Awesome build man the setup gonna be nasty.
2 things why not more compression since you have E85? And why not bigger cam?
My guess is 620-630rwhp 540-550rwtq N/A Never saw a good results from this Wilson intake maybe in the future you can swap to Precision Metalcraft Intake those are SICK.
845rwhp 890rwtq 200shot
Keep us posted.
Regarding the compression, with the ProEFI I will be able to run pump gas as well, so I wanted to make sure that I did not have too much compression for a pump gas blend being in the tank. I ran 13.8:1 on my last E85 Z06 but having to locate E85 stations is a PITA when you're not around your usual part of town.
The old setup made 617/575 with this same motor, intake, and cam, but different heads, fuel system, headers, etc...and it never was on spray then. I'm not too worried about the intake manifold. It seems that any manifold that fits under the stock hood will be hampered compared to a longer runner length or blow through manifold, but I don't want any holes in the hood. They likely gain nothing compared to a nice ported FAST 102, but they look so damn good.
Pump fuel, I'm going to guess 615 on a Mustang, 645 on a Dynojet. With E85, bump both of those by about 30hp. Of course this is tuner-dependent as far as how they they want to take advantage of the fuel.
That 200 kit will send it into the 860 range for both whp and lb-ft.
This is on a load bearing dyno, not a dynojet. Not as high as I was hoping, but dyno's are just tuning instruments, we'll see what the track results say when she visits it soon. Hoping for low 10's on motor and low 9's on spray, but obviously that is dependent on the driver.
Those billet wilson intakes suck.
I think that will hold you back on that setup.
We built a c5 a few years back
440 ls7 built for 350 hp of N2O
All pro heads 11.5:1 compression
Custom nitrous cam
fast 102
NW 102
17/8-2 inch step headers
tr6060 c6z rear
It made 620 rwhp on break in tune.
Then a buddy built the same motor but used the wilson and it was 20 rwhp down peak difference from 4500-7k rpm

Interesting. I didn't think it would make any more power than a FAST 102, but I also didn't think it would make less. Dyno numbers are all dependent on the dyno, Delgado and the guys here state that their dyno does not read as high as LMR's or Serious HP's dynojets....so if I really just wanted a bigger dyno number, I'm sure I could go get one. I am curious if what you say is correct. Obviously you are talking about two different cars likely tuned at two different times, so it's not a science here, but 20rwhp is a big chunk to lose. If someone was willing to send me a FAST 102 and a fuel rail kit that I could swap onto my car to try, I'd love to validate that claim.
I may be selling my valve cover setup already, so I may sell the intake manifold and fuel rails as well while I'm at it and really de-bling the engine bay.
So what intake manifolds are available to make the best power for an n/a or nitrous car that will still fit under a stock-ish hood. I have a slight bump in the hood, but I'm not cutting it open to fit a blow through carb style intake or anything. If/when I decide to go with a turbo setup, I may reconsider my options, but for now it will stay just a nitrous car, but I may add a 2nd stage here soon.
Personally, I have a hard time believing that Wilson intake is a restriction... Although I have never tested one, we have used Wilson on our old big block stuff and they always perform outstanding..
I would have to see an intake swap on the same car, same dyno, same day to believe its less efficient..
Different cars on different days, useless data...
I'm sub'd for your progress.. 2nd kit gonna be nasty!

real solid numbers to work from and keep us posted on track results.
