driveshaft dynoed

[Go4broke]

I got my car dynoed today. my old dyno sheet read 156.1hp at 193.1 torque. My new dyno reads 159.6hp at 196.5 torque. this time I did three runs. a new speed shop opened the new dyno jet tester $44 for three runs not to bad. both dynos are on my cardomain site. http://members.cardomain.com/phatrabbit

i guess he got a new driveshaft... aluminum or one piece steel?

[MrCoffee]

thats cool, I didnt think driveshafts did that much

[Go4broke]

sorry I got a one peice driveshaft 1LE aluminum, I had a 2 peice before.

[JML97-3.8]

Cool, I just put in a 1Le I could tell a diff... But its good to see some numbers.

[SlimJim1284]

doesn't seem like alot of horsepower for all those mods. i got 166 from just a lid and cai

[Go4broke]

thats what I keep saying but everyone else said that it sounds to be about right

3.5 hp and 3.4 tq gain doesn't sound too great. That's a 2.24% increase in hp and a 1.76% tq increase. I'm sure if u'd done more mods to the car, you'll see and even bigger gain in hp and tq, but the % gain would be the same. so say u made 200 rwhp on a 2-piece, and then u switched to a 1LE, you'd gain 4.48 rwhp. doesn't see like much of a mod until you have done other modifications to your motor. Like shirl, she'll probly see a decent gain from 1LE since she's already pushin out a lot more hp than stock while using the 2-piece.

why is your dyno reading say 159hp and u have a 1998 3.8 I thought it was 200hp stock?

[Wicked 3800 V6]

95 Firebird, that's HP to the rear wheels, and the 200 is rated at the flywheel.
And Go4Broke, is everything running OK? Fuel filter, plugs, wires, etc.? Good but low numbers.

[Go4broke]

fuel filter, wires, oil, plugs are new. SES light is on code P0420 that might have something to do with it, other than that all I can think of to change is my coil packs. Is there anything else I should look to see if that might be the problem?

[1998silverbird]

Those numbers do seem kind of low for you dyno.. are you sure the dyno is acurate?? Now I am not sure if I want to get my car dynoed!! That 159hp sounds like stock numbers to me.. Look up that code the cpu is throwing at you..
