14.1 at 98.81mph (how to improve)

I am trying to get my daily driven lt1 '94 Camaro into the 13's. Traction on this run was ok. I say I can launch better and get a better e.t.
.400 tree speed
.648 reaction\
1.955 60 ft
98.81 mph
14.13 finish
My Camaro has bolt ons only. K&N air intake , airflow elbow, computer tune( madz28), 4.10 gears, rebuilt trans(transgo shift kit), 3600 fuddle stall and 26 inch mt et drags.

I think your stall is killing you. It's WAY too high for a basically stock motor.

You should be close to LOW 13s with 4.10s and a stall. I wouldn't go higher than a 3200 on a stock motor. I went with 3200 only because i plan on adding more power SOON. 3600 basically puts you WELL past the torque peak. I HAD a 3k stall til my tranny blew. Oh and with DRs you should be in the 1.8 60' area. that ALONE will put you in the 13s.

A 3600 stall is for a cammed car, I'd say.

WRONG...3600 stall+Et Drags+4.10's should equal a KILLER 60 foot time. Even if everything else is stock. There are issues hidden somewhere. What elevation are you at?

3600 puts you "WELL PAST THE TORQUE PEAK"!? It's aggressive but it's not wrong by any means. First off it's not exactly a peak with a stock engine. It's more of a flat'ish forgiving torque curve... 3600 puts it in a great zone and in a good distance from peak HP and roughly a 5800-6000 shift point.

Could there be issues with the stall in relation to the tune?

I agree with AutoRoc. The converter is not the problem. You have something else going on and need to find out what it is. Good luck.

+2 on that!
At normal altitude (not colorado or new mexico etc.)
with your set up you should be in the mid 13s,that stall is sweet,mixed with that gear you should be rippin the 60'!

are you trying to launch the car on the converter?
if so try launching from idle speed to get the converter to FLASH!

What altitude and weather?

And with that stall/gear combo it's absolutely necessary to have sticky tires if you want to get a good et.

His trap is right where it should be. That means nothing is going on except a slow launch.

It's a basically stock LT1. What do you expect it to trap??

To the OP: Are you hitting OD before the 1/4 is up?

4.10s and 26" tires are @5200 at 98mph
1.95 sixty foot is in the mid 13s

I'm thinking either exhaust is choking and or suspension is not doing its job

tire pressure? launch rpms? hand shifting or leave it in drive?
If the speed were higher, I would think only the launch is effecting his et. if the tires are unloading and spinning down track?
could be he is in Denver

mine is a stock lt1 with a lot of extra crap that doesn't necessarily make more hp just uses what it has

You have LTs with true duals. You don't think those add power?!? How about a bigger tb?

Yes, his ET is low, but his trap is normal.

low trap = high gears.

give us a location... for all we know you are running great times b/c u could be at like a 8000+ DA.

I'd look into your suspension/launch. What suspension mods do you have done? It appears you could cut a mid 13 second pass with it, if you got that 60' down.

haul to the track, if you cant haul get there early to do a proper cool down
go with about 1/2 or lower gas in tank, high octane
remove spare and jack, tools ,what ever extra in car
lower air pressure in rear 18 to 20psi is safe start
raise the pressure in the fronts to max or get skinneys
remove the front sway bar , wont hurt the drive to the track, unless you live in the mountains
do a proper tune up if its been awhile, plugs wires fuel filter, clean air filter
you can spend a fortune on suspension, start with lower control arms then torque arm, sub frame connectors, panhard bar, may be air bag in right rear,
hows the shocks?
My guess is your car is unloading the tires with squat possibly spinning after 60'
do some exhaust long tubes and free flowing cat back
is the car pulling all the way, hard? running right

trust me with the 4.10s and stall, decent hook, and long tubes you will forget about 13s and worry about 12s

I hope this helps, good luck

Track location is a 4000 ft . The tune I got from madz28 was before I added the 3600 stall. My suspension is completely stock, I was running the tires at 28 psi, leaving the shifter at D to let the computer do the shifting. As far as exhaust , it's stock(got longtube pacesetters ready to go on). I was loading the converter and never tried leaving at idle and letting the converter flash . The car doesn't pull as hard on the top end as it does at launch up to mid track. I need to install those longtubes and see if it pulls harder up top.
