Thanks JSpeed, myself and a friend of mine started breaking in our GXR28 engines, we set everything to basic settings, we started up our engines and they went to around 300* in just a minute? I tried to richen it up , and it would just stop! I added a head shim even.. Ive ben racing alot of years and never seen anything like this!...someone told me this afternoon that they run hot for around five tanks? any ideas?....Thanks...Fred

This is an awesome class. I would almost trade my MTX4R for one of those if we had that class. Touring cars are too fragile. I think the idea of an onroad car with off road toughness is exactly what the hobby needs.

Cool video.

When I broke in a new GXR28 it acted similar. Ran very hot for a number of tanks. I was trying to just break in by idle (it was my first ever brand new engine and I didn't know there were other options). If I did one again, I'd probably try the Cyrul method on it or something similar.

If I did one again, I'd probably try the Cyrul method on it or something similar where you run it open throttle (or maybe 50% throttle) but extremely rich.

Guys, I have a question, since you can not get GRP tires, what do you think of replacing GRP with the following:

SWK2859 http://www.horizonhobby.com/Products...ProdID=SWK2858
SWK2858 http://www.horizonhobby.com/Products...ProdID=SWK2859

They are Sporkwerks tires...

These are high profile tires, unless you want to run a higher ride height and cut bigger wheel cut outs on the body.

I'm being told that these are good replacements for the not available GRP tires...

I like the idea of all us having the same base set of rules... so I'm asking...

Barry,

These tires are about a millimeter in diameter bigger than the tires on the IGT. I compared them today in my LHS that sells the IGT car. These Sportwerks tires will not be a good substitute because like others have mentioned, it will jack with the set-up of the car.

Keep in mind that 1/8th scale onroad and 1/10th scale onroad classes use foam tires that change in diameter over time. Those guys get used to adjusting the handful of setup differences on a setup board.

If the difference is really only 1mm, the change to your overall drive ratios would also be minimal but you'll run slightly higher geared (more speed, less acceleration).

I wouldn't hesitate to use these if I no longer had access to GRPs.

The Medial Pro tires will be available again soon. I am sending a set out to Jspeed to try out in Tampa. I have already shown they work quite well on a VHT prepared surface (Vegas). They last forever, no need to belt them, and they are not too big in diameter.

I stand corrected on my measurement. There is a 5-7mm difference in diameter between the Kyosho/OFNA tire and the Sportwerks tire. That would mean dramatic changes in suspension to change ride height and you would have to make a major cut in the front wheel wells so the tires could turn freely. My bad on the misinformation from my last post.

Garen's setup was top-notch in Las Vegas in January. Best hooked up IGT I've seen so those Medials are legit.
