What do you guys think is the sb66 enough air for the mach 7's? I have mach 4's in it now and it clears them up great and keeps egts in check. Wanting to sled pull a couple times a year didn't know how the 7's would do with this turbo while hooked to the sled.
 
It'll work great...one if the firepunk trucks has SO VP, drag comp, Mach 7s,66/74/14/ p&p head and made 618hp1140tq runs 12.34@109...its also a daily driver
 
Get some sheid lightning 2s youll like them better and they will make more power
 
Too big of a jump. I'd get some M5's or 6's at best. Overfueling does not mean more power, you need a equal balance of fuel/air.

I did 611hp with stock "untouched" head and no tuning. I'm hoping to break 650hp with just Mach 5's and a Super B Special. I have no doubt in my mind that I will be close to that. I don't only daily drive mine, but I tow 18k# with very minimal smoke. My vote is for Mach 6's.

Thank you thats exactly what I was wanting to find out. Thats pretty much what I have now except for the P&P head but planning on having that done this winter and adding the mach 7's
 
personally we have a mach 6 truck and two mach 7 trucks and the are both such a clean injector that you can get by without smoke for daily driving. The difference between the two sticks isn't really noticeable until peak HP.

If I recall the 6,7, and 8's are very similar nozzles, just different internal workings. Been awhile, hopefully Don will chime in.

I think I am overfueled and made less power than Jamie with a 64/74/14 and DDP comps.
 
Some trucks just dyno better then others... I have seen identical setups dyno 75HP difference... Every truck has his own personality!

Are those the same Injectors I sold you?




I went 12.20@110 with 7's and an s465 and 4:10 gears and bone stock head/ bottom end. They make good power. Hell I went 12.83 with the same set up only with an HTT 62/71/13.
 
There is nothing about Mach 7's and a SB66 that says overfueled. I am sure you will like it and make great power.
