I can't believe it. There's simply no way a 150hp injectors can be easily street driven, right? They smoke like nuts, right?
Well, the most amazing thing with the Mach 4s over the DD2s is the smoke threshold. I could drive my DD2 smokelessly, but it took a little concentration.
With the Mach 4s, you can accelerate normally without worry about smoke! Granted, your "normal" will a little quicker after putting them in, but smokeless acceleration is easily achieved.
That said, they WILL smoke if you want! LOTS OF IT! Just mash it at too- low rpm and you can almost put the fire out.
These are JUST what I was looking for smoke-wise-- *I* control the smoke. The throttle is more sensitive (of course), but it's about the same as the 75hp injectors with an EZ set on most aggressive. I have NO other fueling mods at this point (sold the box).
So, I'm testing them with JUST the M4s, no box, no boost fooler, no nothing. Well, nothing besides my super-duper PowerCore BHAF
At steady cruise, EGT is about 50-100 degrees cooler. Get into the pedal, and they race higher-- very quickly. But I can still get up to 70mph before the temps hit 1400.
Some other notes:
-- boost is limited to the stock 21psi, so my results are based on that (WG is NOT blocked).
-- MPG was 20.5 based on a 130 mile hwy jaunt with LOTS of hot rodding and mostly WOT stuff. It appears these will net better mpg over then honed sticks. Same conditions with previous sticks got me about 18.5mpg.
-- Again, truck is setup with NO power chip or boost fooler at this point. (I'm between electronic bombs after selling the EZ and saving for/stewing on what's next)
-- My altitude here is 6000+ feet! Yes, they have fullY controllable smoke AT ALTITUDE.
-- Any hint of lag past 10psi or so is gone--- response is instantaneous. Lotsa fun on the hwy.
These sticks should take me as far as my HO pump will let me go. They should be the last set I ever buy!
Don M and Bob Wagner, thanks for being patient with me! Don, these are the best streetable sticks I have ever seen! LOVE THEM!
