[QUOTE="c_mart_28, post: 11453290, member: 59405"] Well I can speak from a little bit of experience with a similar setup. I had run a 2.3 with a 2.75" upper and a 4 lb lower for about 2 years on E85. Couple thoughts: Heat soak is the biggest issue with spinning the 2.3 that hard. I had a 5 gal ice box and a bigger heat exchanger and it still needed at least an hour of cooldown between passes. Belt slip may be an issue. I didn't have a manual belt tensioner but I did have the support plate the tensioner. I saw 25 psi peak and about 21 psi by redline. I considered going the nitrous route but hadn't planned on a 100 pill. I just primarily wanted to lower IAT's for the last half of the track. I ended up just going with a bigger blower (3.3 lysholm.) I hope to make more power on less psi and have it do it all the time. That said though, 600+ (peaking at 718) ft lbs of torque at literally 2k rpm was awesome. I also think that a small shot of nitrous, if done properly, won't shorten the shortblock's life too terribly bad. [/QUOTE]
