So I pm bisi sale's rep about their nitrous cam! I was totally surprised by their response! I was trying to figure out how I am gonna port my y8 head to their spec to get the most out of the cam! I was also trying to figure out what their spring rate pressure were too so that I can have enough confident that the spring won't break at coil bind! I'm sure it can hold up but I'm a engine machinist and I need to know my tolerances...

but enough about bisi company I know they make great products but I wish I would of had a better response. So if anyone has bisi nitrous cam card and want to share please let me know, bc I have been thinking of a Big set up for testing!

 

Stop being vague. What was their response that you weren't satisfied and had to ask here?

Don't see how you cannot get a better response from one of their reps. maybe ask to speak to someone else.
