Hey all. As you can see in my sig Im currently running F1 Mach 6's. They are not 220 Mach's though, they are 210's. And Im wanting bigger.
At 60 lbs boost I max out at 1320-1350 egt's so Im not worried there.
I'd like to stick with F1 cause I love the injector so much. Out of them and the 3 other sets Ive had while building, they smoke the least, make dam good power and run the coolest.
Im wonder if you all think it would be worth is to spend the 500 upgrade to Mach 7's. I know its only a 30 hp differance, but I dont want an extrude honed nozzle from II DAP or DDP. I want quility! Which is exactly what the F1's are. I just wish Don made a 275 or 300.
Anyway have any of you ever ran the Mach 6's AND 7's? Noticed much differance?

TIA Ian

What pump you running? What condition is your head in?

You could drop the pop pressure and find someone to extrude hone the nozzles from more.

What nozzle is your mach injectors based? I seemed to make more power with 5 and 6 hole injectors.
