Contour Enthusiasts Group Archives Forums General Dyno and Drag My SE Dyno run

My first dyno was this past spring with the Extrude Honed upper intake, SVT exhaust, KKM, and strait inlet pipe. My best run was 133.4 hp with a very flat torgue curve around the same numbers. I dynod again Sat. with the SHO Shop y-pipe and 60mm TB. This time I ran 142.8. So I gained 9hp with the SHO-Shop y-pipe and 60mm SVT TB. I lost some at the bottom end but gained above 4.5g's. I think I will switch back to the 55mm TB for the low power. I can feel the difference between the two TB's though. The car begin's to take off like a turbo. Slow at first then wham here we go. I think for better drivability I'll put the 55mm back on. I was the only one that day to show gains because I went first when the everything was pretty cool outside. The dyno was corrected for everything but humidity. I think the y-pipe made most of the difference in power. I know the conditions would worsen so I'm glad I opted to go first. I'll let Mark and Steve comment on their pulls. I know they were not too happy and swear the dyno didn't show what they felt in their seat pants.

I would think the 60 tb would work great with a chip and a bigger MAF. Especially with the SVT intake setup. You should see 150+ hp.

You should be seeing a lot more then that! When I dynoed my stock 96 SE I got 152hp and 153ft/lb at the wheels.

Maybe redracer. It seems that dynos seem to be different everywhere. I know my car has 107k on it so this might be due to being a bit tired. It was kind of humid but not as humid as the conditions as the other guys had. I know I made 9 hp so no matter what my true numbers are I'm dynoing on the same machine so that I can see the true benefits of my mods.

Anyone ever dyno an ATX Duratec?

Actually, back in late 99, we had a customer dyno his ATX Duratec Contour. His numbers showed, IIRC, around 128hp at the wheels. I don't remember the torque figures though. He only had a KKM at the time.

Christopher -- so only about a 20hp drivetrain loss? Not bad IMHO....here's something interesting on that:

My car has the KKM & no res exhaust. I raced an MTX Cougar w/KKM & Borla exhaust. They launched well, as did I. She ran only 0.2 sec faster than me!

So I guess with some basic mods (KKM, exhaust, etc) an ATX could keep up with a stock MTX?!

128 dyno HP + 20 hp lost to the drivetrain = 170 dyno HP. That's pretty cool.

Welcome to first grade, ladies and gentleman.

Oh sorry, my bad. I meant about a 20hp loss from the 170hp rating to the dynoed 150ish.

ContourGuy,

I saw two 3 ATX V6 Cougar's dynoed. One had a weapon-R intake, Apexi exhaust, and an UD pulley. It made a 123hp. Another had a Borla, KKM, and MSDS headers and made 135hp. Mine with a Borla, Custom intake, MSDS headers and the IAT mod made 151.5. The driveline loss is estimated at 30%.
