Performance Polaris Cfi Cylinder Heads for Turbo and Non-Turbo applications

1200psi · Jan 11, 2010

Here are Power Addiction's heads for all CFi engines . I have them for 700 and 800 motors.

Power Addiction CFi performance cylinder heads have a much better design than the stock head, even the new 2010 Polaris Updated head ad are much less prone detonation with noticeable performance gains.

Power Addiction heads have been put on Dyno-Techs dyno.

The 13.6 domes made over 10 hp difference over the horrible stock-design head .

I also make heads for you turbo guys in lower compression ratios. Here is the list of different ratios I have. Custom orders are possible for an extra charge.

Power Addiction heads are made to accept the Stock Polaris Head cover.

I have anodized billet head covers available for 100.00 additional (shown in photo)

800 cfi engines
12.5 13.5 14.5 for Naturally aspired engines.
11.0 and 12.0 for turbos

700 cfi engines
13.5 and 14.5 Naturaly aspired engines
12.2 for turbos

$330.00 with shipping in the USA

PM me with any questions you might have Brad Wursten, Owner Power Addiction Racing

how much $$$$ what is stock compression on a 700cfi

deepdiver · Jan 11, 2010

Checked out your web site..Very nice looking work Brad!

1200psi · Jan 11, 2010

my website sucks I need someone who know how to build me a good one.

The 700 cfi are the same price.

well brad your machine work is beautiful..might have to get a set of these when I have some spare $$$....

send me a set n i will tell everybody how good they work???

lets say you stay at stock compression since these are a better design you could possible run a lower octane fuel "if" you were willing to risk it

Brad,

This is great work as always.

Can you post up the Dyno chart on these heads?

What engine was the 10 hp noted on?
Did this 10 hp come with a different pipe and fuel map?

What kind of gas is required for 13.5 CR? (same for 700 and 800?)
What kind of gas is required for 14.5 CR? (same for 700 and 800?)

Do you have the anodized covers available for the 700's as well?

Do you offer your head for the 600 CFi motors?

M'horse,
The dyno runs were made on my 800 CFI motor. And I tried 3 different sets of domes. Unfortunately, my motor is not stock, and I never ran the stock head (I somehow must have misled/confused Brad, as he is a very straight up guy), but Dyno Tech has ran heads which were modified to have similar squish and chamber shape as Brad's. This design has proven to provide the best power with the least amount of detonation on these motors.

The key with these heads is their ability to keep detonation at bay, while still allowing good compression and squish numbers. Not once during the testing (20 or so pulls) was even one click of detonation present (I was running 93 octane oxygenated pump gas). Considering detonation is what prevents most of the 800 cfi's from achieving optimal afr's and thus power, these should be a must have for anyone who is looking for improvements in power for their 800 cfi's.

And yes, the heads are a work of art.

is this intended as an improvement over the updated motors or the original (08, 09) design? or both? look nice either way.

Thanks Neil for the chime . These heads are for all the motors and would be a substantail gain over any of the stock heads.

I have been running one of Brad's turbo heads on my 700 CFI since last January 09 and absulutely love it. Detonation is not an issue anymore and I have run some big boost numbers both on purpose and by accident. I would definately recommend using Brad's products. He is also a great guy to work with. The quality is top notch.

IQRIDR · Jan 13, 2010

I have customers running these heads who are very happy, we run at sea level with very high air density. I also run a lot of Brad's other products...you won't find better built stuff.

700bigblock · Jan 13, 2010

i live in minnesota and ride at sea level. can i safely run the 13.5 head on pump gas with a 09 polaris dragon 800?

1200psi · Jan 13, 2010

I would do the 12.5 would be a better alternative for sea level .

Brad

mtnclimber19 · Jan 13, 2010

does anyone know what the stock compression ratio is on the cfi 700 and 800? Just for comparison

1200psi · Jan 18, 2010

I have them at work I will see if i can remember to look and post them.

Clarke673 · Jan 19, 2010

i am looking forward to geting a set brad! Everything else i have got from you works flawlessly!

Vfrtrader · Jan 19, 2010

the 08 poo head was 13.6, current update head is 11.6. Would we have engine trouble with your 13.5 head like the dragon have had? Or would the 2 ring piston fix it?

tree climber · Jan 19, 2010

how much more boost can you run on pump gas with the low comp head

The reason they are blowing up is some of the head you can not run a 13.5 at sea level without some kind of high octane fuel at our elevation 6000 and above no problem for the 13.5 that is what i sell everyone from 6-10 k and the 12.5 0-6 k .

On the turbos also alot of that depends on boost and how your sled is set up and elevation. I make the 11.0 more for sea level guys and the 12.0 for the mountian guys I would say if you want to run straight pump fuel buy the 11.0 and be safe .
