g martinez do you know the timing of this engine?
anyone else?
thanks!

MHarrison,

Thanks for the info. I ran a Nova 2630 on the motor this last weekend and it was better on the bottom than with the Sirio 2611 but I think I lost a bit of top end speed. It works well at our local track though because it's so short and has a tight infield. I am going to test with the Skyline plus 12 next time out.

Regards,

Based off the Sirio Evo 4 & tuned to capricorn specs

I was thinking about replacing the conrod on my CL12E after break in. The only place I can find it is at the Capricorn site. I'm really trying to avoid ordering online from overseas vendors but if push comes to shove I just might have to.
I'm sorta sure it works but is it 100% the Evo 4 STI conrod is a perfect fit in the CL12E? Damn, so much for the cool laser etching eh?

Cheif you can order Capricorn parts thru the U.S. Distributor
www.murnanmodified.com
as for the Evo4 conrods it should a direct fit but I would double check for you

ithink tht this pipe is the best way for your problem

I just didn't see any listings for a conrod on the Murnan site. But still, thanks for any and all help.

It is there now.

Check under engine parts.

is this pipe legal to use in a national or world event ? big tom

Ran the 12ET MM motor for the first time over the weekend. It behaved flawlessly, made good power (but was hard to compare to my other engines as it was a very small and low traction track). I ran it with the 2611 pipe, but have a 2604 pipe that I plan to test at a larger track.

It has about 2.3 litres of Tornado 16% fuel, it was still locking up on the starter box before the mains, I still cannot turn it over without a plug, so this is very impressive!

I pulled it apart last night, the internals are all still shiney and look brand new, it didn't see past 118deg C. The piston/linear is bedding in very nicely. This motor has alot of potential, I still think it is about another 1-2 litres away from its full potential. I will order a spare rod for it, as I think this tight pinch could be adding some extra strain on it.

I agree with most of the above comments, yes it is a Sirio based motor, but I think the quality is much better. I ran the new Sirio XXX about 1 month earlier and it did not have anywhere near the amount of pinch the Capricorn has.

But so far, two thumbs up

Tom is has a new efra #2648
since there was a change to the original 2611 under efra rules & was not sudmitted to efra on the changes that's why it was ruled illegal & then had to be resubmitted with the changes in order to receive the new efra #

Just did and just ordered! Thanks!

anytime

The guys that found the 2630 to be the better pipe, what manifolds did you find to have the sweet spot, 5/6/7 fin?
