what cams for turbo race car?
#21
I am currently running a Webb Cam. I also thought they were good to work with.
Is your motor buillt to handle the extra rpm? How much port work have you done? Any flow testing? What about gearing? Brake booster?
The answers to those questions will help you determine how radical you should go.

Megacycles
Although the catalog (on the website) does not show Mazda Miata, give them a call. Integralcams sold the profiles to them, look to spend 700 or so with core.
Megacycle Cams
I used to have a set from Integralcams, now I regret I got rid of them as the company IC went south.

im running integral cams, they are out of business not, and were bought by another company, if you search you will find them, they do motorcycle stuff. they may make the cams for you though as the bought integrals grinds.
i am running
R3 intake .495 lift 292 duration
R1 exaust .455 lift 282 duration
i think those are the specs. i dont have the paper right in front of me. for the people who say cams dont make any difference are talking out there *** from no experience. I have talked to someone with a nearly identical engine setup,and turbo set up and i made 30 more horse and like 5psi less. and the main difference was that they had no cams.
i run a GT3071R and made 418 whp on a dynopack, at 18psi at 8000rpm. this is a race car and i idle the car at 1500 rpm. i had to mill clearence into the head so they could have room to spin, and convert to shim under bucket

The good thing about webcam is that they do rewelding so you can get the cam ground without changing the base circle. Also, read their disclaimer on the ordering policies page. That is the kind of business I like to give my business to.
And subbing because there is more miata cam information in this thread than any other one I've seen.

True that! cam info is relatively scarce.
I have a set of webcam 505 +2.5 cams that I am going to run in a jdm GTR motor but for my other motor, I picked up a bp4w head and would like something a little more aggressive.
Are there any aftermarket solutions for the VVT head?

Viperormiata- What member did that dyno come from? I would love to look more into those cams, that video sounds fantastic. I remember the owner of that car in the video wasn't too happy with them though and ended up selling them, and it was running rough which is probably why is sounds so lumpy. I have emailed kelford about them in the past, I'm very suspicious that they can actually be ran with the HLAs like they claim. Its a ton of duration and lift over stock, no other manufacturer claims such aggressive cams can be ran with the HLAs. I wonder if the 400whp+ dyno car was using solid shim unders?

here is my dyno graph, now keep in mind that i was running on a 14psi waste gate spring and it was creeping to 18psi. I had no boost controller holding the gate closed to the desired level was reached. but you can see that the cams i have pull all the way to 8k, i should have kept going to 9k but i reached my goal of 400hp and the weather was shitty so i called it a day. i think these cams have more in them.

i added a ball and spring manual controller and brought it up to 20psi to get it off the spring, it helped out a little with spool. but my plans after i fix my drivetrain is get a aem tru boost on it and bring it back to the dyno, 25-27psi on race gas and 9000-9200 rpm. the cams are degreed in now, but i wanna play with the gears and try to dial out some overlap and build some more compression.
