Yep especially with the 12's got to watch that 1200 + danger zone sustained. Not interested in melting pistons.
So how do you like your DDP Sticks? I was talked into SDX which I had issues with. Had two bad injectors right of the start. Seals in the injector body were pinched. Leaked fuel out from the injection body. Found it right away as my fuel pressure tanked.. Anyway thinking I might try the DDP route next.

great wont lie, but when you haven't let your pickup warm up and get on it 1st makes a pop ' im told thats just 140s' and their revamped marines, spray angle is to wide so when you advanced timing past 16.5 it sprays outside piston bowl, but that can be helped with .6mm copper washers, funny thing is i was gonna go with sdx's when i build my engine this fall, you might try industrial injections that was my plan b

Yeah not that impressed so far with SDX. Customer service is crap. They would only send me one replacement injector at a time. Haven't had the pop issue and the timing I'm running seems to be working well. Get what you pay for I guess SDX is like half the cost of DDP. Wish Don at F1 still made the HR370's. I'll probably go DDP next.

You are the 1st issue I have ever heard of with SDX, they are cheeper than DDP injectors and if you wish to try a set of DDP be my guest ... but your not going to like them. Its great to pay 900+ for a set of injectors that run worse than a stock set.
