Was it rubbing on the pinch weld on the drivers side? I had to trim mine down quite a bit (a lot more than i wanted for sure) to get clearance. Funny I looked for this in your pics and it seemed like you had good clearance. Almost made me wonder if I had my turbos on the wrong side. I basically just cut the pinch weld down to the curve in the metal so I had as much clearance as I could get. Obviously that motor is going to move and that was awfully close before trimmed. Not all that bad considering this was literally the only "body" modification I had to make to the car to get it to fit. Some kits require you to cut up tons of stuff, which Im not a fan of.
Yup, I just trimmed it back to the frame. Also the On3 gates are huge, a trial mvr-sport or whatever is like 2" shorter than an On3. When I have some extra cash Id like to replace the gates on the housing with a Tial just to save space.

Saturday was dry enough to get some testing done, no more rattling. I also unhooked the top two waste gates to see what would happen. Surprisingly the car now makes a constant 6psi like it should! Unfortunately it started raining again, I installed the block off plates I made where the top two waste gates go. I want to do some more testing to check for boost creep and make sure my boost controller works. If everything works I feel like this is a huge advantage to the system and only using two gates instead of 4.
Also should have everything for my external fuel system, hoping to get that installed this weekend or next week. Id like to get it back on the dyno soon, now that Ill have proper fuel and boost control. There's a roll race not to far from me Nov 10th id like to attend.

Im hoping they really arnt needed. The system worked great when they were not hooked up to a vacuum source, which I think means they shouldn't open at all? Im itching to test what happens with them completely removed and blocked off.

Was able to drive the car for awhile last night with good and kinda bad news. Good news is, looks like I can confirm that blocking the top wastegates off worked. It held boost very well from what I could see while watching my gauge. Bad news is it looks like my reduced power probably is coming from the abs modular from up front or the ebcm what ever that is called. If I pull the abs fuse it won’t go into limp mode, second I put the fuse back it will go into limp mode only when traction control is turned off. If the traction control isn’t turned off it will not go into limp mode, also I’m not able to put it into competitive mode now either. I made a quick design of how I want to start on my axle back. Hoping to have that done soon, the car likes to throw fireballs.

I believe Borla makes straight pipes like that. Glad to hear the wastegate blocks worked, I'll definitely be following suit. I swear youve had the worst luck with this car, glad you have some perseverance haha. Id have sold the damn thing by now! So youre holding steady at 10psi? Are you running the manual boost controller off of just the bottom ports as ON3 suggests?

Holley also makes a system just like that.

I've been running the blackheart system for over a year now and I love it. I'm using the one with mufflers though, not their straight pipe system. I'm gonna have to sell it and upgrade to a 3 inch exhaust system which sucks but I'm hoping for a deeper tone.

I'm 99% sure I'm going to order the blackheart with mufflers. No valves, just the muffler system. Shikaitsu, can you confirm the "main muffler" is straight through 3". Why would you have to sell it to upgrade? Looks like it is 3" system already.

Honestly not sure, I wanna say .82 but not positive. Im sure a spec'd cam is better but BTR has a cam made for twin turbo 6.2's which is what I have. There service was pretty good too, I called and told them what I was doing and they put together an invoice for me with everything I needed. Glad I did that because there was alot of little stuff I would have missed.
