For the 600 whp target you would need LT4 fueling at a minimum with the P1X. My original setup was going to be P1X, LT4 fueling and headers.

Sounds good. I prefer the LT4 / 1700 blower.
I like the idea of having a stock looking engine bay and prefer a PD system over a Centri (I.E. Centri P1SC /X). one
In order to lower the boost, I would have to mount a smaller SC ring on an ATI Super-Damper pulley, instead of using the stock LT4 pulley, which brings about a stock boost level of ~ 9.5- peak 11 PSI on the LT1 motor .

With a smaller ring, I could adjust it to a 7.5-8 PSI boost.

Since E85 is difficult for some of us to attain, pump 93 has limited potential, and straight ~110 race fuel is way too expensive, what are the pro's and con's of adding meth to pump 93 ? Could 650 whp be safely achieved with 8-9 psi of boost on pump 93 with straight meth injection ? From my understanding the systems are pretty safe these days, and work very well with forced induction.

Plenty of guys using it just for cooling with a lot of success. I still don't like how unreliable the pumps are with these systems though. For now I'll keep running Boostane for 98 octane at an extra $4 every fill up.

You haven't had any ill effects from running Boostane ? I've read it can cause carbon buildup on the pistons, and leaves the spark plugs coated with an orange tinge ?

Does the stock tune on magnuson TVS2650R Magnum have a good amount of pops and crackles running 93 and no E85 kit?

If you run a ProCharger with the factory air box and flex fuel, is an intercooler even necessary ? With a proper LT4 fueling upgrade, is this something that could attain ~650 whp ?

I would say its best to have an intercooler. I run this exact setup and without it I'm not sure I would get the same results I'm seeing now. Keeping the temps down is the name of the game and without it you may not see that 650whp.

Absolutely necessary!

Please forgive my ignorance on this subject guys, I'm just trying to figure out my best option for a FI system. I was pretty well set on a ProCharger system, but now I'm also considering a Maggie. This is for a non daily, sunny day, fair weather fun car. It's never going to see snow or rain, or a track or drag strip. Street/highway fun is where it will live its life, 3k-4k miles a year.

I'm all over the place with what direction I might go. My original thought was a 94 tune with a ProCharger, I've also considered a Maggie, meth/water injection, and E only as a last resort. I have no problem with E, other than the hassle it would be to attain it in my area. Some folks might not like it, but I like the whistle of a ProCharger, and the sound of a good blow-off valve. On the other hand, this car will continue to look and sound stock, and a Maggie would keep with a overall sleeper theme.


I understand that a Centri and PD build boost differently, and now feel I would prefer to have more power down low, but not to the point where it would be unusable on sticky 20" 315 street tires. I don't care so much about a dig, or top end speeds, I would like something that gets from say 30 to 130 in a hurry, in theory of course. lol.


I have a stock M6 car, and it just feels weak down low under normal driving conditions, I guess the A10 would feel better through the entire rpm range.


I was thinking if you used the factory air box with a ProCharger that you might not need the intercooler, but I guess even if you're bringing fresh air into the turbine, it gets heated up there, and would be hot going into the engine intake. The intercooler would cool it down between the outlet of the ProCharger and the engine intake. Is it not necessary to have a intercooler for a PD set-up ?


Currently I'm thinking of going with a Maggie with flex fuel, LT4 fueling, and catch can, hoping for a safe and long lasting ~650 whp with stock clutch and exhaust.

The Stock manifolds and cats would be the limiter here, not so much to making the power but engine longevity due to head retention.

Long Tube headers with High flow cats are strongly recommended for this power level.

Same power can be made with lower boost and cooler EGT.

This power level would only be (SAFELY) achievable on either 98 octane or Flex fuel of at least 40% E content.

600 RWHP is pushing the limits on pump gasoline E-10

A maggie 2650 pullied for 8-9psi would make power similar to a Procharger running low boost. That unit is designed for 14+ psi. A LT4 supercharger pullied for 8-9psi would result in a faster car. Sizing the blower properly for boost level is a thing just like you would a turbo. 9 psi is right in the meat of the LT4's efficiency range and way below the 2650. So the 2650 is going to build boost just like a centri. Probably will be around 4 psi on the stab of the throttle and build to 8-9psi by redline.

I honestly do not know why the 2300 was discontinued because the 2650 is way more unit than most need. I have seen ZL1 guys install a 2650 with canned tune and barely run any faster in the 1/4 mile vs stock blower. LT4 blower makes a lot more sense for what you are trying to do. The 2650 is a awesome unit don't get me wrong but unless you plan on pushing north of 850whp there are lower cost options available.

They all going to say the same thing.

Agreed, I wish the 2300 was still an option.

We should note, the 2650 will be easier on the high compression LT1 than a 1740 because it hits hard well below peak torque.

Boost pressure at Peak Torque is what we have to think about when boosting high compression engines.

For the factory setup a P1X would be the way to go if you do go procharger. When I got my setup my first thought was to go maggie but it was during covid and the turn around time was 6 months. Got the PC setup in 3 weeks and haven't looked back. I basically use my car like you intend to use your as a weekend warrior. The way the boost builds is awesome feeling to me. I can give it a little without going all out keeps me out of trouble.

Took my wife for a ride yesterday and did a mini pull went from 40-120 in no time she yelled at me so I let out of it. Will def give you that rush of adrenaline when the boost kicks in.
