Mya baby Posted August 3, 2020 Author Report Share Posted August 3, 2020 Mcdermott racing. Right now the set up i use it for is ice racing and it works well just locking for a smooth power curve. Going to power value Quote Link to comment Share on other sites More sharing options...
grantevans713 Posted August 6, 2020 Report Share Posted August 6, 2020 I'd be interested in the cylinders, pistons and intake, I have a coolhead, pipes and reeds already. Quote Link to comment Share on other sites More sharing options...

HOODWORKZ Posted October 21, 2020 Report Share Posted October 21, 2020 Hey I'm curious when did you have Harry from McDermott port your cylinders? I wasn't sure if he was still doing work and like him to work on my 421 cheetah pv. Thanks Quote Link to comment Share on other sites More sharing options...
