i recently bought a 94 z28 camaro it has performance exhaust.a chip.and ls1 powered.

so over the weekend my dad ran the car cause i have no licence yet.first pass he had .216 light a 2.05 60ft. 9.08 eighth mile at 75.80 mph and a 14.14 at 97.55.

second pass-.122 red.
2.108 60ft
9.141 eighth mile at 77.09 mph
14.216 at 97.11 mile an hour

final pass- .045
2.08 60ft
9.110 1/8th mile at 77.21 mph
14.174 at 97.17 in the quarter

would any body say there is room for improvement??

 

If its a tuned ls1 with a cold air intake/exhaust your missing about 7-11mph and around a full second off the et. Now if your at at 4400ft the times will make sense.
Whats your location?
Who did the motor swap?

Are you sure its not a LT1,a maybe a high milage one? (100k+). It would make sense if it is and a auto 2.73 gear but otherwise you are having some issues.

The 1/8 mile and 1/4 mile traps is on the lower end, but the et for 97 mph is normal.

There is much room for improvement. Tell us more info.

 

the car only has 72000 miles on it. yes it has cold air. the sea level i have no clue but i live in maryland. and it has 3.23 gears so the guy said. and for whoever did the motor swap i dont know so yeah. does this info help??

 

if its an LT1 it makes sense, otherwise many things are wrong.

 

I figured an Ls1 would run better than that...

 

take a picture of the engine bay if you can, that'll tell us if its truely an LS1 or if its an LT1

 

The guys are right. It seems the times posted would be more in line with a LT1 and the mods listed.

 

My '94, with just headers, drag radials, cold air, and a short throw shifter ran consistent 8.6s at 81mph in the 1/8 mile...

I suspect that "performance exhaust" is a cat back system and not headers... Headers will make a fair difference in performance.

A set of drag radials will help get the sixty foot time down as well as a gear change to 3.73s.

The '94 does not come with a "chip" but is a flash programmable computer.

If you actually have an LS1 engine you have a whole additional set of problems since the LS1, out of the box, is quicker than the LT1 by a measurable amount...

 

OP
does your engine look like this


or this

 

i found out yesterday from my gilrfriends dad that it is the lt1.
