Hey guys like the title said , I was lucky enough to pick these up from infinity on MBWorld for 350$ and what a great investment! This is the link:

Shardul was helpful answering questions as well even though the sale was already done through infinity ...

I have 180 pulley, PLM HE, upgraded Bosch pump, PTE thermostat, Jeremy OE Tune

Well here are the results..all on the same dyno and same conditions except humidity was higher on post install, no retune just these babies added.


Pre shardul headers : 445hp/552tq. 85.29f, 29.92 in-Hg, humidity: 38%, SAE: 1.00

Post shardul headers: 464.2hp/574.03. 84.07f, 29.75 in-Hg, humidity : 56%, SAE: 1.01

Now the dyno operator said that on the chart I had 30hp/30tq gains over the entire power band until redline...

Now guys I am having the fuel system with looped fuel rail and 550 injectors go in hopefully this week and get a retune from Jeremy, I'm sure it will go even higher!

Thanks shardul!

Be careful here, you gave credit to the S man

Ban hammer in 5, 4, 3, 2,

Great to hear about the reults my friend

AKnight55

Re tune and im sure you will gain even more power

Hulk

Yup that's what the dyno operator said..its in the works

Need to get my ported tb and fuel system in and retune

Infiniti

awesome man. hulk is a good guy and as we all know Shardul is the truth.

MRAMG1

+1

Hulk

Thanks for the great price bro

DVC

Congrats Hulk!

Can you please post the before and after AFR?

Hulk

Damn...I don't have it but it did go lean at one point and then dumped a lot of fuel at the end so fuel system is coming just in time

MRAMG1

Ah Hulk, if it dumped fuel at the end aka high rpm, it still had plenty of capacity. Just a thought.

PS: I DO subsribe to the larger fuel injector and rail mod crowd

Hulk

Yup it went down close to 9 or 10... So a tune is in order with the new fuel rail and injectors

kustom2k1

Great numbers, where did get the dyno runs done?

Hulk

Rage-tek, good guys there, but their dyno gives lower numbers than the mustang lol..be forewarned, theirs is the real heartbreaker lol

RedBullJnky

Funny, that's what Nemo and Allen say.

Hulk

Lol...Al said that when he was tieing her down the first time, and I didn't believe him til he ran it

RedBullJnky

I still don't believe him.LOOL

Hulk

Lol!
I think he has a diff version of a dynojet that he uses to destroy people's egos,lol

Instead of starting a new thread I'll ask my question here.

In order for long tube headers to be useful do you need to change or delete anything along the exhaust like cat delete or race cat or resonator delete etc. Are those mods for sound and if you install long tubes (and tune for them) but NOT delete anything or change mufflers, will you still get gains?

Hulk

Yes u still gain without deleting because you are getting rid of the restrictive manifold, but long tubes will gain the most and usually cats are all gone unless it's custom and get high flow cats
