Stock Hpop #'s

Carolina444 · Feb 4, 2015

Recently got AE and I was wondering what kinda numbers my stock e99 hpop should see at WOT?

Justin@DP-Tuner · Feb 4, 2015

Stock tune or tune from a chip/programmer?

100 tune

Justin@DP-Tuner · Feb 5, 2015

That can vary greatly depending on the tune. Ideally, you want to see over 2600psi with a duty cycle below 50%, but with hotter tunes it is harder to see those kind of numbers, especially with a stock HPOP.

With a stock tune, you should be able to hold 2800-3000psi with a duty cycle below 50% as well.

^^^ agreed.. Guys with similar stuff (stock pump/split injectors) have reported 22-2300 on high PW files.

Carolina444 · Feb 5, 2015

Ok.. Well it seems like it's well bellow 2600 and higher than 50%.. I will go through all the saved data tomorrow and post it. Thanks for the info

With a 15* and ab's on a 100 hp tune it's prolly gonna be workin it's ass off. Icp is gonna drop prolly 2400 or below and duty cycle will be 60%

Forgot to post some numbers.. I didn't have much time to log today but here's one that looks bad in my opinion.. i was seeing 2300-2600 at WOT with cold oil (110*) is this pump bad?

178* oil temp
73% throttle
70% duty
1743psi

Those numbers are pretty bad, could be injector o-rings, worn injectors, oil rail plug o-rings, but being a 15 degree with quite a few miles its probably a tired hpop.

I've only had the truck 1.5yrs so I have no clue if the injectors and Hpop or originals at 257k.. I did replace the inj orings last winter. Truck seems to run ok

I'm seeing similar readings but it's inconsistent.. I'm also seeing 17-1990 @ 60-70%.

This was on my 100 php tune

Justin@DP-Tuner · Feb 16, 2015

It's likely a mix between worn split shot injectors, a 15* pump, and a hotter tune. Those three things make for a bad combo when it comes to ICP.

mandkole · Feb 16, 2015

^^ agree

Yeah, that pump is likely the original. A new pump would be worthwhile to get the most from the new injs and turbo.

Well just ordered a hbjr to fix my weak pump.. Maybe I can swing the pis injectors next month

tim was running a sale on 175/80's here recently

Called dyno proven back to see what kind of price I could get since I ordered pump and lines earlier today. Jonathan gave me a great deal on some 230/100 and took his time to discuss my options on my build. Looking forward to buying more from these guys soon
