Who's trying to improve upon his kit? I think the thing is that some people have aftermarket pulley and wanted to know the effects of keeping those on and if they should replace it with stock. At least that's what I was wondering. I figured it would have a negative effect but I just wanted to check. Thanks to those who responded though.

likewise.. i have the pullies installed.. wasnt sure if i should uninstall them or not

maybe you all can bribe richard to produce a special pulley for the blower...

if you have read the thread he is quite fond of certain items

People, people the little hp the pulleys free up will be a mute point with this system

Pulleys, the SC has nothing to do with the WP, Alt belt. You can do anything you want with those. The AC belt will run the SC as well so it has to maintain the stock size lower pulley. This works because the AC compressor is disengaged by the ECU at 66% throttle. That leaves the whole belt to drive the SC when you are calling on it to do work.

^oooooo i like the sound of that

RP some people have an underdrive pulley on the main drive. Thats the one we are speaking of. Or are you feeding directly off an a/c pulley without the sc belt touching the main drive one?
Bump for my question--does your strut brace have a master cylinder support brace on it?

Everything drives directly off of the main pulley so it matters to everything. The main pulley drives the blower too. Even if he did spin the supercahrger straight off of the a/c pulley, which he isn't, it still wouldn't change the fact that the a/c is turning slower due to a smaller main pulley. The short is that if anyone wants to use a supercahrger, they will need to use a stock main pulley. If they absolutely must use an underdrive main pulley, they must be willing to accept less boost on the blower. While it would be possible for Richard to make a smaller pulley for the blower to compensate, it's just easier to keep a stock main. Keep it simple. Sell the underdrive main.

I hope this has not already been asked.

How close to stock is the intake sound? Is it a lot more aggressive like most of the aftermarket intake kits or did you try and keep it quiet like RB did with the REVI?

Is this a stock RX8 feature or something you have put in the flash ?

It should also be added that if you have something like the UR kit which has 3 pulleys in the kit, keeping 2 and throwing out the main pulley is also a big no-no...

I want the "jet turbine spool up" noise but only at WOT.

All other times I want the system to be stealthy and quite.

Sounds like you want a turbo

patrick_andraste

I like my K&N and RB exhaust. when it is sitting there at idle it is very quiet, and at low throttle as well. but I can pull into the school parking lot, blip the throttle and the distinctive sound lets my boys know I am there to pick them up.

RP - make a custom Axial Flow badge to fit the holes in the trunk

deppenma

nope no turbo for me..



I want RP designed turbine compressor noise

Punksux

I am not sure if the puerto ricans are coming out with a compressor

Very true they run off of ratios together.

Putting the stock main pulley on will overdrive the other pulleys like going to a higher gear on a ten speed the back sprocket goes smaller to turn the wheel at a faster speed (less distance to turn).

deppenma

beer was kicking in on that post

kristopher_d

If you have an underdrive main pully, you'll need to find a way to effectively overdrive the SC. Simply find, make, or have made, a pully that will restore the ratio that the AFE supplied pulley and OEM main pully have. Come on people, just because you're buying a kit doesn't exempt you from getting a little creative.

Will there be different ECU flashes for the AxialFlow supercharger? Since it appears they are going the flash route.

Will there be a more agressive ECU flash for a higher psi??? Maybe something pushing 8 to 9 PSI.

The AC kick out is standard thet do it stock.
The flash still controls the fuel and timing past the standard manifold pressure. It does not control the boost, that is controled by crank RPM and pulley ratio.
There will be an optional flash that one can use for track days when you are running 100 oct fuel. This is a track tune and keeps the fans on and the AC off. It allows for more timing and maybe leaner mixtures but I haven't really set that up yet.

As for an update, the flash is working in a car right now and being developed.
We are finishing up on the new stator tooling next week, we hope.
(Sometimes tooling needs to be built a few times 'till it's right)
And I still haven't gotten to the strut bar.
We are out of shifters and we need to run those real quick. So they get slid in about now.

Thxs for the update. please include master cylender brace with the stut bar

sosonic

My understanding is that you guys are going conservative on the boost. Its appears there is a conservative setup and a track setup.

Will there be something in between? I mean a setup that would be in the 8 to 9 PSI range, as oppose to the 4 to 6 PSI range. A setup that would push the limit of performance for a daily driver street car.

I think he just answered that in his last post... that'd be controlled by the pulleys not the flashes
