What kind of noise?

 

Oh okay... hmm. Thanks guys

 

Straight pipe

 

Dont do this put a SLP LoudMouth muffler on it gives a lil back pressure sounds like at least a V6 under the hood and its loud. So you get the best of both being "legal" and running straight pipes.

 

 

Where is that cowl intake getting the air from

 

The wiper cowl,theres drains for water so the airbox stays dry.

It intakes at the mesh on top of the cowl by the base of the windshield.

I've been using my cowl intake with the stock airbox for awhile and Its great because it serves as a true cold air intake.

 

Back to the back pressure debate lol. For those who think BP is necessary, quit getting the honeycomb cats and go back to the old pellet style. Thar be some back pressure!

 

Thanks. .... so who here has a good build it your self link.. I want this in my jeep now lol

 

Look at dukie564's build, Project Danger Cart. He does the stock air box cowl intake. It's cheap, easy, and doesn't use engine bay air like most "CAI's". I can't remember if he does a detailed write-up in his build, but he gives you a pretty good idea of how to do it. I did it too so you can PM me if you have any questions.

 

I believe in no back pressure which is why I recommend the SLP LoudMouth muffler. It gives very little back pressure and alows you to be "legal" on the street with your Jeep. Plus it sounds mean as hell.

 

Please forgive me, being a newb and all, but I simply have to correct this before someone takes it as truth. Absolutely no offense intended DieselD...

Engine displacement is a simple formula of: bore (squared) X stroke X # of cylinders X PII divided by 4 (0.7854).

Bore is the diameter of the cylinder and/or piston.
Stroke is the distance the piston travels in the cylinder from TDC to BDC
The rest are self explanatory.

An engine can gain displacement by affecting either the bore (being bored out to a larger diameter and installing larger pistons), the stroke (changing the distance the piston travels with a modified crankshaft) or both.

The term "stroker" refers only to the modification of the distance of travel of the piston, or the stroke. Make sense?

Sorry for post bombing a thread about CAI with this but I'd have hated myself if I had let it go.

 

OK. People still call them strokers. 4.7L Stroker, 383 Stroker...

I don't think the guy needed a science lesson when he didn't even know what I was referring to.

 

Technically yes, but the term is used generically here. On Jeep sites it you see "stroker" interpret it as "larger than factory displacement".

 

My humble apologies for my desire for correct information.
