Some tasty pics!

 

Before I ask any more questions...

...listed hp/torque numbers are at the crank or at the wheels?

 

Any word on CARB certification?

Edit: Wait a minute, did Kraftwerks finally give up and stop trying? I see no mention of "Certification Pending" on their website anymore

 

Didn't know these were still getting made let alone bought lol

 

Its not a terrabad system, it just had terrabad support when Kraftwerks and Skunk2 started throwing knives at each other and left current customers (like me) holding our dinguses in the wind.

The Rotrex itself is a great little blower, but you have to understand its almost all top end. This is not going to be impressive on the street, but its super fun on the track where you stay in the upper end of the RPM range. Its pretty much the diametric opposite of a PD blower. Running one unintercooled and restricted (as the previous kits were) makes sense from a liability standpoint, but does nothing to really impress anyone who is used to running a T25/T28 on the street or who wants to compare dyno charts. Underspin it and cut its head off with a restrictor and you loose everything the Rotrex does "well".

Horses for courses. I'd run my C30-74 on the track but I'd rather have a T25/T28 on the street.

Brian: not trying to **** in your thread here, sorry if I'm coming off as a jackass
Vlad: I'm not going to get into a super vs turbo debate with you, we all know how that is going to end

 

Oh don't get me wrong man, I'm not putting down the system. I actually considered one way back when they were "all the hype".

I just thought everyone sorta gave up. Didn't know they were still being made and sold.

 

it is an excellent product. I would still use this kit over any other FI solutions out there.

 

Vlad, have you tuned one? I was seriously considering calling you if Andrew was not available. You two guys are probably the only halfway local to me CA based people who seem to know what they are doing with the Miata and Megasquirt stuff.

Brian:

I'm going to ask this now so you can start working on it... but expect requests for a "no blower" kit for the various years.

Are you guys going to start stocking service parts? I need a jug of magical Rotrex juice so I can put the blower back in my car one of these days

What combination of restrictor ID and pulley OD is Kraftwerks shipping for that advertised 185hp number? I assume this is restricted... the pulley isn't bigger than the blower in the picture

 

It is at the wheels. There is a dyno graph on Good-wins site.

 

Can you expand on this?

 

Search and ye shall find. Many long discussions on a few forums.
