Turbo upgrade or differential

**sotel** · July 16th, 2015 01:51 PM

Mga sir yung h100 (d4bx engine) po namin makupad sa ahunan anu po MA's OK na upgrade sa dalawa? Nagtanong po ako sa blumentrit may avail na turbo sa van ko pang d4bx daw palit lang daw ng manifold malaki po kaya ang ilalakas ng makina mga sir?
Sa differential po ang stock gear ratio ng van ko ay 11/43 at ang mga avail po ay 10/43
9/43
8/43 anu po kaya swak na gear ratio
Anu po kaya MA's OK o safe sa dalawa?

Kaya ko poGusto palakasin sa arangkada para po safe pag umvertake lalo pag dadaan po kami sa Santa fe or papuntang baguio

ang ratio ng 11/43 ay 3.91:1 (ibig sabihin nito 11 and "teeth" ng pinion gear at 43 naman ang "teeth" ng ring gear sa differential third member . This figure will tell you that the pinion gear has to rotate 3.91 times to complete the entire circular length of the ring gear), ang 10/43 has a ratio of 4.3:1; 9/43 is 4.78:1; and 8/43 is 5.375:1.

Kung ahunan lang po problema mo, ok na po ang regear "cause it is much simpler than installing a turbo. medyo high speed po yung stock Ring & Pinion ratio nyo na 3.91:1 (11/43). Kung available po yung 10/43 na gearing ok na po yun sa application nyo. D ko na po i-aadvice ung 8/43 kasi hindi na rin po sya gaano makatakbo ng mabilis sa open highway at di rin naman po kau siguro mgpapalit ng malalaki na gulong...

Yung 9/43 naman, ok rin sya pag parati puno ang van ninyo and or parati sa akyatan. ang drawback lang po nya is medyo kukulangin nyo yung bilis nya kahit nasa 5th gear (quinta) kayo sa open highway...

Turbo upgrade will give you 25-30% increase in hp even more if you can bump up fuel delivery and specs the turbo right meaning you can spool it at lower RPM at the same will produce sufficient Air across the power band
Turbo will give you wider gain hp and torque so you will have enough power for low end and top end unlike changing diff ratio you increase top speed you will loose acceleration or vice versa the harder you load a turbo charge engine the harder it will pull until it reach it limits
Also increase increases Klm/l
BTW the turbo charger is actually develop for high altitude application on a locomotive the higher the altitude the thiner the air turbo charger overcome that by forcing more air in the intake. I recommend using CAC or water/methanol injection to cool the charge air and maximize the gain from turbo

Paano po kung 6psi lang boost nung turbo may effect po ba yon?

Basta po tumakbo ng 120kph OK na he he dipo kaya maingay diff pag 9/43 na?

7-9 psi is good enough for N/A engines without any modification on on fuel system
6psi yes air filter nga lang may epecto na diba

better go with regearing. kasi kung turbocharger route ka e kelangan mo magpalit ng pistons at valves. hindi tatagal ang N/A piston kung sasalpakan mo ng turbo. tsaka injection pump kelangan mo din magpalit.

sa 4.3 gear diff compromise na between speed and heavy loading (torque).

nung pinalitan ko kasi ng transmission (galing sa hyundai) yung L3 ng pinsan ko e bumilis pero humina umakyat. kaya isusunod namin yung differential na palitan. finorego na namin yung change engine (N/A to turbo).
