Thought I would share my time with everyone. I got to run it one time down because of rain. Got an 11.991@122.07mph with a horrible 2.025 sixty foot.

sixty 2.025
1/8 7.945
mph 95.32
1/4 11.991
mph 122.07

I know its got more in it, just need to get a better burn out so it will hook more. This was at Bristol Dragway. The trach prep is horrible and its not a fast track at all. I used 275/40/17 MT ET Street Radials with about 13psi in them. Any input on getting a better launch other than warmer tires would be great

 

Nice trap, what are your mods besides the greddy TT?

How were you launching, hard to give launching tips without knowing your current technique hehe. Congrats on eeking into the 11s.

 

Ill have to get my list of mods up later, but the motor was built at Forged Performance and made 541whp @15psi on the DD Dyno. I cant use my e-brake right now to help me launch, cause the cable is so loose I have to pull it all the way up just for it to tighten and hold the car. I launch at about 5000rpms. I just try to ease it out until I feel it start to hook and then lay into it. It hooks for a split second then spins then bogs for a sec then picks its *** up and goes. I Really just need alot more seat time than anything

 

Good run but with that much power your trap seems a little weak. What elevation is the track?

 

It sounds like your letting the rpm's drop below 5000 rpm's after the initial launch. Letting off the clutch and flooring the gas should be one quick motion. If this causes you to spin, then you need to solve your tire/track prep issues.

I sometimes launch the way you describe because I'm still not as consistent as I'd like to be and during those launches I pull about a 2.0-1.9 60'.

When I stick it the way I described to you, I hit 1.6X 60'.

Now, you do have a lot more power than me so there could be some variances in technique but the principles are the same.

To reiderate, if you floor the gas and let off after the innitial launch(feathering the gas), you'll never achieve the 60' times your looking for.

 

I felt it was a little weak too. The elevation is 1475ft. Couple people told me if I can get a better 60, then my mph will up 2 or 3 more mph. I still think it should be higher though

 

Actually, as my 60' times get lower, so do my traps.

 

It is one motion for me, im not very cgood at explaining that though . But it does just spin pretty much, then when it starts to spin I let off to get out of it, then it bogs down and i go from there.

 

As my 60ft's have gotten lower my traps have gone up. Diff circumstances for everybody. OP-that trap is on the LOW side for that power and 60ft....

 

I always thought that too, but ill have to see as I go. I feel with my hp I should be around 125mph

 

You have to solve the traction issues then. I sound like the initial launch is good but your track and/or tires are not cooperating.

My old Hoosier 245/60/15 DR's which are good for n/a or low boost just couldn't hold 420lbs of trq at a 5200 rpm launch. My best 60' with those was 1.77 so I got a set of 275/60/15 Mickey ET street radials and they got me down to 1.65.

Here's what I'm running!

Well, when i say lower its maybe a few tenths. Not really any significant movement. My traps are lower than most with similar setups because I'm too chicken to lean it out some more up top. On 109 octane I'm reading 10.7 a/f at 6500 and up and thats where I'm at through the traps. I'd actually feel comfortable around 11.5 or so.

Maybe we'll get out one more time with a leaner a/f before the Turbonetics goes in... Maybe!

 

i was going to say congrats cause i thought it was a stock motor...



nice to see people racing though, very cool....


keep up the good work though and get that trap speed up and times down

 

+1 thats a bit low for that HP?

 

He said it himself he needs seat time. He should be very high 120's if not 130mph in ideal conditions...but thats many many runs away still.

 

Tires, tires, tires...
The 17's aren't doing you any good. The sidewall is so short/stiff that there isn't any give. Going to a taller sidewall tire in a 15" or even 16" flavor will help TONS.
Congrats on the 11.9 pass though. Great to hear guys going out there and enjoying the cars they built!!

 

i was thinking 130 as well

 

While you're definitely right that more sidewall is better than less, his poor 60' time can't be blamed on his tires. There are guys pulling 1.6s and low 1.7s on 18" 35 profile BFG DRs on this board in 6MT Zs. I know guys who pull 1.4s and 1.5s on the exact same tire and size that the original poster has (Terminator Cobras and LS1s). Looking at your sig I suspect that you probably know some as well.

I'd venture to say that practice (i.e. more than one single run lol) is going to go much further to help his times than going and changing his tires will. Once he's down in the 1.6s and can't pull any better 60' times, then it might be time to change the tires... until then, more seat time is what he needs, not different tires.

 

Sorry, but a better tire will net you a better 60'. Guys that are pulling those 1.6-1.7 60's are selling themselves short when they could be pulling atleast 1.5-1.6 60's with the correct tire. The absolute best 60' I could cut on 255/50/16 drag radial was a 1.48. I went to an ET Street bias ply and went 1.36 with the tire being the only change. Seat time is required, but starting with the right equipment will help you in the long run. Remember, every .1 from the 60' will net you roughly .15 in the 1/4 mile.

I think tires will help him, but more seat time will definitely help more it seems! Sounds like your launch isnt that smooth. You need to slip out the clutch a little slower/smoother, and nail the gas.
