Sorry, no pics. New Supercharger kit for RX-8 shown at SEMA Show. Claim 260ps at the wheels at 4.5 psi on 100 octane fuel. Runs on stock ECU and stock injectors. Apparently the Presdient of Power Enterprises tuned the computer for the 787B, so supposedly they know what they are doing.

 

Forgive my ignorance, but why would you run 4.5 PSI and use 100 octane? It seems to me they should try to make power on gas that is readily available. Good to hear there are more options coming to light though.

 

Do you have a link by chance?

thats their website- the US place is near Racing Beat. Looks like the do centrifgal SCs

 

Oh more stuff.

- January 2006 release
- Price in the high $3000s

 

I would be surprised if it was that cheap. Their kit for the 350Z, while very nice is like $7500 (while everybody else is like $5000-$6000). Would be nice to have more options. But you are right what is with 4.5 psi w/ 100 octane fuel ?

 

I think they are using 100 octane fuel to slightly inflate their number. they are using 4.5 psi because thats what will be what the kit will be set with.

 

I don't find much interest in a centrifugal unit, personally. It just won't give the grunt down low of a twin screw or turbo...

 

High 3000$s seems reasonable if no ecu upgrade is needed. We have 98 RON in Europe, so power figures should stay close to 260 ps at the wheels... the car should be a total blast!!!

 

isnt 100 octane in japan the same as 93-94 octane in the US..different calculation methods or something?

 

Yep. Same stuff.

 

California highest I can ever find is 91 octane.

 

I use 93 here in Georgia

 

higher octane doesnt give you more power so forget the octane. probably you will need to use the highest octane normally available in your area to prevent timing retard from knock. thats all that means.

 

I think the 100 octane fuel is just for safety margin. Remember, they are using stock ECU, which means they could have no control over the tuning. Putting a safer octane is just smart when you're dealing with no tuning control over a boosted engine. The way the ECU dumps uber amounts of fuel at the top end, I can understand why 4.5 psi doesn't require an ECU tuner.

 

100 octane fuel by itself won't give you more hp. it gives you detonation resistance (so you can turn up the boost). That is why 4.5 psi is strange. Hell, with 100 octane I would try 10-12 psi with my Greddy.

 

Oh ok. I just always hear about some supra did such and such hp on 100 or 103 or race fuel.

 

NOT a centrifugal.

I was at SEMA on Tuesday. Saw this install. Looks Clean.

It is a standard ROOTS blower. Should go a long way to flatten out the torque curve and provide INSTANT response. I posted a pic here:

Also, at another booth (TurboXs) there was a new complete fuel and timing computer for your RX8 that you can program with your GameBoy. Put these two separate items together and you might have something...

nice install, thats clean. Hopefully it is priced pretty competitively

This is good, bring the options on

 

I wonder if they just have the stabilizer bar off for display purposes...

 

Yes 98 RON in Europe is about the same as 92-93 Octane in the States. 100 in Japan is about the same as 94-95 in the states.

Higher octane gas just means it is less likely to knock, preignite, etc. than lower octane gas. The energy density can be slightly less or it can be slightly more than low octane gas depending on the mix. They could use Xylene to up both the energy and the octane or they could use some sort of junk fuel to only raise the octane but decrease the energy.

Above and beyond the octane rating there is supposed to be some sort of unpublished "driveability index" that the refinery has to meet with all of the gas they produce.

In short, octane rating doesn't mean a whole lot; and if you ever want race gas it is best making it yourself. Mixing 67% quality 93 octane with 33% Xylene will give you both a high octane mix (roughly 100) that has great energy density as well.

Yeah it looks like everything would fit below it.

I have to say that install is a real bolt-on. A water to air intercooler would be nicer but given the location that intercooler would probably work fairly well.

Brian,

Lysholm are very similar to roots-type and are often considered more efficient. Is there a reason you don't like them?

Honestly, I wish that kit was a Lysholm and not a roots (presumably Eaton).

-Mr. Wigggles

 

this kit look alot like thwe knight sports SC kit

 

Bump

 

yeah why would you favor roots over lysholm when the lysholm is more effecient version of the roots s/c? weird. Nice and clean...
