hey im like 19 live in central west florida and have owned 4 camaros 2 3rd gens and 2 4th gens and been into cars for 7 yrs now i swapped a few motors and did a few things here and there built my last motor (lt1 with cam ported/ polished heads and intake 2X 58mm TB and alot more even needed compuiter tuning.......ist what i need help with at the 1/4 mile track)

i got done to it is:
(1)11:1 compression (up from stock 10.5)
(2)ported and polished intake and heads (not sure how much better they flow)
(3)stock crank and rotating assembly except for 2 valve relief verses 4 stock 4 valve reliefs (bumping me up by 1/2 compression)
(4)28lb accel injectors verses stock 24lb
(5)2X58mmTB by professional products
(6)comp cams extreme energy #07-503-8 camshaft its a 276/280 advertised cam with 503/510 lift at valve and 225/235 actual duration @ .05 lift
(7) centerforce dual friction centrifugal weights clutch
(8) mickey thompson e/t street radials (315-40-17r's)
94 t56 borg warner with 2.94 first gear with stock 3.23 at the rears..............
power is : 270hp @ 5400 and 310ftlb @4300 but torque curve is pretty much completely flat fron 2100- 4600.... i was told this is probably = to 380hp about with 410-420 ftlb at the crank....

problems ive had is i cant hook up im launching at 4000rpm shifting at 5500 and im literally spinning my tires ALL THE WAY THU 1ST GEAR and THIRD OF THE WAY IN 2CD GEAR AND CHIRPING 3RD........ and ive even did the "nice smokey burnout the tire started squeking once out of the water... and olny pulled the best so far a 14.051 @ 102 MPH and only use 3 gears but im about to shift as i hit the lights (turning 5700) at the end of the track....

ANY SUGGESTIONS ive been told i need more gearing (3.42 or 3.73), my tires are only 6 months old (i have no idea how long that sat in the wharehouse in china) ive been told with the amount of stuff done to it i should be into the low, low 13's and i cant even get out of the 14's any help

i dont wanna sound like a jerk but please be creative i dont need to here "yahs its the gearing man" how much would that eibach drag launch kit help (it has i think stiffer in the rear springs left and right are different rates and right side has and air bag with taller progreesive rat springs in the front)

Well let's see if we can help you out a bit.

You make no mention of any suspension upgrades, that is going to be what you need to look at first. It makes no sense to have all the power in the world and no way to get it to the ground. I am a firm believer that you first start with the suspension, then do your mods to make more power. In my car when it was stock other than a stall with all the suspension done, I would get 1.5-1.6 60' times on a street tire.

So, things you will need to start......

A good set of rear lower control arms, adj, and relocation brackets

A good Panhard bar, adj

A good torque arm, adj

Subframe connectors.

That will be a good start to getting you on the way to hooking your power up. I personally run all UMI performance products on mine. Once you get those basics in place, you can move on to more as you find what your car does at the track. If you get the right parts in place, you won't even recognize your car as it will feel like a whole new animal.

i know suspensions a key part to any car but... why can a flat out stock LT1 car get a 13.8 at 98 and im doing 14 .05 at 102 ? what give and a 454ss chevelle stock did 13.4 at only 103...

am i missing something here and there suspension wasnt modified and a matter fact "hotrod magazine did that testing on a 95 firebird and they got it to do 13.8 at 98 mph "BONE STOCK".... im not defending myself im really perplexed!!!

You don't need a panhard bar to go down a dragstrip. Panhard bars are for centering the rearend during cornering.

You need traction. What tire pressure are you running your tires at? There is no way you should be spinning for that long with the power you are making. Why do you keep your foot in it when it is spinning? That's just ridiculous. Why don't you try a different launch technique instead of just putting the hammer down? I'm thinking you just need more practice before you spend any money.

Any dyno time to determine actual power output? Maybe there is a problem with the tune.


I am with Joelster though...no way should you be able to spin those particular tires that far. Sure the clutch isn't slipping to high hell?

While it may not be required to have an adj. panhard. It is a wise decision for centering the rear. When you start moving things around it is better to have the flexibility to adjust. While there may also need to be a driver mod, practice on launching is important as well. While you have stuff done to your car as well, making the most out of it requires it to be tuned right. You could be leaving a ton on the table.

i do keep it hammered well its spinning which i do agree is stupid i guess its my launch speed ill try 3000 or 2500, and "slowass" (haha highly doubt its slow) and i only dynoed it after tuning it (which ive done myself with tunercatz) {awesome software and reasonable price} i never "dyno-tuned" well on the dyno... and on the other hand im not liing ill have some one video tape me at the track i really some how am spinning all the way thru first ??? which i cant understand myself... and by now means is the clucth slipping at all cuz my rpms actually stay way low well im spinning then its start revving once i cetch traction... and tire pressure i tried all the way from 26psi down to 16 18 the sweet spot because when i go down to 16 it starts to slip even more...

I Mean Could It Be That Im Giving It To Much All At Once And That'll Solve Everything Because Ill Do A Nice Smokey Burnout And Theyll Start To Squeech And Then When I Lauch I Dont Cetch Traction Its Reatarded It Like Doing Another Burnout At The Tree And My Car Even Turns Somewhat Before It Goes Ill Like Sit Spinning For A Split Second As I Launch (again)
