ok guys i have been trying to find sometihng like this for a long time and i found it tonight ..... http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT

ok the price is not that friendly but i want to know if anyone has one or what you guys think....

 

I think 4500 is pretty expensive for 40HP.

Why not just install a 100 shot of nitrous and supporting mods for MUCH less and come out with more power still.

 

The supercharger is forever, cost is finished after install. Nitrous is cheaper to install, but an ongoing expense forever, plus maintaining it. Beyond that nitrous may be good for the random stoplight race, perhaps the dragstrip, but are you going to use it day-in day-out, on the way to work, on the track, on vacation.... were do you get your fix and at what cost.

I'll take the supercharger which gives good not amazing results in a wider range of RPMs and loads. Moderation in all things wins out in the end IMO.

Good find shawn81 . The cost does not seem unreasonable for a quality kit, and who says the boost can't be made a bit higher? Are you writing them for more details? Wonder who has info that perhaps has seen these out in Japan?

 

Or on the other hand...

Nitrous can be turned off, supercharger cannot. With a flip of the switch you can merely cruise without having the nitrous come on whereas supercharger you can't. When it is on, you can have it up to spray automatically at x rpm, therefore cruising rpm's don't have it spraying, but once you want to have some fun you can have it spray automatically at say 5000rpm or 4500rpm or lower, whatever you want. The days of fast and the furious pushing a button to spray are over, it is very easy to set it up to spray automatically at a certain rpm. And to set up a switch for off/on.

Sure you have to refill, but I'd be willing to bet the refill/install costs put out over time will not equal the cost of the supercharger for a long time. **** think of it this way, the difference between nitrous parts/install and supercharger parts/install put into an investment that yields a fixed percentage. Then every time you need to refill take money out from that account or investment, it'll take even longer to become the same price!

 

any idea what it uses for engine management? For $4500 you could get a Greddy turbo kit plus Interceptor, or pay a little more and get a PTP kit. Both will give you better results. Not worth it in my opinion.

 

Not too bad of a price for "buy it now" because it comes with a new intake manifold.

Karma has it listed for 4300 Pounds - Who has a Wall Street Journal to look up the conversion rate? It's about 1.7 to 1.8 isn't it? 4300 x 1.8 = $7740 USD

 

A supercharger is only working when you need it. The rest of the time it is just spinning. Just like a turbo. The Blitz kit uses a clutch anyways. Nitrous is only working when you want it to, not when you need it to. Nitrous is worthless in corners and it's worthless on the street for daily driving. When you take off from a light, it'd be nice to have a couple of pounds of boost to get you going. Sure you can set up nitrous to come on at part throttle but what a waste. The supercharger won't stop working when you need it the most. A supercharger will make it feel like you always have a larger engine. Nitrous will make it feel like you have a larger engine for a few seconds at a time and only at high throttle. Nitrous has no use on the street other than street racing. OK nitrous has no use on the street. Only on a drag strip but why would you drag race an RX-8? A supercharger isn't a thousand psi bomb waiting to explode. Leave a bottle heater on all night and see what happens. It's the pressure, not the gas that is dangerous. I do agree that $4500 is alot for so little though.

 

You are very narrow minded towards nitrous. It is very easy to set it up to come on at whatever rpm you want, part throttle or full throttle, and make it worthwhile for more than high rpm's.

My only point was that it was a lot of money for only 40hp... jeez one comment and people take a **** on this forum.

 

Well i have to say 4500 is again alot of money but you know i really wnat to know what this supercharger can do i mean with the turbo i know guys that are running it at 5 to 9 psi now don't anyone have an idea of what this one can handle ..... or better yet forget about the $$ which one is better for my engine? turbo or supercharger? i like the turbo for the $ but i don''t want to change an engine every 40k. I know the turbo puts alot of stress on the engine b/c it will boost at a higher rpm... now how bad is bad.

 

thankx man but iyou are right we need some one in japan with more info. pic. HP readings. dyno

 

This is the 1st supercharger kit I have seen actually for sale.... I have heard talk and talk from others that are working on it...and working and working .......but I am pleased that Blitz actually has a product for sale, hopefully this will make the other companies to hurry up...........

 

the blitz kit has been around for a while...

 

Would be nice if Pettit would just release their SC without EMS and let us get to it ourselves with like the Interceptor should we choose to go that path...I say the same about RP's Axial also, though I'm guessing both parties are too worried about reputation and improper tuning/blown engines to go that path...

And 4500 is way too much for the power offered.

 

It's because there are plenty of us who have been down the N2O road, and found it wanting. $4500 for 40-50hp FOREVER is MUCH cheaper than $700 + $40/bottle for 40-50hp for 90 seconds at a time.

 

if you look at the specs it says that it is for the RX-8 and suits engine 13B. Probably a typo but should be checked out if anyone had interest in it

 

That's cool - I hadn't noticed the intake, nor do i think I've seen ANY kit turbo or supercharger w/a new intake. Perhaps I wasn't looking, but that shows some in-depth work on Blitz's part.... plus less tubing.

 

i know SC is easier to instal am i right > ?

than turbo that is .. ?

 

No...well, could be...but the install of either isn't the hard part - the hard part is tuning. Everything else is just nuts and bolts.

 

superchargers can have a bypass set so they dont produce any boost

 

the engine in the rx-8 is a 13b

 

w/ an SC, is boost also controlled by load? I remember on my previous turbo car, I could drive around all day and NEVER get into positive pressure.

 

yes

 

yes they are controlled by load, thats why you cant produce boost by free reving.

 

Thus there is NO validity to 'You can turn off N2o, but you can't turn off a Supercharger'.



On/off is controlled easily by driving habbits.

 

40 HP at "Standard boost" , does it say what that # is? I mean if it puts out 40hp @ 5 lbs thats great but if its @ 12lbs. , thats not so good. Also would like to know about the ECU.
