I wanted to do a quick recap of my experience of having a Z06 Supercharger installed on my 2015 Z51 Stingray.
I bought the used and already ported LT4 supercharger "complete kit" (Blower, Heat Exchanger and Water pump, LT1 to LT4 adapter plates, Z06 balancer, Z06 tensioners) from a forum member who bought it from a Z06 owner who had a Procharger installed. The used blower was from a 2016 Z06 with 900 miles on it at the time of take off.
I took the car down to Weapon X Motorsports in Cincinnati, OH. They do so much work with C7 Corvettes, 6th Gen Camaros, and other LS type engines, it made sense to have them do the install. I was right! It was an awesome experience all throughout the entire process.
Here are some pictures taken during the install.





One of the main reasons I chose to go this route (vs. Procharger or Edelbrock) was to make it look as factory as possible...and I believe it does!




I wanted to change the wording on top of the supercharger to something other than "LT4 Corvette" So I contacted Emblempros.com and had custom cover plates made!!


Although I bought a "complete kit" that included the following parts....
1.) LT4 Blower,
2.) Heat Exchanger, Water pump and Reservoir
3.) LT1 to LT4 adapter plates
4.) Z06 balancer
5.) Z06 tensioners

The install needed a bunch more parts and accessories to complete the install...For all those contemplating going this route....Here are all the items that had to be purchased to make the install complete:

1.) Z06 air intake. I decided to go with a Halltech intake.
2.) New Brisk Sparkplugs
3.) LT4 MAP sensor
4.) Custom LT1 to LT4 MAP and IAT Sensor adapter harness
5.) Gates Supercharger drive belt
6.) Various fittings and bolts.
7.) Coolant for Heat Exchanger
8.) Rubber hoses for adapting to new PCV system
9.) Custom 12V relay and wiring harness for Z06 intercooler pump
10.) Supercharger oil
11.) Modified LT4 Valley Plate
The stock fuel system was not quite enough so....
12.) Z06 Fuel injectors
13.) Z06 High Pressure Fuel Pump

Final before and after Dyno numbers are quite impressive!!!


610 Tq / 570 Hp at the wheel! or around 732 Tq / 684 Hp at the crank
The car drives fantastic and has amazing power down low...It is a different car! I love it!!!
The total cost was very similar to having an Edelbrock Eforce installed....with far more power and a totally stock look!
All in all, I am very happy! Ben, Blake, and Jeremy from Weapon X Motorsports are fantastic!! I am sure I will be back down there for more upgrades later in the year....

Great post, managerman, and the SC looks awesome (much better than the E-Force, IMHO).

Of course, the dyno numbers aren't bad either! :eek:nthego:

I like your new torque curve, not only way higher but the fact that it peaks at such low rpm's...must feel great.
The power down low is scary! Can't wait for much warmer temps. Cold tires and that kind of torque don't go well together.

managerman, another outstanding mod completed to your C7 masterpiece and this one is not for appearance only raw pure torque twisting horsepower. :triumphant: You may have to invest in a few sets of rear tires. :wink:

I assume the heads were not changed. If not how was the difference in compression compensated for?

COOL none the less!

Very cool modifications indeed! Are you planning to perform any of the internal engine modifications to bring it to the LT4 level or higher? Titanium intake valves with adjusted seats, different cam etc.

More HP is a good thing!!!!

Correct. Heads not changed. There was no compensation for the higher compression. The higher compression results in higher torque and horsepower numbers vs the LT4

Not planning on doing any other mods to the engine at this time. Pistons are good to 700whp..everything else should be good. I wasn't going for a crazy HP number at all. Very happy where it all ended up.

Thanks!

I totally agree about maintaining the stock look under the hood (looks great).. Speaking of hoods, are you still running the stock Stingray hood..?
The Guys at Weapon X look like they know their stuff..!

What kind of $ involved?
All in under 8k...but that included having to install Z06 Injectors and High Pressure Fuel Pump which was 1500.00.

Yes..Still fits nicely under the stock stingray hood! and yes....Ben and his guys at Weapon-X are top notch!

Nice upgrade Matt, looking good.
Thanks Norm!

I would wonder if you are going to be able to get your car smog in California or in any other state
Not sure about that...but luckily I do not have to worry about it since Ohio has no emissions testing at all.

Managerman, it was 81 in Cincinnati today. Did you get to put any heat in the tires and put that power down?
We got out for the afternoon. EVERYONE wanted to race. Had a WV racing GTI i think pull up beside us. He looked at us and said. Please go first. I want to hear that V8. That was cool.

Buy the way. That is the best sleeper I have ever looked at.

Thanks!! It was 75 in Columbus and yes...I went for a 3 hour drive! The smell of rubber burning was in the air...lol. I had a few people pull up next to me, but they had no interest in racing..just wanted to get a closer look at the car and give me the thumbs up.

It was a beautiful day for a drive!
