As you can see my best run was run 9. I started to get into a groove and it was improving my time, instead of dropping the clutch and getting massive wheelspin I started feathering the clutch out. I would rev to 4 grand and lightly let it out anything else and I got massive wheel hop. Then as you can see after run 9 I started to mess up. I'm probably gonna go back down to 19s and get wider tires. I think if I had the stock 18s on I would have gotten maybe a 14.1 or better.

dtorre

what track was this at? Hey if you guys want to have our meet at the quartermile track for bragging rights im down

Terrance26

Its Academy Raceway in Temple maybe about 20mins from Killeen. By the way you still got that midpipe dtorre let me get it off of you.

army_rx8

i would put the stock 18's back on...those 20's effectivly change your gearing a lot. making you accelerate slower. no idea how much b/c it's entirly to late for any calculations..lol well looking up the formula mostly

army_rx8

oh and weight of them played a roll too...i believe the stock rims are 18 lbs.....and those are 26.5

that's a 8.5lbs difference per wheel...let alone what the tires weigh..harder to accelerate the wheels..since they are bigger (larger diameter) and weigh more.

army_rx8

hehe other than that...glad you got a lot of runs in..it's always fun going to the strip when no one is there

Terrance26

I am definitely gonna find some lighter wheels.

army_rx8

hmm looking at your trap speeds they are a little slower than i would think running FI (i would think you'd break 100+)...but it'd most likly the rim size playing a huge roll in that

army_rx8

and smaller i hope lol i would give you mine..but the front 2 don't look so pretty after the head-on accident i had. LOL

Bloodroz

well I might be buying some 18X9.5 with some 265/35s on it ill let you run on em' and see if it helps any... IF/WHEN i get em'

army_rx8

^oo that'd be nice....should hook up pretty well with that wide a tire.

what type rims/tires were/are you thinking about getting?

dillsrotary

in addition to the tires, a proper tune might help break into 13's

Terrance26

Yeah the tune is coming by the end of december. Trying to find a good rotary shop in Texas, Rotary performance is booked up and thats the only good rotary shop that I know of in Texas.

dtorre

Hey I still have the midpipe...can let it go for $160....exact amount I need to fix my window =P

Terrance26

Sold!!!

I haven't been to the dragstrip since I bought my RX8. It's almost bone stock except a CAI but that doesn't really do much at all for 1/4 mile times I reckon.

Last time I did a 1/4 mile was on my 125 Shifter Kart. 12.8 seconds at 117 MPH trap speed. Pretty much pegged out at 117 well before halfway.

Last time I ran the shifter in an autocross the top speed was about 85 MPH on the course with a 50 second lap. The next best car with fenders was a D sports racer with a 13B that turned 51 seconds. The best time from anything with a licence plate was a fully tricked out Porsche 911 running a Modified class with slicks turning something in the low 54's. The fastest time went to a Formula SAE car running in "outlaw" form with a former national champion shifter driver barely breaking the 50 second barrier. Had he driven my shifter kart he probably would have dropped another second off my lap time. The best RX8 turned a mid 56 taking second fastest time for the stock classes. This course was a good balance between power & grip so the RX8's superior handling made a huge difference. There was a turbo RX7 that showed up but the driver was slower then even I would have been.

Bottom line is for the price of a turbo you can go quite a bit faster at the track without risking the durability of your daily driver.

Terrance26

My car runs just fine. I have not had any problems with my car before or after the turbo. It runs like stock with boost. So basically what you are saying is that I should go out and buy a go cart, no thanks. I drove my car to the track, had about 12 runs almost back to back, between some runs I stopped for a min to let the car cool down, then drove it home. And then guess what I woke this morning and it started fine. What I have learned from these rotary engines is that they are quite strong. I know when I was running nitrous I detonated my engine maybe 3 times, not just a small intake backfire I'm talking about the intake plenum blowing off, the accordian tube blew to shreds and the filter box exploding blowing the clips off and shredding the filter. I replaced each of those items 3 times, like they said you have to pay to play. After I put everything back on it started right up with no problems each time, then I took it in for a compression test and it passed. then I went ahead and installed the turbo. Maybe your right I maybe risking the durability of my daily driver but I can't stay stock and that went for every car I have ever owned and ever will own.

dillsrotary

so you're saying in the past 50 or so years of guys upgrading their vehicles to go faster in the 1/4 mile is a waste? thats the essence of the 1/4 mile, adding parts and skill and time to a daily driver. every guy wants a car that he takes to work and on saturdays runs mid 11's.

CosmosMpower

WTF, only a 96 mph trap with a turbo? I thought those were times for a bone stock RX8 or something like that. Are you running very little boost like 3-4 psi or is something wrong with your car? I know a lot of people were getting 14.5 @ 94.5 mph bone stock. There's no way you only picked up .2 of a second and 1.5 mph with a turbo kit.

Also your 60 foots should be in the 1.9 range not 2.2. I pulled 1.7's in a fwd open differential civic on drag radials.

Steve Kan is in Ft Worth. If you dont know who that is... you need to ask somebody.

Swerve76

He's running 20" wheels...

Terrance26

Like I wrote before I have 20s on WITHOUT drag radials and the turbo is untuned, running stock greddy boost. I have not perfected my launch either, thats why my 60ft is that bad. If I launch wrong I get massive wheelspin all the way through 1st straight into second. And I have only read about 1 person(polak) That got a a 14.5 that has proof. Once I connect the car is like a sling shot even with the 20s on. Launching is hard with this car and its even harder with a turbo, I'll tell you what lets go from a roll on in 2nd and see if you can keep up with your stock 8. I have left plenty gt mustangs in the dirt from a roll on, its just perfecting the launch.

mysql101

Terrance, do you have a boost controller? That makes a large difference too. As would going for a 3" exhaust and a catless midpipe.

I think some of these numbers give people the misconception that the GReddy kit is slow. The RX-8 is significantly faster with it. No comparison.

CosmosMpower

Yes I understand you're on 20 inch wheels but i'm not too worried because your trap speed still tells the story. And if you have a bad launch out of the hole it doesn't affect your trap speed much, in fact sometimes if you pull a GREAT launch with tons of stick at the start your traps can actually suffer 1-2 mph. A few magazines have actually gotten a mid 14 @ 95 mph so it can be done, maybe not in a touring/grand touring model but it can be done.

Either way 96 mph is pretty dissapointing for a turbo 8 any way you cut it. It may be the wheels or the heavy stereo or the driver but run what ya brung. I'd be happy to race you from a 40 mph roll in my bone stock s2000 if you like, I know it traps 100+ already, beating mustang GT's is no big feat. Or better yet come out to an autocross next season and we'll see how fast you can be in street mod class.

P.S. the turbo civic I had was untuned as well it only made 176 whp 173 wtq and ran 8.52 # 83.5 mph in the 1/8 mile and it was FRONT WHEEL DRIVE with an open diff not rear wheel drive with a limited slip. I could pull 2.1 60 foots all day on the factory 185/50/14 firestone all seasons.

CosmosMpower

I wouldn't disagree, any car with a turbo kit on it is going to be faster. I'm just very surprised that the numbers say what they do. I figure the 20 inch wheels with 6 pounds of unspring weight per wheel and i'm guessing 2-3 pounds more per tire make a difference. I also think that having a sunroof/leather model car makes a difference in weight and when you add everything up it's probably good for at least .5 second ET and 2-3 mph traps. My guess is a base model with the greddy kit on factory wheels/tires is good for a high 13 @ 100-101 on a good day.
