KRAFTWERKS SUPERCHARGER aka (Jackson Racing)
well, the amount of torque the tranny is anticipated to handle is one of the major design factors in materials selection and ultimately weight. honda uses high rpm to achieve hp from a low torque motor, allowing for a lighter transmission and ultimately lighter overall weight car.
with that in mind, i do think that automatic guys should be very interested in the testing results as far as durability over the long run. the plus side is that the fit is a light weight car. the question is what is torque and factor of safety the engineers chose when selecting the final design of the auto in the fit. handling nearly 50% more torque, i'm guessing, was not in the original design parameters. again, i'm speculating, so i'm really curious as to what KW's durability testing has determined.

Please back up your quotes before posting. Yes it does have a limiter of 115 MPH.
ERR what speed limiter? I think if you read the following threads you will see the FIt DOES NOT have a speed limiter.

can this thing be installed by itself, as in no other mods.. stock exhaust etc?
I read the siphon article and it says it's fairly quiet and gives the impression of a larger engine at all rpm's. They compared it to a stock fit on the same run for mpg purposes and it only lost about 1.5mpg compared to stock (something like 29mpg vs 27mpg 91 octane, running some mountain road or whatever)

How old are you? I don't think you're mature enough to be on this forum. You can bust all the 115 MPH all day but the factory ECU monitors the true limited MPH. When it hits that speed, fuel is cut and limited to 115. We can talk all day about this, but this forum is not about how we can break the limited speed barrier. I'm just stating the facts. Enough said.
I've never seen a speed limiter referenced in a wiring diagram or ECU pinout. Pretty sure that's all internal to the ECU software....just like the rev limiter.

And I say PROVE it show us your SOURCES for your UNPROVEN THEORY THAT THE ECU MONITORS VEHICLE SPEED. You can't just make up unsupported theories like that without indicating where you got this information and "because I think it's true won't cut it." and my brothers neighbors, mother-in-laws, sisters, aunt anecdotal STORIES are not sources of competent information. If your unproven theory is true then it would act like it was hitting the RPM limiter with engine cutting in and out and it DOESN'T do that. Your trying to convince us that your an expert on the JAZZ/FIT specific ECU but yet you have owned one for a TOTAL of 2 weeks geeze I sure would like to become an expert in 2 weeks and what work have you done on your FIT besides the rugs?? So be sure and let us know how you came about becoming an expert on the FIT ECU in two weeks so we can all do the same.

I'm old enough to be your grandfather. And no where did I say I was on a ROAD youngster NEVER ASSUME ANYTHING you make an A$$ out of you and me ...remember that one???.

anywho, i agree with gg06mr about it being an internally controlled parameter in the ecu, not actually something you can physically see. you don't have to be an expert about anything. I'm sure the speedo will say 120, but even that isn't tha big of a jump from 115, and certainly not worth arguing over.
besides, unless i had some suspension work done, i'd be a little weary of going that quickly in the fit.
chris, so does the charger do away with the speed limiter? i would assume not...

If the OEM ECU is reflashed as part of the fuel correction for the added airflow then I would suspect that they'd remove the speed limiter while they were performing the reprogramming.....assuming one existed.
It's very common for factory speedometer readings to be very optimistic, especially at higher speeds, so it wouldn't surprise me if a Fit displaying 120 mph on the speedo were actually traveling closer to 110 mph.

thanks gg. i was aware of factory speedomters to be optimistic, but you worded it much more nicely.
This thread is not worthy of a 'sticky' just yet, especially now with all the bickering.
Anyway, once the SC comes out everything should be summarized in a new thread with pics, links, dynos, install FAQ, etc.... then the thread should be closed and only able to be modified by JDMChris or other person knowledgeable on the product. The point of stickies is to find quick useful information on a topic.... which is almost impossible with this 25 page thread.
Sorry abt your thread OP

whoa whoa whoa. this thread has PLENTY of info its just mostly towards the beggining. actually, there is a decent amoung of it spread everywhere. and since the kit has NOT come out yet, there is no need for another thread 'just yet' and i'm pretty sure the neccessary people are aware of what they have to do when it does come.
in the meantime, this is the best place to discuss the charger and all aspects/things related to it. bickering happens.
Nice numbers on the dyno, 144whp & 123ft/lb
, I didn’t expect that much for 5psi, and it’s also a beautiful torque curve. I’m curious what the 10psi kit would make, 180whp if my math is correct!
Which leads me to a few questions, I know you will have an upgrade for the 5lb à 10lb kit, do you know how much it may cost? Also what would a 10lb kit cost, and how much would the intercooler upgrade for the 5lb cost. Lastly if you do buy the intercooler for the 5lb kit, will that reduce the price of the 10lb upgrade? I know that these may be hard to answer at this time, but if you could ball park some numbers that would be great. Can’t wait to be installing a SC on my fit this spring!!

You Pro speed limiter guys are all JUST GUESSING and SPECULATING. No one has offered ONE IOTA of evidence to back your GUESSES. Not one line of code from the ECU programming, not one indication in the wiring diagrams, not one mention in vehicle specifications, Not one line of instructions from ANY Aftermarket ECU on how to raise or lower this illusive speed limiter. You guys have nothing but pure speculation.
And now your trying to pass off "speedometer discrepancies" as the cause give me a break your guessing again because no where was it mentioned how fast this supposed limit was surpassed by. It could have been 130 or over but you don't know that because your just guessing again.
Your all surmising that the FIT has one because your old Yugo, Hyundai, or Schwinn had one but we are not talking about OTHER CARS nobody cares what you did with or had in your beloved civic this post is talking about whether or not the FIT/JAZZ has a speed limiter and so far you guys have nothing but speculation no EVIDENCE WHAT SO EVER.
