These are the latest runs on my current setup and getting more into the 10's. The car weighs approximately 3560lbs with me in it currently. Sadly I didn't get a slip on probably one of my best runs (lifted the front tires off of the ground).

 

I ran Hoosier 28" 295/50/16 dr's/Moser 9" 4.10's and a Yank 4000 stalled A4. Tires up and no spin at all on not so good prep. 98 T/A 418 ls2 4.1 stroke Gmpp ls3 heads, stock intake Fast 92 tb. 235/250 113+4, LT Moral lifters. Same weight!

 

Very Nice! What was your trap speed in the 1/4 on that run?

 

That trap speed is impressive. Get that 60' down and you got easy mid 10s. What was the DA?

 

That was my only run. It was a 1/8 mile track here in F.L. They told me to at least put on a fire jacket and to not where shorts. lol. It gets warm here in April. I'm close to done with a 426 ls3 build. I have been scratching my head on what intake to use. I bought a lsxr with medium runners but most guys here like the Holly Sniper better. I found that BTR now makes a ls3 Trinity good for 8000 rpm that fits under my hood. My roller cam is spect to rev @ 7600 rpm so I'm going to order one, Between the two intakes Ill keep the one with the best mph and or 60ft time. The other will go in my 08 Vette vert. Hopefully the Vette will get the Fast so I can switch the runners for less rpm. The Vette will get the 418 cam. Short travel Morel (BULLLET) lifters, Gmpp ported heads and a Yank too. Yank said they had the same c-6 corvette over there with one in it and ran like stock but can pull 1.5 60ft's on dr's. Paddle shift 6L80 2.56 gears! If that works I might leave the stock cam with the short travel lifters in it for maybe 10's and 30+MPG.
If you can send me any info on those Siemen Deka 80's for the computer I'll buy a set. What pump are you using? The 418 was using ls3 injectors with a 380 Walbro pump. Injectors were at 100% DS at 7200rpm 1 to 2nd shift and liked it. Yikes!

 

Appreciate it, DA was -360 to -400.

 

I'm still running a racetronix 255 with hot wire kit on 93oct. My rod modded intake manifold is holding it's own at 7k.

Check out post #10 for injector data below.

I bought the Greg Dash DVD for inj data and later found that the data is all over the internet.

 

Hey you finally got a hood on the car! Just saw one of your vids and I'm thinking man, no hood anything can go flying in there.... Nice runs though!

 

Nice runs fellow stick shift man.

 

Hell yeah, thanks man. It's been a few months with the new hood painted.

Thanks man

 

Getting that suspension dialed in will for sure net you some low 10s with that trap. she's cooking on the back side !

 

Yup I was thinking with a 1.3 60' that's 10.0 there with that 131 trap.

 

That should be around 121-125 mph in the 1/4 with an 10.9-11.0 ET

 

I think I'll need to step it up and get the double adjustable front shocks. The singles are working okay but the front moves a bit between shifts.

Yeah the 60' needs improving tremendously! Last time out I was averaging over 132mph with A/C and heavy T/A powered seats, along with my full size front tires lol

 

What kind of tires are you running on the rear?

 

Hoosier QTP 27-11.5/15 bias plys

 

Tires aren't the problem then, how does the suspension look?

 

Front:
Strange single adjustable coil overs, 300lbs springs
UMI tubular adjustable upper and lower control arms

Rear:
Comp Engineering 3 way shocks
Springs-Vogland springs in the begin runs of the vid and stockers in the end runs
Founders tubular control arms, panhardbar
UMI adjustable torque arm

 

Car is lowered too right? If so, then yeah you'll need to make adjustments to have the rear end squat better.
Maybe some tips in here can help: https://ls1tech.com/forums/drag-raci...est-60-ft.html

 

Yeah, so in the video you can see I lifted the rear up a bit when the stock springs were added to the rear. I started with a ton of anti squat and then added a lot of squat via springs and rear lca angle lol
