You wouldn't happen to have a flow meter would you, fuel into IP and fuel returned from IP for true mpg would be handy.

IMO no need to monitor fuel solenoid driver for temps, I did that for test in "Points to Ponder Thread" was a crude test that told me all I needed to know, also at Pensdacola Fuel we did some tests with IR gun of IP on test bench under a minute free hanging off IP >250F mounted on test stand & on IP we saw 180 or so IIRC been a while since looking at that for me to remember, but it was sufficiently hot enough to know it's too hot and keep it out of the engine bay. Real world function has confirmed that as well, 3x fail under hood in 2 years, 0x fail out of engine bay in 5 years with the heath remote.Put a thermocouple on the PMD
....hmmm sounding better and better. Hey Dennis, how's my turbo coming along? ..just yanking yer chain.
This seems to lend more credence to the idea of an optimum intake temperature; 150*F as I recall someone saying. I'm thinking it would be interesting to set up a way to control and adjust the intake temp to see approximately where that ideal temperature is. Gadget nut that I am, I've got an 8 channel thermocouple input data recorder that I'm looking at installing on my rig before I get the ATT on it. Just to get a good before and after set of numbers, for entertainment value of course. I'm thinking of the following inputs:
EGT pre turbo
EGT post turbo
IAT pre turbo (ambient or Outside Air Temp (OAT))
IAT post turbo
..anything else you guys want to see? Four channels left!

iv spent the last hour or so skimming this whole thread and i still dont have all the info to try and understnd this TD or Slim could you write up an overview of what the advantages of this turbo are? like difference in what range it spools at, any difference in MPG, Max boost, differce in turbo wistle (every one loves that sound)
I have a gm-3 on my 93 and it dosent spool till btwn 1600 and 2000 rpm. crusing at 55 doing around 2500 it makes 2-3pounds would really like to
im sure all that was in this thread but unless its all un one place i just cant understand it
Thanks

im confused what keeps it from boosting to much
sorry didnt mean to try and get this thread off track was just looking for some comparison numbers

The turbo is more closely matched to our engine, you will see approximately 2 to three psi boost cruising and up to 18 psi under load and WOT, depending on the amount of fuel you are capable of getting to your engine. The turbo in my opinion is just flat better for our engine.
Hasn't on mine, but FWIW I rarely if ever see boost over 10psi unless towing something, but to get maximum output from the turbo you will need a program that supplies the extra fuel to fully drive the turbo to max capability.Would 18psi with a stock compression engine cause problems with lifting a head if sustaining such boost? I assume not, but why?
