im wondering what kind of power can i make if I go to a 408 with a d1, and i switch to a front mount intercooler, is the blower going to be too small for that many cubes? are my 60lbs injectors going to be enough? what kind of fuel system will i need?

I just got through going through the same series of questions you just asked. Here is the thread.

Im going with 60lb injectors, larger twin pumps and a BAP.

with a 408 you should go with F1 . ... epp>>>>>>>>>>

if I set my motor up with 9.2-9.5 compression what kind of power could I expect from the d1sc, also how many psi of boost if i max it out? I have more important things to spend my money on right now as far as my car goes versus spending another 2900 on a new head unit when mine is only a few thousand miles old. i also like to drive my car on the street a lot and the f1a whine might start to get on my nerves, but dont get me wrong if I cant get the hp I want Ill get the f1a and turn up the radio

All depends what you want? Do a search.

Things to consider would be the 60# injectors probably are not going to be up to the capability of the F1. Definitely need a aftermarket fuel system - dual pumps, -8 AN feed, -6 return, boost referenced regulator at a minimum

What kind of trans? 4L60E or stock M6 probsbly won't live long without being built and having a good clutch set-up.

Headers and exhaust......if you are not running 1 7/8" tubes and tru duals then why go with a BIG supercharger?

Do you want A/C?

What about extended street driving, what climate do you live in - how hot does it get in the summer. Be sure the cooling system is up to the task. A/C just makes it more difficult.

If driveability is a concern think these things through.

oops. I should have read LMT0705's sig.

Just stick the D1 on the 408...

I had a custom 8" crank pulley made in order to get max impeller speed without have to go under a 3" blower pulley (belt slip). My cam is somewhat mild. I am getting 13PSI on my setup, I would think dependant on how well your motor flows and the cam profile, you should see at least 15 lbs...

by the way my 60# injectors are running 75% IDC, however I have a BRR base pressure @60PSI and see 73-75 PSI at full boost, and am running pure meth....

I would go with a bigger procharger, IMO... I max a D1 out with a 347 and KP might chime in with his F1a on his 347 and give his .02

Check out this T/A that was an SLP 402 that had a D-1SC in it, that we redid a lot of thing on. It made 757 rwhp. It made more boost than I thought it would, but an F1A would not be running out of steam compared to the D-1SC. Bob

I run a D1 and am looking to upgrade to an F1 because it's out of steam on my 402. The only reason I got the D1 is I had it on the stock motor before that blew up.

I have seen 750rwhp in 100deg heat without meth or alchy, but to me that's not enough.

Where did you go to get the custom pulley?

Its pretty simple really, look on procharger's web page and if you want to make more horsepower than a D1SC can flow, pick a bigger blower..

As long are you are in within a reasonable CID range (270-400cid for example) the blower is going to support as much power as the amount of air it can flow and thats it. So pick your blower based on the amount of power IT can support, not what the engine is capable of doing.

If you want 800rwhp it most likely wont happen with a D1SC unless you have an ultra efficient engine and drivetrain.

if bob made 750s on a mustang dyno he should be able to hit 800 on an unloaded dyno right?

I have no idea, I dont pay much attention to chassis dyno numbers. But according to procharger 925 is max flywheel horsepower. Take the loss from the blower itself and the typical M6/12 bolt drivetrain and 800 or so at the wheels is about it with everything perfect I would think.

If I was shooting for 800rwhp to start with I would like to have a little more airflow than I need, even though its a tough tradeoff with the extra noise IMO if you want around 800rwhp. But most people always want a little more after they get used to it. I am no in no way anti-D1SC, its a great head unit and I still have mine and use it quite a bit. If you already have one I would try it, swapping to an F1A or something doesnt take a lot of work if you want to upgrade down the road.
