opening is exactly the same size as OEM where it meets the rubber radiator duct.

Yes the boost control is dead on using the electronic bypass valve. The valve is actually like a throttle body, except the internal spring holds it open all the time, then the ECU commands it shut for desired boost.
We utilize many different boost control strategies, RPM based, MPH based, boost by gear, manual switch, time based etc.. we have lots of control with this setup to limit boost for traction etc.

Wow, this got quite the response.


I look forward to what Chris @ Crawford comes up with. Chris - Can you tell us if the blower portion itself is roughly less, more or the same as the aftermarket blowers (Give or take ~$6k)

The lower blower itself and the upper lid with intercooler bricks are approximately $7K.

The 2650 is significantly more efficient than the whipple

current LT1 418 built motor number is 1150 whp at 19 lbs.

I highly doubt the same can be done with a Whipple 2.9

I think TVS showed test flow data of the 2650 to be even more than a Whipple 4.0

If you want to go big you buy the 2650 Maggy Stage II has much more CFM Not the same as the ZR1 2650.

It you want to take advantage of the higher output of the 2.65 the build costs go way way up! All builds need headers and a Good hi flow intake to support any increase in blower size . You need low side fuel support. A new hood if your going to the GM's 2.65 on the ZR1.
Edelbrock has one just out you cut the hood but the Edelbrock blowers are not known to be great performers. So I would wait for results from others on it.

You mentioned low side fuel support, is that for the 2300 Maggy as well as the 2.65 or just the 2.65?

Full electronic boost control with closed loop wideband port injection and flex fuel capabilities. All bolt on and plug and play.
That's what I'm talking about. Looking forward to seeing the kit hit the market.

I'm running with the stock fuel supply. Also running the 2300. I would for sure go 2650 if I was wanting bigger power. I plan on less than 800 rwhp
which the 2300 does nicely. My personal goals are less.

The 2650 is a great thing you can go 1000 rwhp plus more but the costs add up for the supporting stuff needed. The hood cutting is another.

The potential for stuff breaking, cams, fuel supply guys wrapping up 25k. I'm more DIY for around 8k. Picked up another 2300 and 2 ARH coated with cats for 6600.00
Halltech Intake, ZR 95 tb another 900 plus tune your done except I see big value with the DSC controller as well. Also because I 'm doing two cars 1 A8 1 M7.

We do have in-vehicle testing going on right now. It is more of a max effort stock bottom end LT4 setup to really see what it is capable of, and we will certainly share all the numbers soon. We also are going to be testing with a built engine 416" C7Z soon.
We have our Big Boost LT5 ZR1 pulley kit, that can also be used with our LT5 conversion kits for the LT4 cars getting the LT5 blowers.

do you have a pic too with the hood open? On the z06, with the lt5 blower, the cowl does not need cut like on the whipple 2.9 does it?

Not that much taller in the back as you can see. Mostly at the front. No cut to firewall.

997.6 whp at 21 lbs, some cooling down... it made 1k whp. This is no low side fuel and stock motor with cam only. This is a game changer!! I canít wait for my numbers on a LME 416, Crawford Racing Port Fuel with Fore Triple and porter blower and maybe 102mm throttle body. Shooting for 24-25 psi
