SUMMERNATS 2008 HORSEPOWER HEROS

	Note  1
Third - Gary Pope - BLO 402 - 1529rwhp	First - Craig Munro - Try Hard -   -1895rwhp - note almost overlay of back to back power curves	Second - Lyle Lemmon - Mr PSI - 1713rwhp

Note 1 - the sudden drop off in power at 192kph is a boost loss issue that is suspected to be blow off valve related, as the valves control the boost - now being changed too waste gates control as mid 30 PSI is the maximum boost available with the setup as run here ! The run was on track to make even more power !!

The above three cars have a number of things in common.
All the above graphs were achieved in a room @ 36°c & are rear wheel horsepower.
They are owned by dedicated enthusiasts.
They were mostly built by the HorsePower Factory www.hp-f.com.au  - overseen by Rob Vickery.
They were all tuned in house by Amberley Autos www.amberleyautos.com.au
Their intercoolers were computer modelled & then fabricated by ARE Cooling .
The owners are now much poorer than before they started.

WhaT'S the big deal with this car ?

   M A Y B E     2000hp  (1500kw) ???
Please note that this is what our system is designed for, what owner - Craig Munro www.hphero.com would obviously love to make, what crew chief -  Rob Vickery is aiming for & what we're all hoping Amberley Autos/Horsepower factory www.amberleyautos.com.au  Marty can tune this beast to. The biggest worry in this equation is the Pump fuel - 98 ron. I have no doubt in my mind that these power levels are obtainable with C16 or equivilent, but optimax is going to take an exacting level of tune & cold charge air.

            M A Y B E     T H I S     ! ! ! 
Note that hoses are colour coded throughout the car.    Red is Heated water.  Blue is cooled water.

Equal amounts of chilled water into both sides of the intercooler.	The blow off valve is nearly as big as some cars turbos !		This is the ice chiller. The boot is the only area big enough to hold enough ice to absorb the heat from the front a-w. ic.	This is the underside of the ice chiller box lid. All hole positions & sizes are calculated - not guessed.
I reckon the unusual mix of speedflow alloy AN fittings on SFS silicon hose, that we pioneered, looks real trick.	Cold water in the blue hoses in & hot water out the red hoses out.		4 DC. engine water pumps push minimum of 180l of chilled water up to the engine bay.	3 SX fuel pumps push fuel up to the engine, Thru our ice chiller sump.
Definitely not your average cooling system. Curved rad- iator is to allow air from 3 fans to escape.	We used a mixture of alloy tube & silicon hose for best water flow.		With the cover on you'd never know what's underneath.	These three D.C. pumps are to recirculate the ice chiller water only. Need 150 l / m. flow.
3 silicon hoses in centre carries very cold water & single hose on right, bloody hot charge air.			When the side skirts are fitted, this is all that can be seen to get 180 l/m. of water from the boot to the engine bay.	The side pipes had to be welded in an oval shape to allow the side skirts to fit.

A six page PDF file

This is the first stage of the project.   It is the  PDF file of our ARE computer programme sent to Rob & Craig with the projected results of the system we designed. This was July '03. Not too long now before we know how accurate it is! We use a ±5% allowance with our temperature. Please note: There are hundreds of lines of calculus that are hidden in our programme & the solid coloured cells are to prevent cross referencing of data in different files on our site. There's more here than I should give away  anyway.

	This is the second stage before we attack any alloy. Cardboard templates to make sure it's all going to fit. As it turned out, the top two matrix had to be reduced because of a four mm. interference that we could not get around
	These are two of the eight core matrix used in the intercooler. They are our brand new tube extrusion that delayed completion of the car.
	They may look straight forward, but there is a  total  of at least 25 hours work in this tank , & both would have to be different !
	It took 3 times on the flow bench to get the distribution pattern I wanted Yes, it does cost pressure drop, but the cooling gain far out- weights this. Every joint is double welded for strength. The start position & profile of the baffle is most critical.		This is the battery box we had to fabricate.
	Seamless transition from the mandrel bend to the tank roof. The external fillet weld pattern is left  because it has nothing to do with performance & can't be seen. There is a limit to wasting time.		Craig wants to be able to take his mates for a skid in comfort & wouldn't let us run 2x2½" water pipes through the cab, so we had to do this. Added a few grand to the price, so I hope his mates enjoy it - they're eyes will be tennis balls
	Nothing about this job was straight forward. Maybe a spray pattern is overkill, but it all helps.		These are the fuel pipes running through the ice box sump for extra cooling.
	This sucker should remove 410kw. of heat out of the intake charge. The air speed thru each inlet pipe is 205 kph, but we've got it down to 29kph thru the core !!
	The water out of the two bottom cores, is going to be at a minimum of 104°c ! They will remove 79 kw of heat each. Note: the last 2 cores (top) only remove 8kw each.
	The pipe shape is to fit everything in Same for cutout in water tank. Id of every pipe is calculated for the right flow rate.
			Shows the curve we had to put in the Radiator core to fit in the front This car has to cruise!
			So naturally the fan shroud curve had to match.
	When I saw this on my welding bench, I just had to nick name it 'the fat arse cooler'  ! It wouldn't  fit into even my pants.		Finished fan shroud-fan assembly. 3 x 14" DC. fans provide 3324 cfm of ambient air flow. Oh, be wary of some of the figures claimed. We've tested heaps  !!!
	These are just two of the many pipes we had to fabricate for this car.		Some of the work we had to do on the thermostat. Yes it has to run one - definitely! Same as every modern car. Since alloy heads came in.
	This is the bracketry we fabricated for the intercooler bottom mount on to the chassis rail. It has to support a dry weight of 48kg.		Finished thermostat ready to fit.
