#openflash #header #installation
It's nice the header helped out the torque dip. Should come in handy when autocrossing and in a slower 2nd gear corner. Thanks for keeping the series moving along!
The pull out of low RPM is pretty darn surprising now, every gear feels the same with the flat torque curve.
As soon as I have my own garage with a lift, this will all come in really handy
I did uel headers on an Sti with one jack you can do it too
Thanks so much for making these videos. Great presentation and exactly the content I was looking for in deciding what to do with my BRZ.
Glad it was helpful!
Btw. When running on e85, i think you need to change your engine oil more frequently. Anyway great numbers bro. Im also an OFT e85 user on 13 brz. The engine revs more freely on e85. Its like it was made for it.
This motor comes ALIVE with E85, it's depressing when I have to run pump gas. I've been running E85 in my other track car for years and you absolutely need to change the oil more frequently. I usually cut the factory recommended intervals in half for track cars, for a street car reducing intervals by 30% should be enough.
206 to the wheels would mean 220 to the engine.. that's pretty good without an aftermarket front pipe..get a front pipe!
The biggest reason I won't is noise. We have really strict noise regulations at local autocross. I'm really comfortable with how the car sounds and don't want to mess with it. I'm also not convinced it's worth that much power.
i think its more like 240 crack
@@TheDriversPerspective would recommend the hks front pipe... It's come cateed and with a resinter
@@broshido2745 most of have 170hp to the WHEELS. They didn't lie or there would be huge lawsuits for false advertising.
Travis kingsley Nope, hp numbers lies have been around for ages, take the R32-R34 skylines, they advertised it as 280hp when they actually had ~330hp and there are many more examples
Subbed! Very informative and I own a 2013 frs. Borla uel headers, invidia n1 catback, waiting on my catless fp, and then will ship the rest of my exhaust parts to Arizona due to CA emissions regulations not allowing me to purchase parts and have them ship to CA.
Dyno Dynamics is a very honest dyno too.
Nice video! Useful information on headers and tunes. Thanks! Also, I recognize that t-shirt! Hope your re-tirement plan is working out.
Thanks! Re-tirement has been great, wife approved even!
Good Sound but I am disappointed with lack of torque dip being filled. Solid UEL headers normally do this, but you are running E85. I am guessing on 91/93 the difference in the dip might have been bigger.
The difference is much less pronounced with the 4.0 tune with and without the header running E85. It is a HUGE difference from the stock header, E85 and the 3.02 tune.
Nice video man. I like your style
Thanks!
Great video! I want to purchase a open flash header. Unfortunately, open flash hasn’t produced them for years. Is yours for sale?🤞
Any idea where to find one?
Thanks,
Chris
Why the openflash header vs tomei or JDL? Seems like the ofh is the best bang for the buck but the tomei and JDLs offer slightly more "performance" according to the dynos I've seen posted.
I was working with OpenFlash to help test some things with the 2017+ motor and they had a OFH v3 available for me to use for the right price. JDL and Tomei make great stuff, I do not think the extra $$$ for an ACE header is really worth it. Three times the cost for not much of a gain.
Thanks. I have been looking at that header for some time.
It is a great header for the money, 10 lbs lighter than stock too.
10 lbs off the front wheels!
I can't wait to get the AP Racing Sprint BBK installed, 20 more pounds off the nose. With a light battery I bet I can get the total to 50lbs!
Is there an BBK that fits under the stock rims? I have not found one.
Not that I am aware of yet, I'll keep my eyes open for one.
206hp!? Did you get the cartoon or did you put it on E85 that seems like a big jump for just headers
E85 was required to hit this number, noted on the dyno sheet and in the description.
The Driver's Perspective damn thats rough. Boost is the ONLY way to make power with these
@@aaronp9835 also costs twice as much, decreases reliability, fucks your classing for autocross and totally runes the driving characteristics of the car.
I installed JDL UEL (unequal length headers) on my 86 without taking off the heat sheld
Does the JDL header include an overpipe?
no it didnt. thats likely why.
Omg that first start! I’m so excited for headers and a tune....so excited. Thanks for the video!
Many months later it still hasn't gotten old.
Nicely done.
Thanks!
I'm new to the upgrade world, but am planning to do some things with a similar mentality as your build. On the header you just ran...is that legal in CA and/or do you have any concerns about that? I'm also really interested in what tires you choose...I have the TRD wheels as well.
