Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Development of New Products (Headers & IM)

Alright guys... I am posting this to achieve answers to some research questions I have.
If you are a NECO member, please respond to

I am talks with a company to make the following products:

Headers w/ or w/o y-pipe

Upper Intake Manifold

After Weapon-R dynoed the car this past saturday, they determined that the Intake Manifold and the Exhaust Manifolds are robbing us of power. Right now we have some options, but very limited. The options are at this time:

SVT upper intake manifold
MSDS Inc. Headers w/ y-pipe

I would like to know if anyone has actually dynoed the gains from these two products. If so please post numbers. Please keep the guesses down. I need real results if available, if not thats fine.

I know many people have had a lot of problems getting ahold of MSDS headers. This company would like to sell them for the same price if not cheaper than $600 and also would run an initial batch of 50 headers. Stock should not be an issue. It is projected that my car will be used for dyno plots. If not a dyno sheet will be done on a stock cougar to prove ACTUAL HP and TQ gains from the Headers.

As far as the intake maniofld... is has been proven by Many companies that Ford is very restrictive on the Upper Intake Manifolds, not only on our V6 motors but also the I4. (How you think they got more power in the SVT Focus? hehe). The company is willing to also take research time in making a new Upper Intake Manifold. This product would also be made in batches of 50 to keep stock and limit backorders.

This is not a wishing well... this is reality. The company wants to hear what you all have to say. Please post what would have to be done for you to buy these products. Also post anything the company should do (if possible) to make the installs a bit easier. (I am not up to date on the SVT Upper but I am aware of some pieces needed)

Thanks for your time,

I would be very interested in buying headers with a y-pipe if the price can be brought down under $600 and dyno plots look good.

Is Weapon-R the company that will develop these two products, or is that just the company that did the dynoing for you?

I can dyno before & after I put my headers on if you like...but I have mods. You interested?

I would like to see several things on the intake side of the engine. I would hope they could develop an entire intake system that could be purchased and installed in stages, but that was demonstrated (dynoed) to work synergistically. Also I an not opposed to them using currently available parts, such as the pro-flow MAF. I would be interested in the following.

Stage 1: Open air filter with heat shield and or new airbox. In other words a set up that had the advantages of the open air unit without the problems of heat soak.

Stage 2: Larger MAF and intake pipe (similar to BAT pipe). I think there needs to be an investigation into the need for the new pipe.

Stage 3: New intake manifold

I hope this helps and makes sense

Currently working on a Cold Air Box setup

Here is Chris Wang's dyno showing about 3 HP gain across the rev range going from a single Extrude Honed 1998 SVT upper to a dual Honed 00 SVT upper + 00 SVT 34mm lower.

So, a non SVT using the dual Honed SVT upper & lower would probably gain more. Maybe 5-6 HP? Probably more power available if the secondary butterflies were optimized or perhaps removed. Of note, I think your Leo Capaldi has gotten up to 320 + HP using a more extensively Extruded Honed intake. Mirko had 260 HP with the upper as well. So, maybe given enough Extrude Honing to match head port sizes its not that restrictive... Just my guess.

James an intake manifold and header setup that will show dollar to hp ratio gains that significantly beat what is being offered now will be worth every penny and I'll be on the top of the list for buyers!

It seems some are really finding that there is a great restriction in the intake manifold, open it up and optimize it and the makers will probably sell quick but if it doesn't show much of a difference from what some are already doing for practically free besides there own time than the seller will probably start to see cob webs growing in and around there newly designed manifolds, "We would hate to make a bad name witht the aftermarket guru's!"

Oh by the way I am refering to SVT's!!!

Here is the SVT manifold comparison dyno chart, a la my SVT. '00 SVT intake manifolds versus '98.5 intake manifolds. All numbers are SAE corrected and measured at the wheels. Please keep in mind that the SVT is quite modified and the numbers may not reflect as high a gain as would be possible on a vehicle with less modifications.



Here is the chart of the MSDS headers on our SE before and after the header install. All numbers are SAE corrected and measured at the wheels. Please keep in mind that the SE is quite modified and the numbers may not reflect as high a gain as would be possible on a vehicle with less modifications.

Chris,

We could dyno my car before and after the dual honed intake...

I'm doing some checking on other stuff before the install, but I'll let you know when I'm ready to do the swap. If you want to run the comparison on the same day I'll need a heated shop and a 1/4" torque wrench to finish the job (mine is 3/4" and too "heavy" for the gaskets).

If you want to run the dynos on separate days, let me know...

New cylinder heads?
