Single Turbo question? - Lateral-g Forums

Wilkinshc · #1 04-04-2006, 04:19 PM

What are the pros and cons to running a single turbo off one side of exhaust? Is it not possible? I am wondering about running a single turbo off one header because of space available, I want to run 6-8 lbs of boost on a 454 BBC. Any thoughts?

Thanks

i think you would have to run an exhaust crossover other than that you would be ok

Thanks for the reply but I was was wondering if it would work without the crossover pipe. I have very limited space (65 corvette).

Although not optimal I saw a 289 make about 600 rwhp with the turbo running off just one side and the other going to a muffler and tailpipe. I didn't think each side of the engine would even have the same a/f, but it worked very well.

camcojb,

Thanks for the info. I am wondering why you think the a/f ratio would be different? Is it because of back pressure on exhaust? Intake would have same boost.

I was wondering if half the exhaust could spin a big enough turbo without alot of turbo lag?

I appreciate help.

why not just do two smaller turbos?

I would think the exhaust pressure differences would do something to it, but if it does it's minor as he's been running it for quite a while this way.
