With a gtech of course, as to the accuracy of gtech people will have to contact the manufacture if they disagree with the claims of +/- .01

No one is doubting that I am aware of?
Better tyres with a better launch at the hands of a competent driver, should be easy enough?

Something that popped up after that dyno was the fact that my wastegate actuator wasn't functioning correctly. So that dyno is actually only on 3.5psi of boost. That and an overly restrictive exhaust were why the numbers were so low.

All it took was to replace the wastegate actuator and I went to 245hp. With boost control and a half decent tune it then went up to 270hp. Now well beyond that.

But best of luck comparing a turbo to an electric supercharger.

Thanks for clarifing that with your additional (1,000usd?)mods plus the avo stage 1 (4.4k usd)kit with custom(500usd?) tuning(non ots) that you made 245whp. Great hp value for the money i assume?

Edit: as I've stated before, I'm not trying to down play any turbo kit, simply saw your dyno post and thought hey that's pretty close to mines, if that's the avo stage 1 tune, the it's pretty comparable"
I'm sure you'll make lots more hp in the future and dominate the streets, more power to you bro,

I agree. But I'll run the stock car and tires, if nothing else to maybe give a good starting point for those that can only hit high 6s,
Also will record the 1/4et also Just for fun.

Edit; intentions can be lost due to text, but just to clarify, I'm not trying to prove that anyone is wrong, or that their car suck ,or that my D*** is bigger then yours. I'm just trying to legitimize my claims and in the process hope that it would help others. Thank you

Is it bad that I know every turn on that track like the back of my hand just from years of playing forza 1-3?

not to refute anything you said, "But"(from my video gaming background ) Road Atlanta is a pretty fast track with lots of straights, and high speed turns, no way the esc in current config could handle it, I would say the same thing about Road America(also video game experience talking, I have never been on a track, or watch racing). I only live 1.5 hours away, and watching that video makes me excited, and scared all at the same time. My butt puckers watching those last 3 corners.. I have slid, spun off or crashed there so many times in game that imagining my baby going through it makes my heart hurt.. Thanks for the video

On most tracks a car will be in the upper rpm range most of the time.

Case in point

The ESC apparently works on track if you cool the controller properly and add extra batteries. It may even last a full 20 minute session with lots of WOT in the hands of an experienced driver. But the fact is that the boost tapers off greatly and for the majority of of the WOT events on track you will be out of the ESC's efficiency range, which is down low where you get the 5psi and the surge of torque. I understand that every PSI counts and the power increase is there even to redline with 1 to 1.5 PSI. Is it worth it, for a pure track application to have that little boost in the upper RPM ranges? The ESC cost totals in a little over 1/2 the total cost of a full-time supercharger which builds boost/power/torque progressively and you're making 7 to 9 PSI to redline. For me when I consider both and assume the ESC has full support for track applications and the controller overheating issues are resolved, I am inclined to keep saving for full-time FI.

I am NOT trying to start another debate between part-time and full-time FI. I just want to lay out the facts of both for pure track usage. For me I have to consider that I will be using any FI kit on track frequently and I would want the performance benefits to be usable in the upper rpm range instead of the lower. The ESC just doesn't make sense for a track application and I'm not sure any modifications to the system could change that. The voltage would need to be much higher, the compressor spin much faster to get more high-rpm boost, the controller heat management demands increase, the battery capacity increases... which would blow the cost out of proportion to where it no longer makes sense. It's making much better sense to me now that this is a street-only option.

That said, I'll continue to help development of the ESC for track applications in any way I can without actually buying one. Please feel free to reference any of the raw track footage linked in the OP of my build thread for rough (audible) WOT data. At Road Atlanta, my home track, I'm WOT quite a lot through a 1:50 hot lap. I'd say around 60 seconds per lap. I don't have any supplemental data but I know that my oil temps stabilize around 230F on track and my coolant temps hover around 200-210F on track as well. The engine bay gets hot for sure.

Awesome driving! One of my favourite courses in Forza as well Ya Road Atlanta and America are definitely too long of a course for the ESC. Its application in current forum is best suited to auto x or short curvy tracks.

Using the ESC just on the long straights and then relying on Drag reduction in the other sections may work okay.

Im not sure how Nowell is using his ESC when he is on the track.

Took @Robftss for a ride in my frs today after all the exhaust mods were complete. He was blown away and said I scared him a little and he doesn't scare easily lol. After the header and the track pipe install plus the OFT this thing really flies.

Open offer to anyone in the Calgary area that wants to go for a rip just let me know :-)

So, my car is basically stock except for the ESC. I told myself I was only going to get the ESC and then I'd be done with mods. But...

What do you guys think is the best bang-for-buck mod to enhance the ESC? I'm just looking for "the next step", not "this plus this plus ....".

Easily an OpenFlash tablet to make the most use of the ESC.

That's what I told myself, too, at least until the warranty is up in 2 years. But I just got a header. Assuming you already have a tune, that would be the next best bang for buck in terms of performance gains.

Others will argue to do suspension mods before performance. Depends on your overall goals.

here's the 1/4 mile run and 0-60 that i promised earlier,
I'm sure that i could do better but the stock tires just don't grip when going into 2nd gear -_-
0-60 time is at the 14 sec mark at 5.46

the other two videos will be up shortly, just kinda slow uploading

5.46?
14.01?

Nice

Based on what you're doing there, it would appear that I'm losing time by saving my clutch at the change to 2nd gear. I haven't been hitting it hard enough to get much wheelspin at all switching to 2nd... much less a significant amount of wheelspin like you're getting.

Yeah, i got 5.8 0~60 and 14.02 with a passenger.
And with 5.46 0~60 and 14.01 without passenger but i had so much wheel spin on 2nd. The car kinda fished tail a bit.
Here's the other 2 runs just to check for consistency

I'd like to give a shout out to Stormalong for letting me try me his Phantom-equipped FR-S tonight. I'm impressed by the simplicity of the installation. The extra torque is just about right for a daily driver, though I still think the torque to weight ratio is a bit lower than my old (stock) '11 WRX. It might just be that the FR-S, being lighter, is more affected by driving two up. Or it might be that his FR-S has an AT vs my manual BRZ.

I was really impressed impressed by the smoothness of the transition to boost. There is a bit of lag but it's not like a turbo. The lag seems constant regardless of the RPM you start at, unlike a turbo where the lag is much longer at low RPM where there is little exhaust energy. Again, just right for a daily driver. I really like the stealthiness of this thing. Good power whenever you need it, but no downside other than a slight weight increase and the modest cost.

Now I have some decisions to make...
