Westers garage offers a new electronic pump for the 6.5's with the increased fuel rate, 92mm where stock is 80mm. No other info on the site about it. Seeing how they are doing all the ecm programs they may know something about power out of the 6.5's. Anyone look into it or read about it?

They might be doing something with the new 5827 pump, different FSOL and camring, used in AMGeneral apps, just started production last year.

Its also possible they're using the cam ring from 5068 pumps, which I posted earleir produces similair outputs.

Well i drove by there shop yesterday, maybe i can get in on monday or tuesday and find out (maybe get dyno'd too), at the very minimum its a local phone call for me to find out as i'm working in the area.

Yeah, let us know anything you can find out specifically about what their trick is for these HO DS pumps. We had some programmer call us asking about what the mechanical limits for fuel delivery on a DS pump were...with both cam rings, and I tried to convince the boss not to divulge such information for free, but to exchange some information about their programming. He didn't say who they were with, but I wonder if it was Wester's....

Because i don't know pumps i probably won't get the info you want, but if they're putting out pumps like that i'll probably be their first sale!

Let's say it together, "engine longevity".

And as Tim the Tool Man Tailor would say, "More Power"!

I myself would rather play with the power aspect. Others would rather go for longevity... thats cool. To each his own. This is also highly dependent on the pocket book of course, i'm sure if money wasn't an object everyone would lean towards more power.

Is Kennedy trying to get his trucks to go 500,000 miles empty or is 100,000 good enough after kicken butt at a pull-off?

I had a nice visit with the boss at Westers today, chatted for 20 or 30 min's. Yes they are working on a pump to put out 92mm, not ready yet but in the works. Thats all the info i got so don't ask for anymore.

The boss was the only one in today (Valentines Day) and no time to put me on the dyno or do any re-tuning so no numbers for me yet either.Censored

I'll ask the boss tomorrow, forgot about it today, who it was that called asking about fuel quantities with different cam rings. Only someone who knows about these pumps, most likely another fuel shop, would know about the different cam rings, and only a fuel shop that does chips would be interested...that narrows the list down.

I reread the bulletin about the new 5827 pumps, they all come with 3 year warranty and there is a service moratorium in place so we can't touch them, just order a new one, so not likely anyone will have one to play with. I'm pretty sure these guys are using the 30501 (5068) Cam Ring, and trying to figure out the same thing as me, where to set the optic sensor to fool the computer into operating properly and making more fuel/power.

Looks like a step in the right direction though. Maybe we will see 300rwhp someday out of a 6.5

300 reliable rwhp.........drool!!:cool2:

300 RWHP?!?!?? ~250HP at the crank will probably be the upper limit of the electronic pump's capabilities.

and then we add a little propane to the mix...
but i'll have to watch the rear view mirror for parts on the road, lol

300 RWHP?!?!?? ~250HP at the crank will probably be the upper limit of the electronic pump's capabilities.
Based on my dyno testing, I'd say that I'm above 250 hp at the crank. Stock rating for my engine was 190 hp, 385 lb-ft. I don't have any rear wheel horsepower numbers for mine stock, but I do have numbers for a 97. I'm not sure when the power was bumped to 195 hp and 430 lb-ft, but I think it was after 97.

A stock 97 with no muffler and hollow cat made 138 hp and 326 lb-ft. That's a delta of 52 hp and 59 lb-ft loss from published ratings. Take that delta and apply it to my dyno numbers of 223 hp and 428 lb-ft... you get 275 hp and 487 lb-ft at the crank. Due to a glitch with the data filter setting on the dyno, I only had data points recorded every 250 rpm instead of every 50 rpm. Doing some numerical analysis on the data, I project that my peak torque was probably 435 lb-ft at 2350 rpm. Using the same delta, that would equate to 494 lb-ft at the crank. If anything, drive line losses increase with increased loading due to higher friction losses among other things.

