power increase

[38VNIT]

I old my brother who is a mechanic, i was looking into v8 injectors and throttle body, and he said that for the time being go an exaust and new computer, cause an after market computer on a stock vn will do more increase than anything and also make all the smaller mods have a bigger effect later, and he also said that v8 injectors are the same size and wont make any difference

[38VNIT]

i told** my brother

The VN V6 is a strange car, especially the series one because there's very little extra power to be had no matter what you do!, the injectors are the same and throttle body wont give you any power. The best go fast per dollar you can spend on a series 1 VN V6 is suspension and brakes (and a CAI and tune) Don't worry about the tune either on a series one unless it's cheap

[38VNIT]

lol ok, i think u underestimating the power of a series 1 and its potential, but yeah, they are not that different, but my actually question is will a new computer with exaust make a large difference, or atleast a knoticable one

[Doctor Bob]

a decent cat back exhaust, a cold air setup & a tune will make it a different car to drive.
any series will gain from a tune, replacing the computer will only empty your wallet, the standard computer is more tunable than aftermarket units in your situation.

100% noticiable but I wouldn't say large a tune on the VN V6 makes the car feel much punchier all around, In a straight line you should gain a little more from the tune than the exhaust and you might get the 1/4 mile down to 15.2 or something with both. But neither are going to give you a Dr Jekyll and Mr hide type response like you get with a tune and exhaust on the 304

Yeah you need to be realistic in what you will acheive N/A.. My stage 2 cam, extractors, cai and exhaust etc. made a difference, but nothing massive... Its not something that makes you sit there and say holy ****... In fact my reccomendation would be diff gears as my 3.9's made as much of a difference as those other mods combined (speed wise) and get a tune!

lol its a 3800 vn motor, not a 304, unless 304 is something i do not understand, and if i got a 3" zorst and extractors, cai, either a new computer or a fine tune on mine, would there be a good amount of difference cause later i plan to get a rebuild, shift kit with ratchet shifter and either a good lsd, or a mini spool... so tell me with them mods upcoming what is my best choice's, oviously CAi and an exuast/extractors will be first

[stocky]

3 inch would be a waste. get 2.5 inch

There'll be a difference.. What kind of gains are you expecting? ~150kw at the fly with the exhaust, extractors, cai and tune? With these mods you'll still be running around a 15 flat quarter mile maybe slower, and stock figures show 15.6 for the VN... So you would gain ~0.6 of a second down the quarter if you wanna look it at like that..

Do you know how much a computer costs? They are around $1200-$1500 or so... and you'll get the same gains from a new tune/memcal.

Also unless you are going a full manual valve body the ratchet shifter is a waste.

[VHSLX3300]

mate if you want a memcal which is the chip in the computer send me a pm as I have a powerchip up for grabs. I put it in mine and it made a bit of difference. more throttle response and sharper gear changes plus made me get above 70 in first If I wanted to..Cheers

[38VNIT]

ok then, im do not fully understand everything atm, and i dont really care bout quater mile time, im just chasing a bit more throttle response and trying to learn all the things about all the upgrades, so yeah go easy lol just wanna know what will do what and everything for future reference, and i was told an aftermarket computer would only be bout 500-700 so thanks for heads up...

[immortality]

as mentioned by a few before, don't do anything with your computer. just get a better tune by changing the memcal. get a nice CAI setup, most here use the VS S/C CAI from holden. about $50 +/- and 1/2 hr to fit. k&n panel filter etc. have a look throught how-to section for greenfoams post on how to make the TB open 100%. maybe knife edge the butterfly and smooth out the ridge where the TB has been bored etc. pacemaker headers with 2.5" cat back exhaust should cover it. give it a full service, good oil,plugs,leads, fuel filter. run some injector clear through it also. shiftkit the auto and fit LSD with some 3.46/3.7/3.9 gears etc service the auto and fit an external cooler also. in future you could get more power by changing the cam, upping the compression, roller rockers, porting heads etc then there is the come 4.2 stroker kit (doesn't fit s1 engines) or something like the raptor supercharger maybe. all depends on $$$$ really

[38VNIT]

kool, thats mostly what i have been told, while we are topic of power increases, whats the go with your lifters, i have been old you can make ur lifter give u better performance but im unsure if thats true...

[Not_An_Abba_Fan]

There was a guy we did an exhaust for that raced a VN on a dirt track and he had injectors out of an XE Falcon EFI model. Don't know how effective they are but he swears by them. Puts more fuel in apparently so he reckons. Played with the injector timing too I think.

[38VNIT]

if i took my car to the local holden dealer that tune up and timing and stuff, what exactly would i ask for if i wanted it tuned for power and sportiness...

Mate your clearly not listening. Holden qont do a custom tune for you, simple as that.
Service the car with good quality products.
Get some extractors and a single 2.5" exhaust.
Get a V8 throttle body.
Get a VS Super6 CAI.
Get a shift kit for the trans.
Get some diff gears and LSD.
Finally get a tune done by a workshop, not holden.
There you go.

After all that cash going out on a v6 - Buy a V8 n slot that it. Probably cheaper now that all the 'SUPER computer' and go fast bits for a v6.

[PaRaDoX]

SLAP A TURBO ON IT... hehehe FOAM, i wonder how much my series 1 will be making

[38VNIT]

lol ok thanks guys thats all im after
