Excuse for being the new guy, I have never really been into racing a whole lot just showing. With a car like this couldn't you potentially knock a decent bit off the time by just getting some slightly stickier tires (nitto 555's?) and putting some high octane fuel in it (110)? Or would the fuel hurt it? Like I said, I have been away from all of this for a while til the wife gave me the go ahead for the car, and I was always into showing before, never been much of a track guy, but with this little beast I can't wait to take it out and start runnin.

fuel wouldnt really do anything unless u tune the car. unless u put that XXX oxygenated fuel. that **** gains like 15hp. stickier tires always help at a drag strip. 60' times are critical.

Your exhaust might have a nasty leak.

Just tune the NAWWWZ timer, you'll run nines.

when Brian said to Dom, "now, you owe ME a 10 second car". i wished Dom would have broken into a 370z.

any chance of the Z being a real 10 sec car after all the mods people are building for it?

Great times! I have a 370z 7AT as well, did you use the Manual Paddle shifters or did you leave it automatic mode (D)?

No. Not with any simple bolt on mods. Power has to be HUGE to push a 3000+ lb car into the 10s. Especially without a properly set up chassis.

There are basically two ways to do it. One requires (in addition to a big power increase) modifying the chassis and rear suspension to get the car off the line HARD.
Different wheels and tires for sure which means different brakes to fit those wheels. Unknown how the suspension would be able to deal with that kind of launch. Would it remain stable and put the power to the ground? I doubt it. Would it break? Probably. I'm going the bet it would break.

A serious 370Z drag car will probably have the entire rear end and suspension replaced and you'ld have to be a demented drag racer type to do that.
When dealing with that type... anything is possible.

The other (preferable) way would be to go easy on the rear end and give away a hard leave for a HUGE top end speed.
Now you're talking turbos with enough power to produce quarter mile speeds of 140mph or better to make up for a soft first 200 ft.

Can the trans take that? Maybe the auto with some mods can considering that you aren't really going to be hooking up too hard. I'm going to bet the manual/clutch wouldn't. At least not without babying the shifts which means you'll need even more mph to make up for that.

I think you will need 700hp to see the finish line speeds necessary to put one of these into the high 10s without a drag suspension and tire setup.
Under drive pullys and HFCs just aren't going to get it done.

Great times! What tire pressures were you running and did you take any weight out of the car before going to the track?

ZforMe 04-21-2009 05:54 PM

In response to TBSS2008:

I paddle shifted as close to redline as I could.

In response to Namir:

All tires were factory filled with nitrogen to 30psi, i did not change them at all.

Car had everything in it that a new stock model would have, minus the manual & other booklets. Here's the kicker, I'm a thin dude 5'11, 140lbs max.

Next time out you might try letting some air out of the rear tires and over inflating the fronts. And obviously anything you can remove from the car (spare/tools/sub/carpets/windshield washer fluid) and low fuel levels might help you shave a couple tenths.
You planning on heading back to the strip?

"demented drag racer type" and just what the heck is your meaning behind that statement? I guess you prefer the "Good ole boys" that run around in circles with restricter plates going no where for three hours or so. :twocents:

good pointers, I'll try a few, in my first runs I wanted to be as close to stock as possible. I'll be headed back again some time in may when my buddies are free to run their cars (Pontiac g8 & 06 350z, yes I can smoke them both).

The tires that these things come with are a huge handicap on a drag strip and to do any better than a 2.0 60' is going to be just about impossible imo.
A race type tire that gets sticky when it gets hot (like a drag radial) would be a big help knocking a couple .1s off that 60'.
With completely stock trap speeds showing up in the 105+ range, I'm going to predict that with the usual bolt-ons (exhaust, pullys and maybe a decent cold air intake) we'll start seeing 110 mph finish line speeds and ETs solidly in the mid to high 12s.
Makes me want to do it but I'm getting the eye from the wife...lol.

I'm convinced this car can click off a 1.9x 60'.

I need to get my *** out to the track and try it myself. I've done it before in different cars that might be a little more suited for the launch... but on much skinnier, less-grippy tires.

Considering that I've got a couple thousand passes down NHRA tracks from one end of the country to the other, ranging from 7 second motorcycles and 8 second Mustangs to stock tired 13 second street cars, I think I know what "demented drag racer types" are thank you....:tiphat:

eXo5 04-22-2009 09:43 PM

I would be happy to break into the 12s with a Z with bolt ons.
