You can by Australian made ones Al, probably about 30 bucks...
The 390xp is low on compression stock, about 150psi on the average. Reducing the squish/quench to .020-.025, plus a .020-.030 popup really wakes them up.![]()
Must be a Aussie thing, every site I found was in AustraliaI guess wearing shorts and work boots isn't as popular over here, thats to bad.

I'm gonna petition to have your Hillbilly permit revoked.:hmm3grin2orange:
Lop the last 8" off of the sleeves of an old windbreaker with elastic in the wrists.

Stay safe!

I've said this one before.
Cut the last 6" off the bottom of your old tracky dacks with elastic bottoms, turn em upside down...instant gaiters!
So in the end what compression did that 660 end up with the popup, and was there any pics taken of the popup ?.
Cheers all
I totaly agree with you Matt about dropping the rakers,but what i was trying to do was keep everything that i can control the same to get a fair comparison between them.
Unless Im way off on my math then you have a gain of 2.27% from stock vs. modded on your 660. The times i got were as follows
Stock 9.60 & 8.13
Snelleriized 9.34 & 7.78
Thats not much in the way of gains at all. Am I missing something here? Shouldnt a modded saw get atleast about 15% more?
