I don't know enough to say for sure, but from everything I've read, there is no way! I'm sure someone else will chime in.

Spoke to the guy at SPI Performance in Oakville Ont...He told me
that 425-425 RWHP will be obtainable...I'll keep in touch with you
guys to let you know...

That's funny!

Alot depends on the dyno, but the average ive seem is:

All the bolt ons and an LS3 with be close to about 390-395ish.

All the bolt ons and L99 will be about 380-385ish

most LS3 are getting over 400 WHP with the bolt ons, in fact i have never seen a LS3 on the forums with CAI, headers and tune that hasn't gotten over 400 WHP

This is true... and an L99 is in the 355 - 370 range SAE

its possible if you add lightweight flywheel, aluminum driveshaft, intake manifold, TB, underdrive pulley. boltons are not limited to just exhaust and intake + tune. boltons to me means everything you could do without going FI or going into the engine. FWIW

That would be on an LS3 M6. Lots of guys see 410 - 415 rwhp range with basic bolt ons with the LS3.

The L99 A6 is down around 360 - 370 rwhp or so with bolt ons.

But there's bound to be a crazy dyno or two that might produce 400 rwhp with basic bolt ons. But that car won't be any faster than a 360 rwhp L99.

On most dynos, L99s start out around 320 - 330 rwhp. So to obtain 425 rwhp an
L99 would need to make around 100 rwhp from just bolt ons.

Is this considered a bolt on? I hope to make the 400 mark with these...
