Quad nozzles anyone?

[Razor]

Blower on 5.3 needed some more cooling than normal.

Nice! I see your moving more to the Ford guys?? JK... Good work.

 

[GNBRETT]

nice, so where the TR quad kit...

You guys are slowly working up to that Top Alcohol Passenger Car class.

Razor i could probably benefit form a 3rd nozzle on mine. Approaching 140mph trap speed. Have 3.5 bar sensor so im not getting max flow as early as a 3 bar. Let me know your thoughts.

what size nozzles are in that intake razor?

Look at your IAT. If its slammed low.. leave it alone.

On the 5.3 it used 4 M3's.

The Cobra used 4 M5's.

Any luck with the Cobras? Everyone on the Cobra sites says that Alky doesn't work on those cars, no cooling effect. That set-up you posted looks great.

Anyone seeing this would say otherwise.

Typically on the roots stuff we do it pre TB and its for additional octane. When your on pump gas.. anything you do to bump up the octane is beneficial.

It sure is a pain to do the install since the intake has to come off, but you will get results

There are many ways to achieve results, these are cases where things needed to get a teeny but more complicated.

Thats alot of brass

Its only 15 degrees or less above ambient up top:biggrin:

Hey Julio,

It's not a 2003 Cobra lower intake. It's on my 2008 Shelby GT500..... and it works great!

To add to Julio's answer, the reason why Cobra's have limited success at best is because the roots / twin screw type blowers absorb the cooling effect of the alky and IAT2 temps remain approximately the same as using no alky.

I originally had my PAC on my TPI IROC-Z with an ProCharger. This was a simple single nozzle setup and worked well. I then nixed the ProCharger and went with a twin-turbo setup but ended up selling the car before even making one pass with it. I then installed the PAC on my Whippled '05 Mustang GT (pre-TB) and saw no cooling effect. Once I had an opportunity to pull the lower intake off my '08 GT500, I realized how "convoluted" the air stream is and it became apparent that even a twin-nozzle setup after the intercooler would not have optimum results. So I decided to think out of the box and go with four nozzles for a "fogging" effect.

The air temp on my IROC-Z with a centrifugal blower and a single nozzle would drop below ambient. My four-nozzle setup does not have this effect, however the temperature drop is significant. My IAT2 temps are now about ten degrees above ambient with 14-psig boost. Pre-intercooler air temps are well over 200 degrees. I have gauges to prove this. The OEM roots style blower is infamous for producing massive amounts of heat. So I'd say my design works well.....

Willie,
Welcome aboard. Thanks for the correction on the motor

Good to hear. Will try this on a buddies 03 Cobra sometime soon.

This is great info and it can be proven. You figured out how to apply the alky so it worked.
