Dynosheet. I want some input!!!

Casey370z · 04-28-2016, 02:15 PM

Hey guys I am posting my recent dyno results and I want to know what you guys think about it.

Current Mods are Stillen G3 Intakes, Stillen UnderDrive Pulley, Fast Intentions Long Tube Headers, Fast Intentions Exhaust, Z1 Upper Intake Manifold and Lower Mantifold. I make 321WHP

Previously I had Z1 Headers and Stock Low Intake Mantifold (with the current list of mods ^) I made 329 WHP.

its clear after the LTH and Lower Mantifold change that i gained throughout the mid range however is it worth the loss i took at the High end? Please let me know what you guys think.

totally, how often do you hit 7K rpm?

12nismo · 04-28-2016, 02:33 PM

^ Exactly. IMO its absolutely worth a minor loss up top to gain more midrange. If you look at your dyno, you only lost power for the last 1,000 rpms and gained almost everywhere else, not to mention your bump in peak torque. Too many people get caught up in peak HP when midrange is where you feel/experience the power the most. This is the exact reason that I went for longtubes over the Z1 shortys. If you were to race your car now vs your car with the z1 shotys, your car now would walk away. Enjoy those longtubes!

What was the weather conditions between the 2 dyno runs?

Probably at most 5 degrees difference. Same California weather

Well considering that you are in the midrange more often than near the rev limiter, I would say that it is worth it. That is merely my opinion though.

Who Drive's their Z without hitting 7k on a daily basis?
Mine shift's @7500 leaving in "Drift"

Did you do a gear swap if Diff? lower gearing will reduce number's on dyno,,,Most accurate number's are in 1:1 trans. gear-even though some shop's don't like to see their Dyno spun up over 175mph.

No i did not change anything in regards to diff/gearing. Usually when i dyno on a Dynojet i Do 5th gear. however for some reason on a Dynapack 5th gear reads lower than 4th gear. so these graphs are from a Dynapack.

Maddog · 05-02-2016, 08:00 AM

Dynapacks read hub not wheel horsepower although thats similar to dynojet whp

Would agree with the others here, the mid range gain is worth it, we don't drive in the 7k range
