Crick water with craw dads and poly wogs in there to. Might use some of those HP red plug wires but I heared the might mess up the test. A lot of belly ackn then.

I'd use spring water since it won't freeze, lol!

What real world engine would show zero difference between HP manifolds and headers?


Excellent question even if it is rhetorical.

Rhetorical answer time, a non-running engine or one running so poorly as to be non-functional.

For those wearing blinders the point of discussion is that without knowing what cam and without tuning for the application this dyno is about as useful as a square of used TP. Do headers help? Most of the time but they have their issues as well. They are noisier, they put more heat into the engine compartment when running, they can have fitment issues, they are more prone to leaking, many hang real low and get damaged, finally they can make other maintenance chores more difficult. Cost is also a factor as the ones that have less of the issues mentioned are likely to be the more expensive ones as well, Quality costs.

If your only concern is HP then headers are part of the plan. If the issues I mentioned concern you then headers may not be part of the plan. Also, the more mild the combo the less help headers are and the more likely the issues headers have are important.

Jeez......this thread is amazing. The guy makes a YouTube video showing us the results from a simple parts swap while the engine is conveniently on a Dyno and people here go into full mangina mode,

God damn.

There was a late 80’s vintage BBC LS6 crate engine on the dyno here the other day.
It was a pretty low use piece that had just been freshened. Cylinders honed, rings & bearings, valve job, new springs, and a comp 282S magnum sft cam.
10.2cr, pump gas, Holley 650DP carb.
Runs manifolds in the car.
Motor was tested with the manifolds and some 1-3/4x3 headers.

Manifolds - 471tq@3600/438hp@5500
Headers - 523tq@3700/463@5600......... better by 52tq/25hp(peak vs peak).

The pulls were started at 3000, where the tq numbers were 448 for the manifolds and 504 for the headers.

Nick actually prefers manifolds over headers. He is definitely a stock component type of guy. If his video was titled "Headers make 44 more HP than manifolds" it would be fair to criticize him. He did not state headers are better than manifolds. He noted thru his testing of the ENGINE ON HIS DYNO- which he did not build and he knows NOTHING ABOUT ITS INTERNAL- made more power with headers. He didn't say yours or my engine would make more power with headers. Alot of fight wasted on Nicks garage. Save the fight for Powernation calling an 8 3/4" rear an 8 1/4". Or the guy heating 440 conn rod small ends cherry red with acetylene to fit the wrist pins. Nicks on our side and he is not deceptive.


Keep old mopars alive.

Optimus Prime and the Decepticons....

Its Nick's new PooTube channel.

Take whatever I 'say and do' and rip it to pieces with fake-news and drivel...
Sure to be a BIG hit with all the NAY SAYERS around the World.

Meanwhile 'BACK IN THE REAL WORLD',,,,YES, its needs to BEE a slightly better vid by Optimus, so we know the variables.
He loves saying ''I DIDN'T BUILD THID ENGINE, I DON'T KNOW WHO DID, BUT'' I'm gonna use it for a dyno header test... whistling

Come on NICK, please stop playing the 'innocent onlooker' and GIVE US THE FACTS!
We can see that ain't no 440 ROADRUNNER engine from an A12 car, they only made 1400.


Its got pre 68 heads on there and low comp pistons...

Why 'o' why would you put a SIXPACK ON IT??? spank

I'm gonna put my spare 1050 dominator on my 318 POLY D200, just to see what happens... fan panic
It has got 'restrictor rings' so it should be fine, 950cfmish... help

Always liked Nick and his HEMI vids.

But when he started doing CRAP engines that can't get 'out of their own way' I became suspicious...

The 426 wedge, got us ALL HYPED UP to the MAX and its an INDUSTRIAL 'LONG CRANK' POO MOTOR!!!

WOW NICK, you certainly 'shot yourself in the foot' with that pile of nastiness... fan
Followed by the lopo '50's HEMI' of 'SUPER LOW POWER' and hardly worth the time to set it up... ozbbq

Hopefully we can all move on from the MADNESS of 2020 (early-21) and do some REAL ENGINES worthy of a POOtube vid.

We want 2000hp 'DYNO breakers' like my good friend Tom Nelson does... panic

It takes ''A 'LIFETIME' TO GET A GOOD REPUTATION, AND A 'MINUTE' TO DESTROY IT'' argue

I come here to bury NICK, not to praise him, the 'bad vid's that men do, lives after them and the 'good vids' are interred with their bones.

Long live NICK! pity

Some guys on this board have Trump living large in their head. You have Nick living in yours.

Have you tried Engine Masters? They detail pretty much everything inside their test mules. Because details do matter. Plus, you can have three guys living in your head with that show.

I didn’t realize Nicks videos were supposed to be technical video seminars.

I thought they were just supposed to be entertainment.

If that is true, then maybe Nick should be a little clearer that he is 'for entertainment purposes only'? It seems that there may be a bit of confusion on his purpose.

Personally, I learn something from most video posts of dyno sessions. Even ones that are fairly tongue-in-cheek like the Engine Masters beating the heck out of the header tubes. The important thing to keep in mind is that each test is on one particular combination. And may or may not have any application on any other combination.
