OK just got back from BOOST did about 10 dyno runs. Didnt get my 1000hp mark but oh well was very close.
The first run was at 11psi and did 790rwhp and 770rwtq
Second run was 16psi and did 891rwhp and 830rwtq
We couldnt get it to go past 16psi on the dyno so we put a camera under the car and dynoed again and found the driver side inlet sucking shut thru half the run. Keep in mind we had already stented the inlets so we wound up having to put in 2 more small pieces of pipe to keep it from sucking shut.
We finally got it to hit 18psi it put down 901rwhp and 801rwtq
We did a last run playing with the boost controller and we didnt expect it to go past 20psi and around 5200rpm it was at 18psi the went and hit 20psi and was still climbing so he let out of it at 5200rpm
It did 930rwhp and 819rwtp
All in all i'm happy with the results this is just on a safe tune nothing extreme no meth just a race pump gas mix. We had problems with the car spinning on the dyno also so not sure if we really got a clear view of what it really put down.

Wound up loosing TQ from the stock APS turbos to the New LG turbos but thats what happens with a bigger turbo. At least with the LG turbos the graph climbed all the way to 6200rpm. Didnt get any video of the last runs since we were having trouble with the inlet hoses and the boost controller and the spinning on the dyno but a fun day none the less.

Some good results and some interesting results. That torque sure does go way down from your standard torque reading.I was expecting torque to still be a lot higher than hp.
Timing can do a lot with torque so might still be a lot of improvement there possible.
Disappointing about those tubes and the simple stenting needing extra stenting to work.
Sounds like a hard tube is the answer. And would think you should be able to get an hold 20psi with 10psi spring . It looks like it might take 25 or so on your combo to yield 1000rwhp ,turbos should be capable of past that even if they are true 70lb/min turbos.
Still I would be plenty happy with 800rwhp from the turbos at pretty low boost and just use some spray to give me the occasional 1000rwhp.
Well it will be interesting as Tom and Barnat dyno their lg turbos. I will maybe have some of my own next spring. So you guys keep testing them out and especially want to see how they hold up running near 20psi on bigger engines like 402,408 or even bigger.

very good start i want to see the outcome from the dyno
what was the IATs at ?
timing? AFR? things like this is what i like to see
IDC?
congrats bro how does it drive
does the shop have you running long/short tem fuel trims or do they just keep the car in closed loop all the time?

so dont think we saw what it was really doing. I would like to see how everyone else does with these turbos though. I'm just happy they are holding up to the boost unlike the crappy APS turbos.

Had some cooling issues with it though after each run car didnt want to cool down even with my big *** radiator think we are going to move the intercooler more forward and make a space between the intercooler and the condensor and radiator.
Driving on the street is fun with it all my goals were met with this build now just need some track time but that is going to need to wait til next season