I beleive that the higher boost that I was running improved the volumetric efficiency of the engine and recovered some lost hp due to pumping.

275Hp at the crank would be quite impressive, and no doubt you are one of few to even approach that, much less prove it ;)

Kennedy's 96 actually made more power than my Suburban. That may not be the case, though, shortly.:cool:

Apparently Wester's is pretty satisfied with their '92mm DS pumps' They're for sale on their website $1495 CND. Oh, and they want your core, BAD!!! Check the core price...

Hey, If a guy is going to dream, dream big......right?!:exactly:

westers site says the pump is for 96 and up.

I wonder why they would not work on a 94-95?

Tim

Programming, I guess. Perhaps they saw no advantage to providing it to '94-'95 as well.

Sounds like they might have determined there are some compatibility issues on OBDI trucks. Possible I guess, hard to say since no one knows exactly what they are doing different with these things.

I checked these guys web site, and requested info concerning wether or not they will be making these avail. for the 94-95's. Also whether or not you have to have their chip/reflash or if the other aftermarket chip/reflashes will work. I'm not sure if the e-mail went through so if they don't reply I'll retry later. If there IP won't work with other chip's that's gonna bring the cost up to about $2000.

I can not get a hold of westers garage through e-mail, messages keep getting sent back as not deliverable. Has any one else contacted them about the possibility of them making it available for the 94-95. And do you have to run there computer program or will other aftermarket computers work. They're already really proud of this thing at $1500 another $400 or $500 for their programing, borders on unreasonable without some guaranteed performance gains. Even at 40hp that's like $40+ per HP -:t . This has potential to be one of the best performance mod's I've seen for our engines, we definitely need the fuel.

Well, I think we can easily determine what exactly it is their doing. There is only 1 H&R option the 831, and there are just a couple different cam rings so that has to be what they're changing. Also, I mentioned in an earilier thread, that a 5521 pump, with the 30501 cam ring from a 5068 pump will make more fuel than the stock setup, but to get the full 92mm potential, it must be chipped. Heath, Kennedy and Westers chips should all be able to get you that full quantity, just a matter of who's chip you want. But that also means that Westers is not your only option to get a pump from either. Any fuel shop could do the upgrade for you, not for free, maybe you could just get them to do it while your sending a pump in for rebuild anyway, but should be able to get it cheaper than Wester's asking price.

I finally asked my boss about who that programmer guy was calling about fuel outputs on DS pumps...It was Wester's alright. He also said he calls trying to buy large quantities of 5068 cores. So I guess we have indeed figured out their 'secret'.

He's probably selling the cores to me.

Apparently Wester's is pretty satisfied with their '92mm DS pumps' They're for sale on their website $1495 CND. Oh, and they want your core, BAD!!! Check the core price...

Just a clarification the price I saw on the website was $1495 US Dollars.

why don't they just start buying cores from E-bay or other outfits the core charge is a bit on the high side.

Ah Ha Ha Ha!
Apparently wester's doesn't have any secrets at all. Guess who is their new supplier of H.O. DS pumps? None other than yours truly! And thats rebuilt, not cores.

On a side note, when I first heard about these 92mm injection pumps, my first though was, you'd have to be crazy to put that one your truck! But I think I know why they want it...We got our first Duramax in this week, and printed right on the ECM, like many 6.5s out there have on the rad cover, there is a sticker that states fuel delivery quantity @ rated HP. 90.9mm is what a stock DMax puts out, so a 92mm DS pump would give us 6.5ers an advantage in one aspect over the DMax. Now we just have to figure out how to cram enough boost in there to burn all that and not drop the crankshaft.... ;)

so you work for westers now do you TDG:p: :joke:

;) No, but maybe I can get a free performance chip out of the deal for 'testing' purposes ;) ;) ;)

There you go TDG Go for it.
You find a 93 Turbo actuator for me yet?

$#!+ Forgot all about that Bow.

LOL Thats ok
Thanks
