Power Mods

[KrazyKazza1]

G'day,

just wondering if someone can list things to tweak [without buying anything] to make the VN get a little more power?

Instructions like your trying to teach a 5year old would help because im not very mechanically minded :P

[BIG DYL]

take your Bellmouth off that is located behind the throtly body... do you know how to take the throtly body off?


but buying stuff can be cheep:
1: K&N air filter should give about 5 to 10 hp cost between $10 to $25
2: good coolent $5 to $25 will keep the engine cool witch will make better proformence


or if you want a maxum proformence car buy a vu ss ute with a 6 speed should cost around $20,000 to $30,000

[BIG DYL]

here you go

Dont take it out.It is there for a reason

[levymetal]

some of the best mods you can do are free

1. run some tubing from airbox to front bumper (home made cai - better than holdens)
2. clean tb, make sure it's opening 100% (search howtos)
3. make sure throttle cable doesn't have any slack. and tighten kickdown cable a bit more than it should be - makes the car feel more 'sporty'
4. weight reduction. remove everything from the boot (including spare tyre). remove sound system. if you run 18s, throw them out and put the stock wheels back on. remove sound deadening. remove aircon. morton style: remove power steering. remove heater box.

then spend a bit of cash:
5. 2.5" catback
6. greenfoam tune
7. service (oil, oil filter, air filter, spark plugs, leads, fuel filter)

8. enjoy

The reasn its there is to provide a smother idle, If you want more power then you need more air geting in your engine, the bell mouth is just stopping the extra horses.

It does provide a smother idle, but not no extra power its just wish full thinking.I have been there and done that.Just make a home made cold air intake with pvc pipe from your local D.I.Y shop for around $30, job done ''more air in engine makes you go faster'''

yes more air in engine does make you go faster, have you seen how much smaller the space for the air to enter the inlet manifold is with a bell mouth? I have an issue of Street commodores where they proved it to.

no you should the Bellmouth out coz it restricts air flow so if you take that out you will get better air flow

[Tim Smtih]

Drfit clown is right as far as i'm concerned. Pod filter, custom CAI, and an upgrade to the ECU chip will do the trick. The extra air flow helps, but without the upgrade to the ECU you won't get the same results. I've had my VN for over two years and i won't be told the mods i have done haven't made a difference. The difference is quite noticeable to someone that is paying attention, some of you may have to turn down the music to notice.

after you take it out all you have to do is release some tenchen off of the throtol cable witch will bring the smoth idle

street commodores proved that it 'looks' like a restriction. however they did not prove the power gained by removing it. 7 out of 10 people say that they did not notice anything by removing it, except for a worse idle. for the 3 out of 10 people who say it worked, it's more likely that it's a placebo than anything else.

but there is no harm in removing it, you can always put it back in, so if you do it and you think it makes a difference, then i guess that's all that really matters anyway

Yes i have seen it Because I have done it. I do have have issue of that street commodores,but just because they say so does'nt make it so.I will still stick to my guns,but each to there own and its not my car.

all removing it dose is lean out 2 cylinders and over fuel the mixture for the other two at the opposite end no true power gain just placebo effect

quoted for truth. my car felt so much worse without the bellmouth so i put it back in the next day

[tomo955]

dont pull out bellmouth its there for a reason it creates air flow to the 2 rear cylinders, my little trick cut the bellmouth on a 45 degree angle
