I never got a chance to do a before dyno as I bought the car then sent it to get the kit while i was still gone, but my car after made 505RWHP/480RWTQ and 400RWTQ at 1700 RPMs. THis was also while I am having consumption issues and we are pretty confident that when its fixed we will gain a bit more. Thats at 7lbs of boost.

Here's a copy of Badmonkey's graph after the magnuson, CNC ported heads, and cam, with LT headers.
We didn't have our dyno yet when his car first came in, so we didn't get a baseline, but stock LS1 F-body's with an M/T usually see 300-325 RWHP.
SS125, I snet you an email with the requested information.

That's all I got until the oil consumption issue is done.

Ill be getting mine dynoed on the 14-15th of this month. I hope it puts down some good numbers. It feels healthy and doesnt like street tires one bit anymore. I put a 3.2 pulley on the car but I have to key the crank yet because im only seeing 5#s still according to the map sensor. The car is running a ms4 with prc stage1 heads so its not "blower friendly" by the books but ill see what happens. Its been street tuned with hp tuners 2 bar i got 23 degrees of timing with 93 pump gas no knock.
As for the video. Did you get a chance to run the car without the lid on ever. Good god is the blower rediculously loud!
Ill let you guys know when it gets dynoed chances are i will post in the dyno section ill try to remember this post tho.

Well its a LS1 so its going to use oil : ) But All i did was take a hose from the rear of each valve cover and connected them and I am also running one hose from the pass side cover to the blower. There is some oil in the throttle body but its not sucking a quart in 100 miles like it did. Now its like 500 miles and a 1/2 quart which is pretty much what i was loosing N/A

Nope have not figured it out yet. I have done everything possible to determine what may or could be causing it other then tearing it down. Now its getting reviewed to make sure I did not miss something and then will get torn down to find the issue. I am disapointed rigth now I waited a long time and its still not right at the moment, and all the work was paid for months ago. I was hoping it would have been doen by now but I have a feeling it will be another 2 weeks before I get it back maybe, which is a huge let down. It's getting torn down now to find the issue. At this point I was planning on going to the LSx SHoot out but now its not happening. Just gonna have to wait and see how it all turns out I suppose.

Sorry about Hi Jacking this thread lol.
I did a leakdown test twice and Ed has done it twice once after the build and once while checking my work, I rerouted the PCV to a catchcan and vented to atmosphere, replaced valve seals, checked the blower's seals and gaskets (not much to check). I have fouled out at least 10 sets of plugs, and god knows how many quarts of oil. If I go into boost I start eating oil quick. Its gonna be my bottom end but I starting from the outside to make sure it was not something else, working our way down from the top end to the bottom. Hate to have it pulled all apart to find out it was something stupid up top, but I got a feeling its in the bottom end. It had new rings and bearings put in as well and was brushed. It did not start doing this until after the build. I just hope we find it soon this is killing me. I may may not see the numbers he is getting but we figure I should be up around 530 or so on the HP when I get it all figured out.
