  • Dyno Results

    I am on the charts to be emailed to me, to post them, I have no scanner so I can't scan them in. Best run was 349.42 hp, and 348.35 tq. This is at the wheels, so could someone with the majic number game tell me what is that at the flywheel?

    It also says.. run conditions, 76.02f, 25.44- in-HG, Humidty 43%, SAE 1.2

    Looking at it, it peaked at 5600rpms for hp, 4800rpms for tq.

    Now the 3rd run, which i don't count because the belt some how came off, produced 366 hp and 424 tq. The first and second runs were right comparable, with the best being the 1st. 2nd run was 348.94 hp, and 346.15 tq.

    Now all i have to do is get the power to the ground!

    What trans - A4 or M6? Can't estimate flywheel without knowing the trans type. Stock 10-bolt?

    Where did you dyno? That barometer/SAE correction appears to be what you would see at elevations in excess of 5,000-ft e.g. Denver. Doesn't seem conisistant with Ft. Bragg, NC.

      A4, stock rear end, and yes it was right outside of bragg in hopemills. The paper says dynojet, winpep7, dynojet performance evaluation program. If you need to know that too..

        Given the actual barometer reading, that is approximately a 4,500 ft above sea level reading and the 1.2 SAE correction factor is about right. I didn't realize the elevation was so high around Ft. Bragg.

        Very good numbers to the tire given your mods.

        Generally speaking, the drivetrain loss is right around 17.0%- 17.5% through the A4 and 10 bolt. So you're making approximately 420-425 HP at the crank.

          I like that number.

            I hate to even mention these things, because I get accused of being "negative" and trying to bring people down - that is not my objective, just trying to understand the numbers. Hope Mills, NC is at an elevation of 109-feet. The SAE correction for temp, humidity, and barometer works out correctly from the numbers shown. I just don't understand how the barometer could be that low.

              And all you have done is a lid, MAF porting and exhaust? Wow.

                I remember reading on here how some were LS1's were built better than others, so would that be a considering factor? The motor only has around 8 thousand on it too.

                  I have the charts emailed to me, as a *.drf file. What program do i need to open these?

                    Those numbers do seem really high given the mods - especially since it as a 98. Maybe you did get a factory freak - that would be cool! Maybe it's the reverse indiglo gauges
