Heads for turbo

[KON]

Any meenings about who makes the best turbo-heads?
I'm riding from 0-4000 feet and think I have to lower my compression a little..
What do You use, and why?

I actually went up in compression on a 2010 dragon motor. I'm running a 12:1 power addiction turbo head (stock is 11:1). The PA head has a much better combustion chamber design that helps keeps det away. Better bottom end power with less detonation. I can run 8lbs at 1000' on pump 91 with the boondocker 3* timing module. Timing module caused me to lose about 300rpm on top end though

I have a low compression head with my silber kit but I have no idea what my ratio is , and have never checked comprssion.

After what I've heard I think I will keep it down on 11:1 in compression because of running on pumpgas and low elevation AND i want to keep it as safe as possible

I read about PowerAddiction and they looks very good, a good cheater head won't steal so much on the low end aswell..
I run the 3 degree timing key but haven't tested the sled yet because I got some DC power issues after mounting the turbo and about 15min runtime =/

not sure what brand it is but I think It said "PAR"....

I can maybe sell my Power Addiction 11.1 head. Going to test a head that Piper has "invented".

I have spoked to piper.. Did he tell you how much compression there was on the heads?
But I have issues to take care of before I can begin with changing the heads..
It's a big chance that I have a stator that don't produce power when I want it to =/

 

[Sunvang]

Never told me no, but he sent me one for free to try it out, and if im happy with it and it really can stand the boost levels he claim. Ill buy it and keep it.

He said so =) I'm wondering if I have a blown stator so now the turbo is coming of again and have to take it to my dealer and get it changed, I'm not happy with that=/ I had an appointment with Piper on Friday to run my sled in the dyno and try with the head they had "invent" and see if I could run 10psi of boost on pump gas without getting DET and see how much power I got..
But, I have to do it next friday instead and I am very excited =) IF the sled runs to then.....

 

[Sunvang]

Well that sucks Good luck on getting it running again, must be pretty ****ty to take the kit of, then mount it again Hope to see good numbers with it in dyno!

 

[KON]

Yes, it's not what I had planned =/
But it's daster for me to make it in stock condition and get my dealer to fix the stator then take out the enginge myself to change the stator, getting the timing right and so on..
And, we don't have so much snow yet so I am very calm.....yet =P
Thank you, I'm hoping for good numbers aswell =)

it will be fun to have your sled at my dyno Kon.. Im w8 for some new parts for my turbo sled, will be running 10-12 psi on 100 avgass for 0-700 meters.

At the same time have a Boss noss 40 hk system to rock when needed
