For what it's worth, gov springs don't add any hp. All they do is keep the truck from defueling under high rpm's. It feels like more power, but it's not. I added my springs and a 11 plate at the same time. After putting it back together the truck ran exactly the same on my 'test hill' which isn't exact science, but it is a repeatable test. Found out with some reading the rack was getting stuck under my plate so I had to do the gov. arm adjustment. Suddenly truck was making 30 psi (from about 16) of boost and my test hill speeds went up about 25 mph, which is huge since it's a short hill. I never dyno tested until after the work was done but the truck made about 95 hp over stock rating on a load test dyno and about 130 hp over stock on a non-load dyno. Several years later, I ground my stock plate to a #100 and the truck would now make 40 psi boost with a noticable difference in the SOP dyno. Test hill made another 8-10 mph.

 

Turbo23, study the pump..
Don't believe it if you want, you can remove the fuel plate if you want and over-fuel like all the kids do. At least I'll know mine will run correctly.

 

dude sorry to bash but on the other post your on guessing HP, you say he might have 260? WTF if you go by your math the guy should have 400 hell he said he already has a fuel plate that adds 100hp sooooo....... what about his other mods? why the low guess i can only stipulate because the #'s arnt in your favor. ive got these pumps pretty figured out. by far and away no expert but understand how to build efficient HP and TQ quite well. a HP guess is all it is a guess. the more stock the engine the less ponies your gonna pump out with the same mods a 1000 hp rig can. a 250 shot a funny gas isnt gonna give you 250hp on a stock truck but on a 600hp if very well could. EVERYTHING is a variable with HP and TQ and with a mild built engine your on the low side of everything.
its HYPE to get you to buy their product

First of all trying to guess your horsepower is silly, so if you're going to guess you should be conservative.
Second, I didn't see him specify his year and transmission.
If he has a 1994 automatic how much power do you think it puts to the ground?

The rated engine power and what it puts to the ground are very much different.. grasshoppa

So, my estimate of 260-275HP may actually be right on, we won't know unless he runs it on a dyno. 300+ at the crank may only be 260-270 at the wheels.

 

these fuel plates work on any stock truck and gain a great deal of power. you are only looking at the potential amount of power the plate can make with what pump it is what tranny it is what barrels and plungers and delivery valves and injectors and gov. springs. so with that said if a #10 plate says it will make so much hp it has the potential to do so. i have twins 140hp injectors full cuts 5k gov spring #0 plate and 0.93 oversized lines with a ported and polished head and 60lb springs thats fire ringed when i had a #100 plate in it with this setup i didnt see but 500hp a went to the #0 plate i gained gained= less smoke 70rwhp and it will hit a good lick at adle.

 

I put a #10 in my. It made a big difference. my stock clutch wouldn't hold it. It cost my 1200 for a new clutch
