Stock L99 A6 Supercharger options, opinions, & experiences

[Darth_Emma]

Thanks for the comments and the pictures. It looks like my CAI intake will work fine with the TVS2300. It also looks like the Maggie might add about 120 rwhp? My car currently is making at 362 rwhp (L99 with intake, headers, exhaust, and tune).

That's about right. Maybe 10-25 more hp, depending on the tune and octane.

And which headers are being used. LT's are worth approx 20-25 more than shorties... My numbers are on shorties, no muffs, CAI and 91 octane

The 362 rwhp is with LT headers, intake, exhaust, and a tune. I'm hoping a Maggie will get my close to 500 rwhp.

Don't waste your $$ on the warranty. As been said before, what they pay won't cover your losses and in your case, you've voided it already with your LT's.

I think if your looking to get close to the 500 number, make sure to use the 3.6 pulley. I also did a L99/LS3 conversion plus a GT-11 cam with the 3.6 and pulled 553rwhp running 6.5psi.

And unless you get the scroll size matched perfectly to the engine's capabilities you are gonna have lag (too big) or just not make the numbers you want (too small). And it really is irrelevant as the bottom end of our engine's is not gonna like more than 8-10psi, so I would rather have the instant hit from the SC.

The maggie is 100% self contained. It really is a very nice package.

Let me start by saying I am a huge fan of Magnuson and we work hand and hand on projects. With that said please allow me to address a few of your statements:

That is subjective – As an example, when installing a turbo, you don’t spend extra money on pulley changes, you don’t need to drill into or install the crank pulley, you do not need to modify the heater hoses and plumbing, you don’t need to plumb hose to and from the heat exchanger (installing the heat exchanger for the Maggie is the same time it takes to install the Intercooler for a turbo.

Nope. No piping or drilling of oil pan. Oil drains back into the valve cover. And most turbos these days do not require water cooling.

I agree there is more tubing with the turbo than with a Maggie system but no more than a Paxton, Vortech or Procharger set up and in exchange the discharge temps are way lower on the turbo then the Maggie. Air to air intercooling has a lower discharge temp then a Maggie at boost and cruise

Nope. The Maggie sits smack in the center of the engine and compressing air makes heat regardless of the device that compresses it. If you have a top mount turbo I agree the Maggie is most likely cooler but twin turbo like the Hellion and TTi/GMS kit will have lower under hood temps than a Maggie for 2 reasons; 1. They are down stream of the stock exhaust manifolds and 2. They is nothing in the engine compartment to make the temp goes up – Naturally at boost the turbos create heat but the air from the turbo is cooled by the huge tubing and heat from the housings is dissipated by the air rush across them at cruise

It is pretty tough to run too small of a turbo when there are twins. Even 2 pewny turbos like 50mm each would make 800hp which is a ton of power – the Hellion turbos are 58mm and the Granatelli turbos are 62mm I can tell you there is no lag on the Granatelli system and looking at the Hellion numbers they don’t lag either. Admittedly the Maggie will make more torque below 2500 rpm

Again I agree the Maggie is nice and as easy to install as any other system. But if you talk about stress on the engine the turbos create les stress because they don’t drive and create crank shaft load. The number speak for themselves – if your goal is 600 rear wheel (100 more than a ZR1) then you can get there for less money with w twin turbo set up and have less stress on the motor because it will take less boost

Nope. No piping or drilling of oil pan. Oil drains back into the valve cover. And most turbos these days do not require water cooling. Where are you obtaining the oil to lubricate the turbo(s) then? You have to tap in somewhere...and tap in again to route to the valve cover(s)

Air to air intercooling has a lower discharge temp then a Maggie at boost and cruisebut as with most front mount IC that are air-to-air and need to be very thick in comparison, car cooling suffers or has to be modified in some way to handle the extra heat shed into the rad by the IC

Not arguing here, just pointing out some stuff that I have seen in the past and can make a difference in some folks minds and some kits don't address...

[Granatelli]

Oil comes from sending unit - just a simple T goes in line and oil goes back into the valve cover through the oil fill cap - no drill or tap

No mods to install intercooler either

i have a L99 car with Cold Air Inductions CAI and i want to do a whipple 2.9 with LG Motorsports super pro headers and LG's 3" exhaust has anyone done this or are we still waiting I have a year to go before i can pull the trigger just was wondering if it has been done yet

Whipple didn't release their blower yet.

I'm leaning toward the KB after reading this and other threads, nothing against Maggie it seems the safe way to go.
Question for you guys i also have the CAI intake installed will it work with KB?
If not i have no problem selling it and going with the KB mammoth, the only thing i am wondering is the filter looks pretty low, will it not take on water when driving in rain.

If you saw the KB setup there is no way you're aftermarket intake that you have on there now will fit a KB. So, you would have to sell it, or keep it, give it away, or whatever else you would like to do with it.

Where are the best places/retailers to order a maggie, kenny belly, procharger, or vortec from ? Are the kits any different depending on who you order it from?
