New Vortech Dyno

[stealthex]

Here's the before and after dyno for my friend's Si. He had AEM CAI, DC 4-2-1, Dunk knock-off axle-back.



Vortech vs. JRSC

[Rboosted717]

I compaired my dyno runs to his chart earlier today while I was at DSR doing some crap for M3's. Anyway I was around 10-15whp above his whp line all the way till VTEC kicked in. After that his line was about 10-15whp above mine to redline. Not bad at all! He's running probally around 7-8psi where I'm running stock 5psi. Hopefully if all goes well, I'll try a CRV pulley later on to match his boost to see what happens.

The crossing point is 5252 RPM. The formula is:

HP = Torque * RPM / 5252

The reason that the curves don't cross there is the offset in the scales (HP on left, torque on right). If you look at 5252, both readings are @90 (blue) and @125 (red).

The difference between having knowledge and applying knowledge is you cannot gain experience just from having it.

Maybe its just me, but I thought that the hp and torque curves were suppose to cross at around 5500 rpm because hp is actually a function of torque(don't remember the formula). Other than that, the plot looks nice, 235 is a nice healthy number, what kind of boost is he running?

It looks as if the JRSC has the slight advantage right until vtec.

They cross at a different rpm because the scale for torque and hp are different. We're assuming it's boosting at the stock 8 psi. No pretty boost gauge yet .

Call me crazy, but i think the torque curve of the JRSC is more ideal.

Also, to be fair the boost should be the same, otherwise its like hitting a nail with a 5 lb hammer, and hitting same nail with 1.5lb hammer and shouting, "look how much harder that 5lb hammer hits!"

there are many inefficiencies in the JR kit, so it is easily improved upon. Endyn has seen 20% power increase in high boost just from pointing the blower at the intake valves instead of the 90 degree angle JR uses.

i like my low end torque AND high end hp. In real life I live 2000-5000 rpm. So don't take any of that away from me, m'kay!
