Hey guys, I am going to the drag strip on Saturday and have been talking to a buddy who wants to run me. I will post results after, but just looking for predictions on who will win. I was thinking it will be a drivers race, if he doesn't edge me out halfway down the track.

You lose the race and for posting this in the tech section

Thread moved to talk

Oh oops thanks.. Still learning the forums

madspeed · Nov 27, 2014

No worries, moved it for ya

CarMichael Angelo · Nov 27, 2014

He's gonna kill ya.

You're carrying all that extra weight of the stuff you listed that won't add one, single, horse power.

master_bayshin · Nov 27, 2014

Sorry to sound uneducated Madmike, but what stuff are you talking about?

Btw we are both on street tires

Micheal Nadeau · Nov 27, 2014

A stock Z-28 ran the 1/4 in just over 14 secs. Your LX ran high 15's, almost 16 sec quarter. You may have picked up enough power to get you into the high 13's. His 4.10's and exhaust are enough to pull him into a really high 12, low 13.

master_bayshin · Nov 27, 2014

Ok that makes sense. Another buddy's got a 4.6 GT, mods include 4.10s, a can tune (Bama power flash) Accufab 70mm TB & Plenum, JBA catless H pipe, SLP loudmouth 2 mufflers, full length SFCs, & hitch kid rear LCAs. How do you suppose we'll stack up?

v8only · Nov 28, 2014

You've got the right mods for a high 12 second car on sticky tires. You should be putting out 300 at the flywheel give or take.. He's just got an old lt1 350 SBC in a heavier body.. You should be able to take him no problem

v8only · Nov 28, 2014

Also to the above poster, 5.0 5 speed cars were rated 14.3 in the quarter off the lot, it was the aod cars pushing 15/16 seconds

Shoomakan · Nov 28, 2014

You have a severe hp and torque penalty. Assuming you drive equally and both have good grip, I don't think you can take him. The weight difference isn't drastic enough, methinks.

edit: If the world wide web isn't lying, there's a ~250kg difference between a 4th gen F-body and a Fox GT. Sheesh. I didn't know the they were so heavy.

I'm not totally sure anymore. My BMW can punch above its class because I've gutted it. I can usually outpace a car that's 250 kg heavier and has 100 more horsepower, so I really think it's a driver's race at this point. Basically, try to keep him behind you until the finish line.

v8only · Nov 28, 2014

You're wrong shoomakan, a 94 z28 is only putting out 260 HP, his fox with gt40 heads will be 40-50 HP more than the z28

Don't forget, the camaros didn't get ls1 engines till 98

Shoomakan · Nov 28, 2014

Doesn't Eaton posi mean a positive displacement SC? IE the car is supercharged?

v8only · Nov 28, 2014

I took it to mean a posi traction unit in the rear end.

Good question

Shoomakan · Nov 28, 2014

I don't think Eaton make differentials, but I'm not sure.

Either way, if not SC'd, then I think the Fox is faster. If SC'd, I am not sure. LT1 heads are not that bad stock... it could be make good power.

master_bayshin · Nov 28, 2014

No supercharger. He has the factory 10 bolt with this posi unit

Not an LS1 car either. I honestly don't like the f bodies, I think they're ugly, hate the 10 bolt rear, hate the opti spark ignition. Do like the LT1 otherwise, love the T56.
All I know is his car is healthy, pulls hard. But IMO so does mine

As for the 4.6, I think I'll take him. My car feels faster. I believe we're pushing similar power levels, but his car is heavier.

Shoomakan · Nov 28, 2014

I think it's yours then. He has you slightly outgunned but you're much lighter. Unless he's running slicks and you're not, which you didn't specify.

master_bayshin · Nov 28, 2014

We are both on y rated street tires, both 275s in the rear

Don't spin off the line....
