S480 vs S475
S480 vs S475 I am at a new crossroads regarding a pending forged 370 build. I have been scouring the ads for a decent turbo and always end up back at the the ForcedInductions site. Now here is my question if the S400SX-75 ETT* is good for 1050hp on a 1.10/83mm for $700, why would I pick the S400SX-80 ETT good for 1055 on 1.10/83mm for $900 more? The goal is to run 9's in an old A-body with a 4l80e and 3.08 gears. I just want to buy one turbo, one time, have fun on pump gas and meth and call it a day. Don't care to go Chinese for this particular build if I can get a name brand beast for $700.

Neither of those will support over 1000whp on 370". You'll need a 96/t6 hotside on a borg s400 chassis to get there. Those are likely maximum hp numbers based on use with smaller displacement engines. What is your power goal? We can work backwards from there to see where you need to be.

I do not have a specific power goal friend. I do however have a time goal and fuel requirement. High 9's through a 4l80e, 3000 Circle D stall with 3.08 gears, and 295" drag ET's. 93 oct with meth injection (read washer fluid) Car weighs in at 3400lbs.
I know these turbos won't support 1000whp, but can they support 9

If you can nail down a power goal and let us spec a turbo, we can stand behind our performance guarantee. If the turbo doesn't make the power we say it will, we'll make it right.

There are too many variables for me to spec turbos based on ET goals. As a manufacturer, we have no control over the countless other aspects of a car that go into an ET. That's a good way to get myself in trouble, lol.

blah, blah, blah, was all I got. Seems people did not think the hp number was as relevant as the desired ET's. That might have been on YellowBullet; I am to scarred to remember clearly...lol. Seriously though, I would like 700whp consistently with room to grown should I stumble across a stroker crank. Once I hit the 9's they will boot me off the track in Bradenton and I will still have a true streetable 9 second car with a/c.I am definitely not keeping it T4. The T4 is on the Lemans along with the Chinese GT5. The Skylark or Chevelle is getting the T6 S4XX

Can anyone explain why the T4, costs MORE than a T6? That seems backwards to me. And who has the T6 475 for $640 shipped? Thats cheaper than I have seen.
Maybe this will help put you into perspective. My car was about 3410RW when I ran the time in my sig, and I did that on a cast 73mm T6 Garrett 0.96 A/R on 13psi. My turbo does not have a 96mm turbine wheel either. So basically, with a 96mm S475 1.32 or 1.10 A/R you could in theory go faster at the same boost level.
But like cptjck said, you can't really promise someone an ET. You would need to be able to launch as well as I do, etc. I have been blessed to have no traction problems with my car, but I can tell you from what I see at the track, I am a rare breed. Many cars that are not well setup just spinning like crazy at the track.

Figure this out the billet 76 makes about the same power as the cast 80 and then look at the cost. Is spool up different between the two? I would assume the 96mm turbine would spool the same? Am I wrong? I realize the billet 76 is a class turbo and that has a lot to do with the price and the power it makes. But for the average guy that doesn't give a damn, what's the difference?

If we sell a borg s475 96 t6, we just put a label on a borg box. If someone buys a borg s475 87 t4, we have to assemble it from various other units, balance, rebox it, etc. That's why it costs more.
