Honest 500 Rwhp

[as10trk]

Is it possible to get an Honest 500 RWHP on an SSR with the following parameters?

Supercharged in some form
2006 Year model
Auto Trans
No cam or base engine modifications
Emissions legal in State of TX

If you look on Corvette Forum on the Forced Induction thread it would appear that almost everyone gets 500 - 550 Rwhp with superchargers and no other major modifications. The have the same LS2 motor that is in the SSR as far as I know.

I am open to basically any type of supercharger type kit whether it be Magnuson, Paxton Novi, Vortech, etc.

The only kit I have researched so far is Magnuson and they appear to fall short. As near as I can tell from their literature, the intercooled Maggie 112 kit only adds approximately 100 Rwhp over the stock Rwhp of 320 or so.

Any help you guys/gals can offer will be appreciated. Thanks in advance.

The biggest thing you need to do to get the 500 RWHP number is the Throttle Body Change, 2.8 Pulley Boys Pulley, Dayco PolyCog Belt and a Custom Tune with a free flowing exhaust.

Feel free to give me a call if you want to go into more detail on this.

Yes it's possible. I've gotten 518 rear wheel horsepower and 515 foot pounds of torque on my 05 SSR with a 6 speed. The drive train loss between the 6 speed and the auto are about the same. Here's what I've done to get to than number

Headers
3 inch exhaust
running a 2.8 inch pully overdriving the Magnuson supercharger.
corvette throttle body
Air Hog air filter, cut away the front cover on the air filter
removed the MAF screen
custom tune.
Ron Davis racing radiator
Aux fan by Simple Engineering
Auz fan on the suppercharger intercooler by Simple Engineering
Custom intercooler mounting bracket by Simple Engineering

The 518 horsepower was achieved while running 100 octane racing fuel.
I've been running Premium daily and have had no ill effects, Trucks been running GREAT.

I had my '06 six speed re-tuned two weeks ago at AZ TPI after the 4.56's broke in.

With:

Magnacharger w/2.9 pulley
C6 throttle body
K & N Airbox
Dayco belt
Air Mobile polished aluminum radiator w/ custom Cobra cooling fan
Stainless Works headers
3" exhaust w/ Magnaflow hi-flow cats and Flowmaster 50's
HP tune
4.56's

all they could squeeze out of it was 498.2 RWHP

That was with Phoenix pump 91 octane premium.

I know you asked about automatics, but hey, if we can do it with six speeds, you can too......

[Doug Allen]

I got most of the parts from Joe.....

Is it possible to get an Honest 500 RWHP or more and 500 ft torque on a 5.3 if it is set up right and get 21 mpg at 70mph with no cam, Stock block, I don't see any short comings of the Maggie 112, What more could you want

[2005SSR6Speed]

The best part about the 112 is all the low end torque off idle.

MagnaCharger makes 3 Rotor Groups right now:

MP112 - Great Low End Torque - Approximately 550

MP112HH - Great Low End Torque Like Regular 112 - Approximately 600 HP

MP122HH - Not as Much Low End as 112 but Great High End HP - Approxiamtely 750 HP

The HH stands for High Helix. The 112 has a 60 degree helix twist to the rotor group. The 112HH and 122HH have 10 degrees more helix or twist to 70 degrees.

[2005SSR6Speed]

We have found that the 6 Speed with the 14 Bolt Axle will dyno at the same as an Auto with 10 Bolt Axle.

[CQQL_SSR]

If you use the MP112HH with the automatic and the 10 bolt rear will it hold up or should it be changed to the 14 bolt rear from the 6 speed?

is this where the extra whine comes from

[2005SSR6Speed]

The stock 10 bolt has been surprising me with the additional power. I myself would upgrade to the TrailBlazer 14 Bolt with the 4.10 gears already in it and you wont hurt it.

Boy Joe that Not as much low end sure sounds good

[2005SSR6Speed]

The problem with the 122 is that it is made for real high boost levels and unless the engine is built for you wont see any gains.

Joe-

Sounds like the MP112HH might be the way to go.

That being said I am really interested in keeping my SSR fairly quiet and am concerned about going to headers and high flow exhaust systems. I don't want my vehicle to be any noiser than the stock exhaust if at all possible, but would like the HONEST 500 RWHP without all the exhaust noise. I sort of like the sound of the older muscle car mufflers we used to call "Turbo mufflers" where you can really hear more engine sound than exhaust sound.

What do you think?

[2005SSR6Speed]

The sound of a free flowing exhaust is probably the easiest thing to accomplish. I would purchase the Kooks 1 7/8" Primary Headers and Cat Y-Pipe and have a shop custom make everything else so it is just the way you want it.

Joe As you know, I have the 2.9, and the new T body. I just redid the exhaust by removing the Y and am running a Magnaflow 4 in 4 out (sounds awsome and there is about 0 muffler backpressure. So now I am thinking about the 2.8 pulley. I know, I know I'm . Would that be a noticible change IYO and seeing as we can only get 91 octane, do you think that a trip down to Carlsbad fo an updated tune is wise, or do you think a dyno tune is a good idea at this point. What your last tune did for my truck last month iws awsome by the way.

[2005SSR6Speed]

I would say the dyno tune is best next. I can handle the driveability tune but you need a dyno for all the WOT tuning.

[FlashBack]

Thanks. Didn't you mention someone before that you reccomend.

[2005SSR6Speed]

I will have to do some checking.

I was actually thinking about asking Joe the same thing - I have the 2.9 pulley. Would it squeeze a few more horses out of it with a 2.8 pulley (with 91 octane premium here in Phoenix)?

[2005SSR6Speed]

What you need to do is get a boost reading. Depending on the exhaust and throttle body you may be able to run the 2.8 without a problem. The other down side to a 2.8 is the heat in Arizona during summer.
