*Note : Rev Works dyno tune updated, results herein.

Ello :

It's been awhile and someone reminded me via PM that I had yet to post the results of the UEL shootout from last year (yes, we've been busy!) so without further ado, here are the results...

Readers' Digest Version ~

All cars were 6MT, 92 Octane and most had exhaust systems, sans the vehicle with the JDL UEL which only had a stock exhaust system and an AVO Panel Filter (Dry)...

As you can see, the results are all fairly similar given the variables;

Similar Octane
Similar Tuning Philosophy
Similar Exhaust Components

That being the case, the two two performers will then be JDL and Borla in this case :

So the question now you have to ask yourself is what would be more important to you - the slightly better bottom end torque or the better top end performance with matching torque? Feel free to form your own assessments!

awesome, thanks for the comparo Bob :)

Very interesting!!

But what we really want to know is, are the header flanges flush, and If not did you grind them down?! ;-)

But seriously, awesome work Bob and Bill, great gains for those SC or not wanting FI.

How about e85?! :-P

The results do not take into account the following :

1) Price
2) Price to Performance Ratio
3) Quality
4) Fitment

It only takes into account the yields that we have attained thru the same dyno with the same tuning process with the same fuel... :)

Regards!

Are they skat?

Nice job. Love my borla. It's my favorite mod. My car is tuned to perfection and it sounds better than anything

UEL shootout needs the OFH! Good work, though! Thanks for the info!

i cant belive the borla made more tq in this test. Its the worst finished header ive seen in a while

Borla appears to be the better option if I'm looking at overall torque.

I'm not surprised by the results :)

Good work Bob!

Wow, impressive.

Huh, Borla. Too bad no OFH in the mix.

This.

While true I dont look at my borla uel so I could care less. As long as it performs well and sounds good, its all that matters.

The only Borla that i have ever seen in person (it was awhile back when they just were released.) used a smaller diameter runner size than our header and what a lot of the other popular ones use. Not sure if that has changed, etc but that would explain the tq down low. Short of FI...NA parts like headers, cams, intake manifolds, etc are for the most "give and take"...

And speaking of that, I'll have the results of the EL headers up here soon, including the JDL v3 ones pretty soon! :)


Cheers!

:thumbup:

Will that include newly released Nameless EL header as well?

As soon as I get mine installed, I'll contact you guys for live-tune.

ya it would but ive seeen the inside of that collector, it looks like smores of weld, pipes and a visit from a hammer lol when they came out their dynos were always much lower then the higher end headers

JDL UEL for the MF win. Piece of art and performs. Would have been great to have the rest of the exhaust in there and the numbers would have bumped up a tad more.

I am curious to see how the JDL v3 EL performs versus Nameless. That's a battle I am sure most have been waiting to see.

Hmm is their a way to overlay the OFH dyno results on 92 octane listed early on in the openflash header thread or are the scale sizes too far off? That would be cool. Not sure about the tq dip area in comparison but the high end output of the ofh compares to the jdl header at about 190 i think. Thanks for this awesome comparison.. Bummer for revworks i think.

You could but the results for each of jdl and ofh would be from different dynos which would make drawing any meaningful conclusions difficult.

Bob, Thanks again for the great info. Do you plan to do an EL Shootout?
Cheers,

Thanks for the write up and information

I have the results of 3 ELs ready - the T1R from A&J Racing (Canada) , JDL ELs and HKS. I have seen the Nameless one but on a ESC project, not a NA one so that's not going to work. I'm sorta holding out for a few more days and if it doesn't come thru by then, I'll be posting the aforementioned 3 up first. :)

Cheers!


Bob @ Drift-Office, LLC

Come on folks! Someone get a nameless header in this man's hands!

Pretty easy to just remove the ESC.

I don't think that was the owners' intention. :)


Bob @ Drift-Office, LLC

Wow! Thank you for the dyno result

Surely he would like to know how much of an improvement the header is alone?

Get the OFH and FT86SF too.

Forgive me if I am reading the graph wrong. But what is going on at 4k RPMs on the JDL header? The power seems to drop quite a bit, then comes back up.

It's not dipping, just a sensory breakup on my end on the dyno with the tach pickup...


Bob @ Drift-Office, LLC

I have a JDL unequal and love it, sounds great and with my Drift-Office tune its really good down low and up top, big difference in the low end. I have a build thread with dyno graphs i will be updateing when Bob and I figure out what fuel my car likes because we know it doesnt like the pump gas from around my place. hoping to get 190 + when dialed in :) It is tuff doing it from a distance(e-tune) who knows maybe Bob would be coming up to the promise land (canada) ;) for a tuning session :P BTW Drift-Office is fast at shipping out it took literally hours to get out the door , cheers to productive workplaces !

The Borlas use small runners and have good torque at low RPM. From there though they are restricted by both the small runners and the poor quality of their collectors.

I should have bought the borla and saved myself some money. :(

That's not how all JDL collectors look. Mine looks like this:

And to be fair isn't that JDL holding the collector? Which pretty much guarantees that is the the best collector they've ever made vs. probably the worst borla collector ever from early production models?

That's only if you consider peak horsepower mostly above 6,000 rpm. If we're talking about which header delivers more power in normal daily driving mode i think the Borla makes a pretty compelling product especially considering the price point.

+1 for OFH (UEL) and Nameless (EL)!
