twin turbo 10.5 firebird

well i came up whit a batter setup.

Just a tip for you - if you're interested in accuracy, you're going to want to change it again. Your engine wouldn't run with it set up the way you have it. What you need is one big pipe from each exhaust manifold to a turbo (the inlet toward the rear of the car - the hot side). Then you'll have a big pipe from each outlet on the front end of the turbo (the cold side) to a "Y", to form one slightly bigger pipe. That pipe will go to your tank in the interior, and then another big pipe from the tank to your intake. The way you have it set up now you've got one turbo piped into the other and that would not work - the second turbo wouldn't last a minute with boost coming in the hot side.

Here's a pic that might help a bit.

the problem is you have one turbo blowing into the intake manifold and the other one heading to your ice box in the cabin,what you need to do is have both turbo's run into one pipe which then leads to your ice box and then plumb that into the manifold as per marks pic he put up for you,what your doing now only allows one turbo to be intercooled.

Hey Phil, glad the turbos arrived. Your putting in a good amount of work here so you may want to listen to these guys so the turbos are installed correctly. It would be a shame to put in this much work and create all of the piping only to route all of it incorrectly. Keep up the good work.

Well it looks like we typed our posts at the same time. May I recommend large diameter solder for the intercooler piping. You'll be able to make nice clean and realistic bends with it.

how is it confusing? so now its back to work on the icebox

i guess just because the hot side piping is laid out kinda funky, and the dual charge pipes aren't something you generally see. it is at least routed correctly which i cant say always happens with model car builders. just have to get the exhaust setup routed and it'll be complete.

what are the plans for the charge pipes?
