were i live E85 is 30 miles away, being that it is my DD that would not work very well. like i said i have a few friends that have made 600whp on stock Intake Mani, I have seen people make 530whp with stock COP. so if it starts to missfire ill tell my tuner to back it down a little. i am aware stock cop and stock mani will hold me back but wont kill me
and meth is the only alterive for me to use every day, it is 93oct or 93oct plus meth and thats it... ill take the chance bec i wanna go fast

Stock ported intake has gone 8.90's. Stock ignition with fresh OEM plug wires and good spark plugs will fire well over 700 whp. The big push for COP's in the beginning was mostly related to engine management systems. Stock ECU and the Haltech for example don't need a COP most of the time. Stock head is also good up to a point. You have to be making decent power to find any real gains in head porting, reshaping and smoothing the combustion chambers is a good gain as you can generally run some additional timing and leaner AFR's without knock.

I know many people who have been running wmi for a long time with no problems. Just becareful no matter what you are tuning with.

I have run meth for about 50000 mi with no issues. I used to run alot at one time as well. I also think its funny how people talk about it blowing motors when the most motors I found posted on this forum were blown on pump gas. Most of those blew cycl. #1 or #4.

Good info. What power level do you think that the porting/oversized valves become noticably benefical?

meth is scary, i've seen a few blown motors due to meth pump failing. i understand many guys might rely on a good knock sensor, but by the time the sensor hits, that motor would be long gone.
