Just seeing what people might thing about that......

Please, dont hold back...

 

Sounds fast

 

sounds cheaper

 

Sounds Sketchy.....................









But I have a few ideas as well as some stuff floating around about how to make a serious db2... And I plan to do it reliably...

Since I cant do my 60 swap cause Im a gimp... I have a little project underway... Thats all Im going to say until I have something concrete to show...

Lets just say, Im substantially more well versed in these pumps than I was a couple months ago, and couple that with me being a Machinist and possibly having access to a CNC shop... Anything can happen...

 

I'll be the test dummy!

 

i like where this is going. You going to try and increase the governor on it, or would it handle it? Id be a test dummy too if the deal is right, i need something to tide me over till i can get around to my inline'd engine.

 

You're going to need a lot more fuel than his DB2 is going to put out

 

On my 91?! with it n/a again? Lol

 

Sounds good if the price wasn't crazy.

 

Im going to be the test dummy first, I have several pumps to toy with, and my current pump that is on the truck, I am going to leave totally stock, and in a matter of an hour, I can have a running truck if the test pump decides to ***** the bed. My first pump will be a test bed with .400"-.470" Plungers, a new input shaft, Cam pin, modified rotor and head, with a little cam ring work. Im kicking around building my own test bench if I cant find a local dealer with a bench that will work with me.

If I can make the first pump work for me, than I have a plan for a pump that will put out HUGE fuel... It will require a new head and rotor to be able to push that much fuel under RPM... Which is where these pumps are limited (a 4 cylinder pump can be made to put out more fuel per injector than an 8cyl pump), and why im pretty sure a certain truck in question is having issues with their hot rod pump. I have a design that will work around that though...

 

i got one sittin around you can "redo" for me lol hell ill pay for shipping there and back

 

Oh? do tell more

 

Im not going to tell more right now, I want to progress this a little further first... There is a few people that could grab ahold of my ideas, and that includes the chevy guys... I have a damn good idea for the higher flow pump though... Its right on par with running two pumps...

However, we know this...

The weak link in the pump is the "fuse" and fixing that will mean going a long ways pumping wise.

I also have a great idea for an aneriod controller that isnt the same as the hypermax part, and is easier.

 

So I was tinkering around with the pumps again today, and I finally pulled out the intact shaft out of the other housing so that I could get some dimensions off of it for the new shaft. Well it didnt take me long to find out that these pumps had different shafts and support bearings for the input shaft.

The Turbo Cal pump, which started life as a 93/94 Factory turbo pump, has a roller bearing and Steel? sleeve in the snout that supports the shaft and seals the shaft to the housing, also has 3 seals. The N/A earlier pump just has a bronze bushing the whole length of the snout, and a smaller initial diameter that rides on the bushing, and only 2 seals. I dont think there is a benefit either setup aside from maybe sealing, but its interesting that they changed the design, Maybe for reliability purposes.




Anyway, Just keeping the thread going... Hopefully Ill have a CAD drawing of my input shaft here soon.

Consider this my pump build thread...

 

the writing on the paper towel under the shaft seems kind of fitting.

good luck man!
