With turbos that size, you can figure app. 30 whp difference for every 1/10 BAR.
And THIS is why I really like forced induction! While the NA guys pay big bucks for small gains and sacrificed drivability turbos just haul ass! I look forward to numbers on pump and meth at sane boost levels when time allows
Well these turbos act a little bit different than a normal turbo. On 13.5lbs it made 554rwhp or so. So ALMOST 1bar it made 554rwhp. The turbos make like ~20rwhp .1 bar at REALLY low amounts, but as we get above 20psi+ it starts jumping up 25+rwhp per PSI almost! It is really amazing what these billet turbos are able to do. For example we made 77Xrwhp on 24psi (sustained) and made 83Xrwhp on 26psi (sustained).
Sean when I say low boost I mean Pump + Meth. I would never run more than 1.1-1.2bar or so on 93oct ONLY, with these turbos at least. Though keep in mind I am on wastegate only 90% of the time that I'm driving because there is no need to tap into 700-838rwhp. Most cars that you will run into on the freeway on the way to work can be dealt with, with just 550-600rwhp. Yes there are the occasional cars that need more, but 99% of the time its like a car that MAY trap 125mph that messes with you.
Another thing to mention is how these turbos hit, like when they go into boost. It is VERY violent and not the usual nice fade into boost. As soon as they spool it spikes the boost hard hince why it white smoked all 4 tires.
Very nice numbers produced from your build. I've had great experiences with Boostlogic with regard to my Supra; I'm sure they will continue to bring a quality product to market for the Porsche crowd as well.
As others have said already, enjoy it in good health.
Sounds a little like a Supra power curve except it's not showing that on the dyno sheet. Actually Supra power levels too until you hit big boost, the P-car heads\cam must flow a bit better than the Supra
Can I get specifics on what the BL900 kit consists of; feel free to pm if you desire.
Thanks & drive safe!

It made 554rwhp on lower timing on 13.5 spikes, The car easly make 6XXrwhp on 1.1 bar. But with pump/meth we will see 700rwhp safely. The car also 1.5 bar made 788rwhp sae Friday. We never redynoed it on wastegate with the final tune. I cant wait till we run some 60-130's!

Big motor Big shot
147 traps/ 5.27 60-130 First pass with the new setup!
The Boost Logic kit that I have consists of some one off pieces, but for the right amount they could be made again. But it basically consists of these pieces:
If my math is correct 26 psi/ 14.7=1.76 bar....damnnnn that is a lot!
Those are big numbers Chris, congrats and be careful (at least for a little while).
Yup you are correct it made 1.75bar sustained, but we saw spikes as high as 28.7psi. Those who've actually watched their EBC's while on the dyno or had a passenger watch them know that you spike usually about 2psi more than you actually see sustained. I know personally on that 28.7psi spike that the boost settled down right at ~26.5psi or so. I think that pull I made 831rwhp/790rwtq SAE.
I forgot to mention when I dynoed on ~1.5bar the first pull of the day it smoked the tires on the dyno. Granted it was on cold tires and it was a little bit cooler it still almost shot itself off the dyno LOL! I had Matt (Lil Powell) in the car the whole time after watching the Boost Controller and to add weight for traction!
