Im sorry to the OP. I dont want to be the asshole with the attitude. But KW and members on here have been playing with our heads about a c38 option for the old kit for years. Now to come out with an entire new kit (which is what the majority wants) and have smaller companies advertise for them makes me scratch my head.

All we want is the raw facts. What rpm the blower is spining at on the provided charts, most importantly what rpm the blower CAN safely spin to, and what size pullies will be made available to purchase. There are more questions, but until we know those three questions I will not bother with any others.

I have reliable sources who have spoken to KW employees quoting 450hp shouldnt be a problem on these kits. But 450whp and 450 engine hp are two very different things.

I feel the community wants a rotrex kit that can support 450whp MINIMUM. I hope KW will post dyno plots and spec sheets for a s2000 with these figures before they expect people to upgrade to this new kit.

ahh, I'm just too trusting.

 

Ive been reading more on the TTS set ups with these blowers. they claim 20 psi with the c38-91 and 17 psi with the c38-81. they have a few making 500 hp on pump gas. but I dont know any feedback on those cars at all.


KW just needs to show us these blowers can make the same psi with their kits and I know the power will be there. Then this will be something big to talk about.

 

OP didnt know what they just stepped into

 

The original kit was c30-94 -- the new one is C38 ???
Question, is the C38 unit can fit to the old kit C30 bracket? --- I am only asking the Bracket.
Do you have to buy the new c38 bracket???

 

As far as I know the C38 unit will not fit where the old C30 kit was located that is why they changed the kit.

 

i find it odd that the stock ap1 with the kit makes almost hp as the ap2 with mods. Although the ap2 has more torque which probably because of the .2 liter difference. I'm interest in this kit as well, just hoping it be realible. 400 whp would be nice on a ap2!!

 

Yes it will fit. I have documented proof. The problem was NOT fitment...it was lack of ability to drive the C38 compressor with the 6-rib belt...there was not enough traction and it would start to slip badly around 6krpm. It was moved in order to properly drive the unit.

 

Haha!

 

TTS does a bottom mount replacing the A/C compressor, but looks like they drive it with an 8 rib belt (and includes replacement pulleys). Seems like that could still be an option if fitment is not an issue.

Do you have pictures of the bracket used to mount the c38? (and/or a source for that bracket)
