Here is a picture of the setup
I think the cap is a 16lb. So the catch can gets the tube that is out of the top of the cap? Right now it's just draining to the ground. I've seen the catch setups used on mustangs that are a plastic bladder - that could fit in there nicely. How much capacity should I get?
Also, where is a source of a high-flow thermo? I've been to all of the usual places and all they have are the cheapo ones.
And while we're at it, it has/had a 160*F. Is 180*F better? (This is a Roush 427IR, basically a 351W).
Thanks!
