Dual boost gauge range

[thunder550]

I am going to order one of the Hewitt dual needle boost gauges for my twin setup, trying to decide between the 0-80 psi and 0-100 psi range. I'll use one needle for total boost and one for drive pressure. 0-80 would be plenty for boost but I'm not sure what typical drive pressures are. Any help?

Lol...the internet filters at work won't let me create new threads but they will let me edit and do quick replies, so I have to create a new thread on my phone then come back on the computer and edit it.

What turbos does your twin kit consist of?

I have that gauge (100 psi) and at first I thought I should have got the 80 psi because you can't really see what the detailed drive pressure or boost is when down low. Then while trying some tune tweaking I appreciated the fact that I had the 100 psi gauge so I could see the drive pressure top out at 80 psi when I was at 50 psi boost. I retweaked the tune and got it down. If i only had the 80 psi gauge I would not know that it only went to 80 and thought it was pegged (so it could have been higher). Get the 100 just to monitor drive pressure while playing and tuning...

I did end up ordering the 100psi gauge. Thanks
