Boost Check on Juice with Attitude!

[BIG BOB]

Today I installed a temperory 60# DiPricol boost gauge to compare it against the Attitude. Here are my results.



Under low boost contunious speed, Attitude read 4 to 5#'s, DiPricol read about 2 to 3#'s.



At 65 mph, Attitude read about 9#'s, DiPricol read about 6 to 7#'s.



WOT at 100+ boost levels were very comparible, max boost was between 39 & 40#s on both gauges.



The Attitude seems to respond slower than the DiPricol Mechanical gauge.



With these results, I will not be installing a permanent boost gauge, the Attitude is close enough for me.



Now to check the EGT's.

Your attitude sounds more accurate to me @ 65 mph, and are in line with my Westach guages. Of course this will largely depend on the atmospheric conditions present when your 2 different guages, from 2 different companies, in 2 different climates were zeroed or calibrated.

Keep in mind that I have a B1-2-04 Turbo, which is quite a bit different than stock.



I was talking with Piers at Dynomania and he said that a turbo is matched to the engine when cruising between 60 & 70 mph on flat ground, your boost level should be about the same as the first number of your EGT's. Example if I'm driving 70 and my EGT's are at 700, then my boost should be around 7#'s.



Now, having said that, my boost numbers on the Attitude are very close to what Piers had told me. It was just in this instance in check boost levels that I checked the difference between the two.



Boost at 65 mph will react very quickly, the slightest encline will show in the boost immediately.

Just remember that the Juice/Attitude can not show boost over what the MAP provides the ECM, about 40psi is the limit. The same thing with the TST boost display. I have seen Attitude show 38psi and Autometer show 48psi. So with just the Attitude for boost readings you will not know when you go over 40psi or so.

Where is the map sensor?

Now to check the EGT's.

Please, please, please tell me(us) what you find. I've got an autometer EGT gauge that I think may be on the fritz. At least I hope it is. I'll save my scenario for your next thread.

Cool. What is the sensor mounted to the airbox outlet?

INLET AIR TEMPERATURE SENSOR/PRESSURE SENSOR



DESCRIPTION

The combination, dual function Inlet Air Temperature/

Pressure Sensor is located on the air cleaner (filter) cover.



OPERATION

The Inlet Air Temperature/Pressure Sensor is a

combination dual-function sensor. The sensor element

extends into the intake air stream at the top of the

air filter housing. Ambient air temperature as well as

barometric pressure is monitored by this sensor. The

Engine Control Module (ECM) monitors signals from

this sensor.
