I don't think these numbers are unrealistic.
I don't either. Stage 4 will give you well over 550 at the flywheel no problem.

Everybody that do cars know that US rolling roads always has shown high numbers
I can't speak for anyone else's kits, as I don't know anything about them. I do know that my Stage 4 996TT trapped at 126 in the quarter mile.

I had k24 race(FVD) turbos on FVD ecu and it dynoed 477 awhp.
stock k24s with stock actators are more like 550 hp. just my opinion...
then when u start adding headers, clutch, intake plenum, airbox... etc.. u might gain another 30 to 45 rwhp... but ur cooking those turbos... the best is to get good hybrid k24s or the gt640 turbos.....
just my opinion.

You and i are going to have almost the same setup on the Gt2, im hoping for 530hp with my mods...Open exhoust, FVD box, uppgraded WG, airfilter
You will have to be more specific. Are you hoping for 530 RWHP or 530 at the crankshaft? If it's 530 RWHP, we are pretty much on the same page. My best guess would be 510 to 520 RWHP at the most.

No no not att the RWHP i was talking about FWHP

http://forums.rennlist.com/rennforum...d.php?t=291228

Here you se i ask about the same setup, not over 550 with stock camshafts...I know what i will belive..

My goal and hope is MAX 550hp at the flywheel but i think i will get only 530hp

That's great info. That means that 600hp is achievable from stock K24s.

Since 9Eleven lives here in the US, that means that he will be able to have 600hp.

As we have stated in many threads before, dynoing can be very subjective. The way that we have found to be an unbiased, callibrated measure of HP is trapspeed in the quarter mile.

Trap speed is a very good indicator of HP.... a 600 HP tt should trap around 125 mph.

What about a 600hp Gt2? Would the trap be higher?

Here's my stage 3 Graph with Remus Exhaust: http://members.dslextreme.com/users/...o/Dyno%20Runs/

I don't have headers and run my stock manifolds.

I think that upgraded wastegate actuators are a must. I had mine done at Speed Gallery.

That seems right and very attainable
