systemaxx

For those guys out there running holley systemaxx intakes. What size is the throttle body bore on them? Will they accept a 90mm?

I'm sure you can open one up to 90, but I don't think there would be much(if any) gain over a 75 in a boosted application. There are plenty of people making over 800 rwhp with 75's and boosted.

Mine is 75. Save $$$ and do the 75.

When I ran the Systemax I ran a 70mm and it was fine.
