Supercharged 4ac

Featured Replies

hi all. is it worth supercharging a 4ac. will it hurt my stock engine or how long will it last.

:dance: it will hurt your poor engine it wont be able to support the boost that the supercharger gives.

yea it will be fun tho, any idea how long it will last

it will probably last about 10 mins then crack something :P

Any engine can handle boost. The question is how much and how long. A 4AC has a 9:1 compression ratio (same as the 4AGZE) so it could handle a fair bit of boost say 6-9psi. Any boost must be accompanied by a well tuned engine management or the engine will self destruct. To say an engine can't be boosted is a misleading statement.

Give it a go, 4AC are a "dime a dozen" I have had fun gett N/A power out of mine and haver been getting good results. AS already said Compression is right on for a little boost. The Block will handle it OK, head and pistons might be another story, but you won't know until you try

Ok sorry i didnt know that he didnt care what happens to it. And the cost, time wouldnt be worth it. :P
