Vr38dett Engine Dyno!!!

[christx]

This is on an engine dyno. As a far as each being different, I dont buy that. If they are assembled by hand using the same specs how much difference can there be? probably more consistent then machines doing it.

Have all the dyno results you've seen been on the same dyno, same octane, same elevation, same weather etc? There are lots of factors that are in play.....

Dyno results from different areas should not be used for hp/trq comparisons, it's not accurate. HP/trq numbers don't mean anything, trap speeds do. Unless you are looking to be a number queen and still run 15's

Remember, dynojets, dynapacks, dynodynamics, mustangs etc. all read differently, this is widely known....

My engine leaps around like its possessed- especially when i switch it off and it decides to run on/hesitantly stop.

Is the only option new nissan mounts?

Yep

apparently its only by a few hp my guess would be not enough to notice

torque is a factor of dispacement and boost pressure.

horsepower is a factor of torque x RPM.

if you want to make more torque than horsepower, limit RPM's, or run small turbos that make lots of torque and not lots of horsepower.

the RB26 is a small displacement, high revving motor. Add displacement or take away revs and you'll see similarly matched numbers.

Sort of right,

Torque is a factor of Force x Distance, nothing to do with boost pressure, although it may increase relatively. Measuring torque is done by adiobatic compression which is change of pressure relative to volume (simplified version)

Power For Imperial or US customary units Horsepower is a factor of
[RPM * Torque (inch-lbs)]/63000

Power For SI (metric) Units
Power (KW) = {[(RPM*2pi)/60s]*Torque(N-m)}

For US customary units/ Imperial Boost pressure is relative to Force (usually measured in lbs) / Area
Or, Pressure = (roh looks like a P)(g)(h) when discussing fluids.
Where P is the density of the fluid relative to water (1.94 lb/ft^3)
G is the force of gravity (32.2ft/s^2)
H is the change in displacement of the fluid.
This will give you Lbs/ft^2, so to convert to psi multiply by 12^2 (inches squared)

your boost gauge works on this principle by tapping into the system to see how far it moves fluid through a pipe.
Enjoy, you're now qualified mechanical engineers.
