I just got a good look at my TL files from last week at the track and I see that my boost is going really weird. Here are the frames of one run: 5inHG, 15.5Psi, 13.0Psi, 12.5Psi, 11.5Psi, 13.0Psi, 14.0Psi, 14.5Psi, 15.0Psi, 15.0Psi. Another one goes: 6.5inHG, 14.5Psi, 13.0Psi, 13.5Psi, 14.5Psi, 16.0Psi, 16.5Psi, 17.0Psi, 17.5Psi, 18.0Psi. And the last I looked at went: .5Psi, 15.5Psi, 14.5Psi, 14.5Psi, 16.5Psi, 17.5Psi, 18.0Psi, 18.5Psi, 19.0Psi, 18.5Psi. What could be causing this? Is it a mechanical problem or something else? Like could it be the wastegate solenoid? I wouldn't think it's something in the chip. The thing I'm mainly thinking is the puck itself, I recently took the old one apart and had a stainless steel bolt welded in place of the mild steel rod. I used the same size, 5/16. The bushing it rides in is also stainless steel. Could it have something to do with the expansion of the metal at a certain temp? Thanks for the input. I know I need to take it apart, I'm just looking for ideas on what I need to look at/for.
I took it all apart and found a few things wrong. I thought it was binding up on the inside somewhere but after taking it apart, it actually was binding on the outside with the way I had it put together, so possibly some grinding here and there could fix that. Also I found that the flat arm that holds the puck was bent backwards. This was the same piece used with the other setup and I had the ss bolt welded to it in exactly the same spot, the only thing I can figure is either something with it not closing all the way and somehow the air pressure against it bent it or it was just from the fact that they didn't put any weld along the top(they welded it on the edge where the rod and flat arm were flush, they didn't put anything on the other side) like I had asked. I'm not sure how much more strength a small blob here and there would give it, ie would that be enough to keep it from bending back over the rod? And the last thing I noticed really bugged me and as far as I can tell has been this way for awhile. It seems that when the puck is closed the puck isn't completely covering the hole. It's not a large gap but it's a gap regardless, anybody have ideas on what this could do to boost? It's never been slow on building boost, it usually builds about 15psi from one frame to the next with TL. I'm waiting for a response from someone about fixing it for me and while it won't be as cheap as my initial try, only $6 my first try, I hope that it will eliminate any further problems in the boost area. Hopefully with a better centered puck I can open the hole even more and finally get some rock solid boost control.
