Thanks for the info. Sorry, boss, didn't mean to make you have to type all that out, I just found it odd that you would put the completely stock TB on the '95, unless there was nothing to be gained or unless there was a disadvantage in doing so.

I await the results of the test cases.

I'm not trying to annoy you or anyone else but all this porting, polishing etc and the testing things (to me) seems to be aimed at the supercharged crowd, what about us Naturals? Surely we do can benefit from a ported TB, I'm just asking for the Naturals who'* nervous of asking you.

Fuel, There are many people, naturally aspirated, that find gains by optimized porting and polishing. Ultimately you want to do all the flow paths, starting with the items that are the most restrictive and going through the system like that until you've created a path of largest, smoothest flow that you can.

The essence of it can be explained by what you find when you remove the restrictions in your intake box and tube by either gutting and using a higher flowing K&N or equivalent filter or going with a rice pipe or FWI. You are increasing and smoothing out the flow.

To put it too simply, your engine is essentially a large air pump and the more air you can get to flow smoothly through it while still keeping a correct air/fuel ratio, the more power you can get from it. That is after all the general concept of both a supercharger and turbocharging.

I'm sure I'll get corrected for oversimplifying things that are much more involved than I've stated, but so be it...lol.

Yes, all car levels can benefit from polishing and cleaning up rough surfaces where they create drag etc. The level of noticable difference can be zero though. One may only notice the differences on a scan tool, similar to those of us with normal and performance shifting modes.

The SC crowd simply seems to be a little more proactive as they are already addicted to power and no longer understand the acronym MPG.

As well, BW working on his car and doing so provides a lot of information and data to us. Currently....he'* got two SC cars.

Fuel, keep in mind that I'm doing an L36 TB right now, too. Think about that.

Thanks guys. I know that the SC crowd get more power of the same mod (that does exist on the NA car such as TB, headers etc, not a SC pulley) and the Natural gets a small amount of hp out of it while the SC gets a impressive gain.

Also, thanks for explaining it more clearly.

I must have missed that you were doing a L36 TB or I never knew.

(psst, if you need a test car for that TB, just send it to me. ) Sorry I couldn't resist.

Test car was identified before I ever had the TB in my hands (same is true for the S2 L67 TB).

Crap, didn't hurt to ask, can I be the back up if the first one falls through?

Nope...

What'* up with the butt?


And to keep this topic on track, I'll be watching for results
