Magnuson TVS2300 and RWHP

I can't speak for the Procharger but I'm having trouble imagining getting 660 hp to the wheels on a TVS2300 with low boost (6-7lbs) and a mild cam. Methanol would get maybe another 30-40 hp. Certainly you would have to address new injectors and either a BAP or twin pumps.

For what its worth, my cam is 215/247 .629/.656 121CL

I hope you can prove me wrong...

This is what I'm using as a baseline.

My vehicle has a more aggressive CAM (Stage II) than the SPI shop vehicle, and I'm also having the dual pump system installed at the same time, so I'm making some assumptions and estimating about another 10-20rwhps.
Currently, my vehicle is making about 475rwhp. and this was after CAM install in Novermber, so really didn't get to tune and dyno with normal temperatures or get it just right.

This is why I'm in a dilema right now, was ready to order a Maggie and then saw this setup with such safe, low boost and subtle tune making these high numbers. And, knock sensors / AFR's are happy, which to me says this vehicle would be a total monster with 8-10psi. which from what I've read so far is still quite safe boost levels.

Seems to me the Maggie is great down low, but needs higher boost and still have to be carefull with knock sensors / AFR at those higher boost levels.

See where I'm going with this?

I do see where your going. Well, Oakville is right next door to you, I'd go down to SPI and see what they can do for you.

i installed a Maggie TVS-2300 on my bone stock LS3 with a K&N CAI and Stainless Works 3" cat-backs and dyno'd 490 torque and 513 HP on a Dynamax.

I'm very happy with the low end torque and it does feel like a big block as mentioned above. The Maggie makes a nice whine around 2 grand and mine will get even louder as soon as Magnuson can crank out the 1-1 cog drive I ordered last month. You can probably get 50 to 75 more HP easy with a blower cam and some long tube headers.

We have 3 cars with Vortech YSIs, My blower Cam, LT Headers, My tune, ADM fuelsystems, with Water/meth, and a 4th one in the build stages, Making 750 RWHP at 12 PSI.

If your thinking Centry blower you have to take a good hard look at the Vortech YSI.

I've got an LS3 with a stock bottom end, TVS2300 MagnaCharger, ADM Performance Stage 2 cam, KB Boost-a-Pump, 3.6 pulley and a Custom Tune by ADM Performance running 6.3 lbs. of Boost on 93 Octane pump gas and it put down 610rwhp & 540rwtq.

One more note, make sure that you get a custom tune before you get on it after the install. You don't want to take any chances considering you no longer will have a powertrain warranty.

the difference is great enough that even the variables of different cars would not effect the power differences you will see on the graphs.

Here is the graph Andy was referring to.

Blue is the car with the Magnacharger, red is the car with the ProCharger

my car is a manual

I would sugest taking a ride in each style of fi before you buy.Hendrix-Engineering has made over 800rwhp and over 840rwt with a 2300 with no meth or nos thats alot of power in a street car.Ive never had a guy ride in equally powered fi car and chose the centrifical over the maggie.If we can help you out before or after the purchase please give me a call..

[LS7 427]

By the look of the dyno comparison I'd say it speaks volumes for the Magnusun. At no point does the Procharger make more Hp or Tq.

As has been advertised the Maggie makes torque early and the Procharger comes on mid RPM range but at the end of the day it's the Maggie by a long shot.

I approve this thread...

Wow. Really intersting to finally see a head to head comparison overlaid like that. Great job guys.

Thanks for sharing. The setup and tune I'm looking at will make more high end power and low end torque, but for sure the roots will beat it on the torque lower end. Thinking I will make about 560-580rwtq and 640-660rwhp. at peak. I really like the look of the Maggie and the low end tq on such a heavy vehicle, but thinking the mods I've done already will get me into the higher RPM quickly enough to catch up especially when bolting on 6-8psi. boost.

This appears to be the norm on a well tuned vehicle @ 6psi. of boost with a maggie, without any meth. kit setup as a fuel supplement. Good thing for me is I think I'll be a par with the maggie folks, except for lower end torque, but at the higher end I'll have more HP.

Always, I went the route of canned tunes and quickly realized they are a waste of time, too bad I spend $600 on a Diablo Trinity to learn that very expensive lesson.

Yeah. That would be great if (2) 2010 Camaro's sitting in the shop, one with Maggie one with ProCharger and the owners let me go on a very high speed test drive.

Is there realy that much of a difference? I would think the centri would be a fast steady accelleration, while the maggie would be very quick at first (tires spin) but then once hooked, wouldn't make much of a difference.

Well if you look at the dyno sheet posted above, at no point is the procharger making more power than the Magnuson, even on the high end.
