That and 3lbs of boost Elite275 has my old blower and we use the same shop so it's a decent comparison of similar cars at different stages of mods.

Oh ok, I am with you now. I thought you were referring to picking up 100hp from just e85 while already being at 13psi.

My bad.

It was over 80hp going from 93 to e85. The dyno shows 1) before pulley swap on 93 2) after pulley swap 3) e85.

I have the cpr low psi system. Install wasn't too bad, getting that fitting installed on the tank was the hardest part for me. Quick tip, dont apply any sealant until after you get the 2 screws started!! I apparently installed my pump a little bit further back than i was supposed to. Joe or Justin were going to send me a little extension for my fue line (subtle reminder guys!)

Unfortunately i haven't been able to tune with the E and blower yet due to a software issue at my local shop. My car made 773rwhp on 93 pump and 3.6" pulley so we left it on 93 so i could do a 1/2 mile event. The plan now is to lower boost a bit with a 3.8" pulley and then add in the E but we're waiting for some software fixes at the shop first.

My setup is:
LT4 HPFP
LT4 Injectors
Camshaft with the 33% overdrive
Dual Nozzle meth (15gph and 5gph)
CPR Low Psi Fuel Kit

Oh man Ken you have a ton of room in that setup.

I am told by two highly respected tuners (Vengeance and Formatto) that 2.3 liter blower, lower pulley, headers, off-road xpipe, cam (with fuel lobe) and a low pressure fuel system upgrade will be able to fuel properly on straight e85 (but no Meth). I don't have the rwhp level yet because I haven't done the upgrades yet but I'm thinking it would be somewhere around 750 RWHP if I did the upgrades. They both said that a low pressure fuel system upgrade would be critical even with the simple upgrades (simple as in no porting of blower or heads).
