Anyone know the performance boost in just adding a MP plenum ?

I plan to upgrade the intake side of my car, but just hear that remove the plenum is a pain in the arse.
 
They claim 23 RWHP if you go with the 85mm TB also.

Yes, you have to take off tha supercharger to get the plenum off.
 
I noticed a difference with just the MP plenum with a 75 mm TB and a 76 mm mass air...now if I had a 85 mm TB....Id need like a 90mm Mass air or Id be restricting that 85mm TB..I dont even hav ea freakin 85mm TB on my 750 rwhp turbo v8!
 
Let me get this straight, you can bolt on that big ass Magnum Powers inlet plenum to a standard charger without doing the Magna Port II thing to the M90??
 
The MP inlet plenun will bolt to a 94-95 supercharger with no mods, but not the early 89-93 style. Of course, I'm sure it does more with bigger TB/MAF and supercharger enhancements.

My plenum is just hooked up to an old "S" model charger.
 
Just so ol' DrewsSC doesn't think he has gone crazy, I inadvertently made that previous post while logged in with his ID! I was helping with some user issues and forget to logout of his account!

Sorry about that!
 
Early Blower + MP Intake

Didn't I read somewhere that MP is making in intake plenum to fit the early blowers? I don't think I dreamed it!
