Hot/muggy isn't really going to matter with either supercharger driving to or from work. You will have the same air flowing through the heat exchanger and more then likely air temps between the 2 are not going to be drastically different in that situation. Where the 2650 will shine is on it's ability to recover faster after a hard run and maintaining a cooler temp at the top end of the pull. Any setup NA, PD, Centri, or Turbo will make less power in the heat compared to a cooler day...especially on 93. Here is where E85 comes into effect. It allows you to set the IAT vs Spark table higher because it burns cooler and less detonation prone. Very beneficial for hot climates.

Some options for better cooling....may or may not be needed.

Interchiller
Bigger heat exchanger
Thermal reduction plates
Kong porting

The caveat is how much do you invest into the stock supercharger before it makes more sense to just grab the 2650?

I was just saying if you are looking for 730whp and to rip off a high 9 second time slip, the stock LT4 has done it with bolt-ons and flex fuel. Now if you are trying to bracket race or road course that power level, then you might end up spending enough money on the LT4 cooling mods(to keep the car consistent) where it makes more sense to just get the 2650.

Don't want you to think I am saying NOT to get the 2650, it's just not needed for the guy that hits the track once or twice a year to rip off a 9.9 1/4 mi pass and call it good...all comes down to goals.

I understand what you are saying. My most important thing which ever way i go is it needs to be dependable and go on trips if i so choose. Last thing i need is to have to listen to the wife telling me i should have left it alone

Fasterproms and CPS are both working on project with the 2650. Given - Fasterproms in the Hot Rod kit on a 427 LSX combination in a Caprice, but in terms of efficiency, it sounds like they might be reporting on some of that kind of data, if anyone's curious. I think CSP will be going full send in their ZL1, because I think they've got a TS 427 they're going to push with the Magnum, so I think that will be interesting.

Just FYI - though, I bet you already knew

I am using the LT4 blower on my other LT1 and I expect it to be pretty similar to the Maggie on my Camaro into the 700whp range. In fact I am going through almost the exact same mods except using the JRE smooth idle cam on that car (and not removing the cats). On the stock blower it seems that the easiest way to up the boost is by using the ATI lower pulley and using an overdrive pulley. My car is supposed to go in next week to get the install done (blower, cam, pistons, e85, hpfp, injectors, ATI balancer/lower pulley at 5% overdrive)...I expect it will be around 7-8psi and 700whp.

Above that point, I think heat will become a problem for performance, unlike the Maggie.
If you go to a 10-15% overdrive pulley should be right in the 750-760whp range...it can be done no doubt. I agree with you however, doing so will not be nearly as Efficient and depending on how you drive heat will probably become an issue. My goal was only to be much more powerful than the Z because I am rowing the manual in that car which means any chance of a solid ET was out the Window.

Its all good.

Btw - Since this thread was talking about the comparisons of the 2650. We see that the Edelbrock can get to 1000whp with port injection.

You can also do the 1000whp without port injection in the Magnuson 2650. Here is what They are doing with the Vette (same motor).

The combination for the build is as follows:

Magnuson Heartbeat TVS2650R supercharger upgrade kit
Magnuson 103mm inlet upgrade w/ 80mm pulley
Vengeance Racing CNC ported LT4 cylinder heads
Vengeance Racing Stage 3 LT4 camshaft kit
Nick Williams 103mm throttle body
Halltech Systems, LLC Stinger RZ intake
American Racing Headers Headers 2” longtube headers and x-pipe
AlkyControl dual nozzle methanol injection system
Lingenfelter Performance Engineering high-pressure fuel pump
Fuel Injector Connection 30% DI injector set
DSX Tuning low-side auxiliary fuel system

“This particular combination was setup on fueling based on a power goal in the 900rwhp arena on pump E85, however our goals were blown out of the water once the car hit the dyno earlier this week. The final results landed at an extremely impressive 889rwhp/824rwtq on 93 pump gas, and 1,000rwhp/916rwtq on E85 at just 17psi on boost.“

Of course, Shizzy also posted his build which puts the little IL’ 2300 right there too.

Lots of choices.

[EDFHOBBIES]

Yes all choices, race gas 12 to 16 bucks a gallon.. meth what is that close 5 to 8 bucks a gallon? Hassel of sourcing a drum, bucket, and pouring in your trunk or over your fender. PRICELESS!

Kong is selling these things right and left and my shop has 2 inline for install so does the shop next door..

Gonna be a hard sale when u compare hood cut vs no cut.

The Magnuson 2650 fit just fine under the hood of the ZLE. I only had to slightly trim the water tray.

Except the results I posted were with 93 and e85 from pump. I suppose you could run race gas if you wanted to turn it up a bit more. I suspect that instead of spending money on the port fuel injection, it would make more sense to simply go with the 427 and hit 1300whp right? I suppose you can always do more.

Different strokes. I look forward to seeing a ported edlebrock crack the fast list or run at an event. It will be cool to see how they perform. As of now, we are seeing crazy fast times and getting faster out of the Maggie’s.

I wonder what the Procharger kids have up their sleeve. The F1 has long been the king.

[laynlo15]

Not anymore, gen6mike went 8.72@156 in Vegas a couple weeks ago and will probably break that this weekend in Cali where temps and Da will be more favorable. So hold on tight as we will find out today how low he can go with the 2650 Maggie Heartbreaker. That's at full weight of 3990 with driver. No stripped down 3500 lb Camaro. I think we'll see 8.50s

You are overlooking an important point here. The Magnuson is using a dual-nozzle methanol injection system as part of it's fuel supply. Meaning that it uses 2 fuel tanks instead of 1. The meth injection also provides a beneficial cooling effect, but the fact that it's being used for fuel supply is important to note. EDFHOBBIES clearly wants ZERO reliance on a methanol tank, he wants all of his fuel to come from the car's gas tank. This means using either high-dollar DI parts (the only solution available for a Magnuson customer that wants the single fuel source like he does), or, Edelbrock also makes it possible to add port injection. The port injection kit actually costs much less $$$$ than the DI parts that you'd need to support the 1041 uncorrected rwhp on E85 like he has made thus far. So it's pretty understandable why he chose that option. Obviously, if he was comfortable with relying on that 2nd fuel tank, he could have used the same fuel parts as your Magnuson example car did.

[radz28]

Thought there isn't much information except talk, Magnuson says port' can be added, too, just like (apparently) the Whipple. I don't know how they'd do it because it's only been stated it's possible at the time, but that might eventually become an option. I don't know that it will be as easy as it seems Edelbrock made it, but we'll have to wait and see.

Cordez had done 1000 RWHP a bit ago (I forgot about this). E and meth:

[laynlo15]

Several have already made over a thousand with 2650 Maggie. Tray on the Corvette forum made a 1044 on pump gas.
