Trying to get an estimate for what my 1/4 mile would be with these mods.
assuming ok traction from a non posi
92 rs 305 tbi 5speed
heddman headers and y no cat cat-back from an ls1
cold air intak using a tpi dual snorkel, no air sys.
march crank pulley ls1 alum drive shaft stage 1 comp chip
vehicle in decent tune w/ 93 octane (bc of chip) 3.08 gears,
standard size tires (and poss. an ult tbi w/ inj pod spacer)

not expectin too much but...
let me know what you guys think

 

16's

 

hmm, i was hoping for better, the car should run mid low 16's now, and half of the mods listed are still sitting in the garage
waiting to be installed.
i know traction is prolly a huge issue, (well, besides the obvious peanut cam and swirl port heads)
oh well, thanks

 

If in doubt, take it to the track and find out exactlt what it will do. I just look at your listing as nothing special but a 305 with highway gears. Your chip may give you a few extra horses but don't expect much from the rest of the stuff.

 

Agreed.

 

a fellow member TraviZ had an rs with I think free mods and a catback and ran a 15.6 all day but it was a 3.08 posi 5-speed

I'll say mid 15's don't they run 16's in stock form

 

from what i have seen they run mid 16's stock and low 16's w/ a 5speed, but people w/ more drag strip exp. would know better.
the only facts that i have to go on is that my friend ran his 95 gsr 4 door to a 16.2 in the 1/4, and i was able to get a fender up on him in a street race, till we hit about 60mph.
(I also had HORRIBLE traction issues, but I'll be getting better tires definately and if i have money to spare, a posi and gears)
the only mods that i had done at the time were
march pulleys,
new clutch
stock exh. w/ no muffler
alum. driveshaft
and open element
160* t-stat (car runs pretty rich right now)

for the winter i have these mods in the garage
stock ls1 cat-back (should flow the same or better since the larger diameter tubing)
heddman headers and y-pipe delete AIR and cat
dual snorkel from tpi setup to make custom CAI
stage 1 comp. chip
and some weight reduction
tbi injector spacing (and poss. an ult tbi and afpr)
complete tune-up
and any other cheap or free mods that i missed im open to sugg.
I'm hoping for a low 15, but that's just the goal for now...
*i know the heads and cam ultimately limit me, but i'm not touching the engine till she blows
