Good god. I hope this is just a play truck. That's a lot of fuel and air! I wouldn't mind playing with that setup for a weekend.

My guess is you won't light those until you about 2000-2100 rpm. Probably won't hit peak tq until 2400. I ran a single 72 for a while and that is about how it acted. I am guessing this setup will be close. Get turbo blankets for each exhaust housing and double wrap your midpipe. Should help spool. Ceramic coating the housings and midpipe if you can will also help spool

I don't have personal experience but I bet it wouldn't be bad considering you have a 2500 stall converter.

You are running the 467 right now? What size housing and turbine do you have? How does it act now as a single?

I've played around with the S465 and S467 as singles on my buddy's common rail. I'd recommend the S465 as your secondary for one reason and one reason only. The power below 5 psi.

The S467 flows like a bandit on a 6.7 above 1800 rpm, but it's lazy until that point and hits like a light switch. The 465 with a cast wheel is linear, and it flows a lot at low pressure ratios. I'm driving his truck around this week and accelerating in city traffic(brief acceleration to 50 mph and keeping up with traffic), I don't ever need more than 5 psi. You can probably hit 5 psi on a S465 in compounds on a 12 valve by 1800 rpm or even less.

467.5/83/1.0 housing right now it starts coming up on boost around 1800 rpm. Just trying to figure out a setup for next year racing season.

If you use the exact same turbo as a secondary it will be just a touch slower than it is as a single. You could drop down to the .90 housing to gain some spool, but you may require an external gate.
