Andy's car started first time after 3 weeks in the workshop. Pulley size was a conservative large size giving 3 psi. He will machine it tomorrow, making it smaller and giving 5.5 psi.

On the dyno the torque curve was nice and flat - good increase down low and not dropping away up top like before. Power peak has increased by about 700 rpm.
Boost was a constant 3 psi from 900 rpm to redline - no need for blowoff valves or wastegates on a positive displacement blower - it delivers perfect boost the whole time, no more no less.

3 psi doesn't sound like much, - and it wouldn't be on a small, low compression factory turbo motor, but on a high compression 4.0 V8 the difference is noticeable. Grunt off the line has improved so that for the first time dry road straight line traction is an issue. Kick down to second gear gives that deep seat thrust.

Andy is still running stock airbox and standard headers. Car is still smooth. No lag, no progressive power build up - just more power everywhere.

Still running stock ECU, no water injection yet, no timing control yet - rising rate fuel pressure regulator only.

Please, Please, Please : Keep us posted! (you're doing an awsome job already Pete!)

Sounds like there is good hope for the 400 and it's coming quicker than I expected. Any idea when he'll hit the dyno?

Is he keeping a running list of all the necessary parts?



Keith

He has dynoed once - big torque increase - going again soon - his workshop has a dyno right there. He is keeping track of all the parts.
Andy also worked on the 7 litre V8 Monaro (soon to be imported to the US as GTO Pontiac or something?) that won the Bathurst 24 hour race last weekend beating Ferrari and Porsche etc.

He helped assemble the heads, install manifold, and do first dyno run on the car. Intake Manifold = $14,500, Block only = $15,000
Rods = $3500 etc.

The V8 Monaro is here:

After Andy started his blown SC400 the first you do is go for a cruise around the block - sounds great:

Hello Peter,

Thank you for the wonderful news. The M90 is widely use in the US automobiles. I was wondering which rising fuel pressure you are using? What is your Fuel pressure at 5 psi?

Currently, i am running 5 psi also with twin ceramic bearing T3. Boost start around 1600 rpm and reaching 5 psi at around 2500 rpm. I am using Apexi S-AFC as a piggy back. My car is NOT running perfect yet. More tunning is required.

I got Walbro 255 L/H fuel pump and an Automotive universal fuel regulator ready to install. I plan to run 9 psi along with alcohol/water injection. I am getting some used 440 cc injectors from Supra TT MKIII. I dont want to run 9 psi unless everything is working properly.

Please keep us inform.

Thank you.

This is pretty cool to see some pressurized motors working out so well.
Keep up the good work.
Healerhand,something happens in the way of a rapid buildup of heat at much over 6-7 psi,so don't be surprised if your tuning gets more touchy around there.
Any good kills?

Don't know about the fuel stuff - I'll ask him next time.

Aren't the Supra injectors side feed instead of top feed like ours? Will you have change the fuel rails?

In the above directory is three small mpegs of Andy taking off and smoking the wheels, on the dyno and driving by. This is about 15 minutes after starting it for the first time, 3 psi. No way does my V8 take off like this!

It's gonna be great to flip the bonnet and see one of these.

I did ask if there will be an optional spacer plate available to raise the height of the supercharger so that half of it would stick through the bonnet (get another second hand bonnet from the wreckers - plenty of green ones around!) - but no-one took me seriously! I mean they filmed MadMax just up the road from my place and now and again I need the supercharger to poke through the bonnet!

Hello Peter and All,

Supra MKIV (93-98 year model) is side feed injectos, but the MKIII (previous model) is top feed. I am not sure if it will work or not. I am doing a trail and error. Currently, not too much information on 1UZFE peformance, i have to do it myself.

I called both Toyota and Lexus dealers and they all dont know. I asked questions in www.supraforums.com and no one have the knowdge of the interchangable parts.

I think one of the reasons my car is not running perfect yet is because i have oil flooded my turbos and a lot of oil went to the intake. I cleaned out my MAS, but i think i need a new one. Secondly, i think my spark plugs are flooded too.

I will let you know if work or not. Please ask Andy the fuel pressure. Thanks

Andy is going to 5 psi this week.

