I have noticed that on some your s2k with KW kit the intake is slanted to the left.
Is this in order to bring the intercooler charge pipe up from the bottom of the car..cause I know it tends to hang a little low..

I think I'm nearing ~4k miles on my -91 kit.

 

~5k on my KW -91 kit.

 

Less than 200 that including the trip to Evans tuning from nyc

 

Since a lot of threads have come up with the belt breaking issue, would anyone on here be nice enough to make a video of how to properly install and tension the SC belt on this kit? You'd not only be helping me, but much of the community that have purchased this kit.

I didn't install the kit myself and I have had one belt break already. At the price tag of $144 to have the shop install a new one, I really don't feel like having to shell out that money again and again if the belts are to continuously break. My plan would be to carry a belt with me and then the basic tools to be able to change it on the fly should I be out and about and the belt snaps.

Sure it would be nice to ask Kraftwerks for an installation video, however, I doubt their response time would be that fast in making one opposed to a forum member that could possibly do it in their garage.

Thanks!

 

Not the best picture but maybe some others can get the same pic so we can get an idea where everyone is at tension-wise.

C38-81 90mm blower pulley 128mm crank pulley. Make sure to post your pulley specs as that should change tension bolt length. I've been at this tension for 1k-1500 miles, many trackdays, 0 issues.

 

Question regarding the cogged belt setup on this kit:

It seems like a lot of people reporting that the stock rev limiter causes damage to the rotrex unit due to the cogged setup. I am wondering how big this issue is and how people can minimize the chances of damaging the rotrex unit.

is there a way of adjusting the rev limiter so it causes less damage to the rotrex? For instance use a ignition cut instead of an fuel cut? Soft rev limiter?

I do see alot of videos on youtube where people seem to hit the rev limiter (shooting flames at high rev shift) often, im curious when actual damage occur to the rotrex. Is it damaged when you hit the limiter for a quick moment? Or do you have to beat it violently and hold it into the limiter for a few secs?

I can imaging that hitting the rev limiter is something that WILL happen eventually when you go through 1-2-3th gear with 400+ whp at your right foot. The revs will climb really quick compared to oem, resulting in a bigger chance of hitting the limiter.

Who can give a good answer to this one? Ive checked alot of threads and cannot find a good answer/solution to this issue. Except for chosing the TTS kit instad which uses a regular belt which allows slip when hitting the limiter, thus protecting the rotrex.

 

I don't know if it's proven that rev limit is what's breaking Pulley bolts ... Habit forming says he hit rev limit hundreds of times .. I never hit rev limit since I broke my pulley .. And I feel that it's an issue .. So I'm doin what i can to not redline .. I would go Tts just for their pulley system in my opinion .. The tuner will set soft limit for you .. Evans did mine automatically cause he was aware of the issue ..

 

I'm at 15k +on my kit installed a year ago about .. My recent upgrades for track include a spal extreme fan and oil temp and water temp dual spa gauge .. First track day will be most likely end of April with Nasa ne at Watkins glen . Will hopefully still be cool out ..

 

There seems to be a lot of "internet-lore" about Rotrex blowers and rev limiters. However, there doesn't seem to be anything from Rotrex or any other credible source about avoiding hitting the rev limiter.

The stock limiter on my '06 had a recovery of 300 RPM lower than the limit. That meant that when the car hit the limit, the RPM would come down 300 RPM before the ECU allowed it to accelerate again. This is what causes the stock car to "bounce off the limiter". With the Flashpro, I have the recovery set at 0 RPM. This prevents the "bouncing".

I wonder if a shift near red line where I go from full throttle clutch engaged to clutch disengaged and idle as fast as I can move my feet changes engine speed faster than hitting the rev limit with the clutch engaged.
