Thanks for the PM - keep me posted "IF" a used D1SC should become available.

If not we'll talk "NEW" - but for now I have to hunt for a used one

Thanks,Matt

I want more than my P1SC's capability - so it's out with the old and in with the new

Fella's let me know what you have laying around - the price has to be right -

'BUT' I am serious, I have set my mind to it and once I do that I do it!

It has to be Reverse Rotation for my C5's Set-Up ( 92-96 LT1/4, 97+ Up C5/6, 98-02 FBody Camaro, Firebird, 06-08 Charger, 06-09 Challenger)

Let me know!

Why wouldn't you be able to take the plate from the P1 and put it on an F1?

I can have my current P1SC turned into a D1SC for the price tag of $1600 from Procharger -

A total rip off IMO

(1) The F1 is much more than I want and need right now - there would be alot more involved in just slapping it on and throwing down some Boost on the Dyno - Other supporting mods would need to be considered and done in order to properly fuel the F1.

(2) I currently run a 1998 PCM with a 2 BAR Sd tune in it, I would need to at a minimum re-pin my PCM to a 1999 and up PCM to run 3 BAR - and I do not want to do that - Although the 2 BAR is only good till around 15 PSi the tables can be massaged in order to accomodate the 18+ PSI of Boost - But way too far to do a F1

You'd need to change more than just the PCM to bypass the 98's boost restrictions. You'll be limited to 14.7 pounds of boost.

(3) And although my 4L60E (Level V) is built, it is not such to handle what the F1 would supply in the way of RWTQ and RWHP, I would also want to upgrade my current 3200 stall as well -

"BUT" with the D1 I can, with my current set-up easily and safely gain an additional 80 - 100 RWHP and 80 - 100 RWTQ - then dial it back a tad for extra safety - which would put me at right around 18.5 - 19 PSI of Boost on my 2 BAR SD Tune

I donno man, I don't know if an extra 100hp/100tq is exactly going to be "easily" done with a D1, but it'll certainly be better than raising the boost on the P1. How are you figuring that much boost on a D1? At that PSI you're spinning the blower pretty hard, so hard that that setup becomes inefficient. When you're at the point your running 18+ PSI on a D1SC you should be upgrading to an F series blower

Believe me I would love to exercise a F1 but for my set-up and peramiters it would set me back way more then the $1600 for the P1 into a D1 or le$$ dollars for a used D1

So for now I will hunt for a used D1 or send in the P1 for the transformation


You do know that you can lower the boost on the F1 to not exceed a power level your trans and fuel couldn't handle right? Depending on your motor setup, and exactly HOW low you put the boost, it may be a little more inefficient but I've seen a LOT worse inefficient setups get by just fine (i.e. an F-1C on a stock LS1) I would honestly just look into an F-1 now
Thanks,Matt

But for now:
I know I can run a restrictor plate in the F1 and put the P1's tag on it too -

With the D1 it is okay to be at the max (so to speak) around 18 PSI - The VE tables and such can be fudged or tweaked, just like when a MAF tune is maxed out - "BUT" will be done maticulously (Man I hope I spelled that right ) to handle the extra Boost and although my motor is built to handle the Boost..... Arrrrgh! Scurrred I guess to a degree - I will check out the F1 and speak with my tuner - My HP Tuning is not nearly as advanced as he

The problem isn't anything PCM related at those boost levels. The problem is with the blower itself. The reason the D1SC is dangerous at those power levels is because the blower has to work very hard to spin the impeller at those RPMS and the impeller can actually heat up and expand and hit the casing and you've wasted nearly 2k and would likely upgrade to an F series blower like everyone else.

I will be running the 3.2" pulley I currently have @ 14.4 PSI on the P1, which will put me almost at the top of spinning the D1 but not over spinning it.

Obviously more peramiters will need to be changed when chamnging over to a later model (99+) PCM, I am familiar with the drill on that.

parameters? Do you mean things with the PCM itself or are you talking about the other sensors and other junk that needs to be replaced?

Great input I will consider the info on the F1 - shoot me back with some more info or arguments in favor - I have to drive to Los Angeles right now to go to work!

When I get there I will open my Laptop and see you response on anything I missed and anything new - please shoot away!
