I started running the CL7R this season. I ran the JP R9 and 35 Plus last year. The sirio being a 7 port has more bottom than the JP and Nova (9 ports). But it still screams up top. The sirio gets excellent run time and has tons of power. You won't be disappointed. The 2013 seems to be the pipe of choice.

I have just acquired a CL7R-Sti engine second hand. It didn't come with any instructions. Could I impose on someone to list the default needle settings, reccomended nitro% and stock head shimming (it seems to have 3 copper and 2 silver shims installed).

if we r talking about the 0.12 XXX , i have to repeat again it's totally insane!!!
a friend just got it. even still in the breakin in condition i can "feel" the power. and during race its freakin fast esp. the top.

Has the XXX Ver2 been released yet?

not yet bargy, im holding out for it, have you run a xxx yet?

Is there talk about a new XXX?
Haven't read or heard anything about it yet.

Or is it going to be a STI version of the XXX?

Do we know what they are planning to change?
The XXX is not that old yet.

yes a new one is coming , new crank case and they have changed the timing slightly, probably to get a bit better run time
think they are calling it the xxx2
check out red R/C there are pics on there

I dont think there going to use STI I heard something like they got suied for putting STI. Take a look at this

i think it would be very soon, i heard about 3 months ,2 months ago
slightly better than the evo 4sti, i couldnt complain about any sirio i have had they are all good

we have a couple running at our track and they are rockets. very fast engines, same power with a 353
