Disconnecting Supercharger in VTV6 without removing it

[Jordzz]

hey guys, i rekon im gna end up buying this 5SPD VT which happens to be supercharged.
dad doesnt feel confortable with me driving around with a supercharged car..so cut a long story short how can i disconnect the supercarger without totally removing it from the engine itself.
Is it as easy to just remove the belt if so will the car run smoothly ? (like a na v6)
if not how can I ?
cheers

[VTvoodoo]

im no mechanic, but id be guessing it wont run to good, wouldn't the compression ratio be differant than a NA version

[VTLS1]

i have been told you can disconnect them as can be done with a turbo on a turbo engine but at the end of the day the engine isnt really designed or made to run this way. if hes really worried about you driving a supercharged vehicle just ask why hes worried when its legal for you to own & drive the vehicle under Australian law. if the law thinks your ok with it then so should he...................unless hes seen how you drive & thinks your a lunatic. lol

[VH commodore]

is it a factory supercharger? or aftermarket. cuz supercharged v6's didnt come out in manual, so either its got an aftermarket charger, engine has been replaced with a super6 or gerbox has been changed. u should be able to just remove the supercharger belt which shouldnt run anything else. if its factory supercharged then it will have low compression which will make it slower without the supercharger (less power) than a standard v6.

actually not sure if the supercharger will restrict airflow if its not rotating......what kinda supercharger is it?

[dannyn12]

theres not point in buying a super6 if you not want a supercharger is there

[Jordzz]

danny mate you got a point but I really want this car whther its s/c or not its monaul and a really good buy not the fact that it has a supercharger. I think it might be aftermarket sc or a whole sc l67 from a vx cos its an VT exec and they didnt come out with superchargers in the vt executives anyway did they?. so its either a L67 from an vx or someones stuck an aftermarket s/c on...
would it be easier if i stuck up a pic of the engine bay for yous ?
cheers

[VTLS1]

dude,whichever it is,it looks damn clean & tidy(under the hood anyway). If the rest of the car matches this tidyness,damn em all to hell,buy the thing . just do the usual checks for service history,any reciepts for work done etc if nothing available just listen to your gut instinct

[TVR-190]

l67s arent that powerful anyway, tell your dad not to worry.

[neet_wagon]

If you disconnect the drive belt, how is the engine going to get air?
Its only what 160kw? Just tell your dad its got less power than a bog stock standard ve v6 omega.

[ScoHar]

agree'd pick up some power figures from an L67 on paper, and some power figures from newer cars, im sure he'll see your point then.

[thedeadwalk]

it will not run smoothly not with out takeing the charger off and a tune but it will run. i'd keep the charger it's not going to do any harm as long as you don't drive like a toss

[Mick1988]

Yeah it's slower than a stock VZ/VE Commodore. I would explain to him that the Holden Supercharger doesn't give much extra power without different pulleys.

Either that or I would sell the L67 engine and buy a GOOD CONDITION standard Ecotec engine. You'll probably make at least $1,000 in the process.

[Jordzz]

YEP THANKS GUYS pretty much what i was looking for done all my research after i posted this thread ( stupid me did it the wrong way around) and since i drive my gfs VZ around quite often ive got the 2 cars power figures side by side and proved dad wrong . Cheers for your help mods please close

[Mick1988]

Now just get a 10psi pulley for your supercharger to actually make it give a decent amount of power and don't tell your dad that you've done so

[stevoss]

hey i think i can see your flaps, harden the *** up.lol

on a serious note the car wouldn't run by just disconnecting the supercharger with a different belt as without the rotors moving it would choke the engine. on l67 forums they have said you can buy an adapter plate for the front which removes the snout and then you would have to open the top cover and remove the rotors as well, only then could it run and the computer even though it does run a fuel table which is comparable to throttle position it would still be effected by the air flow past the air flow meter which means more than likely it would kinda be a pig, especially with the 8.5.1 compression compared to the ecotec 9.?.1.

Even though he has already reached a decision by the look of the pic it has a 10 PSI pulley with a Yella Terra Snout

yeah you are right, that is not the standard eaton charger, or at least not the snout and pulley.

the sc6 drives fine without the belt. Obiviously you notice the difference and I would'nt drive one for long without the belt attached, because it would be really boring... but if your belt snaps or the like, you can keep going.

I've driven mine without the belt on, and it just felt like a normal six.

Also, whilst it is fine to put maximum power figures side by side, and the rules says a p plater can drive the sc6, it is not really that simple. the alloytech will have a peak power output higher up in the rev range. the danger with an in experienced driver driving a sc 6 is the amount of torque the engine has down low. all things being equal, it is no issue still but the do tend to catch you by surprise in the rain.

6psi should be no problem, but would be interested, to know the diametre of that pulley?

Also there is a reason they didnt bring our the sc6 with a manual box, so now that you have bought it( by the sounds) take it a bit easy on the transmission.

if he is on his P's the super6 is on the prohibited list so legally he cant drive it.

Law may be different in S.A

[GM GEN3]

yeah in sa it hasnt came in yet so he can drive what he likes i think

[taztassio]

take off the charger belt, will need a 15mm ring spanner on the belt tensioner.

my car ran run without charger belt, and mine is cammed with huge lift.

i think yours will by fine

[feg]

I think in Victoria it's ok as well, they have an exemption because the make the same power as an average six. My point however is where the power is delivered, in the rev range.

Interesting NSW, are not exempting yet.

here is the link for vic, in case anyone is interested. I thought they used to have a caculator to work out how much power you can have for the weight on the vicroads website as well.

Lower perfomance turbo or super charged vehicles : VicRoads

I think it is good to have the exemption all in all if not just for resale value of the older supercharged commodores.

[And_ROOS]

I thought a supercharger was banned regardless of how much power it makes. I was reading it then, it leads me to believe i could have a supercharged VT calais (still on green Ps) because its a family car, not a performance vehicle, and that the power to weight would be lower.

And i would have thought the engine wouldn't get damaged not running the supercharger if it was a s/c engine, but that it wouldnt run efficiently therefore making it a bad decision to have it off.

IN SA a 16 year old P plater like myself can legally drive a Lambo if i could lol
