Well the torque curve is like this.
1500 @ 100 2000 @ 111.5 3000 @ 194 4000 @ 204.4 4500 @ 195 5000 @ 185 5500 @ 175 6000 @ 150 The HP and Torque curve cross at about 5250 RPM (like what you said Donnie) HP is like this. 1500 @ 30 2000 @ 41.9 3000 @ 115 4000 @ 155 4500 @ 165 5000 @ 177 5500 @ 181.6 6000 @ 175 So after 6000.....things start to go downhill. BTW, this dyno didn't measure tranny loss. Well, let me know what you think.....I'm still going to post the graphs later on..... I love how the TQ jumps all the way to almost 200 at just 3000 RPM's and stays right up there until it crosses with the HP curve. Makes for nice acceleration. Also here is the deal.......we messed with the little screw behind the air flow meter and richened the mixture up a little bit to 11.9:1 while under boost. Well, we noticed on the dyno that we lost about 11HP and 12 ft/lb with the mixture richened up. So, I wasn't going to do that.........we leaned it back up to 13:1 under boost. This is where I got the best power numbers. Well, what do you think I should do? b/c when the boost kicks in....that piggy back fuel computer that Mosselman sent me richens the mixture when boost pressure is sensed.....however, it richens it up too much to where I'm not getting the best mixture while under boost. I guess I need to contact Mosselman to see if I can adjust the fuel computer while it is boosting......that way I can lean it out just a tad. OR maybe I can invest in a more powerful ignition system....that way I can use that extra fuel for more power. OR maybe I can turn up the boost and lean it out that way??? HMMMMM........I just want some opinions.....thank you. Jim....that is great!! My HP and torque curves look almost identical to yours.......mine are just a tad bit higher  Seems like your car is coming along great! Well, keep in touch. Later.
