Yeah just lookin for sombody to help me out here i had my car out at the grove on friday and really i wasent impressed with my times

the car an 89 formula with a 350 vortec heads and lt4 cam its backed up by a t5 and 3.45 gears and the best i could muster was a 14.450 at 96.93

The only reason it bothers me is because ive raced new ss camaros on the street and kept up very well but the track numbers arent there

help please

 

What's your reaction time?

What's your 60' time?

Are you using overdrive?

What are your shift points?

 

ahh the milloin dollar questiones


r/t .669
60 2.188
330 6.114
1/8 9.322 mph 76.23
1000 12.115
1/4 14.450 mph 96.93

im not using od and im rockin the stick at about 4500 to 4750 cause im still on stock runners is clutch slippage a possibility cause its a pos stock replacement from napa

 

Maybe just a bit, but if it were me, I'd be concerned with bringing down that 60' time. What kinda stickys you have out back? I've seen superior results from Goodrich Comp Drag Radials (highly recommended).

 

i was on street tires i just got the car like 2 months ago and i bought it built so i really dont know what the combo is good for but i expected a little more out of it than what its givin me

 

Once you get some tacky rubber on yhe back, you'll know for sure if the clutch is slipping. A real good gear & tire combo for our cars (in slightly modified form) is a 3:73 rear gear with a 26" tall tire. This will lower your 60 ft. times, but may cause your eng. to rev beyond it's peak power at the end of the strip. This is where tire size & gear ratio formulas come in. They will help you figure out the exact combo you need. I recommend going to a bookstore to find a book by John Lawlor called Auto Math handbook. This is a VERY INFORMATIVE book that can help anyone achieve their goals.
I wish I would have purchased tis book YEARS ago!!

 

I was pulling a 101mph with my old setup on my Formula. Vortecs, hotcam converter (auto) with similiar 60ft times

What tune are you running?

Highly suggest you look into that and find a lot of untapped potential. I was running the above blowing the dipstick tube out on the motor :-)

later

see heres where it gets funky the guy i got the car from suppossedly had a custom prom done but i really dont know whats up with it the other thing is that its not an lt4 hot cam i believe its the stock lt4 cam which pales in comparison and i know the stock runners on the car an issue but could that be the main issue here?
