LT1 "style" dry setup on mafless SD tuned LS1, with adj FPR. The way I'm thinking of it you could run multiple stages too. But lets not get that far yet. I'm just wondering if this will work on our 59 psi fuel systems like it does on LT1's. I see no reason why it wouldn't.

Thoughts?

 

You thinking of using a Boost referenced FPR or how you going to control the addition of extra fuel?

 

I'm wondering the same thing as CAT, but the problem with that is that a boost referenced FPR will only add addition fuel when it sees boost, which a nitrous system doesn't not pressurize the intake enough to reach even 1psi of boost. So I don't think the boost reference regulator would work in this situation.

 

It has nothing to do with intake pressure. It has everything to do with the pressure inside the nitrous line. You use NOS part #15850 Nitrous Pressure Regulator tee'd off the nitrous line after the solenoid. That unit sends a certain amount of pressure to the FPR. You adjust the amount of pressure with jets just like in the nitrous line.

The LT1 kit raises FP from 40-45 to 80-85 to achive extra fueling on the stock 24lb injectors. I think with some creativity in injector selection and the jetting of the pressure to the FPR, us LS1's could achive the same thing.

Take a look at page 10 on this PDF and item (14) is the nitrous pressure regulator. You'll understand it from there- http://www.holley.com/data/Products/...135-SNOS-1.pdf

The NOS 5.0 Mustang dry kits work the same way.

 

I see what you mean now.....I think I'll stick with wet, lol. Really though, it looks like it could work on an LS1.

 

Of course you would, it's only natural. You guys don't make a dry kit (unfortunately) so it would be marketing suicide for you to run dry.



The only issue I can see is that our systems already run about 15 psi more than LT1's on average. And what is the safe limit for boosting fuel pressure before you run into injector problems? 85,90,95psi? The room to "grow" might not be there on an LS1 like an LT1.

I think this would be an option to run a dry without a maf on an LS1. Or, if you run out of maf frequency you could use another dry stage to boost FP.

 

Uh are you sure NX doesnt have a Dry Kit? I think they do

 

It doesn't have anything to do with who I work for . I prefer wet over dry for a number of reasons that don't have anything to do with NX, which happens to have several dry systems that we produce as off the shelf systems. Plus, we can build any nitrous system that a customer wants, including dry if that's what they request. It's just a personal preference for me, and my posts on here or any other message board are mine and not NX's. If I thought that a dry system would work better in a particular application I would say so.

Don't get me wrong, I'm all for creative ideas for new setups and trying new things. However, when I personally am trying to come up with a new setup or a new way of doing something I am looking to make things easier (ie: quicker/easier installation, easier/more accurate tuning, better performance, etc.). This setup seems to me to be a little more complex, harder to tune, and basically a step backward in technology on the LSx engines. That's why I would prefer to stick with wet in this situation if you are really wanting to use Speed Density.

Again, these are just my opinions and not those of NX, which really don't amount to anything if someone doesn't happen to agree with them.

Just differing opinions that's all.

 

Yeah me too.

 

I'm just busting your *****. I prefer dry because I believe you can safely stuff more dry HP thru an LS1 manifold than you can wet, in a non-direct port application. I do run all NX solenoids though.

What dry kits do you make?



If I ever commit to SD full time I might do the setup I have been thinking about.

 

That's cool, a little ball busting from time to time keeps everyone on their toes, lol.

We have a dry systems for motorcycles, diesels, pocket bikes, carburated engines, and we've done several custom dry systems for EFI engines. In fact, one of our custom dry systems is currently receiving alot of scrutiny in one of the Outlaw racing organizations up North. I don't want to say too much about it, but it's definately breaking the rules and hauling ***, lol.

If you ever get around to trying this setup I hope it works great and if there's ever anything I can do to help I'd be more than happy to even if it's not NX parts.
