Background:
Started out as a 2009 Corvette ZR1 JSB with pulley, intake, snout, and tune. The car made 621rwhp on this old setup with the LS9. Didn't want to go the route with the LS9 because I was looking to make an easy 1000+rwhp on boost only. The car is being worked on over at Powertech Performance. Joe at Powertech Performance has always been very good and quick doing the work over there with the car on the previous setup. I've seen a lot of ZR1 builds only making between 800-900rwhp and few over 1200+rwhp on spray. Considering that setup would be maxing out everything the LS9 is capable of doing, I decided to go another route. With the RHS 427 and the YSI Centrifugal supercharger, it would be much easier/more reliable to make 1000rwhp+ boost only. The build has been coming along very well and I will continue to update it here whenever there has been progress to the build. Hoping to make at least 1000rwhp on e85 with this combo. This car will see a couple 1/2 mile events and maybe some 1/4 mile in the future. This is not the final stage of the build. It will go under multiple stages throughout the time I own it. Thought it would be interesting and unique to do this build on a ZR1.
Future upgrades/possible upgrades:
15" wheel/tire conversion in the rear
Powerglide transmission
Computer ECU management
Nitrous kit
RHS 427 Block
Coming together
LS9 is out
In with the new
ARH 2" Headers
Coming back together
Blower is huge! (YSI V7)
Gauges are in Wiring getting all finished up Still waiting to have most of this powder coated black. Looks pretty clean
Coming along very well. Eventually most everything that you can see will be powder coated black. The red lettering on the MSD intake will either change to be black or blue.

in for results, is that an A&A secondary/direct drive setup?
seem like a lot of boosted guys going with that MSD intake setup. curious how they work out.
Yes sir it is. I've been told the MSD intake can handle much higher amounts of boost than what I am putting into it. It should keep the intake air temperature down too.
Will be interested in how the MSD does. I mean they are having a hard time staying together on NA setups, let alone 20+psi. Definitely interested in the results/reliability of the MSD.

MSD has held for a friend who has been running 22psi from his ysi.

lsxmag did a test with it at LME and it held 30psi just fine. I guess we will have to wait and find out
i believe JBSblown swapped his ls3 intake for the MSD on a 850whp c5 and found minimal gains with something like 10whp-ish mid range gained but he also had a small blower totally max'd out so not really a great comparison
Brandon, if you don't mind me asking, what's the
- static CR?
- cam specs?
Regarding the MSD, based on my experience on a NA LS7 for 8 000 miles or so, I'd be prepared to glue the top and lower halves more or less permanently together for the FI application, at least around the injector recesses where the original seals don't seem adequate.
Personally, I'd be very tempted to glue the halves fully together, just like in the LS7 oem intake, and with the help of those three supports in the center, again just like in the oem intake, there could be a fair change of it withstanding desent amount of boost.
You're right, he's probably only at like 2 years and 15k ish...
They haven't even been out for two years, so it is a bit hard to believe that.
My point was you see post after post of NA people finding them loose, and having trouble keeping the shells together, without boost. Fast intakes come apart, and 25+psi stock intakes that are more robust than the MSD come apart. I really hope the fast works, and holds up, as it is a cheap intake if it does compared to the $1700-4500 for other intakes, but based off how they are constantly getting leaks on NA cars, I would have a hard time going for one right now on a boosted application.
That regulator (position)...please tell me more...

Be very very careful with the regulator in that position. At least without any support bracket.
Or let me put this other way: what do our forum vendors of fuel rail kits recommend when having regulator at the end of aluminum rail and more or less vibration from the engine...
This one has been hanging out in this position for ~ 2 years.
Was it supported?
If it leaks, it's not fun. If it doesn't, then fine.
Just ask from your builder/and/or fuel rail manufacturer. Fore I guess?
I would not do it that way. Based on a feedback from one of my local dyno folks. They have seen it, but again, it depends (support/position/forces/material/etc.).
