Headers Feeler - Page 2

Might be interested depending on price.

Like I was sayin before that is the idea I have in my head, I need to go over the flow of them, and consider whether I would be able to get away with a universal design for FI and NA or not, I was just feeling the interest in headers. I know for a fact that longer headers are better for NA however I was trying to make it easier for people to switch out with a almost stock replacement header.

I appreciate all the feedback I definitely started this thread just for that reason. I'm trying to gauge the market and see what the average SVXer would prefer. We all know just about anything is better than the oem design. However before I dump money into producing a product I'd like to see what things are most important to the SVXers.

So keep the comments and ideas coming. as far as bungs for EGT and Wideband, you can count on those. I'm just trying to determine if it's worthwhile for me to produce NA headers or not. and the longer this goes on the more I am encouraged to do so.

POWAAAHHHH.

I would like more low-end torque. I will probably be staying NA.
I will eventually be replacing the entire exhaust system.

John, I think you are definitely going to need to make different setups based on N/A or F/I

I just want to let you know there were two reasons why I always did headers as one-off designs

-They are always application specific
- The cost of mass production outweighs the demand

Think about it

ya I'm thinkin about it more and more it's tough to do one design that works for everyone, I'll play with numbers and see if there is something I can offer as a NA option, more later.

Just make one for N/A, that someone with a stock SVX could use and put an aftermarket exhaust on. That'd be your biggest 'seller' if you could sell any.

How wildly would the designs differ anyway between NA and FI?

in reality, they should be nothing alike.

A single set would cost over $400 for the individual consumer, but a set of 10 or more could probably be had for a significant savings.

Not trying to hurt business, just trying to save in startup costs and offering ideas. I'm pretty new to the community, so I don't know if this has been offered as a solution yet.

I believe that the Extrude Hone system just polishes/smooths the inlets and the outlet of the factory header.
Its more of a port match than a real system.

Believe it or not FI or NA does not make a differance in header design.
Its all about cam design.
When I learned this I was both shocked and doubtful, but this is what I have learned, and now believe.

and you will demonstrate as soon as you can get a couple of those SVXi fixed and out of your yard, right?

honestly right now I'm in a tough situation money wise, my priorities for the SVX are CAI after its back together and has the suspension in, then maybe full poly bushings and a group N Tranny mounts and a stiffer pitch stop mount, possibly some brake upgrades and more custom suspension parts, then engine build and turbo kit... sometime if I have time I will try and figure out some NA headers, if I can make an easy almost bolt up setup I will. Chances are it will be for aftermarket catback exhaust as well. I may decide to do a full headerback exhaust kit instead not sure. Honestly its up in the air right now.

Only real issue is where peak torque is desired, The design is effectively the same, the lengths, collectors, and tube diameters are always the variables. There is also the consideration of materials used and their capacity to retain heat. It is not as simple as slapping some pipes together and saying.... well thats worth at least 20 hp
