Default Stock Block limits

In my country, I am the first one to install an APS TT kit with tall boy, 3.5"aps test pipes, 3" aps pipes, extra oil coller, UTec computer, JWT Clutch and flywheel, water/methanol injection, ...
Nobody won't believe that I am going to make +- 430Wheelhp. They say the stock block can't handle that power, the gearbox is to weak for those power levels. The maximum amount of power is 400hp on the block according to them. Can you guys give me some dyno sheets and good arguments to prove I am right? My car is almost ready. Tomorrow it's going on the dyno. I'll post pics and movies

Thx

I blew my motor up @ 410whp! Good luck. I hope yours holds together better than mine did.

Although some people will say that 450 whp is the limit I personally wouldnt exceed 430whp on stock block. keep your tourqe below 400.

P.S, your exhaust setup is going to be freaking loud. I have it and love it so far!

You should have absoultely no problem making 430+whp on the stock motor with that setup. I had just the APS TT kit, and 2.5in exhaust and made 430whp, 410wtq on my first 9psi tune.

As for how much the stock motor can take...check this thread out...and they haven't even popped it yet...

Nobody knows the limit, too many variables. With a stock redline, Id say mid 400's no problem now a days.

400-450whp (depending on the dyno) for maximum chances of good reliability.
