GSXR header lengths

[Christopher Crowe]

Does anyone have (and would be willing to part with) their exhaust header tube length data? We got a funky one and the primary tube lengths are suspect (among other things). Also, are people developing more useful power with a two-into-one then the two-into-four configuration or just a straight four-into-one?

Another question. Is the stock Suzuki Ti header an efficient performer -- or was it overly compromised to fit the bike space limitations?

Thanks for anything you can give us in this area ---

You need 3/4" primaries that are 59" long fed into a Quad-Z collector with 1" secondary.

Ordered the stuff, am building away. You should see the thing! Remember the "Bundle of Snakes" on the '65 Lotus-Ford Indy car? This looks like at least a ton a snakes. And man, does that last 1" collector ever get red. RED!

That header design link is fantastic!

Do anti reversionary systems work on these engines?

A lot of bike guys get into these things for their engines. It must work. But I don't fully understand the damned things.

I noticed a lot of the header design tech is geared towards better mid-range power. With our bike engined cars aren't we mostly interested in the upper to peak power rpm range since we have plenty of gears to select from to stay near peak rpm?

Another good source for Header design info is Burns Stainless. They are located in Costa Mesa CA. WWW.burbstainlss.com

On their Home page is a Header design link. Fill it in and e-mail it to them and they will E-mail you back with specific design info.

In what rev range do find your GSXR running for most of a racing lap?

Thanks,

Yes, but my mom let me stay up late.
