50\'c+ Intake Temps

[Rixio]

But just by touch it feels sooooooooooo hot after its been sitting for a little while...put it this way, came home last night at 2:30am parked it up bonnet open in the garage. Went inside had some munch, brushed the cats...went back out to close the bonnet & the garage is litterally hot inside! Now this is a 2 story double garage plus extra space, so its gotta be giving off some serious heat.

You cant touch the plenum its that hot! Even after 45mins!

Moving intake temps drop to mid 30\'s and water temps solid 85\'c...

i know what you mean about the garage being hot, mine does the same but its a bit smaller.

You should try and maybe shield the upper inlet somehow,  i have seen several people do it with bits of ali.

It wont stop your garage getting hot though!

Your a star! What did you use to cut it?

[Adie Moore]

just a jigsaw with quite a fine blade. cut from the under side and just followed the shape of the cross braces. finished off with a file and then went round the bare metal edge with a brush that had been dipped in to some spray paint. I went slowly as one of my aims was to not need to get it re-sprayed, which i didn\'t.

Sweet...i got a dremmel the other day so will have a bash with that as soon as i get a spare bonnet! 20\'c intake temps here we come :evillaugh

Just to stick the boot in my intake temps have been as low as 6c on full boost in the winter. Yes she is a 12 months of the year Fd, nutter I know but thats me.
Looking at you intake filters you are just sucking in hot air from one as well thats not helping, thats why I got the copy Scoot bonnet and did my intake mod and the hot air can get out all the time via the openings.
Through the summer my intake tems coming off track after 30 mins of WOT have been in the low 30\'s at there highest.  Just driving around on the road then 17-23c. Water temps have never gone above low 80\'s, normal is 70-75c.
I have yet to seal the rad & intercooler gaps and rubber seal the bonnet to my intake mod. These will be done this winter. I also plan to put an adjustable Ali plate in between the V ( ---> ) of the Rad & the Intercooler on an adjustable threaded bar so I can alter the Rad temps/ Intake Temps by moving the plate up or down on a hindged system.

Think you are suffering from a heat soaked sensor, it wont echo intake temps correctly and therefor i susest relocating the sensor to the elbow, Also strip the plastic coating from the outside of the sensor till its exsposed then it will respond quicker and represent intake temps a little closer.

Similar to the idea I had , I was just going to make 3 plates that could be swapped out when needed , threaded bar might be a better idea though , more adjustment and probably quicker , might borrow your idea :cheers

personally i wouldn\'t cut the bonnet open. It will look sh1te, let all the rain in, make the engine dirty quicker and also be a weak spot for thieves wanting to rip the alarm out. A better idea would be those bonnet lifters that raise the bonnet from the hinges about 1" Only trouble is this looks crap also

This doesn`t work as well as most people think. The air at this point is very slow moving if not totally still caused by the flows interface with the windscreen. This is the reason the intakes for the heater etc are here as they can draw this air in easily, If it was flowing fast they wouldnt be able to draw the air in. Anyway as this air is not moving it does not draw the hot air out from under the bonnet and in some cases can even raise under bonnet temperatures. Due to causing some sort of pressure difference (can`t remember the specifics off the top of my head but you get the picture).
 
Bonnet vents should also be shaped a little like a ramp to help create the pressure difference that draws the air out. Just cutting holes in the bonnet does work but is not as efficient as properly shaped vents.
