Default What size restrictor

Hey all, what size restrictor is recommended for the 21-4c in a MP9 with a 9901 and a 41021 Pipe/header combo? Tried a search but came up empty. Thanks!

I used 7mm a couple races last season in my TKI2. It doesn't have the same top end compare to my OS speed so I switched it back. But I found the 21-4C work better in my STRR EVo with OS 2060 pipe.

The +4 will never have the top speed of an OS speed. 7mm is more than enough in buggy for me. Good balance between fuel consumption and power.

And my Plus4 kills the competition by the hundreds, and consumes OS motors with fireballs from its eyes, and bolts of lightning from its arse J/K

Hi all! Jumping ship next year from REDS to Nova. First engines i got advised to try were the virtus in truck and +4btt wc in the buggy. Ive got a few ordered, all factory tuned and sealed. Any advice on pipes and header combos? I understand im probably the 100000th person to ask something like this, sorry!
Any help or pointers would be greatly appreciated

Damn what a rant. Whatever happened to Fusion Motorsports? I found this post in a search always wondered what happened to them!
