when do you need to upgrade your stock intercooler? is there a certian horsepower or amount of boost that it cant handle any more. also who makes the best one?

thanks

I would say Spearco, but they arent really necessary IMO unless you are running an all out max effort upgrade every little thing you can vehicle.


wht would you consider all out max effort upgrades?

i will have rods, pistons, cam, heads, injectors, twins, dual fuelers.... you get the point

These haven't been proven by any one yet to be a problem on a truck running The power there capable of moded or not. Some up grade because there available. I haven't seen anything yet proving the upgrade is neccessary to any margin. Any one else with proven hard data yet?

Thats the way I see it SD... people upgrade it cuz they want to say they spent over a grand on an intercooler.

Justin my build is similar if not more than yours (950-1000hp with twins) and Im going to run stock intercooler.

Anyone have any ideas on the PSI capabilities of stock intercooler?

The only reason id get a intercooler is if im towing 24/7. not for track runs. 1K for a cooler is a little steep IMO.

I have heard, no hard data personally, the stocker is taxed/stressed at 50 PSI. Try a search on this site maybe it'll pull up. I can't search well for whatever reason.

As for stock vs aftermarket IC's or water to air. Look at the pressure drops and efficiency between the stocker and some of the aftermarket coolers.

IIRC- stocker is 3-4%? Some of the aftermarket air to air are 1-2%, simply easier to push the air through it. The other part of the puzzle is how well they cool the air, this is a percentage based number as well.

When in doubt... use the coldest medium to cool the air and reduce as many bends as possible reducing friction heat, keeping air speed up. The more you bend, the bigger the pipe.

IMO- the IC is one of the small expensive parts on the list of improvements. PErhaps, if you use N2O, you could spray pre cooler to offset some spike? Guessing here.

Good luck with the build!!
