Tell Me Turbo

Well I tried blocking the flow of gasses to the filter off from the port with sheet metal, not the port itself.... looks like I'm gonna have to go make a trip to get a wg dump welded on and then I'll get back to you guys.

what fuel pump are u using with those 450s?

the stock fuel pump WILL crap out.
also do you have a wideband and what fuel management are you using? maybe your timing falls off way too much; that will kill power.

and i dont think your motor will outbreath a t3 turbo.
dodge put .42/.48 t3's on their 2.2/2.5l engines that can make over 300hp with the stock turbo. it moves a lot more aire than even a b-series.

You thiink the dodge engine moves more air then a b-series with vtec head?? the dodge doesn't redline at 8K.
I think it may be your exhaust...using stock exhaust?
I had the same problem..with a D-series hooked up stock exhaust and the car just died at 6K
everytime just went to a dead stop like you mensioned.
Ride with open downpipe or get at least a 2.5" exhaust...the turbo should be ok till 7K on the b-series it will eventually die after that, but will just feel like NA

Tell Me Turbo

Hmm, well honestly guys the more I think about it Im really leaning towards it being the intake sucking in the exhaust gas from the open wastegate because think about it, it only happens at full boost when I hear the wg open, its a very sublime feeling of not wanting to rev higher....different then running lean or rich or pinging etc... Also my wg port points directly at my filter only about 6 inches away.
I'll put a dump tube on it and report back to you guys.

To your posts:

I am using the stock pump but my underhood fuel pressure guage reads ~35 psi at idle so I hope Im ok there. The exhaust is a 2.5 custom straight through. I said above Im using the vafc hack garbage. Also my turbine is a .63/.48 so I know it flows enough cfm's.

You sure you just arent running REALLY rich there?

Try leaning it out slighty and see what happens...

Tell Me Turbo

Well I'm running -34% at 6,000 rpm past like Turboef recommends in the faq, so it shouldn't be too rich to the point I can't accelerate....but who knows....maybe I have a stuck injector or something.

I think at -34% there is too much fuel. Change your settings to -36 from 6000rpm to redline on both the wideband HVT and the narrowband HVT. Test the car and if needs be, gradually lower the amount of fuel.

My car did that at 1psi for a while.

My A/F gauge was reading "lean lean lean" all the time ( although it still cycled at idle ), so I added a fuel pump, still the same problem. So I added an AFPR and turned the presure up some, but that didn't fix it ( all the while the A/F gauge kept reading "LEAN" ). Finally I posted and asked for help and a few people to lean it out a little, and I was like "no way !!! I don't wanna blow my car up, and if its running too rich its not gonna blow-up". Finally I got desprate and turned the AFC setting down to lean it out a little. First run the car hauled ***.

Its scary to lean a car with on wideband out, but my car still runs rich, and the damn A/F is a POS. The A/F still says "lean lean lean", yet my plugs need cleaned about once every week b/c they are so black...

I'd say try -40 AT LEAST.

Also... a .48 turbine isn't going to choke the exhuast off so bad it won't rev to its redline ( power will fall off, but not competely stop it from gaining rpms ). If it was a RBH25 or something, I'd " maybe ".

The honda prob. does flow more than the dodge motor for 2 reasons.
#1 the dodge cyl. head isn't a "crossflow" deisgn.
#2 the honda does turn another 2K Rpms more.
Not to take anything away from that "hammerdog" torque monster.

thats bullshit the stock pump will work fine with those injecters.

im with the afc settings being the problem.

list them all, lo/hi % and all fuel trim settings.
