Looking for a little help on this. I have a JRSC@9psi and at WOT it just bogs down. Actually anything above about 70% throttle! You can hear the blower screaming and I have full boost, just no go! WTF. Anyone experience this, or anything similar? Any help is appreciated thanks.

Whats your fuel doing? Do you have a gauge? Install any new fuel pump lately, injectors, adjust fuel pressure?

My frinend had the same thing on a S/C he had to have it rebuilt. Because it was worn out

My fuel guage is screwy (bad ground I think) and I don't trust it much anyways. But the plugs read good. And the boost guage reads full boost, it even pulls hard up to about 4-5lbs. just under WOT throttle it seems to bog, severely! Getting good fuel pressure also. exciv2000, didn't you have a similar problem a while back?

Ignition? What do your plugs look like? Have you swapped plug wires lately?

If you have a VAFC or the Jackson MAP controller check your connections. Mine had a similar problem, but it was intermittant. Turns out the MAP sensor wire was a little loose and when it would lose contact the car would go full rich and just die at the top end.

a little more info would help here..
do you have an af gauge?
and what does it read when this is happening?
what kind of mods do you have(all of them)
what altitude are you at?
every little bit helps(especially if one cant drive the car themselves..me)

yeah, what newt2 said, except mine was that I had the V-AFC and map controller running in parallel with each other when they should have been in series. does that make sense? All that did tho was throw a code 13 barometer, and I haven't see it since.

I just got a cartech and am looking to get that installed soon so that I don't run so rich up high in the rpms... need to get a new brass nipple for it and some advice from gvtec before I really put it in.

What is your plug gap like? I think mine is right around .030 as should yours be if you're boosting 9 PSI. The harder it is to spark, the more bog you will have. What's your timing set at? What other mods?
