Status: offline 		some people have been complaining about the 8.0 engine, saying that it's hard to tune and runs poorly. is this true? or did they have dud engines? should i think about a 4.60se insteadof the 8.0?

Good race day, finished all the heats in 2nd, but flamed out twice in the A main and i gave up on the third time, narrowed it down to a fried plug, 4 race meets does that to a plug i guess Still managed third though

Status: offline 		I think the 8.0 is very easy to tune and get running very well if you especially start with those revised AE settings posted here on the forum. The truck holds it's tune as well. I think since it's a larger engine it's not as finicky and has a smaller rpm range to work in. It can take a few mins. of running it around to fully warm it up however...but even cold it still drives good.

These are the ones that were sent to me...

"First thing is pull the carb all the way out (full throttle position). Then turn the Meter Mixture Screw (back of the engine next to the idle screw) 1 and 1/8 turn out from complete close. Then keeping the carb in full throttle position turn the low speed needle 5.5 turns out from complete close. Then turn the high speed needle 3 turns out from complete close"

I would say my truck was nearly dead on with these running 30% Byrons or Sidewinder Race blend and a MC9 Plug. Motor takes a couple of mins. long to reach it's operating temp, but this only affects full power...Otherwise it's snappy right after you start it. I might be 1/8th of a turn leaner on the Low speed and 1/4 turn leaner on the high speed from these base settings and the truck rips and actually runs cooler...But that maybe due to the 30% fuel as well and the colder plug.

I also don't think you need to do what Tuc says in holding your carb open while making these adjustments as I found no difference...But if somebodie's carb is completely off then maybe. Verify your idle is set to spec before doing these adjustments and then your idle should be good after doing them. Let me know how your's runs after doing this.

Status: offline 		Is there anyone that knows of a company or companies that make hop ups yet for the MGT 8.0, besides the A arms from RPM? pipes? headers? shock towers? anything?

All hopups made for the older MGT's except engine and tranny stuff will fit the new MGT 8. Page 2 and 3 of my site shows all the hopups you can put on the MGT 8.
