Vp twin set up question

Right now I'm running a super b special (64/71/14) and am wanting to look into a twin set up. Was thinking a 64/s475 but was told they were too close to work properly. So then I thought a 64/s480 but was told my vp will not fuel enough to make them spool.


So now here's the question... It might just be my redneck logics but i know a 62/s475 is an awesome set up, and there is 13mm between the two turbo sizes. So would a 64/s478 work out for me? Trying for something different. A buddy of mine is running something lIke a 66/83 and says it runs pretty well. I did think it was a little too laggy for my liking. What's everyone's opinion on the 64/78
 
I have a 64/74/14 and am going to eventually put an S480 under it. Its gunna have a benched 180 pump with 5x.018's fueling it though... I would think an 80 would be big but would still be okay for you. the 78 would be better though
 
So you guys think a 64/78 would spool alright for a daily driver? Im running 200hp cpp 7x0.012 injectors right now but will probably bump up to 250hp sticks when the time comes. Just dont want lag up the ass
 
Bwwwhahaha who in the hell told you a s475 wouldnt work well with a 64?? I ran a 64 over a s475 and it ran 12.0 with egts staying under1400* at WOT. I DD it as well and towed great. Lol the things i hear sometimes cracks me up!!!!

I'd get some of those 500hp stickzzzz and some 66/S488 twins, should make 800hp with a VP44 and spool faster than an HY35 on gravel.
 
You asked for advise....not advice. I'd advise you to size the turbochargers on more than soley the compressor wheel size.
 
Seems to be a few options...
