14psi on stock 87GT

289 · 08-22-2003, 12:10 PM

Hi

I'm thinking of buying a basically stock 87 GT with a 14psi procharger with a 3 core intercooler.

THis car has 24# injectors and a full exhaust other then that it is stock. Will a stock 87 5.0 run right with this setup or is this a good way to bust a piston or ripp this tranny a new one.

I don't want a fast car that does not go.
Thanks

Just run about 5-6#'s of boost and you will be O.K. You will need more fuel to run more boost, which means bigger pump(s) and injectors.

I would lower the boost, 14 sounds too high for 24pph injectors.As far as the tranny, I was making 360 hp and my t5 lasted 2 years. Thats speed shifting and never power shifting. I think procharger rates the 14 lb blower on a stock 5.0 at like 430 flywheel.

If you tear down the motor and o-ring the heads and get 30 or 42 # injectors and matching mas and a 255LPH fuel pump you should be OK.

You could complete the project in a weekend for less than a grand and have a fast @ss car.

DO IT!!!!

If your going to tear down the engine, add a main support system to. It'll help keep the block in one piece.

I'd say buy it and get bigger injectors and fuel pump and maybe a larger pully for the supercharger to down the pressure a little. I woulden't o-ring the heads so that if it does try to do something bad it will be a little more likely to blow a head gasket instead of blowing the engine. I woulden't think o-ringed heads arent necessary on a stock block.

Small block Ford heads are held in place with too few bolts. As a result, they are just begging to blow a head gasket. Add 14 pounds of boost, and it isn't "is it gonna blow a head gasket?", it's "when?".

Dark_5.0 · 08-28-2003, 10:51 AM

The stock block has nothing to do with weather or not you O-ring the heads.

As PKRWUD stated only 10 bolts hold down a 302 head. With boost you need all the help you can get.

IMO,

with 14 psi of boost I am not saying you won't blow a gasket. I am saying that if you o-ring the heads and with 14 psi there is a very little strength to spare with a stock block. if there is a slight bit of detonation or something goes a lil astray the stock block will prolly break something instead of blowing a gasket. Me I would rather replace a gasket than a block.
