Analyze my time slip please?
 

Heres a Time slip I got. My car was wheel hopping like mad on the launch, and I always had to let up on the gas in 2nd because the tires would loose traction and I would start to go sideways. MY tires are some no name Z-rated ones.

Reaction: .141
60ft: 2.339
660ft: 8.953
ET: 13.438
MPH: 110.889

What do you guys think my car is capable off if I eliminated the wheel hop and got some half way decent tires?

Mods are: Intake, DP, MP w/muffler, CB, G-force ECU.

If I had raced on my 18s with some decent tires. What do you think I would have run? My 18s are about 22 lbs each.

Thanks for any info :D

Oh yeah, I was running 11-12 pounds boost on 1/4 tank of 93 octane.

not bad high to mid 12 second car there

Your 60' is where your problem lies. The 18"s aren't going to help you much, I'd suggest some nitto 555R drag radials on your stock 16"s. 245/45/16 should work, bring down the tire pressure a bit too. Launch from 5500-6000 RPM and slip out the clutch to the point that it just starts to go and let it fly. See how that works.

How much do you think the 18s would have slowed me down?

Trying to figure out if its worth the effort and money to buy drag radials for my stocks as well as having good tires on my 18s and swap out wheels when I goto the track. I dont' go that often, and when I do go its normally for bragging rights. :D

Well the 18"s weigh a lot, and on top of that being that they are 18" in diameter, all the weight is further from the center than the stock wheels. It's hard to explain but it's got to do with rotational mass. It doesn't slow you down THAT much, but it does a bit. The biggest difference is the lack of meat. On an 18" tire you have little to no room for sidewall flex, this is critical for good grip in drag-racing. If you don't drag race much, I wouldn't worry about it, but for the few times you do, if you want to put down some impressive times it would certainly help.

Be careful with that. I always have over half a tank when I'm running down the strip. 1/4 of a tank can turn into a near empty tank before you know it :)

is that reaction time right?

Prolly a redlight.

A few things.....atleast 1/2 tank of gas. Forget the Nitto's, they suck. Been there done that. BFG just came out with a 18" drag radial. All the Supra guys are running them with great results. Get yourself a set. When at the track drop the air pressure to 15lbs of air, nice burnout and ride the clutch a bit launching at 5500-6000. You'll atleast take 1/2 second off your time. Every tenth off your 60' is worth 2 tenths off your 1/4 time.

yeah thats right. I didn't redlight. .000 is a perfect reaction.

Thanks for the info about the gas level. I never even thought of that.

Don't know where you got your information, but your wrong. A sportsman tree perfect R/T is .500
A pro tree is a .400

:werd:

mid to high 12s

Re: Re: Re: Re: Analyze my time slip please?
 

Many tracks are like this, while on the slip it says .141, it's actually .641. They use .500 as the point for .000. If it's under .500, redlight, then it's -.xxx

see, I'm not crazy :D

I am not a pro racer nor have I ran as quick as you, (13.8 @ 102) but I have learned that 60 footers is where it's all at if you make consistent power. I have dropped 5-8 tenths off my 60' footers by learning the ropes from better drivers. I am more than happy to share the wealth.
