MAXIMUM OVERDRIVE / Re: 1/2 mile event close to Indy

Good luck, these half mile events are growing.

What's going on with you're chassis? Swingarm flex?

MAXIMUM OVERDRIVE / 1/2 mile event close to Indy
« Last post by RansomT on July 24, 2017, 10:53:40 PM »
Looks like Shift-S3ctor is going to allow motorcycles at the August 19-20 event in Marion, IN.  I do believe that if I can get my nitrous bike to drive straight during heavy acceleration, I'm going to attend.

Good to know. I think I will just buy a Woolich ECU tuning kit and I can experiment with timing, and fine tune fuel without the PC3.

You will gain a few HP just from going to ethanol from pump.  A couple of degrees of timing will also help, but ethanol doesn't like a bunch of timing because of the way it burns.  The flame front is quicker but is less explosive than gas based race fuel.   Timing with nitrous: I have found it makes just as much power with a more conservative timing curve.  2 degrees for the first 50 HP and 3 degrees there after.  e.g. 7 degrees out for 100 HP shot.  13 degrees out for 200 HP shot.

Thanks Ransom. I was expecting to gain a few NA hp advancing the ignition timing, did you not find any advantage? Do you retard with spray?

Speaking of Ethanol.  When you start tuning, you will need about 30% more fuel going from pump gas to E85.  If you use "the gas scale", AFR should be a touch richer than with pump gas.  Typically, on motor only pump gas likes 13.1-13.2 for most power while E85 likes 12.8-12.9. However, Ethanol has a bigger tuning window.  Timing is the same as gasoline.  Under nitrous, aim for a AFR (gas scale) of 11.5:1.  Bigger the shot, the richer you can go.

Hey Greg, it's good to be working on a bike again.  :fiddy:

Got the injectors back, they flow 560cc at 75psi :)

Thanks for the info Ransom, I think my moderate shot will be ok with C85, the convenience of an in-town VP provider is hard to beat.

Larry, I'd love to see a picture of the drag bike, is it a NA ZX14?

I got the brakes on last night, took a little convincing to get the Suzuki and Kawasaki parts playing together :)



Looks good Dean , wondered when we would see you back

offset pin is dependant on your cam timing , you need to check it and use if needed , i have a couple of gen 1 bikes running fine with gen 2 cams and no offset pin, and one with gen 1 cams no offset pin

Gen 2 cams need the bearings flipped to get the locating clip in the right position
