Dyno Guesses & Bench Racing Forum - Wondering what my time will be tomorrow

Going to maple grove tomorrow night and was wondering what I'll run In the quarter mile. I'm hoping to run in the 12s and what kinda power I'm making in my 1998 z28

Mods.
Slp lid free ram air mod
Slp catback
Egr/air delete
Ls6 intake
Port & polished throttle body
Msd wires and ngk plugs
Stock 342 gears

Car weighs 3,360lbs
122,000 miles

No tune yet. Also what kinda horsepower am I making my guess is maybe 340rwhp ?

No one?

if you can drive the car i don't see high 12s out of the equation. but on street tires with stock exhaust...i don't see it being easy.

i'd guess 13.0-13.2 @ 106-108..

Yeah they are street tires 275s. Would hope I could do better then 13s but don't have long tubes or a ory yet I guess that's what is holding the car back

Stick or automatic? If it's a 6speed you are going to torch street tires. You should post your results afterwards. I am taking mine to the track(Virginia Motorsports Park) for the first time next Friday. Run plenty of cars but this will be the first time for my newest project.

6 speed M6 t56 upgraded with Kevlar synchros stock clutch and hydrolics removed clutch spring. Yeah I'll post my best time up first manual car at the track

I see a best of 13.0 without tires. Right now you are probably making 325 or so without headers.

60' 2.280
1/8 9.110 81.72 mph
Et 1/4 13.852
104.55 mph

Was having problems with the hydrolics where it didn't let me go into gear at redline so I couldn't jam it into gear like I wanted to this was my first pass the 4 after it kept missing 3rd felt like it was inbetween 3/4 wierd. Clean fluid and a 5.0 shifter

heres my 2nd best where i missed 4th and hit the brakes to try not to run 13s with no helmet
60' 2.251
1/8 9.004 82.42 mph
1/4 13.957
89.05mph

if i didnt miss 4th in that run i bet that would of been the best run

Just practice more. The 60' is killing you. Tires and getting that clutch issue worked out will go a long way.

Yeah my buddy says i need to get a TickMaster cylinder, thatll probably be my next mod then qtp headers with ory
