Agreed, Rex does a great job!!

Well, I sent it off to Rex, we will see what kind of majic he can produce.

do you still need carb boot i think i found extra one here for it thnx will g

what are the advantages of the 3r over the 3s?

The 3r uses a larger higher quality rear bearing, has a bigger cooling head and comes with a turbo button, Also the timing is not the same.

The 3s is a amazing engine for the money its powerband is very short and it spools up very fast, it can be a benefit on very tight tracks.

All in all the 3r will have a long smooth powerband and the 3s will have a short powerband that spools up fast, both engines get good mileage.

thanks looks like ill be getting the 3r then. our track is a decent size but is quite technical so

the 3r is ballistic, i must have a good one cause mine has had no issues in 2 gallons and screams, very very happy with mine so far. here's my next motor tho...

Is that GO 5PT engine made for Caster to Casters specifications?:sneaky:

It sure looks like a Go!

Rex

It's a Go 5pt alright just like OCM had. I really like the look of the cooling head very nice. it'll be interesting to see how it's priced compared to the Go engine.

22Racer, u got PM,,,, thanks

I have the .21 seven port turbo and it had been the best motor I have ever owned. Sent it in to russell here to make sure everything was alright with it over the winter. Will have a brand new one come next spring.

engine mods, what's common
 

This question is directed to anyone who wants to throw an answer back my way. I'm not new to mod'ing engines or R/C. Just new to R/C with wheels. Anyway... what are common mods to R/C car/truck engines?

Changing bubble volume
changing bubble shape
changing deck height
tapering squish bands
changing Compresion Ratios
changing port timing
"turbo'ing" cranks
and so on...............

Having a boat background Im used to moding the crap out of engines to have peak torque and HP at un-godly RPMs.

Right now my intrest in trucks is ripping down the street, not racing

chunk

so i just got a brand new trinity .12 touring edition draked. 1.62bhp and 44000rpm. its not bad...... but i need help finding a clutch nut for it. Does anyone know what i nut would fit? thankks

the carb on my 3r has devoleped the "wiggle" i remember reading here about. couldnt find a post about a fix. it seems to be leaking fuel around the base of the carb and running lean. any suggestions??
