I've HEARD that about E85 too but to be fair, I've personally never seen it be a problem. Then again maybe I've never seen a car sit all winter that runs it. I suppose you could flush the tank if you stow it all winter, otherwise take it for the occasional drive every few months. I would bet you could see 25psi all day long in the stock block but like I said, better to try to shoot for lower boost and more power, it means a more efficient setup and nobody would mind that of course.

 

X2, certainly 500 without problems so long as the tune is proper.

 

I'm putting down 467whp on 14psi. Ptuning gt3582r

 

T1 racing highly recommends you do not store your car with the 85 in the tank over the winter. I started a thread last winter regarding that issue. My advice to you if you cannot run your car every few weeks in the winter is to drain the tank of the 85.

It's simply disconnecting the return line
and emptying into a 5 gallon container with the car running. Once it is empty, and you know it will be empty when you see air bubbles coming out of the return line. Fill the car with 93 octane and then load your 93 octane map. Turn the ignition on and off to get 93 octane into the lines. Then start car up on 93 octane running around a little bit and then park it for the winter.

 

Thanks for the info. Yes this is what my tuner said to do

 

I agree. It's definitely not safe. I wouldn't go over 14psi on a stock block. Anything over that, e85 should be used. I say e85 because of the better cost and availability depending on location.

 

I will tell my friend that she,s been driving a time bomb for the last 2 years.
