Power issues
Ok, so I finally got my turbo kit on my new motor and was getting it tuned, problem was the power dropped off like crazy after 5250rpms, and this was at 14psi. We found out that VTEC wasn't engaging, but it had voltage, etc. Later we had oil pressure issues, and on my way home the oil light came on and I scared myself shitless. I have no clue yet if a bearing ate it or not, but I was wondering what could be the cause of such oiling issues. I had no issues on the motor till it was turbo'd. I had the ENDYN pump and whatnot to try and improve the oil pressure to prevent this. Any ideas what might be causing this oiling issue?
Ohh, here is a dyno sheet. http://preview.nbazar.photosite.com/...2375374950.jpg Any clues other than VTEC not kicking in that would cause this? |
Re: Power issues
Has anybody ever seen a dyno chart like this? I am kinda confused as to what I need to fix besides VTEC, but I am really curious if anyone has seen a dyno graph that curved like this.

Re: Power issues
Where is the oil source to the turbo hooked up?
I´ve seen someone that hooked up it somewhere on the head and the turbo was "stolen" the pressure.. no vtec, etc.. |
Re: Power issues
back of the block, stealthmode oil kit.

Re: Power issues
even if vtec didnt kick in, I dont think the power would drop off that bad, yes it would gain as much but it wouldnt just drop like a rock

Re: Power issues
anny noises out of the engine after running it at the dyno?and is the graph shown above, the onely run with that figure?
How dit you tune it(feul managment?) |
Re: Power issues
If you dropped oil pressure I would pull the motor or at least pull it apart and find out why.

Re: Power issues
yup,
and running it at 14psi, did you start with 14psi at once or did you build it up from 0 psi to 14? |
