Great night for drag racing at 51 degrees. 2 other rx8s showed up a stock one and rote8 in his pettit supercharged 8 but couldn't make a pass because of his problem with the methanol injection.

I was the stock rx8. Pulled a 15.03 at 92.06 mph. My tires are bald and I was spinning all through first and second. When you guys run do you have dsc on or off?

 

Off.

 

fd 5 speed trans? how u do that? how hard was the swap? this has got to be the fastest NA RX8 PASS EVER....kersh is gonna be so pissed lol

 

what was your launch like?

 

I have a base model but i would turn it off.

mazsport did it i don't think it was too hard even still have the stock driveshaft

 

Seriously???

I would think that 13's would be very doable with just bolt ons, gears, suspension and tires...but, I've never tried, so I might be talking out of an orifice other than my mouth...

 

yep - fastest i've heard of .

Well done cfl

 

I ran with it off need new tires though. Whats the average time for a stock rx8?

 

heres my timeslip

Good job cfl didnt realize how fast that actually was for an rx8 when you told me

 

what size tires?.....btw 2.0 60ft has alot to do with the great time....

 

what's scary is that with a slightly quicker R/T.. it would have been even better.

 

r/t doesnt mean anything, unless its head to head..the timer starts when the car moves......whats scary is that you should know this.....lol

 

having never drag raced my car I guess it makes sense.. the drinks didn't helping

 

I'm on kumho ecsta mx 225/40 stock wheels.. launching around 5500 rpm

 

wow,

you were in the appliance direct lane! to funny..

btw, very nice times. what were you using for tires and how did you launch?

nice 60 foot time.

sorry i needed to hit refresh before i posted. asked twice and answered.

good job. btw, do i know you? what color is the car.

beers

 

what kind of ratios do you get with the 5spd.....do u think thats what made the diff...

 

OK...that's the "missing link"...when I first looked at the modifications to your car and your trap speed, that's what got me thinking that you should be in the 13's, no problem. But, the tires (and the 60' time) explains it all. Given that you're nearly 100mph in trap speed, with your launch and suspension (shocks, disconnected front sway bar etc.) optimized, you could go as quick as 13.6-13.7, based on normally used ET formulas (that's ASSuming that your RX8 is right at 3100lbs with you in it). What is also kind of interesting is that using the same equation, it would give your horsepower at right around 240 at the crank...which makes me think that the '8 doesn't make the factory rating, stock, as your car is obviously much stronger than a stock RX8.

 

did you account for the different ratios on the 5sp?

 

very nice times!!!!lets see some 13's next time.

 

No. I just used the "old school" formula for calculating hp from trap speed and then backed into the "potential" ET...it isn't 100% accurate, by any means, but is a tried and true means of estimation and gives good information.

 

i keep telling everyone that headers, intake+rb duct, full turbo xs exhaust give some serious horsepower gains. does anyone believe me? nooooo. well now maybe you guys will.

and lol chance, no im not pissed. he has the 5 speed fd tranny. the nice thing about that tranny is that you dont have to shift into 4th right at the end of the 1/4 mile. i trapped 97mph, had i not had to shift to 4th, 99mph is totally plausible. believe me, i looked at that transmission when mazsport had their direct drop in rebuilt fd tranny. it only cost $3000. :/ mazsport posted a 14.3 with their fd tranny (and a 2.1 60' i think) a long time ago. oh, and another benefit of that transmission? at 80mph the rpms are 3500 afaik. better gas mileage to boot.

cfl, throw some 245s on there and you can cut that 60' down a few more hundreds. you should be able to hit 13s np.

crh claims that a lightweight flywheel is good for reductions measured in tenths. his flywheel and pressure plate are on my list of mods.

mwood, are there real gains from disconnecting the front sway bar?

 

and you dont have to worry about breaking it.

and sways. for front to rear transfer, not so much...

tire pressure and shock valving is all that is needed..

beers

 

very true.


i dunno, i kind of disagree about tire pressure. i can run consistent 2.00 60' @ 32psi.

at 25psi my 60' goes to ****.

maybe im just not used to 25psi.
