Tonight I dyno'ed my car with Random Technology High Flow Cats and Nismo Exhaust.
****** I AM GETTING A REPRINT OF THIS DYNO, IF YOU NOTICE IT IS NOT SCALED! ******
I had my dyno pull after driving for an hour to get to Powertrain Dynamics. Talked for a while with a guy from down the row of shops. Laughing about things people came in with attached to their car's to try and make power. The funniest thing was a WEED WACKER as a blower! :P
Any way to the point of this. MY DYNO!
My car was warm from driving for an hour, out side temp was similar to the previous DYNO. On the same DYNO
Car Details;
What year your Z is? = 2003 purchased April
How many miles was on her? = At time of Dyno 19800
NA, Super Charged or TT? = NA (for now)
Auto or manual? = Manual
What was the name of the place you dynoed at? = Powertrain Dynamics
What psi did you dyno at if your a Super Charge ot TT? = 1psi Weed Wacker Motor (j/k)
What gear your pull was made? = 5th and ALL PULLS for 6MT should be in 5th the only 1:1 gearing. Auto's in 4th the only 1:1 gear in auto.
What modifications were done when you made your pulls? = Baseline only
NISMO EXHAUST and next mod was with the addition of only
RT High Flow Cats
And of coures a picture of your dyno sheet? = See Below
Previous DYNO 11/01/03 =
NISMO Cat Back Exhaust
Latest DYNO 11/18/03 =
NISMO Cat Back Exhaust &
Random Technology High Flow Cat's
11-01-03 = 241.4 Actual RWHP / 231.3 Actual Torque (ft-lbs)
11-17-03 = 248.0 Actual RWHP / 239.3 Actual Torque (ft-lbs)
Gain = 6.6 RWHP / 8 Torque
I am VERY pleased with the Torque gain down low and how the gain is across the full span of the powerband. I loose TQ and HP on the 6400 mark faster then with only the exhaust. I am hoping an intake of some kind will fix that.
It took me over 3 hours to drive home so I dont exactly feel like bending over my car and putting in the K&N Typhoon.
So! Soon to come, Typhoon Install (tommorow) and Dyno of the Typhoon added to this.
Below is the Pre / Post DYNO sheet and link to a video of the Dyno pull where you can really hear the exhaust in action up to 140+ MPH!
