Message I know some of you have been waiting and waiting, and waiting....well so was I. We dynoed my new car car today, and all we changed to the moto/driveline were the new Inconel Headers.

This first graph shows my last run when I had the red 1SLOWZ w/ PORTED stock exhaust manifolds and having the car TUNED (#5). Run 6 is just slapping on the new headers and dynoing...NO tuning NO messing w/ anything.

So here are the different points over 100 rpm increments of run 5 and 6. The first one shows all the points for run 5, the second one underneath is for run 6. Again this is just putting on new headers, NO tuning. Compare and see for yourself at each RPM.

OK now here are the results when we tuned the car for the headers. This is for all the big turbo braggers! I got more band than you! No pun inteneded Zo!

Here are the 100 RPM increments w/ the tuned run. Compare if you wish.

From DD the car, I see an improvement in EGT temperature by at least 100 degrees celsius. Gas mileage is actually better, no kidding. Response is WAY better and I can't keep my BF Drag Radials sticking!

Here's what you guys want to know. When and how much?

When: At least another month or 2. The car is gonna see alot of abuse. Drag events every weekend not to mention causal street events.

How Much: Somewhere around $1800.....too much? Consider that Inconel is an exotic metal and it's cost is 10x greater, and alot harder to work with than regular stainless steel.
