I wanna know how much horsepower my brothers 95 z28 has stock
and with a borla exhaust and a moroso intake. He also has a after market computer chip but I am not sure what brand it is so I am not gonna bother asking how much horsepower it puts out. I have looked for days online to find the horsepower gains with these mods but I have come up empty. If anyone knows I greatly appreciate any info you may have.

 

Everytime somebody asks how much power their mods are adding, I have to go out and fire up my SWAG calculator. 310 HP at the flywheel +- 10%.

 

Stock Horsepower is 275, and torque is 325. Moroso claims +20 horsepower, my hypertech chip claims +15hp/15tq i think. The exhaust im not sure.

 

The problem is that you can't add all the claimed HP increases toghether and come up with a realistic result. As an example, if you have a CAI that claims 15 HP and a chip that also claims 15 HP, when you add them toghether it most likely be less than the 30 HP expected. Conversely, if you have the same CAI and now you add a cam that claims 30HP, the two willprobably complement each other, and the final output may be more than the suggested 45 HP. This is the reason that parts have to be matched properly, so that they complement each other.
