OH my my! Been contemplating doing this to my Rover w/M52. Very nice man!

So awesome. I love the sound and immediate power of a roots blower.

So, do you have a bracket template, or plans on selling the bracket?

[HighOnLife]

Dear god I want my S52 to make noises like that

Cool build!

Are you sticking to just 3psi?

That was the plan but a Buick m90 has a long snout and the intake is at the back I am not running a brake booster so I don't have a problem. I even shortened the intake for clearance.

Cool build!

After I get all the boost leaks out I am hoping to be at 5psi. my goal is around 8psi but I think my injector's might limit me.

So after getting the car running I couldn't get it to idle I had know clue what was up I played with the idle tune for hours finally got it to idle by maxing out the idle fueling. Drove the car about 20 miles then it started missing on cylinder 6 so I tore it down only to find this..

So I thought I jest burnt a valve oh well. I tore down the head only to find all of the exhaust valve's are bent.


While she is down make her perdy.
