Default Sirio CL7BSTI

Sirio CL7BSTI w/ 2013 pipe or 2057 pipe/extender!

Have a look at one of the recent magazines that did an article on the CL7BSTI engine. They claim it to be the most powerful .21 out of the box they have tested! I know I run mine stock and all I can say is
DIALED!!

Default .28 vs .21

28's are overkill for Truggy. If you want to bash / aren't worried about being the best you can be - get a .28.
If you want to have the best opportunity to be the best you can and want consistency for racing get a .21!

To each his own

My main word in there was Consistency.

not all 28's are inconsistent. i barely ever have to touch mine from week to week, stays right around 235-240 and in a 6 minute heat i come off with just under 1/2 a tank left. same plug it was broke in with and a gallon later. pretty consistent to me. but again opinions are like something else everyone has

i have the 8t race roller with the o.s. v-spec and the o.s. 2050 pipe and 30% nitro. lot's of power and run time. it takes 5 mins. for half tank. if your track is bigger then get the o.s. 2060 pipe. more top end.

As a newbie, how hard is the V-spec to tune and will it hold it's tune very well? I've heard the race spec engines are more finnecky.

I am currently running an 8t with OS Speed and 2050 pipe which is outstanding if you want to spend the extra $$. Regular V-spec and 2050 pipe is a great combo. Plenty of power and the fuel economy is great. I was running the Jammin .21 for awhile, but the front bearing went out after about 1.5 gallons. Seemed to have plenty of power to push a 8t. I will eventually change the front bearing in it and keep it for a backup motor.

Default Consistency

What I meant by Consistency isn't the motor itself. It's the driver. One of the recent magazines just did an article. Scott Hughes ran a .21 and a .28. He had a slightly better lap time with the .28 but was way more consistent from lap to lap with the .21! Consistency is what wins long races! Hence why most pro's you see are most likely sporting a .21 in the Truggy! ;-)

easy to tune and hold the tune very well. just don't touch the mid speed needle.

Thanks for the info.

I am trying to decide between the Jammin' .21 and the V-spec. Both are supposed to be good mills.

I think Ryan may know what he's talkin about since he is one of the best pilots in the COUNTRY/WORLD and races/competes against the BEST in the WORLD... So he just might know about what is consistent and what may be best if you are trying to go fast... Just my .02.... Sorry but the local guy running a .28 may be fast locally but try going fast on a USA/WORLD scale... Totally different and I am slow on all scales.....:l

I definitely recommend a .21 in a truggy. Any race bred .21 will perform in a truggy...
