Why is you coolant temp so high? Do you run the pro alloy pre-rad? How are your coolant temps at normal street driving? I am working on a Harrop-powered Car at the moment with pro alloy pre-rad and 2nd pre-rad standing at the front of the crash box and coolant is much higher than before... Fans will start at 95 and it is not getting higher. But not cooler, too :-( Cheers Chris

Coolant temps are high because I had only just come in from a 10 min run on track setup the log and went straight out When cruising at 70 mph my temps are quite low around 83-84 degrees I have a full pro alloy setup cc and coolant engine rad with two fans

and when pushing on the road? whats your temp when the fans star?

Fans kick in at 99 When on the road the car dosent get over 90 degrees but I don't really drive bad on the road Unless in traffic

I get circa 30/40 c on power runs. without wi.

 

if this is  the case why are yo bothering with WI 

would be good if you could put up your track data similar set out to the one i posted 

and a power run chris 

 

maybe a base map harrop has cooler temps than one which has been mapped 

[chris_uk]

Its more down to my direct air cooling for the supercharger than anything else., that and im sure the car is running a little rich.

  Thats without CC and airscoop on the roof right? (sorry, couldnt find the answer in your thread).

No, its with a cc and a direct air cooling for the charger.

The best inlets temp data ive seen is from lukes car but this was not done on track and has little high rpm data on it 

 

 

[chris_uk]

As chris said, all the air going into my scoop is channeled onto the core of the charger, the gap gets smaller at the rear of the scoop speeding up the air too.

Here is some of my road data 

 

[CHILL Gone DUTCH]

Also all the data I have so far posted is without WI

No disrespect to anyone but graphs taken on the road while using "cruise" revs are pretty missleading. You need high stress logs over prolonged periods, i.e. track sessions. Even a power run won't tell you the truth about where you are cooling wise.

Just curious... what kind of IAT's are you guys running without WI? (and with cc??) Just to get an idea if I'm runnig hot.  

On track 75 with m62 and 95 with harrop on hot days. Go to my channel and see for yourself. inlet temp is top number on phone.

Check my thread out for IAT graphs on a warm track day at Blyton Park last year. First one without it switched on was getting into high 80s/90s, next with it switched on (straight out of box, not mapped) dropped to high 20s/low 30s. I'd post them here but I'm on my phone at work. Edit: I don't have a big CC rad up front, just a small ear rad which doesn't do much. Sent from my iPhone using Tapatalk

Yep that data is certainly one of the catalyst in me installing mine You have to admit though your is showing them large iat without wi switched on is certainly down to the crap small rad in ear Can you post them here when you get home plz 😜

this is the track session 
ive zoomed in so you can try and follow it 
 

[siztenboots]

from that , could you say IAT goes down with a high MAP?

[CHILL Gone DUTCH]

i think there is a slight delay happening not sure if this is down to the sensor speed

TMAP sensor must have a rise time , temperature sensors are quite bad for that, unless its a K-type thermocouple

  i dont know the type but if i tell you its the same found on turbo model you might be able to answer the question  (stage 4 turbo)
