LIttle P1 that could.... Procharged S550

Can’t really see it after everything is back together.

wow , nice fix how much flange work did they have to do to upgrade the bov- or was it a simple swap - I never had any boost leaks with my stock procharger bov pro flo but when I down pulleyed I upgraded to a big red open and the car actually drove better with no surge at all . on the stock 4.63 pulley on the dyno I would see 11.6 @ 7400 rpm.(500 da +/-) I was also trapping 136.xx mph

How did you know for sure you weren't leaking boost with the pro-flo?

10 # pulley - +/- per procharger producing 11.6 #'s with a open air cleaner, boss intake and 1 7/8 headers to no cats to 3" exhaust pipes to a 5" mufflers- these remove most boost restrictions. and compressor surge on quick decel tells me I wasn't loosing boost or if any very little . no I never gave it a compression or boost test officially- 136mph trap speed some what also verified this.

any pics of the final install?

Hope this helps. Looking from above driver’s headlight into the back of bumper

Is that some sort of filter over it?

No, in the pic you see the blower discharge with the blocked former pro-flo tap in the center of pic. Slightly to the left you see the vacuum line going up into the turbosmart that’s at the top of the pic.

Wanted to update that all the needed fuel trims adjustments are complete and I’ll be likely going this Wednesday to the track,

 

[Bill@HPTuners]

which track? PBIR?

Thanks, this might be my last track outing. In the fall I’ll be back with either converter or e85 and matching rear F14 wheels.

 

[Bill@HPTuners]

yeah converter/tire will likely be my next mod if I do mod it further. I'm pretty happy with where the car is now, 1st & 2nd are pretty much useless on the street, converter would just make it stupid on street tires. Surprisingly in my part of FL E85 is hard to come by so I won't be going that route which kind of limits my power options.

Buy by the 5gal pail.

a 3mph trap speed increase might have Bill thinking that pro-flo is Bunk, haha!

Wow you nailed it!! 20 degrees hotter than last time out and with a slightly worse 60ft....10.58 at 131.5

 

[DarkMach1]

Looked at log last night. That was on slightly less timing and, due to miss communication, a lower shifting tune by 300rpm. Lol

I need to address my BOV, haha!

 

[Bill@HPTuners]

awesome numbers, boost still holding strong at 10psi during your 2 runs?

 

[DarkMach1]

10-10.5 at 72-7300, yes. Up from 7.5ish at same RPM before. I’ll post a video of the pass later.

 

[DarkMach1]

Not that bad of a launch for no converter if you ask me. but I think it could be a touch better

That IS AMAZING! I need to figure out which BOV to get that will be easiest to add to my piping..
