Here is my dyno graph with STD correction and smoothing of 4. Ambient temp was 71 Fahrenheit with humidity around the 40% range:







This was with a stock bottom end on 25 PSI of boost on E85 fuel. My 870cc injectors were at 100% duty cycle and I'm sure the walbro 255 was nearing its limit also...

I tried uploading a larger image from my photobucket but the forum website won't let me do it.



Here is a link to the image instead:

I didn't build this one, I bought it from a fiend that had it under a tree for about 8 months after he bought and had it tuned.



I have almost all the information, any questions just ask.

What fuel pump and feed line size? Walbro 255 the lines are bigger but do not know the exact size.



Stock cams? Yes



Stock head? Yes



What size throttle body? 90mm (I think its to big, I plan to test with a smaller one)



Is that a custom made intake plenum? Yes, a ebay intake manifold for an Mitsubishi Evo (I have a AIRRAM that will test also)



What ECU? SDS EFI EM-4 (www.sdsefi.com) and Water/Meth injection system (www.alcoholinjectionsystems.com)
