1 7/8in VS 2in HEADERS

Is there any power advantages with 2in headers VS 1 7/8? I have a L99 that would be supercharged with 2 in headers and torque converter. Suggestions Pros and Cons Please!

From what everbody has told me I believe that there is . Also search up the Jannetty Racing header test. The 2" was the best on the na motor as well. I am supercharged with a converter running the 1 3/4 and had no complaints at all but we are adding a blower cam and more boost ect so I went right to the 2".

Who the hell knows. Once things get going I'm adding this and that and only God knows where it ends. I think Jannetty wants to get a stock long block into the 9's. I just need to get the sack up to drive it. Thats ways faster than I have ever gone.

Thank you sir. Should be done the end of next week. And I would go with the 2" headers. That way you are set for anything you do, even a yr from now. Don't make the same mistake I did, but it did turn out allright.

Guys, With a supercharger you can run 1-7/8" headers to over 800RW with breaking a sweat. The 2" primary won't ramp up as fast. There's many determining factors that you should focus on before making a decision. Is this a street or race car? How much boost will I be running? Are you remaining with the stock engine size or are you building a stroker? What's max rpm range? What exhaust will you be running after the headers? And on and on...

Also keep in mind that we often up size our collectors on high boost applications. I highly recommend calling me and we'll discuss in detail what your plans are and I'll point you in the right direction. You can also PM me a number and I'll call you. Thanks.

Nick

From what I see the 2" headers are a good bet.You will never need a bigger set in the future.

We went 2" on our shop car in thought of future mods.Right now it's fairly stock and the 2" headers made a big improvement across the whole rev range.The car will have a Cam soon then a KB in the spring.Probly a stroker motor next year.The headers will stay.
