Hmm, seems to me it wouldn't matter...
My reasoning is: Coatings may have a higher standard deviation than say a machine that over bores... but I'm no expert on coating procedure. For all I know it could be an exact science far superior to block boring!
Speaking of boring... I'll be...
Shouldn't you also have the thickness of the coating in mind when having the block bore matched?
Something like a thousandths of an inch the coating usually adds?
The nut is just a locking nut... the bolt it's on can be rotated left and right. (Left loosens the spring, right tightens the spring.)
Should be a hex bolt, or allen-head bolt.
hth.
Well I don't drive the car more than once a week, if that... and wanted to have some head room to hit 600hp w/o running out of injector.
Looks like 680's will be going in... should make tuning a little easier compared to 720-750's at the moment.
I think I'll run a dual feed to the rail first...
What I've learned is the larger the diameter, the more control over lower boost levels.
(more air being bypassed the turbine.)
On most applications... big motors and BIG turbos means larger wastegate(s).
The rule of thumb is "Run half the max boost pressure spring intended on running." (If you...
(06:40:50) Howard (Blackdevil): I used 780cc's (Delphi Injectors).
:) Thanks for chiming in, Ant.
I think I'll get some 680's from a fella on SF and try them first.

Part 1:
I was reading up on injectors, specifically RC "720cc" injectors that Genna ran in the red car... but all I see on HFP for RC's are 750cc.
I need a set of injectors to support 700hp MAX, with usual workload to do 600 daily.
Part 2:
I'm running a VPC with a 550 chip, but I know...
Yes.
That little bark you hear before the bov opens is technically surge.
The pressure change is so fast, the bov just cannot react quick enough.
It's normal though, as long as it's not prolonged you'll be fine.
