3.8, auto, 3.08 diff, my headers, M and H muffler, mandrel zorst, HSV chip. needs MORE for 2nd and 3rd gear passing. Any tips. apart from different diff gears, to help with open road 'getupngo'! Not too keen on opening the motor just yet. 314,xxxkm's, but no noises, no oil usage, regular oil changes and tuning (plug gaps and leads etc) And. have thought about a turbo, but they only work at 'revs', however, the V6 likes revs anyway (which makes me think lower gears would suffice) but it's our going away car and economy is still 'up there'. What about a different manifold, porting (can do it myself) etc! Just trying to keep it cheap as possible. And please. no jappa thoughts!

Stickers! Lots of stickers. at 5hp/sticker, there are big gains to be made
Ok seriously, what is the intake system like on your car! (sorry, not too clued up on the VN). If the airbox is a good design, maybe fit a high flow panel filter in there. If the airbox is restrictive fit a POD filter and make a cold air box/cold air intake for it.
That's not going to give you big power gains, but good airflow in and out are important in the quest for power

Bolt on supercharger that runs off a button so you can turn it on or off when you need it.Castlemaine rod shop used to do the kits.

if you are feeling mildly adventurous, I would say to look at ditching the slushbox and putting a 5spd in it. The auto 3.8's go nice but they do lack that certain je ne sais quoi. The 5spd ones arent the most pleasant box to shift but boy do they honk along nicely

oh and make sure your coilpacks are all tickety-boo, it is quite suirprising how much of an effect they can have if they are a bit sad
Yeah well, that was my first choice. however. it's 'her' car and she don't do manual boxes.

Had an 'issue' a while ago. bought a new coil pack, but not fitted (still in the shed), as the current one is still doing the job. as tested.

A nutter (enthusiast).
What about fitting with the Supercharged engine from a Calais!
Surely that would be relatively easy!

lets face it, without spending dollars you aint gonna get power gains, V8, turbo or super charger .

I realise horsepower costs dollars, how many dollars do I have to spend for 'just a little bit more'! If it was the old red six, I know how to make them perform, computers are beyond my reckoning. Oh, there was no intake restictor either!

I watched a vid on youtube where some Aussie guy had modded up his V6 Commie, I cant remember the exact specs but he had bolted turbos to it etc. I asked him why bother with a V6 and why not just start with a big engine! He had been down that road with LS1's and reckoned the V6 produced way more low down, 'off the mark' power for less money. It was bloody impressive anyway. pity I didnt favourite the link.
Either way, its going to cost you a bit to get anything much more significant out of it.
they also have bored out throttle bodies etc. pricing is pretty good

seriously now. if its a series2 engine, check that the throttle body to inlet valley cone spacer has been removed. Lots of people completely forget its there and forgo the 5horsepower it holds back. located between throttle body and inlet manifold
