I'm looking into upgrading my manifold (since logs flow like crap) and I was looking into T3 divided (twinscroll) manifolds. I'm quite sure the Pfab can be had with a T3 flange, but what about the Full Blown and AFI sidewinders, are they available with a T3 flange or only T4?

Any others that I'm missing?

As far as I know, there are not any bottom mount divided manifolds are there? I really like the Ptuning manifold, just wish it was divided.

 

honestly i dont think a divided set up is nessesary on a t3

 

I still can't justify the twin scroll thing.

What are you going to be using the car for?

I'm still not totally sold on it either (especially considering the price of most of the divided manifolds). I just thought it was something to look into.

The car is an all around car. It sees a pretty even mix of drag racing, autocross, daily driving, and (soon to be) road racing. My main desire was a super fast spool, and the log delivers that, but I want a little more power (shooting for ~450whp reliably) without losing the quick spool (and possibly even improving it). I thought I read somewhere that the one of the twinscroll manis spooled a GT35R at 3700 RPMs. If thats true wouldn't that make for an even faster spool on my GT3076R? If so, that would be truly awesome. Even if it is possible I'm not sure the money will justify it though if a similar ELT manifold will be almost as good... just looking at all the options currently.

Might end up just having something custom made since a buddy of mine does amazing TIG welding, has good fab skills, and would probably do it for half the cost of these other manifolds.

 

AFI manifolds are either T3 or T4
