Drift-Office : Borla UEL Header... TUNED.
 

Hey all, thought I'd share our findings with our recent calibration of a customer's setup with a production Borla UEL header on his FRS.

First, a quick re-hash : typical 6MT baseline @ 165-ish, stock wheels, stock intake, ARK Exhaust running 92 Octane. I won't bore you with videos on this one since there's plenty of BRZ / FRS Borla UEL videos on YouTube, so here's the nitty-gritty...

Coming in from having just installed the header with a 100% STOCK ECU setup, here's the baseline in 3rd and 4th :

Neato ~ it's pretty apparent that some of that dip has gone away, though it's still there... There's an increase of about 10WHP in PEAK numbers in 4th gear, not as much in 3rd... and cutting to the chase, when we were done with our calibration, these were the final results :

I was hoping to cross the 180WHP mark as with most of our Stage 1 NA tunes, but in this case, the engine just didn't respond to any adjustments beyond that point. Granted that all this doesn't seem like much but it isn't until you overlay a typical baseline from another 6MT is when you see what this header does and where it really shines. :)

So based off that last chart, I think all of you who's keen in getting rid of that torque dip, your prayers are finally answered. :) At the lowest point of the dip, you're looking at an additional 15#s of torque in that void, filling it up very nicely. In this case, you can expect an increase of 10 - 15 in terms of both power and torque thru the entire range.

So the bottom line in a nutshell : All UEL headers are not created equal (Get it?!) and requires tuning to optimize and realize their gains! With limitations in octane based on locality, you might not get the phenomenal results you otherwise would with E85 and such but you can expect to "feel" a much more of a planted sensation and linear performance with a proven setup like Borla's offering.

I've got a Rev Works UEL header to tune in the upcoming weeks, so stay tuned for more when it develops! :)

Regards!

Getting rid of that torque dip is amazing

In for this...

Nice work!

Holy Grail!

I assume the car is now octane limited. If we can get 93 octane, non ethanol, non oxygenated, non swill fuel, we may see a flat torque curve, right? ;)

Bob, do you think there is any chance 140lb-ft can be extended to 7400rpm? What do you think the bottleneck is beyond 6500rpm?

And also, how loud is this combination?

The revworks should make well into 180s cuz the borla is poor quality with a retarded collector lol great tuning tho

So it looks like headers have answered our torque dip prayers. Nice! Can't wait to see more tunes of the RevWorks, JDL UEL, and side by side with the EL's (FA20club, P&L, Nameless when released) Thanks for sharing.

Ditto:thumbup:

My Revworks needs you!!! Here is my E85 tune after slapping the RevWorks UEL header on. Dip is still slightly there, but I hope this can be flattened with some work :)

Here it is over my baseline:

Finally! Someone got it! :)


Cheers!

Bah. Word puns are not punny.

What HE said about what THEY said....

We got it. We just ignored it.
You won't be tuning many cars in the punitentiary.
Ah well, you can tune a Toyota, but you still can't tuna fish.

what numbers are you making with the rev works on pump gas

Sorry guys, I don't have the info yet. I was already on E85 when I installed it. I will need to do that since I will need a revised pumpgas tune for the header as well.

Nice stuff man!! The Borla UEL headers have big a big hit with us!

We've sold so many of them in our ongoing Group Buy and have heard nothing but awesome reviews from our customers. Even sent some to Australia and South Africa and they absolutely love it!! Amazing sound and performance on the 86's

Hope to have that here soon! :)

Any chance they'll start using GTAW ('TIG') to weld those headers in the future? I've been put off by the appearance of the welds and numerous quality control returns buyers have been reporting from various shops. I love the sound of Borla and would consider a UEL header considering the gains people have been pulling off (dips in those graphs are basically gone after tuning!?), but I'm picky about weld quality (QC-7 GMAW/GTAW/SMAW certs from Hobart).

Lies, every time I've heard about borlas it's about the complete piece of quality shit they are... And I own one... Collector is garbage and its devolving surface rust after 2k and rust on the welds. BORLA UELS are complete crap.


And yes I do plan on buying a replacement JDL or revworks UEL, and yes the borla is that bad.

Mind u it's not that I'm saying you sell bad products or anything like that, but borlas sell because their cheap. And I feel as though this time borla F'd the donkey on QC. It's not the suppliers/venders I'm angry with its BORLAs problem.

Umm i have borla uels and am very happy no leaks , no rust and my welds came out good , yes there was a bad batch at first , but they corrected the issue, shit happens and they stood by their product 100%

I had no leaks from the get go, but it's still rusting, and the collector is 4 tubes straight welded together, no semblance of a merge at all... AKA a bag of ass. As for the rust, I'd keep checking, I'm just gonna end up buying a JDL UEL, because revworks didn't put an expansion joint on theirs for FI.

Excited for this part. :)

-Matt

Ditto.

Hoping mine might be available to install next week Matt...hint..hint.

Hahah I'll try and see what we can do. ;)

@Adeets we seriously get the point that you hate borla :) (not saying I'm a fan boy)

Any word on tuning for a JDL UEL unit? Wheres the love for the phoenix local boys <3

Bet you still have it installed on your car ;)

Indeed, JDL has got a header coming my way (after they take care of their backorder!) for testing and evaluation. Meanwhile, next up Rev Works! :)

Cheers!

Yeah, JDL has a back log ATM, if I get my linear HP delivery I'll prolly keep it on there till I go e85, I need the nameless down/up/thru/high flow cat pipe before replacing it... Well that and replacing the perrin catback, beautiful note but to heavy for my tastes.

What do you have on there now?

Perrin lw crank pully > PST CF driveshaft > vortech supercharger > borla UEL > stock whatever pipe > perrin resonated cat-back. Moto-east tuned. Dyno is in the forced induction threads.

Btw the borla UEL loses its rumble once you go FI, I think it's related to the collector design, the JDL seems to keep it with FI.

F1Point4 has the vortech system + Borla and he still has the rumble.

Yeah but I think we're tuned in a very different manner, you can see it in the dyno's shape.

is this with the stock overpipe and front pipe

For the Borla tune? Yes.

MOAR! Borla Calibration Update ~ 10.25.13
 

So I finally get the time to update a bit more of what we've done in the last couple of months...

So we had a sub 600 mile FRS come in to get tuned, and wanted it to rev out to 8000RPM. Car was stock sans the BORLA UE, an AVO panel filter, AVO intake and Perrin 2.5 inch exhaust. Here's the pretune and tuned runs.

Results :

Attachment 55230

So now when we now compare this recent calibration and the original BORLA tuned in this thread (now @ STD Correction Factor) and the difference being only the OP and FP, this is what we have :

Attachment 55231

As you can see, everything is in line with what we've come to expect : rumbly sound, maxes out @ about 180WHP.

Attachment 55232

Now this next one will be a bit of surprise... here's the 2nd Phantom Full-Throttle ESC fitted with a BORLA UEL against the previous 2 runs. Not really an apples to apples comparison but a fun one none the less!

FYI, I should note that the 4 Borla's I've now seen (I have a 6AT setup that I tuned but I don't remember where the dyno chart is. :confused0068: ) haven't had any issues of fitment or QC failures despite what's been discussed on this forum... I'll update this space as I get more that come my way!

Cheers!

^^ damn, made almost 1 HP + than mine.
