yea thats the problem, cant really fine no "real" info on the two being compared on a engine that most people use
most likely ill be going with new PRC 250cc ls3 heads from TSP and a ls3 intake on a 408ci
now if im only going to gain 10hp and spend $1000 i dont see it worth it

typically, we can 10/10 with just an out of the box FAST. To most of my customers, we dont sell it unless they are looking for max effort.
Do you know what the 107 is/was worth? I didnt think Nick was making them?

99.9% of people do not need a 102mm throttle body,everyone should be running a 90/92mm. Its the runners that make the power, not the size of the opening for the throttle body.

I did on my 402ci. I had l92 ported heads and a l92 intake. Went to a fast 102 and gained nothing on the dyno. I then went to trickflow heads with a fast and gained nice over the ls3 stuff. then had mammo port the fast 102mm and gained again. You could get the ls3 intake port matched and make a small gain..

Id say those are abnormal gains Kevin, but more on track with the LS7/Gen3 FAST, which is where it should be.

Hope you're doing well.
I've been told Nick isn't doing the 107mm anymore. I was lucky to get this one.
Here are the numbers:
Here's the dyno chronology:
427 Old Cam............................................605/588
427 New Cam...........................................621/601
427 Port Matched FAST w/ 90mm TB............633/616
427 Shawn Miller massaged FAST/107mm TB..656/614
It looks like Shawn managed to get the FAST to produce 35hp with the FAST. Not too bad,

That being said, I made 530RW on my very mild build 403 with a ported L92 car intake and 90mm TB.

I think Shawn and I both invested in making the FAST work on my build. My $$$ and Shawn's time. I don't think he's really interested in doing any more unless it's part of a complete build.
