If we toss this on a Dynojet you'll have the torque numbers you're looking for. This Mustang dyno always seems to be low torque at low RPM compared to a Dynojet, but it repeats so well when tuning I hate to mess with it. My LT4 Z06 car is tuned to the knock limit across the RPM range on 91 octane.

We always end up at the track for validation anyway.
On our 2016 Camaro made 620 RWHP and ran 10.80@130.
With 730 RWHP our otherwise stock full weight 2016 Camaro on drag radials ran 9.93@140, so the power numbers correlate reasonable to track times.

That's what my goals are ..9.8 to 9.9

I thinking about doing the Maggie 2650 next year. My current mods are Lingenfelter overdrive 9.17 pulley CAI kooks 1 7/8 headers no cats. Would these ,kids work well with the Maggie and would I run out of fuel. My goal is to be about 750 rwhp. I’m currently at 664 any advice would be helpful first supercharged car so still learning. Thanks

Get a cam and you will be there now. With the Maggie you will easily run into the 800’s.

I was wrong. I apologize. We have some fantastic options. I encourage everyone to look at options outside of Magnuson as they dont work for me and I have terrible traction and driveability problems.

Chris I think you'll meet your goal with the 2650. Let me know if you need any other info.

Wow, its a shame they did the runners like that, just looking at the dog legs they added to the corner cylinders of the Edelbrock 2650 tells me it's going to have cylinder/cylinder distribution issues which will limit it's peak power potential - you really need all 8 cylinders working hard equally to make peak power.

The Maggie doesn't have any runners, just a bell-mouth entering each port.

I can only share this...

The 150HP number is from a 3rd party manufacturer who was looking to upgraded their current SC. All testing was performed at the same drive ratio even though their current screw SC was a larger displacement unit.

Baseline - The current engine equipped with a screw type SC.
Test 1 - One brand of TVS2650 which resulted in 50 hp more than their current screw SC at the same drive ratio.
Test 2 - Stage 2 Magnuson TVS2650R which resulted in 200 hp more than their current screw SC at the same drive ratio.

They decided to use the Maggie TVS2560R on their 7 second vehicles.

@toohighpsi - I’m just a few hours north of you and am happy to offer up my ZLE for testing...you know so I can give my unbiased opinion...that is only if I get to keep the 2650 after you’re done

Lol. Always a salesman. I’d say that too. I bought it over your design because of what could be done with it. I bet at 20 psi the air could care less on that 2.5” runner.

So you were talking about your race blower, not the Magnum, against a Whipple on a LS engine? I thought we were comparing two different blowers, the Magnum and Eforce 2650 on a LT engine in this thread. I could no doubt see your race blower beating any of these. It’s not the focus here though

All Magnum DIs are TVS2650Rs - we only offer them in a Stage 2 housing configuration - they have the exact same flow capability as the jackshaft units and have the added benefit of 10% more intercooler than the Jackshaft units.

Only benefit of the Jackshaft is the ability to overdrive the rear cogs, but with the large crank pulleys available for LT engines, reaching 25,000 blower speed and 1200+ RWHP is possible with the Magnum DI superchargers.

Lol. The straws keep getting harder and harder to grasp at haha

I honestly expected no more than 20 HP from the swap.

Really going to be interesting to see how the LT1 responds to this unit. We'll be running today, but will probably not get the dyno work finished until the weekend.

If that's a dyno jet I made the same if not more I was 700 on a mustang.. vs dynojet you know 400 hp range its not a big deal but 650s then ya it a bit more power but all dynos read diff.. but that's that's..

Also,

I don't like the tactics of the dyno sheets and mine is better than yours, and blah blah.. the sheets don't show rail pressure, Aux pump, headers, or intakes.. to many variables

I think your a great guy and you support the equipment you run as do I.. Plus your willing to answer questions like me.. I think your better composed than me and handle criticism better to..but i think I'm more compassionate about this stuff and more as a matter as fact guy that goes out and tests and gets answers vs believing a brochure and not seeing all the data..

Don't get me wrong the magnuson is awesome and the LS version was in a league of its own over the edelbrock 2300, the LT i don't know, the numbers on paper seem very similar, I think you have the numbers at the track because the LS Eforce was so bad and there just aren't many out there racing with them or making big power because of the LS issues of heat soak from longer runners that slowed the velocity However, they made a ton of torque.. For example the wife has my LT4 fuel parts and she's on 93 making 615 705.. she kicked the crap out my zl1 till i pulleyed it, Anyhow. just numbers..


I really don't like this adverting from the Magnuson site!

• New patent pending TVS2650 high flow supercharger

I guess the eforce is OLD


• Highest efficiency positive displacement supercharger available in the market delivers maximum performance with dramatically lower inlet air temperatures

There has been no head to head testing that is just going off old data

• Two massive air-to-water charge air coolers with 85%+ effectiveness

I guess that's a better approach then a huge 1 piece

• Low restriction inlet design

Are they saying the inlet on the eforce is more restrictive?

• OEM validated components ensures consistent and reliable performance

I don't know about you but oem blowers have constant Isolator bushing problems can't say that after market blowers have any problems really

• Same rotating components as TVS 2650 on GM LT5 engine

They all use the the same rotor pack

• Fits under the factory hood of Corvette and Camaro

Yes but no port option for this model

• No cutting of hood or cowl

yes but the port injection model does not

• Requires relocation of coils and /or new valvetrain covers

Great more time and hassles or money

• 30% increase in airflow over TVS2300 Heartbeat systems

That's applies to all 2650s

• 1,200 HP capable with appropriate engine upgrades

Not this unit unless port injection or hell of a lot of meth is used..

• Comes standard with 90mm inlet * 103mm available for purchase

Eforce came with 103mm


Please I'm not bashing you or them I just think the advertising or claims are lacking clarification..

like I said I like what you have to say your always supportive unlike me where i'm kinda harsh on my points..

thanks for listening..


Oh when you posted on my build you where very respectful ty.. but I didn't like you bragging that they had a unit that fits under the hood its not apples to apples if no port injection..

i use bragging loosely lol
