congrats Rex

did try the 8mm venturi today and retuned the engin.It did really help alot.

Did suddenly get the punch in the start that i need for the jumps.
Glad i bought two arrows.
And the novarossi BTT is now only a reserve.
If there wil be a new novarossi in my car later ,it is only becouse someone gave it away.
I did already since i started racing use 3 novarossi.They al lasted 8-10 gallons without changeing anything.

So if the arrow last more than 6 gallons it is good bargain..

1st engine touching 8 gallons. compression is still great. there's 2 head shim still in it. Bearings are in superb condition. No conrod change.

Happy to hear that. :-D

That's great, Rex! Your customers will really like these motors. Interested to see what kind of extra oomph you can do w/ your magic as well!

i know i am not suposed to drive the car on the head .....but now another cooling fin fall off.
pitty....it is to bad becouse the rest of the engine is wery good..:flaming:

lol cooling heads aren't for landing on XD

we have a tripple jump here that i always take as one.
So the force when i land on the head is wery hard...
Anyway,that is only a problem with arrow,no other had that happening with other kind of brands.Not even me.

that is Odd Even Strange :mad:
When i think about it odd even strange is a name her in norway.

did try the 2060(efra 2042)pipe today....
I am not so shore about the diference between this and my RB 2087.

But today i didnt do so much stupid overdriving.I think the 2060 have less in the top(not screeming so much) and seems smoother al the way with no lost of power...
This pipe defently fit my driving skils better.
It makes me more confident.

I have both 2060 (EFRA 2042) and 2087. The 2087 works great on the new long strong engines, but never thought about trying it on the older short stroke. :tire:

What header are you using on the 2087? The stock RB 198mm "7" shape header it came with?

Try the 2087 with the 2060 (round M2000SC) header. It will add some bottom and smooth out the mid range. I would guess it also picks up mileage too.
