More power from buick V6
James Collins
financial state) what can I do to my VN 3.8L V6 to get more power out of it?
Even if it is just 0.1Kw. Please state the obvious incase I have not thought
of it myself.
Thanks heaps.

Copy/paste from Deja
This was one of Arnies answer to one of my question (Dated 2001-09-09)
Mods (all done inhouse)*
- cold air from VS S/C V6 (~$50 from Holden spares)
- 65mm V8 throttle body. 19% greater area than 60mm V6 T/B. Throttle
shaft
is 7mm in both. (about $100 from wrecker).
- removed the plastic bellmouth from the inlet manifold ($0). This will
DOUBLE the opening into the inlet manifold!
- VT 3.5bar fuel regulator instead of stock 3.0bar reg. This will give
around 17% more fuel pressure which is important at WOT with stock chip
coz
the ECU runs non-adaptive injector map at WOT ($?? I got mine for free
:)
- stainless steel headers & Y pipe to cat (Around $400-600 new)
- chopped the rear muffler off and replaced it with a straight pipe ($0
if
you find a 2.25" pipe lying around like me) This mod gave me a loud
"virtual" turbo whistle when I floor it ;-)
- engine oil: BP Visco 5000 ($35 for 4L)
- Full size truck trans oil cooler (got it for $99!)
* prices may vary at the time of this post.
But Arnies VP wagon pumps out about 120+ rear wheel kw.

Well, the usual approach is to free up the exhaust
(ie. extractors, then bigger exhaust), free up the
intake (look at a cold-air induction system; maybe
simply a better-flowing intakle to the airbox, or
even a used VT airbox), and then you start looking
at things like cams which start to cost a bit more
(especially as you often need a reburned chip to
make the most of cams).
Note that if your car hasn't had anything done to
the suspension for years, new suspension bushes
&/or tie-rod ends can make a big difference to the
feel of the car; makes it feel newer & more
responsive. Then new shocks & springs can be
added as well, maybe some anti-roll bars (the bars
& springs are cheaper than really good shocks, but
even a cheap brand of shock will be better than
OEM ones by now). IMHO, the feel of the car is
more important than outright speed, so if you can
make it feel sportier & make it safer at the same
time, it has to be a good thing! :)

OEM shocks are usually quite good..

Great information but how applicable is this to a S/C V6? In particular,
what sized throttle body is on the S/C model?

I dunno really but all I know is that the Ecotec V6 (non S/C) used a
68mm tb sizes. So I would assume the S/C 3800 uses the same 68mm
diameter T/B as the standard V6.

Am I getting the term "OEM" wrong? I thought OEM
was "Original Equipment / Manufacturer", as in the
shit that they fit from the factory. Or have I
got it totally around the wrong way?

overhead cams? Although driving a Holden, its unlikely you'd even know what
they are.

Yeah OHV is crap pure crap!.
I look at my SS and has OHV crap and it pumps out a crappy 227 rwkw with
some computer tweaks and exhaust changes. All I need is a ZO6 LS6
specced cam and I would have more kw's to play with. :-p

LMAO... cause thats funny.... (except i know of the case the other way)
He always is at me about ford etc (cause im a holden man and he is a ford
man) and he had nfi about what a head of a engine was.. .and the other day
he had to ask what the difference was between pushrods/overhead cam.
Next time he saids something to piss me off or is something about cars (that
he could have no idea about) im going to question him. (and also pay him out
of things he quotes and knows nothing about)

Yeah I have a friend that is a real Ford nut. Its either Fords or
Bollocks he talks about sometimes Ford and Bollocks at the same time.
But a seriously funny guy when he talks crap! :-p

particularly in the form of a disposible engine with such a bad reputation.
Take it back to 1973 and put it alongside a Leyland P76 V8 and then tell us
how good it is. The only decent holden engine was the nissan inline 6 in the
VL. Compared to the V8's ford has on offer it is neanderthal to say the
least.

No, you got it right.. but generally the OEM shocks on cars are quite good,
I was talking to a friend who works for a suspension company, and he was
saying that he would put OEM (toyota in this case) below brands like koni,
but better than brands like monroe, he also rated KYB shocks between OEM and
konis (or similar).
maybe some of the other car manufacturers aren't as good??

Funnily enough, the most unreliable engine ever in a Commodore :P

Yeah I am like Marco don't like VL's much at all. When they come of age
they start to be wallet mongers. I would only touch a VL if it has a
mildly worked 350 SB in it. But I don't give a shit about pushrods my VP
has cost me bugger all to service and run. I have seen repair bills of
RB30 powered VL's put me off them. RB30's are better off in Skylines
imho.

This is generally true.
The problem was largely Holden's inept installation of the thing into the
Commodore chassis that made it a failure, but the fact remains that the VL
was one of Holden's *most* unreliable cars ever.

Although they didn't go through harmonics balancers though. but its
always pays off to have a few spares. Although im thinking of replacing
my harmonics balancer with a brand new one tonight. The current one is
fine but I rather be safe than sorry. Sure the 3800 isn't as smooth and
does not have OHC but has the same amount of cylinders and valves and
more torque than the a stock RB30. But its a piece of piss to service on
and its rather frugal for what it is. So Holden can stick their VL up
their arse! :-)

news:auerc4$6k3ue$1...@ID-132740.news.dfncis.de...
My uncle has had an R31 Skyline since new and over the years it has suffered
similar woes to VL RB30. Now and then he rings and tells me his Skyline is
farked again. And I keep stirring him and tell him it's that crap "VL
engine" again :) Half the time it's either the crank angle sensor or the air
flow meter, just like most VLs. I guess you don't hear about Skyline
problems as much as there are far fewer Skylines compared with VLs. Skyline
owners seem to spend *some* money on maintaining their cars compared with
many older Commodore owners who simply drive them till it dies. The RB30 is
not good at being neglected.
He has never cracked the head though and I'm not sure whether it's because
of the radiator height issue with VL's or the fact that Skyline RB30 heads
are made better (they are heat treated differently to VL heads and are not
as prone to cracking). Then again, the next time he calls it might be about
cracked heads :P

I decided a long time ago that my commo V6 doesn't need any preventative
maintenace :)
I'll just wait till shit breaks then I'll replace it. My harmonic balancer
busted when I was on a high speed cruise with a mob and I shifted back to
2nd at approx 110kph to overtake and get the tacho needle where it belongs.
Hit the nasty rev limiter a second later followed by a coupla thumps under
the car sounding like I ran over a suicidal animal. Turns out that chunks of
the harmonic balancer bonding had come off and bounced under the car. Kept
driving to the next cruise meet point and parked it at the Hungry Jacks car
park. I thought I fuked the bottom end, had a quick peek under the bonnet
and didn't notice the busted balancer in the dark so I just left the car
there and went shotgun in another car for the rest of the cruise. Went back
next day, saw the busted balancer and the outer pulley section rotated
freely about 20 degrees or so but locked at both extremes. The crank angle
sensor blades in the inner section was fine and not loose so I figure I
didn't need a tow and drove it home from Cranbourne to Doncaster! :)
Made a lot of noise but got home no worries trying to keep under 2000rpm the
whole way. Gave it one blast to 5000rpm about 500m from home to see if it'll
break right off but it didn't. Swapped in another balancer and it's been
fine for more than 50,000km now.

I've seen them do it (two of them actually), but in both of those cases it
was as a result of other cooling system faults that led the car to overheat.
The engines will basically suffer the same damage if subjected to high
temperature, like virtually any alloy head engine. The main difference is
that the Commodore is more prone to having an overheating problem as a
result of incorrect maintenance, and the Skyline isn't.

Noddy.
