I am researching options to my kong ported stock blower. Initially I thought I would go with the Maggie 2300 because it easily fits under the hood without mods and I'm not looking for maximum hp. However, it seems I would be leaving a lot on the table.

I've searched and can only find a weight on the maggie 2650 at 105lbs. Does anyone know the weight of a stock blower? Whipple? Maggie 2300?

I am fairly certain that the Whipple requires under hood mods. I'm almost certain the Maggie 2300 requires no mods. Not sure on the Maggie 2650.

Can anyone answer these questions or point me in the right direction? Thanks.

Maggie 2650R is the best option at the moment, if you're going to spend money for an an aftermarket blower, I wouldn't even consider anything else right now. I believe the 2650R requires coil relocation.

Sorry but the 2300 will be a waste of money. From what I know the Whipple 2.9 does not require hood modification but I could be wrong. It is a good option and can certainly make more power than you need. But you'll have to spin it a bit faster than the 2650. It is cheaper tho and probably the best all around blower for the price. The 2650 is one of the best in popularity, power, and fitment right now. I would say that the 2300 should not even be considered. You'll just end up removing it and selling it for less than you bought it for which will not only be a waste of money on the blower itself but also on the install and tuning. Stick with either the Whipple or the 2650.

There are other blowers that are bigger but they are way overkill and might even cause tuning issues. Like the 4.5 and others.

If you're looking for a centri option then I believe ProCharger is the way to go.

I'd also advise to stay away from porting. Again, you'll be spending money on porting and pulley and install and tune just to remove it and swap it with something better. I say go for the kill right off the bat.

The 2650 is the best option right now. You'll need to modify stock valve covers to move coil packs, or get after market covers like the ones from speed engineering.

...so once the Maggie 3100 comes out (soon), will the 2650 be a "waste of money", too? The 2300 is lighter and perfectly fine for less extreme hp targets.

That said, the 2650 is definitely the best option at the moment, but IMO its existence doesn't mean the 2300 or the Whipple would be somehow invalid.

OEM LT4 blower with all its associated parts is 82 pounds (with coolant).

Maggie 2300 is capable of 900+ RWHP... hardly a waste of money. Whipple can do 1000+ RWHP and the 2650 even more. All three are great options. Given that most people will not invest the big money into the fuel system that is needed to get those numbers, any of those options are plenty for most LT1/4 owners IMO.

I wasn't saying the 2300 is a waste based off the size alone. And I never said the Whipple is invalid. I think the Whipple is a good option that is a bit cheaper and can still make the same power even if you have to spin it slightly more. I think the 2300 is just not worth it. I know a couple SS guys who went with the 2300 because it was a smokin good deal a few years ago. But they ran into heat soak issues and struggled at the track because of it. And some of them ended up swapping it out. So no, when the 3100 comes out, the 2650 will not be a waste. The 2650 and Whipple 2.9 will still be optimal blowers for this platform. If someone wants to get the 2300 then by all means do so. Their car, their money. their choice. I just don't see the point. I say go for the 2650 and do all the mods you plan to do at the same time.

Basically I view the 2300 as an affordable entry level blower for SS guys who want stock ZL1 levels of HP and performance and are gonna leave it alone after that. Once you start pulleying it down and trying to get more HP is when you will run into issues. Can it generate some good numbers? Probably. Is it worth trying to spin it and spin it and throwing money at it and all the headaches involved? Not to me. Would I go that route over a ported blower? Sure. But if money is no object then I don't think that is the way to go.

If it was your first blower the 2300 is a great option. However since you already have a SC just go right to the 2650r. The cooling is superior to the 2300 and as stated above the 2650 is the choice of most at this time. I know everyone thinks the 3100 is going to be the big boy on the block and should out perform the 2650 its still going to be the best option for a stroker setup or heavily modded lt1 or lt4. I'd still choose the 2650 over it at this time.

[L78toLT1]

Is the Whipple appreciably heavier than the 2300? If so, that's something to consider, especially if you spend more time on the track than at the dragstrip. With the mods in my signature, I have no heat soak issues at all. IMHO the Maggie 2300 may be the best option under 700 whp. That being said, I'd probably go with the 2650 if I were starting over.

The way I kinda see it:

2300 - Mild builds like a bolt on SS or bolt on ZL1 retaining stock cam, stock heads, stock displacement. 600 (SS) to 800 (ZL1) RWHP range on pump gas depending on setup.

2650 - Moderate builds like a bolt on stock displacement ZL1 with cam swap and ported heads or bolt on stock displacement SS with cam swap, ported heads and beefed up internals. RWHP range of 800 (pump gas) to 1000 (race gas) depending on other mods, tune, and fueling.

3100 - Heavily modded like a fully built larger displacement ZL1 or SS looking to push 1000+ to the wheels on race gas/E85/meth depending on setup.

Does anyone here know for sure how much HP the stock LT4 fuel pump will support? HPE only said "not 1000 hp". They chose the 850bhp/750whp pkg. so the stock pump would have a little margin to work with.

I have been speaking with a few well known shops around the Midwest because I will be doing a 2650 build in 2021 and this answer below is directly from one of those shops when I asked the same question about the stock LT4 fuel system-

"The entire fuel system is done at around 800RWHP. The low side is tapped and the injectors are tapped at that power level. With a low side and injectors you can make about 850RWHP before the high pressure pump itself is done."

Interesting post as I am thinking about doing the 2650...Note: I have not done a baseline dyno yet but assuming around 540-550rwhp stock...mine is a manual.

So if everything on my ZL1 is stock (other than a Roto-Fab) what RWHP would I expect on pump gas with a 2650 install.
Same question on 100 octane race fuel?

My Shop is saying around 700rwhp on pump gas???
