Yes, in order to get the car operating best with the 24mm pulley do a 2mm split between the front tires. Usually when I open a box of fresh foams I measure fronts and back tires and then true the fronts only. I also find the 25T pulley to be easier and provides more acceleration especially for technical or smaller tracks. Also less truing required means more lap time for me on the track.

Guys,
What brand of foam tires do you guys use at the moment I am using Jaco Nitro Shoes are these ok they came with the car.

I found the stock tires with the car to be quite exceptional in both hot and cold temperatures however those are the MSR tires I believe. I also use the Jaco tires, but they aren't the older style 5 spoke rims - they are the new ones. The rims are far more sturdier than the ATS and have great wear. I can run some hard laps without them wearing down as fast compared to other brands.

Hey everyone, I am new to this forum. I just picked up a mbx4 roller and was wondering what set up is best. What engine, tires, settings, pipes. etc. Has anyone heard about the new mtx4x upgrade? anyways, thanks for the shouts.

There is no best setup, but then again there is a best STOCK setup and that is the MTX4. I'm not far off from the stock setup. Just build the car, test drive it and make adjustments to suit your likes from there.

I found a slightly used ninja for it for 275. but have heard some remarks about that engine and issues w exhaust... what engine is running strong w this car?

rmdc1: come out to speedworld and we will set you up....a good start is the setup yllib posted here. As for engine, the most consistently fast I have seen is the Nova 12-3sct, that engine has won 99% of the races at speedworld in a mtx4

There is nothing wrong with the engine or the exhaust. The issue was using the FLS or, fast link system, was that if the exhaust was hit in a hard crash the manifold would snap off the engines' exhaust port. Other than that it is an awesome motor. I am quite fond of the Novarossi though.

JayL- How much more consistent is the SCT vs the JLR? Is it really worth the $$? Truthfully though people who have sworn by other less expensive engines have still stepped up to a more expensive mill.

JayL

HarKonnenD: love the Dune name btw , the guys running jlr, at my track, always have issues early in the day, the tune is waaay different every race day and they waste practice time tuning. The guys running the sct throw it down maybe go one hour on top and boom, practice time is on....

Really the money will be made up buying sleeves etc, as the Nova internals last longer, in my experience

JayL - Thanks for the reply. I have been pleased with the reliability though with Novarossi and RB in the past, but it always seemed for less $$ they make engines that are as fast and reliable. Though most of them were all top end with a mildly smooth. The Novas had great power band all around. I wonder how much they go for nowadays. If anything purchasing one will do the trick and I can leave my two OS motors for warm up. One day going to the GLC will become a reality, though doubt the OS motors will be worth using for practice on a track of that size.

my local hobby store has the 12-3sct, that's ceramic rear bearing for $389...seen them online for $350ish. great deal for a great engine IMO
By buddies has over 5 gallons of 30% in it now and it still rips for the win.

I went back to 20% and found it to be just as fast as the 30% in my TZ though using the Swauger clutch setup. How will it do in the SCT? They shimmed for 20 , 25 or 30%? I just want the standard version though not the one with Ceramic bearings or anything fancy. If anything maybe I will get it with them.

JayL

funny you say that about nitro %...MY bud and me just switched from 30 to 20 and have the same rip with alittle larger tuning window and more run time. For 20 or 25 you are fine, for 30 you should add one of nova's thin shims. I would stick with 20 as you said.

Just make sure to get either a plus 12-3ST or plus 12-3SCT, you want the 's' crank, the c is ceramic rear bearing, I have only seen them both for the same price so I would go ceramic for the same price...
