just called procharger about the D1x and they said it should flow about 7-8% more than a D1sc mostly in the upper rpm without sacrificing any mid/low end and he thought most users would see maybe 70hp more. They will be keeping the D1SC in their lineup and this will be a new addition as a middleground between D1 and F1a. He said they won't have exact pricing until February and details but that internally they are expecting it will be ~$300ish more than a D1SC if bought outright. He said the impeller is different and the volute is upgraded, he did not have any details on gearbox changes but he hadn't heard of that being much different.

given the amount of changes to the D1x vs. a D1SC though I can't see it being cheap to upgrade. for a stock D1sc impeller procharger charges something like $1k but so with a new volute I'd assume at least $1500 just in parts and then some labor and that's without changing any bearings or seals. I'd guess it would end up being at least $2500 for an upgrade if it's even possible, which doesn't really make sense when that is almost what an entirely brand new blower can be bought for and you can then sell your old one.


also for the extra 70hp I'm not sure this D1X really makes sense as an upgrade. I've confirmed with procharger the f194a is much more modern design in multiple ways and should have the lowest parastic hp used to spin the blower per unit of hp of any of the street blowers and guys have made 1200whp with those, and it's only like $650 more than a D1SC or whatever, so with that in mind I can't see paying $300 more for the D1x to gain 70hp when you could pay just a little more and get a much gnarlier blower. if starting from scratch then d1x probably a nice upgrade over buying a new d1sc if you want to make 900+whp but if we already have a D1sc it looks at least to me like some f1a is the next step up.

I responded to this on corvette forum. I would get this with a brand new kit but if you already have a D1SC like myself upgrading to a F1A94 makes more sense unless you want the power of a F1X.

I was just thinking about upgrading from my P1-SC-1 to a D1-SC. Maybe I will wait for Bob to get more details posted about the P1X/D1X.

neverstop

yeah, if you are coming from a P1sc I'd personally just wait a month and get the d1x and then you can sell your P1 and recoup some of the cost too. One thing to consider is that based on what I was told is that there may be a slight decrease in mid range torque if the impeller is changed to flow more at high rpm that usually means a bit less flow at lower rpm so just depends on what you're looking for and we won't know for absolute sure until dyno comparisons are made.

sub'd for details, I was on the fence about a f1a upgrade from my d1sc.

Wonder how the new D!-X would compare with the F!-R?

It probably wouldn't be much of a comparison. The F1r should far surpass the D1x in capable airflow (power). There is little to compare in sufficient drive systems for both too. The F1r needs at a minimum a dedicated 8 rib set up with a stout as **** tensioner and even then you will likely experience at least some belt slip. With the new technology that Procharger is implementing on these new blowers, I'd be willing to bet that the D1x takes less drive power than a standard D1sc at max impeller speed. Which is nice as they are claiming even more power potential.

Bottom line is this, the D1x and the F1r are for completely different types of builds, so a comparison isn't even likely fair.

Now the D1x vs. the F1d or F1a could net some interesting results....

Is the D1X available for purchase and what is the price?

Thanks for the call, I'll get back to you asap. Bob

Would a D1x be better suited for a stock short block than the F1?
I'm currently thinking about going boosted and have a F1 ,so I'm curious if the D1x would be better for the street/strip (600rwhp goal).

Bob, this is awesome. I'm in the process of getting everything together for the kit I've been talking about buying for some time. Finally got the wife on board, but she wants me to have everything lined up financially before I go all in with everything.

I'm thinking of the D1X, Aster Bracker, Procharger FMIC, and the 3.4" pulley with a 383 (5.3L bored out with 4" stroke), TEA LS6 heads, and a 227/244 115 Supercharger cam with the Kooks LT & TDs, and FAST 102.

With the right fuel system and meth - 750-800rwhp with the D1X and probably 700-750 torque in that combo through a locked A4? 15psi or so?

Is this basically the same technology in the F1A-94 just in the D1 now? And how would the D1X compare to an F1A. Trying to decide between the F1A and the D1X... although the F1A-94 is also in my mind, but with my oversized BeCool radiator, I doubt that fits.

I really don't know anything about the D1X yet but I'd have to say it would be better for a stock bottom end than an F-1A. Thanks. Bob

Bob@BruteSpeed

iTrader: (16)

Steve, I still feel an F-1A would be a better blower for your combination than your F-1R. The F-1A can make 18 to 20 psi in a combination like yours and takes much less power to turn it than an F-1R. Bob

I don't know enough about the D1X to be able to steer you away from an F-1A, only time will tell. Thanks! Bob

Thanks, Bob. It looks like that extra 50-100HP is just coming from driving the blower. So that's a good thing. I don't like stress on the crank.

It's one of the things that makes me leery of the F-series. It takes a ton of HP to drive it. I know that's where a lot of the F1A-94 is getting it's increased power as well.

Subscribed as well. One of these days im going to break everything down and start over. D1x seems like a great option for an extra $300.

JakeFusion

iTrader: (7)

Agreed. For a 700-800rwhp street build, the D1X sounds like an excellent option. And I was just thinking too... with the Aster bracket and the CBR 8.65" pulley, one could run a 3.85" head unit pulley and have tons of belt wrap to max the blower out.

Bob, I assume the CBR fits with the LS2 water pump in place?

Do anybody know or have a link/chart of how much horse power it take to run the different prochargers at max boost. The p1, d1 , f1, ect.

Any word on pricing or availability? Thought these were supposed to be released in March.
