i have a 91 camaro 350 slp runners, ported pleneum and and edlebrock base i went to the track yesterday and my best run was a 15.2 =( and i deas why its so slow?

rt .108
60 2.424
330 6.495
1/8 9.840
mph 8th 73.45
1000 12.742
1/4 15.204
mph 91.56

 

Well, for one, your 60 ft time is extremely high, even for a third-gen. throw a set of drag radials on and cut that down below 2.0 and youshould see a nice improvement on ET. Also, if all you have done is the intake and not gotten rid of the stock exhaust manifolds you're really holding yourself back there.

 

yea i have the stock manifolds will they make that big of a difference?

im debating a ls1 swap thats why i havent added them yet

 

well your 60foot time does suck, but a 91mph trap speed is only good for a high 14 or so. The intake mods aren't gaining you anything without a full exhaust, headers and cat back with high flow cat. Some of these cars are factory freaks, but most I've seen are only good for low 15s to high 14s at best in stock form. Get a better exhaust on it and see what happens then. What gears does the car have?

 

i have the 3.23 gears i believe what evers stock

will shorty headers from the thirdgen fit a ls1?


what do you think ill run with headers?

 

Nope, not even close.

JFWIW - my car was by no means a freak. Pretty much stock save for K&N's and a TB - I went 14.4 @ 97 MPH with a 2.26 60' foot. (dry-rotted street radials)

Something is up, before I would spend another dime on performance parts - I would make certain everything is good. Leak down test, verify base timing, check the FP w/ a good gauge to make sure it has plenty of fuel delivery, read the plugs after a pass, etc, etc.

Where are you located? What track did you race at? I'm curious to see the elevation and the DA for the date & time you ran.

Just my $0.10

 

i checked base timing and it was good i am hoping i just have some piston slap setting off my knock sensor 150,000 miles on the engine i have to check my fuel pressure

i ran at fontana speed way in cali it was about 90 degrees out

 

That's bad, like real bad. Did you have about 600 extra pounds of weight in the car? Seriously the slowest 350 car I ever saw run was an 89 Formula, it went 14.7's and when I pulled the tune it was pathetic, it barely had 30 degrees of timing and the curve was lazy as could be. A quick prom swap fixed him up. I think you have something wrong, like a plugged up converter, low fuel pressure, or a knock sensor itself going bad. I've never heard of "a little piston slap" setting off the knock sensor so bad as to slow one down like that.

 

maybe some one can take a look at my datalog and tell me if they see anything?
