() Date: March 13, 2023 09:35PM Jon Brakke had big reverse rotation cams when he was running the Hewland. Probably not a TB-30 but maybe a big Howards or something. It's been a long time but I know the Hewland did not go with the Corvair. Jim Brandberg Isanti, MN CorvairRepair.com ![]() Re: Needle in haystack cam needed OTTO TB 30 Rev Rotation cam Posted by:

() Date: March 14, 2023 07:23AM Thanks Jim, Thanks for the reply. Yup , I now remember that scenario. This need is specifically for a Turbo reverse rotation 3.0L drag race engine. Pushing 15-20 PSI of boost. I have a TB20, but wish to go bigger. The search continues !!

() Date: March 14, 2023 08:59AM Bob, Make your own! Make a sleeve bushing to press over the non drive end for a press fit and bearing change then turn down the drive bearing to the smaller dimension. Instant reverse rotation cam. I have one here just like that from Otto Parts!

() Date: March 14, 2023 09:29AM Hi Ken, Yes I can do that, easily. To a OT30 I have hear. But the OT30 has a different exhaust lobe than the TB 30. So I really need a TB30 to reverse it RR configuration. In the interest of time, I am trying to press "the Easy Button ". If it doesn't work, I will seek a TB30. And change it.

() Date: March 14, 2023 11:40AM In my little turbo knowledge if I was drag Racing , I would turn up the boost (Billy Bruce 30lbs) with a tight lobe center cam and blow the excess out the exhaust. Billy has no boost control and distributor timing is locked at 32degrees !! 1964 Bill Thomas Monza Replica Racer 1964 Spyder Street Car 1998 Honda Prelude Dirt track car 1967 Crown V8 under construction Mike Levine Cumming Georgia North of Atlanta Re: Needle in haystack cam needed OTTO TB 30 Rev Rotation cam Posted by:

() Date: March 14, 2023 12:58PM 30 PSI will sure get the job done. Gonna start lower 15 psi and add boost as needed. Starting with F/B combo, then going to aftermarket E flow turbo. Probably need some kind of exhaust pressure boost controller. Bob C aka Dryenko Dobson, NC 27017 Re: Needle in haystack cam needed OTTO TB 30 Rev Rotation cam Posted by:
