What everybody has been waiting for.

I don't understand why they'd measure lift in metric, yet inexplicably report duration measured as XX inch of lift as opposed to 1mm lift. What were they thinking? That will make it difficult to properly compare effetive duration, but ah well.

Mode 1

- A little less lift than the HKS sets, but with presumably a more aggressive ramp design
- Timed like an HKS set at +3/+3
- My guess is slightly more duration at 1mm than an HKS 264 set - street oriented cam



Mode 2

- A little more lift than a JUN set, a little less than a Revolver set
- Also timed like an HKS set at +3/+3
- My guess is roughly the same duraton at 1mm as an HKS 280 set, a little less than a Revolver set

 

Well theses cams look a lil better then HKS 280's , Jun 272's

But overall without testing on a car it would be hard to guess which one is better.

I still say that the best overall power would be in the JUN 272 the way they are made is far more better then hks or revolver even with the higher lift on this set.

Hey Geo why dont you ask Eddie to test out the cams i know he's got the hks in his car now ask him to test out the JUN'S and Cosworth. He will pick up over 30 whp by by running the jun cam's i know for sure.

 

If anybody can make the power it would be the man Rolo if i spelled that right.

 

I am going to be building my evo up and want to be able to rev to at least 8500, what else is needed with these cams.

 

A big turbo kit, a valve spring kit, big injectors and fuel pump, all the typical supporting bolt-ons, a good means of electronic tuning, preferrably a built reciprocating assembly (rods, pistons, etc.), and race fuel or at least methanol injection.

 

I was just talked what else needs to be done to the head as far as springs and such.

 

You would need to get dual springs and retainers you can go past 8500 with just that but your runing a risk of hurting the values to much stress after a while they tend to bend a lil i just replaced 3 bent values when i redid my head.

The best thing to do to run it past 8500k and safely is to get the head redone with a stage one port all they do is refresh it open it up a lil or you can go anything past that up to stage 6 with the 1mm port if you really want to rev the hell out the motor get a stage 7 with the 2mm port bring it up to 11K that would be sick i dont think no one ever going to do that.

 

are they available now?

 

m guessing they will be pretty good just form the name!

but thats not everything i know!

Hey Julio, Eddie will be putting cosworth cams on his new setup soon, ill let you know when the car is ready and goes on the dyno, Eddie and i spent alot of time last weekend working on it and the car should have the motor and tranny in hopefully by saturday

 

Sounds good. That 40R should be sick with his setup with the spary on top i see him running 9's on his second pass.

 

The car should be a 9 sec as it was, it trapped over 140, remeber its still full weight

 

Even if you build up the head with a better valvetrain, the stock bottom end is not going to appreciate being spun up to 8500 rpm and will most likely revolt sooner or later.

I know who made these cams...
