I was just wondering if anyone on here is running them and how they liked them? I was also wondering what turbo/turbos you guys would suggest running with these injectors? Also how are egts with these injectors?

I'm running Mach 4's and love them, very clean injector. Worked we'll with a stock turbo and edge, lots of smoke on level 5 but expected for that size of injector. Not sure how big of a turbo you'd want for Mach 7s but they are good injectors

Love my Mach 4's as well. There are a couple of guys running Mach 7's with compound turbo setups. Maybe they will chime in.

I was running mach 6's (20 hp smaller then 7's) with the compounds in my Sig for about 16 months and absolutely loved them. Made 628 hp with em, never saw over 1450 degrees under full throttle with everything turned up, low smoke for the size injector. That was pre cam, valve springs, push rods and tunnel ram grid heater delete.
I'd suggest them to anyone that has the coin. But I love my sticks from Weston as well.

You can see the vid of 618 on you tube under Cummins dyno 600+ hp, it's a red 2nd gen, sorry can't post the link through my phone's YouTube.

Here it is,

Man, the smoke really clears up nicely at full chat.:thumbsup:

I'm running Mach 7's also with whats in my sig. I have run Mach #1.6, #4, #6 & now have #7's. I also have very little if any visable haze at idle.

Thanks guys that's basically what I've read is that everyone love their mach injectors. I was also wondering if the guys running the mach 7's are running a SO pump or a aftermarket one? I've heard guys say that you can run an SO pump with big injectors as long as you have enough the fuel to the pump. If that's the case what psi would be safe to be running for these injectors? Also I've been torn between a mechanical lift pump and a fass 150 i think they would both supply enough fuel but i was just wondering your guys thoughts on this? I have an in tank lift pump right now and want something better.

I ran 7s for years. Best injector I ever ran. Made 613 with a blown head gasket and intake plate gasket. Super clean setup with a 62/65-12 over S475. Running 5s now,200hp, with a single 62 and like it. Probably going to look at a 472 to put under it for a nice quick tow setup. Can't go wrong though!

I'm running and sovp 44 and a fass 95 holds 14-15 psi all day and doesn't drop when I'm on it!

I love mine also, running it with an ED 66, it hazes a bit more than guys with twins but they are sweet and cleaner than others I have run. Ran a 12.3 with them and supporting mods!

Mach 7's on a Silver 64 smokes too much at idle for my liking. I will go back to my Mach 6's. They were quite a bit cleaner. Although I have a marine head gasket so compression is a bit lower.

I had Mach 6s with my 66 and absolutely loved the set-up. Had no trouble controlling smoke or EGTs. :thumbsup:

Every injector ive ran with my 64 smokes at idle have not ran mach's tho

Compounds will really clean up most dirty sticks anyway
