First post,
Long story short my car was the second r&d car for Vortech Engineering. I've had it tuned for about a month now, had the car total about 9 months and am absolutely loving it. Car made 272/212 on 4lbs and kept the same exact power curve (still stock headers.)
I came here to ask questions about those tuned on ecutek so far (na or boosted) what parameters are you displaying on the ecu connect app? My current parameters are knock correction (retard amount ak), manifold pressure, coolant/oil temp, iat, target/actual afr, and probably something else I'm forgetting.

(For those interested, recently jailbroke an old phone and have been using that to display ecu connect app to carplay, wasn't too difficult at all)

I don’t monitor any parameters with my tune but it’s so conservative there isn’t really a need. I didn’t come here to say that though. I came to highjack your post and ask if you have any insider info on when they will go public with that kit?

 

It's been about two month's since I last spoke with one of vortech's reps but from what I recall between my car and the first car, the r&d is done and they said kits should be expected by the end of the year, maybe a bit after. But I'd take that with a grain of salt.

 

Why are they messing around with 4psi? I hope they plan to do more testing than that. Glad to see they are doing something at least.

 

Engine blows at 5psi? Lol I hope not. All that work for just 4psi is sad.

 

Oh hey, I have the kit off the 1st development car.

Any insight into what changed between mine and yours?

From what I know the kit you have was done a 22 brz, assuming you bought it off facebook marketplace; they just wanted to confirm fitment for the gr86. I don't think anything changed

 

I would presume there are going to be staged upgrades. Non intercooled 4 psi sounds like a likely stage 1 kit. Stage 2 intercooled, 8-10 psi and (if the engine can handle it) pushing 350+ seems possible.

 

It's a full intercooled kit, mostly just a copy paste from the first gen cars. Just had to do a bit of rerouting

Since I definitely derailed your thread I can at least tell you that on my golf r I use the Cobb AP to monitor knock retard and egt if I’m going to a rip in the twisties. Other than that I just keep oil temp on the center screen.

 

It's probably running at 4psi, to get past CARB.

 

Last I heard their plan was to have two kits, one being carb legal and the other not. Don't quote me on that though, they said the had a hard enough time getting the first gen to pass. Second gen kit uses the same supercharger system as the first gens (has carb sticker on it) but hasn't done any testing to pass carb specs yet.

 

Stock injectors? Maybe running out of fuel with the stock injectors?

 

Quote from my tuner "the fa24 moves a lot more air than the fa20, so it makes sense it would see less boost. The air can't backup/build pressure if it's being sucked up just as fast as it's being produced." Also Ecutek is still in beta, especially for fi cars so there were issues on dyno day (stock map sensor is at the limit, can't be disabled/bypassed yet, 2.5 bar map sensor created low voltage issue at idle (even when disabled still occurs)

I mean its 0.4L bigger so it doesnt displace that much more air. If they set up the blower the same way they would for a 2.0 car it would make sense that it would fill the larger engine with less boost, but not that much less, 1 maybe 2 psi max.

Nah. An NA car running E85 will use more injector than a boosted car on premium with that small amount of boost. There should be plenty of injector left.

Thats what i thought, but just trying to think of why. lol.

 

I would think there is more to it then raw displacement. Small flow improvements in the head, valves, headers, intake etc etc are probably factors as well.


Too bad on the multi stage kit. I'd prefer a supercharger system and 280-300whp would be perfect for me.

 

Engine displacement is literally the amount of air the engine moves in 1 revolution. Obviously that is a volumetric calculation based on bore and stroke so it does not account for things like compression ratio or flow efficiency. So realistically you see the most variance on NA cars where minor flow improvements go a long way. Once boost comes into play, that air is getting jammed in there whether it likes it or not, so flow improvements are much less meaningful. Thats when you start looking into better exhaust. This is a well established path on 1st gen cars. IMO other than the displacement, there isnt much else changed.

 

I got a ride on the first BRZ owners cars (the one who sold it). The car definitely felt slower than my tuned stage 1 delicious tuning e85 tune. Just saying….I was very puzzled why. He said it was just on a tune to get em to the tuner. I’m sure same superchargers from last gen should be up in the low 300s to the wheels.

 

Am I the only one that noticed an ECUTEK tuning frenzy 6 months ago or so, and now radio silence?

 

My guess is because there was a bit of problems with missing files initially. That and the Race Rom features are STILL not available remotely, only through a dyno tune. IMO its not worth the cost for a dyno tune on these cars if they are NA. There is nothing that can be seen on a dyno that cant be seen data logging other than power numbers, which are the least important part of a tune.

 

Keep in mind that PSI and airflow are completely different items. You can have 2 identical cars running, for example, 10 psi. However if one of them is capable of flowing more air (ie bigger, more efficient turbo) at the same pressure that car will make more power. At the end of the day pressure really doesn't matter, flow does.

 

I'd assume most of the restrictions come from the plastic intake

What are the differences between the gen 2 intake manifold and the gen 1 red intake manifold? Is there a difference in the amount of air that they can flow?

 

Someone already swapped them...IIRC, more torque and less power.

 

ah do you have a link or something with a dyno sheet?

 

With FI I doubt the manifold makes any difference at all. Exhaust mods will help the most.

 

If I've read correctly with no other modifications we have "Car made 272/212 on 4lbs and kept the same exact power curve (still stock headers.)" and that's not nothing.

I keep flirting with FI and it's turbine whine but only for spirited sports driving enjoyments. Lightening my BRZ and the 4:3 differential has gone a long way for me so I don't need 300hp!

I'm really really glad you and other higher testosterone and technically driven members keep up the investigation and work.
$8k is fine by me but I don't want a bunch of additional engine mods or louder except for turbo exhausted sound.
Cheer!!!

 

High testosterone yes, mechanical inclination not so much. I don't mind doing 100% of the work on this car, but the whole thing is a learning process. I'm going in blind with high hopes and low expectations.

 

All this really has me bummed, at the very least I won't get/have to think about it for the next 6 months so maybe some real solutions actually start coming out by the time I get back into the swing. Really hoping that we won't have to stay full Nascar spec for much longer either by that time. I'm really looking forward to having a ton of fun in the car, stock and beyond, but the option and something to work towards would be a lot more interesting and fun imo

 

Yeah if the transmission didn't pop at 400hp then a turbo might be the best option for now. I am still on the twin scroll SC camp for this car but.....

 

Really glad there will be a kit to boost the power output. I'm not sure whether I'll buy one or not. I will probably wait and see how the cars do over time with the additional power. I might buy about the time my warranty runs out.

I bet an extra 50 HP at the wheels would feel great on our cars!
