Termy Engineering modded 17* HPOP wide open throttle graphs

Just thought I'd share some graphs with you guys of my truck doing a few wide open throttle runs in 80 econo, 120 race, and 140 aggressive.

I don't have any "before" graphs because I didn't order my AE until after Joey modded my HPOP so sorry, no comparison graphs.

My mods are listed in my sig.

Here is my 80 econo run:


You can see in that above graph, just as I hit 115 MPH, my ICP was holding steady at 3000 PSI with my duty cycle right around 61/62%


-------------------------------
Here is my 120 race run:


This time, in the above graph, you can see as my truck was pulling up to 125 MPH, my ICP actually went just above 3000 PSI with my duty cycle right around the same percentage as my 80 econo run.


-------------------------------
Here is my 140 aggressive run:


In this last graph posted above, as I hit about 115 MPH, you can see my ICP was holding steady at 3000 PSI yet again, but dropped slightly as I continued up to 120 MPH. I wish I had kept on the pedal for a bit longer to see how the PSI held up to the increasing duty cycle demand.

All in all, I am very happy with the results.

I can feel a performance gain. Not sure if I gained any more power because there were no before and after dyno runs performed, but there is a definite performance increase due to the HPOP building pressure faster and holding the pressure better.

Off idle my truck jumps quicker off the line now, and like I stated above, the seat-of-the-pants meter tells me the pressure builds a lot faster and better, pushing the truck into the power band much, much quicker.

I dunno if the price is still the same, you would have to ask Joey, but it cost me $50 bucks and Joey replaces all the o-rings and seals, including the one in the non-serviceable port. If the threads are damaged, it costs a tad more to replace the non-serviceable port. If the threads are ok, just the seal is replaced.

Stewart,
I have Jody's 80e,120,140.
Exhaust 3.5,Air cleaner.
I'm trying to get a gauge on the seat of the pants.
I run in the 1800 to 2400 rpm range at 140. I pulls nice.
(I need to keep it together for several years yet).
Will I feal a noticable seat of the pants in above rpm range?
If so would it compare to the fealing of switching from 80e to 120r ?
Thanks

I don't see it getting any better then that Stewart. The graphs look great, and for 50.00? . Does he do more then change gaskets and o-rings? I think I see something in my future.

He "mods" the 17* and then replaces the seals for you. It is a great deal considering what you get out of it. There is stuff that Joey is working on though that will blow the modded 17* away. Stay tuned.

Those are some great numbers Stewart. Best 50 bucks that can be spent to improve ICP.

That does look really great. I've been thinking about trying this. Wish I had a spare pump to send to Joey so I didn't have any down time.

I feel a difference. It just wants to pull harder.

If you were pulling an 8k lb trailer up a nice, long grade and halfway up the hill your trailer suddenly only weighed 4k lbs, you would "feel" the truck pulling harder, like it got a boost of energy.

It's kind of like that.

Clay doesn't know. I don't even think Joey's wife knows!

Joey keeps that info to himself.

That's what he charged me and others. But I did read over at FDP that he might have upped his price. You'd have to send him an email and ask Joey to be sure.
