You got me Nouman! 
I thought that by the heading that yours was finished! I was smiling for you!
That's one loud blower! Though it is one SWEET looking setup and I'll bet it'll haul the groceries..........especially with the A4!
Congrats Arun!

a) Is it 6-rib or 8-rib
b) What's the size of pulley
c) How is it that it makes boost so fast, while revved it from idle to 3K and I see the boost was jumping almost 7-8psi?
d) What's the max PSI set for it?
The engine sounds very responsive!

Some of the reasons it builds boost faster than normal is:
-The step up ratio on the F1 is 5.4 vs. the 4.1 of the P1 and D1SC
-The effect of having a large head unit on a 347.
Mine was exactly the same way. It was instant... and tons of fun.

Did he drill out the bracket or get a new one from the D1->F1R. There are additional mounting holes.

Some info on Arun's setup
"It’s an 8 rib, 8” crank 4.13 blower pulley,
Max boost-who know’s? I can go down to a 3.65 pulley before the blower’s maxed out( NMRA Renegade spec 5.0 stepup 74000 rpm)
The reason your seeing boost is just what Cartek Max said. It’s just a little 347 with a big blower.
The blower flows 2000cfm compared to the 1400 that the D1 did. The bypass is struggling to get the air out-it has one Greddy Type R heavy spring ( 1-7/8 piston)-might have to add another one.
Another reason is the belt isn’t slipping either-I fabbed up some custom idlers to get max contact area on the belts."
