Is the turbo ball bearing? What is the AR?

Looks good!

What is holding you back from going for more? Are you out of fuel with the 1300's? Is this power what you'd expect from this setup? I think I would have expected a little more with this turbo and those cams.

I know you guys are pretty well versed in Virtual Dyno, so I don't suspect any data entry issues (and the plots look very consistent). It just seems power is a bit on the low side for a 67mm turbo at 28psi. But I'm looking forward to seeing it turned up!

I do have to say I'm impressed by the spool on this turbo with the 06 STI short gearing! I love seeing all the people going with bigger setups this year. A couple years ago it seemed like 500-600+WHP was pretty rare, and now more and more people are doing it.

I agree 20psi by 4500rpm from a 67mm turbo is really good.

We were just testing the SD ROM, so we didnt totally push it. Also we started to get some spark blow out, so the owner is throwing in new plugs with a smaller gap. We're hoping to hit 600hp when we play with the car again today or tomorrow.

spool looks more like a 6266 as does the power,something doesn't seem right.At 20 psi even on 91 should be higher with the amount of air the 6766 can move and should be way over 600 at 28 psi on e85.Not trying to knock this car just pointing out something doesn't seem right on the setup somewhere.

Maybe precision put the wrong compressor wheel

^^^Anything is possible,it wouldn't hurt to measure both comp. and turbine wheels just to be sure.

That is what I was getting at. Compared to my car it is making about the same power vs. boost but it is spooling 1000rpm slower. Main differences are that I have a 6266, stock cams, and the longer 4th gear. I am looking forward to seeing what it does with higher boost. Hopefully the top end really comes up!

but my point is with an efficient setup, with THAT turbo(same as xdrian's iirc)it should be making at least 500whp at 20-21 psi even on 91 and a whole lot more on e85.Pushing more boost to get where smaller turbos(gtx35r/6266) means there is a restriction of airflow somewhere.Just my observation.

Yeah, spooling a bit slower on a larger turbo with larger cams is expected. I would just expect to see an extra 50-100 WHP more to go along with it. I'm very curious to see what it will do with more boost.

We had this car in today and found that the head gasket was leaking coolant into the cambers, so that was probably why the power was lower then it should have been. The APR studs were only tq'd to 90/ft. New gaskets and new studs going in soon.

Also, like said, the tune (timing) was real conservative.

juanmedina, Its a JB turbo and has a .81 hotside (according to owner).

^^^thats why the spool might be better,that seems like a small hotside for a big turbo and could be choking it up top causing excessive backpressure.

Standard ARP's only get torqued to 90.

Sounds like an issue of surfaces or something else.

True the spec is only 90 tq, but most do them to 100-115 tq.

Also, a surface issue is very possible, as I think the motor was just slapped together.

I hope the higher tq helps you guys out but honestly if 90 didnt do it I forsee more issues. Might want to try the 625's/l19's

That or improperly torqued during assembly. For a turbo like that though I'd just step up to 625's or L19's.

Good work on the tune though jay.

Yeah, Im pretty sure the owner is putting in 625s or L19s this time around.

Thanks.

Get the surfaces redone. We where in std ARPs and running 34psi on a 6766 on E85. At the limits here. But the 625 studs are a great choice.
