CNC ported, +1 valves, kibblewhite valve springs. This is one bad head! Pricing coming very soon!
CNC PORTED NYTRO HEAD
- Thread starter XtremeSpeedShop
- Start date
Cost of Cylinder head assembled ready to go is $1700.00us
Includes:
CNC porting
CNC valve job
Head surfaced
Kibblewhite +1 valves
Kibblewhite valve springs
We will be doing a lot of testing here soon with our Nytro motor in a drag quad chassis, so we will have dyno results soon. I will also have the flow bench graphs here soon. Also have some cams that Paul at Impulse has worked on. From our experience with our raptor Turbo and some other Turbo projects is not so much huge Hp gains but quicker spool up and a lot harder pull through the RPMS.

so do you offer a core deposit?yes porting & cams make a huge diff in throttle response its almost like a n/a sled crazy fast spool up,i have both done on my sled. 
The 1700 is the price to have your existing head built. We are working on getting a few heads set up to do an exchange program to speed up time needed to get you on the snow.
If I can get a few guys committed to the Apex I can get a head going for that also.
About what would it cost.
I will have to figure that out, of course more with the extra cylinder. Here is a before and after pic...
Sorry had my Nytro and raptor head mixed up, the nytro uses Kibblewhite valves!

Whats the bowl area?Looks good
Looks like you guys did a fair amount of work in the bowl area. With most engines thats an area where there is some power to be had.
Keep us posted on the dyno results!

Whats the bowl area?
Its the area above the valve seat and can also be refered to as the "pocket".
Cleaning up this area usually improves the angle of the flow to the valve face. Also re-working the area just up stream or above the valve seat improves air flow when the valve is just starting to open.

Thanks! Im excited to see the Dyno results myself!

This head would work awesome on a N/A motor especially combined with some good cams and some compression. Would like to see one go myself
I have a full ported head on my nytro from Hurricane and the throttle response it stupid fast. My timimng is set at 114. For those of you looking for hp and response gain head work is the answer. I would be interested to see your flow numbers once you test the head. Are you planning on smoothing out all the areas, in and ext?
