Lookin good, gotta love getting things on sale.

 

[dub c]

Nice! Real nice! I am so jealous right now....

 

[Ckeithnitro]

Supposed to be a good engine... Nice hopup for my TMAXX
Gonna run the 3.3 I modded some more first...I like it alot!

 

[jerzey10]

That's a great deal.

I was wondering why the OS 21 is 250 and the picco 26 is only 200. is the os that much better? I know its not as strong as the picco.

 

[Ckeithnitro]

not sure why its more $ only got it because it was around $200 with the header..
love my picco's the O.S is just something to try out..
can't wait to fire up my Picco .21 p9r evo3

OS has been in the hobby a long time and just verry reputible,they build a great engine

My guess why it cost more is the OS has a better set of bearings and comes with a header. IMO OS engines set the standard for all the others. You will be very happy with that engine for a long time.

the 21tm would have to be the simplest engine to tune,nice upgrade over the 3.3,i', still waiting to see if the picco is better but

They are all labeled by there displacement. Some are measured in cubic centimeters and others are measured in cubic inches.

haha blame the phone for that post
what i was trying to say is that the 21tm is a great little engine and i still havent been able to compare it to my picco yet

 

[scootr]

Had a chance to compare yet?

 

[chickenman242]

picco deff has more power but the one i have is being very tempermental
i took the os out for a run yesterday and i gotta say i'm very happy with the way it performs

 

[moe7404]

i put a 21tm in my jato, its great. do it, do it, do it

 

[scootr]

Has the OS 21 tm got much more than the 3.3?

 

[layne5t]

I've got the 21tm in my 2.5 maxx and she keeps up with my buddies jato 3.3..... until 2nd gear I'm running a stock clutch bell and a 64t spur ans it still wheelies on command
