Default CRC Nitro Engines

Anybody own one of the CRC Nitro Engines yet?
I'm looking at either the CRC 5 port turbo or the Sirio 6 port .15 OR another Picco XP .12

pops - A few of local racers are running them and like them pretty well for the price. That's the STS RS12 3 Port Modded engine I'm referring to. Francis (jwf_frani) TQ'd and won the Pro Nitro class at Revelation first time out with it. I'm sure the 5 port will be a real screamer.

Default I was wondering

Rod;

Alex Naveretti just bought a brand new MTX-3 and the CRC 5 port. He usually buys the latest greatest and is always very fast. The specs on the Sirio .15 6 port are very impressive too. I was leaning towards the Picco XP12 until these new engines came out. I've been really happy with my Picco .15RE, but it never hurts to have a little extra power.

Default STS Engines

That are available from CRC...I've been running one (the STS 3 port turbo)since they 1st came out, late summer. I've run this engine every weekend (almost) with a std plug and 30% Byron's, (even had it come in once at 425 degrees) it's working on the 4th gallon through it... and it still smoke anything else at our track: MR12's, MT12's, RB's, JPs, Sirios, Trinity Piccos, Rossi Pixi Black, you name it. And best of all....it cost me $125.00.

After the overheat, I ordered a piston and sleeve....it came with a con rod, $40.00.

yeah, but don't believe the hype about them smoking all those other modified engines. Their fast but they aren't that fast.

Default sts engines

I own a sts mt12 engine. I have it in my nrs4 2. This thing runs very reliable and strong. It is also my first rear exaust and/or slide carb engine. I find it very easy to tune. Plus it's legal and for $130, it's a great deal. I have pics of it in my nrs4 album #2. BTW, break in was a breeze. It fired up and idled great.

yeah the price is cheap but the engine feels cheap too.

I've had replacement piston/sleeve sets for RB's that I ended up selling because I never had to put them in.

It's a good, solid buy for the money but it's not a jp by any means.

Default Engine comparisons

Guys;

On all of my Picco's, I have installed Novarossi slide carbs in place of the Picco carbs. This really makes a big difference in power and ease of tune-ability. I believe that the reason for the power increase is the difference in the way the spray bars protrude into the main bore at full throttle.
The Picco on my Reflex is the older .15 Rear Exhaust RR. The newer XP12's are supposed to be more powerful because of revised porting. I have seen one apart and they definitely have changes in the sleeve porting and in the crank.
A couple of guys now have the Sirio 12's but they don't seem any faster than my Picco.

I will have to second that on the nova carbs. I put a nova carb on a 5 port collari and I'm still trying to find a .12 engine modified or otherwise that's any faster.

However, haven't seem to have any troubles out of the STS carb.
