If I had 500-600whp I'd rather fry my tires on a 1st gear launch than my expenive race street/race clutch and flywheel on a 2nd gear launch. But then you have the high-hp guys like BriGuy above you saying he doesn't spin off the line, so there you go. End of debate.

 

hahhahahaha 2nd gear launch hahahaahahahahahaahhaa <breathes> hahahahahahahahahaha

 

ok ok I guess ill just give up this line of thought, Briguy what rpm are you launching at? Type and diameter of tires at launch ? diameter of tires at the trap? RPM when you trap?

 

I don't know what conclusion you think you can come to with this information, but here goes.

I launch around 5500-6000rpms with very close to a full clutch dump. I run a 26x10.5x15 M/T ET Street tire. I don't think the diameter of the tire changes much between the launch and the trap...so we'll go with the same. I'm not exactly sure what RPM I run through the traps at...but it's 120-121mph in 5th gear which is around 6000rpms.

 

My sentiments exactly

 

start in 5th gear next time. that will get you in the 10's and better yet NO chance of a missed gear

 

bri pm me next time you go out and i will stand at the trap with a ruler to measure your tire diameter as you go by. i do it all of the time, just in case someone asks the stupidest questions in the world, i can hvae the answers

 

ok maybe the second gear start was a stupid idea (i got the idea when my friend took me for a ride in his new z06 he hit 0-60 in first taking only around 4 seconds) i was under the assumption you were launching on d/r or another suto drag tire sounds like your using a decent dot drag poly ply , knowing tire diameter at trap is very usefull as tires do expand if your running a wrinkle side wall at low psi the tire can grow about 25% having this information can help you select proper gear ratios to ensure your are hitting redline as you cross the trap (using your hp and enigine to its maximum potential).
It seems you guys want to get better times with out building a whole car just making more hp, with 500 hp with proper suspension and tires gears its easy to turn low 10's even breaking into high nines.
Yes i know the guy with the ostrich thinks im an idiot but I have gone into the nines with a street car, alibet tubbed and with a locker but it was just shy of 550 rwhp..
My Z is the first car ive owned that was 1, Japanese, 2 not a v8, and 3 lol very dependible!Its alot of fun but as far as a solid hook and launch well not that great but what would you expect from 19's with a 35 profile?

 

Funny you should mention that do you know how the fast cars do it? Im talking 0-325 in four seconds you think they shift? lol you have alot to learn about drag racing, ill give you a lil hint though, (clutch packs) a single gear and a ton of horse power as the tires expand and the clutches grab . But what do i know about drag racing?lol

 

I won't touch that comment, but launching in 2nd gear in a 430whp STREET car is retarded.

 

Since when is a tubbed car with a locker considered a "street car"??????

 

that is the most retarded isht i've ever read...

 

That's a pretty general statement to make. Maybe in a <=3000 pound car with a stalled auto and a tire and suspension setup guaranteed to hook up.

I think you should step back and realize your audience here.

I'm in agreement with "the ostrich guy" and you're comparing apples to oranges. Tubbed, Slicked Race cars with TH400's and Powerglides have nothing in common with the 6-speed, 350z street cars in this thread. IF your TH400 has a manual valve-body, start it off in 2nd gear at the track and let us know how you do. I can't believe the amount of bad information you've interjected into just one thread.

And what did you run in your 350z? I suspect you should be taking advice from these guys, not trying to give it.

 

Actually the NHRA Street tire class is pretty F'in lame..They consider a tubbed out Supra with a parachute, a street car cause its running drag radials..lol

 

Seems like almost all those race series' have classes are like that. They take no consideration of the "setup" of a car they just look at the tire and class it based on that. I once ran at a street car event against a tubbed 8.8 second vehicle that came in on a trailer but it was in the street class because it had an ET street on it and a license plate - lol street car my asz. GTFO with that line of bull - I hate that crap.

 

to not shift or shiftonly once you need an enormous stall converter and an AUTO

 

the only thing i have thought about doing with our stock trannys is going 1 2 3 5.


my 5th gear pulls like crazy, i try to get in it as fast as i can. i have yet to try it but might next time out to see what happens.


the second gear launch is kinda funny, maybe we could all have a B B Q on the clutch after your run...

 

or smoke a ham, hmmm...

 

WTF?! Did Jeremy just say he wants to skip 4th gear? Bro lay off the posting when you hit the crack pipe, yoru gonna lose any credibility you have by saying that $hit. Whats wrong with your 4th it doesnt pull or something? If you did 3-5, you would be in 5th at 90mph, which would be 15-20mph down on where 4th would land you....

 

I'm with you Alberto, I saw the 3rd to 5th comment and went .

We may eventually set a new record for misinformation posted in one thread. Maybe we can combine that with what "1fish" suggested (starting in 2nd gear) and we could go 2,3,5. This way you'd only have to shift twice (assuming your clutch was still alive when you went to pull 5th).
