Just playing around with a few Magna manifolds, just to annoy all the US members. lol..

Here is the car one of these manifolds will be going on. In US Speek, it's a Sapporo, in Aussie speek, it's a Scorpion.

It currently has a draw through 1-3/4" Stromberg carb setup.

The 2 manifolds I'm tossing up to use are:

1. with  65mm (2.5") throttle body.
Posted Image

OR

2. This (haven't finished it yet) with a 70mm (2-3/4") throttle body.

Should be fun either way.

Also working on a quad 50mm (2") setup for my high comp Normally Aspirated engine.

Almost done..
Decided to go for a 75mm throttle body. Think it will work well.

To each their own & kidding aside, but Tim's right if you like physics.  A few questions:
1) Why use a bigger TB than the IC pipes you're running?  You won't flow any more at WOT or less (98% of run time)
2) You run 2.75 or 3" IC pipes?  Again - why?  How big is your turbo's compressor outlet?  None are that big. Won't flow any more
3) So why push MORE volumetric air with greater inside surface area of IC piping (more friction) by running pipes bigger than 2.5" (2.5" is basically = to 65mm)?
Again, back to #1.  

That reads more bluntly than I like, but it's to the point.  That's how I build boost at 1000rpm under load. Fit the pieces to match efficiently.  Also, a 65mm Crown Vic/Mustang TB is as cheap as any w/ the TPS you'll need often included or easy to find.

Keep IC pipes & TB the same (2.0 - 2.5" dep on turbo size & cfm) and you'll get fastest spool, throttle response, and easier fine tuning of smooth idle.
