Look at my slip. Help me please

3v non intercooled stock pulley Paxton. LCA. Sway bar delete. Everything else is stock. 5-speed car. I'm left lane

Second slip left lane

 

[stkjock]

Tire?

 

[kwadkins]

26inch slick

 

[irishpwr46]

1.9 60's on a slick. youre having issues with traction for one

 

[Townson]

Tire pressure? Launch rpm? Slipping or dumping the clutch? Suspension setup?

Also, what gears you running?

 

[kwadkins]

15psi. Leaving at 4.5k dumping the clutch. Stock 3.55 gears. How's the MPH look?

 

[stkjock]

mph is good for 11.7-11.8 with a good 60'

Is it spinning, bogging?

What's your burnout procedure?

How old are the tires? What tire exactly

 

[Townson]

Mph indicates you're spinning. That's how I see it anyway. We need more details bruh. Drag radials or bias ply tires?

 

[kwadkins]

Mickey Thompson et street. Not sure on age because I bought them used. I just roll into water box and spin them in 1first for maybe 5-6 second. Car kinda feels like it's bogging. I was comparing other people's short times and even with a better 60 I would still be a half second slower in the 330 foot ??

 

[irishpwr46]

definitely not getting them warm enough. you want to do a second gear burnout at around 50 - 60 mph for close to 10 seconds and get a good white smoke going. that "smoke" is actually steam burning off so that will tell you about how hot the tires are getting

 

[kwadkins]

Okay. What RPM do people usually leave at?

 

[Townson]

You're doing a burnout in the water? That's no bueno.

Here's what I do: Go around the water, put the car in reverse and back into the water. Spin the tires over just a little. Pull up a few feet in front of the water box and rev to 4 or 5k, dump the clutch and hold the brake. I don't do that long of a burnout. Maybe 3-4 seconds, but you may need to do it longer since you're making more power.

If they're et street radials then 15 psi is way too low. At the least you should try 18 lbs. hot.

If you're bogging at 4500, then try 5000 and from then on bump it up by 200 rpm's until you get it to spin a little. Then back off a little.

/\ this, but you should only need 4-5 seconds IMO at 55ish MPH

Okay. What RPM do people usually leave at?

I left at 5000 with a radial. You should leave higher with a bias.

15 is to low.

You can check the age on the sidewall. There is a four digit code, month and year of production.

 

[lindertw]

Okay. What RPM do people usually leave at?

6500rpm off the limiter; with the right suspension/tires (and good air, great track prep) you can get away with those shenanigans

 

[NickD87]

still dont know what tire your running
first it was slick then et street.. bias, radia, size needed
You also prob want more gear with the paxton

 

[kwadkins]

26 inch ET bias. I'm sorry I said slick due to the tire being very close IMO to a slick. What about 4.10 gears

 

[stkjock]

4.10 and 26" tire are a good combo for a centri blower.

Are you power shifting?

My '07 GT was very similar to your car. Vortech V2 non-intercooled, but an automatic. I ran similar trap speeds, but ran 11.80's with it. Only had a few mods on that car: 4.10 gears, 4800 rpm stall converter, 26" M&H Racemaster D/R's, and custom dyno tuning. The steep gears and high rpm launch really helped get the centrifugal blower into the boost quicker to get the car into the 11's.

As others have said, your trap speed indicates a high 11 second car. Just need a harder launch to get there.

New personal best. 18psi leaving at 5500 rpm
