Can't run another year down on power... And no way we are taking a crack at custom cams again.

Jun cams on the way. I sure hope they work. Now do I put them in the old ported head, or start from scratch.

^ Finally, someone who will be able to tell us how the JUN cams do in real life.

I don't care which head, as long as we have some measure of the difference they make.

Fingers crossed its not just more money into the R&D pit. To save turn around time we are getting another stock head. We will either put them in the old ported head, or have the new one modified when these are fitted.

These are the 9.5mm lift units. Supposed to be here in 7-10days.

I had the same trouble just trying to ask questions. Never could extract a meaningful dyno from them. I'm sure they'll just show up without notice.

They were really good with answering questions before I placed the order, ask a question and by the next day I had a response, but nothing now. They claimed six day shipping, so far I am six days without shipping info.

Hey Jason, contact Chris Rado at World Racing, he's a Scion Factory driver and has lots of great contacts from JDM to USDM. One of his main supporters is Brian Crower of BC Cams, they make all his custom pieces for his Scions. His site is; http://www.world-racing.com/ , and he is one really great guy to work with.

I contacted BC a few weeks before ordering the Jun units, I heard a rumor they were going to build Yaris cams, but all they offer is a regrind. We have already been down that road with a well known Runoffs winning engine builder, with limited success. The problem is none of these guys are going to spend the time to develop a cam maximized for our needs - we have rules we need to meet that don't apply to the normal consumer - without a lot of R&D money on our end. Most people won't be shopping for a max lift .390 cam, using stock fuel injection, with limited port work and a stock bottom end. Welcome to Limited Prep Prod class, its a cheap engine build. :)

Buying something like the Jun cams, that supposedly has the R&D behind it, is a less costly investment than starting from scratch. If it works.

It took some poking, but I now have a tracking number. Fingers crossed it all turns out well.

Good luck Jason, this is one reason I left SCCA for NASA, the rules restrictions were getting to be too much! It only took me about 23 years of beating my head against the wall to figure it out and I was just running IT.

Any chance you could take a rubbing of the intake face for some measurements? I'm still not having much luck reverse-engineering the mounting hole dimensions for the outer two bolt holes using only pictures. Lens distortion is a real bastard when trying to project geometry, and the gasket--well, you know. =/

I will try.

I have a spare intake manifold I could loan you if that helps?

Well, I think a rubbing would be cheaper to mail, but the intake would give me a chance to get the other mounting locations as well. Could you get a shipping quote for 49426?

Did you sort out the communication problem with Jun? Or did it just show up at your door?

I think their normal business practice is to just ship it... I was able to get shipping info by escalating it via Paypal.

HAHA, oh well, at least you got it.

So are you just doing the cams or are you doing valves too? And have you decided on what head you're putting it into?

The rules allow us to use alternative valves, but we do not get to go bigger as a Level 2 prep car, so there is not much point in replacing them.

I am going to use the head I just pulled last week, all stock with 1200 miles on it. We will port match, deck the head, upgrade the valve springs and do a five angle valve job.
