HiTech built my pump and supplied my headers. They're the jacketed stainless steel with the so-called anti reversion tubes on the website, maybe a 14" collector. Scroll down from this link.

I wasn't sure what to expect from a quality standpoint but 5 years, 1100 horse, and they're run really hard and they still look and run like new. No leaks or cracks and no reversion issues.

Thanks a bunch for that info. I just checked out their page and I think I found my new headers.

Flusher,
Thank you for taking the time to write out such a detailed response. I have a better idea of what i am up against now.
Thanks again.

Do supercharged engines suffer equally from exhaust reversion like an NA engine with a larger overlapping camshaft? Does supercharging have a mitigating effect on reversion? I ask because i am currently working on a supercharged/intercooled combination for a 21ft Placecraft and i am considering running a crane roller camshaft that i have on the shelf. I intend to run lightning jacketed tubular headers with a long collector and water/exhaust mixing as far from the exhaust port as possible (with some consideration to the noise levels). The proposed camshaft has the following specs: 260/270 I/E duration, 110 lobe center, .663/.638 I/E lift. I ran this camshaft and solid roller lifters in a previous blown engine (mild setup) with success. If the proposed camshaft makes sense for my new project I would want to run hydraulic rollers this time.

Please let me know what you think.
Thanks in advance. CK

A quick and easy test to help narrow in on the issue before you tear it down is to put some wd40 into the low compression cyclinder and see if the compression numbers temporarily jump up. If they do, its usually a sign of worn rings, If the compression numbers remain low than you can more than likely assume its a valve sealing issue and go from there.

If you have an open in a plug wire or a cracked spark plug you would be having a miss all the time. If your only having this in the higher rpm range, it could be a possibility that your valve springs are getting weak or even have a broken one, check them all very closely, maybe it’s time to change them, springs only have so long of a life, heat and duty cycles will cause the coils to weaken.

Thanks for all of the info. I never thought about a sea/sand strainer. Good idea. I assume any quality strainer will do the job. Thanks again.
