Supercharged Alloytec Or Turbo

[06vzcalais]

I Was Just After an opinion i was chattin to a fellow commodore owner the other night and we got into a bit of an argument after a slab or two about supercharging or turbocharging my 6er i have been in discusion with C.A.P.A retailer about the in valley 440kw intercooled kit serious power for around 15g but i need to upgrade a few other internals with tht sort of power figures i think.. can anyone inform me of what internals i need to upgrade and whether id be beter off spending that sort of money on a turbo set up??

[plymouth_hemi_69]

spending that amount on a turbo car would get you 1 hell of a car i tell ya go turbo aye as the s/c's from what im told run out of breath if you spend some on the internals (although stock internals can handle a fair bit) then you will have a crazy 11 sec car.correct me if im wrong

doesnt the manifold make it hard for a valley mount? there was something i remember about this cant remember what is was but i'll get back to ya, i know its something that makes alloytecs hard to valley mount..

if your going for big power i upgrade rods and pistons. drop the compression back to 9:1

[impulsive]

i thought the alloytecs had forged internals already? i know they can handle a fair bit of boost and power, would this all be neccessary, cuz if he's gonna open the motor its gonna cost big..

[monaro327]

the stock internals are forged but the rods are still pretty small and the compression is 10.2 stock. i'd go forged H beams and dished pistons to drop the cr to 9:1 if you want to venture over 12psi for a daily driver.

as i said the rods may be forged but all the pictures i've seen there still not alot of steel in them. i think the fact that the only alloytec to ever venture over 12psi to 15psi disappeared very fast confirms this. they seem to handle high rpms fine though.

Crank Driven T Trim Charger reverse rotation unit Intercooled 440Kw Vz Only $8995 for the kit $495 for the piggyback a resonable front half of the zorst with Quad Outlaw cats $900 and for some reason they charging me a shitload of labour anyone know what sort of price id be looking at for stronger internals as sugested before eg forged H beams and dished pistons

stronger internals on an alloytec at present = expensive

not what i wanted to hear *Cry* i guess ill just smash some form of boost into it whether it be turbo or supercharger i had a turbo on my 4 pot screamer scoobydoo that had "Bush Rego" wasnt to happy with the whole lag thing i think the turbo in question may of been the problem rather than turbos in whole but i love the supercharger whine and they are run at reasonably low boost im guessing to get 440 kw out of a turbo i need to be pushing about 15psi am i not correct and a charger same power for 10-12psi would this make any diff at all

[impulsive]

go the raptor supercharger, they go spastic on alloytecs, just wish i was allowed to get one..

[06vzcalais]

Im Not Legally allowed to own one either but i shal do anyways as i have other means of transport with my ComeDeo (rodeo with a few commodore parts to spruce it up) as long as i drive sensible and leave the silly stuff for track days ill be fine really wanna go on a cruise ASAP but damned work restricts this

[monaro327]

the T trim will make alot more power then a raptor blower.

capa offer 2 kits for the alloytec vz one with the V2 which will give similar results to raptors kit one with the T Trim which is more of a V8 blower capa claim 400rwkws with this one.

[monaro327]

there was a bloke on street commodore that payed about $3.5 grand for forged dished slugs and rods.

[06vzcalais]

Im Real Interested in The T-Trim I Know Alot Of People Whom Are Hangin out For Me To Get This kit Fitted As It Would Be One Of The Highest Powered VZ V6 alloys Around In Ozz (street driven) they wanna see drivability and im real intyerested in how the 5 speed will handle it a/s mode should be insane with this amount of power and having the ability to take the car to red line if needed 440kw with a zorst is assured to me by a few C.A.P.A Specialists

[impulsive]

i think you will find the Auto gearbox will struggle to keep up with the power, andyman i believe has 'tuned' his gearbox and ImpulseSV6 has a raptor kit fitted and his gearbox cant keep up with the power, although its a little better with a new shift kit.

[monaro327]

Andyman has a exec which comes with the 4spd which is tunable. the 5spd isn't which will be your main issue. alothugh there are pressure boosting kits now i believe.

hmm this may seem meerly impossible without frying the box maybe the power figures i was thinking are a bit to extreme for this car did 0 to 158kph test it was only suposed to be 100 but i got a lil carried away YouTube - 11082009001

shift kit by sure shift?

Yep, these guys.

Owning both a turbo Ecotec and supercharged alloytec I can offer an unbiased opinion on both. The supercharged alloytec is much nicer to drive and is a much better daily driver, it doesn't use fuel, its hell smoother and all round nicer on the road. But there is no way, mod for mod, boost for boost, on the same engine, that it would beat a decent sized turbo setup.

drivability in everyday situations is what i want, im not after a spastic drag car, i want something i can happily drive to the shops with but still enough power to get me out of trouble when it comes to those rice burners trying to drag you off the lights, it becomes quite embaressing when blown away by a 4 pot screamer(pulsar gti-r with spastic turbo set up)

[06vzcalais]

i got hold of those transmission blokes awaiting a reply(if i get one at all). Thanks for that

Well a blower might be better for you then, they are much easier to get traction with. My VS even when it had only 200rwkw, had issues with traction so on the street it was painful trying to get it off the line, whereas a blower comes on nice and smooth so you just mash the peddle and go.
