Stock power curve
Does anyone have a link or pic of a stock FD power curve? I just haven't seen one yet.

Jim, do you know where one could obtain an .xls or .csv of that data?
Thanks :) |
What is done to the "modified" FD?

Here is are couple dyno runs the original owner did on my car.
Total mods he did were Pettit Intake, Pettit underdrive pulleys, Pettit/Borla catback. I think some of the dyno description labels are incorrect. http://www.verdieck.com/RX7/dyno1.jpg http://www.verdieck.com/RX7/dyno2.jpg |

My RX is only mildly modified power-wise (intake, catback, downpipe, M2 stage 2 chip, and pulley), but my dyno chart has the same pattern as Brooks Weisblat's car... is that normal? I had assumed it was....

Just saw this thread. Here are two things to look at.
This one is something I found on here a long time ago, done on some kind of chassis dyno (doesn't look like dynojet). It compares what I believe is a bone stock FD to some unnamed single turbo setup. https://www.rx7club.com/attachment.p...1&d=1348451646 this one was published by Mazda, using smoothed engine dyno data (comparing series 5 T2 engine with series 6 FD engine) https://www.rx7club.com/attachment.p...1&d=1348451646 |
great. I know the legendary Arghx will replay sometime. haha. thanks bud.
When I did my dyno at Corksport, they couldn't get the graph right that has the rpm on X axis so they went ahead and made a graph of HP and Torque vs speed (mph). I know my turbo trasitions late at around 5500 rpm so I was trying to confirm that on a dyno but too bad it didn't work out that way. |
Glad I could be of assistance. The inductive clamp used to for rpm signal is tricky to get right sometimes.
|
I thought the hp and torque curves should always cross at 5500 rpm but the stock FD vs single graph u attached show that they cross before 5500 rpm hummm.

When using metric units, usually kW and Nm, they won't cross like that. |
That's right, its 5252. For some reason I had the number 5500 stuck in my head maybe because my turbos transition at 5500 instead of 4500. I will post my dyno graph next week that I did at corksport on their dyno dynamics. Everything on car is stock except for radiator and RB cat back but I got 240 whp, makes me hard to believe.
|
I am trying to compare my dyno w a healthy stock FD to see at what rpm range my car behaves differently and from there to see if I can find out what is malfunctioning that's causing the late turbos transition. I can't feel the 2nd turbos kick in either.
