Throttle Body Mounting Plate

Hey.

Spent the better part of yesterday fabricating a new mounting plate for the E-Throttle Body and whizzing off the original plate from the intake manifold. 10mm ali plate, , measuring, scribing, grinding, linishing, dremmelling (is that a word?), sanding, drinking, 70mm hole, drilled and tapped M8x1.0 bolt holes. The strangest thing about the process, was that I got it right first time with no stressed-gibbon-like tossing around of aborted first or second attempts. What went wrong? ;-) I did screw up the original M6 mounting holes (long story), so was forced to take them out to M8 and nervously run an 8mm drill through the M6 holes in the throttle body. Eeeeek. Chewing of finger nails and furrowed brow.

A bit of work to change over from the OEM TB, but this had to happen, despite the move to DBW, as the OEM TB was too small for the projected HP. 60mm plays 70mm i/d. Doesn't sound like much, but gives approx 30% bigger cross section.

Tuner Chaps reckon 70mm is good for 600hp. Good enough for me. But then the intercooler is 2.5" (63mm), so is this a restriction? Spearco rate this IC at 750hp, so obviously not. Stop over thinking things, Gaz.
