the key point is to fine tune ur engine AFR and fuel mapping perfectly across the rpm range... experience tuner can do so on carburetor engine.... only the technique and art of doing so divides both world...

thats why it is important to only have 1 tuner for ur engine if u are running on carburetor engine... only he knows what jet/choke size running in carburetor to match ur engine specifications...

as for fuel injection, everything is displayed in graph/data form... there is no black art involves if u do ur learning right... most tuners nowadays can tune most/variety of cars while to find a good carburetor tuner is not that easy....

Yeah, there's a heatshield there...but was wondering whether it'll be better to extend the air filter to the front of the battery...

generally , d longer d pipe, d more it is optimise for lower rpm...but higher rev can compensate usin larger size pipe,,...

true... longer intake pipe improves low end torque...

hi , if i change air filter to redline or simota , will it improved fc ? more drive in city ... car is kenari . Should i add grouding point or change air filter ? coz my car adi 5 years ... which one is better changing first ?
*
air filter change to drop-in ones can adi... dont go for open pod if u alwiz drive around town at low speed...
add grounding points gives minimal performance improvement...
i recommend u to get lightened crankpulley...

aiyo... then i should just forget about it...

anyhow,

stock car 1.6 = on the over-run, got little brrrp brrrp sound
1.3 with Sflow = also got little brrrp brrp on over run

i wonder stock car 1.6 -> sflow 1.6 will have over-run sound?

I just change the muffler only... Will the horsepower increase?? Put how many inch of muffler is the best?
*
automatic or manual transmission??... manual go for straight flow muffler inlet 1.8-2.0inch.... automatic go for s-flow muffler inlet 1.8-2.0inch....

as far as i know, japan muffler mostly come in minimum 2.3inch... get an s-flow unit will be good...

Brother... I am driving manual transmission... As your means, I change my muffler into straight flow izzit? Will the outlet effect the horsepower too?  blink.gif
*
outlet/tip of the muffler doesnt affect the performance... the inlet and inner diameter of the muffler that matters...

QUOTE(vr2turbo @ Dec 3 2011, 08:52 PM)
If changing only rear muffler to straight through, should not affect low and mid, but high will improve.
exhaust sifus, correct me if wrong..... blush.gif

slightly smaller diameter will induce sufficient back pressure to improve low-mid torque... bigger and less restrictive muffler will free up backpressure, allowing slightly better higher rpm gain...

change to fuel injection u must have the complete kit la... u will need an external fuel pump... convert to fuel injection dont need 3k laa... around 2k and below can settle... coz workmanship charges varies alot... injection kit nowadays cost approx 1k...

benefits??... not much i guess... dont expect fuel injection to be super fuel saving compare to carburetor... mayb slightly better only...

Hmm... will the power better?
*
depends on how "out of tune" is ur current carburetor setting... in most case, it only gives smoother drive compare to carburetor.... if ur carburetor is well maintained and tuned, i see no reason why fuel injection will be more superior...

the only reason for people to convert fuel injection is that if the carburetor no longer able to support the change in engine setup... for example, increased in displacement, using aggressive cam profiles, forced induction...

increased in displacement... for aisan carburetor, fuel jets are not interchangable... they only have such limited tuning frame to work with... on higher revs, it might not be able to supply enough fuel to the engine...

aggressive cam profile... on fuel injection, fuel trimming with absolute control on ignition timing is vital in producing proper fine tuning for an engine to run aggressive cams.... i'm talking about cam degree way above 292deg.... without fuel injection management, ur engine might not even able to maintain revs in idling...

forced induction... for obvious reason, air delivery into engine is not linear compare to naturally aspirated engine... sudden surge of boost needs sudden additional supply of fuel into the engine... u cannot do that with carburetor... well, at least not with high boost pressure...
