I was at the track tonight and I ran my car i have a 96 ls with Intake, Intake Manifold, catback fidanza 8lb flywheel ACT XTSS clutch and a 100 shot of nitrous, i wasnt able to do better than a 14.5, im pretty sure that its my driving. my reaction time was a .154.. Anyone that could tell me what the best time to shift is that would be great..i got a 14.5 at 101mph... my 60' times suck like 2.66 or something i dont remember.

So anyone that can tell me when to shift (what RPM) that would be great.

Thanks, JMAN

 

You'd probably get a better response here...

Get a header, cat and catback exhaust. Youll def free up some hp with these.

All i can say to help you out is to lower ur 60ft times and shift as fast as u possibly can. Reaction time doesnt matter.

 

It sounds like you're not getting traction. Try to work on that and maybe tuning. I think you can lower it another .75 sec.

 

dont worry about the r/t....get your 60ft down......2.6 60ft is whats hurting your time.....try getting 2.1-2.2 .....maybe your spraying at 1st gear...

yea im thinking traction. what rpm did u launch at?

 

you 60' time is murdering you. You could probably get high 13s if you could make traction.
Like someone else said, a high flow cat would help you too.
Although a 100-shot seems like a lot to me.
What tires/wheels were you running, and how were you launching.

Reaction time doesn't matter.

 

when i run at the track i was told not to let off the gas when shifting. just powershift the car. i noticed a decent difference in my times in my integra i had. from a 15.6 toa 15.3. i wish i could remember my 60' times. you should get a little difference.

 

wait so powershifting=not taking foot off gas to shift? what is the benifit? dn't mean to thread jack but im getting into drag soon...

i do not recommend this

i did this before.but ONLY to test drive cars at "mazda rev it up" event

wouldnt that **** grind the **** out of your tranny? at the same time overrev your engine ? For instance.....your in 2nd gear at 8k redline.....once you press your clutch in, it automatically goes into neutral position for that split second...wouldnt your rpm jump over 8k causing it to overrev? (8.5k+ rpm?) thats like that so called " double clutching right"?

If you were smart, you would shift about 300 rpm early so that you dont overrev. Fuel shut off is at 8300 i think on gsr so shift at about 7800 just to be safe. Shift as fast as possible. And to op: dont spray through first gear. You will probably be spinning the whole way through.

Ok .....I just dont get why people would do that.....second....I shift about 100 rpm earlier before my powerband drops....I dynoed my car and I loose power after 8600rpm, therefore I usually shift right at 8500.....why would i want to shift a few hundred rpm more if Im still creating a few more ponies before I start to loose power....? or are you stating that because people "powershift" they should leave a few extra hundred rpm so they wont overrev? EX: shift 7500rpm becuase "power shifting" will cause rpm to land on 8000-8200 rpm?

 

I am pretty sure you were spraying through first gear, bad idea unless you have goor tires(drag radials at least.

It is said and pretty true .1 off your 60 ft is .2 in the 1/4.

Power shift if you want to, but the reason mosy guys that drag race a lot dont do it is because it tears the hell out of the transmission. They all have the ability to with their computers, but chose not to to save transmissions.

 

your 60ft is a killer. get a traction bar. that'll help you some. full-race and lcon make great traction bars.

are you spraying in first? you're probably not getting traction if you're gonna spray in 1st. i think 1st goes by too quick to even spray.

i say practice your launch, get a traction bar and probably a header. that should help you a bit. i always just shift a redline. i'm hardcore

It's called rpm drop. You want to keep the car in the powerband when grabbing the next gear when the rpm drops. This is something that varies depending on gearing and the powerband of the motor. For example, my car stops making power around 8100 but I shift at 9K (H22 motor/GSR tranny).

If you want to be fast you must powershift.

Back on topic......the 101mph tells me the car is making good power however the 2.6 60' is terrible. Get it down around 2.2 on street tires and make sure you rev out all the gears and you should be in the low 14 second range if not high 13's on street tires.

 

101 should be good for 13's at least...

that 60ft time is terrible...dont spray in first gear, or dont drop the clutch at 8k...work on the driving and try out some drag radials

 

I try to launch around 3500 or so, ive been practicing with launching and stuff... i try not to spray 1st but the nitrous it activated by the TPS at full throttle so when i come off of the line i just floor it..its kinda just the first thing you think of is just to flloor it......

Im using Michilin pilot exalto a/s tires 195/60-14 on stock steel wheels.. . i lowered the tire pressure to around 25psi...

I cant seem to get the 60' times down....
Do you think if i just wait to turn the nitrous on until im actually in 2nd gear(hard to do because its a switch and its kinda hard to think of when on the line) would help with the 60' times?

 

Definitely do not powershift, you will most likely break your tranny (experience talking) and will probably make for slower times. Think about what you're doing. When you get to redline in 1st gear, you're going some speed like ~35mph. Now you powershift to second. You're still going ~35mph, but your RPM is still really high. The weight and momentum of your car is more than the power of the engine, so what happens? Your road speed forces the clutch to slipppppppp till the engine comes back down to the RPM that matches your road speed in 2nd gear. Stupid thing to do IMHO.

So you do have the switch mounted near the throttle body I see... just feather the throttle when you launch, wait till you hook up and THEN go WOT.

Unless your running slicks or DR's I wouldn't squeeze out of th hole or in first at all.

Experience talking, powershift if you want to go fast

 

do you realize how hard powershifting is on the tranny synchronizers? Do this much and you WILL say bye bye to some of them.

 

This guy is on the bottle. Power shifting on the bottle is a great way to damage an engine if the n2o is on a WOT switch(or dude doesn't know how to let off the button when he shifts).

The obvious answer to the question is 60ft time. Get it down to a 2.1(on street tires) and you will probably run something more like a 13.7 @ 103. I guarantee that's an easy mid-high 13 second car with a better driver.

thats what i was trying to state earlier......I would think your transmission would go out and slower your time...but seems like some people in here thinks it goes faster.....i dont know....I would just clutch in, gas out and shift real quick...

I never said it was good for your tranny. He was asking how he can run faster, not how to make his tranny last longer. He is already running a 100 shot and I really doubt he is too concerned about getting 100K miles out of that swap with a shot that large.

Running fast ET's and and keeping your car reliable is like oil and water.....they don't mix. Choose one or the other and have fun with it.
