RX-8 Gear Ratio!!!
I preformed a search but had know luck ,maybe some body can help me find out what the final drive ratio is on the RX-8. I know from my other experiences with Mustangs and F-body car's you can get alot greater buttom end response if you drop in a set of 4:10 gears. I beleive this would make up for the low torque rating and also making lauching the 8 alot easier at the track. I have seen reports of some mid 14 sec. runs on this forum, I beleive this was with the stock gears.I see no reason why a set of lower gears couldn't push the RX-8 into the low 14's, throw on exhaust, intake & a stage one then who knows the 13's can't be that far away. :cool:
|
I believe it's 4.444:1
|
you can get 13's with stage 1 alone
|
I could have sworn that the car had something ridiculous like 5.11:1 ??

Diff - 4.444 1st - 3.760 * 4.444 = 16.7094 2nd - 2.269 * 4.444 = 10.0834 3rd - 1.539 * 4.444 = 6.83932 4th - 1.187 * 4.444 = 5.27503 5th - 1.000 * 4.444 = 4.44400 6th - 0.843 * 4.444 = 3.74629 edit: sorry that is the japanese third gear. i cant find the US now but it is different. |
4.444:1
Drop a Canz Stage 2 with header, catless midpipe and catback exhaust and it'll probaly get mid (or low) 13's Put 16 inch wheels in the rear with slicks and you'll probably explode the tranny ;) |
:eek: 4.444:1:eek: My god thats a huge gear!!! Does any one make a larger gear set for an RX-8 maybe (4.755:1 +) this would greatly improve take off and 1/4 mile times. My goal is to get low 13's with out killing the tranny. so far my best is 14.6 @ 98.00mph only mods are K&N intake with RX-8 Store exhaust, thats not to bad I guss for a non turbo 1.3L. Any way thanks for the help.

stock RX-8 should hit 14.5-15.0... with exhaust n intake iw should drop to 14.0-14.4
|
US 3rd gear is 1.65:1.
|
I know this has been discussed before but I forgot, why is the 3rd gear different for US and Japan?
|
A pretty good start to getting your 13s would be a set of lightweight pulleys and a unorthodox racing lightened flywheel. Free up some HP and allow your already fast revving motor to rev even faster. Have done this mod to a few of my cars. makes a huge difference on some, less on others.

that sucks for japan, i love doing 3rd gear pulls!
