My stock 4x.012's have got nearly 300k miles on them, and I'm looking to upgrade. Anybody run Contagious 7x.010's?
Why a 7 hole ?
You looking for power upgrade? Or just wanting a good injector?
For better fuel atomization at lower RPM - improves low-end power and burns cleaner.
I would just put new 4x12s in it 7 holes in my experience don't burn fuel any better than a 5 hole
And since both kind are relatively close in price range, why would it simply be a marketing strategy?
The 7-hole is a John Deere nozzle, they are cheap and easy to get, that is the marketing strategy.
So which color tractor dominates the prostock pulling class?
If they are the 148* cone angle they are not bad, I have seen good results on the 1st Gen platform, just not anything I would say is "superior" to a 5-hole nozzle.
I enjoy my 7 hole set....
