Why change teh head if its running ok.
My one runs at 108/111 deg/c and is happiest there but i still need more bottom punch.
Will be changing to Nova carb and see what happens.
It runs great with teh VR12+ pipe.

so i have experimented and the novarossi heads fit. I put on a mugen x12 head and i still have all the power from before but it runs cooler with an extra fin or 2. cheers

I think he just want to experiment with different heat sink.
The hole line up with Nova. I have tried all the NS based and all the Max and they all fit and I will try the OS magnesium when it comes out.
Razzor, I believe you run 16%, I would try get it to run up to 120 ( meas when the tank almost empty). I run 25% here and in Summary(temp 33c plus) , I run it up to 120 to 125. In winter ( temp 15 to 20) I run up to 100.

I am using a new version of the HEC pipe with a smaller manifold, good power and run time cause of the increased Torque.

Holy shiz, this motors a beast! How much is the stock axial from stores?

YO bro, i thought i had the latest version whereby the manifold is super big that i have ever seens. looks like i need to get 1more end of the month when i go over. kekeke...

yoo..

what you have is the larger manifold and (more) conical. Its more suitable for large or flow type track. The pipe is the same, just the different in manfold. Get the 5mm set with new manifold since they interchangeable so you have spare...

Is this HEC pipe better than the Skyline?

From Kitracers description i believe he prefers it to teh VR12+

but VR12+ is not available in HK rite Kitracer??

I am not sure if pipe is the same ( i havent seem a VR12 +) but I am sure the manifolds are different.

Dont think is available in HK.

We have the first AXIAL CUP in HK today. Great Turn out and lots of Lucky Draw prizes. Will post picture later this week.

K, I took 4th place at Pattaya, Thailand On Road Party Race. Will post pics soon!

Nice
