Haisley "HI FLOW CONNECTOR TUBES" anyone?

It still doesnt work usen a key the pumps ECU will correct itself Scheid tried this years ago ..


There is an adjustable gear out there but I dunno if it works I just know of one that was in use
 
You need to advance the cam gear....... This can be done but requires machining to keep thing aligned. Also it only works on trucks with a cam sensor.

I understand that large hone size and poor atomization could lead to a loss in overall performance. But to deny the fact that more fuel burned with proper atomiztion will not produce more power is blatantly foolish.

well, there is this little 71% rule when it comes to sharp edged holes holes.

Basicly you can only use 71% of it's actual cross section as the effective hole area.
 
so if I run the larger tubes and stock lines all Ill gain is a lope and no performance or hurt the performance..... Im seeing its a shot in the dark at this point, the thread is turning out to be a pretty good one though!!! hahah:pop:

All VP44 equipped trucks use a cam position sensor, you can advance the cam with an offset VP44 key but it works oh so well...:confused:

Didn't someone just say scheids tried messing with the key and the VP ECU corrected itself?

So let me get this straight, using 71% of a larger diameter hole does not mean more volume if you are using 71% of the smaller diameter hole? Man, some of the brightest minds of today come together on the internet to share in their bliss don't they?

I'm guessing he was putting a little more emphasis on the sharp edge part. A hole with different or more smooth edges and transitions is able to flow more whatever effectively than a hole with sharp edges, because the sharp edges create an eddy type effect ultimately restricting flow. I could see this being the type of thing that really brings machining techniques and design down to a specific science that can play a big role in how things preform.

Its kind of like doing a port job or headers instead of a manifold. Less harsh turns and smoother edges makes things flow easier, even through a smaller hole. Which in turn could lead to better atomization

As far as I am concerned the larger connector tubes are needed with anything larger (and including) a 7x.014 injector. Without using a dyno, Craig Johnson proved that the connector tubes made power on a drag strip, same day, same track, lower ET and bigger MPH. I ran them in the pull truck and later added bigger lines, which I believe made more power, they were enough to let me stay on top of a pretty loose charger. I don't have dyno numbers but this was all done with a redline, stacked with a drag comp, big lines, big connector tubes and 7x.020 injectors. Stock cam, headgasket, and bottom end.

THX Tom for the input I may have 2nd thoughts on my lines now, should have another set of injectors soon close to what you spoke of

i wouldnt say they have a good reputation. they sell an unproven "idea", that the price has been raised 3 times now from 90 to 150. they copy engine design from others that have been running the same setup for a year, there is no more rock hard ram, off constantly barely makes it off the line, and further more they dont stand by any of their products, that is if you can ever get ahold of them to find out anything. ive had my rounds with Haisley "machine", spent a bunch of money there, sent them a bunch of business, and now ive taken all that business plus some back. theyre the reason i started my own company.

i used to have their conn tubes (.093) and matching scheid lines with 7x.012 injectors, the truck idled like crap, and all the time, and didnt make anymore power. unless you are doing it for the idle sound keep your money.

LOL... my buddy ordered .093's and didnt like how they idled, called em up and they're making him a set of .078's and not even making him send his cores back with the .093's, very good customer service if you ask me, half the companies you call anymore you get some dickweed operator that doesnt know his azz from a hole in the ground. Also price is only 120 as of monday, matter of fact I talked to em for about 45 minutes about some things, very personable if you ask me...but hey cant please everyone I guess.
 
just wait until you need work done, or parts fail. i mean expensive stuff, not lines, tubes, etc. how about repeated transmission failures with their nv4500, 4 failures in 6 weeks. even though when i purchased it there was a warranty, that went out the door when i took it back. never pulled, never raced, and the last 2 times it broke i had 275 injectors and a stock charger. and i was breaking it with "too much power".

everyone local to them knows enough to stay away.

sorry about the hijack, and all vp trucks have crank sensors, i know the 02 has a cam sensor, and the 01 slips my mind right now

Hmmm, After reading what I wrote I goofed :doh: What I should have said was trucks without a crank sensor (01-02).
 
doug i thought all had crank sensors and the 01 and 02 they added a cam sensor as well? i may be wrong, wouldnt be the first time
 
feelmecummin, for what it is worth, I just searched my .pdf copy of the maintenance manual and only found "crank sensor" in the descriptions of the error codes and didn't find any occurances of "cam sensor". That don't mean it ain't there, but surely if the 01's and 02's had them they'd show up in here.
 
Nice find. I'm not an 'internal engine' guru so I'm soaking this all up. Thanks.
 
my 2000 does not.
smokem whats your build date?
that guy, if there are both then explain to me why the 98.5 to 2000 relies solely on the crank sensor for timing.
