It's time to have a little fun.
I wanted to know how well the Harrop TVS would perform on the street and what it would take to get equal performance from a centrifugal supercharger. So I fired up CarTest to see how the Harrop would perform, then I went to the Dyno Database to find a dyno that would give equal performance. I think I found a pretty good match (it took a few tries). According to CarTest, these are about as equal as I could make them. The Harrop slightly outperforms on the 60-130 by 0.10 second, while the ESS 625 I used outperforms on the 1/4 mile by 0.10 MPH and 0.18 second. I'd call that pretty equal and looks like I found a good comparison. To visually see what that looks like on the dyno charts, here's the dyno of each kit that gives equal performance. Finally, here's the CarTest results that show equal "street" performance based on these dyno charts above. Interesting to say the least. 1.

Based on your data, i'm impressed with this kit! With less hp and less boost (im assuming?) it appears to have more "area under the curve" then the centrifugal SC. If we had a dyno that showed the TVS to redline (i'm assuming it goes more than 8100) then it can even be more impressive imo. The drivability of the TVS has to be pretty good based on your comparison.

I do drive a similar setup every day in the CTS-V, and it's quite nice. Makes power differently for sure, but quite nice nonetheless. |

"Ive got nothing to do with it" or some variation of that, is vastly different than "Im not at liberty to discuss"
#hujan - Im confused on your comment, mine has a REAL application here; dont you have more butt dynos and "+1's" to post and review with..? |

IN-4-UPDATES.
Max torque at 5.3K RPM looks very good. Torque falling off at higher RPM is expected for this type of kit. After the tuning dust settles I hope peak power stays near 8K. Will this car be ready for Bimmerfest-2014 happening next month? Are we going to see the finished product by then? I still remember their head research guy from about a year ago saying that their plan was to get this kit out in the fall of 2013. Why is it taking so dam long and why are they not reporting their progress directly on this forum instead of getting 3rd-party comments? I hope they realize that this is where their future customers will likely come from. Last edited by Top_Gear; 04-13-2014 at 03:36 PM.. |

Since this a positive displacement supercharger (Eaton TVS), the manifold pressure readings are a measure of the engine's efficiency (or inefficiency). The more inefficient the engine, the more boost will be achieved at the same blower RPM, and less HP/TQ. If, for example, the blower RPM is maxed out on this application and the S65 is only generating 6psi of manifold pressure, that is excellent!. That means the engine is consuming the extra air (re: oxygen) and making very efficient power. If, at the same blower RPM, the S65 was generating 10psi of manifold pressure, the horsepower would be lower, as the extra air is turning into pressure, and not being consumed.

Loving the stories - ie old info from months ago dated as new; and engine theory.. Would be a shame for them to oversell and under-deliver. Lets just wait and see what some 3rd parties can pull out with it
