For those who have doubt in the Vortech kit please read.
 

First off let me give those of you a short summary of my kit and mods. The only mods I have beside the supercharger is PERRIN catback non-resonated, non-catted front pipe, and over pipe I have their oil cooler and air to oil separator. I received my kit in December of last year. I had PERRIN’S so for the first couple of months had a lot of different maps that mad great power and was happy with. But it just wasn’t enough being at such high altitude I didn’t see the same numbers a lot of you are with their tune. Here’s the dyno chart just for a refresher.

After running their tune I decide to go in my own direction with this kit. In order to run E-85 I went with Visconti’s 500cc fuel injectors and fuel pump. Also had a smaller pulley ship to me from Vortech. The smaller pulley didn’t make very much boost from the old one maybe .5 a lb. but the E-85 made good power with the kit. I thought this was it, didn’t think there was going to be anymore power come from this kit with out a compressor upgrade and some internal work to the engine.

Couple weeks later I received a call from Vortech asking me if I would like to send my blower back to get a compressor upgrade. Took me about an hour to have the blower off and at the ups store. Got the compressor back and reinstalled with a smaller pulley then what comes with the upgrade. Because of my high altitude to make more boost I went with a lower rev limit and a smaller pulley. After wait a long three to four week for the tuner to have some free time to get my car back on the dyno.

Coming into this I was expecting to be around 290-300hp maybe 200-210tq. Went to do the first pull and the car went lean at about 5500 rpms. Wish I had got these charts printed. But at 5500 the car made 250hp and 180tq. It took awhile to get the AFR right after a lot of tuning he finally got it right where we wanted it I can say I am very impressed with what Vortech. Once again it’s like a whole new car. The car made 365hp and 261tq with the rev limit being set at 7450rpms. It made 12.5 lb of boost. Now this is what I was looking for. I found myself asking the tuner if his dyno was broke. He reassured me it wasn’t and that it reads low compared to a lot of other dynos. After dialing the tune for about another hour it was good to go.

I planed on towing the car home but after see these numbers I just had to drive it home. Just form the drive home the car is amazing. You have power down low no need to down shift to pass. From 1000 to 5000 you can feel the torque your heads almost all the way back in the seat. But where the real power is, is from 4500 to redline WOW. Wish I were better at describing all this for those of you who don’t believe in this kit or have any doubt about it. It doesn’t give you the head jerking motion that a turbo do. It a nice smooth felling that happens very quickly. Next purchase is going to have to be tiers the tiers break loose in first second third and sometime four now. Hoping to get a couple in the car videos for you guys today. Hope this helps some of you out like I said I cant describe how amazing this kit is.
Big Thanks to Vortech, And The Boost Creep Ltd. for the tune.

Any numbers without e85?!

Awesome results man! :thumbsup:

Not with the new compressor. The most I made on 91 was like 220hp and 160 tq I think but that was with the old compressor

Awesome thread, thanks for sharing. I want to ask, are you still int he stock fuel pump? Those are very good numbers. Would you happen to have an AFR curve and boost curve?

Congratulations on that beast!

Okay I'm on the new compressor right now pushing around 250whp. You think the smaller pulley will make a difference with 93 octane?

Can you post a tally of the parts your ordered with the price you paid? I'd like to see how much it cost you to get that horsepower.

Isn't it just upgraded fuel pump/injectors and small pulley?

You need to get the PL or nameless header on this beast now! Amazing numbers!

Also go get redynoed at sea level for fun!

E85+Vortech=:confused0068:

Congrats man! I was already sold on this kit, but now you surprised me! Enjoy your new toy!

Yeah, 365 at altitude is amazing...even more powwuhhhh at sea level.

So you throw cams, a good header *nameless/PL*, and any headwork/valvetrain if its worth while and 400whp?

Not if the numbers are properly SAE corrected.

Wow.

They a corrected but you will see more power because you'll have more boost at sea leave. I see it being 390- 400 at sea level.

