hi all... budak baru here.... hehe

Aznan - Gen2 Cps - nambu black - DBH6934. - MT - pasir mas,kelate.

add me to the list pls...

feel free to see my car 0-180kmh...
http://www.youtube.com/watch?v=k6gdVmxNOD0


tomorrow 10k service for my car.... will make new vid after service & some mod.. wanna see have diff or not...

are you sure our engine have speedcut at 180kmh??? i still not test my car to it limit... but before this i already reach 195kmh... next time i'll try to push it to the limit...

for sure JDM 180..... normally they use fuel cut or ignition cut method to limit the max speed...
hummm... for cps, if can get only 5600rpm at 5th gear ( at what speed aa ?? 195kmh?? ).... thats mean it still not touch speed cut.... it just engine not enough power to push the car laa.... it not the speed cut issue... so mod it to 170whp... for sure it can surpass 200kmh .....

humm... maybe the neo have already upgrade.... Old campro gearbox oso have 4.0 final drive.... our cps is 4.2

thats mean it can get top speed at lower rpm than cps..... at lower rpm engine still have torque to push the car..... so the our gearbox is design for pickup, if wanna have top speed need more torque at hi rpm compare to old campro coz of gearbox ratio...

i'll try my car to ensure it can rev over 5.6k rpm or not at 5th gear.... where i can find long & stright road at kelantan..... huhuhuhhu

are you sure peak torque at 6.5k???? at 6.5k rpm is peak hp loo.....

peak torque for cps is around 4.5k rpm..... & start decrease after 4.5k slowly......


& at that speed.... enviroment resistance is great to the car... so engine need to work harder to get speed..

.......................


For the emanage..... it can work properly with our ecu... but for air fuel ratio only.... igniton timing cannot... alot of campro turbo use emanage to tune their engine....

unichip q+ oso can use to tune campro.... from what i hear, it can tune ignition & afr ..... but not sure about it....

our ecu not so smart laa..... it can be cheat oso by piggyback.... hehehe

that bridge cannot do full speed laaaa.... kekeke... very bumpy & not long enough to try speed over 200kmh...
how about we do side by side .... ??? the vid be more interesting.... wekekekeke.. win blanja milo beng..... wehehe

humm... Neo just for fuel only... if fully tune sure not impressive.. we need 2 tune ign timing oso... that will effect much on our engine... not worth buying expensive items like that...

better save money for haltech interceptor or unichip.... that item can tune afr and ignition timing... than the most important is tuner....

have a look this page
http://bluedevil76.blogspot.com

he know how to tune campro with unichip.... he already successful tune campro for 153whp... sure can tapau vtec.. stock vtec only got 120-140whp...

humm... totally different??? all na engine do same mod to gain power..... but now all can custom already... no need to wait oledy.... have money go for it....

- increase cc - bigger piston(oversize campro piston), stroker
- increase compression ratio - hi compress piston (can use campro 1.3 piston), skin head, thin metal gasket
- better flow efficiency - port & polish ,valve necking,3 angle valve cut, exhaust system , intake porting ,tb , camshaft, bigger valve etc
- tune afr & ign timing to optimum - unichip is the cheapest, megasquirt(this maybe need to change to old style throttlebody)
- cool air intake
- lighten - rim, body, moving part (crankpully, flywheel) etc
- low viscosity lub oil. ( engine oil & gearbox )
- remove unwanted load from engne ( remove powersteering, aircond compressor )
- gearbox ratio - change final drive or individual gear
- tyre circumference
- sharp edge crankshaft - need to dynamic balance
- more efficient engine - do piston ceramic coating, sleeve coating, race engine bearing
- colder engine bay - thermal warp exhaust or ceramic coating
- better electrical system - grounding & voltage stabilizer ( to ensure engine running at optimum )

i think thats all mod to gain power from na engine.... maybe still have some miss..


we oso need to do sporting mod to ensure engine running in safe condition...
- more cold heat range spark plug - faster transfer heat from combustion chamber
- radiator
- ensure engine no knocking
- metal gasket ( no need to worry, campro already metal)
- low resistance spark plug cable or hi power coil - to ensure engine no miss firing coz of hi compress engine
- use hi octane fuel -less knocking & preignition
- ensure no sharp edge in combustion chamber - can coz preignition
- etc

hope this can help...

but if use neo.... you need to know that item cheat yr signal form map sensor to ecu ....the map sensor signal 1-5volt, it variable depend on intake manifold pressure..... so if you decrease fuel at neo..... ecu will read low signal from map sensor & inject less fuel.... map sensor signal not only control fuel map... it also interrelated with ignition map... so less map sensor signal.... ecu will advance the ignition timing ... so you need to know how to tune it.... it dangerous also if someone play with it... kekekekekkee...

so from what i tell you above.... you can still play with ignition timing with neo..... hehehehe.... thats the tuner secret to get advance ign timing...... but need to counter back fuel with other devices.... hehehe

need to know more pm me....

