ok welp today was the first time i've drag raced the 8

Air temp average 45-51 degress

upgrades : nitto 555 extreme zr's, simota carbon fiber intake

tire pressure : 40psi *i wanted it to be just like on highway*

run 1:
R/T: .151
60': 2.339
1/8: 9.837
1/4: 15.079
MPH: 92.45

Wheel hopped a lil and then stayed in 3rd till rev limiter never shifted into 4th

Run 2
R/T: .114
60': 2.353
1/8: 10.020
1/4: 15.371
MPH: 91.25

spun on launch, than tried shifting into 4th but obviously that didn't work

Run 3
R/T: .101
60': 2.371
1/8: 9.807
1/4: 15.050
MPH: 91.22

Just a lil bit of hop but felt great and i hit rev limiter in 3rd again guess thats the way to go

run 4
R/T: .432 i was sleeping
60': 2.519
1/8: 10.204
1/4: 15.519
MPH: 92.86

well i wheel hopped like crazy than the ABS light and brake light came on so i kinda freaked and i shifted into 4th so that run was a waste

also i'm a fat guy crushing the scales at 330lbs so i'm sure that hurt

what do you think about times good, bad average what? gimme some info, tips, tricks, etc

well i think they are good. I mean no diss you said it your self your what 330lbs thats like two avreage skinnky kids like me. So good times.

I think tire pressure is way too high if you want to try to get some grip off the line.

no offense taken i know i'm fat and i don;t mind it i'm workind to remedy it now but i am just curious if my time are around everyone elses?

Not bad. I just dragged my MS6 today. Left with a huge smile on my face. :)

I would think you'd get better times if you fully disable the DSC (hold down for about 10 seconds).

You can't say that without stating your time :nono:

LOL ok ok.......
I'm car #100 :cool:
My best 2 runs of the day!! (http://www.mazda3forums.com/gallery/displayimage.php?pid=4930&fullsize=1) :whip:

Here are my other runs.
My slower runs (http://www.mazda3forums.com/gallery/displayimage.php?pid=4929&fullsize=1) :(

Congrats on the wins.

i don;t have dsc or traction control what are good times in this car, plus i had plenty of grip i wheel hopped not spun plus i'm not a drag racer cornering is my passion hence choosing this over SRT. i thought like 14.5 + was average in this car

I thought that too. Didn't someone do a 14.2?

ok well i thought people were raggin on my times i thought it did pretty damn well i wlaked a non turbo supra i was proud

dude... 0.1xx R/Ts? Thats freakin insanely awesome.
I had a R/T of 1.2359 and got 15.4210 @87.69 (I was shifting into fourth, next time I wont heh), this was on street tires @28 psi.

14.5 seems fairly common for mag times, but the RX-8 for whatever reason rarely runs those times in the hands of its owners. Your times are pretty average, I've seen at least 3 RX-8s run at the track (could be as many as 6) and not a single one broke into the 14s, at least one of them had some boltons as well.

since when did they start subtracting 0.5 sec from the actual reaction times?

Polak's 14.58 is still the fastest non-magazine time I have seen. I'd say these are decent times.

15.0 is good for your first time! That's my best when my car was stock.

I'm now at 13.1sec with the help of a small Greddy turbo/ interceptor/ drag radials/ some weight reduction.... blah, blah, blah.

thats the time the ms6 are getting in my country 13's

for your firts time 15 flat its a good time, you should lower the tire presure to get more grip

I am by no means a drag racing expert but here's a few helpful tips for your next time:

1. First of all, your 60' time is very important. This is were you make or break your ET. The better you can get off the line, the better you ET will be period. If you bone your launch, the run is basically over if you are shooting for a good time. On street tires, a 2.0 60' is a good goal to shoot for.

2. Tire pressure. 40 psi is WAY too high for the rear (fine for the front though..think rolling resistance). Most people with full drag slicks run about 15-16 psi and with drag radials run about 20-25 psi. With your street tires, I'd try about 28-30psi.

3. Burn-out. Don't bother trying to get a good one. It's not needed with street tires. Make sure to drive around the water and then back up to give yourself just a bit of room before the lights. Then rev the car up a bit and just get a good spin to clean them off.

4. Constant RPM Launch. Once stagged, bring your car up to a pre-designated RPM and hold it there till the lights drop. At the same time start to pull up out the clutch petal till just before the engagement point. Once the lights drop, just release the clutch the rest of the way and put the gas to the floor. If you get wheel spin, then the next time drop the RPM by 500 and try it again. If you bog, go up 500 RPM on your next run. Keep trying this till you find that "sweet" spot RPM-wise where you get a good hook, probably with a tiny bit of wheel spin, and come out as best as you can. You judge this by your 60' times.

5. Shifting to 4th. This really depends on the power band of the car. If you are bumping up against the rev limiter in 3rd for more than 1-2 seconds, then you want to shift. Look at the power band (dyno sheets are the best guide) and you may see that if you short shift 4th a bit earlier it will put you into a better powerband range as you finish the run. Again, once you figure out the launch, this may solve itself as the beginning of the run will effect the end.

Hope this helps.

In regards to 1 and 4, it's a little different with the RX-8 and many high rev cars. It's really best to get a decent amount of wheelspin in the RX-8. Most of the faster runs I've seen for the RX-8 have had slower 60' times, losing a tenth in the 60' from a little extra wheelspin seems to gain you a couple tenths for the rest of the run.

who says they do?

who says they do?

Typically, reaction times start at .500 for perfect... meaning half a second from the time the last orange light comes on, which is also when the green one lights up. I don't really like the .500 deal, but they probably do it to avoid having to use negative numbers to show reaction times when people redlight.

TeamRX8 was just pointing out that Moonrover's .1xx reaction times are funky since they don't seem to be using the .500 system.

good for your first time out... with more practice you should be able to knock a 1/2 sec off

While I see your point, I just have to disagree. When it comes to mph, yes wheel spin will sometimes yield a higher number. ET, though, is all about the launch period. Improvements on the time it takes for the car to travel the first 60 feet down the track have significant implications on the final ET. As a general rule, improvements in the 60 foot time, are magnified by 2x on your final ET so giving up a 10th in the beginning is not a good idea. I did say that a good launch will yield just a hair of wheel hazing right at the beginning and that is what you want to feel when you find that perfect launching RPM.

In most cases you're correct, but in the RX-8 I've seen quite the opposite. High RPMs launches (even though there is more wheelspin) seem to yield better times in the RX-8.

We may be arguing semantics here because you are correct, bogging off the line (trying to launch at a lower RPM) will result in slower times but I'm just saying that blazing the tires and spinning through first gear isn't the best thing to do either. I like to call it hazing the tires right off the line but then hooking throught the rest of the run.

Tires gives best traction when they are right at the edge of traction circle so you should get a very little bit of screech and no more.

my best times came with a launch at 7500 close to 8 k for my 14.5 14.7 range if i launch at 5k to 6k i get in the 14.9 to 15.2 range

they switched to the .000 perfect launch last year so my times weren't that great actually


and sorry for the long response i kinda forgot bout this thread

ok when i launched i revved to around 4-5k and launched i didn't have any tire spin but i had a good bit of axle hop. i wanted to run the car just like it was normally setup. i think i more or less did things pretty standard for dragging. i wanna get my R/t's down some more though. i MAY do it again but its doubtful i'm more of a corner person / backroad stuff so this was just to kill some boredom on a cold day
