Drivability blower vs turbos

I have a turbo 440 b-body, remote mount with an s475. With an S480 (80mm/1.32AR) you will be beyond the limits of any factory wedge block. An S480 will make a difference over the 75MM T6 S475 but the 1.32AR is really the limiting factor with big cubic inch. A 400 low deck (not 451) is really the best of both worlds in cubic inch and durability. You can mount a single S475 and make great power, enough to run mid-low nines on pump fuel in a reasonably light a-body with box stock aluminum heads and a mild camshaft (500-550 lift/[email protected]/112-115LSA). Also, with a 26" tire 2.76 gears work great, 28" 2.94's, 30" 3.23's (if running 727). Make sure you purchase a converter for a turbo application, I have one built by TSI (3,200-3,400 stall) and runs great with .528 solid cam from Mopar (great budget turbo cam). What I am trying to say is, yes some turbos may not be ideal but their is only 'so much' you can put to the ground, and 9 seconds in the quarter with granny gears should be enough for any street application. I would shoot for a safe 750-800HP, 9.0-9.5:1 CR @12psi (more with meth) as you will gain more power per/psi with higher compression. if your engine makes 500HP off boost, 15# is 1,000HP at the crank if everything goes right. Just keep that in mind, 8-12PSI is more than enough to make serious power with 400ci and the right turbo. The only thing I am going to add is it is much easier to build a SBM on a budget with a front mount turbo, as factory manifolds work. With a BBM their are no options for this, nor space (in a realistic manner), and custom headers must be built which really eats away at a budget. I didn't have the room, my spectre carb hat that you posted earlier has 1/4" clearance with my six pack hood... I was going to go EV or CSU but obviously they are 1/2" taller. Good luck, hope I helped a bit. It is easy to look at an all out race application and say 'oh, that looks easy enough'. Try stuffing a T6 housing that weighs 50# into your engine bay running full accessories in a street car along with a 5" DP. Torsion bars are what make it a nightmare. People who say it is easy normally have tube frame chassis and are running aftermarket suspension, non existent inner fenders, and tubular k-frames to push the shock towers outward. Along with this, most drag applications run the DP out the fender.. see how well that goes in traffic... A Small block with a T4 GT45 or similar turbo makes it worlds easier to front mount and will make 600hp without breaking a sweat.
