car: 81
motor: 89 13b turbo
turbo: Garrett T04B
A/R: 1.32 rear, .70 front
Ported: Yes
Fuel system: Microtech computer, 4x1200cc
Power: dynodynamics. 11psi 310rwhp, 19psi 407rwhp, dynojet, 11psi approx 370rwhp, 19psi approx 490rwhp
1/4 Mile, 10.93@124mph

 

Why such a big discrepancy between the dynojet readings and the dynodynamics readings? Which one is more accurate?

 

approximatly the car is loosing 20% thru the drive train. the dyno dynamics dyno systems read 27% loss from the flywheel, so they are reading 7% less than actual HP at the wheels, while the dyno jet system is reading 15% loss from the flywheel so it is reading 5% higher than actually HP at the wheel.
make sense? i hope so

 

Understood. Thanks!
