Need new transmission - input wanted!

Looking for someone running Don's mach 4 injectors . I got my truck back yesterday and the smoke and heat is insane. My PDR 50 isn't enough with the box turned up. Makes DDSM seem tame.

Those nozzles really put out some fuel! They are definately not for the meek. With the temp and humidity in Florida, I can see why temps can go thermonuclear with Mach 4's, a PEC etc... etc
 
I have a set of custom Don M mach injectors called 4. 8 not quite a 5 & these babys smoke like a freight train. The power is awesome but i need a set of twins to see there full potential as im out of air with my single B-1 charger. Looks like i'll be getting a big brother B-2 to go along with my B-1 in the near future. kurt.
 
Don's bigger injectors are not for mild, daily use. They are take-no-prisoners. The rest of the engine has to be properly set up, and the owner has to "need" that last available bit of power, compromises and all. A laggy turbo and tight torque converter will exaggerate the egt problem, hence your problem.



Today we have a lot of stuff out there that is for daily use, and a lot that is on the ragged edge. A few years ago, we did not have such choices. Choose wisely for your intended purpose. Don has put a lot of study and work into his custom made injectors. They are very effective, but they are not for everyone.

:-laf Joe your post is like advertising Crack to an addict. ;)
 
Todd,



The Mach 4's are a 150hp injector. That means they are very similar to the DD Mega Mentals hp-wise. As DD states these are competition injectors so are the Mach 4's. Many people want to go bigger all the time but dont realize just how big the Mach 4's and up really are. That's why Don tries to keep people at Mach 3's or smaller for everyday driving. Running a large single turbo makes it even worse due to the lag induced by the larger shaft and pinwheels.

I had 2's and they were to hairy for me so Don is custom making me an EDM one for my truck. The 2's were insane though lots of fuel little smoke and all kinds of power over a DD2. I wanted ones to try and have no smoke but the power of a DD2 and Im pretty sure we will achieve this.
