Hook it to a slingshot at the other end of the street.:p

That sounds awful interesting. As an unwashed in these things:

1) is a supercharger 'better' than a turbo, under what conditions, and why? Is it more compact, uses less power, etc?

2) this is the 1st for the 8 I've heard of, any idea why a they choose this?

3) is it to be avail soon, or just a prototype?

4) any prices, dates?

Thanks! Sorry if I ask too many ??, but it sounds so good!

Is the body kit onthe white one from Knight Sports? If so, who is carrying it in the US?

Jt-Imports

Yes its from Knightsports...

Your in Tokyo and you want to buy it from the states? Im sure I can think of a few people/companies that sell it in the US though.

Japan8

NO no... why would I waste money on an 8 in Tokyo when I could only make use of it on weekends? And that's only during the winter... during spring through fall I'd be on my motorcycle.

No, I'm seriously looking into moving back to the US... likely the Seattle-area and am hoping to buy an 8 in 6-10 months time. Know of any good jobs.. IT-related or car/bike- related for a fluent bilingual? :D

One thing to consider about the front fascia is, is it fiberglass? I am pretty opposed to fiberglass...

*OFF SUBJECT*

IT--you can get some pretty good jobs in Tokyo hehe

I work up in Tokyo actually full time at an import/export corporation.

*ON SUBJECT*
The bumper IS FRP. I dont base FRP like Fiberglass, I mean its almost the same, but it doesnt break into little pieces quite as easy..

I know... been doing it for 5 years here in Tokyo. But there are elements I hate... last job I worked from 10am to 11pm/12am in the office regularly and then went home to do teleconferences and check mail again... only to repeat the cycle again the next day. There are other things besides overtime as well... Japanese salaryman mentality... the list can get long. I am also feeling trapped in an engineering role, and I am a bit burned out...I want to move over to a more business-related role... i.e. Project Manager, Business Development, Marketing OR maybe just a different field entirely... get a BSME.

Here's a big one...would you want to invest money in a house in Japan knowing that houses and mansions only depreciate? Rent is expensive and a waste of money... A rock and a hard place...

I am a passionate hater of public transportation/ mass transit. I want to drive a car or [motor] bike to work. Did the bike in Tokyo... too dangerous to continue.

Raising children in Tokyo... NG.

How well does FRP perform? I see so many Yanki- (Yankee) cars with cracked, broken and taped up bodykits on them... it seems like it is still easily to break than poly-urethane or factory level plastic.

Everyone has pulled into the mall or some parking space a little too much and nudged a pole or another car. I'd hate to do that, or worse... some else do that to my car and have the $1,000 bodykit picece crack or break.

For the above reason and the fact that is looks badass, I've had an eye on the MS kit, but the cost is nuts. I love the styling of the Autoexe kit, but it's FRP and cost isn't THAT much less than the MS kit. The stock front-end and the appearance package is growing on me... didn't hate it, just thought it needed tweaking. But that Knight Sports front with the rest of the appearance kit looks pretty good...

Again I ask though... WTF were the Mazda engineers thinking with that damn half length side skirt?!!!

a good place to look for JDM stuff for your RX-8 is www.intensepower.com

I am excited but I have to ask a few questions. I didn't see the intercooler on the Powers turbo set-up. Does it exist? To repeat how much are these systems going to cost? What are we looking at hp wise with each of the systems? And finally what is the psi with each of the different set-ups? I had a '91 toyota MR2 with a Turbonetics stage II upgrade where we were pushing 24 psi but we had to do some pretty serious engine mods to get there.

I would like to hear that we can push 10-12 psi without steel gaskets and the like. If so are we going to see 150+ hp gains? I am planning on purchasing Canzoomers ECU upgrade and if I put in a turbo I will get a MazdaSpeed exhaust. So with these upgrades I should be able to handle the Air/Fuel mixtures and get the backflow pressure relieved. Should I need anything particular as well such as an ignition upgrade?

mikeb

intesepower.com is very expensive

Japan8

Really? Their bodykits seem to overal be cheaper. I compared the "sale" price to that of RotaryExtreme and Intensepower was cheaper.

NOTE: This was the Autoexe kit, not the MS kit that I compared...

Jt-Imports

Keep comparing things get cheaper hehe

I saw the latest Option Mag (Jan 04) the power increase of the Trust tubro from 215 ps to 265 ps. Wow.. it is the REAL dyno you know.

The Blitz Compressor dyno from 178.9 ps to 215.2 ps NOT bad... different setting of course. I think I like superchanging compressor better. You think?

DangerMouse

I can try and answer your first question. If I'm not mistaken a supercharger uses a belt driven pully system to drive a compressor where as a turbo uses exhaust gasses to spin a compressor . I think the supercharger comes on when you mash the gas which can give you power through out the rev range, and the turbo only comes in when you build up boost pressure when you hit certain rpms.

Well if that is the case then, why would you not just choose the supercharger since you have to wait for the turbo to kick in? A turbo uses exhaust gasses which a car just natural expels where as the supercharger will steal a little bit of power from the engine to drive the belt and pullies.

Now as to which one is better, I'm not going to say either as I'm sure it would start some type of massive debate. I think which ever you choose would be a matter of personal preference. I would suggest you do some research and look at the pros and cons and then make your own informed decision.

Ahh, welcome to the world of oversimplification.

As a user of both supercharging and turbocharging, (my MX-3 had an SC first than I switched to TC, I have a turbo on the Miata and an SC was on the Civic) I can tell you that each has significant plusses and minuses.
None of which are as simple as the above explanation.

The main difference is in packaging and liability - a manufacturer will pick the solution that is most profitable, which means easy to package and least likely to blow up.
Which is better for the owner depends on the ultimate goals for the vehicle - something that the average "I wanna turbo my car" driver has a hard time putting their finger on.

Bottom line from my perspective -

Supercharging is more fun to knock around.
Turbocharging is for winning races.

I'd select a GOOD supercharging system over a bad turbo system for a street-driven car anyday.
However, I'd build a turbo system for my car way before I'd go through the hassle of an SC again.
A conundrum and enigma, no doubt.

TORacing

ok, I'm a little cunfused, so is there a Turbocharger kit out for the RX-8

PetersonPeleRx8

No not a kit out yet but there are many in the works and hopefully will be out soon.

And for dangermouse... you can make a turbo that spools up quickly to give you more torque. It just depends on how you build it. At least that's what I was told by a smart guy on this forum.

More often than not a quick spooling turbo is a small turbo that can't flow well in the high end so you have quick spooling system with good low end torque and power but it becomes a restriction in the high rpm range. Then you have the high end monster turbos that give you the most top-end power but have more lag and less low-end. It all depends on what you're looking for

TORacing

hey there is some guy saying he saw a RX-8 with a turbo and intercooler in the Modified MAG on they RX7 club forum. I thought those weren't out yet, anyway here's the link

Horse---Humm thats someting totally different. It was a conversion done by ACOSTARACING. Thats not a Renesis engine.

93rdcurrent

If you have a large turbo and want to spool faster you can get a nitrous injection system that spools the turbo. This helps with low and med range hp and torque. I considered this system when I was boosting my MR2 to 24psi.

chinx

i'd like to hear more about trust's turbo kit

DangerMouse

Yes, you are correct you can have a turbo spool quickly, but you still have to wait to build up boost. I'm just saying it won't be instantaneous when you mash the gas like a supercharger.
