[Loxy]

Yep I've had similar to Dragonfall this week. I didn't have the display on at the time to see whether it was limiting boost but it did almost feel like I was driving with the handbrake on.

Not massively impressed on a pretty much standard car.

Chris posted some interesting info regarding this matter over on TRO

Indeed. Looks like some tactical upgrades might be the way forward.

[Dragonfall]

Excuse my ignorance ... What's TRO?

Is it possible to have a link to the info on there?

Thanks

type R owner club
has chris got a user name im looking but cant find anything on there any link would be grateful

[dweezle]

Its Chris,
The Oracle of Honda knowledge he knows more than the dealers, his info was much appreciated leading up to 1st arrivals, what they call a proper fan boi

Bear with me on this as it does relate and sort of makes sense of this issue.

Last Sunday 3 of us with FK2's drove the 16 miles from Peterborough to the Mimms meet at Rockingham Raceway like nuns. This was at 8:15 in the morning with an ambient temperature of around 20 degrees.

At 10:15 some guys wanted to see the engines, I opened my bonnet and damn near burnt my hand on the rod that holds the bonnet up very nearly 2 hours after turning the engine off.

There was a blast of heat from the engine, the intake pipe above the turbo was bloody hot along with the turbo heat shield. Another guy did the same with his and his was just like mine.
We turned the ignition on and the oil and water temps were still really high (40degrees+).

My journeys today were short city runs for 2 1\2. Hours in total with 1/2 hour stops and then back into traffic.

The engine bay on the FK2 does not seem to vent heat even when stationary, couple this with high ambient temperature and it must get crazy hot in the engine bay. The location of the intake surely means it's sucking this nuclear hot air into the engine? No matter how efficient the inter cooler is, this can't be ideal surely?

Is the engine bay sealed like this for high speed aero reasons? I've not looked but is it feasible to open up a way into the upper wing vents to draw the engine heat out r would this bugger the handling up in some way?
I guess most of us won't drive too often at speeds to notice a small drop in aero performance at 150mph in real life

Added in 27 minutes 10 seconds:
Are the high intake temps causing 'knock' and the car retarding the ignition?

If it dials it back due to knock, does it automatically dial it the other way to release full power again, or doe the car stay at reduced power until the ECU is reset?

I run the car on Total Excellium if that matters?

[insigma]

dont you guys notice its the same when the engne is cold? try to rev it then its like glue... engine protection i think...

EDIT: not the same boost i ment.

I'm more shocked 3 FK2s snuck under the radar and landed on my doorstep you must of come in the back end of Corby off the 47 onto that long straight.

Quoted from Chris on TRO:

According to a reliable technical source, the FK2's engine cooling is marginal.

I noticed earlier in the week that my car felt as though its performance was noticieably down after sitting in traffic with ambient air temperature in the 30s, even when revving it out to the limiter.

Apparently the lack of additional cooling capacity is another reason why upping the engines HP through aftermarket means may not be as straightforward as just remapping the ECU.....

Chris.

I remember the 1st few wks from new I would see steam coming off the bonnet (enough for me to query it) I popped the bonnet and the heat was unbelievable , I could understand it if the car had been ragged.
Everything is so tightly packed under there & for a small turbo it really does kick off some heat & then add temps of 34 on top that, has anybody removed the heat/sound matting from under the bonnet yet, it might help a little

[Dragonfall]

We did sneak, drove like nuns all way as the cars were gleaming clean and didn't want to throw up dust and get em mucky en route!

Is the heat matting on the bonnet stopping the paint from blistering from the intense heat?

dont remove the heat /sound matting unless you want paint blisters on the bonnet its there for a reason and as you can see it doesnt cover the entire bonnet just around the turbo and engine cam

[Tas_Jeffers]

I always thought under bonnet insulation is for sound and not heat? I removed mine anyway, to release a bit more noise, only to see Honda cheap out on material, in comparison to the Fn2 insulation pad this fk2 one is like a few pieces of paper stuck together, no padding in between...

no, the inlet temperature does not create the knock, but if you have an inlet temperature of about 40 degrees, (has less oxygen) you lose around 10% power engine, so when we go around with an outside temperature above 30 degrees at the end of the games we have about 280hp

[dweezle]

Removing the insulation shouldn't cause problems, never had issues on my fn2 even with a fibreglass vented bonnet.
I did look on eBay for some sort of vent/scoops & then buy another bonnet to get customed made but there's nothing decent on there

[Helmigurt]

I also notice the drop in boost at very high outside temperatures! Max 1.2 over 30 degrees outside temp.

[joel]

is anyone else suffering boost drop off ,does anyone know the type and brand of turbo honda use IHI,garrett,HKS ??? (o please on the last one but i doubt it )

im from Singapore, where its 30-35 deg C all year round. and yes, after 2 hot laps at Sepang F1 circuit, the car gets crazily hot!!

the turbo that honda uses is a very versatile mitsubishi TD04 that has been used on so many cars over the years.



Added in 11 minutes 56 seconds:
i've ever encountered 138 deg C for oil temp on the factory gauge after a few hot laps in our very hot tropical climate here. there is some safety features built in and boost gets less.

i will be trying to remove the inside black plastic piece on the fenders to allow hot air to escape, and also remove the side fender garnishes. i believe that will aid with the hot air being stuck in the engine bay without a means of escape.

not sure if you noticed, but there are already 2 slits in the garnish made by Honda. i am guessing they want us to remove it so that hot air can escape if required.

[dweezle]

Good spot on the slots, it does look like they can easily be cut out, the slots seem pointless from factory

[sparkysp]

nice spot i think i might get the stanely out the weekend and do abit of slashing lol
any more tips like this joel and id be happy to heard them
also let us know how the temp go after the slot been removed ??

[jirka.sup]

My solution.... Bonnet vents will be next....

[joel]

remember to also open up the fender vents

the black part blocks off most of the heat you want to vent out from the engine bay.
a heater gun should help to detach the black portion easily.

[Coco-Pops]

Brilliant..!
