I’ll post time slips tonight on the split

I would like to see the reaction times as you were staged somewhat shallow in the video.

Making good power on the back half [over 24 mph] but not putting it down in the front half. you are down approx 7 mph in the 8th. Comes back to the converter.IMO. What does it stall at 0 boost.
What exhaust housing on the car?

The numbers look good to me. The 60' is about .9 sec slow from perfectly fine. I do not trust 60' numbers until I see a 0.0x RT after a very shallow stage.

The car runs 'clean'. No antics, no apparent counter steer, pulls from start to the stripe. For a heavyweight street/strip G-body, I like it.

JMO.

Tim,


I have found that unless I get the boost in the upper teens low 20’s, I don’t see anything less than a 1.6 short time. I have a stock stroke .030 over 109. I stage at 35-3600 with the flash up to 4200.  Full boost usually comes in within .4 to .6 after the launch. The 1-2 gears can usually get away with a bit more timing and a leaner AFR. If you can get a log that would help folks make suggestions. Good luck and stay safe

I’ll try again to post the log I’m not the sharpest knife. 35 to 36 not happening after adding timing I could before adding timing.
Think I flash at 4500? That’s were it falls to after every shift. Is that flash?

No, flash is the rpm that you hit as soon as you take your foot off the brake and the car moves about a foot or two.

If you can post a long, we will tell you

A lot of broken parts does not make you a racer; it makes you a slow learner.

this is the right one
the first was no alky.I made a big booboo testing the Alky pump first thing and forgot to plug in the map.
it did answer a question I had about being so rich just before letting off the brake,it was nice and lean and same 60 foot time.and did not respond any different before KR
