VTEC doesn't like boost
So what's the deal with this, is my turbine wheel too small? I have a t3/t4 with an ar of .48 on the turbine and a .6 on the compressor. When VTEC hits it feels pretty bad and almost like it's reached its limit. Anyway, I"m running a JRSC fmu which is like a 5:1 but I've tapped it into the intake manifold so I'll get an extra 5 -10 psi of fuel pressure depending on my IC drop and it's running full rich. I'm just wondering why it feels so flat when VTEC comes on as well as why it sometimes stutters and sputters when giving it full throttle. I'm also running an bosch inline and my stock 310-345 (too many people have said different things) injectors and it's a 94 lude.

Re:VTEC doesn't like boost
Do you have adjustable cam gears?
have you tried playing with them at all? can you adjust your fmu so its maxed out? do you have a a/f gauge or anything to see whats kinda happening when vtec is kicking in? what rpm if vtec working at? do you have a vtec controller? try setting it at the stock location, or even higher. Jeff |
Re:VTEC doesn't like boost
Sounds like your running out of fuel when vtec kicks on.
