Went to the local 1/8 mile again determined to get at least 9.5.........well i got a 9.2 and a 2.1 60ft......sooo much better than the first time.......with this time what 1/4 times should i expect.......

nice

i wish i had a vid but my wife was at work.........

damn, i would want to see that.

by comparing other 8 low times i think i could get a 14.3-4 out of that.........only mod right now is the ap pulley

"its not as much about the car, as it is with the driver"

just imagine what times i could get with chets secret mod.........just imagine:bootyshak

hahaha

with this time what 1/4 times should i expect.......
The most widely accepted conversion formula I've found is to multiply your 1/8mile time by 1.56. This'll give you a 1/4 mile time of 14.42. Nice driving! :icon_tup:

What were the temps like? What were your launch rpms? Any axle hop on your launch?

72 degrees..........launched at 7000 feathered clutch..........no wheel hop....32 psi tires....i heated the tires real good.........

Nice time for such warm temps. 7K launch is pretty high - was the vht at the track really sticking?

vht????? im a noob all i know is that when i dont heat up the wheels i spin like crazy.........the first time i went i got side ways shifting into second

keep in mind that peak torque is at 5.5k. 7k may be overkill

yeah but when the wheels stop spinning rpms fell to about 6k

good point

vht????? im a noob all i know is that when i dont heat up the wheels i spin like crazy
It's the black stuff they spray at the starting line. Gives your tires better grip when coming out of the hole.

ohh.........i know that my tires are alot stickier on the street vs the strip..........its seems the only way to get traction on the strip is to spin the tires prior the run.......

not bad man, you gonna run again after your intake gets there for a comparo?

9.2 thats impressive i had a 1/8 of 9.6 and a 1/4 of 14.8 with a low compression engine

yeah im gonna go again after i get my intake and midpipe istalled...+15hp.....maybe if i get lucky......i can pull 8.99........id have to drive perfect......but i think it can be done......i know i can get a lower 60ft time......i got a lower 60 the next run but i missed shifted into second......still ran a 9.4 though

if you are running on the stock exhaust don't expect +15 hp from just intake and midpipe... I've been down the same route man, trust me, don't expect that much horsepower and just be happy to gain anything you can. You'll feel a lot better about your investments.

I think both of those modifications will have more noticable effect in the higher gears. as per really significantly improving your 1/8th mile time I would really recommend saving your money and getting a lightweight flywheel like the fidanza. If you stay NA the stock clutch is strong enough to take it easily, and you will make a much more significant gain in the areas which you wish to improve. Just givin ya some food for thought.

thanks........i thought 15 was conservitive for a catless pipe and typhoon v.2

well it really does depend, however for the most part ( and this does vary depending on the specific car and brand of parts) a REAL 15 to the wheels with catback/intake/midpipe/flash is about right. I can tell you this, that k&n will make you feel your 3rd and 4th gear are definitely improved. It had that affect on me driving my friends with it equipped, although I never saw any dyno's on real (non butt-dyno) gains. Just be ready, that fuckin thing rips and your 8 is gonna have a much differrent personality!

eh, with the flash you could be higher than 15 hp. the RB street flash has a gain of 7.8 hp. who knows with the race flash

eh, with the flash you could be higher than 15 hp. the RB street flash has a gain of 7.8 hp. who knows with the race flash

Race flash actually makes almost exactly the same power, which I confirmed with them on the phone two days ago before I sent out my ecu. As I said before how much you actually gain is going to vary especially with this car. No doubt +15 is reasonable and attainable with those modifications if everything is in good shape.

Nice run :)
I haven't had a chance to take mine out to the track yet, that gives me a baseline to shoot for.

thanks........good luck......... the first time i went my best was a 9.8........but that was my first ever drag run in any car...

