ok..
lets go through each chart one by one ..and lets assume the Dyno is not manipulated for this..
1] (a)the 1st dyno chart is with a D16 engine which makes 130 BHP in its stock form with no mods none of our Indian Honda's are D16 and make 130 BHP in stock form.
(b) secondly the D16 on the Dyno is not stock, it is running bismoto cam and valvetrain,11:1 CR and RS head
(c) the fuel quality is much better in US and the ECU's are tuned for more power as compared to Indian ECUs
considering point (a) (b) and (c) if they make 6 WHP , it is feasible.
but is it feasible on a stock Indian Honda engine I dont think 10 WHP is possible..
2]
(a)The second dyno chart shows a D16 and to reiterate its more powerful in stock form than our Indian stock Honda
(b)To add to this, the D16 in consideration is not even stock it is a "Bisimoto hi compression prototype"
this "prototype hi compression D16" can make 10 WHP with those headers , but will a stock Indian Honda with normal compression also make 10 WHP is doubtful
3]
(a) The 3rd dyno chart is showing a D16Z6 which again in stock form already makes more power than our Indian Honda in stock form
(b) Its a 1600 cc engine tuned with ECU for octane in US
Its basically a bigger engine running better fuel and making more BHP so it will make more gains with a header as compared to the Indian 1500 cc engine with a ECU detuned for low octane/bad fuel making only 106 BHP ..
consider (a) and (b), do u think we can get 10 BHP with same race header bolted to our Indian Honda.. ?
I think all 3 dyno charts in the link are covererd.
guys what u think ? can we directly relate to those dyno readouts to ur stock Honda engines ? also dyno charts of same engine with JDM or USDM ECU cannot be same for our Indian ECU..
