Header comparison. NO E85
 

RevWorks header + full nameless exhaust + drop in perrin filter.

E85 only. Waiting for a pump gas dyno

P&L Header Green line is pump gas I guess.

JDL header Only has been tuned on e85... doesn't really count...

Now everyone do me a favor and look at the torque curves.... Look back at the revworks.... Yupp.... thats some awesome. I'll get some better dyno's of the RevWorks header soon. And some comparisons. Everyones thoughts?

My thoughts are the only dyno graph that looks remotely realistic is the P&L one. Since when did changing an exhaust component give you a proportionate increase in torque across the range? (ignoring the remap tweaking in the torque dip).

I thought the P&L green line was pump gas too. Only difference was the red line was no tune and green line was Visconte pump base tune.

If you guys want to Paypal me some money for the dyno, I will go back and dyno my JDL UEL Header on pump gas.

I think it will look very similar, just a little less peak power compared to e85.

id love to see the results of the SARD headers... anyone thinking of buying them??

I'd chip in $5 towards that. I'd want to see all the data that goes with it though, including atmospherics, dyno settings etc.

No comparison really until you get them all on the same dyno, otherwise the variance in dyno readings could just as easily impact the results as the actual performance of the header.

Look at the scaling on the revworks dyno graph, for instance. The scale covers from 50-450 ft/lbs, of course a torque curve on that graph is going to look flatter than one on a graph scaled to cover 75-200 ft/lbs.

You got this one wrong. THe light colored lines are pump gas but they DO NOT include the header.

Also, the P&L Green line IS pump gas with visconti map.

So, my thought is...
"You bought the wrong one silly" :bonk:

LOL, just messing with you....

Most of the headers do allow for dip removal with tuning. stock cam timing around the dip is not optimal with a header since it is setup to try and get around the limitation of the stock header.

Your plot look great btw :thumbsup: where did they put the temp probe and what correction factory do they use?

And data logs from the car with a proper tuning tool like ecutek or brzedit, sample rate for the torque app is terrible.

What he said.

I do like the attempt to compare without E85 though since a lot of the dynos we are seeing are skewed by using E85, but most of us can't or won't use E85 for our cars.

Wait a few more months when there are more headers in the wild and pay attention to meets with dyno days. Those will best illustrate the comparisons. Nice power with the revworks though, pity you didn't get a baseline.

That nameless dyno shouldn't be there at all. It's not a product we can buy...let alone independently test at this time.

Once i get my jdl uel ill get my car on the dyno as a 3rd party with 93

Good start for a header comparison. A few things to consider.
Each car is different, each dyno is different, conditions (temp, humidity, etc.) so all data must be normalized. A baseline run needs to be done which I don't see on the Revworks dyno, so the delta (in percent) cannot be calculated nor compared to the others. Consider adding notes such as UEL (typically uncatted) and EL (catted I'm assuming), which tunes they were running, and all known mods.
@Simmons I plan on getting a tune sometime, but with news of the furlough I'm not sure when that will happen now. Whenever it does happen thou, I'd be glad to share the graphs.

edit

I like the P&L and JDL header

John when i get my jdl uel come play on the dyno with me? @Visconti

Yup

Would love the OP to out a pic of the header next to the dynosheet

Ill call you when it comes in.

Yes, that dyno is Exhaust only, no header, then header, then map switch to Visconti tune. There was no fine tuning done to get additional power out of the Visconti tune with the header, so most likely there will be more power to be had.

I proposed a contest to Paul @ P&L and he liked the idea, so once this group buy gets shipped out get your headers on, and your dyno's and cameras ready! More to come the closer we get to shipping date.

Edit: I also only have the stock airbox/panel filter.

Subscribed. Even though I have already ordered my header (RevWorks), I will still follow this thread. It'll be interesting to see the numbers and comparisons. Thanks for compiling this. Might be nice to make this a sticky.

I agree with this as well. It would be nice if we could figure out a baseline for the dynos on the thread so that things are more even. Sorry to hear about the furlough. Hope it all works out for you. This car tuned is awesome.

^^
Yea, blue line is without the header, on 93 octane.

Black line is E85 with 4-1 EL Header (catted), CAI, overpipe, resonated front pipe, and a STOCK cat-back.

EDIT: Black line is E76 (flex fuel sensor reading at the time of dyno).. with a better flowing cat-back, catless Header, and purer E85, who knows... ~210 whp could be possible. ;)

Thank god for Arizona, e85 pumps all over the place throughout the state. 2 in my own town less than 10 minutes from my house.

Isn't there already a header comparison thread with pictures and everything? Just get them to edit it to differentiate between E85 and pump gas.

The original post has tons of misinformation, I would just let this thread die.

Saying "E85 doesn't count" is like saying "Cars with LIGHT racing wheels don't count", IMO... if you got access to it and can fork up the money for it, it's ALL good. :thumbsup:

20-lb stock wheels VS. 14-lb racing wheels = 93 octane VS. E85 fuel

I'd like a live feed video. So that you don't use an old dyno or something, pocket the $, and buy yourself another mod :D

Jk!

LOL, that could be arranged. :happy0180:

The main reason I Only dyno'd on e85 is because that is what I plan on running this year. I did drive the car with the header and same mods on pump gas for a couple days, I didn't feel any tq dip on pump gas either.

Go dig through the 100+ threads and 100+ posts and get back to me. Sometimes it's best to start fresh with current results.

Updated main page. If anyone can find more dyno's that would be awesome. Also I under stand these are on different dynos yada yada yada. It's just something to look at. I'll get more dyno's from every header and update the main post later.

Here's a pumpgas FA20club

Here is mine w/ AEM intake and Unichip running the FA20Club header (catted). I am going to another dyno on Saturday to validate:

This thread already has all of the information you are compiling plus more including pictures, videos, etc. I thought it was a sticky in here but I guess not, it should be.

interesting... don't know how I missed that.
