Senior - BHPian | ![]() Let us all of us take some deep breaths (read as said by a Yoga instruction on SAB or Doordharshan TV) Quote:
![]() BAck to topic. Like the honda engine has wide range of options for boltons like drag specific headers, someone in TBhp has GReddy headers that turn to copper or something when heated up (really cool).. how come for the Baleno G16b(?) there are no such options available? sorry ![]() | |

Infractions: 0/1 (10) | ![]() Daniel Baleno too does have engine swap options. Mainly the J18 and the J20. Its another thing all together to import these engines. One can also put in the swift sport engine too IMO. But I have not come across anyone who has tried it yet. |

Senior - BHPian | ![]() hummm. Mcl. I wasnt talking about engine swaps. At the moment happy with the G16B however was talking about something like Headers. Far cheaper and better to fabricate from guys like Raj eh? |

| ![]() there are some simple formule for the power measuremnets. work done 1>power=------- time (torque*rpm) so power= ----------------- time torque*rpm also hp=------------ - 5252 brake mean effective pressure*engine capacity in ltrs*rpm so hp=------------------------------------------------------------- 1300 torque in lb ft*2.475 bmep=----------------------------- engine capacity in litres so if hp =150 ; capacity =1.5ltrs;rpm is 7500 bmep*1.5*7500 then 150=------------------- 13000 so it comes to 173.333 psi @ 7500 rpm so only if the so called tuned honda can develop 173.33 psi at whooping 7500 rpm then its therotically possible <i said therotically> now cuas check out the bmep of current 1.5 v tec at 7500 rpm -as i dont have all the data of 1.5 v tec . then displacement in cubic inch*rpm*volumetric efficiency cfm=--------------------------------- 3456*100 will give the max consumption of air then petrol gives max power at 1:12.5 ratio so ull be getting the fuel cunsumed by the engine <assuming 100% is burnt then calculate the total energy of the fuel energy . u can convert max 20% in the most efficient petrol engines!! once u know the air consumption + u know the rpm at which the the gas speed is to be calculated then mean gas speed in ft per sec*5400*valve area in square inches rpm=-------------------------------------------------------- cylinder volume in cc it will give u the gas speed through the valves for pent roof and hemi combustion chambers estimated gas speed is standard..200;sports 215;semi race/ralley235:and full on race 260 to 280 now u do the calculations nad see........... then urself evalute the extra breathing required to gulp that kingd of air . the highest brake mean effective pressure occurs at the max torque the avrage motors run @ 165psi.rally engines run @185-205 psi bracket,racing motors range @205 to 230 psi and few exceptional motors will run @240 psi NA superbikes show @195 some nudging @200 psi . --------- this is mathematically correct interpritation of power .. now please please dont try to prove me wrong p.s. i dont have a commertial intrest in prooving my point too ! ![]() so guies please find out the figures please do the mathe <let mr know the figures too !!! |

| ![]() Have been following this thread for a long time. Just went through thw whole thing again. Noticed that it has already gone seriously OT on more than one occasions. My thoughts on this one: Why Esteems?? One will usually find the Esteem doing duty as the rental saloon at the tracks here. Its a no-brainer. Cost: Cheap to acquire and maintain. Tried and tested powerplant. Easily available upgrades (chassis/engine) and easy (and relatively cheaper) to fix if something goes kaput. Why OHCs?? Well, OHCs are the choice for most enthusiastics who do not mind paying the premium for better performance. Now, the thing to note here is: a car's performance is as good as its overall tuning and setup. So there are no constants here. Everything is variable including performance from one OHC to another. Pros of the OHC: the badge. Easily available (although not always cheap) upgrades for chassis/engine including frankenstiens. A nutter of a powerplant that begs to be thrashed and always eager to embrace the rev-limiter. Cons: Probably the only one. Acquiring cost. Although depends from place to place and the demand-supply ratio. Also the fact that (compartively)not many people bought the VTEC spec, just because they thought Hmm... 100 K plus for 6 bhp and some alloys. Naah. (Not including the people who were aware of what this anocrym meant at that time but about the non-performance oriented middle-upper class families who was the target audience for the 10 Lks+ on road sedan) And if someone has noticed both these cars (Esteem and OHC) are not out and out handlers when it comes to factory stock cars as both run a very comfy (read soft) suspension setup which is not track oriented at all. Just my $0.02. Please feel free to comment on my opinion. But no "X is better than Y" ![]() Thanks. |

| ![]() i totelly agree with u . one addition to the pros of both the cars, both the care are very light though they are not really strong enough to withstand the regular thrashing even in stock form, power to weight ratio is on the feverable side.and thats the main advantage Quote:
