what temps r u seeing out of the motor

I have a rb mods GX-7R I get around 10.30 to 11.0 on this track. I drive smooth on the throttle i am not one who keeps popping the gas in the turns, temps I try to keep under 260 but mainly look for smoke at the end of the straightaway.

In my truggy with a v-spec J series carb on a 7pt go I have pitted at 12 min in a 25 min race ( good thing I didnt dump it late in the run) 245deg. temps

Here is a pic of track talked about above LCRC at lost creek Pa.

nice track

If you want a gx-r 3 port combo let me know.

As donut racing seem to have stopped trading can anyone tell me where I can get a cnc machined cooling head for my MG66..kingheadz and trinity/epic have several but don't actually list GO as a fitment..Are the heads that fit OS or RB able to fit..I don't have any to try..

heres one on ebay 390173712445 item#
GO Tech .21 7P Cooling Head Nova RC Products

O.S. heads work on Go Engines. I just noticed that Amain quit carrying these engines, whats the deal?

Has anyone tried the 2013 pipe on the GX5r

Yes

and does it work good?

it is possible to install kit 7 ports (21-2207) in a crankcase 3 ports sport (R2100-M00HSG)?


sorry my english!!!
