You spend the extra $30.00 if you gotta have it NOW (and/or are dying for the high-pollish look). :D

For me, I'll wait for the cheaper Trinity version to come out.

The pipe is just as polished as the Sirio. Don't let the picture fool you. And it is not HUGE. Same size as any other. Just a different shape. And it doesn't say Big boy on it. Thanks god. Sweet azz pipe!!

the pic looks a little dull, looks like clear coated unpolished aluminum. Must be bad pic. do they seem durable? or is the aluminum soft? thanks the stinger seems nice and short that good.

got to race my new .24 last night. WOW, on a large indoor high traction track I had plenty of power to clear every jump and very controllable. I was able to TQ and win, after running for 30 minutes straight, and by far having the fastest truck down the straight away, The motor temped at 160. Awesome motor and I am very impressed!

franklucas 01-04-2009 09:19 AM

is there a temp. that should be a minimum? To get proper metal expansion so you dont prematurely wear out the engine. Other racers would have told me that 160 is too low and to add aluminum tape to block some of the fins on the head. to get it around 190+. thanks

for break in you really need to get the motor to 220 at least ...and then back down to ambient temp....this will allow metal parts to expand and contract ....the heat cycle break in method is by far the best ....as far as 160 for a race tuned motor coming off after a main ...i have ran for 3 years and have never had nor seen a motor that would run at a temp of 160 ...case in pint was blipping my grp around yesterday and was temping 160 cuz its starting to break in ...i had to lean that sucker up a few hours just so it would move ....im sure there is some conditions where a motor might run at that temp ...just not sure what and where :confused:

chickenfarmer 01-04-2009 09:33 AM

I dont tune to temp, just by feel and sound. The only time I temp it is at the end of a run for reference.

no offense ...niether do i ...but i have never seen ANY nitro motor that runs good temping at 160 degrees after a main .....but hey the extech .24 may be the only one that does ...one things for sure ...i will find out when mine comes back from powerhouse rc performance .....i would imagine the motor will probably temp at 180-220 range on a good race tune ...after a long main ...i know for a fact that the grp motors dont run well if temp goes any higher than 210 .....i hope mine could win a race temping at 160 ...i will run this motor for 2 years without touching it if it does .....:nod:

chickenfarmer 01-04-2009 10:11 AM

It is only about 30* here right now. That has some to do with the low temp.

franklucas 01-04-2009 10:42 AM

hey zixxer i ran a .21 all last year and it would come off the track after a 20 min main(not fast engough for the 60 min lol) about 190 on average and if i ran it above 210 it started to feel too lean and hard to drive. it definatle has low temps like the old ops engine i used to run.
