Air gets too dense, boost controller responds by reducing psi, in order to keep the the number of moles of oxygen from growing beyond what your car and fuel system is tuned for. Some day..
A density sensitive boost controller. Now theres an idea. If charge temps were colder than normal (IE, cold day) it would reduce boost to compensate for the denser air saving your vehicle from the dreaded, cold morning boost spike.

When you purchase the RX-8 turbo system you can be assured you are getting the best turo system on the market.We are so confident about this that we offer a full one year warranty on all parts included in the kit.

I'm sure feeling great about getting the best TURO system on the market. whew, i was worried there.

Richard, may I hold on to your engine analysis document? It's really interesting, especially when your simple algebraic equations put my thermodynamic relations to shame.

Haha, I have yet to visit that forum but from what I'm hearing, maybe it's better that way? Anyway, Richard that document is actually pretty easy ro read and understand, puts Shelleys posts to shame :p . Thanks once again for helping a poor freshman who can't understand much of the physics that are talked about on this forum.

Density!!! That was the word I couldn't think of! That's funny because I just watched "Back to the Future" and in one scene in 1955, George goes up to Lorraine and says "I am your density" rather than "destiny". That word has been stuck in my head all day. Just not in this context.

I talked with Tim today from Speed Force and here is what he told me.
They have spent 6months on this turbo project and will have it ready for sale next month (Nov).
The ratings Tim has told me are 350hp Flywheel 300 rwhp at about 8000rpms
The ratings Torque are 300ftlb Flywheel and 250 ftlbs at the wheels, at about 4500rpms
Tim has told this will all be posted in the next few weeks. I hope this is all true

Update Guys,
Just talked with Tim from SFR. Tim said timing of release is still Nov.
They are just finishing the treaking of the Rick Shaw ECU. They will be posting Pics and dyno's very soon.. HP numbers still as I reported ..
One thing came up Guys, Tim has said the weak link just might be the Plastic intake, Tim said that the plastic actually expands as the boost increases and
contracts as boost decreases..
I bet we are going to need a New intake to take care of this, for those who really want to have FI system.. That's my two-cents..

2) I don't see how it is an actual problem (how much volume could the expansion possibly represent?)
3) I can see how this is easily solved (glassing)
Please elaborate.

1. why does it ballon and not break?
2. does the whole thing balloon or just one area?
3. why does it balloon at all? pressure? heat?
4. did the aussies note this while building the turbo one? what did they do about it?
and several others

Hi, I just talked to Cam from Pettit about this expanding intake under boost and Cam has said he has notice this too. That's why he's coming out with a new intake for his SC kit by beginning of the year.. Well guys it does look like there will have to be a New intake if we really want to boost our 8's and have it be reliable..

I think he is referring to fiber-glassing the intake to prevent leakage and expansion. I don't see how you could be getting much expansion though, the plastic is extremely hard, and at most you would only be seeing IM pressures of 8 - 10 psi. I fail to see how that intake could not hold 7 psig. Maybe the plastic is to hard, making it crack under even slight expansionary conditions. After seeing plenty of boost make its way through the top of an LS1 though, I have gained a little more faith in plastics.

Stuck in a love triangle
I knowthat most of you following this thread wont care but I called speedforce and askedthem whether or not the turbo kit wasalso being developed for the automatic Rx8and they told me it was exclusively for the manual Rx8. Bummer forus auto owners.

$5200 turbo setup + $1300 for the Rick Shaw ECU/Fuel management unit is OK (+ I would drop the extra $600 for the ball bearing turbo, but I already have the hi-flow cat unit from SR Motorsports so I would not get the cat-delete pipe). Anymore than that and I don't think I would get it. I am pretty close to Santee too (I believe it is near San Diego), I would see if they would want to do the install and play around with another RX8 I have friends in SD I would spend a week down there. Oh well, let's see what they come up with.

I saw that idling video a while back, so um, repost? Nah I'm kidding. I did see the video, and I've been quite perplexed as to why the engine started smoking by the end. Cooking oil? Oh well.
I think SFR and SSR use a T4 turbine, but I'm not sure. I think you can get away with such a setup, at the expense of your warranty. Like I've said before, turbo systems will last as long as the owner wants it to, meaning the car needs to be properly maintained.
Lately, since reading about Autorotor twin-screws from Kenne Bell's webpage, I've been affixated on such a compressor. However, none is really better than the other. It all depends on the user. Personally, I'm still gunning for a GT35R turbine, and that's where it stands.

Waaaaaay back then it was stated that the smoke was coming from a wire loom that was too close to heat and started to melt. Something to that effect.

Hey Rotoman.. or anyone for that matter.. do you have any updates on this project or Pettit's? The last update we got was just over a week ago and the November completion date is fast approaching...
thankx...
Oh... the only update I have is that SFR will be happy to show you their turbo kit if your in the area... Maybe someone local to San Diego will take a road trip. Please dont forget your camera..

I dont understand why they even give completion dates now. They should just hold them to themselves... SFR has already given out at least 3 and missed them all.. They look like amatuers to me. I am sure they are not... but whatever.. It just doesnt look good.
