Yes, it is McLeod RXT Twin disc setup
I think it feels great, but have not tested it for proper load yet.
Heads are SRT8 but with larger stainless steel valves and easily ported intake and exhaust.
CPR fuel rail with gauge.

Thanks, I just pulled my drivetrain and am thinking about going with that twin disc clutch, and doing some head work with a new cam. I read that that clutch is supposed to be very easy to use, not jerky and super tough

Vilket snyggt bygge!
There is no point in having an x-pipe when running turbos?
if it was mine I would paint the IC black..  :thumbsup:

Tackar.....Thanks!!
X-pipes are for naturally aspirated Engines I Think!
Has never occurred to me that IC can be painted.
Perhaps I would do it ... not a bad idea  :cheers:

Spring 2016
I could not stand the noise of the fuelpump (Aeromotive Eliminator)
Switch to the Dual Phantom pump in-Tank with new tank and sender (Tanks Ink)

Dyno ended in broken engine.
Run No. 21 the first pull up to 6000rpm....something happened.
Ticking sound that later proved 4 pushrods broken.

Dyno testing for boost and backpressure.
Visit my friend on his rolling road.
Examines unstable boost pressure.

Awsome for the update.
Sorry to hear/see the failure issue.
Fully expect some of the same issues in my TT treck. Some day...

Best wishes you have the bugs handled and can go at and enjoy it longer.
