Hi guys, just wondering how many people on this forum have JUN cams in their Evo8s?

We just installed a set of JUN 264s and the car at 15 psi pulls as good as HKS 264/272 at 21-22 psi...

George for your super high out setup why not try the king of cams G/Force. 280 duration 11.8 lift both intake + exhaust. What happened to your Tomei cams ??? Not happy with them ??

 

We installed the JUNs in a customers car

I was just wondering how many people have them?

To me it seems it is only Al and Seba...

Actually, my engine is back from the machine shop tomorrow.. We are getting REALLY close to actually dynoing that monster setup
Tomei are better than HKS and JUN , in my opinion

What is G/Force website?

Look forward to seeing if you break your dyno . G/force's site.

i just want to know if i install the tomei poncam is the engine will it stall and did i need to change the valve spring and ecu ,and what is the diffrence of poncam and procam ,and u said the tomei cam is better than the hks and jun is that true,and how much is the tomei cam

thanks

 

Tomei says that you can run the Poncams with stock springs, but that is for EVo7. Evo7 has a bit different springs, I am not sure if they are that much stiffer than teh EVo8 stock springs.

The Tomei Procams are better. The Poncams have very similar specs like the HKS 264s. So I assum ethey will perform better.

Both Pon and Pro are the same price: a set of cams is $810.

I think above 8000rpms the JUN 272s are unbeatable, the Tomei have a too short duration, I wish somebody would test this though

 

i sold 25-30 sets of jun 264, and just one set of 272 (to Al)
for some reason almost all went to west coast and two sets to Puerto Rico, I guess people in west coast have heard more about JUN.

 

Has anyone done dyno comparisons of jun, tomei, and hks on the us evo8? Boost, you guys must have some dyno sheets lying around to be so sure that tomei are the best. Can you post some? Thanks.
