Aftermarket HPOP

Hello,

I've currently got an intake, 4" exhaust, and Wildman tunes. The truck still lacks as much power as I would like on the top end. From those who have experienced it, does an aftermarket HPOP like Adrenaline make a noticeable power difference in the higher RPMs with stock injectors? If so then this will be my next mod..

Thanks.

Nobody has felt the difference an aftermarket HPOP makes in high RPM power?

you should gets some numbers from your pump with a good scanner like an AE and find out your pressures.How many miles on your pump? I had mine modded from Joey@ Terminator for 100.bucks might want to check him out and i also heard good thinks about the Adrenaline pump too.

If your pump will provide the pressure that Tony is asking for ..save your money for inj's.

Truck has about 78K on the clock. Check engine light comes on at high RPMs in 2nd gear on the Extreme setting. I've done the zener diode boost fooler so I'm not over boosting. I'm assuming it's the HPOP maxing out but I guess I should get a scanner to see for sure.

There is no defuel on the Super Duty trucks regardless of boost amount. There is an overboost code that reduces the cycle time of the IPR. The result is a slower gain in acceleration, not a reduction of fuel. The way to see if you are setting this would be to scan for the code. This is off the top of my head and it may be wrong, but I think it is a P0236 that is the code. You can set them on 94-97's, but it is a higher differential than the 99-03's. I run a MAP Pressure Relief Valve on my 95.

However, I've seen various configurations of MAP sensor alterations and I would warn that most are ill conceived. The majority of the pressure relief set ups I've seen blow off actual boost and do not isolate excess boost to the MAP side only, leaving the manifold pressure able to rise. The electric modifications don't allow MDFR (Mass Desired Fuel Rate) on the low end early enough since they mitigate the overall boost by a percentage.

How much extra pressure are you getting out of that 100 buck pump modding from Terminator? I'm not looking to build more than about 400WHP because I don't plan on Forging my motor (right now at least). Sounds like this may be the way to go for me if the modded pump can handle that kind of power...

Any good injector options out there for less than a grand that can push 400WHP?

Never test for prussure on that pump, but I can fill the difference for my old stock pump. Just shoot him an email and he can answer all your question.
