Yes it is.
That 300whp run is Jeff having fun, and likely the systems limits, that may be a better display of what can be done, not what we should all be doing. My aim is just a hair south of that number for safety sake.
Indeed, he is having alot of fun and so am I. I can share a little more today:
Since the
cat is outta the bag, I will say i have been testing the
10psi version of this kit of late, and the 3.48 pulley supplied is just the icing on the cake at its 243-250whp.
Its good, its very good, its the poon before the tang. The donut, not the jelly. It just keeps getting better for me so I am sorry if I am bubbling over with enthusiasm. the 10 psi setup crosses the line for me. ymmv. it gets me to PAST 'enough'.
I think 99% of even the most enthusiastic FRS/BRZ drivers will find what they came for , here at 10psi.
I plan to baseline again at the dyno what the 10psi got me before I add a future wastegate, and EBC to give me the most control on how far I want to be able to push it, and feel safe. I will explore 11 psi and maybe beyond, but you wont see my car running more than 12psi as a final solution.
Once you go to the 3.33" pulley, you're at 10psi. Does it feel better than 9?It makes my car officially scary.So yeah, call me biased, call me whatever, the boost feels awesome, Perrins tune is friggin awesome to bury my foot into
This the real deal.
Guys, while I would be the last person to ever tell you to not buy the Vortech kit direct from Vortech, I do want to give credit where it is due- the guys at Vortech put together a stellar 9-13.5psi kit just fine its the bees knees, the bulls balls, it makes me get in trouble with the wife who now prefers I slow down, and she is right, the car gets fast, fast!
BUT....
I would say unless you absolutely need the Vortech/Carb tune, the Perrin tune is where its at. Hell yeah.
the tune I am running from Perrin is by the seat of my pants faster than the tune file that I got from Vortech, same pulley. The file I got from vortech didnt 'like' the 3.33. Jeffs tune file *loves* it
I have not flashed back to the Vortech tune. Not sure if I will, tho that is the version the wife will likely run on her DD car @ 250whp/3.48". I'm running thsi so far without a wastegate, but there are some safety concerns checks on Jeff's side that i am still waiting to hear back on.
For getting silly and sideways at the track, holy cow guys, I want to take my hat off to Perrin, for making the cake, better. Its like he added the 'special ingredients'. It is where my rubber officially exceeds its limits with the extra 1psi, you wouldnt think it matters, but it does. I want to make sure I convey that 'zone' for this cars chassis, anything over 260whp is spooge territory.
So as of today they released 9psi kit boost will get ya right about 250 whp. I'm getting 243, and I chalk it off to gas and altitude, variance, etc, I'm confident I could get a 'best run' to get me another 5-6 horsies.
My butt dyno says 10psi of boost with a Perrin tune must be feeling like almost 255- prolly closer to 260hp at the wheels, knowing what 240-243 feels like. Could 11psi be 265-270? 12psi 275-280? 13psi 290? and the 14psi limit is at 300whp? yes, I tend to think so. Hello smaller pulley(s)
Today 10, one day 11psi, then 12. Stay tuned. Dynos next week of 10psi @ 1500 feet in PHX.

I see the motor tolerating more boost below this RPM, over this RPM, adding too much air too soon hurts, not helps, and while this may change in the future as of today, to run more boost that i am running now you need a wastergate, so for Jeff to be pushing 11,12,13,14 psi and making that king of power, he must be blowing off boost at carefully selected point(s) to make the motor do its thing. I find myself shifting around 7000, while it keeps pulling, yes TQ peak has passed, so its time to shift and go back for that TQ peak. I like how it works, you gotta drive it to get a good grip on what it is.
