Going to the track tonite

[gahanna-6.4]

Ok ladies. I'm headed out to Pacemakers Dragway this evening (5-10pm).
Anyone else in Ohio? Track info here: Pacemakers Dragway Park

I'll be armed with a Video camera (and 2 people to help videotape), a laptop, 1.20, 1.22, and LW64TR122-4OR_Protected.LFU.

I plan to make several passes on each tune with a good video and I'll keep good notes on everything on the back of the timeslips.
Once I get back I'll get the timeslips scanned and uploaded along with the videos.

gahanna-6.4 Sounds like you'll be having a lot of fun! Wish I could be there, but al ong way from Texas. Will be interesting to see the results. Keep us posted...

I'll be interested to see how much smoke those tunes produce. I for one, would be very happy if they were relatively smokeless.

If you set your shifts right. I bet 1.22 will give you the fastest time.

[gahanna-6.4]

Ok just back. 1.22 release tune is slower in the 1/8th than the R&D tune that I have.
Tire spin even in 4wheel drive is absurd - spins 30ft. Tried 2 wheel drive and at first and just blew them up in smoke.

Anyhow, I'll upload the videos of the 3 runs tomorrow morning, lotsa smoke! The track starter even asked me NOT to run in the groove at the starting line because my KM2's would tear the track up LOL!

All these 1/8mi times were in 4 wheel drive still spinning ~30 ft, leaving with 10lbs boost:

1.20 - 9.80et 68mph 2.2809 60 ft
1.22 - 9.55et 70mph 2.0791 60 ft.
1.22 R&D - 9.40 72mph 2.0420 60 ft.

The defueling midrange to top end is horrible. I think with a proper tune it could pull just as hard mid and top end.

how do you get the 1.22 rd tune?

[gahanna-6.4]

Well Im quite disappointed in the fuel/power curves that have been made for these trucks. Its painfully obvious that they were tuned on a static wheel dyno and not under real driving conditions. The 1.22 power is all down low and quickly runs out once the mass is moving. The power band is far from consistent, I don't care what the dyno sheets show - they do not equate to real life driving. Yes, making 40 lbs of boost right off of idle is neat for smoke shows and impressing your friends but its worthless as Paris Hilton for either sled pulling or drag racing - not to mention its far far far from user friendly driving around on the street.

I've been drag racing for 30 yrs in either SuperGas, SuperComp or ProStreet. I've never driven a more inconsistent vehicle. I made 3 passes with each tune and struggled to keep the truck within .500's of a second in consistency with each run. Horrible.

What we need is a good consistent tune that makes decent, consistent reliable power across the spectrum, not just on the bottom or top end. I realize that these trucks aren't designed for drag racing but as inconsistent as the power is they would be worthless for pulling sleds too.

I would love to get my hands on the ability to tune these things at the track under real life conditions. The fuel injection units we run on our race cars nowadays allows us to datalog so many things and change them on the fly, I just wish F.A.S.T or SniperTuning would come out with something for these trucks so we can create some really nice setups whether its sled pulling or drag racing.
