installing a turbo with small exhaust

[JAYHAWK 1962]

anyone knows what happens when you install a turbo on an engine and leave the smaller diameter exhaust on the vehicle? would there be a back pressure problem? engine blows up stacks go flying? any ideas? thanks as always

Probably not a problem. When installing an exhaust brake butterfly valve, it should be about 20-30 inches down stream for back pressure considerations, a smaller dia exhaust shouldn't come close to that in interfering with the turbo.

The problem I see is the turbo mounts up to the exhaust differently. Wish I saw this yesterday morning, could have gotten pics for you.

The Exaust gas temps would probally get too high. The turbine blades would then deform.

Why on EARTH is this in the Military Radios and Other Electronics section?

Same reason a lot of the posts recently, have been in the wrong forums. People don't pay attention !

Please make an attempt to reread and look over your posts. Make spelling corrections and use Capitalization and punctuation(not only polite, but ITS THE RULES!)

It is perfectly acceptable to see new people make simple mistakes, but you guys that have been around a while really need to try a bit harder to keep these forums neat, clean and useful!

Thank you for your time....

I understand about putting stuff in the right section. but i think telling people that they must ( its the rules ) have correct spelling and grammer is a little far fetched.

I don't think it's too much to ask people to use correct spelling and grammar. It's easier to read when an effort has been made to be correct. I skip over posts with bad grammar, run-on sentences, and consistantly mis-spelled words.

Small pipe wont allow your turbo to spool up as fast as larger pipe. Turbos rely on pressure differences in the exhaust system. A turbo creates backressure between the engine and the exhaust inlet of the turbo, without this the compressor will not spin. The greater the pressure difference between the inlet of the exhaust side and outlet of the exhaust side of the turbo allows the turbo to spin up to speed faster. The smaller the outlet pipe of a turbo, the more backpressure on the exhaust outlet, which equals less total pressure difference across the exhaust side, which equals slower the spool time and lower outputs.

I'm not perfect, never claimed to be, and far from it. However, I do have pride in my language skills. When posting on these forums, you are presenting an image to people, since most of us do not know each other personally. My suggestion to individuals that post is just do your best, and don't be lazy with communication skills. Just my 2 cents.

I never said I have an issue with grammar and punctuation. i just think its a stupid rule.
