Thats a great news ,2 dynos, one in mumbai & other in banglore , At last we will get to see the actual HP figures ,not the hyped one

Great news, Karan & Domnic.

About time we started taking MHP (mental horsepower) out of the tuning equation.

Hello guys,
I am gettting an inertia dyno,with 30" rollers.This is by far the most accurate system,not because I am buying it,but because such heavy rollers can stimulate the weight of the car better.
I dont need to take the wheels off the car.So the reading a very accurate,just like the real world where the engine has the turn the wheels and tire also

It is good up to 1200 Hp,not that we have any car here over 500hp(power at wheels)Ranjit`s Supra to name one

Mine is a DynaMite!

Thank You.

Gr8 going, KS and dom.

Why didnt u get Dynojet??? Is it very expensive?

Mumbaiya · 13th November 2005, 21:56

Is it an 4 Wheel Drive or a 2 Wheel Drive System?

nitrous · 13th November 2005, 22:40

It must be a 4 wheel dyno,mumbaiya

Mumbaiya · 14th November 2005, 00:24

What are you going to charge for each Dyno Report?

Thats good news. But one question. The manufactorers measure at crank. So a 100bhp car may produce just 70hp at the wheels. So if a modded car produces 90bhp at the wheels it means an output jump by 25% but since original manufactorer claim was 100bhp, the modded car will still show lower results. How are you going to factor that in your tests

Most of the real world applications would require us to know the WHP and it is understood there are trasmission losses there are generic rules that can let you determine the true engine output. However most of the tuners around the world prefer to work with WHP figures as it would typically represent the on road figures.

Another point Karan does this system also have enviroment controls to give you true repeatable results. Also an inertia dyno you would only be doing single gear pulls, typically the second.

Karan Shah · 14th November 2005, 12:29

Hello Psycho,
Yes u can do consistant runs.The inertia dyno will only show u the max whp.1 full pull in the third gear.

Aditya0202 · 14th November 2005, 17:50

Way to go KARAN !!!!!!!!!!!

BTW how much r u gonna charge

take care
Aditya

ananthkamath · 14th November 2005, 20:33

Karan one question here..how are you going to correct for atmospheric conditions..humidity, altitude etc (SAE corrected horsepower) ?

EVO6 · 15th November 2005, 01:04

Hey Karan,
Congrats...
Inertia dyno mean simply drive you car on the test bench and make the runs ... Finally things are moving in India now...
Cheers
