KTA wrote:SO I have been doing some 14mm testing and have discovered several issues. With the particular fuel screw in this pump and control lever assembly the fuel screw is capable of moving the control collar its maximum distance. A longer fuel screw in this particular pump would only result in bending the lever over like lots of people do putting a gov spring in wrong. From the two 205 pumps I have sitting here they are both that way so it looks like to me anybody that is welding up the tip on their screw to turn it in further is probably doing internal damage. Anyways this pumnp is setup in a normal single feed setup with a 386 spring and linkage travel maximized. The fuel cone is ground and set at max fuel position. The 1st thing I noticed was that the pump needed in excess of 30psi at anything over 1500rpm to keep fueling up, and even then it is falling off bad. At high rpms I am running 80+psi inlet pressure and still cant keep fuel delivery and case pressure up. This is why I think alot of 14mm VE's die. You HAVE TO run a ton of fuel pressure or it essentialy keeps running dry and it scores the plunger. I also tried a 354 spring but even at 4000rpm I didn't gain anything with it. I don't yet know if this is because the pump just cant flow at those speeds yet or if it is governor related.
Flowed with my 6x.018 injectors
RPM Flow Power
1500 460cc 460rwhp
2000 420cc 525rwhp
3000 360cc 677rwhp
3500 320cc 702rwhp
3600 310cc 699rwhp
3800 290cc 690rwhp
4000 250cc 626rwhp
So it looks like 700 on fuel is possible with enough tweaking but all the stars would have to be in alignment for sure!!!
