Engine/Transmission (1998.5 - 2002) Should I be getting more boost with the PS64

[CHornsby]

Currently with the mods below:



Smarty: Level 9

TST PM3: Level 9

WOT = 38PSI



Should I be getting more?



I just ordered the "Mr Bob's" hoses yesterday, so they aren't on yet. I tightened all the hoses yesterday just to make sure and don't see any holes. Is 38PSI too low? Is it possible I just don't have the sticks to put it above 38???



Thanks

what is the wastegate set at?

Im running the sps66 and with just the comp drag i can throw 40-45 lb at 4000ft

I can get 43# with my stocker. I know its not smart and i dont do it all the time. i think it would do more but my clutch slipped.

I don't think that number is too far off. You could be opening the wastegate at that point also.

I'm getting 50 out of mine. I haven't touched the boost elbow since it came from I. I.

 

[CHornsby]

Well, originally I thought it was supposed to be set at 45, but 38 is all I get. Obviously, SOME error could be in the gauge, so 38 could actually be 40 I guess.



I'm just surprised that I'm not getting above 40. Guess I'll crank down the adjustable elbow a touch.

Adjust the elbow and see what you get... . The PS64 should be best somewhere around the 48 psi mark. Remember boost does not equal HP. It is a balnce of boost vs. backpressure and air charge density to make HP (along with fuel). The shop truck makes over 600 RWHP with only 45 psi boost.

Doug,



What the optimum max boost for a PS62 with a 12cm housing?



Thanks,

Hornsby,

Your boost does sound a little low.



Dont forget to come down to Franklin on May 27!

The one thing that everyone is forgetting... . if he doesn't have injectors... he may be running out of fuel!