Tires depend on intended use, I actually think the factory Michelin tires are a blast. When those wear out on my TRD wheels I'll probably replace them with the Continental Extreme Contract Sport tire in the same. My track wheels use 245/40/17 Bridgestone RE-71r tires, they are horrible on the road - lots of noise. As far as the header, it'll need to get removed at a certain time of year but I keep the exhaust quiet and retain the factory front pipe. :-)
The Driver's Perspective Nice...I'll be watching!
You still have the car?
They changed the gear ratios for the 2017 toyota 86 models... they also added 5hp and 5tq... Im not sure if this would even make any difference in gains here but Im wondering if adding a cold air intake would improve these numbers at all
The factory intake is the best, I've tested a Perrin intake and removed it because it caused nothing but problems and did not help power at all.
NMC Tacticz The i take and heads flow faster than the exhaust side. This is why the easiest NA gains are headers, hands down. Co(e85)ugh is right there as well. Me personally, I wouldn’t touch the intake unless you’re going FI
Classified Project They had a five horse power and 5 pounds of torque peak horse power but the mid range is much higher
Nah bro Subarus claimed 200hp is from the crank not the wheels ! So if that’s 206hp is to the wheels that’s amazing !
Saw him mention he runs E85. the FA20 loves E85, not surprised of the numbers.
It might have been a poor choice of header to remove the 'dip'. Aren't equal length headers better for that objective? Did the car get a 'tune' before the dyno? I'm looking for the best header under a grand, strictly to remove that dip, possibly without adding a new exhaust, still an option or will it be pointless without the cat-back? With the weather warmer and more humid, what are the likely adjustments in output?
EL usually give better hp at top end
Do they not sell the Openflash Header anymore? I can't find it anywhere but see posts about it all over the place.
That is my understanding as well.
No pic of the integrated over pipe?
206 to wheels what I made 188 consistent with e85 front pipe headers and what not
Every dyno is a little different, those are still great numbers.
wait.... why in the world would you dyno the car with both the stock header and aftermarket catless header on the same tune? The tunes for stock and catless headers are totally different.
OFT comes with a few tunes, but only 1 is E85 (the one he used). So stock header, running E85 with OFT, you use Stage 2+. Then this vid is on the header, not the tune. By changing header and tune, we wouldn't know what just the header is worth. Keeping tune the same both times shows us what one change is worth.
Hey awesome review. By chance were you selling your TRD exhuast, if so ill be interested.
Shoot me a message, it is for sale and I need to clean up some space in my garage.
nice video! one quick question, if my car is only 2 months old, do i still need to get new gaskets for the headers?
If you do decide to use the old gaskets I’d check for leaks and if there are leaks just get new ones and if not we’ll then you’re good
@@bigtatas0299 thanks for the advice! Have a nice one
Did the stage 2 tune get rid of the cat deficiency CEL?
Edit: I've read a lot of complaints from people saying the CEL still persisted or came back after a few miles.
Zero CEL with the Stage 2+ tune.
The Driver's Perspective ok thanks. I just ordered some uels and the oft v2. Hopefully no cel.
You will be just fine, enjoy!
So you were running E85 in STX? Uh, that’s illegal, and not exactly a small change. That gives you a good bit more power vs everyone else.
I always switched back to pump for SCCA events.
@@TheDriversPerspective Cool, gotcha!
My question is what fuel mileage difference did u notice if any after header installed
Zero difference in fuel economy by swapping the headers.
very very interesting that you had near zero gains. MCM had huge gains from header as an example
how much BHP would that be at the crank and how fast is the car roughly now 0-60 and 0-100?
Assuming the car has roughly a 15% loss from drivetrain, the car makes 205BHP stock and puts down ~175WHP, this is now ~240BHP.
@@TheDriversPerspective damn thats some good results! Didnt know it was possible to get those numbers from an 86 without extensive modifying.
@@yaz258 yup, and it is the perfect amount of power. If the car came like this from the factory I think people would have been more happy.
@@yaz258 He is running on E85 though. Not sure you realise as it's not mentioned at all in the video which is pretty sneaky I feel.
@@glenmiester Sir, are you blind? prntscr.com/mwn8h4 He literally has it listed in the dyno results
did it increase the fuel mileage?
Couldn't tell you, I've never measured it with this car. It is all about how many smiles per gallon I can get.
So with the oft e85 tune you can just swap to e85 without other modifications?
Number1 8sixfan Im pretty sure you need a flexfuel kit on the car to run e85
Is that an extensive fuel system overhaul?
