Testing Our New Vortech Cold Air Intake @ Pure Automotive Performance! Dyno's Inside!
 

If you've ever worked on a Vortech kit on your twin, you know what a pain the Vortech air box can be. It's a nice box, but it's big and it's hard to remove and install. It also gets in the way if you have an oil cooler, the lines can rub the box causing a potentially bad situation.

We decided to see what would happen if we remove the box and go behind the bumper to get some of that slightly fresher, slightly cooler air to feed the beast.

Here's the setup:

Stock Injectors and Pump
Stock Vortech Pulley
Agency Power Equal Length Header
Perrin Over Pipe
Invidia Resonated Front Pipe
Perrin 3" Catback

Nice! Do you have the deltas between this and the Vortech airbox? You have a few other mods on that car that I see adding to your final dyno and it's not clear to me what gains are attributed to the cold air intake. Oh, and does this have a connection for the PCV or are you venting to atmosphere?

This is where the car was at before when it had the stock vortech airbox and a borla uel.

This.

Is it colder air, less restrictive intake, or a combination of both?

Realistically, would we need a tune to take advantage of this or is this a "bolt on and go" mod that will realize gains without a dyno tune?

Nice results, I wonder what a smaller pulley will net? Also E85 is going to be very strong with this set up.

A tune update was needed. A simple datalog update took care of this. The first dyno ran 287Whp prior to the tune update but was a little unsafe lean.

My next step is injectors and to get the map setup for my flex fuel :thumbup:

@pureautomotive ya beat me to it! I still may make my own. with my stock vortech air box Dynosty mentioned to me that at 14 psi he felt like it was needing more air

Unfortunately due to a broken header, I wasn't able to do a straight up comparison because we switched headers. I have a couple of local customers with Vortech setups that I will be doing baseline comparisons with. The weather is a little bit cooler, the header is EL instead of UEL, so there is a lot at play with this one. However, I don't think 15 degrees and an AP header should account fo the entire 30hp that it gained. I'm excited to do a true back to back comparo.

I just blocked off the port for the vent hose on the Crawford AOS. Both heads are still vented to the AOS.

I didnt post a comparison of his last time on the dyno because I feel like there are so many factors at play that it's not an honest comparison, I don't want to mislead people with a huge gain.

The next one I do will be a back to back comparison without any modifications. I do believe that a slight tweak will need to be made to the tune.

I don't think most of us would be looking for any significant gains, personally the ability to clear the oil cooler more cleanly give more space for heat dissipation ease of work along with the possibility of having lower IATs would be nice.

Want to see where this goes.

Are you running the snorkle behind the bumper as well?
I was toying witht he idea of making the box opening larger, but I didn't think that the vortech airbox was a restriction....

That's my thought as well, I don't like the big air box. It it makes some power, that's a great bonus.

Still have the snorkel the blower has a 3.5 inch opening. I just think the volume of air it can pull in is not enough to feed my 13+psi

I would be in for this assuming I could still run the breather tube into intake and the tubing and everything was all black no absurd colors or chrome. The nice thing about the Vortech box is the oem look.

Regardless thanks for working on it.
