*PHASTEK* Perrin Tuned Vortech Supercharger Install Thread (3 Vehicles, 3 Kits)

[PhastekSport]

First run results with the smaller pulley.

[Opposed]

Ok, that's looking more like it. Im curious to hear how the car feels now...

[2forme]

How many PSI? and holy timing pulling batman!!! That is not a happy ECU. That is even with smoothing set to 3.

[PhastekSport]

10psi. The data has been sent to Perrin as requested, but this is the first map which was sent to us.

Not much timing was pulled according to the data I captured. Here is smoothing @ 0 from a previous dyno I posted. The lower numbers are w/ header back exhaust and no tune vs stock pulley.


7psi below

[Coheed]

10psi and not 250whp... is something wrong? I want to see you guys dial this in, because I'm really considering this kit. But I'll be honest, I'm a bit sad that it isn't performing better on the output side of things.

I'm sure the car is killer on the autoX course too. But I'm really wanting to see someone break 300whp.

The only other way I see a car being legal is using a rear mount turbo. This is important to me to keep the car street legal. I'm really glad you guys are taking the time to play with the setup and post your results. I'm looking forward to seeing your future endeavors.

That cant be at 10 psi.

[PhastekSport]

The last dyno posted was at 7 psi peak. The one we were talking about earlier is 10psi.

This image is from Perrin's blog. They have updated it recently.

I bet it is. Seems about right. Even Gems car took something "super secret" and 8.5 PSI to get 240whp.

Definitely needs some tuning up top, though.

Visconti had already posted somewhere that the 10psi kit doesn't make much more than the 7psi kit on pump gas. From the look of that curve, it's pulling something up top because ECU doesn't like what it's seeing. Look at the smoothness of the base dynos in comparison.

Well something is going on with that jaggedness. Perhaps the MAF isn't calibrated correctly in the tune? What are the MAF readouts up high? How much is "not much" timing? I would consider 5 degrees to be a bit much on a high CR motor like this. Also are you using a 3 bar map sensor? I think the stock one is nearing or surpassing it's limits at 10psi of positive pressure.

This is a realistic result, power-wise. Good job Phastek!

[johnnie]

So its +70 hp over stock at 10psi without adjustments. That sounds pretty good.

I'm just putting it on the dyno and posting results, but thanks!

The other guys in the shop are primarily focused on the bread and butter.... domestic vehicles... So the ecommerce guy (me) pushes the 86 stuff. EDIT: Between 7200-7600 RPMs -0.7°CA Knock correction.

I did notice at the high end where the peak boost is that the graphs were getting rough and it was pulling timing. Right now I don't have the data on me (edited above), and soon I'll be hunting down the super secret stuff to keep this thread alive. Since I have 3 vehicles in the area that can be tweaked, we get to show a lot of results.

Victor will be getting his Borla UEL header this weekend as well.

The Perrin kit comes with a 2.5 BAR map sensor btw.

Thanks Chris! You guys are doing a great job with this thread. I'm hoping Perrin sends you some corrected maps and you get to post more results!

For everyone else, Phastek is ~115ft above sea level. So these results are, for all intents and purposes, at sea level.

[PhastekSport]

Had to get this done so I could data log and get results back to Perrin. Thanks Jeff for working with me on the smaller pulley. As always more to come.

[reyruiz191]

Good looking numbers and thanks for the constant updates. You guys may have just made my choice of what kit to go with. I may just pull the trigger on the vortech kit here in the next couple of weeks.

[PhastekSport]

They made their announcement. In for 3!
