I have tried twice to dyno my car, once at the RX7 revolution and again at the RX7 store, and both times the dyno computer would shut down in the middle of the pull. These were on 2 seperate dynos, one Dynojet and another Mustang. Both the dyno engineers were baffled by this and couldn't do anything about it and my car was the only one it happened to. WTF??
Can anyone shed some light on what is going on.

BTW I dynoed at 337rwhp at 4700rpm which is where the dyno shut down each time. That is well before my motor really comes alive.

 

Bump

 

thats pretty good power. those stockers? unsequential?

 

Too much power for the dyno. Computer go "poof" and pour out smoke.

 

337 rwhp sounds about right for your 1/4 mile time of 12.6. Was that run made before a few of your latest mods?

 

yeah i ran 12.5 with about 290...what gives?

 

Yeah this is on stockers, but thats 337 at 4700rpm. That is before my powerband, but where the dyno stopped recording.

 

He made 337 under 5000rpms!!

337 rwhp is more like a 12 flat-high 11 second pass if u get a good 60 time. However u really shouldnt use ET to make a conclusion about someones rwhp as ET is way too dependant on drivers skill. Compare someones trap speed to get a good indication on rwhp. Having said that, i think u are making 360s rwhp.

 

thats weird that it happened on 2 different dynos.
.. Bad Grounding points maybe?

 

337 rwhp on the first turbo is impossible - even running non-seq with your mods I can't see that much power before your power comes on - that would translate to 500 rwhp on your second turbo by 7500-8000 rpms - are you sure you're not reading your torque curve? That would be more believable. I made about 200-210 rwhp before transition and topped out at 380 rwhp at 15 psi running BNR 2s sequentially - artguy made over 210 rwhp right before transition and topped out at 381 rwhp at 17 psi with the M2s - I remember reading that you are sequential - I know your car is fast - but not quite that fast

 

that would be nice to have too much power for the dyno

 

Ryan,

Before you start the car, push down on the gas pedal, the brake and turn the AC on. That will wipe out my last map on your car. Then, you can dyno at will!

I believe 4700 is just after the second turbo kicks in, and when my second comes online it is comes on hard.

 

I can see 337 rwhp by 5500 rpms but impossible in sequential form by 4700 rpms. My second turbo kicked on extremely hard also but I know that you aren't making more than 100 more rwhp than my car was at the same rpm when I had upgraded twins, streetport and topped out at 380 rwhp at 15 psi. Not trying to rain on your parade - just saying that it's impossible.
