adelaide has no "R" in it dude....

oops my bad i did that in my profile as well.:wtf:

What a great read this thread has been.

By way of introduction, my name is Rob Hayden and I started the Australian Lexus Soarer Club back in 1997. I was also instrumental in assisting Bill and Steve in the UK to kick off the TIFF.

I run a Soarer UZZ32 with a genuine Japanese C's supercharger kit.

C's use a Magnuson M90 and a cast manifold of their own design. They also remanufacture the front water bridge to run the top radiator pipe out over the distributor cover on the 1UZFE and then bend it towards the radiator.

From my understanding of things, they made the frist kits to suit the LS400 (Celsior UCF10/11) and the Crown Majestic which both ran the 1UZFE back in the early 90's.

The kits sold well even at $15 500 AUD complete with C's changeover ECU, but the Soarer owners wanted a bit of the action also. The original kit didn't fit under the hood of a Soarer so C's went back to the drawing board and redid the manifold to drop it further between the heads.

They use a flat base with a 'box' cut into it to clear the starter motor. It's a complete cast and is very well done. It has tubes in it which enables the M90 to be bolted invisably from underneath, so during assembly you simply bolt the blower to the manifold, then lower the whole thing onto your engine, do up the manifold and you are done.

The kit produces 7.5lbs of boost and will run with standard ECU although the C's one is a lot smarter. It actually uses a small MAP sensor attached to positive pressure on the rear of the manifold. It takes this signal into the ECU and then uses it to control the bypass valve. This means that the perfect smooth shifts that happen as your factory ECU drops the engine momentarily to allow the shift, also drops the by pass valve. The effect is seemless perfect gear changes and off throttle response. Nice touch.

At present I've been fortunate enough to pick up a pristine LS400 and have an Eaton M90 from a USA Ford I believe. I would like to fit it to the LS400 but have been looking long and hard for a suitable manifold for it. Joel may just be the answer.

Unfortunately Joel's profile does not show where he is, but if you read this, could you drop me a line to [email protected] please.

If I can understand how to post images, I'll put some up of the Supercharged UZZ32 and the unit off the car as well so you can all see the manifold.

jordys ski boat & his brilliance again

Rob Here is my almost finnished setup that Joel has been making for me over the last 2 years He is a very clever man indeed
He doesnt live that far from you :veryhappy

 

[uzz32soarer]

Huge amount of work to make all those changes. Clever work eh?

Is that blower from a Buick. All the pipes seem to be in the wrong place. What are you putting it into?

 

[Gazzasore]

No Rob its off a Ford thunderbird Joel said last night that there are 4 on ebay @ $200 buy it now.It going in my Soarer
Joel has gone to great lenghts to make sure its as low as possable
Hahahaha I asure you the pipes are in the right place out the top of the Supercharger through the intercooler then into the Manifold

 

[syagash]

Hi guys,

That set up is almost the same as mine.
My blower,inlet duct and return to manifold are also from Thunderbird.
Im using air to water intercooler, what type of intercooler are you using.
Its great that others are using this set up,the top of my blower outlet dict is
only 10mm higher than standard plenum (fits under Courier bonnet)and I hope to get higher power and less risk of detination with intercooler.
Good to see that you have done your own thing, any others out there like it
that are running?
Im still a few weeks from finishing, will be interesting to see how much differance there is using an intercooler.

 

[Gazzasore]

Im using a small front mount air to air cooler
Mine has to fit under my Soarer (SC400) bonnet theres not a lot of room there

 

[Gazzasore]

Here are some more pic's

 

[jordys ski boat]

thanks for those nice coments Gary it will be a very nice setup when its finished
intercooled is the way to go to make power

 

[Damien]

Very neat design there Jordy. Looks like you've swapped the cam covers??

Rob, good to see you here! To post pics click "Go Advanced" below.

Damien, When I go to add a pic it brings up a window starting with a URL.

Does this mean that I have to have the pic already posted somewhere on the web and then html link to it?

 

[uzz32soarer]

Here's a couple of images of my finished job.

 

[Damien]

Only you would have a spotless supercharger : )

 

[Lextreme II]

Very clean Rob.. Nice....

 

[Muzza_NZ]

wow uzz32, that definitely looks like its supposed to be there! well done

Muzz

 

[Gazzasore]

Rob what sort of KW are you getting at the wheels
do you know how may percent you gained

 

[uzz32soarer]

It went from 132 rw/kw to 178 rw/kw with no tuning and just a mild steel 2.5" exhaust. It's very quiet as I'm partial to sleepers.

I have an SMT6 Perfect Power piggy back sitting here waiting to go on, but I'm all confused by this closed loop / open loop chatter that I don't really understand. I'm looking for 190Kw at the wheels once she's all tuned up properly running at 7.5Lb.

 

[uzz32soarer]

Here's the C's manifold.

 

[Damien]

Rob, closed loop is when the ECU uses the output of the O2 sensors to decide how much fuel to squirt in and open loop is when it ignores the O2 sensors and uses the fuel table with some modifiers like air/water temp.

Open loop only seems to kick in at or close to WOT. However, from my experience with the MAP-ECU, closed loop is still influenced by the MAF signal so it's not black and white.
