Intake temp after i/c discussion

[bazeng]

Hi guys,
I'm just wondering what intake temps everybody is getting after the i/c...

I'm getting 20 degrees at idle on a nice night (prolly 15 degree's ambient)
it goes up to around 60 degree's Celcius at full boost...

This is with the pwr water to air setup..

Not sure if its good or bad..
on cold nights it gets down to around 6 degree's C off boost.. haven't checked when boosting yet..

thanks guys!

(MEASURED WITH A WOLF3D TEMP SENSOR BEFORE T/B)

i use to see 60 just before the TB, ambient somewhere around 30-40
Boost set at ~17psi on s16g - std JSpec cooler
:roll: :roll: :roll: :roll: :roll:

how do you check?

when i fire up MADEVO again i will tell u baz!!

 

[WRCVR4]

how do you check?

I useto have a simple digital temp guage probe in there :roll:

mines 25 degrees on full boost just before the tb.

I measured it on friday when i was re-doing the tune, got up to 45 after the car had been sittting with the bonnet down for 20 mins, but it came down pretty quickly once i gave it another run.

60 seems high.. im running 18psi @ 6.5k(creeps from 15ish) by then

 

[bazeng]

mines pumping at 30psi...
45 psi is like normal..

any other numbers guys?

talk to darren (trikfab) about his dry ice box

he said minus temps for them

 

[matress]

mine consistently runs at -46 degrees 8)





but thats only coz the air temp sensor isnt connected :lol:

 

[bazeng]

haha matt
get one in next time ur at rank...
not hard to install..

u just need the bung to get welded on your intake pipe...

as for the dry ice box, yeah i'll be doing it down the track..
i've got a few idea's..
i might use my original heat exchanger, weld that into a sealed box and use the radiator as the dry ice heat exchanger...

Baz, what fluid are you using and how is it pumped? Can you adjust the pump speed and does it make any difference if you do? It sounds like the heat exchanger can't transfer enough heat into the coolant or that the coolant can't be cooled sufficiently. Maybe chat with Aldo as he has played with stuff like this.

 

[bazeng]

i've tried a few things but honestly, i think plain old water was the best
i've tried a tiny bit of coolant + water (to stop any type of corrosion) and i dont think it worked well, it may have improved the boiling point but not absorbtion of the heat

any suggestions??

 

[rob323]

I know it would be a pain in the ass but it would be interesting to monitor coolant temps before and after both the heat exchanger and the radiator/condensor (what ever it is you are using for this) to see what is and not working efficiently.

My car In the past week. figures from microtech hand controller
tonight it sat beween 18-20 degrees
A few laps of wakefield park saw it rise to 29
the lowest I've seen it, 7

Besides loss of power, Can the motor be damaged by running over a certain temp?
I know high intake temps can cause detonation but I'm not sure at what temp detonation may occur.

 

[bazeng]

where are you measuring the temps at?

i should buy one of those infra red temp probes..
anybody know where to get them from?

When mine was on the dyno a while ago it was a 35' day and i was having inlet temps of about 40' - 45' @ 20 - 22psi (using motec inlet temp probe about 5cm before the TB)
When i saw that i thought that my cooler must be good at cooling but **** at flow, so i connected a boost gauge just before after the turbo and compared it to the one i had in the plenum and there was about 1 - 2psi difference at 20 - 22psi so i guess thats not too bad.

Thank you
Jason

The sensor is about 5-8cm's from the throttle

dick smith or tandy for the infa red temp gauges they are xpensive but
