Similar camshaft, he has a SoCal 6480af.
I'm in the middle of a very similar build except running an S485/96 1.32 over a 68 mm stg 2r (for now anyways, contemplating an S366 or 467 instead) Same injectors, pump and camshaft though. I was running the 1078 from Evan at Inglewood with just the 68mm and it was suggested to me that it would still be a good convertor for this setup. It is very similar to the R but is Evans design from Suncoast. Im not sure on the exact differences ,maybe someone who's had both can chime in? Once I have everything together i will try it out and if it's too tight i will be going with the Goerend K or J. Best of luck with your build!
R and 1078 are very very very comparable.
I know they both use the heavy duty pump from the Kodiaks and stall speed is more or less the same. What are the other similarities? Anything against the 1078? read that it was built primarily for Vgts so maybe not the best choice for OP since he's running a Borg in the valley? I've only run this converter and an E before so I'm not too familiar with others. I'd love to get some information though.
I'm just not a SunCoast fan. They don't seem to take the abuse that Goerend does lately. The SunCoast converters also seem more prone to ballooning at higher pressures in some big HP builds. They're almost identical converters. The R flashes a touch higher before it really starts to couple.
I have zero complaints in multiple trucks with an R and a S300, it works very well IMO. BF is another great choice and I personally prefer it to the K. I've ran an R and K in a 364.5/480 truck, they were very similar in performance in that specific vehicle. It seems that the K needs a quick reacting charger (or chargers) to maximize it's potential or at least that's what my experience with them has been.
Please don't infiltrate the forum with this term hahaha. There's no vanes to fix in an S400 or GT4094R. GT4094R won't really make much difference compared to your 68R as they flow the same. 68R is based on a GT4094VA
Thanks. My thoughts were the exhaust housing on a vgt can cause higher drive pressure because of the vanes. So a fixed geometry (is that better?) turbo should in theory help decrease that. Not really looking for more airflow as you said, it's capable of 1000 as is. Maybe I'm off base. That's why I'm asking questions.
For 1000whp I would, personally, leave the air alone. It's a proven 1000whp setup that drives very very well.Yes , sounds stupid now that I think about it!
