Tale of Three Dyno's
This is the tale of three little Dyno’s - - a DynoJet - a DynoDynamics - and a Superflow WinDyn
I thought I would share my “Dyno” experiences with the forum. I know some members have been elated with their dyno results, some perplexed and some down-right disappointed. I’ve had my SRT6 on three different dyno’s now and have pieced together some info that might be useful to others. Those with more experience or insight - feel free to add...
Basically what brought this all about was a visit to a dyno shop last night for few runs. I figured I was pretty much done with performance mods for a while and I knew SRT6 Dan had used this local shop and posted his stock SRT6 results on the forum. I figured it might make for a good reference for me. Also, other forum members have asked me for dyno results to help them with their mods so I thought - - let’s do this now. This turned out to be one interesting evening.
I had called and made an appointment at BBR (they are not an everyday shop – in fact the space is just used as a hobby shop by the owner and he only does dyno’s three evenings a week and on Sat by appointment) No sooner was my SRT being setup on the dyno when Code3 himself pulled up -- Well OK I thought – I guess he made the hour + drive down to see the “competitor’s pulley” run. I’ll admit that I was a little evasive at first – I just wanted this to be my time on the dyno and not to try and “measure up” but soon opened up about my mods – but as the night went on …..
Let’s leave it there for now and have a look at some older dyno charts. Sometimes they speak louder then words….
Below is my first Dyno after I purchased my SRT – not knowing what to expect or how to ask for proper graphs – it turns out that Andy at the Corvette shop that opened up his dyno to me (he pretty much just uses his DynoJet to tune the performance mods he installs for Corvettes (650+ HP modded Vettes that is…) I though it might be useful here because I returned to him today…. But let’s go on… this the proper way to set up a customers dyno graph. The same parameters for HP and Torque on both sides and engine RPM on the bottom. I didn’t ask for this; Andy just knew. I did not ask for AFR because I didn’t know, but that’s all part of the Dyno education. 267.5 WHP and 263 Torque: Notice how the Torque curve is high above the HP curve until they interest. Keep this in mind.

Here is dyno pull #1 on a DynoDynamics @ Gintani/Speed Innovations after I had installed the SL55 intake, 185mm Pulley and Iridium Plugs prior to the tune. The AFR was 10.5 – 11.0. This graph was poorly setup because the Power and Torque references differ on each side and the bottom should be displaying engine RPM – This was my fault - You need to make sure you ask the operator to set up your charts correctly - you may want to a printout that is different then what they need to see.
Next is a screen-shot of the Power-Torque-RPM website that converts these DynoDynamic numbers to DynoJet numbers – this comes into play later when we see just how accurate all this is…..
