quick question I probley need to call Don but will ask you all first. I have mach 4's and want to go bigger 5's or 6's. dont know if it will be easier to find someone that wants to down grade, sell these, or how much bigger Don could make these if I sent them back?

 

post it you'll be surprised, i've seen some ads that they want to downgrade

 

4's can easily be made into 5's and 6's. the cost is around 3-4 bills

 

thank you sir, I just sent them to you well Rip at source did. had them cleaned and re poped due to engine rebuild should of then when you had them.

 

Don M, I have a set of mach 1.5's can thay be made into Mach 3's?

 

not sure but i thought only mach 4's and higher could be changed due to they have a different tip material. ???

 

I have 5's, but want 7's. LOL

 

I would call these guys, they seem to build some decent sticks at a decent price. We have a few in a few trucks here. They make decent power, at less smoke and egt's than the F1's

I have a set being built for my 12v race truck

You really don't see to much difference between the mach 4's to mach 6's. The trick is getting all that extra fuel to burn completely.

 

thanks for the other source to look at never even heard of them before.

 

Ya they build some big bad sticks. I have some big custom 24v sticks coming in shortly 5lpm 6X20, set-up for 13mm P pump. Hoping to break well into the 1000rwhp club with them and costs less than my mach 6's did.

 

I have even more good things about them since this thread posted. they seem like they are starting to shake some trees and get more and more noticed. funny how that works when you have a good product.

 

I would like to buy some 1.6's maybe.

Agreed, I would like to do some comparisions between most of the big name injector outfits. SDX is the first outfit that actually seemed decent to work with to get what you wanted.

Nothing bad to say about don's injectors, they are very very good sticks.

 

You won't regret it!

 

If your running a stock turbo or tow go with the 1.6's

If you have an aftermarket turbo, get the 2.0's They make decent power and aren't to smokey if you have the right turbo set-up. You can probably get to around 450rwhp area with them
