I just installed the blox racing v3 intake manifold and I was wondering how much gain would have? The only other thing I've done to the motor was a 4-1 header with straight pipe to a cheap autozone muffler.

How much hp and tq would i gain with the intake mani and header?

How much would i gain with it being tuned?

Will I have more top end or bottom power?

 

simple answer? not much. a few hp. thats it.

unless, of course, your b18b is turbocharged... which I am assuming its not.

 

Probably a good assumption seeing as he has a 4-1 header.

Without tuning probably like 1-5 hp, with tuning on a dyno, maybe like 10-15.

 

lol oops
