Started the QUEST mo pow.

Finally decided on 190cc injectors. Now trying to decide on which nozzles 75% or 100%. I have a powermax stage 2. I also will be upgrading the fuel system soon, but for now going to stay stock. I will be putting in a new hpop since mine has 250k on it. So my question is what would be the difference in the two nozzles, and what numbers should I expect with the setup. I run the Looney extreme, and also have tony's tunes too. What other good tunes are out there for the pomax and these injectors. Thanks in advance.also I'm sending off the FICM for the atlas 40 or 80 can't make up the noggin on that one either.

What are the specs on your powermax stage 2? I think it all depends on what you want. I went with 100% nozzles due to the fact that the tuner I use really likes them. A 75% nozzle in theory should run a little cooler when you tow. Who's injectors are you going to run?

Your going to need more air than that turbo can push to clean up 190s. As far as nozzles go I'd do the 75% because they can flow around 240cc of fuel which is more than enough.

So can a tuner keep me happy with the 190's 75? Until I can get my spare turbo built for them.

You should be fine as long as your turner pulls a little fuel... that should hold you over until you get a bigger turbo

Sounds like you just have a standard pmax with a batmowheel. Should be ok for 175s but will run pretty smokey on 190s
