There are a lot of people on here with Maggie 2650s (myself included) and a few others with Whipple 2.9 and one or two working on getting the new Whipple 3.0 up and running. Apparently the new 3.0 comes 'ready for port injection.' In my case I have a Whipple 2.9 sitting around at home with Crawford Racing port injection mods already done to it but didn't put it on my car...it was a rabbit hole I decided not to go down and getting a new 2650 was a better path forward. The 2650 has some pretty solid intercooler bricks which will be a big help for the ZL1 but either blower will definitely wake up the LT4 and add around 150WHP with little to no additional mods (maybe a JMS BaP). At that point, the stock fuel system is pretty much maxed out. Maggie prices go up at the end of the week apparently....

Thanks for the response guys.
I am looking at upgrading to the 2650.
Nothing invasive just Headers Tune up for 93 octane.

The 2650 is a beast of a supercharger but it doesn't start showing its advantages until your north of 850whp. Look at shops like LMP, LMR, and RPM. None of them use a 2650 for builds making less than the power mentioned above.

I would find a ported stock blower...then do headers with flex sensor and run a E50 blend. You can find guys selling Jokers or Kong port blowers for 2500-3k. Sell your stock for 1600-1800. Best bang for buck you will get on this platform.

uhhhh i would say the first question is are you talking about the 2.9 whipple or the 3.0 whipple? Even though they are only 0.1 apart, they are in different leagues, in terms of performance.

This is one of the most discussed topics here. You won't see a lot of improvement by only adding the [Edelbrock or Magnuson] 2650, headers and tune [maybe 100-120hp], which will cost you something like $10k incl. labor. You would probably benefit from a larger throttle body though, 9x should be fine, which adds another $750.

KingLT1 (above) can guide you to a lot more power for a lot less money, but it depends on where you think your car will end up. If you're like me and you know you'll keep wanting more hp, then a 2650 is a wise choice. I started with heads/valve train.

Its funny I called LMR about what to do with my 2650 when I was at like 700 to the tire. I asked what I could do to get a tad more power of my setup and they literally said to put the stock blower back on...

Stock blowers hit harder, so depending on what kind of driving you're looking to do, it might be good to take that kind of thing into consideration, too.

This is true and I could make a case for either direction.

Stickier tires(555r2) and Ethanol? I am probably choosing a ported stock blower. This leaves money to allocate towards fuel system upgrades for more E.

Limited to street tires and 93, the 2650 could be the better choice with the softer hit and better cooling since these LT engines are octane limited on 93 and the IAT vs spark table needs to be conservative.


Back when you could get a 2650 for 5-6k you could make a case that it's the way to go in most cases. Now, it's not that easy because the cost savings by buying a ported stocker and selling stock vs buying 2650 and selling stock is a wider gap and leaves more money on the table for something like a Toohigh PSI port injection system.

The fuel system is the biggest hurdle on this platform. So a port injected, ported stock blower setup on E85 with all the fuel vs a 2650 on stock fuel system and 93 for around the same price, I think I would take the stock blower direction.

Then the caveat is setting up the Port Injection properly. As you and others have found it's not as easy as some have made it out to be. Once dialed in and functioning properly it looks like the cats meow, but I can see some still wanting to stay DI for the time being even though it costs a lot more in 2023.

Either way it's not super hard to make power in 2023. There is no wrong direction for the most part. If ya like the 2650 and want something different, then go for it. It will give you more room to grow if need be. The main thing is we get out and enjoy are cars and not bash each other's setups on the internet.

King great Information thanks for sharing

Absolutely agree with everything.

I think, if you're serious about being effective with your money, there's a lot to consider, and, perhaps, a level of being honest with yourself (probably most important) as to how far you might see this endeavor go.

I considered as many factors as I could conceive, and at this time, this made the most sense. There wasn't an X-port (I know there are other equivalents, too), but I didn't want a blower ported within an inch of it's life (apparently), and still wonder how much, if anything, I'd be losing with the cooling (and maybe that's blown out of proportion for my use). I considered my use and what I would enjoy using the car/power for. I knew I'd be far below the potential of a 2650, but knew I could benefit from some of it's attributes.

Regardless - King's on point, as usual, and IMO - being as honest and realistic as you can be, with what you want now, and in the future, is a path that you can plan for that points toward success. Why spend money on the same thing more than once? If you already know you want more than 1000-HP, spending money on a 1740 is probably not that great an idea, and maybe it's just best to bite the 2.9/3.0/2650 bullet. I'd summarize by: start with an expectation; determine what it takes to get there; and get to ordering parts.

This is true for the most part but a lot of people don't know exactly where they want to end up. Some of us haven't been in an SS or ZL1 that's 650...700...800...900whp much less 1,000whp.
I'm personally battling with what's best for my set-up as well. It's not an easy choice

Has anyone used the Whipple? On a ZL1
