Ok, I tired swapping ports still did it. I took the wastegate off and decided to add another spring to it. Now it says I'm boosting at 13psi, so I guess I'll leave it there since fuel cut is right around the corner... I still don't know what could have been the problem, so I'll just not run a...

Ok, I'll do that. I'll keep you guys posted on what happens..

^^^ Weak spring? So I should go higher than a 10psi spring? I have the vac hose on the bottom half of the wastegate port. Left the port on top open for the vent like it shows in the diagram. So I know it's connected right, now why would a weak spring do that if I want to boost more?

Before I got a boost controller I had a vaccum hose straight from the compressor to the wastegate. And it's a 10psi spring. Now when I go to put a boost controller and turn the dial it still says im boosting 10psi. I go to turn it up some more and still I get 10psi. The boost controller is...

Sorry about that, but yea I can post how I have it connected. It's similar but the vent tube is on the top of the wastegate, BC is T'd in between the pressure source and the wastegate. Again, the ball bearing is on the pressure side and the spring end is on the wastegate.

ok, it went past 10psi, I stopped it at 11.8 psi. It's digital btw. So it's the wastegate I believe is the culprit?

Ok, so I drive it w/o a wastegate just to see if it will go beyond the spring rate? Should I plug up the nipple on the comp housing? Also won't I hit FC since I don't have a wastegate.

38mm turbonetics wastegate.

I don't really feel a power increase, I did noticed it spooled quicker though. It's like the wastegate just want to keep opening at 10psi every time. I did almost have it completely closed at one point during my runs and it still says 10psi thus meaning the wastegate is opening at 10psi. Could...

hmmm... I'll check them tomorrow but I doubt it, I only have 4 couplers throughout the whole system. Thanks..

I was driving the other day, and to be honest I've never really looked at my boost gauge that much to see where I was at on my big single. Well I finally got around to look at it and say I was only boosting 10Psi. So that was my External Wastegate spring rate. Now I made my own Boost Controller...

Really? I had a 1j before on my white 87 supra and yea I remembered that the power band did cut off or so at around 6200 or less been so long but it was noticable. For the 2j it was almost the same ( a little lower on rpm) but 2j's redline sooner so our power band isn't so high on the twins...

Ok, that's cool I appreciate it man. That's what I thought it would do, is boost up my mid to high end range, and that's pretty bad ass that it gives you a slight gain in low end especially a sooner spool. Thanks again can't wait to see the dyno sheet.

Cool I'll look him up on sp. Thanks ---------- Post added at 06:31 AM ---------- Previous post was at 06:24 AM ---------- When you say across the board could you specify rpm ranges? I'm currently on a mp t70 turbo and I hit boost at about 3500-3800 so will the rpm range drop lower or stay...

Hey guys, I was just wondering what power bands are you guys getting on 264 cams on a 2j big single. I did searches but couldn't find any. I was even looking on hks's site and brian crowers too to see if they posted up some power bands, and it looked pretty decent, but I wanted to get you guys...
