I just don't want to run ally. I don't like the corrosive properties. Gas is more reliable. If I have to I'll run Sunnoco GTX 104 before I run alky. The reason I want to run a dome piston is to get to 11:1 without milling. Because I know nothing about valve train clearances and geometry...
Has anyone ever used one of these high compression pistons from bullfrog motorsports in a Hemi predator? According to their website with no other mods it gets you to 11:1 compression. I was thinking it'd be a lot wiser to do this than mill my head to get 11:1. Ole4 reccomended this to me but I...
Ole, this is the head I am referring to. Head, Racing, GX160/GX200, 18cc : Genuine Honda core. And I have changed the idea of going with the black mamba jr to the black Mamba so i can get the longer duration to be able to pull start it with the 13.5:1 compression I was looking to achieve with...
Hmm.. would it be better for me to go with the stock valve size and aluminum retainers then for $100 less? 27mm intake and 24mm exhaust. Also will I have clearance or geometry issues if I use a 18cc head milled .050? I don't want to have to use cut to length pushrods
Actually I was doing some research and I found out that the 18cc head milled .050 will result in more horsepower due to its better flow design. You can order one from NRRACING FOR $310 and it comes with a .050 milled head, 28mm SS Intake valve, 25mm SS exhaust valve, titanium retainers, dual...
So if I am going to run the 14cc gx160 head how do I know what kind of valves, springs and retainers to order for it? Is everything the same as the Hemi besides the diameter of the valves themselves?
Awesome thanks for the info Ole4!! Very helpful. Does anyone know what the highest compression I can run on 104 octane Sunoco race fuel is? Can I run 13.5:1?
I am sorry OND I think explained that wrong. I have not taken the head off of my motor yet to see where the piston is, but wherever it is I plan on making it as close as flush to deck as possible with a longer ARC rod.
I'm sorry I'm confused. Why is it that you want .030 distance between the head and piston? If my piston is flush with the deck wouldn't I still need a .045 gasket to get the .030 clearance between the piston and head?
I have thought about that. And I would like to use a .02 longer rod and a factory .045 gasket. Would I have clearance issues with this setup? And with a compression ratio of 14:1 can I just use race gas? Will I be able to pull start 14:1?
Interesting, I am also curious whwat is the highest compression engine you can pull start? I'm a pretty strong guy but at what point does it get rediculous?
Here is the pricing list you asked for,
Billet Flywheel $100
ARC Connecting Rod $84 +.02
Black Mamba Jr. Cam $70
26lb Valve Springs...
First off I have been reading for a couple months but I am a new member and this is my first post. I appreciate the tons of info I have already found but I still have some questions. I am building my first Hemi 212 Predator. I will include a build list of what I plan on doing and then ask the...
