Callaway essentially did what I did except mine was done better. I went with a Magnuson 2650, 103mm throttle body, JLT 5" intake, DSX aux fuel pump, ECM tune. Mine made 722whp/ 720wtq which is essentially, 815-825hp at the crank. I went against the norm of adding headers since I feel the stock exhaust manifolds flow plenty well at this power level. I do think that it's a simple proven formula though to swap to a larger blower instead of trying to port the stock blower and add a ton of cooling to get the same power.
 
Interesting hood cutout. Surprised they didnt put a clear cover over it like, ala ZR1.

It looks really tacky if I'm being honest. They just left an open cutout in the hood to provide clearance for the blower. I would have rather seen them use a hood with a slightly raised cowl or a visible cutout like you said on the C6 ZR1.
 
The hood is a huge turn off for me. It looks like something from JC Whittney. Does anyone know how much? It'll be a lot of money for 100 odd horsepower. Hard pass for me....no offense.

It's hideous. WTF.

Try 50 HP.

Is anyone doing the math here?!?

🤦🤦🤦
 
@No Usury .....My math says 112 hp, I have no idea what the net would be if that's what you mean
Right, sorry, was talking about the 2650's gain, which is ridiculous for what you're paying for the blower alone. Add in the ECM unlock, etc. and the $$$ really get stupid.

Is there even a price anywhere for what that 112 HP + Hole Hastily Chopped in the Hood costs you with Callaway?
 
I was going to send an email to find out, but I don't really care. I'm guessing $20K? Unless they go after "Blackwing" money and go $25K-30K, but that would be....um, ridiculous.
 
I think you're ^^^ off by half at least...come on, it's Calloway after all, just the added exterior farkles are $12k

They didn't use a 2650 but they did use their own blower which is a 3.0L. Either way, both of those blowers are FAR more efficient and cool considerably more effective than the stock blower. Sure, you could argue for less money that you can gain the same power on a stock ported blower and pullies but it will be at a greatly reduced life of the blower and it will become a massive heat pump that won't maintain its power over long distances or repeated back to back runs. I think the 2650 is the way to go compared to a stock ported/pulley'd blower even if it does cost a little more.

The price of Callaway's packages are always going to be stupid expensive though, you're partly paying for a brand name.
 
It'd be nice to see a comparison between this vs. Magnuson vs. Escalade 2650 (Eaton?) vs. stock ported pully in an endurance race or 20 mins on track. The Callaway may cool best. 2650s will be able to get the job done w/ some concern at high ambient temps or altitudes, and stock ported pully would derate around lap 6 is my guess. But it's just a guess!
