jevansio Posted July 21, 2008 Share Posted July 21, 2008 Bear with me here, about a week ago while diagnosing a blowing noise from my manifold, I was poking around & the heatwrap started falling off in chunks. I ended up removing it all. Soon after I split a Samco hose, the one that connects the compressor to the FMIC pipes (the hose now closest to the exposed manifold). I put it down to wear & tear at the time but knowing I was getting a new FMIC shortly I thought I'd use the opportunity to put hoses on anyway. So weekend just goneI put the new intercooler on & a new Samco hose onto the compressor, took it out for a quick run, 1st run it held fine, 2nd run it wouldn't hold as much boost I've had a good look down where the Samco hose is & this one is split, the manifold is getting that hot & the hose is cm's away from the manifold that it's just disintegrating after 1 or 2 runs. My question is, is it OK to wrap the samco (rather than the manifold) to protect it? This would be a temporary measure as I'm in TOTB this weekend & just want the car running for then. Or would you say that I'm being silly bodging something "just" so I can run. (I wouldn't normally entertain such an idea, but I'm really looking forward to this weekend). Also is a blowing manifold a serious problem? Can any damage come from it? Quote Link to comment Share on other sites More sharing options...

Can any damage come from it? apart from searing heated fumes catching something alight, or giving you carbon monoxide poisoning it should be fine jay:blink: i used mine with a blown manifold gasket though but i live dangerous;) Quote Link to comment Share on other sites More sharing options...
Alex Posted July 21, 2008 Share Posted July 21, 2008 Wrap the manifold again. It's better for performance through efficiency. Quote Link to comment Share on other sites More sharing options...
uk-rich Posted July 21, 2008 Share Posted July 21, 2008 i made a small heat shield that sits in between the manifold and the turbo silicon hose Quote Link to comment Share on other sites More sharing options...

Wrap the manifold again. It's better for performance through efficiency. I did think of that (obviously ), but it is far beyond my expertise, I'll have to see if I can get it booked into Motoscope before the weekend Quote Link to comment Share on other sites More sharing options...

bolarbag Posted July 21, 2008 Share Posted July 21, 2008 Wrap the manifold again. It's better for performance through efficiency. What is the reasoning behind this other than spool, not knocking it, genuinely curious Quote Link to comment Share on other sites More sharing options...

jevansio Posted July 21, 2008 Author Share Posted July 21, 2008 It could burn the mating face on the head. And this would render the head useless? How long does this burn take? Quote Link to comment Share on other sites More sharing options...
suprasurrey Posted July 21, 2008 Share Posted July 21, 2008 What is the reasoning behind this other than spool, not knocking it, genuinely curious I think the reasoning is that keeping the engine bay as cool as possible increases the air density, and therefore increases the amount of fuel that can be added to it. Cold air will also expand more than hot air, thus applying more force to drive each piston down. This is why turbo charged engines seem more powerful on cold winters mornings.

Chris Wilson Posted July 21, 2008 Share Posted July 21, 2008 It's fine to wrap the Samco hose, but use reflective wrap to keep radiated heat OFF an item, and thermal blanket wrap to keep heat WITHIN an item. The hose shouldn't BE within cm/s of a manifold runner in the first place though.... Quote Link to comment Share on other sites More sharing options...

Thanks for the tip on the reflective stuff Chris, I'm ringing MS so hopefully I can get a pro to sort it rather than my half arsed attempts Quote Link to comment Share on other sites More sharing options...

That can be done with a heatshield Out of curiousity Jav, do you have the IC pipe going through the fender or is it down and under the chassis leg?

jevansio Posted July 22, 2008 Author Share Posted July 22, 2008 I've got it going down & under the chassis leg bolarbog The car is now booked into MS so fingers crossed it'll be fixed by the weekend, Envy are supplying a new exhaust manifold gasket ASAP (cheers guys) so it's in the lap of the Gods now. MS are going to re-wrap the manifold & either fashion a heat shield or wrap the IC pipe in reflective material. Quote Link to comment Share on other sites More sharing options...
bolarbag Posted July 22, 2008 Share Posted July 22, 2008 Fook:) I have a WG trying to poke its shiny head through very close to one of these couplers, this exact coupler, heat shield needed me thinks Quote Link to comment Share on other sites More sharing options...
