Bob, its funny you should say that!

Since we fitted the Pace (with new rad), I have noticed that the fans ARE employed more often, not though all the time.
The dash gauge does show 'normal' as before the upgrade, but even in the winter (thats when we fitted it), the fans come on.
I put it down to the fact that the new fans are 'louder' when running and thought that maybe the o/e fans were on as often but couldnt hear them.

I have had the pleasure of sitting in quite a few 'jams' and in summer heat, it hasnt yet missed a beat (crossed fingers).

I am hoping to get some defis or similar at a later date, maybe I can get water temp in that.

If I put another thermocouple in where do you suggest? top of rad, bottom of rad?

AndyF, If (when) I get to take the engine to bits, I will look at the insulators.
I did see that post re this a little while ago, was it stevieturbo in N.Ireland?

Cheers all.

Well, I finally got round to it!

Fitted my temp gauge and thermo couple (saw RB5Scotts on Friday)

Ambient temperature of 19deg (c), went out for a test....

Started seeing temps of 22deg then a bit more 'performance', temps up to 24, 26 and a quick 'rally stage' saw temps of 32deg.

I dont know if thats good or not ???

Back to 'normal' driving saw temps back down to 23 and 24deg.

Then when I parked up the temperature started to rise....59deg and rising

Any comments?

 

what this intercooler is what make?


reminds me of the temps i used to have with my scooby. albiet with my aps the max i got on the road was 28degrees and on track 32degrees.

the temps with teh pace intercooler are slightly higher though.

 

Depending on which intercooler the temps are in the ball park, I run an APS and see temps at or on ambient on fast cruise (ie no rise), no more than 8 degrees (more typically 6) on hard boost (up to 1.4 bar) to circa 7k.

When parked the high temps you see are heat soak, think on ... how many times have you been parked up or in traffic and then blasted away ... charge temps like that make for det ... its a good idea to wait for temps to drop below 30 degrees before using boost under those circumstances

 

Thanks for the response lads, it is a Pace fmic with the standard turbo (TD04L).

I will now at least be able to 'keep an eye' on things, and as you say Bob, heat soak it is amazing to watch that display rise and rise!!!

Off to work tomorrow so Ill be able to do some 'proper' tests.

Cheers all.

 

Sam,
you say with the new pace intercooler the temps are higher.
Isn't this a backward step.
unless of course you have also increased the boost pressure ?
which would make more sense !

 

I think Sam was talking about another person's car fitted with a Pace, not his own....he's temporarily defected to the 'dark' side anyway
Thermal insulators on the manifold can reduce the heat soak by approx 90%

 

I have noted that the Pace causes coolant temps to rise above the norm, looking at the dash guage doesn't tell the story, so make sure that it is ok (select monitor will confirm), I'm told that you should fit extra ducting across the top of the intercooler and rad to make sure that enough air gets thro the rad. otherwise temps run well above normal, certainly I have seen cars running with coolant temps in the 90's with the fans on virtually all the time when they would normally run in low/mid 80's.

cheers

Hi Bob,

Did whoever told you that running extra ducting was a good idea give you any further information as to how best to design this ducting?

It would be interesting to hear of other approaches to this, as I have been considering this for a while, and, when I have found myself a suitible material for prototyping the ducting, I will be building a "box" around the I/C and rad ala WRC97 and WRC98 designs.

Yes please, I'd like to see that

As long as its not too heavy

 

Hi Moray, Pace recommended this to one of my "cars", I will see if I can get some pics of what was done, they just said to fill in the gap (ie box it in) between the intercooler and the rad with "something" to stop the air escaping and force more thro the rad, think aluminium sheet was used but will see if I can get hold of pics.

 

Thanks Bob. Sounds pretty much like the system I was going to build for myself... ala WRC design. I would certainly appreciate a look at the pictures if you do find them.

I recently fitted an HKS FMIC and noticed that water temps went up around 4-6 deg depending on circumstances.

However I completed the mod by removing the number plate and bracket completely (I have gone for square plate - Evo style) and also removing the lower air dam. This has reduced the water temps by around 4 deg - as well as releasing around a third of the surface area of the FMIC greatly improving it's performance.

If it gets too bad on track will consider removing the air con matrix - will also save 30kg and get faster drag times

when I had the prototpye pace rad made, I insisted on them fitting bosses for thermocouples in both end tanks.

I suggested these make it to production. The same was supposed to eb done for the intake pipework both before and after the heat exchanger, and I also suggested a boss be installed for receiving a water injection jet just before inlet into the throttle body.

How many of these made it to production?

The pace has its advantages, specifically the fact that it can be removed untraceably, but for all out performance i will be cutting a new carbon bumper I bought and running an HKS fmic.

would have considered the aps but it was significantly more, the shape of the pipe work (most of which I am wasting) was not as convenient, and also I would not be happing running silicon hoses at 2 bar. I knwo it can take it but I dont like the expansion it exhibits.
