The LT4 is strapped and pushed and poked and prodded and stretched to it's limit and you'll barely make 700 RWHP and you'll still potentially have cooling issues.

And to be frank, if you're asking about it at this point then you must already know that the 2650 is the way to go. Consistency, efficiency, potential, future mods, etc. It's the only way to go. Well the Whipple 2.9 is also a great choice if you can find one at a good price. The new Whipple 3.0 looks promising also. But why go thru all the trouble of trying to coax the stock LT4 to do something that the 2650 will do effortlessly? Nobody with a 2650 or 2.9 or any of the aftermarket blowers wish they had just stuck with their stock blower or even think it might have been better to do so.

I already know how you feel, I've read how you feel about the 2650R in every thread that its ever mentioned. I got it, you love the 2650R.

I mean come on, we all know how this works. You tune that thing, void the warranty, and you'll be stuck with very few shops that are competent enough or even willing to work on it. And they're not gonna cut you any breaks. You think you're gonna pull in there with a $70K+ minimum brand new C8 and they're gonna NOT take advantage of you? LOL!! Trust me, they'll know that you got no warranty and few options and you'll be nothing but a bag of money in their eyes. $190 oil change and we'll have it done next Tuesday or some other nonsense. Parts with an 80% upcharge just because. Nothing on this car will be cheap or even relatively reasonable if your warranty is voided.

And then when you do find a shop, guess what, they're gonna joyride the hell out of your C8.

Any speed shop that builds these cars will do general maintenance as needed. Nothing is ever cheap if you have to pay out of pocket when your warranty is voided, yet we have so many people that mod cars anyway. We accept the risk.

Clearly. There are former Maggie employees here, perhaps Blaq is one

If they are tuning it through the factory ECU then I am on board.

It's not that I love the 2650. It's more that I'm not a fan of pushing the stock blower. And many of us have commented on every comparison thread. Maybe I'm just more outspoken or I stand out more.

It's not really about the blower so much as it's about the potential and capabilities. The aftermarket blowers are just flat out better. Now if this was a Hellcat forum then I'd say keep the stock blower until you're looking to make quad RWHP numbers. 700, 800, 900 RWHP and the stock Hellcat blower, cam, and heads are fine. I wouldn't even consider a 2650 or anything at those levels. But with the ZL1 you need to upgrade. Or you'll be pushing the stock blower, it'll be inefficient, it'll have cooling issues, and you'll barely make 700 for all your efforts.

I still don’t see a problem with 700whp on stock pulleys and no cooling issues. E85 ftw.

Many others have had cooling issues. So maybe you just got lucky or you actually are having issues and don't wanna admit it or you don't know you're having issues.

So here's the thing. OP asked a simple question. Or rather, 3 simple questions. Yet when I answered him it seems like some people don't like the answer. So do people want an answer or do they just want someone to tell them what they want to hear. Because I can do either of those.


1. At the same boost level, is it even noticeable?

No. It is not noticeable. If that is what you want to hear.

2. With the improved cooling from the 2650R does it help at all for casual driving?

No. Not at all. If that is what you want to hear.

3. Is there any perceived loss of power due to the larger blower rotors at part throttle when not under boost?

Yes. If that is what you want to hear.


Now in my experience, nobody asks a question about a blower setup unless for some reason they are unsure of their own particular setup. I'm not asking anyone if the 2650 is superior to what I have (Whipple 2.9) because I know for a GD fact that the 2650 IS indeed better. Not a question or doubt about it. However, the 2.9 that I have is enough to exceed my needs...for now. When I get to the point that I max the 2.9, then the 2650 would be no better and I'll most likely be switching to something superior than both. But OP is asking about the 2650 in comparison to his setup because to me it is obvious that he has doubts about his system. Either that or he is experiencing some issues with his. Or perhaps he is considering switching. Because there would be no other logical reason to start an entire post about this when this has been debated and discussed many times. So color me taken aback kinda sorta.

So now, is the stock blower capable of 700 RWHP? Yes. Can it do so efficiently? Yes depending on many factors and many ancillary and supplementary parts. Will it have cooling issues? Maybe. Maybe not. Depends on many factors. Will you be satisfied with it? Well if you're asking about the 2650 then I would assume you're not satisfied.

Is the 2650 or 2.9 better? Yes. Hands down. At any HP level, at partial throttle, at full throttle, max boost, boost per boost, max potential, in every possible way they are better. Not one person has said "hey let me ditch the 2650 and go back to the stock blower". Does any of this mean the stock blower is trash? No.

So take what you want from it. I don't care. If money is no object then go with a full build and get it all done in one shot. If money is an issue then do what your budget allows and be satisfied. If you just want a slightly above stock HP and you will be satisfied then do whatever you want. End of the day, your car, your money, your choice.

Here's the controller needed for the c8 for tuning so I guess that's why lpe teamed up w maggi. Looks like peitz's kit use there stuff.

If I remember correctly Emilia had engine troubles at 660 hp and the kit makes 700

The stock blower has been shown to make over 900whp when ported in extreme builds, I won't argue the 2650R is a better way to get there but there's a C7 Z06 running 8.6 on the stock ported blower and there's a ZL1 running 8.9 on the stock ported blower so clearly they're capable of much more than you're giving them credit for.

I think the majority think by the time you spend the money to reach the power level say 800 rwhp you would of spent just as much as buying the 2650 . Also the convince of using 93 vs messing around w a meth is nice.

Blower porting $1300 to 1500
Heat exchanger $400 to 1000
Grip tech 2.10 or 2.30 $200
Extra capacity tank 700 to 1600 or chiller setup $1400+
Meth kit $1000+
Lower pulley ATI or I.W. $600+
Dsx flex kit $300

VS

Maggi $7000
$-1800 sale of blower

Pretty simple

Unless your using meth i don't believe its possible to get to 800rwhp with either blower. High side falls off and you will either need meth, cam, or port injection to get there from my experience. Don't think you get much passed 700 rwhp with stock high side. If you have another way I'd be interested to hear

I totally get that the 2650 is a better setup. No one is saying it isn’t. But I don’t agree with this cost comparison. It’s not that cut and dry. I’d still want all of the mods that I have on my stock blower with the 2650 except for the $1500 porting (headers, exhaust, TB, CAI, flex fuel, fuel system, cooling system, etc). I’d never ever drop a 2650 on it and stop there. That would be pointless when I can make the same 700whp and run as cool as stock with my stock blower and my cooling mods.

So the comparison for me is $1500 vs $7000. I may do a 2650 someday. But I’m doing all of these accompanying mods on my stock blower first. I don’t care if I’m spending more over the life of my car. I’m enjoying the process and that’s my choice. My money and my car lol.
