Sprayed the LLY again....

You will get there someday Jason! And maybe put a smile on your kids face by them riding with you on your first pass!

Reading thru someone said they are launching by rpm, sound of the turbo. With Danvilles 72 what are you guys leaving the line at? Rpm/boost? Anything higher than 10 psi I spin all four tires. I have cal trac's and rancho 9k out back and QA1 double adjustable up front set on the stiffest setting.

Do you hammer the throttle right after letting off the brake?

Yes

Is that a trick question? Hell yes I do!! Lol

Glad you brought that up... I think many would be surprised to know logs show a lot of guys are not at 100% throttle position! I have a theory that the initial effect of the launch forcing you back in your seat may influence your foots hold on that accelerator. Has happened to myself as well as a few guys local to me whose trucks I've logged.

PIN IT TO WIN IT BOYS!

Depending on the track prep and temp, I can leave at 17-20psi Anything more and I spin. On the street I have launched at 20psi and pushed through the brakes, hopped and then hooked. I'm on 305/50/20 Nitto 420s with my tbolts out and pass cranked 2 times.

I may not be leaving hard enough?

What are you leaving at boost wise?

 

[DetailsUnlimited]

10 but 20 comes on very fast. I will be going back to my S420's next TNT.

Yea I know what you mean. I prefer psi because a difference of 50 rpm's could mean 10 more psi and pushing through my brakes. It's a slow start to 7 then at 13 it comes alive haha

You sure your tuning is ok?

 

[Cknight199]

You sure your tuning is ok?

Yes without a doubt. It's at high elevation, stock does the same thing.

After turning rotors and new brakes and stainless steal brake lines. Holding the truck is not hard now.

What converter do you have?

 

[DetailsUnlimited]

Have you checked for boost leaks if it's slow to get 7 psi of boost?

 

[DetailsUnlimited]

Precision ML converter. Around 2300 stall

Yea I have leaks around my egr nothing too major though, I tested to 60 psi and it was barely audible.

And it's not exactly "slow" maybe 2-3 seconds, then it's responsive as hell.

 

[MarkBroviak]

I leave anywhere from 20-40psi depending on how hard I'm to go. I left at 35psi when I ran my 10.96 pass at TS this spring.

 

[Cknight199]

You guys do know I carry Rancho right?
