At sea level, yes do put a .1 shim in with 30% fuel.

Yes, it's a high end novarossi motor built to Mugen specs (what differences it has between the Mugen X12 and Novarossi NS12, I dunno.)

BTW...very good motor (even with standard plug). I can keep up with some very good modded engines on the back straight of my home track (200+ ft straight)

Thanks for the info Dark Angel. I'll make sure to shim up correctly.

The motor is definitely really strong. I was finally able to start mine up on Saturday, and this thing rev's high. When the 2speed kicks in on my prospec, it hits HARD.

I can't say about adding a shim at sea level. Here in Vegas, the air is usually a little thinner, and the only engine I ever added a shim to was my Rody V12. It is a high end stock engine from Novarossi.

No need to add a shim as long as you use the right plug with 30%.

Which plug would you recommend using with 30%?

Right now, I'm using McCoy MC-59 plugs with 20% trinity fuel.

I run O'Donnell plugs, so if you are going to use one of them, use the 99 with 30%. If you drop down to 20% use the 77. In the winter, you MAY get away with the 77 at 30%. If you try the 77 with 30%, I would inspect the plug every 2 tanks and look for the wire distorting. If you change the head button to a turbo button, use the O'Donnell 99t plug for up to 20% and use the 97t for OVER 20%.

On the pipe, the only pipe I can recommend (sp?) that is in the under $50 range is the OFNA X12. I would bet there is a good RD Logics pipe at that price point, but I haven't tried it or seen it run.

All of the pipes I run are the nova based pipes and I really like the Mugen pipe and the RB X12 pipe, but they are about $100.

Thanks Scott.

Right now I have the RD Logics pipe, but it looks small compared to other racer's pipe, on the same car. I was thinking of getting a skyline pipe as well, but the Ofna X12 pipe looks to be a great deal. Some places are selling it for less than 40. I may have to pick one up.

I'll try out the plugs you recommended. My LHS stocks up McCoy and OS plugs, so I'll have to find a shop that sells the O'donnel plugs.

Have you heard good things about that OFNA X12 pipe?

I had the plug numbers backward regarding standard plugs. I edited the post, but I wanted to let you know ASAP. Sorry..

I have an X12, but I admit I have not personally tried it. I can say two very good racers here that I pit with both have run it, so I have raced against it and feel very confident in recommending it. Like I said, I do have one based upon how it ran for friends that I trust.

No problem bro. I have a bunch of MC59 plugs that I'll be using. They seem to be working great.

I went ahead and purchased the VR12 skyline pipe. I've read great things about those pipes.

I would trust Scott Fisher about specs at Vegas (wish I could afford to go to the Paris race this year) and most other places. We don't shim our motors up in Colorado Springs due to the lack of air, but when the guys go down to the Paris race they do as a precaution (couple of our guys have popped plugs in Vegas because of not shimming). You could try it with stock shims and go from there. Changing plugs can do the same thing, it's just advancing or retarding the timing of the engine.

I'm using the VR12 pipe right now with the Mugen X12. You'll be happy with it. Better than the RD logics Turbo II.

I was supposed to get my skyline pipe yesterday, but hopefully it'll come in today.

Now, I have two MTX3's...one will be a backup. I just need to buy some nice servo's, which will be soon since I just sold my HPI Nitro Mini.
