VMax Manifold Spacer...12hp for $269

[rabidbandit]

Well...I don't think this product has been given our full attention. Looks like they are on the right track. Plenum volume increase would probably help us out. If it works for the LS1 guys going from the stock man. to the LS6 manifold...then why wouldn't it help our cause. The only thing that they gain is effective plenum area, ports and TB are the same size and location...but they tack on decent hp #'s. This isn't guesswork...I build and tune 3 TA's two 98's and a 2000 WS6 for some friends of mine who don't have the time nor the patience to learn themselves and I'm pretty amazed of the potential of these engines. With ours...it seems that the main problem is the TB location as most of you guys already know, slams the incoming air right into the lower intake floor...crappy design from GM. The remedy would be to either install an edelbrock man. with custom fuel rails and injectors with a 90 elbow and TB for mucho dinero, get mercruiser's intake setup, design a forward facing upper the doesn't get in the way of the waterneck and other accessories, or just increase the "Floor" distance to allow the air to travel to their respective ports more efficiently with less turbulence. Just wanted to get your opinions on this product...looks pretty straight forward. I want every last drop of power from this engine and still have road manners. Sure...I could swap a V8 in...but what would be the fun in that:D

I'm going to buy one just for kicks...I think I'll have to get a cowl hood as well to allow for the K&N setup to clear...also to vent some engine bay heat. I'll get pics and Dyno results from all my mods after I get the Edel. headers. I'll shoot up to TTP Performance north of me to get some Hp and Torq #'s when all is said and done:)

That should be one of the first places as its one of the biggest places hp is lost

I looked up a thread on the fullsize truck forums and the spacer made a pretty substantial gain off the line and from 1500 to redline?! Enough to tell for the A** dyno:) That was a 5.7 though.
