RX8 Dyno

WE3RX7 · 11-14-2009, 09:53 AM

Typically the dynojets will yield slightly higher numbers than a mustang dyno. Some people say tuning on a mustang dyno is better and more accurate.

The more important factor IMHO is that you use the same dyno throughout the build. This way you know your gains are accurate even if the equipment isnt and your not introducing a different variable into your tuning.

Also, find a good shop. I have dealt with some pretty bad dyno shops and it took a while to find one I liked and trusted.

Would anyone say the RX-8 poses any special requirements for a dyno? THe reason I ask is because I would think the rotary would have a harder time spinning up the drum (low torque) and then showing its best at the high RPM when the HP comes on. I have also noted bigger than expected differences between stock engines - peaking at 8000 rpm vs still pulling when the throttle is cut.

I am hoping to dyno it before mods and then dyno each change - probably engine management first.
