Hi.

The TUNED version has:

Hand modified Crankshaft
More aggressive P&L timing
double ceramic bearing
Black threated crankcase

Thanks - now I really want one.

Is your engine mount best for mounting this engine in the NT1?

Of course yes!!!
iw work perfectly.

thank's

Blee any updates on your CL12
My motor is going strong with a lot of pinch after the nationals & 1-2 day state race & 1 club race I would say a little over 2 gallons on it

Bro., I still do not have a chance to touch the engine (very busy recently).........

i will be trying one of these engine's this weekend.

I tested the engine eventually…….. same performance as my Sirio EVO4. I will modify the engine to enhance the performance later.

looks to me like 7 transfer ports and 2 bypass ports

Mark Harrison finished 2nd A Main Sedan using the Capricorn lt wt Shaft & drive train pulleys in his RRR

I think I'm gonna give one of these engines a shot. For those of you that have the Capricorn .12 motor and ran em', what is your input and what is a good pipe or pipes to run with them. Thanks in advance.

Sirio 2611 I can't remeber which nova pipe# uriah was using

The Sirio 2611 will work fine with the enigne. I have used the Novarossi 2601, and RB 2604 both with medium headers. That also works very well.

The engines run great. They make lots of power, run cool, and make great fuel mileage. A tough combination to beat.

They're basicly Sirio evo4 engines right?. But then rebranded and tuned a bit?.
I'm asking this because i want to know if ít's proven technology and not a totaly new concept which could give problems.

Hi Uriah,

did you run yours stock or did you put your magic wand to it?

The tuned engines are more like the new XXX Sirio, but with some hand tuning. The timing is different than the old Sirio Evo 4. The fit, and finish of the Capricorn engines are better than that of Sirio. This engine runs better, and has more power than the Evo 4 too.
