Default General questions relating to Supercharging V6's

Lets try a thread here about supercharging questions in general. Will keep it to the Holden V6 for now, if there is demand for info regarding other engines we could try starting another thread. The questions do not specifically have to be about Raptor product, this is more a general help thread for forum members

So take it away

I'll go first then... what's the maximum safe compression you can run for a rebuilt engine with a blower (of any make)?

just noticed you're in Mackay... you have a shop here?

Thumbs up

As you can see it is variable, depends on pressure you want to run, the grade of fuel you have access to, combustion chamber design, camshaft and on and on. Way too much for me to cover. What I am going to provide here is a very useful chart. Boost pressure is across the top and engine static compression is down the left side. The figures out in the middle are the static plus the boost giving total compression. Keeping <13:5 total compression is a suggestion.

Of course no sooner than I have said that and everyone can cite examples of engines and kits far above 13.5 :1 and to the opposite side of the scale as well.

Seek advice from your tuner/engine builder as to what total compression is good for your machine especially at rebuild time.


Enjoy


Yes we are in Mackay, we only have our manufacturing premises, not open to public. We distribute via the trade and web. If you are in Mackay you can purchase Raptor from the following resellers, JAM Performance, LS1 Proformance and PRE Dyno Tuning

How long will it be before you have superchargers for VY's and roughly what would the price be including shipping to NSW

G'Day
I got a standard VY 'S' 2004 and was just wondering what a S/C actually does?? From what i understand they force feed air?? Apart from the extra power what effect do they have on fuel usage, engine reliabitity, overall engine life? and as above about how much for a kit and do you have a feel for around how much a mechanic would charfe to fit, I have a feeling that it has a few 000's on the end of it.
Thanks for your time
Dan

Post VY 2004 supercharging

dan-wess


For some basic supercharger theory I will refer you to our webpage http://www.raptorsc.com.au/products.php this explains briefly how the supercharger works.

The supercharger does forcefeed air into the engine, and more power is made when more fuel is added to this air, as a result more engery (thermal) is released and in turn exerts increased force onto the pistons giving the seat of your pants a bigger thrill

Does this effect fuel usage, well that depends on your driving style, if you drive around never using any of the available boost then your fuel economy will be identical to what it is now. If you give it full throttle everywhere then your full throttle fuel consumption will be greater than it is now.

Does it effect engine reliability, in its self the SC system will stress the engine more than it currently is but not greater than what it can take. Reliability is more often determined by servicing frequency, fuel quality, tuning, oil quality and driver use/abuse. All the same factors are true in terms of engine life.

I will PM you the kit price


Fitting

Well how long is a piece of string? I will cite some examples and leave you to work the rest out. These are proven examples.

A normal DIY person and mate on a Saturday will take most of the day to fit it.

A reasonable mechanic who has never seen the kit before can get it sorted in 5 hrs.

A person familiar with the kit with an offsider will go from stock to driving away boosted in 2hrs max, (and thats on a Friday afternoon lol)

Most people have an idea what a mechanics hourly rate is so you should be able to work it out from that. Shouldn't be too many 0's on it lol

Hope thats covered it for you.

What about engineering approval?
engine management? I was talking to a friend tonight who has a raptor fitted, and he uses a piggyback ECU (custom built according to him) could the delco just be altered with kalmaker?

The forgotten

Transport department approval in Qld for Raptor is straight forward, any kit fitted by us in Qld will generally be carrying the blue mod plate and be in compliance with regulations. Cost is generally $100 if done through us.

There are some people with a Raptor supercharger fitted by resellers (JAM), these resellers sometimes choose to offer their own management solution, we think in the case you are talking about the vehicle will have a Moristech piggyback ECU fitted. One of our resellers is right into those.

If a full kit is purchased from Raptor it will contain a new MEMCAL unless you choose to have your own tuner do a custom tune. When you purchase a kit/system you can specify if you want a new memcal or whether you want the piggyback when purchasing from an agent.

You in Mackay or close by?

yeah mate I'm in mackay.
Don't know if you ever met Alan (white s1 VG manual ute with red VT Clubby kit) but anyway, he's who I've been talking to.
I'd like to fit the kit myself, but as always, some things may need alteration, or I might have insufficient tools (hey, I'm working on it).
Not sure about the brand, but he had it fitted and tuned by JAM. I have nothing against any of your resellers, but in my limited experience, you can get things cheaper by buying it yourself, but most shops don't like to skimp out on the mark-up they can get as a reseller.
not too sure about an aftermarket ECU, as I have the fabulous electronic auto (definitely considering converting to hydraulic with the new engine). oh wait.. piggyback... never mind

The Forgotten, no I haven't met Alan and have only seen that vehicle at a distance.

You are sincerely welcome to fit the kit yourself 99% of all Raptor customer do their own fitting. There is nothing to modify, so apart from basic tools you will be just fine.

You can buy a tuned MEMCAL with the system, you could add a piggyback ECU ....... whatever, there are all manner of options should you want to do that. The tune supplied by Raptor will cover the following without retune, intercooler, higher lift rockers and extractors/exhaust.

PM me me with phone number if you want to have a discussion about it, whatever we are easy.
