercharger’s drive; pneumatic controlled, engine load related boost control; flow optimized, large volumetric fresh air intake, including 8 integral resonance induction pipes made from light polyamide, ensuring an optimal throttle response and a perfect torque curve racing air filter. Boost level approx. 13 psi rel.

Intercooling: Large volumetric intercooler system using flow optimized boost pipes made from casted aluminum and a large, high capacity air to air intercooler made from aluminum in the car's front.

Engine modification: 8 fuel injectors with enlarged mass flow; 8 weight optimized forged pistons for a reduced compression ratio of 10:1 supplied from our technological partner Mahle, 8 balanced, weight optimized
and reinforced con-rods
Exhaust system: G-POWER complete exhaust system SPEEDFLOW, optimized exhaust conduction
through dynamic pressure reduced exhaust system including first catalysts replacement pipes, two racing
catalysts, intermediate muffler and G-POWER full stainless-steel sport rear silencer with 4 x 83 mm tailpipes
featuring the M-design look.

Electronics: Custom made software for the standard BMW engine and DKG- transmission electronic control
unit (BMW OBD stays completely untouched), enabling an unlimited top speed of max. 320 km/h, according
to the capacity of the tires.

shit , thats fast when you really thing about it ..........

nice find mike. so it is a built motor?

most likely

[biglare]

That explains a lot, finally!

I am thinking that a fully built motor should put more power down and even better numbers, but maybe they are still tuning.

I think this:
8 weight optimized forged pistons for a reduced compression ratio of 10:1 supplied from our technological partner Mahle, 8 balanced, weight optimized

qualifies as "built."

I know the day we went out there they had stayed up literally all night finishing the tune. They finished at 10AM and we got there a few hours later. I have no doubts that more power is waiting to be had with more tuning.

wonder what else they did to the engine besides pistons and rods

[quality_sound]

What else would it need? The crank is already forged so other than knife-edgeing it I don't see much they can do unless they want to get REAL hardcore and bore and sleeve it, assuming there's enough block material to even do that.

I would have to say, that if you going to that extreme, why not bore and stroke at the same time to 4,6l, and lower compression at the same time?

With low comp you can go to the 13 psi boost pressure, however it would probably be better to go less like 10 psi, with the bigger capacity and make similar power

[quality_sound]

That's assuming there's enough block material to bore it that much. Stroking would be a good idea though.
