New best 11.0 @ 126

[grandnat86]

Finally got to take the car to the track with the new ta6265 dbb turbo. It ran an 11.1 and 11.0 @ 126. The car couldn't take anything over a 2 psi launch with the 255-60-15 drag radials. The best 60 ft was a 1.7, I tried a 6 psi launch and it blew the tires off. Time to step up to some 275-60s and a big rear sway bar. Couldn't make anymore runs due to the track officials booting me for no cage.

Nice,

What was your boost and timing?

 

[grandnat86]

24 psi and 23/21 degrees of timing. I also added 5 gallons of sunoco 104 for a little added safety.

What pressure in the radials? It takes some experimenting to get the proper PSI. I know a person who got best results around 20-22lbs.

Awesome! Consider what you coulda gotten if you had some time to do the runs and tune it! What kinda tires are the ones you ran?

 

[grandnat86]

I'm currently running the mickey thompson 255-60-15 drag radials. I ran 18 psi in them for all three runs. Time to step up to the 275-60s, but i'll need a spacer to keep them from rubbing the frame.

275/60 should clear fine if you still have your stock aluminum drums. what wheels you running?

 

[grandnat86]

I'm running 15x8 summit stars, with the 255/60s I can't even fit my finger between the frame and tire. I should be good with the spacers.

What was your 330' and 1/8 mile time/mph? Nice run.

 

[grandnat86]

330'- 4.65, 1/8 mile- 7.10 @101.15

 

[king kong]

Nice pass....hmm should have known my man OTTO was part of your combo....LOL...He's the best!!!! Mayb we will meet at the shop one day...

Nice mph gain from 1/8 to 1/4.

I run the MT ET Street radial (255-60/15) at 21-22# and I can get 1.5x 60' with 5# launch off the foot brake. I went with that size because the 275 would rub on my car.

 

[pacecarta]

fyi
his 101.1 1/8 and trap 126 is typical of what it should be
typical 1/8th to 1/4 gain is ... 1/8 mph x 1.25 , for those that dont math well if 1/8mi is 100 you should expect 125 mph in the 1/4 unless theres something wrong with the tune


and FWIW 126 could've netted a 10.8 timeslip, his next time out on stickier tires should show that

NICE times!!, and congrats on your new best!!

 

[grandnat86]

Thanks, I also have to upgrade my fuel system this winter. I couldn't get the AFR below 11.5 so I had to run very conservative timing and boost.
