Highest hp on 4g93 sohc Na

[^pomen_GTR^]

hello Ryuuken,

appreciate you reply.

sadly, I only got 123.60 wheel horse power after dyno

still wondering where the problem is at..any idea is welcome

that was about spot-on from ryuuken's calculation...

mainly because u still didnt install any performance camshaft.....but i think your torque value got massive increase from stock baseline....

HP on wheel is always about 20-30% less than the power on engine due to drivetrain losses. So let's say we take 25% loss then your 123.6whp comes to about 164hp on engine.

6UE5t,

thanks for sharing.

proton claims about 140-ish horse power for 1.8 dohc's .

is that figure based on wheel or crank horsepower..

All manufacturers spec are @ crank.

hi 6UE5t,

thank you.

do you know how much horse power does the 1.8 putra manual 1997 model have on it's crank when it rolled out of the factory in stock condition

Supposedly as Ryuuken mentioned before, about 138hp.

do you know if code E camshafts are better than code D..please share

Having 164 HP is actually pretty nice for a 1.8 DOHC.
Is the car daily driven? If daily driven then HP is not really everything.
There's no car on the road with 600HP will use the total 600HP fully on the road.. we got traffics to consider tau.ahahahhahahah...
For me, last time when i used to play proton, i install it almost mildly until i crush the car in to a gutter and it became a drag car.
If i were you, with that kind of current settings i have, my next step would probably a mild 254 or 264 camshaft. i wouldn't go up to 272 or higher because of the lumpy idling which would cause much of a stress..not towards the engine, but to me,the driver.
Plus on a side note, higher cam degree would put more power on the top end, but not the low and mid.
As one said just now,i also personally think that your torque value have increased well.
After i've installed a cam from either matspeed or powerzone, i would go on to proceed with my exhaust header/extracxtor, that one would work wonders with the current exhaust setting you have.
Lastly,i would do a complete intake manifold with Oversize TB. Open pod is not really recommended,just my 2 cents. Because a bare open pod would just suck hot air from the engine heat. If wanna go open pod,then it's best to have a cold airbox.

This one i have no theory to support the engineering dynamic nor i have the evidence to say so myself.
But last time i always heard about this, and they say the Code E is the better ones.
Myth,Hype or Facts? Not sure.

 

[^pomen_GTR^]

nobody will knew whats the differences between code D,E or whatever code differences in the camshaft...unless he personally dialled the cam and check the spec during dialling.....


but...i knew there is some differences in cam spec from factory mainly for europe/japan spec to suits the consumer (fuel etc etc)...

Isn't code D meant for 4G93T where the turbo equipped engine has a lower lift & duration?
