...or it would be nice to see a dyno pull with the gate shut vs. working.

 

At end of video.

Lol at ls1nova

 

Don't wanna push that much psi. Not gonna happen since I'm happy where it's at. Now it's time for big brake kit and safety mods.

 

That's because most guys don't put "F" series blowers on stock cube motors. Most guys run the P1 or D1 on stock cubes, then step up to the F-series once they go bigger cubes.

Your setup seems to work well. Enjoy it.

 

He is the night!

 

My favorite part of the video was watching the tire/bead at 1:25 on. It was dancin'.

 

That is the wastegate working. Tried it, not really a fan of wategates on blower cars.

 

Look at the specs of the d1sc vs f1d. They are basically the same other than the transmission. IMO the hp rating comes from the extra rpm u can spin the f1d over the d1sc.

 

That's like saying the D1 and P1 are basically the same, even the same transmission, just different impellers. It's not a lot bigger, but it is. An LS2 isn't that much bigger than an LS1, but it is.

 

I think Josepy made 810rwhp on a mustang dyno with his F1-C and 347. It was no where near done either. It also had a fuel issue of sorts.

 

I spent a bunch of time talking to procharger tech on the differences. I didn't say identical I said basically the same. I had my p1sc and the f1d next to each other the volute appears the same too. The next f1 I think is larger everywhere.

 

If you look at it the boost starts to hold steady around 5100 rpm... The loss in power comes around 5600 rpm... Even if boost stayed steady it shouldnt drop that hard and flutter as it drops... I would try leaning it out it might cure that up a bit.

 

Just a characteristic of a sc WG setup IMO. The parasitic loss multiplies more as the blower works harder but the boost stays the same. I'm gonna drive this for a bit and see if it's solid then maybe turn it up which will raise the boost and the rpm band at the same time.

 

You're correct. The F1D and D1SC look almost identical with the exception of the larger transmission in the F1's.

I've used both the F1D and D1SC and I'll tell you that in no way, shape, or form will they perform the same.

I've made 830 RWHP with an F1D at 55,000 Blower RPM's in a C5.
Not going to happen with a D1SC with equal RPM's.

From an F1 on the volutes are larger.

Nice job BTW with your car. I'm sure it's a fun ride

 

teh volutes are teh same size on the f1d and the p1sc. At least the physical size. THe insides may be different.

And thx its def fun.

 

I agree with you. Here you go. For those who don't believe what you're saying. Looks very much like a D1SC and P1SC

 

I believe him that they are very similar, maybe even identical in physical size, but performance is not identical just like you said.

 

How did you come to the decision to go with the D instead of the A and why ?

 

Car seems killer
Question: Since it fits into the current convo, i have a D1 (non SC), would that be more similar to a F1D since it shares the same max impeller speed (even though the gearing is less?) than it would a D1SC?

Just trying to figure out what I can expect boost wise out of it on a 403 (ball park range)

 

Found a good deal. After reading up on it and what it was designed to do (strong mid range tq) then I decided to jump on it.
