[QUOTE=GrandMasterKhan,Jun 12 2009, 10:49 PM] If you've got stand alone tuning you could buy a C-38 series blower and retro-fit it for use with the KW kit. There's been a lot of talk about that. Ultralight has done it successfully on his race car. I

 

that would be the ideal way to make everything work.

In my expeirance the rotrex intercooler stays pretty damn cool during runs. I wouldnt be surprised if it could handle another 100-150 hp from a c38.

Unfortunatly it doesnt seem KW is willing to make a C38 kit even as a race kit like they offer for the RSX. Its a damn shame really. Because i'd love a 500hp rotrex power monster w/o the heat issues etc like one would get with a turbo.

 

The C38 has been discussed before. It does not work for our cars. The efficiency range is not correct so you end up making the same, even less power than the C30. Move on.

here we go again

 

Yeah... I suppose we do have to go thru this again, since IIRC the mods locked up at least three KW threads, that may or may have not addressed these questions.

For what it's worth, I searched for 'Rotrex, C38' and came back with only a handful of threads. One did have an interesting quote from OJR at Kraftwerks:

"For those that want beyond our kit (450+hp), the C38-61 is the best choice... There has never been an argument there. All I have been saying is our kit is not designed for those folk.

I think the KW Kit *is* great, but with modding cars, I'd like to know what (if any) expandability this kit has. I was specifically curious about UltraLite and his 'KW C38 conversion' - If indeed I understood the quoted poster correctly. If this *has* already been discussed, be all means, send me a link and I'll refrain from 'stiring the pot' again.

 

The long and short of it is, if you are happy with ~365whp, buy the KW kit. If you need more, look elsewhere or prepared to re-engineer the vast majority of the kit yourself.

 

That's really great info.

Thanks.