Something's wrong, my 92 Sentra SE-R with intake/header/17 degree timing bump ran a 9.0 @ 73 mph with a 1.8 60 foot a few years back. Are you really high elevation or something, the 60 foot looks good and E.T. is good but the trap seems way down. It's been a while since I've been to a strip though.

no........its just that in an rx8 1st and 2nd suck.......you dont stay in your power band untill 3rd gear so the 1/8 track is going to be high but you can still pull mid 14s in the quarter.........my friends magnum rt runs an 8.6 in the 1/8 but when we race on the street i catch up and pass him as soon as i get into 3rd and fourth gear.....magnum rts run mid 14's in the 1/4 as well.......most times ive seen for an rx8 in the 1/8th is high 9s to low10s.....so nothings wrong its just that every car is diff......the 8 is a high end car

2nd should pull harder than 3rd.

im just saying that yeah second pulls harder, thats natural due to the gearing of cars......but in once you hit 3rd you are in your powerband the whole time so the eight accerates better than other cars with a lower power band that have similar 1/4 mile times.....like a wrx they win every time low end but on the highway the 8 will win

true.

Nice run, man! :bowdown: Your 1/8 trap speed is lower than I would expect, but thats because your 1/8 ET and 60ft shows you were driving the shxt out of it!! Interesting you said that you hook better on the street than at the track. Must have been a test a tune night and they don't prep the track the same... that actually may be an advantage for the RX8, so you can launch at a pretty high RPM and not bog. In any case, good job! Keep chasing it, and I'd really like to see what you can do 1/4 mile!

What was your 60ft on the other run? If you got a 2.0x or 1.9x, I'd really be impressed.

the next run got a 2.11 60 but misshifted in 2nd ended up with 9.4 on that run.............yeah i think thats what it was "test and tune"

oh yeah i got a question what does the 1/8et mean........forgive me as i dont know much about drag racing.....i just know to go when the light turns green.....thats why my reaction time is horrible

I don't know if I quite understand your question, but your 1/8th et is how long it took you to go from a stop at the light till you cross the finish line.

Okay, so I'm not a guru compared to some, but I'll share what I know. ET is simply Elapsed Time. On your slip, you see 1/8 ET, 1000 ft ET and 1/4 ET... just the time it takes for you get to that distance. Trap speed is the MPH at those distances. The relationship of those two numbers is important to understand to tell how well you're doing compared to how well you car doing.

In general, ET measures how good a driver you are and how well you and your car can 60ft (launch). Trap speed (MPH) measures how fast a car you have and how much horsepower, even if your traction limited.

There are cars that are setup to ET very well and have sucky traps. There are cars that throw up some INSANE trap speeds and not ET worth a shxt for the MPH they post.

In the quarter, a stock RX8 can trap 95 MPH on a good run. If you trap 95 MPH, you can be sure that your car is making good HP, even if you don't ET 14.5 seconds. Mod it, and you'll increase the trap. Okay, so by trapping 95 MPH, you know that your car is capable of a 14.5, but maybe you haven't driven it well enough to get that ET, and you have to interpret your time slip to figure out where you can do better. Is it the 60 ft? Are you short shifting and missing out on power on the big end (the last 1/8 mile of the 1/4 mile)? You have to compare runs and slips and figure out what works.

So, "anybody can bang gears", as a friend of mine says who has 500 drag racing runs under his belt. The key is a fast launch technique, and shifting quick, not necessarily hard, at the right RPM. Fine tuning that can take a while but it seems like youre doing a great job so far.

Oh last thing about your reaction time....
It DOES NOT count in any of your ET's on the slip. It simply measures how long it took for you to launch after the green.

The lights are spaced .5 seconds apart. You left .8049 seconds after the green.
The trick is to leave when you see the last yellow light. If you actually see the green light, you waited waaaay too long. See what I mean?

If you red light, it's no big deal on test and tune night. Just delay a fraction of a second more after you see the last yellow until you get a good reaction time.

Yeah, I need lighter tires for 1/4 miles, I'm currently in the 17s with 19 inch rims

oh yeah i got a question what does the 1/8et mean........forgive me as i dont know much about drag racing.....i just know to go when the light turns green.....thats why my reaction time is horrible

Reaction time has nothing to do with your E.T.