No I have the upgrade fuel pump John offers I don't remember what it is off the top of my head.

Congratulations on your new powah!!! Very glad to hear that you are happy with your Vortech system, and thank you for the support.

I hadn't thought of that. I am used to turbos where the boost is adjustable. :scared0012:

@ngabdala

Get some numbers on 93! :)

I'm sure I am not the only one with this stance on the matter, but my issue with the supercharger option is the lack of torque, and the stupid amount of boost you have to run on them to make them comparable to most of the turbo applications out there already.

12psi on the stock motor isn't the greatest idea, and overall HP isn't what I'm looking for - it is the TORQUE that I want. Turbo kits like AVO's 5psi offering on standard 91 octane (most of us have 92 around) and zero fuel system mods puts out 230whp/197tq - which is more torque and close to your HP figure after you converted to e85, new injectors, new fuel pump, and a smaller pulley. FA20Club's kit nets even more on 5psi. 286whp/210tq.


The bottom line is there are more cost effective, scalable, and more efficient options out there. Supercharger on this motor doesn't appear to be worth the money.

Just to confirm - the only difference in mods between the last two plots are the upgraded compressor and a smaller pulley? That's a lot more power than I expected to be gained from just that. I guess the corn juice is really making this thing open up.

And shit, I just noticed this is on a heartbreaker?

Agreed - but can we not turn every Supercharger dyno thread into a Turbo vs. Supercharger discussion? There are plenty of people who have valid reasons for considering a Supercharger over a Turbo, and nowhere in this thread was the OP trying to say one was better than the other.

So then dont buy a supercharger? Spend your money the way you want. OP obviously liked this route.

Nice results!:bow:

I'd love to see those, or even just 300whp on 91 w/ 12 psi and the smaller pulley. That would be epic.


All your base are belong to me.

I wouldn't necessarily call an old software Dyno Dynamics a heartbreaker dyno. I would also liked to have seen these runs done in Shootout mode.

With a thread title specifically targeted to those to doubt the Vortech kit, I am simply stating my reason to doubt, not saying one is better than the other, but rather (as I stated in my first sentence) this is MY issue with it. Good day to you, sir.

Understood - but doubt doesn't only come in a Turbo vs. Supercharger format. Either way, I hear what you're saying. :w00t:

...and yet there are multiple people here on FT86Club that are saying the Vortech kit pulls harder and feels stronger than multiple other turbo 86's they have driven. Hmmm...

Willing to bet you won't be getting a turbo or a supercharger :sigh:

As a mechanical engineer, hard to comprehend how do numbers lie...

Bet you're wrong. :bonk:

lets not make this a sc vs tc discussion

:thanks:

^this

People can be swayed in their perception through emotion, sound, even that big breakfast burrito they ate earlier in the morning.

Dynos, while not the be all end all, put down cold hard unbiased numbers.

That's what I thought to. But it's true I have to say it pulls harder. I got to ride in a frs with the P&l kit. It pulls harder then my buddy's Sti that made almost 75 lb tq then mine.

I love the output. It needs E85 to get there, but this is still on stock headers. No ECU trickery to pass emissions testing. The smooth delivery is good on the drivetrain and clutch.

I'd love to see what the output was at on pump 91, just for kicks. But I love seeing the potential is there.

Perception is part of what makes this car fun! It feels fast, because of the low limits of the tires. It's got short gearing, and the intake sound in the cabin makes this little car feel fast. I loved racing on the track. There's little doubt my previous projects were much faster, but the BRZ feels amazing on the track. It feels quick.

How many of us are going to be racing competitively? Having a car that feels fast, but isn't, will reduce speeding tickets. I know. The majority of us will take perception over reality any day. Perception is more fun anyway. :respekt:

Actually, I saw the ECU reporting the O2 System readiness as a steady "Incomplete" even after 700 miles. This would fail emissions testing.

Please elaborate. This car doesn't say "ready", even with factory cat in place?
