Regular or pro hx52?
Regular as far as I know.

489/845 12mm, fuel only.
He341 over 67mm hx52.
At that time: HT3B into a 62/14, 181/210 cam, ported head, Hellman IC, Scheid 6x.016s and the other usual mess.What was your turbo/injector setup?
I did 393 at 757 on my 12mm

Since swapped in a 188/220. op:
I didn't really see much of a gain in peak hp as I did broadening the power band. My primary goal in swapping from the 181/210 to the 188/220 was to see the power move to the left in terms of a dyno-plot. The thought being to improve the lower rpm breathing so as to take better advantage of the VE's low rpm fueling.When I swapped the 181/210 for the 188/220 I gained 30-35hp on the same dyno. BC Did you see any gains on the street/track/dyno after the swap?
If anyone is interested.
VERY interesting Stomp. I'm curious as to why you dropped the propane setup? Was your motivation for adding propane in the first place fuel economy rather than power?
Did get the Getrag tag along happily throughout this progression of power increase?

I was only gaining 22.2HP and 49.7hp on the dyno. I bought one of the first kits that Bully Dog made and it worked pretty well for a while until I started turning up the fuel. Since propane is just another fuel I was way over fueled and didn’t have enough air to properly support it with my stock turbo. I did however use it for mileage a couple of times and was gaining 4-5mpg if I left it on during a long trip. I don’t really think it was very cost effective by the time you had to fill up both tanks, but I never really did figure it out because I was young and dumb at the time.
I dropped the propane when I lifted my head and blew the gasket at the track. Propane detonates differently than diesel and I wasn’t really seeing the HP gains that I wanted to so that is the reason I took it off. Well there was that and Ponci told me that he would not work on it anymore if I left the propane system on it.
I also had an experience when I left the propane on and was using my exhaust brake to slow down after showing off to one of my friends. :badidea: I guess it built up and ka-boooom I saw an 8 foot flame come shooting out of my exhaust. Motor started knocking for a couple of seconds and then it leveled out and ran fine. Scared the crap out of me and my buddy when it happened.
As for the Getrag my first one went out before I heard that you actually needed to overfill them by 1 to 1-1/2 quarts of oil. I replace it with a used one and over filled it and I am still running it today. In 2010 Ponci went through it and replaced all of the bearings and shift forks and gave it a once over. He told me the main shaft could be better and we were going to replace it, but we couldn’t find a new one because I guess they don’t make them anymore? He cleaned it up and put it back in.
I don’t think it likes the power, but it has never let me down. For the most part I usually just run in valet at 450hp or so. If it ever decides to go out I will be putting an automatic in its place.

Why did you decide to drop the 14mm pump stomp?
Thanks for the info guys! Where are you finding the best spot for timing to be?
Does the Getrag shift like the 4500? I like your truck do you have anymore pics if it?
Here are some pitures. Sorry if I highjacked the thread.
