What is the difference between a Mustang dyno and a Dynojet?
What is the difference between a Mustang dyno and a Dynojet?
The load is simulated on the car via a hydraulic pump. Because these are effectively inertia-less, they will read HIGHER than the standard Dynojet numbers by 8-10%. That number will vary depending on how “fast” your dyno run lasts (sweep time), but as a rule of thumb, they’ll read ~8-10% higher.
Is a Dynojet accurate?
Dynojet. The inherent simplicity of the Dynojet system, with its fixed weight roller, non-adjustable load (on standard 224 systems) and simple mathematics, makes the Dynojet reliable, accurate, and, most importantly, repeatable from run to run and dyno to dyno.
How much power do you lose on a Mustang dyno?
You typically lose about 15% -% tugh the chassis, so 380 divided by . 85 = 447HP at the flywheel (basically 450HP). Now, with a “load” chassis dyno, you will typically have about 140 LESS power than you would with a “non-load” (inertia) type of dyno.
How much lower do Mustang dynos read?
Mustang Dynos can vary greatly, depending on the type of mustang dyno and how its setup. Some can read 5-10% lower and some can read lower.
Are dynos accurate?
about the accuracy of dynamometers, or dynos, as they’re most commonly called. The standard deviation for comparing the number retrieved from the dyno (horsepower at the wheels) and the manufacturer’s advertised horsepower (at the crank of the engine) is 15 percent to account for power lost through the drivetrain.
Is a dyno WHP?
Unlike bhp, whp is the power output measured at the wheels. This is the information a dyno run provides and usually reads around *15 per cent less than the power measured at the engine (bhp) – this is because power is lost in the driveline (including clutch and transmission).
How much HP does dyno add?
To give a ballpark figure – if you are on a stock car, you could probably gain 10-15 horsepower from a dyno tune. However, if you are running on performance parts like exhaust and turbo, then 50 horsepower gain is possible – even more depending on your engine and what performance parts you equip.
Does Weight Affect dyno numbers?
The weight of the wheel does change the way the Dyno shows your readings. I have been doing dynos since 1996. And have seen people actually swap out 18inch wheels with 15″ wheels just for the dyno, and the hp difference can be as high as 10 hp. Dynos work by measuring the acceleration of the drum.
What do dyno numbers mean?
Dynamometers are used all the time to measure power output for cars. The standard estimate for comparing wheel horsepower (the number retrieved from the dyno) to crank horsepower (the manufacturer’s claimed number) is a 15 percent difference. The first run was simply a baseline used to measure RPM readout.
How does a Dynojet compare to a Mustang Dyno?
You can’t compare it to ANY other dyno of a different brand or under different conditions. 560 rwhp on a Mustang dyno in the worst of conditions can mean that car is running MUCH stronger than 650 rwhp on a Dynojet in the best of conditions.
What is the most accurate Dyno Dyno?
Dyno Dynamics Dyno’s are one of the most accurate, followed by Mustang Dyno’s. 714 hp – 20% (roughly what I was told by SRT folks is the drivetrain losses for the Hellcat’s) and it equals 571.2 rwhp.
How good are the dyndynos at measuring power?
Dynos are good for measuring the CHANGE from one run to the other after modifications (tunes, etc). The baseline numbers don’t really mean a whole lot. They could tell you that you have 700 rwhp as a baseline and 750 rwhp after a tune.
