  3. Supercharger boost vs. HP vs. efficiency

    in Forced Induction and Nitrous

    Posted

    Have this posted on PT, but not getting much input. So I thought I would try the experts here.

     

    This is a question about the efficiency of a P1SC versus a D1SC. I know a S/C takes HP to make HP, and I believe the D1 is more efficient than a P1. I think the P1 is a radial design and the D1 is a spiral design, so does the D1 make more power at the same given boost level as a P1?

     

    So my theory is that with a D1 at 12 psi would yield more HP than a P1 at 12 psi. Is my thinking correct? If so, does the additional power come from the more efficient design, or it just takes less power to turn the D1? Or both?

     

    I am trying to weigh the pro's & con's of upgrading my P1 to a D1, and was thinking out loud about the performance increase, if any, of just making that change alone (with any tuning adjustments).

     

    Thanks in advance guys,

    tahst about what im making with the 3.1 im at 11. so with the 3.2 dont you think that a bit much for a stock lq9 to handle jmo but im planning on running somewhere between 12-15 on a forged bottom . what prochrger are you running? whats the max boost for its model on the 6.0?

     

    It is a P1SC. I am not going to put it on until I get it retuned. I want more, but don't want to instantly grenade it either. I might never put it on after the retune!!

    Just a few more weeks & I'll know for sure.

    lol, i want to try it first and see where im at. how much did you guys pay for the pullies??

    About 8000 miles on mine so far, no problems.

     

    I called RR to make me a custom 3.2, he said would be about $125-150.

     

    I have a 3.6 RR right now and hit 9 on a really cold day if I am lucky. What are you running for boost with a 3.2"?

     

    No dust around the pulley? What about belt size you are using with that 3.2"

    I am still running a 3.4 for now. I just upgraded to 60lb injectors, so the 3.2 will go on soon.

    I see about 11-12 psi with the 3.4 now. I do get some dusting, but it isn't bad at all. I run a 110.5 Gatorback.

    contact a custom cam maker such as futral, and dont waste your money on a hand held, get a dyno tune or a mail order tune .

    :withstupid:

    You are wasting your time and money with the handhelds.

     

     

    Even with daiblo u are! I thought it was just as good! I guess I was wrong my bad. I feel like and idoit now I just bought one! :dupe:

    Live and learn.

     

    Almost all of us have been burned by some type of mod. Mine was wasting money trying to make an exhaust. Ended up with Corsa. Would have saved a couple hundred bucks if I would have just bought it in the first place!!
