Twin setup, advice?

[jjk]

I'm looking for advice on a twin setup I'm putting together. Currently I'm running a HTT Pro Street 66/71/16 with stainless housing and an S510 (worked over a little). The 66has an internal wg and obviously the 510 is not gated. I've should be seeing a bigfoot manifold this week. I'm planning on running two 50mm external wg's coming off the manifold (I realize this is probably overkill). I have a turbonetics mid frame hp-76 non-gated with I believe a 1.0 a/r. My question is given my two options for the small turbo which one would you run, the 76 or the 66?? I realize the difference in size and the spool up on the 76 will be considerably different than the 66, but this is for my 94 and will strictly be used on the track. Any input would be appreciated.. Thanks....

I would think the 66 would be a better choice. Even if its track only you still need you setup to spool as quik as you can.

a 66 should be plenty big on top, it wont spool as fast as a single 66 and should be well within the efficiency range with pre-compressed air running to it so it does not have to work nearly as hard to flow the same amount of air.
