What kind of air temperature would I be expecting to see coming out of the snail of the turbo??

Carlsworth

you d be looking around 600-900 degrees depending on driving

Red16

think he means the compressor side not the turbine side

Lee_R21Turbo

iTrader: (1)

Sorry, yeah - compressor side!!!

Carlsworth

ah reet,....

its early....


in that case, its around 75 degrees

GARETH T

depends where you are on your compressor map

if you got your turbo compressor map, know your boost and know got a dyno printout,,, you can work it out

Carlsworth

ok ok smart arse

but roughly......

foreigneRS

impossible to answer without more information. easier to just measure it, surely?

Lee_R21Turbo

iTrader: (1)

Yes this is true mate, which is what I'm planning on doing.....I was just checking that the temperature range of the gauge I was looking at (water one) was adequate for this use!!!

GARETH T

what turbo you running, how much boost,,, what car?

Mike Rainbird

iTrader: (3)

110-150°C turbo and boost dependant.

Carlsworth

edit,....forget it....

Only a lowly T3 with a cossie 0.48 rear housing, 18psi at the mo but maybe 21/22psi if I get the parts I need to do so!!!

21Turbo....OF COURSE!!!

GARETH T

you'll be well over 100 degrees

Lee_R21Turbo

iTrader: (1)

Cheers mate - ah well....least the gauge will be well within its range!!!

foreigneRS

agree with mike and gareth t - well over 100 deg on a t3 boosting at 22 psi

As above, a water one probably wont be any good if you are measuring pre-intercooler as you could see well over 100 degrees which obviously you cant with water unless its a guage intended for a very pressurised system, most car gauges stop by about 120-140 or so that ive seen and you could easily see more than that on the ragged edges of the compressor map (where most t34 cossies are ran hence the rs500 coolers being so popular, lol)

Also, water temp senders tend to be more heavily encased in brass than air temp senders from what ive seen (although will be make dependant) so you may find they dont react quick enough to be useful as water temperatures typically change quite slowly but ACT can change in more or less an instant.

GARETH T

depends on what type of water gauge,, the responce time might not be quick enough

Chip

iTrader: (3)

Indeed, speed of response is as important as range, in the case of water senders you acutally dont want mega response, they are deliberately damped y their mass as the gauge could easily end up flicking around otherwise to a greater extent than is useful.

Lee_R21Turbo

Yeah, totally understand what you are saying guys.

Gauge goes upto 150deg C - worth a go really - only really interested in what the temp is at full pelt round a track (so its got plenty of time for the needle to rise after a few hot laps!) & how well my intercooler's coping!!!

I've already got a water temp one & its included in the package I'm getting so might as well try and get it to do this!!!

Chip

It should be pretty useful if its the peak figures you are after like that mate rather than an accurate graph of what happens and exactly when
You may just creep off the end, but im guessing that isnt going to be a problem for the level of accuracy you are after.

Dont forget to post your results back here

AlexF

Lee,

Just use a thermocouple and a simple gauge

Alex

Exactly right mate.....I'll come & personally tell you after a few laps of the ring!!!!

Chip

iTrader: (3)

Any chance of a passenger ride too while you are at it mate, as ive never been in one of those things used in anger in that sort of environment so im interested to see how the "legendary cossie killer" gets on

Why not use something like this:

Sure thing mate - people that have been out in it before (Ring & Donington) were I think pleasantly surprised at how it well it goes, it struggled a bit I feel in some of the uphill sections of the ring but I might be running slightly more power if I can pull off some of my plans which should help!!!

"legendary cossie killer" it aint - but it certainly seemed to keep up with a few at Dono!!!

Turbosystems

iTrader: (5)

100C -170C depending on boost and ambiant air temp and time base

Turby2

Nice little gauge

Not cheap though at £405!

Sounds good mate, im looking forward to it
