I will try this again.... since the last advice was to get tires. Now I have QTP's and they hooked like a **** (saw in a pic). I just dont understand why my car refuses to 60ft. Here is my current set-up....

355hp/436tq (unlocked)
3600 vig
Front Hals with springs
SFC
LCA's
PHR
Bogarts w/ QTP's

I have tried taking it from idle - 1500 and then flashing it... and footbraking up to around 3k to where I am almost pushing through the light... and it doesnt matter either way. I am also running my tire pressure from 13-16 lbs and no difference.

Any suggestions would be appreciated

Oh and my best 60' is only a 1.67

You're kidding right??? You are complaining about a 1.6x 60'. Maybe it's just me, but I'd be pretty happy that, considring your torque numbers. Just out of curiosity, what are looking for?

need more info.

are you bogging or spinning?

what are the specs(size) of the tire?

what rear shocks and springs are you running?

what setting do you put your front hal's at?

is that a tight spray converter or a loose motor converter..i.e..what does it flash to?

that outta get me started

You say you have bogarts with QTP's, what are you running on the front?? Hopefully not those heavy Z06ers or that is part or the more of your problem. I ran that converter in my car when it was stock internal and I pulled many low 12's and high 11's (best being an 11.7) with mid 1.6 and low 1.6 60's all day long. What elevation are you running at??

hmm, have you put an aftermarket torque arm on there yet?

CamaroCain

What does he need that for? I still run my factory Tq arm.

I see in your sig that you have 3.42's is this correct? If so put some gear in it, but i dont see you getting any better than a high 1.5x

I know you have a fast car and respect your accomphlistments. The torque arm assists in adjusting the pinion angle to keep the drivetrain poping too high on takeoff---which i imagine you already know---anyway the mod is not too expensive and it may help your car just a tid bit. Everything little bit helps as the old saying goes. cheers and happing drag racing...

if you dont have skinneys get some have you ever put your front wheels on the scales? the lca relocation brackets will help i use the spohn they look better than the ones that cost twice as much. if you dont road race get rid of the front sway bar. put your front hals as high seting as pos without spinning . pulling up uses up motion that could be used to go forward. also a gas shock will bounce back harder than a oil filled shock so loose the rear shocks use stock springs drag launch transfer weight but too soft.

dd96- I am hoping for hight 1.5x's... remember that I am an a4 car

silver- I think that I am dead hooking... and I am running 26x11.5 15's. Right now I have stock shocks but will be puttin on hal's in the rear very soon. I tried my front shock settings from 1-4 and did not see any difference. As far as the converter.... I bought it used but I was told that it was for motor. I may be getting a larger stall here soon.

Cain - i have skinnies on the front.... and that is my point... I should at the bare min be cutting 1.60... I know a guy that has cut 1.58's on nittos with the EXACT same setup

Taner - no I have not put on an aftermarket Tq arm yet... though that is in the plans.. probably a sphon

9secbird - there are a couple guys that I know are running 3.23's and cuttin mid to high 1.5's with the same setup that I have.

Keep it coming

taqwache

your hooking better then me but my suspention is completely stock. if you are dead hooking, i wouldn't think any suspention mods will help. what is your race weight? you might just need 3.73s if you got a pretty heavy car. ask those other guys with 3.23s what there wieght is.

brandboZ28

iTrader: (2)

Bingo!!! I think you need some gears

DEEZ98Z

iTrader: (5)

My race weight is around 3450. The two guys I know one car is 3400 and the other 3500 both cutting better 60ft's.
I have a rear with 3.73's in it sittin in my shed.... I may have to give it a try. I may do that and a larger stall

I think we needs to play on the 60ft w/a smaller tire! Which will effectively change the gear ratio.. On Ed's car we used my 11.5's which i think were about .5 inch too tall and killed him out of the hole.. I cut a 1.58 on a 315 Nitto on a comparably equipped 02 w/ 3.23's w/ the factory ugly spoke's on the front..

how much PSI u running in the tires?

Also you need someone to watch your car launch. Sometimes it may feel like the car is dead hooking to the driver when there's actually a little tire spin.

illusion - I was told by the hoosier dealer that the 11.5 will not change my gear ratio... even if it did the worse it could go down to is a 3.23 and like said above is what my freinds are using and they are cutting 1.5's all day long

badass - i have tried 12-15 psi with no difference noticed. I have a picture of the car launching and the car dead hooked... well that is what the wrinkle walls said

boomcase

Dam i have a full weight car 3530 with me in it (see MODS)and with my 342s i can cut high 1.5s on motor if the track is hooking good , I have stock shocks and springs also, I may have to agree with some that tire may be slowing you down a bit but not much. It looks like your dead hooking by the pic , but it also looks like you have alot of squat and lean to the right , what was the weather that day , was the DA high. heres a pic of my car launching , i dont have much squat at all. I was under the impression that to much squat and lean would hurt your 60ft, but I may be wrong. Someone correct me if i am ..

DEEZ98Z

iTrader: (5)

Boom - the DA for that day was between 600-1000... it was gettin higher throughout the day. That may be true... I have an airbag that still needs to go in and some hal's for the rear. I am hoping that straightens things up.
Actually to me it looks like your car is squating to the right... but since that pic is taken from the left sid you cant see it. What size tires do you use?

You need an air bag in the passenger side rear. I doubt that the Hals in the rear will help at all. If you do get them, set them at about five clicks (stiff). You are also killing your launch by having too little air pressure in the slicks. If you can't hook with 15 psi in them, you need to work on your suspension. If there is nothing wrong with your factory torque arm (bent or broken), it is also not your problem.


Good Luck,

It would seem that with all the changes you have tried that the convertor is just not a Vig.3600 stall.I still run the stock torque arm and have gone 1.48 best to 1.50 average with my Yank 4400 with just about the same suspension set up[I do have rear Hals and an air bag],3.42 gear.IMHO,if you install rear Hals they wont drop your 60' by a tenth.

When I ran stock internals at 325 rwhp I still pulled better 60's than you are now which is why I think your convertor is maxed out.Hope you get it sorted out and maybe find out it is something other than what we have here.
