Hi there,

Quick question........

What power can you get from a standard 2004 monaro 5.7 by adding a supercharger and what are the likely costs?

Thanks and all the best.

Martin.

Say I wanted 450-500bhp from the 5.7, how much would that cost?

Just looking for rough figures at the moment.

Thanks.

Martin.

£4-5k, but you would be wise to look at other upgrades required too.

For example the brakes on the 04 CV8 are crap. Fitting new ones are about £2,000-£2,500

The exhaust is worth looking at too, this would be £1,000 minimum but depends on whether you have the headers done as well.

It all adds up eek

It is worth speaking to one of the tuning companies on the FAQ page, they are all willing to chat through the options and lightening your wallet

£3.5k should cover a 5 psi blower from LSV, including remap on their rolling road, expect a min of 490 brake, some have achieved 580 on their 5 psi kit.

8 psi blower with intercooler & other mods would be double if not more cost wise for same power but a totally different power delivery.

LSV are £3.5k + VAT so roughly £4k

Not wanting to open the can of worms again but I would love to know how LSV can increase power to 580bhp on 5psi

To be honest, the car in question was a very good example to start with in as much as standard it produced more power than than quoted figures

strange temperature compensations skewing the corrections possibly....


And DD rollers estimate flywheel figures, rather than performing any sort of measurement ??

Thats why rwhp figures tend to be a better bet, and is what the DD rollers are built to do in the first place..

Yeh 583hp is possible with IT's of 75 degrees and power losses of 30% (according to LSV!) but anyone with any sanity must realise that these figures are not going to happen on 5 psi. I'm not saying the cars aren't bloody quick but come on people... rolleyes

Realistically just bolting a 5psi supercharger onto your standard 04 monaro will give you approx. a 100hp gain so you would be looking at 430+hp at the flywheel. Add headers, exhaust etc. etc. and you would probably be around 480hp, wack the boost up and you can go pretty much as far as you want!

Oooh, dyno figures again!

I am coming to the conclusion that dynos should be banned. They must cause as many arguments as religion or politics.

In my mind dyno figures should be used as an indication as to how your car is running following mods etc. I used to be a dyno "whore" and always wanted to see those high numbers. I have now come to the conclusion that it really doesn't matter what numbers there are on a piece of paper, it is how it drives that is the important bit

Yes I agree, dynos should ONLY be used to indicate increases from mods as we too have found out but when people intentionally fiddle numbers to make the results appear higher than they should be, it gives people the impression that the product being sold is better than it is (tantamount to false advertising) - I'm not saying the Linden supercharger isn't a great product, but why is it necessary to boost the numbers when they would already have being very respectable anyway? It seems completley ludicrous and is unfair to both the customer and the other tuning companies, so why do it?

Careful what you are saying there Dan!

I am not going to go down the line of saying that any tuners fiddle their numbers - I don't know enough about dynos to know how much control over the numbers the operators have. What I will say though is I always use an independent dyno.

Bringing this back to (almost) the original topic....

Is the 04 CV8 engine the same as the 04 VXR?

I know they are both LS1 but is there any difference at all apart from a different tune?

Oh well, someone had to have the balls to say it! I'll only be tried as a juvenile in court anyway rofl

And the VXR engine is mechanically exactly the same apart from a better exhaust and manifolds I think as well as the better tune.

exact question i was asking a few months back...

ended up with a hsv gts as the premium brakes are much better (hence no extra cost for big brakes) and that i got it for £13.5k - which allowed for a charger from lsv costing £3k fitted including vat 16500 for a 530bhp car - good value i think - attracts a lot of interest oposed to yobs wanting to key it! much better than any porsche IMO

take all the bhp figures with a pinch of salt - a vortech charger running 5psi will get around 500 gee gee's - the difference between 5psi and 8 psi in my opinion is marginal per £! do a search for capa and vortech in au and us

positive displacement chargers are great low down but i already have traction problems and dont fancy frying the clutch - plus are somewhat more expensive.

my tip is have a look around at both the monaro and hsv - both great cars, but very different

Perhaps per £££

But the more boost you use, the higher the requirement for intercooling of some sort. Put the 2 together and you do have a recipe for more power.

Either way, the £2.5k supercharger kits were a bargain.

At £3.5k a little less so, but still prety good value, and no doubt it will impress the owners.

Regardless of what LSx platform you choose....as much power as you want is only a few £££ away.
