New base numbers since my drive shaft was fixed 445.32hp and 856tq. Best tq number was 861tq and 444.42 hp. This is still before manifold.
Why are those numbers so low? What nozzle sizes are on those 175s? After looking at their site, I'm assuming the Industrial Injection turbo you have is just a Powermax. Still, with the Powermax, 175s, RR, and Matt's SRL++.... I would've expected way more than what you put down.
Are there any issues with the truck? Fuel Pressure looks good? Big tires? Having an issue, like a boost leak, would cause the truck to smoke like it did on the dyno. Just curious, because if there's a problem - your test with Steve's manifold won't be accurate at all. Especially if there's a boost leak, the manifold will move that much more, or less, air to make it worse.
Either way, good luck. I offered to get some numbers for this intake manifold a while back. If you're still interested in doing testing like this Steve (before and after) the guys at PHP could make it happen. Hell, since they have a shop now - they could probably test this with multiple trucks.
