MTI Racing's LS1 F-body Magnacharger system now available for mail-order

I agree that the maggie supercharger is not designed for peak hp numbers and 600rw is probably the most you will see. The great thing about this system is power under the curve. Most driving occurs between 3-4000 rpms and this is where the maggie shines. Peak or high rpm horsepower looks great on a dynograph, but on the street low end torque is what matters.
My only concern is if the charger is maxed out, does that generate more heat than a charger that wasn't? Does that make sense?
MTI, how much power is the car that has 10.5lbs making? How many lbs are you running on the car that has the dyno graph. I thought I read it somewhere but I can't seem to find it.

People say it maxes out around 580-600 RWHP. That's freakin alot. I don't see being able to use much more than that on the street IMO.

The dynograph that we posted is of our stock 2001 Camaro SS which is running on 7.5lbs of boost. The green camaro that we use as a track car makes approximately 560rwhp on 10.5lbs of boost but also has other mods. To show the values of just the added boost, I am doing some research on some of our previous installs which we did some dyno testing at different boost levels and I will post the numbers shortly.

We had a local camaro owner come by the shop recently who had the above mentioned competitor's Maggie kit. Here's a couple of pics of his car vs. one of our maggie systems. You decide if they are they are the same.

Thanks for the replies. You do have a nice looking kit.
What about the efficency/speed of the charger. What type of intake temps where you guys getting.
That would be great to see some other combo's to see the different levels of power output.

I looked at the dyno graph again and the amount of torque at 2500 rpm is just sick.
The power seems to drop off around 6-6.5grand? Is that where the stock cam stops making power or is the blower? Would a different cam change that?
The fit and finish of the kit looks fantastic. I have been searching the boards for the last two hours reading about Maggy's. There seems to be a lot of negative info on them but I don't know if it's true or not.
It's like when I bought a big TV. I had to sort through all the BS from people that really had no idea what they were talking about which was better LCD/plasma. I feel this situation is similar.
Would a reverse split cam, like the TR230 cam help build more boost because the intake is staying open longer or does it not work that way?
Would running E85 help with the IAT's?
I am not meaning to
I will limit my questions or PM MTI. I am just trying to learn.
I have ditched the APS TT idea and am looking at other FI options. Each has its drawbacks.

The power dropoff at higher rpm's is basicly because the stock heads and cam can't keep up with the supercharger. We noticed this as well in our green 1994 LS1 powered camaro track car. Horsepower began to tail off near 5500 rpms with the factory top end, so we did some work on the heads and installed a new cam which produced 50 peak rwhp. Instead of horsepower beginning to drop at 6000 rpms, with the upgraded heads and new cam it continued to gain thru 7000 rpms.

So I know the meth injection is bad for the cooler (also heard it eats up the blades), but has anyone run just straight water to help cool the temps?
Great looking kit

Question here, how do you guys route the throttle cable? On your system its on the driver side vs. the passenger side on the other system. I see the cable for you system, just trying to understand it better. Very nice system BTW

IAT's vary from car to car, driving circumstances, amount of load, etc. The maggie does produce higher IAT's but in no way are they dangerously high. Tuning will accomadate for these temps on each individual basis. We've had great success with our MP112 system even on extended runs on the road course and haven't noticed any siginfigant power loss due to high IAT's.
The throttle cable on the F-body begins on the drivers side of the engine bay and crosses over the intake manifold to the passenger side to mate to the throttle body. Our system simply re-routes the flexible throttle cable eliminating it from ever crossing over to the passenger side.

We just picked my "98" F body up from MTI to day. The kit had been installed in SC (where I live) and hauled to MTI for tune. The "98" was a one year wonder as far as the EFI set up is concerned & quick mods to the computer (which MTI did for us) would not let it do any more than just fire up. It's rained every day in Atlanta so a real test drive befor taking it home would have probably ended in disaster so I really dont know what I have till We get it back home and strapped down on the dino.
Maybe I can shed some light on a couple of the above post. 1) The body goes up when the shims are installed. Absolutly nothing changes as to the front end geometry. You will need to have the front end aligned after having the front subframe dropped down and put back up. 2) There are no shims for the rear tranny cross member or the front sway bar where it mounts to the body included in the kit. They should be included. 3) A lot has been said about having to cut a piece out of the body just about where the right WW is to clear the back of the blower but nothing is said about cutting the underneath side of the hood where it crosses the front of the blower at the TB. This actually is not as bad as it sounds and mine came out looking almost like factory original. 4) The blower extends pretty far forward which in my case doesn't leave enough room to get the MAS unit back in front of the TB and still get hooked back up to the SLP box lid. This resulted in having to go to a Speed Density setup which turned out to be a major hurdle for MTI to over come with the one year only ECM. I do plan to come up with a way to get back to a MAS setup as soon as possible. I must say the guys at MTI that I delt with are great. More later

NightMoves, Your camaro is a big fat torque monster. It drives fantastic! It starts going sideways as soon as you give it your pinky toe on the gas. Instant throttle response. Keep us posted on your quarter-mile times.
