Dyno Sheet pix

[Razor]

Heres the sheet I was able to snag from last week. I'll see if I can post the corresponding logs.

The 548 was 27 PSI
The 584 is 25 PSI and 35 shot

FWIW I ran the same boost in my times down below to generate the 10.55. So the power has been upped a little..

Quest for 9's... can it happen on stock pistons and pump gas?

Wanted to add the TQ was down becuase of a delay created in applying the nitrous. You can see the curve start low then wham...all the way up. Button was hit at 20 PSI cuasing it to jump to 25 PSI.

The dyno shop needs a better printer

Joe to keep my tests normal, I have targeted 11.3.. this is the AF I have been racing at. The nitrous jetting for the meth I thought was a little large so the afr dropped down to 10.8. The next pull I dropped the jet one size and the AFR went up to 11.3--11.4 but it picked up a few degree's KR. Timing dropped to 21 and it made like 576. I would rather live on 584 no KR and a fatter tune..

When the new XFI goes on next week.. i'll be able and log the methanol pressure, nos pressure, and conrol the system a lot better than on a push button as it currently was for the tests.

10.8 is not a bad number in my experience. It's safe.

Simply Nice I think 9's aren't to far away with your tuning ability and experience in general. Keep up the good work and awesome tech support.

rasor

what kind of tires,rear suspenction do you have with those fast times your running.

 

[Razor]

I alternate between a set of 6 year old 26x10x16 slicks and my daily MT drag radials.

9 inch rear, random tech TQ arm. Stock lowers/stock oem springs/stock panard.. Denny's drive shaft.. Stock shocks up front. At Reynolds the car was raced with the factory 16x8 wheels and both front/rear sway bars attached.

I took the front sway bar off, put the old slicks on, left at 15 PSI coule weeks ago and hit a 1.44 60 foot..

Little by little.. this build is proving better than anticipated..
