Better 60' + trap speed. With some serious rubber times would be night and day.

 

How used are the tire u are racing on?

 

my bad, I thought u were kidding cause I posted I ran 14.0 already at the beginning of the thread with the same tires, I think i have liek 20k miles on them.

 

I recommended that you do NOT use the two step. Also are you using a boost controller? Does not seem normal to spike that high (14) and then drooping all the way down to 9. Could be the GReddy Wastegate. Did your tuner give any insight on that?

 

Yeah i have a turbosmart manual boost controller that causes a little boost spike but its supposed to be at 14 psi, but the greddy wastegate is only holding 9-10psi. He recommended me getting a GT28 Wastegate actuator to try and hold more boost cause the greddy 18g wastegate is known to not hold much boost. I'm gonna try running with 2 step and for a couple passes then non 2 step as well

 

So you are running 14lb of boost and pump gas correct? Hmmm...I guess depends on the tracks prep, but I'm predicting that you are going to blow the tires off with All Seasons. But I'm in to see the time to see how close I am. Didn't realize you were on 14lbs of boost for the run, so I'm going to change it to

15.0 @ 117-112mph.

I have a track day tomorrow too, but full Road Course not drag.

 

running on the all seasons will be fail. I suggest not to use 2 step and try not to roast the tires. Low 14's with a high trap speed probably. Get a set of radials and you should be low 13's

 

i still stand 13.6 if you dont use 2step

 

watching...

 

14.6@111


2.3 60ft

8.8 1/8th mile

 

im gonna say 13.9 @ 104

Ill be hitting the track up Sunday myself, lets compare Greddy kit times...

 

I say 13.8 lol if tires are good if not 14.0!! Trap will be around 106-110. Just my guess.
I has made 13.8 on 326whp spining so maybe if you get better traction around there. Lol and got 13.6 on 370whp sonething like that. Traction I'd your biggest enemy!

 

What an exhausting night, we're gonna try to datalog my car tomorrow to make sure the tune is dialed in, traction was DEFINITELY hard to control, hopefully LSD installed soon.. but for the results!!!!

Best run

R/T: .631
60: 2.528
330: .000
1/8: 9.800
MPH: 78.43
1000: .000
1/4: 14.679
MPH: 102.34

Not as good as I've ran in the past but from here on out there's just lots of learning I'm gonna have to do. Best time was with 2-step, but I also ran a 14.8 w/o 2 step

 

I think I win for closest ET guess....heheee. I was expecting a LOT higher trap speed though. No way 14lbs of boost should be trapping at only 102mph. I would expect a 102 trap from a tC that was on 6psi of boost.

 

should have datalog with each run, that a very good data you can tweak even study your run.. you sure have some things to work on

 

I am sorry but two step regardless if you are running slicks or street tires will help in any situation when used correctly! Obviously LSD would make it a lot better and slicks would be ideal but not required.

 

I called 14.6 lol

 

bummer dodaddy.

 

Your 60ft time needs major improving. If you can get that down to a mere 2.1 (which isn't great either) you'll shave a lot of time off.

I have to agree with Trav on the trap. Something isn't right there. Did you miss a shift or were you shifting slowly?

 

Need a better tune!!!! how was the spining? and 2 step regardless of used right or not on street tires your gonna spin like a ****! unless your running some serious street tires like 100 threadwear.
