Which would be best? Any dyno numbers from guys with the same turbo & either one of those injectors?

rockjeep73

Mach 4's and same turbo did 510 on fuel, 680 with nitrous

Flatbed24v

no numbers here nor have I ran either one but from what I gathered in research I am going to get a set of Mach 4's they are suppose to be high quality and able to be daily driven and have better atomization and will produce the 150 hp. I am no expert but that is what I am going to run once I get the cash

J Lent

Nice. I saw on the II website that Brady is rating my Dragon flies at 100hp. When I bought them, they were rated at 150hp. How were your egts with that combo? Smokey?

rockjeep73

it will get hot while towing heavy and i have to keep an eye on it, but normal everyday driving is fine.

J Lent

I tow 15k+. I had a set of Dragon flow 10 holes before & they were too hott.

rockjeep73

not sure how they would be for you since i have a hot rod pump

EBunger

If you can keep rpm above 2200 towing heavy you shouldnt have a problem.

I know of a couple sets of injectors for sale.
1. DDP150's $500
2. II 10 hole Dragons $600.

I'm considering them, but I may want bigger & swap before my pulls, but I hate to do that. I wonder how the DDP's compare to M4's?

Mountaineer

Jamie, I don't know if the M4's would be a improvement over your current sticks going from these fuel numbers.

OK lets just start with I know a certain someone that raved like in every imaginable injector thread about Dragon Flys and how awesome they are.
Now just because Brady typed some stuff on his computer doesn't change the performance those injectors.

So why are you considering them again if they were to hot before?

I am just kinda shocked to see the thread, I thought there was no closer bond between man and his injectors.

DDP 150's! And if you do not like them DDP Will take them back and either upgrade them to the 200's or downgrade them!

J Lent

I was thinking the same thing. I know I've got those numbers under the hood already. I actually started this thread because I wanted a giant set of injectors to throw in only when pulling. Then a couple pms later, guys got me thinking a DDP 150 will be stronger & cooler than my Dragons. I got beat at the sled pull Saturday by a guy who I usually beat by 10-20 feet. His only change was a monster pump. This makes me think that since I know I've got the revs, maybe I just need more fuel. I ran the 10 holes before with a 64/65/14 turbo & didn't like the smoke, II told me the new 10 holes are better. I don't know what I'm thinking.

Mach 4's make more power than DDP 150's with less smoke. Neither one is a big injector.

J Lent

I know those 2 aren't big. I wanted a 200+hp injector, but kinda got off track. I love my Dragons for daily driving, just thinking bigger for track.

Brokenarrow

DDP Comps then! Or if your looking extreme go with scheids lighting 4's or 5's there somewhere in the 300hp range! But there not driveable at all! Im looking into a set next year!
