I've a more interesting question. If say Bangalore had another shop with a highly regarded dyno (say Dynojet) which consistently gave higher readings, other things being equal (esp. cost) where would you take your car to be dynoed?

Completely agree, lets not get into dyno comparison now. And i would take my vehicle to a dyno which will show consistent readings, with multiple runs

Not only rally, they use it to tune the dampers they sell to their customers. Am not sure about the dyno at rental mode. You can always give them a call and check.

to keep things simple since 4 gear close to 1:1 ratio. They are not taking pains to do 3rd gear with correct ratio for each car. Next time i am making sure the guy is making 3rd gear run.

Why? If the dyno rpm is within its design range, and has been calibrated accordingly.

I'm not sure if this is the only reason they're conducting the runs in 4th gear. True, in almost all cars, 4th is very close to 1:1, but you still have the final drive (on the differential) to contend with. Does this dyno have an option of the operator simply entering the 4th gear & final drive ratios ? That should eliminate all ambiguities right ?

Hi,
'Close to', and 'not close to' should not really make a difference. In older cars, in 'direct top' power was not routed through the gears, thus no losses from that account. Nowadays, gearboxes are all indirect.

Computationally, scaling should not be a problem at all.

Entering the gear ratios might be a good way of checking the cars OE tacho. Speedos overread afterall! On a roller dyno (not the Dynapack), it would be very difficult to preworkout a engine rpm to roller rpm ratio.

Went though the entire very interesting thread. Didn't find a graph of the DDIS engine. Would someone do the needful, thanks.

Here's the dyno results from the Bangkok taxi.

Peak HP = 95. Notice how much torque is available from 2500rpm.

And its exhaust system, some snaps i had taken. What i liked most was the quality, both that of the products and the installation. Truly world class stuff.

Those snaps are a treat. Brilliant workmanship. Hats off to RRP for the quality !!

Thanks for sharing the pics

- Running a turbo? Cost?
- Who owns it?
- How much did she put out on the dyno?

[ajmat]

Leela told me it is not running a turbo yet but all the plumbing etc is in place for it

After the turbo goes in what Whp should one expect ? 200 or thereabouts ?

Here is my swift diesel dyno readings. sorry for delayed post, swiftD has put on 25,700km on its odometer at the time of she undergoing the dyno test and its a stock.
if i remember correctly leela mentioned honda, toyota were consistent in there bhp out put but not so with maruti

Thanks for posting, but the graph is very different from this http://www.team-bhp.com/forum/modifi...tml#post433632
where the peak torque comes on at about 2k rpm
