So the 2650 came in last week and we're already in the process of making our improvements on it from visual impressions and then we'll see what else we do. This blower has shown to pretty easily make 800whp; however, with my ZR1's supercharger already making that with 17PSI and 18* timing on the stock long block and 93 octane, I really think this supercharger will be capable of over 1000whp on the right setup!

For you guys that want one, I have a half dozen coming in from Edelbrock next month!

Pros:

• Really well constructed unit
• Impressed with intercooler size
• Impressed with the attempted intercooler flow with a -12 inlet and -10 outlets
• 102 MM inlet for larger throttle bodies
• Port Injection bungs - just need opened

Cons:

• Biggest issue is the choke point for the air flow above the lid. There is VERY little room for the compressed air to make a 180° turn to go back down into the runners
• Driver side intercooler outlet has to make FOUR 90° turns to get out of the coolant manifold vs. the Passenger side has to make just one big sweeping bend
• Need to measure, but I think we'll have to blend the inlet to get the last MM for the NW 103 TBs
• Need to open up the port injection holes

WEAPON-X Plans:

• Lid Spacer to provide more artificial plenum volume over the IC brick for improved airflow down into the runners
• Billet Coolant Manifold with AN fittings for rubber or braided lines and our upcoming dual HX pump setup or the larger Stewart pump setup
• Snout/Supercharger porting
• Port Injection Modification with our custom billet rails and brackets
• Griptec Pulleys from 3.5" down to 2.5"
• Custom high flow intercooler brick
• Custom Carbon Forged taller lid kit for hood/cowl clearance

Giant dual pass intercooler:


Port Injection:

Lack of plenum volume:


Plenum airflow has to make a 180° turn in this small cavern.
At 15K blower RPM, it's expected to move 1500 CFM
At 18K blower RPM it's 1700 CFM
At 25K blower RPM and more free flowing inlet, Magnuson shows this rotor pack capable of moving 2500 CFM!

So, needless to say we're going to free up a little more space to help this breath more!


Cooling Manifold Adapters:

Four 90° bends to get out on the driver side:

102mm Inlet just needs a little porting

I just made a post asking about availability on this Ben. Also not sure if its just on my end but none of the pics show up.

Fit under stock hood?

Damn you Ben, I haven't even picked my car up yet from your shop and you have me thinking about this. This is why I did not take you up on the offer to look at this 2650 last week when I was there for the dyno tuning.

I think this is pretty big for these... If you just screw around on the street, or maybe drag race, it will be fine but I'm not sure I would want to road race this blower. I could foresee some crazy differences in cylinder temps/stress.

derp... lol sorry they're public now. they auto upload private

Yes <$6K indeed!

Hood yes, but the cowl will still need trimmed I believe on the C7 just like the Whipple. VERY minimal modification and a new plastic wiper cowl would hide the little sheet metal trimming that needs done if you ever decide to revert to stock. Wipers etc are unaffected.

Haha yea I will have more next month IF you're ready! 800lb ft of torque not enough for you though?

Pressurization issues are likely only a brief point as the plenum would pressurize and airflow isn't at a constant-ish boost pressure. Once it's pressurized, airflow to the runners will be a lot more equal. The area of exposure though is the heat created when making that turn; however, again it is passing through the HX one last time to cool off, so I really do have high hopes for this one!

Ben I think the 742 HP & 803 wheel TQ will be enough for now. Nice to know though that the 2650 is there if I want more later. I really appreciate the great service and outstanding job you guys did on my Z06.

Ben@WeaponX

That power without a cam is just insane considering a heads/cam Z06 we did 2 weeks prior was 720/700ish on 93 octane. Regardless, let me know IF you want to do this in the near future. Someone will get that "R&D rate"!

Wow!

Well I didn't want to bring it up since that was likely my Z.....but since you mentioned it
I thought Jstew's build and mine were pretty similar, that is an incredible difference in power # especially considering I did a cam
Where am I leaving the apparent 50hp 100tq on the table?

Ben@WeaponX

Ls1fury

Ahhhh I must have missed he wasn't on straight pump gas.

Ben@WeaponX

yep your numbers on 93 with heads/cam are pretty common unless you go with a radical cam and overspin the supercharger to approx 28K, but still you need octane to do that. his numbers are really impressive though for the stock long block... free up some of that boost with a cam and it would be pretty insane! we did a stock long block with the whipple and e85 and it made 810whp at 23psi, and the same build with heads/cam and it made 870whp with 18psi. long story short, the stock cam is very restrictive once you start trying to push 1800 CFM through it.

dmaxx3500

how about putting it on and just finding out ,what does over stock

Ben@WeaponX

Since you can max out the stock fuel system with a couple of pulleys and an intake for less than half the price, I am primarily focusing this study on guys who are maxed out on the stock blower

mcoberly

Has anyone purchased this setup yet? If So how do you like it. I think i am about ready to purchase!

Freaked Ls3

I agree, anyone do this yet?
