Boost is just a number. I'd say around the 900-1000rwhp that they would begin to be of benefit.

IIRC when Sean@ERL came to our shop, that's not quite what he said. I've never done it before or had it performed, but never was a CNC mentioned TMK.
I would worry more about power level than boost.

Love the build Martin! Looking forward to more progress! Did you ever get fueling issue sorted?
By the way, I only have a few more things to get sorted before I get seriously rolling on my project. Won't be as wild as yours but I'm fully expecting at least an 8.5 cage is going to be needed by the time I'm finished. Might have to make a trip to Mount Airy for the cage work

Martin, based on the info you posted earlier with the compressor map, is that to say that a smaller cube (4.8/5.3/5.7) motor is going to be the best option for anyone just starting a build? I would assume the majority of us who are making plans for our first big turbo build are under the impression that a 370 or bigger is best for the S400....or at least that's what I've always thought.

In a street engine where spool, under the curve torque, not wanting to turn the engine 8000rpm or buying the valve train parts necessary to accommodate this high of a RPM, no the smaller engine is not best.
You have to look at what you're trying to accomplish and what the goal for your car is. In a street car, torque, quick spool and being easier on parts is a goal I would always strive for in any street car.
We're a couple of days away from jumping back into the thick of things on my car. Ordering the EFI set-up(I am going with the Holley after we found our fueling issue), materials for the A2W intercooler and turbo kit.
I'm also fortifying the valve train even more. The stock rockers are gone and are now being replaced with these: http://www.compperformancegroupstore...UltraProMagnum
I'm selling my spring kit as well. If anyone wants a set of really nice PAC 1207X springs and spring kit to go with it, I'll make someone a killer deal on them.
Lift will be over .700" with the new rockers, staying hydraulic. Really want to go with a solid cam, but I want to try and make the hydraulic work at first.

Going with the holley dominator efi? Very interested in your experience with this when the time comes.. It appears that this system should be ****, but I have heard mixed reviews.. I want it just because the Autotune and apparently it is very user friendly once you get a baseline tune set up with autotuner, i have no experience in modifiying tunes but I have a good understanding of how it works.. seems it would be very helpful for someone who does not have access to a dyno anytime they want to make changes on their set up..

Not sure of what power level you were shooting for but that treadstone isnt a bad cooler. I've seen 42-45 deg rise on 24 psi boost on a dyno pull over 1000hp thru the th400, thats likely 1200-1300 at motor so approaching max capacity on the cooler. On good gas the intake temps are likely fine but doing a good quality thicker core will only help. The cheap ebay ones are not good at big hp levels. Local import shop tested a 600awhp evo using identical dimension coolers, one an expensive name brand quality unit and one a popular ebay knock off. Ebay one saw 60 deg rise and lost power as timing needed pulled. The good cooler only seen few deg rise, i forget the exact numbers but it was impressive

Well guys, the A2W idea was grand, but in the end I could not afford it and still purchase all the other needed stuff.
SO I purchased a Bell 6" thick, 8" tall, 20" long core today. Good to 2300cfm. It will be here hopefully by the end of the week so Matt can start mock up on the intercooler and turbo system. I will say that the guy at Bell was awesome to work with and got me exactly what I needed. Was very helpful in determining what was best. I originally wanted a 24" long, 4.5" thick 8" tall core and he wanted to see me go with a 10" tall for maximum contact area for cooling intake charge down. We compromised on the 6" thick 20" long 8" tall core.
He told me that at low boost pressures flow is much more important than thermal efficiency. At higher boost pressures thermal efficiency is more important.
All stainless has been ordered as well as my new 5" down pipe flange. Gonna do 3.5" inlet and 3.5" outlet on the IC.
Got to order the 4500 flange Super Victor LS3 intake next. Then it's time to re-fortify the valve train and I'm having second thoughts on doing that right now too.
Jose is going to update my turbo instead. That will cost less than re-doing my valve train and give me even more power, so I'm going to let him do his thing.
