I too much last night

 

lol - yeah took me a while to find the thread Chris - I emailed Japan to see what's up with the 11.8 Tomei's. And one of these days we'll get the JUN cams added to the site since we deal directly with them as well

 

Nice!. If you can let us know what you find out. If they have the 11.8 coming out soon then i just will wait for those. Also is there any news of JUN possible coming out with another cam? I mean even though there 272 is more aggressive then any other cam at 1mm i think that still could possible do somthing with there lift?

Thanx in advance
Chris

 

Chris: I spoke in person to Suzumo Koyama from Jun when he was here in Panama, and he told me that there are no plans to develop other cam spec for the evo, he told me that from their R&D, that was the best that they did come with.

 

Thanks for the info. JUN's a great company with years of experience. It makes you wonder on some of the other cam profiles if that cam from JUN themselves? But they are the only cam with the ramp up being so agressive so maybe its possible the other cam profiles use the lift to make up for there ramp?

Excuse my ignorance, but would installing pipers in an evo w/ stock turbo (10.5 hotside) and a ported head (1MM over valves, springs etc) provide any gains over an existing HKS 272 setup?

Would the head have to be setup differently for the pipers vs the HKS 272's?

Appreciate the info.

 

From what I've seen, I wouldn't expect any improvement with the Piper cams over the HKS 272 set.

With the head set the way you have it as per your description, you should not require any other changes to run any of the available cam sets.

 

There is a guy that i talked to on here through Z1 that has a 650whp car and had the piper cams. He hated the way it idled and switch to the Tomei 280's. He cant stop talking about how much more the Tomei' s perform comparted to the pipers. Now you will see a difference going HKS 280's over the 272's that has been proven already. Now how do that HKS 280's stack to the Tomei 280's with 11.5 lift and the upcoming Tomei 280's with 11.8 lift? Only time will see. I do think the Tomei 280's will provide better low and mid range over the HKS 280's but i dont think you will see much of a difference. We will see.

 

Sorry i havent forgot about you i got the cam cards and will scan them in when i get to work tomorrow.

You know what? All this info is gona be dated soon. Especially with teh Evo MIVEC comming out you will be able to run the most agressive cam profile up top and have it nice and stock down low. Then you can run whatever you want.

 

The upcoming Tomei 280's with 11.8mm lift are supposedly designed for solid lifters.
As far a practical experiences go, drove a friend's car with Tomei 270's with 11.5mm lift and again after he swapped those cams out for some Jun 272's. End of day, the car with the Jun cams felt much stronger than the Tomei by far.

Cheers

I would have to disagree. The cam itself will be the same as the normal cams expect for 1 extra lobe. Information is never outdated if you ask me. Everything is going to carry over just with a little more information. Just my 0.02

Chris

 

Ya and there is nothing wrong with solid lifters expect the fact you have to adjust them every once in awhile. At least have upkeep on them. Anyway i would expect the JUN's to perform better then the Tomei 270's. But the Tomei 280's with 11.8 will be a totally different profile. Question is will it be more aggressive at 1mm. Possibly but the JUN's have such a ramp on them it would be hard. Anyway cant hurt to try even though i did some tuning today and it really woke upthe HKS 280's. Car has never felt like it ever pulled harder then it is now and im even running lower boost. So i guess we will see what the dyno tells us.

Sorry for the bump but I am _REAL_ curious about these videos! If you can/want, please let me know if you have them and I will host them for the forum. Let me know appx. file sizes!

Thanks.
