So what is better for a buggy 4 or 7 port? I see alot of guys going with 7 port motors. I thought 7 port engines hsd more bottom end and better in truggy. I know pipe and clutch have alot to do with the way sn engine performs.

Btw, if anyone is on the fence about an Elite 5, nows the time Nova direct has them down to $119

Link?

Thanks. Hmmm....

I run the Mito 4 port on smaller tracks and the Mito 7 port on larger tracks like LCRC. When i run the 7 port in Buggy, i use 41031 manifold, 6.5mm restrictor, 9901SS, and 25% nitro. When i use the 4 port just change manifold to 41021. Truggy i run 41031 manifold, 7.5mm restrictor, 9901 non super strong, and 30% nitro. I use the new C5TGN plug. love that plug.

I've been wanting to try one of those out. Does it tune pretty similar to a c5tgc?

What's the speculation as to why these engines are being sold off at these prices? Not that I'm complaining about good prices - engines have been overpriced for a long time. Just curious though...

I think it's a pretty simple though. Supply/Demand/competition. Supply has undoubted been steady and heavy. Demand, personally, seems to be less - I see more and more "other" branded motors at the track. Competition has exploded - once Nova was only through Odonnel, and he charged whatever he wanted.

Novarossi direct and absolute look like they're buying from italy direct, and Odonnel looks like he's allied with Amain.

So the former dropped their prices to make them the go-to places for novarossi.

This is ALL made up speculation, if you want facts, ask Chad Phillips or call Novarossi in Italy.

I am running a race this weekend that is doing 8 minute qualifiers, I am trying to figure out the best course of action to make 8 minutes. The best I have been able to do is around 7, maybe 7:15.
Here is my setup:
MBX-7R
Keep-Off 21-4
9901ss with 41021
I had the 6mm restrictor in the carb, I have now swapped to the 5.4 but haven't run/tuned it yet. The motor has about a gallon and a half through it since new.

Doing a search in this thread, there are some old posts with guys getting 10-15 minute run times, I am nowhere near that.

If I do stick with the 5.4 restrictor, what should my tuning strategy be to start? Just lean the crap out of it?

Thanks in advance.

no totally different. its a new plug. The c5tgn is easy to tune and idles beautifully.

When we started buying from Novarossi and saw the margins that previous importers were charging customers, we felt it would not be fair to charge consumers those prices as they were way to high. We chose a price that would allow everyone purchase at a competitive price without breaking the bank. Which is why everyone else had to follow us

going smaller on the insert doesnt always mean more runtime. Drake runs a 7.5mm restrictor in his MBX7R. Everything makes a difference with runtime... Fuel, glow plug, pipe, header, and most importantly... vehicle. You take the same motor and install it in a losi vs Mugen. Guarantee the Losi has way more runtime.

Thanks Chad, I will put the 6.0 back in and work with that and see what I can get out of it. It seems that many are having about a 2 gallon break in period and then the engine comes alive? I guess I am almost there. I don't have the fuel economy gene in me. Leadfinger can be a problem sometimes. :O

What fuel are you using? Put a 6.5 in. Look at it this way. In theory.. If the engine is fast with tons of power, you will pull the trigger less and gain more run time. choking the engine and having your finger buried in the back of the trigger can hurt run time.
