Isn't torque were the fun truly is at?
Isn't torque were the fun truly is at?
I don't feel like I'm missing any torque with my ported blower and longtubes.
I see ~14psi boost with the mods in my sig, and it murders the tires on the 1-2 shift now where it would just give a solid chirp before them.
2002 DSG HD #09617 NHTOC Truck of the month November 2012
Ported eaton/plenum/tb, 6lb lower, SCT BA-2600 MAF, OBX longtubes, JLP intake, FTVB, L-spec bilsteins, Hotchkis TVS, 22" replicas. Tuned by Ray McClelland of FTK
Typically a ported blower shows a 2# increase...ie MORE AIR FLOW As for Headers it depends..
Shorty Headers = waste of time...no gains.
Long tube Header people claim up to 18 RWHP BUT look how much it cost to gain that HP
you will also see a drop in boost...not always a bad thing. It also depends on How modded your truck...heavy mods show more HP...stock truck with headers not so much...It is really part of a puzzle...just one of the pieces in the middle of the puzzle and not a outside piece..IMO
HP is made by how fast you can take air in and how fast you get it out.
here is an example..maybe not the best....
Think of a garden hose and if you attached a pipe that is 3" in diameter you are not going to see a better flow. Now change that garden hose to a fire hose and you will see it flow way more...or having a fire hose and sticking a 1" pipe...too much back pressure and it flows less.

Firs I put the 6lb lower pulley and I was making 357hp to the wheels.I wanted to make it close to 400hp to the wheel. Know if you put all rest of the up grades that I have you will get the 400hp.

People also said with no cats that I would lose torque! I didn't, infact, I would be more comfortable if I lost a little bit.Originally Posted by Blind

You may need to re-phrase your first post as I'm having difficulty interpreting what you mean. Do you want the back end to be a different shape or do you just want to be able to spin out in it?
Discussions involving dyno tuning and performance add-ons is like the great debate. There are individual and tuner preferences regarding Mustang dyno vs. some dyno jets, best A/F ratios, timing settings and other tips and tricks depending whether it's being done for highest HP numbers, optimum track performance or a mix of performance and all around drivability for a DD type vehicle. Tuners can lean A/F and advance timing to maximize HP as well as tweet other parameters, if their main goal to give a customer hi HP numbers. A customer should have discussions with the tuner as to how his/her vehicle will be tuned based on their individual uses or goal. Getting references and then knowing that the tuner has a stellar reputation, then trusting that that individual will stick to that agreement and take exceptional care when tuning their vehicle, based their earlier discussions. If tuning on the edge will be done, then the customer should have been well informed and agreed to all the risks and possible consequences of doing so.
I have found some of the links below a bit helpful for me in getting a general understanding of dyno setups, tuning, A/F and such. There are far too many intricacies for me to ever be a subject matter expert. Also a link to my tuners philosophy,
