Interesting, I was always under the impression that gearing played no part in actual power output. I figured that stuff Toyota would of fix most of the leaks.

I'm almost done with my car save for the motor, so I'll be contacting you over summer to talk about tuning and motor setup.

 

tourque directly relates to the "radius" of the gear, and horsepower directly relates with torque. so yes, the gears, and wheel/tires will make a difference

 

except when its just put on the outside of the leak area hahaha.
although it does work sometimes...

 

replaced my 20 year old fuel pump with a 255lph unit, as well as got some basic runs on the Dyno, 400whp, 350wtq @ 1.2 bar with stock 440 injectors on the POwer FC.


looking for some 550`s and a fuel pressure regulator.

Nice try. Dynojets directly measure power at the wheels. They then back calculate against the RPM of the motor. On something like a dynapack that measures torque at the wheels directly, this is true. That's why they make you punch in the overall gear ratio so the computer can divide it out, then back calculate HP.

Horsepower at the wheels is independant of gear ratio or tire diameter. The pitfall of your logic is the 3rd term in the tq-hp equation. That's rpm. If you jack up the wheel torque with a higher final, you're also spinning that wheel faster per engine rpm. The 2 factors are equal and cancel out.

 

^^ joining us today is professor epstein on his reading of dyno physics

 

I received my title and my new temp sensor in the mail

 

The last statement holds true on a manual transmission. However, when dealing with a vehicle with a high stalled automatic (say 3500-4000 and above), the curves and results are very skewed. Unless the dyno can pre-load the vehicle, the stall can and will continue to slip aggressively causing the actual power numbers to read lower than they actually are.

Might want to ask the LS1 F-body guys about this one, it happens to them quite frequently.

 

Anyway, I gave the two 240s a new place to sleep:



Finally cleaned out the garage, it was a 1 car garage for the past 3 years.
