Any rise in compression will cause the motor to run hotter. It doesn't have anything to do with forced induction. The trick is to make sure that there is adequate cooling, and I would make the cooling adjustments that are needed to make sure my truck stays cool.

It is linked to forced induction because no piston/head combination can achieve the psi levels delivered by F/I. Even at just 8 psi you are orders of magnitude past what you could achieve N/A WRT the volume of fuel and air in the cylinder on the compression stroke.

You are right, you could purposely run very high compression in a N/A engine and it would be difficult to cool that engine as well but that is outside the scope of what folks on here were advising.

It's your money, spend it as you wish. You asked a question and we responded, we are only trying to help.

Nike said it best "Just do it", followed that slogan for most of my life in all aspects. I got my annual test results back last week all negative. Thanks Trojanman.

I'm gonna go the sc cams and headers route here soon. Gonna stick with the stock lower for now if it blows ill go forged.
if money was no option I would go 6.6l cp carrillo titanium rods and forged pistons 11:1. Head work 5 axis, port and o-ring Aeromotive eliminator fuel system. Twin turbos running around 30 psi run ms109 and shoot for 1500rwhp see what breaks and make it stronger. But that's just me

What you are missing here is that the intercooler that's shedding the heat is sitting in front of the radiator.
Less cooling for the engine.

The more heat from compression ratio in a n/a builds is a moot point, as you have to look at how much hp a blower motor is actually making.
The blower takes a very significant amount of power to turn. Thus the higher fuel demands, and heat produced with a setup for a given power level vs n/a.
The blower motor is making say 550 hp to produce an actual crankshaft 500hp.

I'm a huge fan of fi, built many turbo and supercharged cars.
But in the dirt, simpler is always better.
Add that to the heat, filtration and extra weight on the front end, and it's a no brainer if the truck is to be used really hard offroad...

Slap a killer chiller on there and I'm sure you'll be good. One definite disadvantage is the weight. Probably talking about adding 150 or so pounds to the front end between the blower and added cooling mods.

Have fun with the truck but I'm not sure why this thread was started since you have a clear idea of what you want to do and a simple search would have provided all the info you needed.

Some sience. As no one did it so far

A : compressing matter generates heat / expending matter soakes up heat
This means that a compresor/ sc or tc will increase the temprature of the gasses just by compressing them. The intercooling is there to decrease the gas temprature before entering the compressed state. Or decrease them onve compressed

This means just from the compression allone. The engine runs hotter
Better intercoling does not mean cooler engine


B : because the engine runs more air/fuel per cycle. The burn temprature within the engine will increase. This will increase the engine temp and the exhaustgas temp

To deal with this one must increase the cooling performance of the engine

Well if you have to SC one start with this---a Stage 3 then go to work adding a SC.... Bet the driveline won't last a weekend.

That is insane
1000horses in a raptor

No way in hell people can get that to the dirt
But what else would we need to make one of those reliable for more the 50.000 miles

And after 1.000 miles u need a rebuild?
