Vn question, bellmouth, cop chip...more power
Hi guys
I just joined this forum and have a few question
I just bought a VN from my mate's uncle
it's 3.8 buick engine, 1989 model
White colour and in very good condition...only 220 000 km's
It's totally stock and untouched
I did some research how to make more power and I read a few things about the 'bellmouth'
what does this do ? should i remove it ?
thanks all

oh...and it's an 's' model it that makes any difference
you can remove it if you like
do a search
Don't think the 89's had a belmouth
yeah they did...
late 90 and 91 models did not as far as i know
Series 1 motors didnt have the bellmouth. series 2 motors did.
from 90 model onwards DO have it and I'm pretty sure 89s didnt, Holden put the belouth in after the series ones to smooth out idle by distributing the air more evenly across the cylinders, as a result some throttle response was lost, so by removing it you will not gain kws just response, but idle quality will suffer a little if you remove it, you can better the idle with a cold air intake. Hope this helps
i got confused
it's the other way round
early v6's did not have them
easies way to tell his thermostat/top hose location
if it's located on the front of the engine it's series II and therefore no bell bellmouth

Thanks all.
It looks like i need to find other ways to improve power
Are cop car chips any good for power ?
Some people say it's rubbish, but my mate picked up at least 10kw in his VP with cop chip

Sorry ? What's wrong with my question ?
Isn't this what forums are for, to talk about things that some disagree on ?

Do a search. Cop chip is bs.

Well that's what some people say, but my mate swears that the car had more power after he installed it

Oh...just realised this is for VS
It probably would not work on VN

There is no such thing as a cop chip, if there was everyone would be using them in there cars for more power...
You would be wasting your money buying one its just the same as a standard memcal chip

Bellmouth was installed in the 90+ engines, 88 & 89 engines do not have it..
As above, no such thing as a "cop chip". Cops, taxi's, ambos and anything else commercial that has radio gear in the car used a better shielded ecu and wiring loom to avoid rf interference, the memcals make little difference, only noticeable difference would be if you replaced a really early version of the tune with a newer memcal where they'd had time to iron out some bugs....

It looks like I should not get it.
What are some good mods for VN V6 ?
I have approx. $300 to spend right now
Maybe a cold air intake or MSD coils

Thanks
I will look them up
Are they reputable ?
coils are a waste on a stock motor imho.
cai will only make a noticeable difference once you're doing 80+km/h

The V6 cop cars did not have a different chip to make them faster, that whole cop chip thing is a myth. They have the same chip as the commodores that were sold at dealers.
The only cop chip you'll find around come in little packets and are covered in salt and vinegar flavouring.

I found an old chip behind the back seat in the VR and that was ex cop?
