Wow, that's really impressive! I only asked where your pods came from because some guys get flow-matched sets from Piers and the like, where others save a few bucks on e-bay units.

 

well, compared to what this setup should be capable of, i'm just not that impressed yet. i think it'll come around though, once i can just sit on a dyno for a day and try all the things i've been thinking about.

mine were ebay units. paid 370.00 then noticed piers had em for 340.00

 

Looks like the power started to cut out or die out because of lack of fuel on the top end with the stock lift pump. You can see this because of the 'notchy' line around 3000-3200. Either you or the dyno operator let off around 3200 or that '4000' gov spring ain't doing no better than a 3200 gov spring. The 366 spring will or I should say it should fuel to 3200.

It's been proven over that the ebay POD's make good power and are good units. I had them, no way I'm gonna pay another 100 bucks for a set. You think they really reshimmed them Lucas injectors and got them all even??

 

I was jusst going to ask someone to post a pic of a HX35/12 . like yours, installed on a first gen.
I just picked up a rebuilt one. thanx, crossy

 

here are some pics. not much to see. just an hx 35/12.

 

thanks for the info bgilbert a guy on cummins forum pointed out the torque dropping off quick but couldnt tell me why. so the next step will be a different lift pump. the first couple of runs i took it to 3400 but felt like to much then noticed on the dyno sheet i was just wasting time effort and achieving nothing.

 

brian ,thanx for those HX35 pics. I was hoping to see more of that 3.5" exhaust job and your elbow arrangement. I understand thats where the only troubles are. I saved the pics to my files. thanx again, crossy

 

I think it's normal for the torque curve to fall off. More fuel on the top end will net you a little more hp/torque. Plus it will help your injection pump live longer. Since it's lubed by fuel alone the more you can supply it (volume) the longer it will live. Here's my 450hp dyno sheet in my gallery: https://www.dieseltruckresource.com/...0&ppuser=33726.

 

Nice #s bgilbert was that with a single?

 

i dont see any vavle springs in your sig i would think about a set of 60lb springs if you are going to keep pushing it to those kinda rpms

 

Sweet numbers to all who have posted

 

i made 260 rwhp 670 rwtq. not to bad for only spending about 375$.

 

Great numbers!!!!! Congrats!
