Thx for the replies I dont have any lower boost graphs, this setup is a compound boost setup the twins feeding the stock roots blower so the total boost is 22psi when the turbos are pushing 12-13psi.

Can someone give me some feedback on the attached dyno graph I am curious why the poer seems to lay over like it does? setup: 2003 cobra compound bost setup twin billet 6765 .96a/r turbos Fast XFI/XIM LSCoils 160lb injectors E85 and Alky Control Dual nozzle turbos are making 13psi TH400 with...

What happend to the second chute :)

I have the GM sensor installed with the XFI. The car wsa originally tuned on E85 when I switch to 93 octane I can see the Energy Constant change however the tune is REALLY rich which makes this solution pointless. I think the thumb wheel is a better option and just create 2 tunes.

Ok that sounds good if you can pass along any info that you guys get that would be great.

Chris do you agree on what I said above?

Thanks according to this data a tripple intank setup with -6 lines from each pump to a y block to a -10 to the rails should not have an issue supporting 1200rwhp on e85 at 80-85 psi? Even looking at a tripple intank setup at 13.5 the volume vs pressure looks better than the Weldon 2435A race pump.

I agree according to this data this pump is a BEAST!

Chris do you guys have flow data at 17v?

Does anyone have a rough guess at what 700 lbs/hr of fuel on a V8 running E85 equates to fwhp? Thx

Cal, thx for the help. -Corey

No, the reason I noticed is I had the car running in my driveway and noticed that it started running rough and got my laptop and started data logging and noticed the issue. It cleared up a few minutes later and the FE constant was correct. I emailed you the logs good and bad.

Cal, a majority of the time it seems to be correct. When the reading is off the a/f is all of the place and car surges hunts the A/F is all over the place. Jeff mentioned to me that when he had the car on the dyno he noticed that the FE constant was constantly changing in the log as well.

I am noticing a difference between my main dash and my logging dash. For instance my main dash reads .676 (E85) via the flex fuel sensor for the fuel energy constant, however the logging dash reads .1xx for the same value at the same time. Has anyone else seen a similar thing. I contacted...

Thx I tested the TB yesturday without any tuning and was able to make 20psi on the brake.
