Plus with a turbo setup u have to setup and pay for dyno time and tune.... The KWSC is plug and play.

 

We will be making kits for 5 and 10 PSI. You are associating boost with horsepower, which is incorrect... Especially with the Fit. The cylinder head is VERY small, with very small ports. It is hard to port out the ports anymore; they are as big as they can get.

We will be posting information about our Time Attack Fit very soon!

I dont know how to install a turbo or supercharge..so.. i have to paid too in supercharge... its the same.

about the tune.. i assume that i can speak with T1R for the proper tune configuration. all the fits its the same,no?

and.. the turbo kit T1R can be installed in AT or Manual. the Supercharge have to be specify for each transmission. :S too bad.

 

Well from what you seem to know i wouldn't suggest to boost your motor (esp. turbo) untill you know more. No two motors run the same...each will have a different tune with turbo to obtain a specific level of power. Where you live, how you drive, how the motor runs...all affect the tune. T1R can give you a base map but you would have to tune on your own from there or find your own tuner (Unless you live by T1R).

With the kraftwerks kit its plug and play...just install and ENJOI . Another thing I saw is your power level is 220 whp, now I'm not saying that the 10psi will hit that mark for sure but I don't see it to far off because the 5 psi kit with full exhaust is ranging from 145-155. Thats even without the injector upgrade. Either way you will need exhaust so that doesn't matter. Anyway just giving you something to think about...

What is the latest we can preorder the kit and still receive the 10% discount?

 

Once we establish a firm ship date, that will be the cut-off for pre-orders, and the discount.

Okay, I still don't quite get it. A more free-flowing exhaust would reduce back-pressure on the exhaust stroke, right? How would that affect filling the engine with supercharged air? Somehow there's less time for the intake stroke at a given RPM or something? And if the injectors with the base supercharger kit are at their limit with the stock exhaust, how likely is it that a more free-flowing exhaust isn't going to cause the engine to blow up?

Done.

 

Keep in mind boost pressure is what the engine cannot take in. More freely flowing exhaust will allow the engine to breathe better, hence, more hp. Starting the intake event with remaining pressure already in cylinder due to exhaust back pressure robs power.

 

The free-flowing header and/or test-pipe will help scavenge exhaust out of the cylinders, allowing for more supercharged air to enter the cylinder. But you must be able to fuel the additional air. That is where the upgraded injectors come in.

The upgraded injectors are required when using a header and/or test-pipe. The gains when using header, test-pipe, and injectors are substantial! I will post them soon.

wait, so will it be safe to run headers/test pipe/ and exhaust without upgraded injectors? From what I know, Chris is running those without the injectors and is reaching 145whp...but is that not healthy for the motor then?

second question, what's the required maintenance on the rotrex supercharger? What kind of oil does it use and how often does it need to be changed or checked?

 

this is from the official FAQ:

"Do I have to maintain the Rotrex supercharger?

The Rotrex supercharger is a sealed unit that requires no internal maintenance. Because the Rotrex supercharger has its own oiling system, you should check the Rotrex oil reservoir periodically to ensure proper oil levels. The Rotrex oil should be changed every 2 years/50,000 miles, whichever comes first. Feel free to change the Rotrex oil more often, depending on track/race use. Also, be sure to inspect the supercharger drive belt, as you should any drive belt, at every engine oil change.


What type of oil does the Rotrex supercharger use?

The Rotrex uses a unique traction fluid called Rotrex SX100. SX100 works by momentarily increasing viscosity under high surface pressure, enhancing the traction drive performance by securing the optimum friction between rolling elements while cooling and protecting the system. The Rotrex pumps its own oil and does not use engine oil, so there is no need to tap your oil pan. The Rotrex SX100 traction oil is available direct from KraftWerks."

 

Any additional information in regards to the AT model, and also CARB approval date would greatly be appreciated.

AT was stated to be available at the same time, but it's been 2 weeks after so far, so an approximate availability date would be great.

Currently this kit is CARB pending, and I have seen CARB pending on the 96-97 240sx turbo kit for over 5 years, and it has yet to be approved for Greddy the last time I checked so a date of approval would be nice, not saying you won't have it, just wanting to know since I live right next to the Police station.

 

Hey Oscar,
We are having a track day with the Yarisworld forum, and the are bringing a few F/I Yarii out there as well as a few of us fitfreakers with your kit. I do believe the individual with the power enterprise kit will be there, as well as a couple with blitz superchargers and one with turbo if I am not mistaken. Was just wondering if you would be interested in showing up with your Fit as well?
Thanks,
Tom

 

he said it MIGHT be available at the same time. it wasnt for sure.

 

Will Kraftwerks be offering the required, FOR ME THAT IS , upgraded injectors or will I have to get them from somewhere else?

 

yeah they are coming out with them (according to Oscar).

 

yes the injectors will be available from Kraftwerks.

 

uh...you would have to specify with ANYONE what transmission you have, as the kits are not the same.


if we go by your logic, then yeah, the kraftwerks is the same for both the auto and manual, because its the same supercharger.

 

Answer:
Chris has been using the upgraded injector package the entire time. The mileage he has reported is with the injector upgrade.

The upgraded injector package will be available when kits ship.

thank you thank you thank you.


my above post? yeah, completely disgregard it!
