Questions and Discussion on Vortech Supercharging Systems

I was checking out the Perrin Overpipe, Frontpipe, midpipe, and catback system and was thinking about combining that with the Borla UEL headers.

I did see a post about the Visconti tuning providing enough fuel for headers so I was wondering how the vortech tuning held up

The Vortech tune is designed for a stock car. It won't be optimized for many other flow mods you have.

I have that setup and Perrin's tune works great with it.

Hi, couple questions:

Firstly, at the moment I'm looking at purchasing the kit through Perrin but I am wondering if Vortech have any suppliers in Australia that I could get it through instead as shipping is a killer?

Secondly, how many people are running the 13 psi pulley reliably?
For starters I only run my car on 98 octane fuel as its readily available here so that would increase the reliability straight away over only running 91-93 correct?
Just wondering if what the general opinion is on how much boost these engines can run reliably on 98 octane fuel?

Much appreciated

Is it the headers that's the primary reason it needs an alternate tune?
If I left stock headers and kept the rest of the Perrin pipes would it be fine with the Vortech tune?

To answer your question directly, yes I think it would be fine, just as if you got a headerback exhaust on the stock tune. You may lose power but I doubt it would break anything.

BUT..

I would go with an aftermarket tuner unless you planned on keeping the stock exhaust. In fact I would recommend an aftermarket tuner in general, Vortech's tunes are 100% safe and reliable but leave plenty of power on the table. If you are getting a headerback and looking at headers for more power, it seems like a no brainer to get a tune to unlock that power.

Your 98 is the equivalent of our 93.

It's mostly for the noise haha, the SC is for the power.

Just purchase your kit through perrin. I am sure they have a tune that will compensate. Also a lot of the tuners that sell the Vortech kit send you a base map, and then request data logs to calibrate based off of your modifications, and other misc variables.

This is of course unless you already purchased from vortech direct. The price is nearly identical between most of the vendors/tuners and they all use the same ecu system, just a different rom file.

@SillySaxon Also headers+tune is the primary tool to completely eliminate the torque dip. It cannot be understated how big of a difference in driving pleasure that made, even after I already had the supercharger installed which reduced the dip a lot.

That makes sense. What headers would you suggest? The Borla UEL ones sound too ricey for my taste and i didn't notice any from Perrin

JDL and Revworks both have very good UEL headers right now I think. That is really a matter of personal preference brother, you have to listen to them and decide what is good for you.

Nameless has been working on a EL header for a while now that I am pretty excited about, but I am not expecting them to release it for a while yet.

Search around the Engine section, there are a ton of threads about headers with video clips. Just remember, nothing beats listening to it in person!

Nameless... i was so excited for that. They were updating all the time etc and them BOOM gone. I hope they actually release it. The fact that none of their staff will post anything and only members are saying "i heard that its coming soon!" scares me. It was looking pretty good on early dynos! I was going to do that + e85 originally but eventually gave up and said FUCK it and went with a supercharger (that never showed up... LOL). Maybe by the time my credit card company finishes my dispute it will release!

Really? More info?

And yeah, any news on people running 13 psi daily?

In most countries, including Australia and all of those in Europe, the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI, and often written on pumps as (R+M)/2). It may also sometimes be called the Pump Octane Number (PON).
