Hai alvin24....

We dyno at the same shop...together about 15 cars...this is my 1st expirience in dyno

91 oversize piston - 96 hp
91 standard - 88 hp
92 standard - 91 hp
mivec md 1.6 - 119 hp
GTI 1.8 - 116 hp
mivec 1.8 - 160 hp
GTI evo 3 - 210 hp

me got 78.2 hp.....haha...
oversize piston also
but i not meticulous while taking care of the engine....like i said, not service the engine, using cheap oil, plug not changing, got bent at my rim...

Dyno is on wheel...not on engine

But i not frustated on the result....just wondering....why my hp is low than others....still happy becoz test on the road the result differ than the hp...lol

2yrs ago dyno tune my emanage for 4g91 wif 92SOHC block @ JC Racing = 107hp on wheel...
wif some other simple mods like pnp, 1.8cams, fuel reg, racing clutch, lighten flywheel, exhaust.....
one sifu dat really squeeze the hell out of 4g91 is bro JoeMirage....can ask him wat hantu he put inside....

hahaha.. aiya calvin! me no monster :slug:

btw i haven't got the chance to dyno my 91 but all i can say that it is on par with std mivec 1.6. now im using 93 already because my 91 kebabom. but if u hunger for more power but want to stay with 91 block, then go for highcam (duration depends on the engine compression and what suit for u) and fine tune with piggyback at least. the highest 91 that i came across with just oversize piston and emanage is 115whp at gt auto. might be other 91 users with crazy hp...

91 oversize pistons,meaning 81mm?? same as 92/93 pistons??

 

[xtremeboost]

wahhh very high compression! I use standard 92 high comp piston, lower compression the mivec piston.

 

[xtremeboost]

okla ayell....but i think want to try use honda or something high comp 83mm....next project...hehe...its anybody want to sell 1.8 cylinder head?rojer me plz...:call2:...if my next project done i will dyno my car...hahahaha....hope more then 100..

 

[azrin95]

azrin....i never dyno my car .....hahaha....i dont know how much my hp.....where do u live...?

At Old Klang Road....

Dyno done at Millenium Sunway.....dyno at 4th gear

My spec:-

81 mm mivec piston
1.8 tb & wiring, AFS 339
240 injector - i think this cause my fuel so rich - above 12
Adj cam - set hi-end
4 wheel gb lock to 2 wheel - is this can cause low hp?...
8.5" flywheel with standard clutch plate - previously using 9" gsr f/w


Quite sometime the 'check engine' will appear when rpm below 3k..... - this i think got something wrong on the adj cam setting

 

[ACQ2305]

not looking down on u bro,but after all those mods,78hp is kinda low ,dont u think?? not tune properly??

Maybe..i don't mind about it...but the result differ while on the road....

Just suka-suka only.....first time expirience in dyno....what factor can decrease or increase the hp?

More money, more h/p can get.....hehehehh

 

[xtremeboost]

all bro or expert....any info about r3 cam stage one?same as putra cam or not?

 

[alvin24]

azrin95,

I reckon your issue here is that you don't have a management. Get one then your numbers should be doing pretty well coz' now ur ride will be really out of tune =p Especially with the oversized pistons and non-standard injector size.
I suggest yo go with emanage. =p
