HJ gauge cluster (1 Viewer)

[blastr9]

I am planning on filling the radio hole in my HJ47's dash with three aftermarket gauges.

The three I am considering are pyrometer, water temp and oil pressure.

Are there any others I should consider?

What temp and pressure ranges for the gauges would be appropriate for a 2H with a turbo?

Cheers,

No boost gauge?

Pyro needs to go to 1800F, Water temp to ~280, and oil press to 100.

boost

GG,

Once the boost is (around 9 psi) the gauge will show that value unless something is messed up. Right?

I figured I would rather know the actual water temperature as opposed to if the boost was correct...

Am I missing something?


amaurer,

Thanks

so, I need the boost gauge to make sure that I am not exceeding the maximum boost (15?) at high revs?

and as a tool to obtain the optimum performance from my 2H?

Boost + fuel = High EGT's. I suppose if you set the boost to... say 9 pounds, and you know that to be correct, then you could just watch the pyrometer. If you want a bit more "get up and go" you will need to increase boost (maybe) definitely need to increase fuel. On my 2H, boost was set to 10 or 11 pounds, I had to add fuel. At first I didn't add fuel, EGT's were low, but so was the power. I gradually started adding fuel while keeping an eye on the pyro and tailpipe. You could start another thread about performance and turbo's, but do a search first, this subject has been beat to death.

Oh ya, Tapage would chime in saying "there is no such thing as maximum boost". Some on here experiment with 20+ pounds.
