im seriously leaning towarrd the idea of no intercooler, early 12v's ran withought them and the early powerstrokes ran withought them question is what will my egts be milage drop and what power drop throwing it straight into the manifold like the old 12vers

 

Why?

 

horrible idea

 

because it leaks and im the process of building my house right now so i dont realy have tome to pull it to fix it just want to bypass it tempoarily

 

How bad is the leak? Still might better than running without one

 

go to a radiator shop they can repair em they repaired mine for 30 bucks here locally and only took about 15 or 20 minutes. agreed above though no intercooler = bad idea

 

called the radiator shop wont attempt it cause its so thin. the leak is so bad ive been able to pin 50lb boost max now is 20lb at 60mph going up the hill to my house was always 10lb and now its 0 unless i peg it. i built a leak tester and all the air leaks out.

 

Find another radiator shop... Those things are not rocket science and they are repairable. In a pinch (pun intended) you can even use a pair of pliers and just pinch off a tube to seal them up.

 

or pick up a cheep used one

 

to answer the egt question:

Pre intercooler temperatures can be has high as 475°F. An intercooler with a good efficiency can drop this down to 150°F.

That means your egts can rise maximum by 325°, but only under full load.
You will not use full load while driving without an intercooler, won't you?
Because your intercooler temperature drop equals in egt drop.

I would use some epoxy metal and save some money until I could afford a good aftermarket replacement intercooler. Look at it as a chance to upgrade.
