B16A1 in my poor 91 teg
 

I have a question that i think i know the answer but i jsut want some imput. Here is what happening, If i got to redline the B16A i start off and im fine till about 6k then tis starts loosing its strength and then at 7500 RPM its pratically a dead stop, it just wont go any more. Im thinking my fuel pump is going to ---- and i have one on the way but i jsut want some imput. (no i dont have a fuel gague and everythign is stock, no modification. Its odd be it really slows down after 7k RPM and just sits at 7500 RPM kinda like you are going into the mountains or its not gettign enought air/fuel. Yes, the air cleaner has been changed;).

Is it switching to the high speed cam? Sounds like its wheezing out on the low-speeds.
Does it miss or pop? or just run outa steam?

If you go lean anough quick enough, it doesn't wheeze or pop.

I have a friend who was trying to FMU @ 5 psi a B18A CRX HF... You'd hit boost, and watch the AF gauge go steadily lean; never hear detonation and never see any extra power. If she's lean enough, you don't detonate - I think past 17:1 is when fuel/air doesn't like to ignite.

You can diagnose it with either AF gauge, fuel pressure gauge, or DVOM hooked to O2 wire.

it switches to VTEC fine and what not i have put my VAFC to it and tried to add fuel or drop fuel to no diffrence. i dont have an A/F gauge yet or anyhting but its jsut odd how its doing this. VTEC is solid when it goes in at 5500 RPM but after 6k RPM it dwendles off. if i have it sitting there and rev it it goes strong untill i hit hte gas cutoff at 7200 RPM (at idle with no load).
