That's reasonable.

how about some pic's of the exhaust and headers?

I agree with olddragger. This car most definately has a high 13 second in her N/A. Tunning is key, tires are key, weight savings is key and the right n/a mods are key. Add all this with driver skill and you'll get the key that will unlock the 13 second door.

Okay to get rid of the wheel hop drop your tire pressure down to about 17 or 18 lbs, this gave me the best result to prevent wheel hop and increase tire grip. Second launch at 7,500, and make sure to feather the clutch, don't dump from a launch other wise it will result in too much wheel spin. Also someone mentioned it, the power band ends at about 8,450 rpms to 8,650 rpms I haven't found the exact number yet. So shifting at 9,000 is waisting time in the 1/4 mile. I used to consider my a good driver in the 1/4 mile, but after learning from drivers such as Peter Farrel and Sean Glazer you begin to realize factors that you never thought of before. So give these ideas a try on a stock RX-8 and you'll be damn close to a 14.5xx but it also depends on elevation, tempature, humidity, how much gas you have in the car. A lot to factor in, but again, just give if a try and I think you'll be happy with the results.

you better have an aftermarket clutch as the OE clutch will not last long being slipped

I can drop at 7000+ without excessive wheelspin, it's all in how you control the throttle immediately following the dump.

yup your right mate. it can be done. i bet that as soon as my car gets back from promaz ill post a video of me pulling a sub-14 run. Just launch it right, change fast and let it rev and you can get in the 13s..

I'll bet you'd be into the high 12s with a numerically lower rear axle ratio? With FI, 1st gear is too much of a stump puller, & you lose time on the 1-2 shift.

Good discussions. Wheres Charles Hill?

You didn't title your thread "Greddy turbo drag racing - low 13 sec." though, you said "Greddy turbo drag racing - 13.1 sec" (joke)

Sorry, sorry....Adrian_1 what is the name of that friggin song playing in that video u posted? i cant seem to get it outta my head.

Well done ants! Better get a proper time slip so you can take the Aussie mantle

Gtech is good if you compare it to an earlier run.

12.99 is a 12 second car - it has broken into the 12's. That is how drag racers work, it aint up for debate!

Cheers,
Hymee.

PS - 19 and an RX-8. I thought there was a law against that? j/k

I'm not sure what the limits of our NA Renesis is, but I hope one day to cut .5 sec off my times by cutting some weight on my 8 and getting some good NA mods.

I hear you all talk about this stuff and it makes me feel I'm missing all the fun, but right now my 8 is too new and has too little miles for me to start messing with it...I guess I'll have to live through your stories...lol.

well the normal conversion for weight loss, is for every 100 lbs you take out of the car you can gain 1/10th of a second in the 1/4 mile. So some ideas are carbon fiber body panels, (i.e. hood, fenders, and trunk lid) Pull out the passenger seat, carpet, rear seats, some interior body panels such as inside the trunk, pull out the sterio system, speakers, pull out the spare tire, switch to lighter rims. As far as performance goes, headers, 3 inch exhaust, ignition amplifier, air/fuel controller tuned correctly, intake, pullies, street port the motor, port the throttle body, polished ported intake manifold from Acosta, clutch, and a lightend flywheel, that'd be a great start and could possible take MAYBE, and I mean MAYBE take a second off your time. The reason I am saying this is because the Renesis is so well built from the factory to run N/A it's hard to squeeze a lot more power out of it. But then it could be more then a second, you'll have to try it out.

As far as running any faster then a 14.5 completely stock it's extremely difficult if not impossible. Even road and track couldn't pull off better then a 14.5 and they have professional driving their cars, and I believe the best they ever did was 14.53x. That's just my .02 cents

OK, let me revise my "hope"....I hope to take off .3 sec off the car...lol

The weight loss I am looking at is about 100 pounds but most importantly I aim to reduce the weight in key area's (rims, flywheel, and pullies (not underdrive since I hear that's not a good thing).

So, with 100 pounds of weight loss (reducing unsprung weight (I think they call it) on the rims, flywheel, pullies, etc) and gaining (finding) about 20-25HP more I hope to cut my possible 14.5's to 14.2's.

Is that reasonable?

With that said, have you seen the price for the Greddy Turbo now a days...it's CHEAP for the power you get, only 2.9K or so...but of course you will need the Inter-X which makes it too expensive for me at least.