Its around 150whp stock and you have 206 whp thats 56whp over stock
You'd never get those numbers on 91/93 octane though with just bolt ons /:
Totally agree, I bet this is around 190-195 on the same dyno with 91 pump gas. I'll be going back to test this at some point.
R u running on oem exhaust and name of header?
I am running a Thermal R&D 2.5" exhaust with a huge helmholtz chamber and the header is an OpenFlash tuning header.
What is the stock whp
170whp.
Should've did dyno run before header install for true comparison.
I did...data for that is later in the video and I also have a pre-header install dyno video on my channel.
Anybody know where i can order the OFH OFT combo?
The OFT header is no longer available, pick up the Tomei, JDL or Borla.
@@TheDriversPerspective it's available but you have to inquire to them directly and it depends on where you live whether or not they can sell you one. I live in Japan and they were willing to sell to me.
@@I-didnt-ask-you Good to know, it's a great header, I love mine.
Burako Shimazaki how do i contact them? It seems like its a good deal and from videos i really like the sound and the aim of their engineering. I seen it on this site but idk if it’s still active/legitimate? clubstore.brzworld.ca/product/openflash-tablet-openflash-header-combo
When a preformance shop does a stage 1 tune on the car what is a reasonable price for the tune?
Stage tunes are just a naming scheme aftermarket companies came up with. For a BRZ or 86 a Stage 1 from OpenFlash is just a slight retune on the stock map with a factory header. If you are in the market for that, spend $499 on an OpenFlash tablet and you can install that map in about 5 minutes yourself in your driveway.
The Driver's Perspective so most people just purchase the tablet and do it on their own? I'm looking at 725 for a stage 1 tune and a cold air intake installed. I'm assuming if a shop does the tune, that will not include the open flash tablet? What if I wanted it back to stock? Thanks for the info👍
Skip the cold air intake, it is worthless on this car. Factory air box design is so complicated that the aftermarket is really going to struggle to make it better. I went back to a stock air box after having issues with Perrin intake. Just buy an OpenFlash tablet and do it yourself, you can reflash to stock at any time with the tablet as it holds your stock tuning file.
I have a few videos on how to flash the car, it is super easy to do!
The Driver's Perspective already bought the intake so I guess it's going on. What kinds of problems did you have with yours and is it wise to buy a used tablet, unmarried v1? It is through PayPal? Just paranoid about doing things on my own. Don't want to screw it up.
Kris McKinney sell the intake or return it. The fuel trims will be out of spec with off the shelf tunes, may cause knock and poor throttle response. Used tablet is a good value if you know it’s legit.
My car knocked and had funky fuel trims. Not worth it.
What gear were these dyno runs done in?
All fourth gear.
did you tune for OPH？
Yes, I used an OpenFlash Tablet with an off the shelf v4.0 Stage 2+ E85 tune.
Did you do a 93 octane dyno run? I notice you are running e85 from the dyno sheet
No 93 octane in San Diego, but I am going back for 91 octane runs in a month or so.
@@TheDriversPerspective late to the party..but, did you ever do the dyno on 91oct?
There’s no way you make 206 whp on 93, I have a Frs on e85 and only made about 195ish, dynojet n everything
This was all done on E85.

Whatchumean only 1 hp lol . That’s good compared to engine hp and wheel hp . Engine hp is 205 , to the wheels is 170 ....
The end results are amazing compared to stock! I think it is interesting how close the curve with the 2017+ engine running just an E85 tune is.
Use ECUTEK
ECUtek has its place but if you are not going with a boosted set up the OpenFlash tablet is a fine choice. I've used both extensively but ECUtek is my least favorite from an enduser perspective.
The Driver's Perspective with Ecutek and 93 oct gas I get 206 with deop in KN, front pipe no cat and no resonator no Muffler !! Then with Fiebruz IMRE and e85 those numbers climbed and 3” perrin CAI 234hp
This things needs 225hp stock
I do agree the added power of a header and E85 would have made this car far better received by the public.
Such an expensive car and my wifes 2014 Malibu ltz turbo smokes them and my RSX when it was stock walked them hard. Don’t get me wrong they’re great cars and I would love to own one but they’re so under powered that makes me cringe. My next car will be an ecoboost mustang 6speed with performance pack. Just intake,DP, tune and they make BIG power
Drive one on a twisty road and I think you'll feel different. This car isn't about power, but with about 200 at the wheels it's the same power to weight as an S2000. Plenty for fun.
That's what I was thinking - you've effectively made it S2000 level power, a great place to be.
lol you had someone do the most basic beginner install for you
