Hey guys, So I have been talking with Paul and another compound guy about running twin scroll into the big first and then into the small. I plan on controlling with twin 38s on the T.S and a single 44 for the small.
I bought a HX52 billet 7 blade in a T5 twin scroll and a H1C with plans for a BEP T3 .70ar exhaust housing. I will still route the compressor with the big feeding the small. I know Paul had back pressure issues with his set up but was it because there wasn't enough gate, exhaust size, turbine size, ect ect....
I know that Pauls 60-1 still had the same spool times by itself as when it was in the compound set up. The exhaust/heat energy argument is hard to believe with that experiment. With that being said regardless of where the turbos are they should spool the same. The biggest thing is utilizing the twin scroll and the possibility of me not having the sell my 2 38mms and buying a 44mm and a 60mm for gating.
I guess it really comes down to where the turbos are going to be located in the engine compartment and ease of fabrication/install/removal. I am all for making things simple( ya right) as I can for working on my car.
Thanks for the input.
