280 whp is the limit if driven hard in CVT mode (not using the paddles/bump shift). I'm sure I don't need to point out that 160 hp at the crank is nowhere near 280 at the wheels, especially with a CVT in the mix. Any engineer worth his salt wouldn't use a transmission if it truly couldn't handle more than 20 hp more than the engine it was mated to. 280 whp is more believable because that's roughly double what a stock engine will put down.

Cams, a tune, and other bolt ons will reduce the life of the transmission if you drive hard and don't take care of it. Of course, driving like a tool and not doing any maintenance will destroy it, even with a stock engine. Change the fluid regularly and don't race at every stop light and you should be fine for years. If you're really worried about it and/or you live in a hot climate, get a bigger trans cooler.

BTW just to clarify the guy that made 386 at 24 psi the same guy that is now running 18 psi his engine is sleeve thats how he is able to handle and mantain that much boost.

Evo x don't have that problem since the are semi-close = reinforce around the cylinders which means they can handle more boost and not put too much stress to the pistons movement and cylinder walls etc...

sleeves are close to 600 i may get them next month when im ready to pull the engine and build it

My cobra has a 5.4 l aluminum block from a gt supercar thats resleeved to 94 mm making it 358 ci. I can build the engine.myself id send.the block out for the work as well as having the crank turned. Thank you though.

now running all motor im not sure how the CVT will handle that, i dont know enough about how the tranny works to know if the issue is boost specifically or just the power period. i have a feeling its the boost thats the problem, and not necessarily the power
