I went to Hattiesburg MS today to Hub City Drag Way, $15 for head to head racing from 2p-9p. I took out the spare tire and jack and al other lose junk. I was on about 3/8 of a tank. It was 95F!!!, 82% humidity and 400' above sea level. I made 23 pass's!!! Street tires at 30psi. Stock clutch. Launching at 3k with an easy clutch release.

Best 2 NA runs
14.890 @ 93.975mph w/2.171-60', .688RT
14.927 @ 92.427mph w/2.138-60', .878RT

Best 2 Nitrous runs
13.894 @ 101.643mph w/2.190-60', .705RT
13.990 @ 105.352mph w/2.195-60', .896RT

Suprisingly enough my stock clutch held the 100hp shot in 4th gear. However I think a better clutch would help allot, not to mention some drag radials.

A few other guys went too, thay ran pretty good! I had a blast.

 

hehe...check out my post on how I did guys.

 

Gret times Matt! Just wait till winter and you will have faster times!

 

nice runs, 2.1 60ft's on street tires? thats really impressive.

 

Great runs Matt, 13's on street tires!! Wish I could have been there.

 

Thanks guys! I was shocked. I was wondering what those 55 gallon drums that said VHT were their for? The track was way hot, so I thinked that helped allot also. The funny thing is I was spraying in 1st after it hooked up. If you notice my NA 60's are faster. I guess 2.1 is about the best I'll see w/street tires.

 

great job!
i still dont understand how my boy Jamie ran 12.8 on a 120shot in his max.
yea he was on slicks...but that aint no full second.

 

Thanks!

I was granney shifting very slowly with the nitrous, I didnt want to blow my clutch up. I also use a push button that I have to push and hold for the nitrous to activate, its a saftey thing. If I just put a master switch and let the window switch and full throttle switches handle it I might run a little better because their is a delay for the time it takes me to push and hold the button.

I bet Jamie ran that time on a nice cool northeasten day not in 95f. Drag radials would knock 1/2 a second off I bet. I had 2.1sec 60's so dropping 0.2sec to a 1.9sec 60' would help allot.

My second best ET with the nitrous was 13.990 but with 105.3mph trap speed, thats moving it on down the road!!! I think Sleeper has run 13.3 @101 w/1.9-60' with drag radials. So I can see how a 120hp shot could get a 12.8et.

But a 120hp dry shot IMHO is not safe with out an a/f controller and/or larger injectors, not to mention a few degrees or ignition retard. With my 100shot I was @12.5/1 A/F ratio with the wide band OT on the dyno putting down 257hp & 284lb/tq at the wheels. Some day I might try the 120 but for now I'm saving up for a clutch!

 

nice... but I can't believe you don't change your tire pressure... I always run .2 better with front tires at 23 and rear at 35.

 

Job Matt!!!. I can't wait till I get my system tuned in. Nice runs!!!

 

Thanks.

I did lower the fronts a bit, I run in the streets with ~34 in the front. When I went to 30 and got 2.1sec 60's I thought that was good enough. I would have liked to bump the rears up to 35+ but I forgot...


Thanks mtrai760, you'll love the nitrous its like crack!!!

 

Congrats Matt, man it seems everyone is hitting 13's now a days Good run

 

Thanks Adam!

Shall I dream a little and say low 14's NA and 12.999 on Nitrous by 2002. Why not

 

That sounds respectable to me Keep us informed on the progress, I hope to be right there around those same #'s, just be sure to keep the A/F mixture right we don't want a kaboom. Are you going to go with the 370 CC stock 300Z TT injectors? they are about 100.00 a piece new, plus a JWT ECU to complement it, and I think you should have enought fuel.

 

dude, drop the front tires down to 24 and see what happens... I bet you can pull 2.0 60s or better... you need that surface area for a good launch, this is the easy way you'll bring your times down.

 

The way to a 125ish shot for me is hope that that new MSD control box will work on the Max and give me a fer degrees of timing retard. Cause their aint no darn way that JWT is gonna have an ECU for the 98's in this century! Once the timing is done, an AFC to adjust the injector pulse width to max should provide enough fuel with stock injectors at ~80psi of fuel pressure.

I'm looking at doing the 5g intake swap. I have both shop manuals and it looks do-able. The intake should arrive to me this week. So that should do it with the NA numbers.

Slap some drag radials and a clutch on top of that I'd be good to go.

I also just bought a set of used 95 heads...

 

I'll do it. Its worth a shot. I have 225's on 16x8's so I'm leary of cuping in the center of the contact patch. But WTF 2.0's would be nice.

My next time to the drags wont be until late July or early August, and Ill try to go on to an night time session so its not 95F!!!

I have 225/45/17 Sumotomos and I run 26psi in front. I pull 2.0 60'(206) my best. I have auto so its a little easier. Nice runs though. What was your 1/8mile time and speed. Cause I run low 14s 14.09@98 my best and I run a 40shot. My 1/8mile is high 8s@79mph

 

Thanks! 98MAX

I'll try it for sure.

best nitrous'd 1/8
9.045et @ 81.737mph
best na 1/8
9.560et @ 72.002

 

Just a question. When do you hit the NOS. In first yet or second.

 

I launch at 3k and feather the clutch out. It hooks solid at ~4500-5k and thats when I hit it.
