it can be done if tuned properly.the setup lasted about 4-5 months at mid 500s and i turned up to almost 600 and it let go soon after.motor had about 40k on it and i drove it like a i stole it.

i did a rsx-s that made 530whp on stock motor in 2006 and it is still running. how the car is driven and maintained plays a big roll

ok i got you guys.. i know afi makes a sidewinder mani, you know same same in a sense. I havent seen any real crazy numbers with a log style mani, partially due to the fact that they cant flow as well. I seen close to 400 but that was pushing it.

Will you post a picture of your dyno sheet, I'm not doubting the numbers. This is one of the setups I was looking at for my car and wanted to compare a couple of things. :up:

Yeah, sure will. I was having fuel problems when I dynoed so we didn't tune much. I picked up a bad tank of fuel on the way to get tuned and it clogged up my injectors :mad:

Here is the map, the numbers are uncorrected, tuned in the 102 degree weather @ 87% humidity as well. Weather sucked for a dynotune, lol

I know the term stock block gets thrown around loosely on the web sometimes lol. But anyway. I am fairly new to the k series stuff but I have owned a built b series that ran tens.

My question is what is the hp limit on the stock head bolts. I have the turbo stuffready to go on and I'm looking to get 450 all stock motor. Do you think I'm gonna have head lifting issues?

As long as the motor doesn't detonate, the stock headbolts should be fine.

How those stock trannies holding up?
:dance:hahhaa Best question yet. 450 on a stock motor seems ridiculous but if you said its been done i believe it.

So how about getting that whp to the wheels. How do the stock trannies hold up to the abuse of close to 500hp crashing down on them? remember that this would be hp before tranny loss. on a 450whp car that could be upwards to 550 to the crank. I'm very interested in knowing if a racing clutch, pressure plate and flywheel is enough for the tranny.

mine setup 537hp /w K20Z1 tranny is showing signs of fatigue and it has seen very little abuse. So I can safely saw 500+hp will cause failure based on usage.
