What to measure with twins?

[thunder550]

Going to add a second gauge pod here in the near future to monitor lift pump pressure, will have 1 or 2 extra spots for gauges. Currently also have boost, egt, and rail pressure.

What's important to measure on a twin setup? High and low pressure boost, high and low drive pressure? Are these more for DIY tuning or is it good to keep an eye on them if I have tunes from one of the popular tuners? How about egt?

Primary boost or oil temp

I plan to measure engine oil temp at first then probably drive pressure for tuning then back to oil temp.

being you will probably never tow with that rig, id run this

overall boost, primary boost, egt, lift pump pressure, and drive pressure (switch this out with something else if you choose after tuning is dialed in).

i only want to monitor what i cant in EFI Live.

If you want to dial it all in you will need both boost gauges and drive pressure gauge. Without all three you cannot know if it is all the best it can be. You could dial in boost b it not know if the overall setup is right.

Thanks guys. I think I'll do the following:
1. Dual boost gauge for boost pressure
2. Dual boost gauge for drive pressure
3. EGT
4. Lift pump pressure
5. Rail pressure (since I already have it)

I'll run 1-3 on the A pillar, then get an overhead mount for 4 and 5.

you only need one drive pressure gauge.

Ok, that makes things a little bit easier.

lol just a little
