Alright, getting closer on the DT motor install and I need air for that Scheid 13mm pump and huge injectors.
Still haven't picked injectors yet, but the head will be ported.
I have a GT45r right now that I am thinking of either replacing with a 75mm billet wheeled unit and a couple of smaller ones for atmospheric, or running a couple of gt35's over the 45r.
Thoughts please!!!!!
Just remember to keep the turbos similar in sizes.
My 6.4 will be done in a month or so and it has the 66 with 2 62's that seems to be popular. Brian Spooner in his Dmax is running a GT45 with a couple GT40 w/upgrades(run 9's in the 1/4). Double overtime runs a HX82 with a pair of HX80's. These setups are proven. Stick with that formula and play from there.
You should be able to run that GT45r with a couple GT40's or GT42's. But if you plan on street driving a bunch I wouldn't suggest anything bigger then a 66 manifold charger with a pair of 62's or 64's. My 66/x62's has enough cfm to make 1200hp, plus it will spools fast.
I don't understand people doing the GT45/GT35's combo. Pretty pants did it on Jeremy's truck and I haven't seen it personally but it seems laggy for a triple set up(someone who has seen it can correct me if I'm mistaken). Personally I feel the GT45 is to big and the GT35's to small for each other.
If you really want more then 1200hp then go with a 372 and a pair of 366's or the equivalent. Bill form Bullseye told me I could have enough cfm to make 1400hp with a 66 and a pair of 66's instead of the 62's. Triples aren't like twins, small changes net larger gains.
66 on the manifold and 2 80mm under it. Should be plenty of air!
Like already mentioned, this would never work. Those 80's would never ever ever light lol.
