You're right, port injection will be better in every aspect minus the cooling aspect.

I'm not going turbo though so how much am I really worried about cooling the charge? Not really worried with a intercooler supercharger.

I'm just looking for the consistant octane rating per cylinder

Can I quote you on this?

Let me guess, you spent some money at a shop to go fast, they told you to do something, you did it, and now you think it's the greatest thing since sliced bread?

I work with 4500 hp blown alchohol motors for a living...I think I can handle a little street motor but thanks for your input

:lurk:

You and Josh are going to get along great! :hide: Going to the shop and spending money for their experience is more my thing, Josh on the other hand...... :leaving:

Would like to see how your idea works out though. Over the years many have talked about doing something similar but never really have seen it pull together. :yesnod:

I'll be sure to post a lot a pictures when it comes time to do it. I'm just taking injectors from our old injection set up on the pro mod

Something like this?

Sharp!!!! I want!!!

That is pretty bad ass!!

How soon do you turn the kit on? Much delay? How would you know if a nozzle got plugged?

Don't go acting like you could afford his setup at 75% off Josh. You know you don't wanna sell house for it. It'll be too hard to get those rusted wheels back on it anyways. :D

I've got a 81 tooth balancer that I'll have available soon if you're running a cog system and interested.

:d...

Same as it was before as a twin nozzle for the turn on, roughly 3-4lbs. Not sure what you mean by delay? It's no different then before, we just have a solenoid in line so the vacuum does not pull the meth in the intake.

The reason we knew we needed this mod was from running a Haltech ECU with 8 EGT's. We noticed that this car with two 15lb nozzles (1050rwhp) had a temp difference of over 300* from the front cylinders to the back. Now the difference is just over 100* as it is and I can play with individual cylinder fueling from there. So I would see it in a log if one clogged very quickly, but there are filters.

Very nice. Has me thinking.

It's certainly on my list. :yesnod:

Aquamist make a range of jets with built in check valves so there is no issue with vac pulling liquid in. Plus it would mean no lag time at all.

Or you could opt for one of their FAV ( Fast Acting Valve ) controlled by an ecu or their controller for proper controlled delivery of liquid instead of relying on the more crude pump speed option.

How can you have a check valve that goes in the direction of flow? It would have to have a 30lb spring in it to over come engine vacuum.

Alky control has them too, but it has to not flow in one direction or the other.. So a valve is needed when on the vacuum side of the throttle body, and there's no lag. It's controlled by the PAC module, power to the pump opens the valve instantly.

Correct, it will have a spring inside stronger than the engine could ever pull via vacuum.

As water injection pressure is always far higher than this, it does what it needs to do. Stops water ingestion during vac, and allows it when pump is active.

they are designed specifically for that purpose.

I wonder if that impedes overall flow after having to over compensate for that spring pressure. Nice product, but I still dont like the plastic lines.

The more I pick up on the many different options that Haltech ECU has the more ingenious it looks! So you can run and monitor every cylinder as apposed to a bank of cylinders and make appropriate fueling changes from there? That's pretty darn impressive especially given the general knowledge that the back cyclinders run hotter than the front, which you all verified through your data, nice work. :thumbs: What program do you use to monitor and make adjustments with that setup? I currently have HPTuners and have been working my way through getting some kind of a grip on it.

Nice setup!

On this particular car with the LS7 intake, it's the front cylinders that run hotter then the back. I thought it might have been from the meth slamming the back of the intake, but if you look into an LS7 intake the front ports are very open to the T/B and I think they just get more airflow because of that.
I do not have flow data to support that though, but it makes sense.

The Haltech can add or subtract fuel per cylinder, with the Sport 2000 it is a set percentage though. Meaning if you add 5% it's going to get it all the time, but you may only need that once your in boost, making the cruising fuel slightly rich in that cylinder. Not a big deal, but not ideal. The new ECU the "Elite", will be able to adjust individual cylinder fueling along with adjustments per MAP setting. So cruise can be equal and in boost ramp up as needed per intake flow.

Pretty cool stuff. :thumbs:
