ct26 output temps and ST205 CC efficiency

[stevecordiner]

A fella over in the US has done some tests with the stock ct26 (note this was a fully forged engine).

""test car/mods listed here: http://www.chicoraceworks.com/gallery/ben93smg

@15 psi compressor outlet 'peak' temp was 150 degrees F
@15 psi throttle body inlet 'peak' temp was 65 degrees F

@1.9 bar compressor outlet 'peak' temp was 290 degrees F
@1.9 bar throttle body inlet 'peak' temp was 90 degrees F

this was all done on a very cool evening when outside temp was approximatly 50 degrees F""

In our money thats

"Ambient - 10 degrees Celcius

CT-26 Temperatures

@15 psi compressor outlet 'peak' temp was 150 degree Fahrenheit = 65.56degree Celsius @15 psi throttle body inlet 'peak' temp was 65 degree Fahrenheit = 18.34 degree Celsius

Intercooler efficiency - 48 degrees reduction in charge temps

@1.9 bar compressor outlet 'peak' temp was 290 degree Fahrenheit = 143.34 degree Celsius @1.9 bar throttle body inlet 'peak' temp was 90 degree Fahrenheit = 32.23 degree Celsius"

Notice that the ST205 CC manages to pull a 112 degrees reduction in charge temps!! That is immense!!

I am ... but suprisingly enough I dont work with temperatures haha.

Can you sort the lower half out so its readable !

Its an engineering / geeking thing ! Have to proficient and converse with all measurements ! You wanna see the big L shape on my forehead at present !

32 deg F @ Zero Deg C
212 deg F @ 100 deg C

Whilst this is superb information, I like to see is not a modification to fit a chargecooler, but a reliability improvement ... keeps the mpgs down too if your a mieser / accountant ! **cough**

[SFLee]

or for ur info

F= 9/5 C +32
C= 5/9 F -32

Hehehe ... meiser? Thats a bit harsh - I prefer the term Thrifty lol

that's pretty impressive figures there and he is using the original intercooler as a radiator. Bleeding norah!

1.9 bar on a Stock CT26...no wonder there was so much heat...would have been like a hairdryer!!!!!

What about power figures with those temps? Wouldn't a CT26 @ 1.5 bar be more efficient then @ 1.9bar?!

It must have had some sort of oil cooling too....sorry not read the link......too lazy!

Blimey, I should have patented that !!

Catching on using that ! Sure he hasen't got a tank somewhere dipped into his air con pipes !!

Hedgehog, they just did this for testing purposes to see what sort of heat the ct26 generated. By the red line boost had dropped to 0.5 bar lol

I must admit I'm seriously impressed and debating whether or not to go front mount. Choices choices

LOL. I've done this too (stock IC as rad, but with a bigger fan). Hopefully, will have some data in the next few days.

The one b!tch of doing it like this is that the system is a pig to bleed, but if you use your nod, it can be done quickly although it's a bit of hassle.

put it in the boot and stop going shopping!!!! Awesome!!!

0.5......HAHAHAHAHAHA quality! Good temps from the CC though

What's needed to make the original I/C a radiator in a system like this ?

Weld up the inlet and outlet to the intercooler... stick some 3/4" OD diameter nozzles on it.. then jobs a gooden.

[stevecordiner]

Maybe I should just be a show off and use the stock IC as well as a front mount lol

[JJ]

Take it from me... go for front... the side mount couldn't handle a 15 minute abuse I gave it last summer ! though... ambient was 25 deg C !

I'm not surprised though !! if its trying to pull 100 deg C + out of the charge temps, needs a better cooling medium or more circulating water !

Don't get me wrong, it wasn't boiling away, but it got to the point where it was turning into a hot bath

[JJ]

but if you use your nod, it can be done quickly although it's a bit of hassle.

I have no draining mechanism on the side mount !! No loaf used there !!! In my defence, I just ram in the new stuff via the pump thats a different colour to the existing water / coolant and just leave one of the nozzles off for the CC until it starts runnign blue or red !!

Thats what I was thinking of doing... have the side mount still cooling whilst in static traffic as you wont' be getting any driven air into the front rad whilst your sat in traffic... unless your running your air con ( kicks fan in at slow speed ) or fr1g the wiring so you can have an overide on the front fans... when idling or sommat ( throttle closed ? )
