Well I finaly got my pump stand going and ran some pumps with my 6x.018" injectors. Thanks to multiple modifications I made I now have the ability to flow a pump with the Injectors it will be run with. I started with a pump I had off a burned up engine I parted out to see if the pump was any good, to get some base line numbers, and so if something went wrong I didn't wreck a customers pump.
The pump tested was a non intercooled pump and it still had the collar on the fuel screw but it was turned all the way in I also rotated the fuel cone and ran it with it at its deepest point only. I am certain these big flow numbers are the reason why big injectors are the key to power with the VE Regardess here are the results all at 1000stk and 12psi fuel pressure. I ran 30psi also but the results were the same. As a side note I accidently cranked it to 50 once and it didn't blow the seal out.
800rpm/idle 7cc
1000rpm wot 170cc
1500rpm wot 185cc
2000rpm wot 185cc
2200rpm wot 186cc
2400rpm wot 190cc
2500rpm wot 180cc
2600rpm wot 132cc
3000rpm wot 26cc
So with these settings it looks like if you burned all the fuel at 190ccX2 = 380 engine hp then X by 80% for drivetrain losses and you have a nice 304rwhp. Well it probably wouldn't actualy be to nice as these injectors would be awefuly doggy and smokey for only 300rwhp, but that isn't the point of this post.
Here are the results of a customer and member heres pump after doing the usual tweaks. It is a intercooled pump with the fuel screw maxed where I could just get the idle set right, cone turned and run at shallowest point.
800rpm/idle 7cc
1500rpm wot 180cc
2000rpm wot 200cc
2200rpm wot 200cc
2500rpm wot 190cc
2600rpm wot 180cc
3000rpm wot 45cc
with the cone at its deepest the peak fuel delivery at 2200rpm was 300cc!! I guess that is about right 300cc X2= 600engine hp
Then take 600engine hp * 80% to account for drivetrain losses in a manual and you have 480rwhp. And since that has been done before with these very injectors I am going to say this all seems pretty reasonable.
When I get some more tools, fittings and adapters made I will be finding out a lot more about the actual operation of the VE and as I do I will share what I find. One thing of note if you forget to turn on the fuel supply pump and you make the VE suck it it only delivers about half the fuel so for best performance you need a steady supply of at least 8psi fuel!
