i'm putting another new belt on my car tomorrow and i'm almost ready for the new engine to go in. sooooo i was thinking, why not bypass the IC and run the boost from the blower right to the TB for a while. i'd be at about 14 psi and i can richen up my tune a LOT. are there any downsides to possible blowing my engine? all i'm using off the old engine is the heads.
think i should try it?

i RARELY drive the car. maybe once every 2-3 weeks. the new engine should be ready in 3-4 months.
maybe it will last that long.

if it does go, do you think it'll trash the heads?

I'd say no..... but that's just me.

Why are you doing this again? Why not just up the boost? I would think a few more pounds through the intercooler would be safer than no intercooler at all.

Running lean makes the engine really hot, which causes detonation. Running high boost without an intercooler makes the engine really hot, which causes detonation. Am I right?

Why bother? If you don't blow the engine you might be able to get some $ for the shortblock if it is in good condition

I supose you could do that if you'd like.....but your ACT sensor is probably going to sense the temperature increase and just retard the timing at the top end to compensate and you're not going to see as much power as you may think......but you'll still make plenty of heat and in all likelyhood still probably **** the engine.......so I guess two out of three ain't bad!

Pointless IMO. You could still have some flakey situation happen that might damage your valves, or damage the head itself. Too much of a risk for no real gain.

You wont gain anything by bypassing the IC. Just be WAY harder on your engine, and you will probably blow it up. Its definatly possable that your heads will be damaged.

So when the new engine goes in, how much boost you going to send through her?

i have 29K on my engine, so it may be worth a little. i guess i'll just run the IC with it.

i plan on running a 2.9 blower pulley and a 10% OD crank pulley. that should be around 17 lbs.

If it's in good shape, why ruin it. There are dozens of '96-'98 Mustang owners and '94-'97 MN12 owners crying for a good used PI engine every day. If you've got money to burn, then have at it. Otherwise, you're looking at an easy $1,500 in your pocket if you sell it. Doesn't make sense to abuse it.

You're sounding an awful lot like that kid that throws the empty pain can into the fire place because he wants to hear the bang. He knows its wrong and that he shouldn't do it, but he just can't help himself.
