Knock limit turned off?

Yes.

You should be 133+ with a 3.625. Still have the Whipple tune?

Have you talked to Whipple about it yet?

Actually the 128 was on the 3.500
With the 3.625 trap was 123
Yes still on Whipple tune

Not yet.
I was watting for the revised tune (hopping that the higher shift points would solve the issue)

Well there's an easy fix to that problem.

I Know!

But still the low trap (compare to others running on Whipple tune), seems strange.

I hope everything is OK.

Summary

3.625 with 93 oct on Whipple tune
11.55@ 123 with 1.72- 60’

3.500 with 104 oct on Whipple tune
11.09@ 128 with 1.64 - 60’

Last Thursday

3.375 with 104 oct on PBD tune
10.65 @ 132 with 1.63 - 60’

Consistently 0.5-0.7 slower than what should be

This is on Salinas Speedway in Puerto Rico

I’m looking for advise to reach 9’s. I’m running out of pulleys for my 6 rib 72 lbs injector setup

Loking at

Springs, Vikings, axles shafts and a 2C for the 60’s

Would E85 and Fore fuel system get it done?

Log for the time slip attached.
In case someone can see anything abnormal in there.

The MPH is right where it should be for the ET but you definitely should be going quite a bit faster. You should be touching the 9s on the 3.5. Are you sure PBD has everything dialed in on the tune? I'll look at the log and compare to one of mine.

According to Rob yes. The car was good but I was definitely expecting very low 10’s to high 9’ on a 3.375 and 104 gas
This was a tune revision that I recieved at the track.
The first pass was a 10.7

0 knock. 18 degress ( I think is kind of low)

So one thing I noticed is the timing is quite low. It's probably an issue of the fuel. I would ask about the timing. You should be able to hit 24 with the right fuel. I doubt the will make up all the difference but there's definitely more power in it.

I would ask him about MS109. That's what I run and I'm around 23-24 degrees on my 3.2 setup.

I just noticed you don't have the 2C. They way I read it is that you did. That's all the difference there. Add that with better fuel and timing and BAM!. I picked up 4 tenths with the converter alone.
