does anybody know how much of a horsepower increase im going to get with anew header? so far all i have is a cold air. also what will my timeslip look like.( i also have it gutted behind the front seats). thanks!

 

it depends on your car.. i know youre new but if you need big help just give all your car stuff year and model then ask away just to help ya these guys are great but you need to help them out....

 

yea sorry 95 civic ex coupe

 

Unfortunately, when Honda designed the 'Z6, they didnt' leave much on the table performance-wise. That means that bolt-ons (with the exception of forced induction) won't gain much power. Also, you must remember that nobody can tell you want kind of gain you will get; we can only give you accepted estimates of power gains; after all, each individual engine is different due to wear and tear. I'd say you should probably expect to gain around 5hp or so, but not much more. A full cat-back exhaust will net you an additional 5hp or so, andyour intake has probably already given you a few ponies (probably 3 or 4hp).

Also, 1320 times are really driver-dependant. All I can say is how much weight did you drop? The general racer's rule of thumb is that your 1/4 mile time will drop by 1/10 of a second for every 100lbs you lose. Also, the big thing is, do you have a 5-speed or auto transmission? Automatics are a lot slower than standards (a second or more on a 1320 run).

 

ive probably lost about 250 lbs. out of the back. also unfortunatley i am stuck with an automatic.

 

you are looking at max of 15 hp gain from header which is considerable for a 4 cylinder, a deeper sound and with that weight gone that is like driving without your fat friend in the car feeling the difference. common we all have had that big *** friend in the car and then you feel totally sluggish and whimpy. the moment he is out you feel a huge performance advantage

 

hey now! leave my fat *** friend out of it!

 

haha yes unfortunately i know the feeling...thanks for the input
