Ok guys, I'm taking my car to the track tonight to see what she posts for 1/4 mile time.

What are your guesses I may run? I am a newbie to track racing. Only 3 runs in the last 10 years of my life. (obviously a lot of the time depends on my skills driving)

Shes is fresh off the dyno 3 weeks ago and posted 557.8 whp. Mods are as follows:

345 width tires (street tires with good tread)
6 speed, manual

*LG pro Z06 longtube headers with highflow cats
*Z06 stock exhaust
*Cam spec= 224/228 .581/.588 114lsa
*TSP ported heads w/ stock width head gaskets
*MP122 magnacharger @ 5psi
*K&N Z06 filter element
*Widebody Kit
*Supercharger Hood
*Z51 Package
*HUD

What would be a good 1/4 mile time range?

On those street tires you probably wont see better than a mid 11.

Get some drag radials.

Depends on temp/elevation but I ran 11.2 at 3k, 70F on Nitto Invos. (572rwhp)

traction/your 60' is going to decide it.

Great traction 11.0
ok traction 11.6
poor traction 12.2

trap should vary less, hopefully you can hit 130

I'll give you the benefit of the doubt. I'm guessing you hit 10:75 before the day is out. Let us know how it goes.

dsmboosted

interesting. how much do you think the drag radials will effect the time?

AFVETTE

Considering a stock Z06 w/DR's can run 10.7

Your 100 HP advantage should put you in the low 11's and possibly high 10's.

Looking forward to your results.

Whatever happens don't get discouraged. Drag racing takes practice like anything else. Everything has to fall in place for a good ET, especially launch.

Good luck

dsmboosted

I appreciate the encouragement. i will post my times tonight or tomorrow. Im hoping I can hit low 11's. It will take some practice.

Quick question:

How much gas is optimal to have in the tank for best traction and speed? Its almost empty now so I can put however much is best.

Being your first time at the track with that much horsepower trying to get it to the ground........mid 13's is my guess to start.

But do NOT get discouraged....practice,practice,practic e...you've got a 10 second car for sure.

If you are the stock clutch and launch it hard on a good sticky tire, your clutch is gone. If you have a good clutch and sticky tires.. LOW 10s.

dsmboosted

I have the stock clutch....do most people updagrade the clutch with these hp #'s?

White_Lightning

if you plan to put sticky tires on it and run in the 1/4.. yes.. stock clutch WONT hold 560 rwhp on sticky tires from a hard launch IMO.

I'd worry more about a stock 05 rear at a track with those hp #s

Well, what happened? What did you run?

racerns

Please do not compare Ranger's best run ever, after 100s of attempts, in near perfect conditions to what this guy may run his first ime to the track with this car in it's current configuration.

dsmboosted

I ended up running an 11.977 for my best time. Most runs were in the 12.2 area. Temp was 75 degrees (unusual for Wisconsin at this time of year)

The track didnt have any tack down on it, which made me mad at the time because I couldnt launch hard. Now that I read through these posts, Im glad there wasnt tack. My clutch is fine and so is the rear end. No issues. Ill probably look to upgrade that in the future though.

FloydSummerOf68

What were your 60 foots?

How do you know that there was absolutely no VHT on the track? Did you walk to track? It is very rare that any drag strip will not have VHT down, even if you didnt see them heavily applying it. The fact that you are not able to launch hard has a lot more to do with the fact that you are on street tires. With your level of power you will blow them away in any situation.
