Another question about nozzle placement

[ghart999]

I am setting up alky injection into a supercharged Grand Prix so my intake setup is different than all of yours.

My question is about placement of the nozzle. I am placing my nozzle in a 1" spacer between my LS1 TB and M90 blower housing.

Would it be better to have 1) the nozzle flush with the interior wall of the spacer yet spraying perpendicular to the airflow such as

OR; 2) have the nozzle all the way into the airflow (which could disrupt the airflow maybe?) yet be able to spray parallel to the airflow? such as

It comes down to better angled spray but possible airflow interruption or not air flow interruption but less than optimal spray. Thanks all.

The issue is reversion. And in the case of your particular vehicle, the MAF that is part of your throttle body.

If your MAF gets wet... it can get toast... its a very expensive part of your vehicle.

I always err in favor of reliability. The vehicle pictured on my site has had the system installed and running since Jan 04 and over 24000 miles driven.

You can decide whats better. Plus, I dont know how you'll be able to afix the nozzle into the plate without custom machining to it.

Hope this helps.

Actually I have an LS1 TB and LS6 MAF so they are separate units with a 4" long silicon hose between them. Regardless I think the system on your site will work just fine.

I assume you don't think the nozzle all the way in the spacer would cause airflow issues right?

With that setup, I wouldnt use the plate. I'd point the nozzle torwards the TB and negate having to use a solenoid.

One less part.. one less issue.
