im just trying to find a way to keep my turbo manifold not so hot... it gets to hot it broke the bolts off for my wastegate

 

Will this work?

 

it is the hardware section of home depot/lowes

 

ok u want proof look at a late 60's/early 70's muscle car cowl induction gm proved that it lowers intake temps by 30 degs back then

the hood spacers are nothing more than a form of cowl induction any hood and windshield meet point is a neg charge of air so lift the hood and u have a postive effect that pulls air down inside the engine cabin

and there are also a few R&D articles on diff sites look them up

 

so you want to lower the temperature of the exhaust manifold? you don't want to do that, a hotter exhaust manifold flows faster then a colder one and creates a better scavenging effect. just use thermal wrap on the manifold, buy better (grade A) bolts, take them to a shop and get them ceramic coated if you don't feel that's enough. use insulation on the intake tube, a spray bar on the intercooler and a thermal gasket on the intake manifold and you will lower the intake charge temperature.

and if you REALLY want to lower the intake temp then run water/methonal injection or a small amount of nitrous.

custom240sx is right in that everything will heat soak, especially the intake and the intercooler.

all i did to my car is replace the thermostat with a restrictor and straight wired my fan, i always turn it on at a red light. even on these insanely hot days my engine temp never goes past 1/4.

 

I have the back of my hood spaced upward about 3" with light weight hinge spacers plus a cold air box and cowl induction....to get cold air down the carb. The air filter is slightly pressurized. You can see it at the meets which I go to.

In your case, I would make some cooling fins for the intake, and put up a heat shield/cold air box, as well as pay attention to some of the suggestions you just read.-Bob

 

Yo K20 why do you have to be such a ball buster I put the wrong info and I owned up to it. And your post didn't cover crap from the thread either...
But any way I also have the hood lifted at the rear

 

Folks, the general principle is that since this is the internet,
if something offends you, either ignore it or don't read it.

Since other people read what a person says, no one needs to
make themselves look like a jerk. Take it to rants and raves.

If it doesn't meet the TR standards, the moderators
will take care of it. Thanks.-Bob

 

also u can relocate the turbo more towards the bumper and get a vent in the bumper so it'll have air cooling it from the out side. you don't have to leave the turbo right off the header but its a bit pricy since they don't make kits to relocate the turbo u'd have to get the piping bend it and weld flanges on it. I ran a mustang twin turbo and we put the turbos right behind the grill the incoming air helped cool it down. u can even put the turbo up be hind the bumper just watch you're ground clearance and don't have it right up close to the bumper or you will melt it.

 

I wrapped up my heads with 2layers of the wrap and I am so happy to say I can feel the differnce when I open the hood after a long drive..I even have a lot left I may wrap 2 tubes together then wrap the bottom of the header to protect the heat from the oil pan for longer engine life..so wrap does work well.
