true. i totally agree you can only get so much outa a tiny engine. i just think they could do a lil better. or just cut the price. like how they were have a special in april. keep that the regular price.
ANY IDEAS ON WHEN THE 10PSI IS COMING OUT?

 

yea and for the price of the fit + turbo/supercharger you could have a car that in stock form would walk the Fit.

 

also, a turbo is less reliable and requires tune after tune after tune... the kwsc is basically plug and play

 

One tune is plenty for the turbo kit. And properly tuned, it's just as reliable as a supercharger. I'm tired of these unbased comparisons.

 

The variable ratio traction drive planetary transmission drive system on the KWSC is superior in design to that of conventional blowers and exhaust turbine driven blowers.

 

no more SC fit ?

 

I has a s/c

 

I put one on my car in May and loving it.... Trouble free, linear power feels more added displacement than a bolt on power booster.... Honda should build cars with the Kraft Werks S/C offered as a performance option.... The Rotrex unit with traction drive is amazing.

 

still going strong @10psi.

 

I am so very glad that it is still working well for you..... I will be going to 10psi as soon as my finances will allow..... Right now I have to do the louvers on the hood and see if there is a drop in temperature that will result in something I can feel on my tired old butt dyno....Thanks for dropping by.https://www.fitfreak.net/forums/imag...lies/wavey.gif

 

I updated my list for spits and giggles.

 

i think the turbos out numbers the SC on this forum

 

I feel sure you are right.... Turbocharger kits were already available when the Fit was first imported to the U.S. or very shortly after..... I now have upgraded to the KWSC high boost kit with Hondata reflash, intercooler, and RC flow matched injectors..... I am very happy with it. Owners of some of those cars that are held in high regard for their acceleration and speed didn't look at all happy as I glanced at them get small in the rear view mirror.... The only extra maintenance required so far (16 months) has been a belt adjustment that took less than a minute to do.... This thing is ridiculously unbelievable.... I can't help but giggle like a little girl when somebody revs their engine at a stop light or pulls beside me, down shifts and there is open road with no traffic ahead.

 

i've been reading throught this thread and i feel like such an idiot for asking what i'm going to ask, but really, ive never looked into turbo, or supercharging before.
if someone wouldn't mind telling me, what is the differenence?
from what i've read, turbo seems the way to go for more power, but it seems to be harder on the motor, and needs a constant eye. if i'm wrong, please correct me, this is just what i'm getting. checking out a couple of vids on youtube, from the one that was posted here, a supercharger sounds really nice. i love the sound of a BOV with turbo, but i know nothing about how to even go about it. lol.
i'd consider putting a turbo, or even a supercharger on my fit(09 GE8) but i haven't the slightest clue what is even available for my car. i'm sure the pricing of all this is something rediculous and might end up being a money pit.

 

Turbo uses exhaust gases to spin the turbine.
Supercharger uses the engine via a belt to turn its turbine.

That I'm aware of, there's neither available for our car (GE), as a kit I mean.

 

u can buy some china turbo kit for GE on this forum...i believe someone posted pictures of it.....check the GE part of this forum....

 

harder on the engine, not so much. easier to blow the motor with a bad tune? yes. but get a good tune from the beginning and you have nothign to worry about.

the maintnance thing is a myth.
since i put my turbo on, the only maintnance i have done to my car is.......oil changes. lol

 

The only guys I have heard of that have blown up there engines with a turbo were putting way more boost to it than it could handle.... Down here a turbocharged engine runs too hot in the summer, over heats at sustained highway speeds and the A/F ratio has to be set very rich and timing cut back to curb detonation.. Doing that causes oil dilution and in turn shorter duration of driving between oil changes. I was aware of the traction drive planetary transmission that allows the Rotrex supercharger employed by Jackson Racing in the KWSC kits and how it would be able to boost at low RPM with out with the boost pressure neither rising or dropping as it gained revs.... The Hondata reflash raises the rev limiter to activate at 7200 RPM and the speed limiter is disabled making the car capable of attaining speeds that are pretty amazing and torque that has turned my motor mounts to mush. I read of the tuning philosophy that Hondata goes by and they tune to make power without placing undue stress on the engine... Eventually I hope to add a methanol/water injection system to my setup and see if I can safely change the A/F ratio to run a little leaner with it by employing an AEM F/IC do do the changes mainly for improving fuel mileage at partial throttle operation and to drop the combustion chamber temperature at full throttle as well.... The very linear power delivery is the biggest difference I feel between the Rotrex and cars with turbos.... The intake temperature reading is higher than I'd like. I could change the location of the sensor as I have been told is done with some turbo kits to get a lower reading but since Hondata programmed the ECU with the sensor where it presently is I am pretty sure it wouldn't make any difference.

 

I updated my list again and added a new pic.

 

I am sure that's totally true for many many people, but I just want to throw some more experiences out there. This is relating to a Miata, and not a Fit, but I think it's still kind of relevant to show that turbo can be smooth sailing, or it can have it's issues.

I have a friend with a 1.8L Miata who put a Flyin' Miata II turbo kit on with ALL the goodies and everything needed to make it run. He couldn't get it tuned well but in the end decided to take it to Flyin' Miata themselves, and they gave it a fantastic tune. He ended up making 260whp @12psi, and it ran fantastically well. A real hoot to drive too as you'd hope. But since then it's gradually started having issues with the tune, and he's really had nothing but trouble. And this is a kit from the most reputable Miata turbo guys, tuned by one of the guys from the same shop that builds the turbos!

I know it's a different application, and a higher power one than a lot of Fits are running, but I think it's good to be aware that turbos are not *always* smooth sailing once they're well tuned. My friend has been pouring money into his car for the last two years to get it running well again, and right now it's running poorly and failing emissions tests.

For sure it can go really well, but be aware it's not guaranteed
