this is a question for the know betters lol. Is a 3.5" intake or exhaust a worth wile investment? planning on building!!!

 

No... A 2.5" is plenty for 75% of people & 3" is plenty for the remaining 25%. A 3.5" inch intake would be worthless when you're feeding a ~3" throttle body / blower inlet.

 

^^^^ this. 2.5 supports up to 500 whp

 

i have a 3.5 intake and 3" exhaust haha 2.5 is restrictive if you arent on the stock m62

 

Never heard of a 3.5 intake before lol are you going tvs?

 

3.5 wont go over the axle without hitting everything in its way, so this thread is sort of pointless. sad to say.

not sure where you will find that or a shop to bend it.

 

Money can get you Nything.


However, both ideas would be worthless

 

3" intake would be best for a ls4 tb and tvs though. While ur at it port the head! 3" dp and maybe 2.5" exhaust lol. Make sum big boy power

 

thanks for the info! wasnt a useless thread if i got my answer!!! so its 3" in and out!!!lol

 

if you wish. 2.5 will work and is easier to work with for installation. Good luck with your project!

 

ignorance is bliss

wrong

 

so much fail in the thread

 

3.5 3.5 3.5 3.5!!!!!!
Im down to try
I made a short tube header with a 3.5" collector a while back.

 

My setup exactly does this mean I will have big boy power??

 

Under axle!




lol

 

or side exit

 

video video video!!!!!!!!

 

3" inch turbo intake, 3" turbo back exhaust (over axle Hahn) Making 420hp and still have lots of room to grow. 3.5 anything is pointless as Powell said. Even on a 900 hp corvette has dual 3 inch exhausts. After that kind of HP you would run an open header and drag the car. Again pointless but the guy has 5 posts so giving him a break.

 

Everyone seems to forget the area of a circle formula they learned back in high school.
Here is a simple area calculator
Area of a circle calculator
Try it out with 2, 2.5 & 3 and you will see why small increases in the diameter makes such a large difference in the amount of air you can move.

 

I have a 3.5 down pipe that exits the hood

 

I can't think of a 3.5 sounding anything less then completely awful on an lsj

 

I have 4 6in tubes directly of the head that is so awesome I had an oil painting of them done

 

Lmfao ahahaha

 

wouldnt that be an Up pipe.

Can I get copies to hang in my garage.

 

i like where this is going..
