Thinking about Procharging
Thinking about Procharging Im thinking about Procharging my current setup and was wondering if a D1 would be sufficient. I dont really want to pull the trigger in an F1 since I really dont plan on using it to its fully potential so I figure a D1 would be a better choice.
My current set up is:
LS3 Aluminum Block (418 CID) 4.080
Callies CompStar (Dragonslayer) Crankshaft
Callies Comp Star Connecting Rods
Diamond Racing Forged Piston -10cc Dish
Mahle Motorsports Plasma Moly Rings
Clevite H Bearings
ARP Bolts Throughout
Cometic .040 gasket
Trickflow 235 heads with milled to 62cc
Morel lifters
Flowtech RACE-Series Three-Piece, Heavy Wall Pushrods
PAC 1521 Dual Springs
Jezel rockers
Flowtech Ported FAST 90
Kooks Signature Stepped Longtubes 1/78-3 (no cats)
Borla exhaust
FTI Transmissions 3800 Stall
Transmission Physicans built 4L65E tranny
B&M Tranny cooler
Lingenfelter Hi flow fuel pump
Melling oil pump
My compression is 11.4 right now so I plan on swapping my heads out and getting either 75 (10.0 compression) or 80cc (9.6 compression) heads which should drop my compression.
So with that said what are your opinions? Are there any other things I should take into consideration? Any advice is appreciated

Despite the fact that the D1 has proven itself on several big cube applications, I still think you should get an F1A and pulley it down until you eventually want to run more boost (which will happen in only a matter of time). I just took a glance at your sig and saw that you had 45# injectors, you'll definitely need bigger injectors once the blower is installed. What are the specs of your current cam? Other than that, I really can't think of much else but hopefully other more knowledgable people will post up to answer you question and give their opinions/advice.

I have seen several people step up to the the f-series after thinking the D1 would be good enough on a larger cube engine. Its more cost effective to just get the f-series now and use the pulleys to adjust your boost/power level.

All those nice parts and not wanting the boost of an F1!? A D1 will make a lot of power on your setup but you will be spinning it faster than an F1 at the same power level. Therefore the blower will wear out faster and you will upgrade to an F1 anyways. Go with the F1 it's bigger so it looks cooler and it has more potential to make more power. If you do not want all that power just go with a huge pulley and let the F1 barely work until that is no longer a good enough fix and you need more power. Trust me hp is like crack and I am sure you have learned this by now, you will always come back for more.

The D1 worked out fine on mine. Outran a few Corvettes with F1's......
I was looking for the 'quietness' of a D series for my street car. I think I could have gotten 9.60's out of it in primo air. Last year in Memphis I went 9.80's stuffing the brakes at 1000' with a 14* tune it at 3810#.
I also wasn't interested in the FMIC set-up, don't car alot for the looks of them in a SS and I didn't want to cut up my car to make it and the F1 fit. So I guess it depends what you want in the end. If none of that matters, get the F1.
Nice looking engine, I would shoot for the 9.5:1 number with the F1.

Go with the F1, F1A or F1C. You'll be happier you did it to begin with then need to get a different blower later on. Now with that being said, easily over 700 is do-able with the D1. If a D1 will meet your end goals then by all means do it. If you ever want to or even might think about turning her up, go with the F series.
Thanks for all the input. Looks like I'm going to start looking at the F1 hopefully I wont have to do any cutting or mods to the body that will be a deal breaker ( It will be dependent upon the extended cost that I "might" have to incur) and I will end up going with the D1 instead.
Currently I'm at 500/495 at the wheels with my current setup, 10.9 130 at the track through an A4. I'm hoping to go low 10's and maybe a high 9 with the new setup on a conservative tune.

What do you have done to the fuel system? From what I can see, you're going to need more fuel. I started my turbo project and totally under estimated the fuel requirements... put me $2k over budget right out of the gates.

LOL! heard this one before. (D1 is all I need) till you want more then someone on this site will be getting a good deal on a slightly used D1SC head unit because your coming out of pocket for an F1A unit to feed the boost addiction Just get the F1 now and be done with it

Does the kit you reference have twin or a single front mount intercooler? What hp is the fuel pump capable of handling with an F1A?
Tom
One pump is good for somewhere in the 600 rwhp range, adding a second pump will get you somewhere in the 700 rwhp range. Past that I'd get a whole new fuel system.
