I'm not a big fan of the S7 plug unless you're running really high nitro, low head clearance and hot ambient temps. I'd go with a 6, or maybe even a 5.

Don't take any more advice from whoever made that comment. Any one of those engines (including Sirio) will last equally long if you treat them well. Only an immature fanboy would make a stupid comment like that. Having said that, don't be overly concerned about which engine you buy among those you mentioned. They're all exceptional and the right tune, clutch set-up and driving will make a much bigger difference than the subtle differences in each engine's power curve.

Hi Guys I need some help.
1st question is: what is a good base tuning setting for the Sirio XXX & XXXV being top, bottom & midrange settings?
2nd thing, I have two XXXV's and cannot get them to idle consistantly, could this be due to worn conrods?? both engines have had around 30 tanks through them, around 2.5 litres of fuel (I would have thought the rods would have lasted a bit longer than this from new) What do you suggest???
3rd thing, when I get the engines to what I believe is a pretty good tune, inclusive of a clean bottom end idle, the motor dies at the end of the main straight (50-60m long) from WOT. Basically what happens is that the motor runs OK for 2 minutes or so and then at the end of the main straight when you throttle off for the bend the engine just dies!
Is this a "too lean on the bottom issue"
Just in case you suggest it, I have made sure the idle is not too low.(in fact I make sure it's a little bit high to compensate for this problem)
I've tried richening up the bottom end but then the engine will not idle well. To be honest I'm stumped! I've been racing for over 10 years so I know a little bit about engines but these Sirios are just too hard to tune and keep going!
Yes, they are cheap but that means nothing when you loose confidence in the tune
Help anyone!!!!

Would anybody happen to know if the piston&sleeve form the capricorn cl-9 .21 onroad motor are interchangeable with the sirio cl7r sti. Team epic is no help what so ever. We need a new sirio suppler ASAP!!!!!!!!!!!!!
it is nice when you call about a certain engine when the people that pick up the phone know something about the products they sell and not just how to log-in product #s and act like they are happy to greet your call.

Sirio 21 WCR LC21GT BoxSet OnRd .21 engine/ Novarossi
Hey Fellas, I have a brand new Sirio S21 WCR LC21GT Lamberto Collari .21 box set available if anyone is interested. It is brand new, I just want to move it as I am not going to run On-Road anymore, It is #52 of 500 ever made. Anyone interested? I paid over $700 for it but PM me with your offer please thanks.
I ran another one of these in the past and it was a missile, and a value with all the extras- extra conrod, front and rear bearings, manifold and pipe.
Pm me all offers, no reasonable offer will be refused.

hey guys,
i am thinking buying a sirio xxx vk but i have a couple of questions to make
1. How is the power curve in par with piccos? I am using picco engines and they are great, however i would like a more linear power curve
2. Can i still use picco plugs with the xxx, in case i cant find sirio plugs? And which type is the best?for piccos i have found the 6 cold to be the best for my purpose.
3. How is reliability?
4. Both bearings are ceramic? i know rear bearing is, but i am not sure about the front.
5. With picco and 2607 pipe, i can easily make runtime, whats the case with xxx and 2653 pipe?
thanx

2. Picco turbo Plugs Will Work in the Sirio (Picco plugs and Sirio plugs are quite possibly identical)
3. I Have had no Problems With Reliabilty though it is hard to tune when you first break it in.
4. The Sirio XXXV has both ceramic bearings. But the XXXVk (with the 2653 pipe) only has a rear ceramic bearing.
5. I have used the Picco Evo 3 with a skyline VR12 pipe and the Sirio XXXVk (with the 2653). The Sirio runtime Isnt ass long as the Evo 3 with the skyline but it's still good.

thanks fuin,
What i meant with 1) is that piccos have a very strong bottom, which in some cases is difficult to manage.
I know you can fine-tune this with pinions, centax, or even with exponential tune in the radio, but when i drove
the same car with a nova based engine, i really liked how linearly the power was delivered.
Anyways, piccos are excelent engines for me, but i ll try the sirio and post results.

The Sirio engine is marginal on runtime but it is possible (I have also run the Orion Alpha ABI with the sirio pipes). I make runtime with the Orion engine, but it isn't as efficient as the IDM engines.
