Stock Bottom End Dyno#s For LT1 N/A 93 Octane and on E85
I dynoed my car Saturday @ Pro Dyno Tech in Crawfordsville, Indiana.. The car is an UNTOUCHED from the factory stock bottom end. I have LPE ported heads , Joe Overton cam and Eric Bradby did Intake porting and portmatched everything to the intake. The car also has all the supporting mods for this setup. The car has 63,000 miles on the odo. The car is also a 6-speed with a strange 12bolt. The last time i was @ pro Dyno Tech the car made N/A 416rwhp and 399rwtq but later discovered the car was running 110-120percent duty cycle on the 30# injectors.. I put 42# injectors in and retuned the car with great results.. The car made 442.1rwhp@6300rpm and 405rwtq@4900rpm. Then we switched to E85 and the car made 457.8rwhp@6100rpm and 421.0rwtq@4800rpm.. I am not sure what the dyno record is for a stock bottom end LT1 N/A is but i have to be close.. I will have track times soon.. The car increased across the board on the E85 not just in one certain area. To say the least i am happy..

It burns more like alky
Congrats with it.......
Call Eric and let him know....I'm sure he would be glad to hear what you've done.
edit: I guess you talked to him allready

yeah thats what i always thought too, i was pretty sure something like less power and worse fuel economy, and more expensive
guess i was wrong

E85 consumes more fuel in flex fuel type vehicles because of its lower stoichiometric fuel ratio and lower heating value. So in order to save money a

. at least that is what i am reading

Although proponents of E85 claim significant environmental benefits, research is showing that the growing and harvesting of corn in the US for use in E85 fuel is most likely damaging the environment and contributing to global warming.

yeah i really dont know, at all. i am just going by what i have read tonight only, this is new to me.
going by that quote alone i would assume that if he is making more power on this it is because the gas he is running does not have a high enough octain reading

Use of E-85 in an engine designed specifically for gasoline would result in a loss of the potential efficiency that it is possible to gain with this fuel.

ok, now that kinda makes sense to me, you advance the timing because the fuel can handle it due to higher octain... and that makes more power.

Thanks for all the kind words. I spoke with Eric Bradby and he was happy just like me.. I have seen alot bigger gains than my car on E85. I have seen 100rwhp gains on blown cars over race gas and 93 octane. My car was tuned on 93 octane and peak power was made at 6300 rpm with a 12.50 air fuel ratio. Check out PRO DYNO TECH.com and go under the E85 section. I may not leave the car on E85 forever but i will say this the throttle response is alot smoother.
