Any common problems with BPT engines?

[dc_rock]

who dare to say B8 engines got alot of problems?! Saya Membangkang~! haha

i use to build a VR4 with a partner, build till no more money... good power but reliability tak cun at all... B8 different story, power maybe abit harder to extract but reliability is superb... the engine is very strong... once you know how to pull its power, you will enjoy every moment of it..

the only problem i faced with my b8 halfcut was alternator problem and aircond pully... which repairs was very very cheap... other than that, it has served me well in smoking other people on the highways... woohoo...

IMHO VJ20s don't reliably run above 1 bar. Maybe you can get more boost from it, but the turbine shaft isn't built to spin faster than that to get above 1 bar of boost. The lifespan of the turbo will be much shorter.

There should be no issues about engine response at low boost with proper tuning. It's all in the tuning guys. Invest in a good ECU and dyno tuning.

It's not difficult to extract power from B8 engines either, as long as you do it right. Remember that when you upgrade one part, you must upgrade the rest of the system as well. Then you will get maximum results. It's not just about bolting on the biggest turbo you can buy from a junkyard.

just make sure u know wut you're doing la, don't put in anything without research and advise from more experienced people, later your 180whp engine drop to 150whp... i have seen it before... too many people just simply upgrade without studying and getting the proper measurements...

Battousai... i think i've met you before... you're vina's brother right? driving the car you named "quisksilver" right?

 

[Battousai]

wah you blew my cover. the car goes by many names... hamster... bitch.. etc

 

[dc_rock]

whoa... sorry dude... haha~! i'm actually kat's friend... i didn't know you car had such 'interesting' names... anyway, it's good to know that B8 is still a very high in demand engine... all the best in you future mods...

if fate would allow it, we'll meet la... my car is quite easy to spot around Klang Valley roads...

 

[rajie]

wanted to ask for VF8 turbo how high can i boost and what will be my hp around at full boost ???
im planning to put it in before SDB

 

[Battousai]

you can expect about [email protected] bar depending on your engine health and mods.

Bros, when i engage to 1st gear, why got the krak krak sound? Only the 1st gear, others got, but rare.

 

[rajie]

my also got ....they told me my clutch going :(
breo for vf 8 can boost tilll how high??

 

[ken12292703]

Ouch Ouch~~~

So happy, at least i have sama kakis... Kekeke~~~

I am a newbie at the force induction section, keeping it as standard as possible now is my goal, upgrade one by one to sustain max boost~~~

What is your preferable boost? How much do you want to achieve?

 

[rajie]

if my turbo can support i wan to go for standard boost 1.5 bar and if turbo and fueling can support i wan push for high boost at 1.8 bar ....
but clutch have to change la

Why does everyone have this obsession with high boost? You should aim to produce your target HP with as low boost as possible. High boost puts a huge strain on your engine internals.

Rajie: to answer your question, I think the VF8 can effectively boost around 1.3 bar? But the center section of the VJ20/VF10/VF8 are all the same, so the turbine shaft isn't really happy spinning at high speed. It is my opinion that RELIABLE boost for all these turbos are about 1.0 - 1.2 bar.

long live B8!!

Thanks for the info bro. That is what i heard also, the shaft ain't happy with high revolutions.

Long live B8 with manong~~~
