LeadFred Posted January 7, 2014 Posted January 7, 2014 I would like to order a Ross Gibson engine in resin for a Pro Mod. Then i would like to build it with Turbo chargers. And TDR offers a great Turbo Ch... But you can choose from 3" or 3.5" or 4.5" in 1/25 scale.. What size should i use. Fred
MachinistMark Posted January 7, 2014 Posted January 7, 2014 Turbos are typically sized in milimeters just research the turbo setup you want to replicate, take whatever size in inches and convert it to mm (inches x 25.4) , and use the one closest.
MeatMan Posted January 11, 2014 Posted January 11, 2014 I'm doing a similar setup which shows using a "Pair of Precision Turbo 94mm Pro Mods" on a Mike Moran hemi. My converter program has that as 3.7 inches, so the 3.5" shouldn't be out of scale. Those are the ones I'm planning on going with.
ScaleDale Posted January 11, 2014 Posted January 11, 2014 Gibson engines tend to be oversized, so take that into consideration. Here are two BOSS 429 Fords, the one on the left is a Ross Gibson and the other is a Revell from the 70 BOSS Mustang kit. Dale
MeatMan Posted January 28, 2014 Posted January 28, 2014 Wow, didn't know that. I have the engine but haven't started the project yet. Now you have me thinking. Hmmm.
mnwildpunk Posted January 28, 2014 Posted January 28, 2014 I think don't quote me on this but aren't the Gibson engines 1/24th
