Your site mentions "you will need dual springs to run these cams", I'm assuming GSC beehives will work fine though?

Should installers be carfeful to check piston to valve clearance w/ these?

Just trying to get some answers before I change out my GSC S2's.

 

I have the jun 272. Do you recommend me switching them
Out to your cams

 

These are very aggressive so I recommend the Duals. What pistons are you running? Yes, You should check clearance. I would imagine they will work with anything aftermarket though as we have not had an issue yet. Most if not all aftermarket pistons have a larger valve relief area than stock.

Wiseco HD's and +1 oversized valves.

 

info VS the br272 cam????? how much laggyer are these VS the br272 cam. i like my cams but if you and dave made some updates and that are acceptable then i want them. maybe a graph of each would be best???

 

emery are you going to be making a set for mivec equipped cars we really need something like this for us evos with big turbos and extreme set ups.

 

i have emailed emery and the answer was NO unless he changed his mind, id be in for some also

 

I'm curious about this answer.
Emery see below about build. Wonder what a comparison would look like vs the Jun and these cams. I know my Juns continue to pull all the way to 9500 on pump.

 

Do these cams come with a cam card?

 

Bump this up. cant wait to be running these cams

 

The Kelfords don't need to be degree'd, do these at all?

 

No they will not come with a cam card. No specs will be provided.

On both cars we tested them on they worked very well straight up and did not need to be degreed.


As far as the pistons they will work with without hitting goes, The only thing we have tried for sure is Buschurs 10:1 pistons. They do have a pretty big valve relief though. If you purchase these cams I would suggest checking clearances upon install.

Sorry, We will not be making these for Evo 9's

Yes Chris, These are sitting in your car now so we do not run out on you. Yours and Alex's car will be running them. We hope to see both cars go well over 700 whp on our dyno with them.

 

What exactly is the easiest way to check the clearances? Install them and see if they hit the valves by manually turning it over? I'm running the Wiseco 1400HD standard bore pistons with stock valves.

Thanks Em.

 

That works but you will need a solid lifter at the correct hight to make sure. I really do not think they will hit I just know they are very aggressive.
