What is the "93 cobra super chip"? Everything else sounds good, but that sounds sketchy.

Why do you think its slow? What times are you turning? With a 5 speed that setup should be good for 12.5 to 13.5 depending on driver skill and tires.

the 93 super chip is a computer chip that goes betwwen the wiring harness and comp. to reconfigure your factory comp. we only have 1/8 mile tracks around here and im turnin like 9.2 on street tires (never run a slick YET!) and yes im runnin a bw world class t5 and im thinkin its slow b/c i got out run by a trans am LS1 yesterday (but only by a car lenght) i really want to know what my best next move or mod would be for the money i have 2 kids and 3 step kids and im on a tight budget but i LOVE the thrill of a good run!!

Do you have the MAF to match those 24lb injectors? Have you tried running it without the "superchip"? If so, how does it run?

mcbrides_ride · Mar 14, 2009

my mass air is a 73 mm C&L mass air unit is this not a good match for the 24 lb. injectors? and no i have never run it without the super chip it was on it when i got the car and i ve never taken it off

Since your only running 1/8 mile, go 4.10 instead of 3.73.
Try running without the chip.
Have you gotten a good tune?

Don't beat yourself up just yet, the question is did the LS1 have any mods that would have helped him out or was it stock, if they had any supporting mods then the car was no sloutch! It was hard to tell from your post but the way I read it was your heads are stock?

Get slicks. Also he meant is the MAF calibrated for 24 lb injectors. 4.10 gears would be an expensive upgrade unless you know how to do it yourself. Also, do you still have the stock e7 heads on there? If you have the means, port them out and gasket match them to the intake/exhaust. If you have the budget, save up for some aftermarket aluminum heads

All things equal the LS1 will win everytime. Those cars will go at least mid 13s stock with a decent driver.
Don't judge your set-up from this race.

I feel you, I raised my wifes kids (never had one of my own) all these years and now I am about to get the oldest to college soon! I got my stock E7's ported by Thumper Performance and since I live 6 block from him, it was easy and cheap. Alot of peeps have their own opinions about ported heards vrs. aftermarket heads, but I am more than happy with my set up and I am looking at forced induction now. Get the stockers ported, add a good cam with an adjustable timming gear set. Just me.

why so slow?
