congrats mate! REALLY nice setup there! and im soooooo glad you fitted the A2A to. it will make a big difference. i was would love to see some data logs for this thing. be really intresting to see how fast that turbo would come on.
Keep us posted!![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Chris.
PS how much boost is the blower alone making? it would be nice to see some logs for presure before the SC. then you could compare to a 'similar' turbop only setup to see just how much difference the SC is making.
Keep us posted!

I check out a log today and at an 8mph roll, it went from 0% to100% TPS and 10psi of boost in exactly ONE second! Seems the blower isn't having any trouble sucking though the intercooler and turbo, and then spooling the turbo.

Blower with this pulley should be making about 7 psi.

Just thinking about this kind of stuff, have you thought about pre turbo meth/water injection??? i have heard great things about it. if you conbined it with the FMIC and a little meth befor the blower, and maybe a little after, you should have the temp thing totaly sorted! lol
keep us posted on results. be intresting to see if you can get the spool time down even further. i can give you some ideas if you want!!!

I'm not having any IAT issues, even at only 10 psi of boost, I see very low temps. I just got down to AZ, and am going to be working on the tune and probable hit the track with it. I will let ya guys know of what I think about a little more once the boost tuning is more sorted out, it's still really fat and low timing to get me here.
But so far I'm pretty happy.

Props on a very nice build. Truck looks great and you have the right to say you are one of a select group of people who have done that. Best wishes finishing the project and I can't wait to see some videos.

wow. you are definitely putting a good amount of time and effort into this, and i applaud you. I am really looking forward to seeing the results.
i hope it is a beast of epic proportions, lol. Good luck bro-ham.
p.s. get that dyno graph up as soon as it is running properly with the new converter and turbo. i want to see the torque curve.

So been driving it for a while, even took it on a road trip to AZ. Ran it at the track once and it was less then stealer. The small p-trim .96 turbine on the turbo and 38mm WG are just WAY to small and choking the blower BIG time. Huge boost creep! Getting almost 15psi on a 7psi spring and WAY to high EGT's, like close to 1700* and not making the power it should for that boost.
The converter is way to loose, (4200 foot braking) so I can't even keep the RPM down where it does make good power (the bottom end on the setup is AWESOME!!!). So I got a BW S475 T6, large frame turbo and ordered a Circle D 2800 265mm single disk 4l80e converter that should be here next week some time. Also got a 50mm Synopsis WG to put on it too. The hot side on the turbo should free up the back pressure a TON and let this thing breath. It's a 96mm turbine wheel and a 1.36 A/R. Good thing I have the blower to spool it, lol. Gonna run a 4" down pipe too.
Also gonna ditch the intercooler in between the turbo and the blower and just spray a M3 meth nozzle pre-turbo along with the M15 that is currently in it pre-blower. IATS haven't been a problem at all. The most I've seen even with heat soak in the 100* AZ heat were only in the upper 140's and most of the time in boost on warm days where more like high 130's. I think with this setup, everything should be pretty optimal and should preform quite well .
The new turbo came today
it's HUGE ![Icon Lol](https://ls1tech.com/forums/images/smilies2/icon_lol.gif)

Compared to a TC76 About the same size compressor wheel, but the BW has 1 more blade on the wheel and extended tips on the blades.

Here is the BIG difference, the exhaust wheel is WAY bigger. So that's like having a MUCH bigger motor with more leverage to drive the compressor.
that and it will make for a much free flowing exhaust for the blower.

No it has a cross over that feed the driver side into the back of the pass side log. This is a very popular design for truck kits. My buddy has a kit like this that has ran a 10.6 with a stockish 6l and a TC76BB in a 4900lbs 4x4 reg cab truck up here at altitude (4800') Not to bad...
