VERY interesting project coming

[Guigsy]

very much doubt its got a helecopter gas turbine in it :S car looks too small. maybe a model jet engine

Yeah right, I could fit a Gem engine in the boot of a focus.

 

What do you think powers the y2k? First one was built in Derby.

Read all about it here, the turbine is an "APU" or auxiliary power unit, whatever that may be, perhaps a thing to start the main turbine?

His previous car, a Morris Minor was also quite something.

The Apu is a standalone engine compressor and turbine that is used to provide electrics(it has a generator),and air (off compressor) for use on the ground with no main engines running or in air for emergency use (main engines fail)

They are fairly complex and expensive - it looks like he used an air starter which is a kind of turbo compressor used for starting gas turbines -

Eventually help in the form of respected engine tuner John Beattie came to hand with the arrival of a 1700 cc Cosworth BDT. Canted over at only 25 degrees to the horizontal towards the intake side, this satisfied the requirement of minimum centre of gravity and minimised the frontal area and yet still left room for the driveline forward. “With 400 bhp the initial aim, it was evident that a move to a larger turbocharger and quite a large amount of boost would be necessary,” says Mann. “This would result in the dreaded turbocharger lag and while anti-lag or ‘bang-bang’ systems were considered, it was quickly decided to move to a much more radical solution.” Mann’s background in aerospace led him to a solution involving a helicopter gas turbine APU or auxiliary power unit. Supplied by Turbine Technologies Ltd of Carmarthenshire in South Wales, the unit is based on a helicopter emergency air start unit used to fire the main gas turbine engine on the ground.

Running separately from the main engine, initially on diesel fuel, the unit delivers air to the engine at a constant pressure independent of the main engine speed and hence totally eliminates the throttle lag normally associated with high boost turbocharged systems. Currently set at a very “modest” 25 psi gauge boost, the engine delivers something in the region of the initial target of 400 bhp at 7500 rpm. The torque curve is particularly impressive: from 2500-7500 rpm this doesn’t vary by more than 20% from the peak value."

Wonder how one of these would work for spinning up a large tubby http://www.hobby-zone.com/p_engineslist.php?type=turbine

I think the maintainence interval may become a bit of a pain

And the heat given off.

[Wez]

I was thinking more of driving the exhaust side not pre turbo. The heat would be a good thing

Don't think I would like that Wez sometimes its nice to have no turbo !!!!!

[Wez]

It would be infinitely variable as you could control the boost via the turbine, I think it would make an interesting project

Any more news on this Dude?

Still waiting for parts, should of been here this week, no sign yet:(

[TLicense]

Nic Mann's "Mannic" hillclimb car uses some interesting technology that *IS* proven to give totally lag free turbo boost. Google Nic Mann and Mannic to find plenty of info. Here's a clip of it in action. I have seen it run a few times and its acceleration is brutal.

lol, didn't know Nic was so well known. I used to work with him years ago when I worked for a company designing and building MRI body scanners.

Nice bloke.

[jagman]

Bits arrived ,so phase one begins;

 

firstly dyno numbers and data as is ;

single turbo T67

800 injectors

fmic

walbros

blah,blah

 

 

Phase one

fitment of water tank and charge cooler system

It has been talked of before but I have not seen any actual fitment or data on a charge cooler on the supra , so lets see.

At first it will be in conjunction with the fmic , sort of belt and braces , and fitted post fmic , not the ideal situation but for now pending stages 2/3/4 good enough .

the charge cooler has a very small pressure drop 0.1 psi , so wont drop any significant boost but should give very stable IAT temps under high boost , its rated around 400 bhp worth of cooling

The water tank 21/2 gal can also be ice filled if necessary for short term cooling at below ambient ,again lets see..

Im sure Dude can supply pics as and when hes done the instal

[dude]

As we discussed Adam I don't think its worth going OTT on the install because if we end up deleting the FMIC I want to move the CC to where we said.

You designed MRI scanners? I knew you were a clever chap Tony, but wow!

[Gaz6002]

ST205 charge cooler or bigger?

 

EDIT: 12,000 posts. I am one sad man.

[jagman]

No its a barrel type CC , and controlled by an adjustable water pump with the controller in car to allow adujtment for test purposes - this gives flexibility in instal positions

[JamieP]

Im very interested in a charge cooler setup, would love to run one inline with the IC myself.

Water Cooled hybrid FMIC.

Or Full on charge cooling.

[JamieP]

Speedmax looks interesting, im not interested in the full on chargecooler setup.

[Miguel]

Yeah, the full on is a bit pointless on anything other than a drag queen. There's a few barrel type coolers that may be more along the lines you are thinking. A few of the US lads have run them to varying degrees of success.

[jagman]

There is an advantage with each method air or water , but a balance in using both , recovery times and lower pressure drops

It may end up best using the stock sidemount with it's advantages combined with a CC -

Data is the important thing at the moment
