I just put my order in for my F1A with Bob at Exotic Performance. He is awesome to talk &, crap load of help.

Should have it in about 1 to 2 weeks. Hes going to set me up with about 15-18 pounds of boost. Cant wait to hear it whistle again.

Ive found only one other person on this forum with the F1A is that correct??

Ill let you know some #s after the install and the final tune.

According to the FedEx tracking page, my F1-A is suppose to be delivered on 7/5 (ordered from Bob @ EPP also...GREAT guy to deal with and excellent pricing as well!!!) There are a few guys that hang out on this board that are currently running an F1-A. I'm sure they will chime in and offer their opinions on their set-ups as I know they are happy with the performance they are getting from their Prochargers! What is your F1-A going to be bolted to??? I'll post some pictures of mine when I receive it and get it mocked up to the motor. It's cool to see more and more people here stepping up to some larger head units. There are guys here making some pretty incredible RWHP numbers.

I wasn't sure whether to get the D1SC or F1A for fear of it being to big of a blower for a daily driver. I definitely made the right decision. It is a great blower. It is apparently more efficient because I'm making more power at the same boost level than my P1SC. I've still got lots of room to grow down the road too due to the steeper internal gearing. You need to have a built engine for an F1A because its not capable of anything less than 8psi of boost.

Agreed!!! It was the 5.40 to 1 step-up ratio and the 74,000 max impeller speed that sold me on the F1-A unit. I won't have to spin the motor I built much past 6000 rpm when using the 7.65" crank pulley and the 3.40" blower pulley.

I’m putting it on my 95 lt1 Z28. The motor should take this blower. Its all forged 383, 4 bolt main.
97ws6pilot you said you gained power with that blower at same boost? Did you get any dyno runs for exact #s?? This past winter I took off my p600 and put my own FMIC on with a D1. I took it down to a guys house in IL and meet the guy from madz28 to tune my car on the dyno. Well lets just say it didn’t go so good. On my old set up with the p600 I had to much fuel. With my 60lb injectors and the FMIC and the D1 (15 pounds of boost) I didn’t have enough fuel pump. We also weren’t seeing 15 pounds till around 5500 to 6000 rpm. Mean while we blew the injector FUSES. Never seen that happen b4???? We ended up running it 3 or 4 times best was about 570 RWHP at 5500 rpm (lean).
I took it home and got it off the trailer and took it for ride. That’s when I figured out the blower was junk. Some how the impeller spun loose. That’s right spun loose. Guys at Procharger said they havent ever see that.
So I hope with this blower all my troubles are going to be gone with the blower issues.

Did you ever resolve your "fuel" issue? What pump are you running? Hi or low impedance 60# injectors? Did you keep those same size injectors? I'm running 95# injectors in mine although slightly larger than needed, but wanted to be safe. I don't have the injector size formula in front of me, I would tend to think that 60# injectors may be a little on the small size for a 383 with your new blower. The F1-A should lay down some strong dyno numbers, providing your fuel system is adequate.

ive seen ls1s put down some crazy numbers with 60s, youve just gotta retune it for higherpressure and run the 60s at like 60psi rather than 41

So, asuming you have a built motor for the boost, and with a D1SC you are only capable of 14-15#'s of boost. How much could (or would) the F1-A make on the same setup?

What is the difference between the F1, and F1A? Does the F1A have more power potential, and does it fit the same brackets as the D1SC? Also, if anyone here knows, does the F1R fit in the same brackets as the D1SC?
I want to step up eventually, hopefully I won't have to make new brackets.
Thanks, Steve

I was running a P600-B for my first blower on this car and I'll be using a completely different FMIC set-up and motor...so no numbers to really compare, but I'll sure post some numbers with this new combination, hopefully soon as I just received the F1-A tonight!!!

Ponyhntr will probably post up some of the information regarding which head units will fit which mounting brackets. Although I do know that the F1-R unit is a much larger unit and would probably not be able to bolt to a D1SC bracket.

There is a link to a page with some good general information about the various Procharger units: http://www.procharger.com/models.shtml

F1 or F1A will bolt up to a D1SC/P1SC bracket. It requires that about 1/4" be ground off the corner of the block. Also requires a little grinding on the ABS bracket if you still have it. It literally took 15 minutes to do the grinding.

CALL911

Do the pullies match up the same from a D1SC to an F1-A? I have always said I am happy with my 614 RWHP, but am just curious of how easy it would be to change to an F1-A, and what kind of power increase/boost level I would see compared to the 614 RWHP, and 14.5#'s of boost I am currently maxed out at.

Ponyhntr

Like others have said, the P1SC, D1SC, F1, F1A, F1C, and F1R all fit on the same brackets. The only difference is the F1C and F1R's have a 9.75" volute versus the 9" on the smaller ones.

Ponyhntr

Everything from a P1SC to an F2 will take the same pulleys.

Ben, if you were to take an F1A and simply bolt it on in place of your D1SC and max it out (3.70 pulley at 6600 rpm), you could realistically see a boost increase of 5-6 psi, maybe more.
