4 throttle in 4g93

[leftfoot]

it isnt. its a good ol straight flow thats not so noisy, hence the big muffler.. just me trying to not wake the neighbours. and at the same time look humble and standard from behind. heh..

 

[4g93-topfuel]

we n/a still need exhaust back pressure..

 

[4g93-topfuel]

leftfoot :i think if i tell u this u will regret..u totally forgoten to spray candy blue to ur rear anti roll bar..."cusco look-a-like"..hehehe..

 

[leftfoot]

yeah but im not into looks tho..

actually back pressure is a misleading word. it should be called something else..
the 'back pressure' exists in the header. thats why NA cars have longer header configurations compared to turbo cars. it all depends on the header and that extra length of pipe after the header..

a good muffler is no muffler at all. thats why my muffler is 2 1/2 inch in and out while pipes are 2 1/4.. i like to do my own research rather than listen to what ppl say.. but again dont believe everything u read either..

 

[4g93-topfuel]

true..n/a exhaust setting is kinda stricky thro..too big the piping u will loose power...too small will have lots of gas flow restriction...in my case 2 times changing piping diameter..own sdn.bhd R&D..

Im not an expert let alone a sifu, adjustable cam pulleys are essential if u have cams, same goes to afr. good to here some support.. thanks mate

ps: keep updating us wif ur progress. really appreciate ur work here.

 

[H2Zero]

leftfoot - Its been quite a while so any updates .....?

 

[H2Zero]

no updates

 

[leftfoot]

I have updates, but without pictures I felt it wasnt enuf for you guys. heheaha. Anyway, Just installed a custom made underdrive crank pulley yesterday and boy I could feel the low revs free now.

its made of aluminium, mere 1kg in weight (underdrive) means belts are now shorter. to be exact, I use 5pk 870 for the ps pump (no ac), and 4pk 715 for the alternator.

because of the lightness of the pulley, I no longer have bogged down idle whenever I turn the manual fan switch or turn up/down my power window.. hehehe

sorry no pics. told u will let u guys down. :) I'll take some today already installed, If I remember. no promises.
