Update #4 in Post #2: PWR race radiator received, Dry-sump paid for and shipped, still no ECU feedback from Haltech yet and x-over manifold is beginning to look like vapour-ware so I'm researching making our own x-over manifold for ITB.

It is like waiting fro grass to grow in a drought ............

Sump was 30-days late, crank is a PITA and don;t ask about the effing manifold - its has been "coming" for months.

I have inlet flange-plates digitally scanned and can cut flange plates tomorrow but can wait a bit longer for Jenvey to sort themselves out before pulling that trigger ....

All things come to he who waits is the current mantra

I get this kind of headache all the time at work. Order stuff from a vendor. They tell you it will take 11 months. So I order it. Schedule it to be install during an outage 14 months away. So that I have a 3 month cushion. Call the vendor 12 months later why I haven't gotten my part. They say they haven't started on it yet. Tell them the next call will be from the corporate lawyers. The part shows up within a week.

When it's my own stuff. It seams even worse. I feel your pain.

4th Jan Update added, all the JWT stuff finally arrived .... crank, rods, pistons, pins, hi-rev valve gear/shims and a shed-load of other stuff.

Donor engine coming apart in the next week and then block/crank/pistons off to the machine shop and heads to the flow-bench guy for a tidy-up.

He has an impressive resume and gets a very positive rap, so I am confident in his solution.

Budget will likely take a bit of a hit, but you can;t take it with you !!

Initial flow-bench results are in .........
Inlet @ .500" lift = 304cfm
Inlet @ .600" lift = 310cfm

310cfm = ~450hp

To get our planned 500hp, we need 340cfm @ .600" lift ... so the porting tools are now out !!!!

Focus needs to be on both inlet and exhaust porting to get to where we need to be.

For anyone looking at NA VQ engines, there is no way you can flow enough air to support more than 440-450hp at the crank ......... regardless of inlet manifold - the heads simply will not support more flow than that.
