Jesus Christ somebody hurry up and grenade up their engine!

…What? We’re all thinking it.

Or better yet, cram 10 pounds of boost into it and demonstrate that it’s just fine!

Yeah yeah, then try for 15 psi.

 

[Xwolfe]

I plan on supercharging, specifically waiting on Jackson Racing. Need to save a bit but hopefully sometime in 2024, or late 2023 at the earliest.

Forced induction on an engine that ready has a 12 to 1 compression ratio sure seems like a really bad idea. Unless of course you are entertained by unscheduled rapid disassembly of your engine.

I was finally able to install the tune on my car yesterday. I took it out for a few hours to see how it felt after relearning. The biggest improvement is throttle mapping. The stock calibration is a bit bizarre, especially driving the car with a linear curve now. The torque dip is almost complete gone as well, and with the bit of extra power, the car feels much quicker even if it isn't. Power builds linearly and it doesn't stumble anywhere anymore, giving a strong consistent pull feeling. A side benefit is that it is also much easier to drive at low speeds. Exhaust sound is much better as well. The tune gave it an edge that really rounds out the experience.

The engine is starting to feel & sound like a purpose built performance motor now, rather than a modified econobox powerplant which had some considerable shortcomings. That said, the power change isn't night and day. In general, the torque is less noticeable than the recalibration and power which might be disappointing for some given the cost. Regardless, I still think it is worth it.

Car Details: '22 GR86 manual, Delicious Tuned via EcuTek ProECU, Charcoal filter delete, GR Airfilter (KN), Corsa catback, and a winter wheel setup that weighs 25 lbs total less than stock. Plus a few non-power-train mods; camber bolts, clutch spring, door stabilizers. I'm just under a mile above sea level running 91 octane.

 

[TRU-BOOST]

Can you post up the dyno results?

I'm also interested to see in a couple weeks how your fuel economy is. If it's not a major change maybe I'll see what I can do once the snow goes away

 

[Wayward67]

My fuel economy was slightly better with my gen 1 but those were a bit rich.

I'm sure the cost of the tune /parts will be the primary expense with NA

That is great to hear if all you have is a cat back exhaust. Just hearing about how it builds power now has my attention on doing this. I wonder how the daily drive will feel when you get a header on there too in the future?

Great to hear your review so far. As for the question regarding fuel economy, it should stay equivalent to stock as we minimized the changes in the cruising areas.

Spent a lot of time in the car this weekend getting the ignition timing advance multiplier to 1. I did a handful of pulls this morning and ran them through vDyno. I did 5 3rd gear pulls in total, throwing out the high and low outliers (242 and 202 corrected whp respectively). I've worked with vDynos a lot in the past on other platforms and when done correctly, they're very useful for directional use and can be quite accurate. That said, I haven't spent much time on the roads here. They appear to be pretty flat but I'd want to measure them before putting much stock into these results.

Regardless, the three remaining vDynos linked below were taken during the same drive but on three different roads with a few minutes in between each one. I'm guessing the peak torque spike on the blue line was a dip in the road. I also want to mention it was very cool (30F) this morning but also quite humid (70%), and for reference, the corrected vDyno was showing 208 whp yesterday before the ignition timing advance multiplier settled.

Adjusted for Elevation (225 whp, 163 lb-ft wtq) (I used the SAE option to adjust barometric pressure rather than using a custom correction factor. However, regardless of method, this technically exceeds the SAE's thresholds for corrections but everyone up here loves to do it anyway so what the hell)
Uncorrected (201 whp, 163 lb-ft wtq)

Edit: I reset my trip just after tuning, and again this morning. I put roughly 300 miles on the car this weekend just blasting around. The deltas after the first reset and after my most recent drive are within the noise. Feels safe to say there won't be a significant hit to fuel economy.

I have absolutely no experience with dynos but what was the reasoning behind doing 3rd gear pulls? From reading other posts, I thought that the best gear to use was the gear with a 1:1 ratio, which is think is 5th for MT.

 

[Wayward67]

Probably space, and ticket size if noticed

25 mph over the speed limit is felony speeding

 

[moldy_lunchbox]

Stock - 149.07 KW (199.9whp)
Tuned - 176.44 KW (236.6whp)

Stock - 237.60 Nm (175.24 ft-lbs)
Tuned 277.43 Nm (204.43 ft-lbs)

I'm just the messenger. Don't come to me with questions about the results. The header is a prototype for the 2nd gens from SME.

 

[Timster]

That same SME el header is used in the motive BRZ, without a tune, the headers made a decent gain on their own and no codes were thrown either.

 

[TRU-BOOST]

Quite a bit better gains than what any of the American tuners have been able to pull off. I would blame it on fuel quality, but once we are talking about E85 that goes out the window.

 

[Timster]

Australian 98oct petrol is about the same as the American 93oct, or slightly worse. The headers I think are a larger diameter than the aftermarket stuff made for Gen 1 cars.

 

[Wayward67]

There was a decent difference btw let's say ace headers and borla headers with the first gen.

35hp would be noticeable for sure

 

[TRU-BOOST]

Its possible it is the header design or just more aggressive tuning. The OTL header that Kevin Vo tested was supposed to be "the best header design possible" and that made almost 10HP less. Obviously there are variables from car to car and dyno to dyno. What makes it more significant to me is that the Australian car actually started off with a lower baseline dyno and ended up with a higher header\tune dyno result.
