KINDA MAKES ME MAD THAT I DID WHAT EVERYBODY SAID TO DO ON HERE AND FROM GO TECK AND WITH SO LITTLE FULE ON IT SHE LOST ALL COMP.
ANYBODY CARE TO TRY TO ANSWER THAE QUESTION ON WHY IT DID THAT
OR JUST MAINLY THE ONES THAT TOLD ME TO RUN IT LIKE THAT
Hey grubby, really sorry to hear about your engine, but I don't believe it's anything to do with the info you were given on here. Everyone on here is trying to be helpful, not give out bad info.
To be honest putting a race tune on your motor after only a couple of litres through it is probably not the best practice. It would have still been pretty tight at that stage.
As previously mentioned, if your using good fuel and blowing good smoke with a temp of 300, that doesn't really add up. I would get your temp gun checked out. That's one of the big problems with tuning to temps. Accuracy of heat guns is very dubious (and that's being kind). If you really want to keep an eye on temps, use the good old spit test method. It is as accurate as anything. Ideally the spit you wipe on the head should evapourate away completely in around 4 - 5 secs. If it's sizzling and bubbling the spit straight off the head in a second or so then it's too hot. That's really as much as you want to know about temps.
If your motor was blowing good smoke (at all times) and you still killed the motor, you have other problems (loose head bolts, air leak, but quite possibly tuning issues).

I´m considering trying the GO engines and I have been using a OS V-Spec and I´m satisfied with it but I would like a more mellow/controllable bottom.
It hits like hell on the bottom.
I´ve tried a couple of my friends Novarossi +4 engines with the exact same car/setup as my car including the same clutch-setup and damn it´s a nice engine... Smooooth and fast with good runtime.
Should I try the GX-3R, GX-5R or GX-7R if I would like an engine to perform like the +4?
Thanks for your time.
Hi harleyrules. The closest to the +4 out of those motors would be the GX-7R. It is softer on the bottom than the 5R, but has brilliant top end that you won't really appreciate until you run one
These things are really strong from mid to top.
The 3R is very smooth, but does not have the top end of the 7R
Having said all that, the ultimate GO based buggy motor is the Massive Mods MG66 which is now available in the USA. It is a modded 6 Port motor that is smooth right through the rev range with incredible mid and top end (like the 7R on steroids).
The MG66 would be my first choice, followed by the GX-7R. I run all three motors at different tracks from time to time, so the comparison I have given is pretty accurate IMO. Cheers
