mod help. injectors
For my obs. Ive already decided on stage 1's, rosewoods are 160 and others are 165cc. It is more of a grocery getter but sometimes pulls 4 to 7000 lbs. truck has 300,000 on it and only replaced the clutch a few times and the water pump. hpop seems to be okay for know and i have an intercooler and all the stuff just waiting to install. i want to be around 350 to the ground. will i notice 5 cc on the injectors or does anyone have any thoughts?

I can bump Stage-1's to meet any cc you see out there for little, if any extra cost (depends how much more.)
I stick with 160 cc because you will be pushing a 17° HPOP to it's limits. Even a few more cc's will drop your oil pressure and you would probably loose power than gain any, without having to drop even more money on a larger HPOP.
5 or 10 cc won't be noticed through your seat, but you will see HPOil pressure drop due to more stroke.
IMO you won't quite see 350 hp with Stage-1's. Even with an intercooler, e-fuel, and a larger turbo you're looking at maybe 340-ish. This is what we see on our local dyno. You may see or read others in the upper 300's on Stage-1's, just find out what a stock truck does on that dyno before the mods. After a little math I doubt you'll find more than a 140 hp or so gain over stock with just Stage-1's. Some dynos tend to read high. Keep in mind the OBS are rated at around 210 - 215 at the motor, and we see a stock truck around 180 hp at the wheels on the dyno, which is pretty realistic.

That was the case for me for sure. If you don't tow much it will work, just won't fully supply the injectors and you won't get the most power and may set a cel at wot. Mine would set a cel at wot if I was empty, set it REAL easy if I was pulling my trailer.

Exactly.
A stock 15° won't support anything other than stock injectors.
Of course you can run Stage-1's with no issue as long as you keep in a low 60 or 80 hp tune. But crank it up to it's full potential like a 140 hp tune and you will need a larger HPOP.
I've done a few 200/30% Hybrid sets. They have completely different flow characteristics than your typical Stage-2 that produces about the same hp, and use less HPOil doing so. I'd bet a 15° would work well with those, and make good power with stock turbo. They are capable of pushing a lot of fuel, more than your typical Stage-2, so an upgraded fuel system would be required. Or keep to lower hp tunes and the stock fuel should be OK.
I see no point in a 205/100% Hybrid. If you want that large of a nozzle, just go the normal 238/100% and de-tune them. They should cost the same and will be worth more money if you decide to sell them or upgrade later.

Joey at Terminator Engineering can mod your pump for you. Since you have a 97, a Superduty pump will also work for you.

Email Joey, I'm not talking about his HPOS1 and HPOS2 pumps. He can mod your pump to a 17* pump for alot cheaper than that. Send him an email and ask about it. You will be surprised with the price.

They flow a little more fuel than your common Stage-1's, then crank up the pulsewidth and they will push about 40 cc more.
I've had some positive feedback from those that have run them.
Benefits are you get all new parts (which almost all AA's need anyway) and can keep the stock 15° HPOP since they have less stroke than a Stage-1. And are cheap to upgrade to full Stage-3's later on if you want.

Boy, this is confusing, a 200/30 that flows more fuel then a stage 1 but can be run with a stock 15* pump where a stage 1 can't, and make more power to boot.... Can you help me under stand this.
How do they compare cost wise to stage 1's
Thanks
