I'm using nova plugs and have very little wetnes on my button it is probably just nova plugs did the performance change from each plug or stay the same

The performance with the #5 Nova plug was probably a little better given the cold conditions yesterday. The engine actually ran a little bit cooler with the nova plug (#5).

But the amount of wetness was quite a bit in that it even leaked out onto the carb and fuel line.

It's my first experience with turbo plugs and I thought they would have sealed better than the standard type plugs.

It could be the tapering of the plug is a little dif then the RB the colder weather the #5 will be beter try the RB plug close to the nova #5 in temp and go from there

Thanks smoke, when I tear down the car tonight after the weekends racing, I'm going to have a look at how well each plug seats with the head off so I can get an idea of what's going on. I'll also throw the calipers at both plugs and see if I can find a measureable difference.

Is this the 5/3port your running did it lose much going to the 3/p

The 5 port was brand new and never run so I don't know if I lost anything or not, I just put the sleve straight in with the original new piston. So I still have a brand new piston and sleeve for a 5 port left over. I did however find that this motor was much more agressive in the bottom end and induced a lot of mid corner oversteer compared to the Picco I was running. I need to work on getting a little more progressiveness (is that a word? he he) in the throttle linkage so it's not so much like a light switch.

Have you got any of your ZEN motors running in Australia?

I don't know if any over there I talk to Geoff every know and then and there motors are going every where. these motors do have a lot ov bottom and mid the 5/p you would be all over with that much power

Well, as soon as I can get a setup that will tame this motor, I'll have to look for something with a bit more top end. I was getting smoked on our long straight by one of the guys running a JP motor in particular. I did however hit the back of him coming out of a turn so my theory of the mid range punch is well demonstrated

A JP is a Moddifed but you new that try the Zen Modded D3R more top end just ran mine for the first time last weekend and only a hand full of guys would beat me down a 250 ft straight buy a few feet so after about a gallon it should be there

I was thinking I might try one of those once this D3 is a bit tired. I think there is some more work I can do with modifying the Factory Team pipe that comes with the NTC3. It's suited more towards the bottom, mid range than the top end. I have a contact over here that has done mods to this pipe in the past so I'll see if I can get the info in order to get a bit more top end with what I've got.

It won't be no D3R/Zen but hopefully it will be better than it is now. Plus the motor is still really tight so it'll give more as time goes on hopefully.

Some plug has too much threads on it. So it can't be screwed to the end. Check the thread of those two plugs you will know what I say.

Didn't even think of that but it makes sence but know i do

Dino proves he's a legend again! It was the number of threads towards the wire end of the plug. I made a small mod to the plug and now it seats right down. I ran two tanks through it yesterday and I was able to tune it easier, it ran cooler and it had no wetness at all around the plug.

Thanks Dino and Smoke for the advice.

Hey guys,

i'm currently running 16% nitro on my D5 atm. Would it rev faster if i put the copper shim back and run 30% nitro?
