If you use 30% maybe. But I use 20% and I removed the shim, installed the turbo head that came with the engine, and installed a NovaRossi ultra cold turbo plug.
I just had a race last night. My temps were around 245 and under after a 5 minute heat. It moves like it should. I'm running with X12's and novarossi 3 ports.
Again, this engine is not the easiest to tune, so have patience and have fun.
For you guys running the Rossi engines, I would suggest you carefully read the following thread about engine shiming.

http://www.rctech.net/forum/showthre...g&pagenumber=1

I think in page 2 or 3 there is an explanation concerning this particular engine, done by Dennis Ritchey (Motorman).

But read all the thread, it's the best 101 on haed shiming i've found.

I just finished making a mod to my g4 in regards to the antenna. It took about a half hour, and it cost 0.00 Basically i cut the stock antenna mount off of the transponder holder and then drilled a hole through the receiver mount and upper deck and then slid my antenna through the hole and just glued on my cut mount in between the 2 screws of the cf receiver holder. This is a great mod to reduce glitching and is quite easy. Any q's pm me
Im so proud of myself J/K!!!

actually there's another way ...just use a 8mm set screw..loctite 1 end of it....screw it into the base of the antenna holder..after it dries just use 1 of the 2 holes that's holding the carbon receiver..just screw it in then you just use 1 of the original screws n washer on the other..... don't have to drill another hole. hope it helps.

Why a set screw? You can just use a regular button head machined screw and screw it in the bottom.

The reason why I'm using a set screw is to tightened the receiver plate. The plate has 2 mounting holes right? I'm using 1 to secured the antenna holder.

Most of the people I have seen perform that mod use just a plain ole screw. It just doesn't seem like a strong substitute using a set screw and glue.

Two screws. The original and the one that goes into the antenna holder.

VoneS: forget about the receiver mount plate, just mount it the way on my car lor, so far no glitch and in the event someone bump onto me, my receiver still can move to minimised the damaged.

Anyway I think all of us did have a good run on out G4 during the race yesterday, everything on the car hold up fine especially the steering system.

Guys if finally got all the parts i needed to fix my car! But guess what as i was changing all the bearings over to dinballs set, i cracked the fricken front one way holder thing. Its ok not bad. Just where you put one of the screws in through the bottom of the one way holder, it kinda cracked where the screw is a little. I swear i can't do anyting right. I wasn't even tightening hard.

I'm telling you guys, the servo saver should be tightened down till where it won't save your servo. I tried moving my servo saver yesterday and it wouldn't move. Thats why you guys are having problems. If you want a servo saver put one on the arm of the servo get rid of the crap TM has integrated into the car. It will eventualy work your rails loose. I have never had a problem with my steering. Its just as tight as it was on day one and i have never adjusted it. The built in servo saver puts extra stress on the rails because it puts different forces on the rails instead of just left and right.

Mike
