ok here is my 88 trans am gta with a mildly built street motor... it has a crane 2032 cam with many other mods listed in the info on youtube.... i was surprised that the cam sounded so mean... it sounds meaner in person.... to me it does not sound stock at all...... everyone tell me what you think of my ride.. thanks.....

That does sound pretty mean, a littly lopey, I like it.

 

thank you.... i get looks everytime i drive the car.... what really helped the idle was the heated 02 sensor and adjusting the fuel with a afpr..... my next project this winter is gonna be a set of afr 180cc and the hotcam and a rebuilt 355 l98.....

 

88fastgta, your car sounds good! What wire did you tap into for powering the heated 02?

 

sounds similar to my car, same cam only with shorties, no cat and an open borla.

 

we tapped into the fuel pump relay underneath the car.... that way the 02 sensor is off when the ignition is off and is on when the ignition is on..... then when put the ground wire underneath the car i forgot where exactly but near the rear tires.... it didnt lope nearly as much before the heated o2 sensor now within 30 secs to a min it has a mild lope... sounds a little more choppier once in gear...... love the cam....

 

How do ya figure it's got 400 Hp with a upgraded TPI, ported L98 heads and small lift cam?
Have you dyno'd the car or run it down the quarter.....?

I watched your youtube video's & I gotta give it to ya it does sound lopey ...... but throwing Big #'s around can appear foolish.

4oo Hp would get you a 12 second 1/4 mile @ 113.5 Mph (Estimated @ the wheels) Which is not all that easy to do.... (normally aspirated, that is...) Check out some of the Horsepower calculators out there......

The ET method
This method uses the weight of the car and the time it took that car to travel 1330 feet (¼ mile).

The formula is: hp = weight / (ET / 5.825)3

The Trap-speed method
This method uses the weight of the car and the speed at which the car completed the quarter-mile run.

The formula is: hp = weight * (speed / 234)3

Not to insult you but I was wondering/noticed the same thing

 

it was supposed to be 300 hundred not 400.... i just haven't changed it yet.... but yeah it does sound lopey... it will change it later today...
