I'm just about to fit a che manifold and am going to run without the heat shields (I think it will look better!). Then I'm going to replace the bit under the engine cover with some sort of mesh (Ripspeed or whatever) All of this is covered well by previous posts but I will also be using an ali baggage rack later in the year to go to Germany (mainly high speed autobahn stuff but will not be able to avoid town traffic). I'm a bit worried about heat build up on the luggage (suitcase!) given the modification.
Has anyone got experience of anything similar?
Thanks
did it with a PPE header (no heatshield), no dip tray and a luggage rack : suitcase was hot, but cooled enough by the flowing air :-) :-) :-)
don't put make up or camenbert in there, thought s:-D :-D s:-D
thanks dieamond
I'll go for it
Better bring back red rather than white though s:P :P s:P
The heat shield is there to keep heat in the manifold; Hot exhaust gasses flow faster. It will also protect the finish some. I had the leather straps that were optional with the Classic Carrier get so hot (with heat shield and TRD header) that it "cooked" the leather (lost its softness, got thinner, like beef jerky).

I would think twice about not fitting the heat shields, stainless does seem to run a lot hotter, especially in this weather. the heat haze coming out of the engine cover is pretty amazing s:shock: :shock: s:shock:

get turbo then, it completely distorts when it gets real hot s:? :? s:?
remember the golden rule, keep the engine cool and the performance can be played with, let it get hot and you only dent the performance
So Whats the best way to keep it Cool?
Heat Wrap, Ceramic Coating or Fan in Bonnet Lid like TTE Turbo?

all the above, plus dont forget your trying to cool the engine as well, that means removing the heat from inside as well as out. So upgraded oil cooler, radiators etc etc, use your imagination, thats the beauty of modification

Yep that's why I'm sticking with a conventional design, I don't fancy the idea of a molten plastic design back end s:shock: :shock: s:shock:
with the heatshield for the exhaust in its fine, the others can be removed if you really want, but remember Mr.T put them there for a reason
If you look at the design of the TRD stainless manifold - which the Che manifold is a copy of, it has the fitting for the heat shields which means they reccommend the re-fitting of them - you would think s:? :? s:? Plus if they can't see it then the warranty is not such a problem s:shock: :shock: s:shock:

I'd ceramic coat it
Does anyone know much about ceramic coating (Yes Ive tried the search s:) :) s:) ) Ive seen an add in PPC for a ceramic paint. Is this normal? Do you just paint it or do you have to treat it to high temps

They have a facility in France, so I bet it's the same in UK :-) :-) :-)
Im searching google but no luck so far in Ireland
Ah the un-luck of the Irish s:lol: :lol: s:lol:
theres this lot that coated my kit

Whilst I think that Lee's old car looked blinkin' awful in the engine bay (:wink:), all that exhaust wrap he used everywhere made an incredible difference to the underbonnet temps at Anglesea, so much so that I wouldn't hesitate in recommending doing something like that if you're worried about it getting a bit warm under there.

Stu has posted the Camcoat link above, but you
can have a go yourself if you want. The paint is available from Demon Tweeks (and others) in black, dark blue or chrome (here). (http://www.demon-tweeks.co.uk/products/ProductDetail.asp?cls=MSPORT&pcode=NIM1706) Note that Camcoat use a build-up of several different coats in their process though.
Yes, you'll need access to an oven. Go get friendly with your local Pizza place s:wink: :wink: s:wink:
Do you just do the Header or is it better to do the whole system, header cat and exhaust?
Quote from: "kj"Do you just do the Header or is it better to do the whole system, header cat and exhaust?
whole system, right down to the exhaust tips
to give you an idea of how well this stuff works i can touch the exhaust box after a 10mile drive, the header however is way too hot to touch even with a triple coat of the stuff
I might give the exhaust wrap a try, just to cool things down a bit, I am sure I can do a nice tidy job of it so as not to upset Dan s:wink: :wink: s:wink:
use the silicon spray to seal it after or it will hold moisture and promote rot
If you are driving the car daily, is it likely to be damp for long enough, given the temperatures we are talking about
Paint first then wrap - some people say this helps prevent the rot. I stress the helps - I've wrapped steel mini manifolds after painting them and they still rusted.
Its already painted, but I might give it another coat first. What are the consequences to the tune, if any, with keeping the heat in the exhaust for longer guys
no issues with the tune, buut if you seal it with teh silicone pray you get the best of both worlds
Quote from: "turbo steve"Its already painted, but I might give it another coat first. What are the consequences to the tune, if any, with keeping the heat in the exhaust for longer guys
should be fine on that score, the main issue is when the heat enters the engine bay and causes the the air inlet temps to rise, the paint should keep that in and throw it overboard
thanks guys s:) :) s:)
Ok, so ive dug this one up from the depths.
Recently swapped the manifolds over, and removed the heatshields in the process. due to all the rusty bolts that attach it, i thought i would replace them some time in the future.
I have a question.
What is the purpose of the Heatshield around the manifold. Is it to keep the heat in as suggested on page 1 of this thread, or is it there to protect the other engine components nearby, i.e. melting the O2 sensor wires etc.
Any guidance would be gratefully received.

Let's put it this way:
I don't have one.
Nothing has caught fire yet.
s;) ;) s;)
The stock manifold is fugly though, especially with no drip tray above it to stop it collecting water s:oops: :oops: s:oops:
basics if i am right are that ehaust gases move quicker the hotter they are. the hotter it gets the quicker they move and the move you shift out your rear.
the more you can shift the more you can take in, and there for the more fuel you use, and combined with the air the more power.
this is true to an extent, but the role that it plays on the mr2 is marginal. i think we would be talking 0. something of a bhp. if it was an f1 car, then it would be different.
please correct or adjust where neccessary if i am off the mark! s:wink: :wink: s:wink:
I am getting some heat wrap to go on my Che manifold because i am removing the heat shields (extra weight!), but where can i get the silicon spray from to go over it?