Added on March 11, 2009, 12:57 pmif coating..... the heat will not easily loss from combustion chamber.... more heat more power to push piston....
but it not improve much in term of power....

the main coating function to keep piston cold.... normally use for turbo ( more heat producer).... + oil nozzel spray at bottom of piston.... that piston can survive at extreme condition...



this ceramic coating worth if you increase compression ratio over 13:1 .... at 13:1, you cannot use 97 octane petrol... need to race fuel to ensure yr engine can survive....

have you see dyno graph from rsimpressive ?? they use 2wd DASTEK dynamometer .... maybe the software to get the data have graph linear or correction or averaging like that.... so we see it smooth... i think both of them use same dyno machine type.... unichip make by dastek oso....

see old campro torque after tune with unichip at rsimpressive..... low torque graph superb....

huummm... dunno.... that car auto.... auto gearbox long ratio..... at 2nd gear auto nearly 3rd of cps manual if compare ratio..... that's why they use 2nd maybe....

ok... for yr info... i'll give kmh @ 6500rpm @ all campro gearbox.. all use 195/55/15 tyre...







from the table above.... if that campro auto use 3rd gear(181 kmh at 6500rpm) compare campro cps manual at 3rd gear (123kmh at 6500rpm)

so ....

181 - 123 = 58kmh different.. ( that alot )
- so cannot dyno at 3rd gear for auto..... sure show very low hp.... hahahahaha

if use 2nd gear campro auto....

123-118 = 5kmh only different....
- that why they dyno at 2nd for auto........ only 5kmh different...


5kmh diff..... that mean 2nd auto & 3rd manual ratio almost the same.....


i hope you can understand..... before talk please do some calculation..... heheheehe

hummm... i have all the gearbox ratio for campro...

just calculate it ler.... formula only.... tyre circumference, compound gear ratio..... from that we can get KMH...

for sure AT gear can get hi top speed.... but engine no power... kekekeke... feel berat looo.... no power... pickup hancus...

our campro cps mt gear just cun2..... for pickup & oso have top speed....

tomorrow i will give the ratio & formula... wanna tido oledy...

aiyooo.... you cannot compare speed like that.... on table you see camtakpro more laju rignt??.... but camtakpro need more power to move at all gear compare to campro cps.... so torque at wheel much more better for cps...

so cps can get speed more faster than camtakpro.. so cps win....

if you see vtec ratio, it super close gear + super hi rev engine = vroooommmmm

if camtakpro mod to 200hp.... for sure it can get more top speed coz of gear ratio....

if cps wanna get top speed better than camtakpro.... just change final drive or bigger tyre circumference or change 5th gear ratio... that's all...

hummm... for yr info.... they select gear depend on gear ratio that match with engine revolution..... example : engine rotate at 5000rpm, tyre rotate at 4700rpm.... so they select that gear.... that mean they want to eliminate other factor, they want to measure power closely from engine.... so other parameter need to set properly, from that we can get accurate whp......

normally japan car all close ratio, so they select 4th gear.....

here have the formula

http://en.wikipedia.org/wiki/Gear_ratio


*ps. i have software to calculate gear... no need to calculate hehehe... just give me email i can give you

bro..... please see the ratio..... i hope you understand....

it not about brand or where it come from.......... it all about ratio...

you no need to think about it..... all tuner at dyno shop know what he is doing.... hehehehe

if you want to see more power... ask the tuner to dyno at 2nd gear.... no prob bro.....

or try dyno at 5th gear..... ppl will start asking when see yr dyno sheet.... why yr cps engine so weak???? 80hp only?? hehehehe

already explain above :




i said NORMALLY japan car dyno at 4th gear....but not all japan car are close ratio.. becoz there speed limit 180kmh.... so the engineer not design the gearbox for hi speed.... have you try b16a vtec, evo, mivec... humm that car 120kmh at 5th gear around 3800-4300rpm....
i'm sorry not to explain detail.... i tought you all already notice it..


no need to VS campro or vtec or mitsu..... just see ratio... tuner know which gear to select....


no need to confuse sphiroth..... if neo r3 use 4th gear & get that power.... that was superb.... if use 3rd maybe the figure may be better...


sphiroth... which ratio are different?? maybe i type error..... please show yours... can compare... and know the correct one

slip is not the prob.... 1000hp car oso can be dyno.... 2000hp car oso can be dyno.. just 300hp turbo car noting...

i now just talking here.... before this i own wira 400hp... i oso know tuning haltech & protech... want proof oso i can give... have vid oso.... below link if someone wanna see my old car

http://www.zerotohundred.com/newforums/car...evo-400bhp.html

lol... it not slip much looo..... if over 700hp... some ppl will tekan the car while dyno.... so not slip

feel free to see my old vid...
