Looking for some advice on my setup

[BLTM]

Whats up guys, I know there are many thready out there which state the best few bolt ons for quick power adders and I already have a couple of those, along with quite a few other bolt ons. I have the sct tuner, and whatnot and I have a pocket full of cash that needs to be spent on some go fast goodies.

I am running:
K&N CAI
SLP Catback
Along with a list of other mods that don't add HP.

I want to do a 2.76 pulley setup, AND the supporting idler pulley i believe.
I need to also pick up a mid pipe (catless).
Everywhere i look people say headers are not worth the money, is this true?

I want to be pushing 450 + hp to the wheels.

Is there any other things I should be considering, posi ported eaton and TB?

I'm a noob with mustangs as I just picked up my cobra 3 weeks ago, if this were an F body, i'd be answering these questions for someone else haha.

Thanks for looking guys.

If you have any of these parts I listed, ill buy them from you.... Ported TB, Pulley setup, mid pipe etc. lemme know!

What mods do you have that don't add power?
A Billetflow differential brace and subframe connectors are nice addition. The brace is almost a must.

I would go with a full 4 piece idler setup. The stock stamped steel idlers are prone to exploding, damaging belts and radiators.

Catless midpipe + SLP (loudmouth one) is super loud....imo. I agree with Emwun, subframe connectors and a diff brace are worthwhile and at 450hp, longtubes are not needed. Depending on how much $$ you are looking to spend, a 2.76" pulley, 60lb injectors, BA 2400 MAF, BAP and 4 piece idler set would make you VERY happy.

I have:
IRS low-profile blots
Maximum Motorsports Full Length – Sub Frame Connectors
Liberty 26 Spline Input Shaft
Centerforce DFX Clutch & Pressure Plate
Ford Racing Throw Out Bearing
Flipk Intake II
Fidanza Aluminum Flywheel w/ replaceable contact section
Maximum Motorsports Clutch Pedal Height Adjuster
Fiore Micro Click – Clutch cable Adjuster
SLP – Line Lock
Ford Racing - Drive Shaft Loop
H&R Race – Lowering Springs

If I'am pushing 450+ HP, I would be very happy. It seems like headers are not a necessity to achieve this?

Why 60lb injectors? Thats NOT needed for hp in the 450 range. A different maf sensor maybe.

 

[Emwun Garand]

Billetflow IRS brace, most def.
4 piece idlers.

 

[Darko]

Billetflow 4 piece idler kit, 2.76" SC pulley, tune, exhaust & intake and 450whp is no problem. Like others said IRS brace, sub frame connectors. Id also do some cooling mods as well. Look into the Fluidyne Heat exchanger.

Yes yes ... Bassani Catted X (comes with the straight pipes also)!! :beer:

2.76" pulley should get you in the 450 rwhp range...

 

[SVT_Troy]

skip the headers for now and just do a pulley swap with some dyno tunning. Other are saying to get the brace before you destroy your rear end which can happen on stock power levels with some wheel hop. It sucks having power and not being able to use it....Ask me how I know :mj:

My bassani catted x did NOT come with any straight pipe to eliminate the cats. Mine are welded on.

 

[Emwun Garand]

Weird. I had a Bassani catted X on mine when I bought it and the cats did NOT look like that.

The injectors may not be needed now but I doubt his mods will be done after he reaches 450 hp.
When I had my procharged 99 Cobra I said if I bought an 03 Cobra I would never have to do anything to it. I would be happy with the stock power. Fast forward 2 years and I have went through a ported blower and now have a twin screw. Do the mods ever end?

You will have absolutely no problem reaching well over 450 rwhp on stock exhaust manifolds. I would save that for much later.

The modding never ends! I know everyone was saying headers are not important at this time, but i want to save my self from having to do them in the future.

Can someone post a link of a 2.7 pulley setup (4 pc) right? I want to buy asap. Whats good?

 

[Emwun Garand]

Here's what I run.

Reichard Racing 2.75" upper pulley

Division X 4 piece Dual Ball Bearing idler kit with bracket and hardware

Call Lethal and they will get you set up with the correct belt size too.

 

[CobraBob]

I know you want a 2.76 upper, but you can go with a 2.90 Reichard Racing upper and make 450rwhp+ with a good tune. Less chance for belt slip and less generated heat. Here was my combo that got me 457rwhp and 480rwtq.
2.90 Reichard Racing upper pulley
4-piece Billetflow idler set (but I recommend Metco)
Accufab throttle body/plenum
Magnaflow catted X-pipe
Steeda catback
Amazon Tuning Solutions tune (93 octane fuel)

Ya I got the 2.81 and I'm up in the 480s! Oh and just installed my gasket! thanks

That might be true, I've also heard that changing out injectors with the blower still on can be a pita. I've never done it, so I'm not sure if it is. But later if going to a ported blower or twinscrew would be the easy time to swap injectors imo.

 

[HURTNEM]

You can get a 2.90 upper pulley and you won't need to buy a 4 piece idler set. You won't need 60lb injectors or MAF either. I ran stock MAF and Mafia with a ported eaton, so with the stock blower you'll be fine. The 2.90 upper only is the cheapest way to your 450RWHP goal since no extra idlers are required.

Get an IRS Brace and some sticky tires to go with the 2.90 upper and you'll have a new car on your hands! I'm from the South Side of the CHI. Congrats on your Cobra.
