Ieat4strokes Posted January 11, 2009 Report Share Posted January 11, 2009 as title says...... if u had a few extra bejamns laying around what would u do? noss head with 21cc domes? or v force 3's? which would net me the most gains now? ima do both eventually but as of now wifey only gave me a small budget...... mods are just fmf phattys with power core 2's and gearing.......timing advance +4 Quote Link to comment Share on other sites More sharing options...
MDS2106 Posted January 11, 2009 Report Share Posted January 11, 2009 (edited) Just save a little more money and get a decent port job.It will do more than the reeds and head combined.But if I had to choose between the two I would pick the reeds.I was never a big fan of cool heads...

It will add HP. I dont think the reeds add Hp, mostly throttle responce. I would also go with 19 cc domes. I put them in all the pump gas motors I build. At my elevation 19's put me at 150-155 psi.

Dirty Sanchez Posted January 11, 2009 Report Share Posted January 11, 2009 I would go with the head too. Double check your elevation before you chose dome size. I went with 20's at 1900ft. Im pushing the pump gas threshold at 158psi Quote Link to comment Share on other sites More sharing options...
fastrthnu Posted January 11, 2009 Report Share Posted January 11, 2009 the cool thing about the noss head is it looks good for 1, 2 runs slightly cooler helping prevent detonation, and you can trade domes for racing or std riding, plus if you ever get a stroker crank, you can trade cut domes. As for reeds vf3`s are nice, but for $45 on ebay you can pick up decent set of carbon fiber reeds that work almost just as well. so it depends on what you want for looks, performance now, or later on. the perfomance gain with just 21 cc domes will not be a great increase, but its there. I know a 21cc dome makes 157psi at sea level which is safe with +4 timing and 93 gas,....at sea level. Not to mention they cost about the same.

dragbanshee Posted January 11, 2009 Report Share Posted January 11, 2009 As fastrthnu said the vforce are ok but I think you will get the most out of a Noss head. Whats your elevation? Quote Link to comment Share on other sites More sharing options...
2001Stroker Posted January 11, 2009 Report Share Posted January 11, 2009 Definately get the head. Much more practical. Bump it up to 21cc. domes, and get more torque through the entire rpm range. Unless you have a motor that's making monster horsepower, I'd stick to Boyeson Carbon Fibers reeds. Ask Snop about it. He dyno'd those reeds vs. Boyeson, and got like 0.2hp more with the VF3's.

Ieat4strokes Posted January 11, 2009 Author Report Share Posted January 11, 2009 im at 330ft above sea level, so i could go lower than 21cc? yea i know i could save for a port job but ima wait and do the port when i do the 4 mill plus it was blown when i got it and builder said cylinders was on its last bore, id rather port some that will last me a few builds....now i just got the shee and it was stock except for the pipes..... i gotta piece it together so the wife wont notice a lump sum coming out.... i gotta take it easy as i just spent over 4k modding my zx14 streetbike, when i sell my stretched zx9, ima shoot for some carbs, new ported cylinders (cubs) 4 mill crank and some cpi inframes Quote Link to comment Share on other sites More sharing options...
