X2 on the EGT's!
If you are still using the narrow band O2 sensor
I Would be interested in those readings also.

I would think he would want to actually tune to the potential of E85 .. otherwise whats the point of the conversion .. I doubt he is just trying to save money on fuel costs
That's why I asked. I would switch to run the same boost and timing I was on 110 for fuel costs. I would also switch to run more boost and timing then 110 and also save on fuel costs. Just wonder what he's going to provide us. What data logging equipment etc he has

Sorry to keep you all waiting. It's been a long morning. The short answer is:
100 octane: 449.4 hp
e85: 471.6 hp
We changed from 60 lb injectors to 80s, went to a wideband 02 and of course a new chip. I have the powerlogger but I don't have the files yet, so I can't answer too many of those questions.
Oh yeah, that's with the exhaust dump open. I have stock exhaust and it sucks 60 hp off the e85 setup!!!
Price of fuel before: $8/gal
Price of fuel now: $2.65/gal
Can't beat that.

Here's my basic setup before the conversion that was on my member intro post:
Precision Turbo 6265
LS-1 MAF
Big Mouth cold air intake
ATR liquid to air intercooler
Walbro 340 fuel pump
60 lb. injectors
3000 rpm stall converter
Also, we did not change the boost at all between setups.

To many unknows, what chip was in the car before, what timing and boost was that chip set at? Was it a wb, sd, or regular chip, what was the air fuels.
We're both runs with the dump open, what was the temp difference between the runs,
Guess the new chip had wb tracking making the tune closer to optimum.
Etc etc etc. .

Sounds in line with what I would have figured 10% at the motor is the norm just from the fuel change alone
optimized double that ... all while less than 91 octane pump fuel ... WIN WIN
Funny you should mention the open dump .. I compared a ATR setup to a open dump .. it cost me 13 mph in 1/4 .. lesson learned
that's what I am saying correct... I am basing this on about 50 different conversions with dyno pulls... it usually yields 10% at the motor just from the fuel change .. it can be more
68 rwhp is the most ive seen .. JUST from the conversion alone ... same boost.. same timing.. same EXACT setup.. just fuel change.
