G'day guys,

I am thinking about adding a bit more grunt to my VE Commodore....and have been thinking about either putting in a turbo or supercharger.

At the moment, all I have is an SS inductions cold air intake - so it's pretty much stock standard at the moment.

Prior to any upgrade of either a turbo or SC, I would do a full exhaust upgrade including headers.

So, once that is done, bring on the extra grunt!

I drive my car every day to and from work but also do a lot of highway driving. I want the car to still be driveable, but to have those extra horsies ready if I want/need them.

I don't want to do too many modifactions - i.e. I want to be able to remove any turbo or SC when I sell the car (if I have to) and then sell the turbo or SC second hand. I don't want to have to cut into any metal either.

I have had a look on the CAPA website at their SC kits for the VE. I was thinking of just the entry level kit at $5995, or possibly the next one for $6995.

I'm not too concerned about fuel economy...Afterall, I didn't buy a V8 to begin with cos I am worried about fuel economy or the environment (yeah I know, I'm going to hell...I was going there anyway so it doesn't matter).

Any advice/suggestions/recommendations/things to avoid or be wary of/places in Melbourne to talk to would be greatly appreciated.

Thanks,

Andrew

I would go with the supercharger, don't get me wrong I still love the good old snail but they seem to suit little riced up straight fours, where as a nice big SC will give you the extra mans grunt you're looking for in a V8.
Just my 2c.

Check this turbo 6 litre Commodore street car out.

Yeah...looks pretty nice...but I'm not really wanting to do anything that crazy...

2 words, holy sh*t!
Well if we are going there we could include the FPV Typhoon with it's twin turbo pulling near 20psi or something ridiculous. But that car is going to need a full engine rebuild in about 40,000km because the boost rapes it.

I stick by going with the SC.

twin screw supercharger ftw!

i would go the SC route, just cause im a torque junky. you will get lots of low down grunt and tractability. i find turbo's are a little to peaky, and lag sucks donkey balls.

I like turbos, better traction off the line as you need the turbo to spool to get power and overall more power really. SC still kick major ass though.

I've been in a turbo'ed LS1 (all installed by a non-mechanic, but tuned by a pro for 366rwkw) and there was no lag... Foot down = instantly stuck to seat. It worked out cheaper than kits available when all parts bought separate and from "contacts"

Just decided to make up a word there did you???

After hearing Jims TTVYSS's car driving past on Chapel street, I wouldn't have to think twice about turboing the V8!
V8's usually have the torque but lack the ponies, from my understanding, a turbo helps out with hp over torque and a supercharger being vice-versa. Turbos have a better power:weight, can be better on fuel and spool quite early if all set-up correctly, you best better off going to a tuner shop and ask around for options.

Tractability

Omigosh... This is what I did to check and got nothing that related to cars lol.

Turbo always going to build more better power.

Supercharger is going to be more reliable... and more tuneable with a RRFPR. Your stock engine will last longer too. However the supercharged V6's aren't very fast imo... you get much more power from turbo's.

I'd just Vortech/Powerdyne blower it, upgrade the exhaust system and run 10psi. Change injectors and rrfpr. Supercharged you could do it for like $5k. Turbo more like $10k because of engine management and intercooler/exhaust plumbing.

do both like those new pugs

Twin turbo LS1 and LS2 kits. Best value for money power out there. Was looking into it with my LS2 SS ute a little while back. This looks like the best out there. They export to the states mainly for the pontiacs over there.

Wow, that's a nicely engineered kit.

Turbos rule. More efficient, and most importantly adjustable boost.

I still can't believe they sell non-intercooled super charger kits, try running even 6psi on a 40 degree summer day without a cooler, pure madness. You can only pull so much timing out!

I always understood screw type compressors were more efficient than turbos?

Turbos use wasted energy from the exhaust gas.

Phil

turbo's are more efficiant.

but i still would go a SC over a turbo on an 8 anyday.

turbo on an 8 will still give you lag unless you get a small turbo, but then it will run outta huff anyway.
plus then you have the underbonet tempretures that they create etc.

supercharger will give you nice even power, loads of low down torque, less heat in the engine bay, they sound porn (not like a wanker sneazing) and if you have a cut through with something like a GM 6/71 pokin though, you have instant street cred!
(but i would go something like a vortex)

400rwkw

eh nothing special

there is a commo on here putting out around 1000hp at the rear wheels

i lol'd

Easy way to prevent that.

It's called a plumb-back BOV.

Phil

PS You want aural porn -OMG turbo Indy car.

Actually with an 8 you'll get away with a bigger turbo for down-low spool compared to a 4 or a 6. If you look at the dynosheet on the TT LS1, produces over 200rwkw at 3000 rounds.

Hmm, 395rwkw..... I've seen more out of a 6 single turbo. Torque is intense though, and I'm more than sure it's reliable + economical like intended. Jim's TTVYSS produces 612rwkw on an incomplete, lazy tune. but then again his car costs half a house.