Hello Peter,

I just installed the water injection system last night. Currently, i am just using distilled water. The injection is set to come on at 4 psi and the current setting is 7 psi. I saw 7 psi last night when i was testing the system. I made a few runs to set the water activation switch (boost sensitive). Finally, set it to 4 psi. The car feels much smoother with H2O injection. Fuel pressure is stock. Only thing changed was the piggy back computer.

anymore updates on how 5psi went? if it went well, i figure you'd be humping his leg by now!

if a kit came out, i think i'd be humping the other leg.

The M90 is nice, but the M112 would be better for upgrades in the future. Currently, the 2003 Cobra uses M112 (MP112 is a modified version) the slightly mod(Chip, Pulley, Exhaust) cobra is pumping 500 rwhp. With M112, the LS and SC can easily achieve 450-500 rwhp.

Andy has been too busy with his regular job and other stuff - the Soarer is still faultlessy getting around with 3 psi no problems at all.
Still with stock airbox and stock headers!
Only other mod is a rising rate fuel pressure regulator.

So far sounds like the most impressive bit is the low down torque gain. He now runs with the Twin turbo Soarers, and then some, quite comfortably.

He has machined a smaller pulley to increase the boost but hasn't had a full day to install it yet.

I won't see him until the Jan 11th 2003 weekend - dyno shootout Saturday, Big cruise on Sunday with lot's lots of cold beer and steak! (It's summer over here).
There will be alot of pressure on me since I am reigning Horsepower Hero from the last shootout - even beating a Twin turbo! (my mods were intake, headers, xpipe, exhaust, modded exhaust camshafts, high octane fuel) - luckily for me some of the known high horsepower Soarers chose not to run saving themselves for the big Jan 11th day - but a win's a win!

Anyway when I see Andy we will do a comparison - we both have UZZ32's - I 'll take some AVI's of us at stoplight drags to see how much more grunt the supercharger gives over traditional N/A type tuning.

Rob will talk to Andy about the business side of things - I reckon they will get the intake manifold and throttle body connector cast so that anybody can just bolt the whole lot on an SC400 over the weekend with your mates and stand back - but that's the future - I'll know more about how things are going after that weekend.

I've done the intake and exhaust - now have large slotted rotors, EBC greenstuff pads, stainless brake hoses - got the new tyres on 18 inch forged rims, new bushes and wheel alignment - hmmmm - only one thing left to do.........

I have got my turbos up to 8 psi on stock fuel system. I think Andy should change to a smaller pulley (8-9 psi) and run methanol injection as a intercooling source along with upgrade fuel system.

Well I drove the car with 3.5 psi. Still standard ECU, airbox and headers. Was punchy of the line compared to mine.
It's over fuelled - looks like a twin turbo with the gas down because of the exhaust black smoke when overtaking.

So in the afternoon we BFI'ed it and fitted the smaller pulley giving 5.5psi.

It was a stinking hot day. Car went harder but still a way to go. Next is water injection.
Then ECU upgrade giving timing and fuel control.

Andy has just got a new job with the performance arm of Holden (GM) over here - spends a lot of time at the test track. By the sounds of it he hasn't had time to scratch himseld let alone spend time on the Supercharger. His Active suspension is playing up too so there is yet another thing to eat up his time.

So we aren't any closer to a kit - it's still his daily driver and all that, but he's just one man juggling a bunch of stuff.

The pic below is pulley change time - only takes a minute - so you can swap them and dial in different boost real easy.

Andy's moved a bit since I last saw him. The new pulley gives 5 psi.
Stock ECU
Stock headers
BFI
No water injection

Approx 40% increase in peak power and 40 % in torque across the whole range.
I reckon he is going to do some more this weekend.

On the dyno power has gone from 162 hp at the wheels to 230 hp at the wheels. Have a look at dyno graph below - it is not just peak gains, he is getting great gains everywhere - check out the torque increase - at last the SC gets of the line with no waiting. He has the UZZ32 model with engine powered suspension - this model is always down on power compared to other Soarers.
I like the big fat torque increase and power increase everywhere.
He has also done some more work re: kits. Looks like he is going to go for 5 sand cast prototype kits first (hopefully I'll get one of those!). He wants to do some ECU tuning as well.
More to come.
