EMS+light fly+ram air+UD pulley=quick RX
When I first came onto this forum I would always read how doing these mods had little effect on an RX8 so don't waste your money .
Well - you guys that keep saying that are wrong !
I've installed all of the above over the last couple of weeks and can say that my car feels very quick now. It just feels so much more responsive .
In 2nd gear from 6000 - 9000 all I can say is "YEAH BABY YEAH!!!!"
Sure it cost quite a bit to get it to this but I like the car so much I think it is well worth it .
Just to give you some idea I ran a 6.08s 0-60mph last week . That was before the ram air + UD pulley + air box mods & I still have to dynotune the EMS yet so there is more to come.
I have the before dyno (posted elsewhere) & will post it with the after dyno once done. I don't know that it will show big rwhp gains but whatever gains there have been have sure made this car a joy to drive.
I can't wait to line up a 350z .
Edit - was 0-100km/hr changed to 0-60mph

I'm pretty happy with all my bolt ons as well. Sure its not as quick as when it was turbo'd, but its much faster than it was stock. Can't wait to slap on the final gear and flywheel.

yeah, i was surprised the difference the Pullies make..everyone says that are worthless... my 8 deffintly pulls a lot harder then it use to...im not saying its the fastest thing on the road. but im a lot more confident now that my car can pull harder.. all i have is the borla exhaust, and the AP pully.. oh and the short shifter.... over the winter when my car is stored im saving up for the flywheel and the aem intake... no point in getting the interceptor. as i dont know how to tune and dont now anyone who is a respectable tuner.... or any tuner for that matter... so...

Keep us posted, The PCM is gathering information & will compensate for the changes. Thats why you'll read once in awhile someones always disconnecting his battery to reset the system.

I also just installed the ap pulley and deffenately notice a difference with it installed. The rpm's wind up faster it seems, as well as not having the lag associated when hitting the throttle, especially when the ac is on. easyer to get the back end out too

Notice that I didn't go for intake & exhaust - nobody seems to get decent gains from them so I put the money into an EMS.
I reckon by removing the vfad + the baffles in the air box + 1 screen before the maf+adding the RB duct , I've got as much as any intake is going to give me anyway. Also , I don't think adding a catback will give me any gains on top of the cat delete.
There is definately a midrange gain since doing pulley & duct - did not notice it the first time i drove it (probably because I was doing full noise testing) but now I can really feel a difference.

Just checked on the pulleys thread - those pulleys are 11% underdrive .
Agency power is 20% - so will be more effective (and cheaper).
Yes A/C will be affected but only noticeably at idle - see the pulley thread as we have been having a discussion about that very thing.

I suppose you could - will be a compromise on one thing or the other though.
Can give you some anecdotal evidence - people who have AP pulley rave about it - people who have other kits are not so enthusiastic.
If you want a high power stereo + great air con , don't get pullies.

well anyway, ya now that I think about it I'm definately interested in getting the Agency Power underdriven crank pulley... I don't think I'm one up for mixing and matching though... Is installing this pulley a DIY though?

meh i have a decent powered stereo (8" Kicker Solo Baric L7) maybe about 450w and i can sacrafice the AC just trying to figure out which pulley would be best. look like AP pulley is next on my list.. are you sure you can do this with basic metric tools? do you not need a special pulley puller?

ah man, a torque wrench?! Damnit... I'm thinkin about buying one at some point (I'm gonna remove the cat sometime...) but the way you describe the beating and the wood... That really turned me off... Could a mechanic shop install it? Cost range?

You won't be disappointed with the pulley as long as your not expecting huge top end gains. They use my dyno chart for their advertisement. A friend who has a lightweight flywheel and RB intake & exhaust took my car for a spin at the last GARX8Club monthly meet to check out my RP short shifter and he thinks my car has more power than his and that is with stock exhaust. He even mentioned that he barked the tires shifting into 3rd which is something I haven't been able to do (iI did need new tires though).
