It is a Whipple 2.3 litre twin screw, which will be run on a low boost of 6-7 lbs to start with and then increased to around 10 lbs later on.
Will also be going to an 8 rib belt and changing pulleys as well. The kit was supplied by a company here in QLD, called Richwood Technologies.
Mechanical work allready done is brake upgrade, Celsior 4 pots, Maltech brake lines, fully rebuilt trans and shift kit by MV Autos, trans cooler. A set of Neils big bore headers and a custom twin system by Lew.
Till the car comes out of the paint shop wont be able to do much till then

No offence but superchargers are seeming like such a waste of money, if you can do your own piping a TT v8 set up wouldn't cost much more if any and you'd have bucket loads more power and the loss of the air con at most.

Turbos and SC's are very different.
If you are a dyno queen and chasing a big power figure it's hard to go past a turbo.
But a SC car will less "power" could eat a turbo down the 1/4.
In my opinion in the soarer it all comes down to space really. Fitting them is a pain from what I have seen. I don't like the idea of having stinking hot turbos cuddled up to my radiator..

Have a look for your selves and see what it better; turboing a V8 isn't an easy thing to do and still keep all the luxuries that the car has standard. It can be done but not over night. Super charging (to a certain boost level can be done quickly) the Eaton M90 is a perfect charger for the low boost get off the mark like a bullet sort of thing for the V8's and relatively cheap in comparison to turboing. the twin screw like Pauls is the best in the market (so far) for good high boost,low heat,and efficency. With out intercooling out side the manifold. The best bet is to ask some one that has done and eaton charger and then wait till paul has this one fitted and see what the results are. Pauls has stated that he will be running low boost for some time But when money becomes available he will increase it boost in steps My opion is that turbos on V8's is for being a dyno king or drag strip winner.(nothing wrong with that at all) But street driving is going to be a hand full and as laggy as what the car is in standard form. the super charger will get you off the mark heaps quicker and allow you to have great top end power as well(depending on the style of charger you get) Not as much as the turboed ones but still heaps of fun so for me twin screw will be the go. http://www.whipplesuperchargers.com/

There was a whipple superchraged V8 GTO at Autosalon Perth here on the weekend that ran a 1017RWHP on the dyno comp - so they can certainly get some decent power

I guess one issue with supercharging is brand new sc's cost so much and seem to have enough trouble getting 190-220kw out of a v8. Turboing would be a bitch and a half and lotsa piping but surely there would be some turbos that would pair up nicely to a 4L v8 to give it a nice power curve. I guess one question is, is there any 'cost effective' SC solution, maybe a second hand supercharger etc? Blowing 6-8k + support mods such as exhaust etc seems like a huge amount of money for such little gains, how is boost controlled with a sc? Can you have a valve of some sort to run low boost when you want? That way you could use a decent psi charger and get good top end power but also be able to be a bit more economical for around town.

Hmm I don't agrea with you at all, a big HP turbo car can be re-tuned to whoop the arse of a less powerful supercharged vehicle down the 1/4 mile in fact if you have an autronic computer like mine you could have two completely different maps which can be applied via a laptop in a matter of seconds. One for show pony on the dyno and one for laying some rubber and low et's on the strip. All round driveability go the supercharger, very easy install and cheap to maintain. On the other hand with turbo set-ups you have more potential, two small turbo's will see your car become a weapon on the street, two medium turbo's and your car is turning heads at the track but can't build up boost on the street only the freeway, two large turbo's and your car is tyre spinning it's way to a 9 second pass and pumping out close to 1000hp so you're being blown off by starlet GT's at the lights. I reckon that whipple unit though is the money for that sort of price range, no turbo set-up for that price will be as reliable which for me is the most important thing.

david you are in the best spot out of all of us mate Neil is the man to see if Super chargers are the way you want to go as he sells and fits them. really when you look at all the power Like the big Hp cars It is all Kw's (or Hp) that sells the cars It's Torque that wins races and the torque you get out of the V8 is More than that of a TT soarer So there for the V8 is a great starting point.and also to have 220 rwkw is pretty dame good from a V8 seeing that start with around 120-130. the 2.5tt's to get them to around 250kw it will take you 8k to do it reliably so spending 8k on the V8 and getting 200kw is fantastic but its the torque that will give you the thrill.

The old SC versus turbo debate..
What I was getting at was is what Lew said. You have a 200rwkw TT, and a less than 200rwkw SC V8, and it'll give it a run for it's money because of the higher torque.
For me it comes down to ease of install and reliability.

Maybe an RB26/30 with a decent turbo is in the works haha, shat loads of torque and power. Suppose atm anything puts insurance up to much (under 25 and will be for ages) so modding isn't on my imediate horizon besides maybe an exhaust. Might not put a nissan engine in a toyota for fear of being killed by toyota fanboys
And yeah i've met neil heh, his prices are to high for my bank account though. No offence he has to make money and he does good work and the price of all the parts etc is pretty high but if I ever did go SC it would have to be a second hand one, dunno if there is a huge availability for second hand SC's that would suit the 1UZ though.

David i am so glad you laughed after saying that rot the 2jz will crap all over a rb26-30 i actually have a 32 skyline in my workshop and the owner has finally seen the light and now i am placing a 2jz in it for him. there are dyno and strip kings up here that have got 800 Hp out of a stock internal 2jz BUT 850 streached the friendship with the stock rods Sorry the head bolts had been replaced with ARP studs and nuts nothing else

Some interesting replies there, turbos were never on my shopping list, no matter how good the results can be, the overall expense to TT the V8 properly is just to much for me. It has been done in the US, and done well too.
I looked at Eatons and other brands of charger and settled on the Whipple, the extra expense was worth the benefits this style of charger can deliver.
As Lew said this will eventually be upgraded to a higher boost, this charger on a built motor is capable of being run at up to 30 lbs of boost.
I will never try for that, my goal is about 12 lbs on stock internals.
We will take pics as we go.
Got to to get car home first maybe another 2 or 3 weeks then down to Lews, dont hurry to fit it and still less than 2 days work, could easily be done in a day too. Not gunna rush it.
This is a complete kit supplied by Richwood Technologies up here in QLD.
Neil can supply and has the bonus of being able to fit as well, just about any sort of charger can be fitted to these manifolds just have to machine the top plate to suit.

i had 200 rwkw or less against a supercharged v8 at the drags. result the v8 had no chance mate.

lol i love people that compare without considering the driver, i've seen new HSV's loose to relatively stock 180sx's just due to the driver.
Yeah I checked out whipple, they seem to have some good products, very interested in the vacuum plumb back thingy so the charger uses less power when just cruising at a constant speed giving half decent economy.
Ok what kinda SC can you get for $1000 cause thats all I have to spend on my car for now haha.

It's cheaper to order the blower and rear bearings from the US and have it rebuilt here.
I got a spare unit for AU$300 including postage. The bearings on ebay work out to AU$30 for a pair by the time you pay postage. CBC in Brisbane wanted $90 each.

is that going to fit under the bonnet paul? do the twin screws run cooler fuel temps than the M90 and what boost can you run it up to without having to intercool?
Saturday, July 28, 2007 - 08:08 am, by: Lew Radbourn(Marlew)
Murray we don't know yet until it is fitted But it will be fun finding out (boost wise) yer it will fit under the bonnet if it doesn't i will be taking to Pauls new paint job with a hammer. hahahahhahahahahahhaha
