How Much HP Are These Mods Good For..?

[solaris=amazing]

Hey guys, i got a completely stock 4.6 V8 95 tbird.

I'm gonna take out the air silencer, and then make a custom intake. It's gonna be basically a long elbow pipe in place of the stock air filter housing, this will be run down to the fender wall. The filter i'm gonna use is a universal cone filter from K&N. I'm gonna fabricate a custom shield to scoop up alot of air towards the filter (no more warm engine air) yet keeping out rocks and stuff. I'm gonna keep the stock intake housing on the engine cause i really don't think a pipe would be any more beneficial in that area, being that the intake housing is very wide.

I'm gonna keep the stock mass air flow sensor and throttle body also.

The next thing is chopped off mufflers, those will go bye bye, and be replaced with chrome straightpipe the same size as the exhaust pipes.

PS, i'm keeping all the cats, just taking out the mufflers to get a more aggresive sound.. It sounds good, already heard it on another bird. The engine is 205BHP, and 265 lb-ft torque.. I'm guessing maybe 10 more RWHP...?

Good guess. I would say the intake would offer very little, but the open exhaust will help some.

i'm gonna say you'll gain 4-5 hp at the top end and gain no torque, possibly even lose some low end torque.
