question regarding stock power..

[93v6firebird]

whats the stock ammount of power and torque to the rear wheels on a 3.4??
what is generally the power loss along the drivetrain?? I think its like 25 percent?? or is it more? thanks a lot!

I would guess 125hp at the wheels. My car pushed 170hp at the wheels when it was stock

I heard about 20% loss for a stick and 25% loss for a auto

well on the same day I had a friend G-tech both my 3.8 and my buddies 3.4

I got 174RWHP and he got 145RWHP (bone stock) on his 3.4. Was about 90F w/lots of humidity...hope this helps

99camaro99, what all mods did you have when you pulled that 174hp? I did a dyno pull with the FRA, K&N, MAF screen removed, PVC piece replacing the air silencer, Flowmaster, WS6 tailpipes, Bosch plugs and wires, and 91 octane gas with a bottle of Redline FI cleaner, and I pulled a best of 169rwhp. I don't know if my numbers are low, or about right for the mods that I have.
Also, how did you modify your cat? I'm wondering if I would get better gains doing that, or putting in a LS1 manifold to Y-pipe section.

He has a '98, it's a 3.8L V6. But you are right, stock on a 3.4L V6 is around 135hp at the wheels.
