youll need some copper tubing and an inline filter

 

makin 40 to 50 why do i need a drive pressure gauge

 

itll help you tune

 

what should i look for

 

you need to check your drive press, that 65mm exhaust wheel spools quick but chokes out up top.

When you read your drive press you compare it to your boost numbers. the best ratio is 1 psi drive to 1 psi of boost.

for example if you make 40 psi of boost you want your drive press to be 40 psi or less, and with that turbine wheel I bet its gonna be high.

 

I read somewhere that with an hx 35 when your making 35lbs drive pressure was over 60.

 

hum good idea where can i get one

 

its a boost gauge youll need copper tubing and a filter

 

If you want a better DV, get some .022's or .024's milled, more fuel, same heat as the 191's (the .022 might be a tad higher EGT wise then the 191's, 50* maybe). Put your AFC back in tune it and get rid of the 370's.
