exhaust glows red!!??

[boofa]

Hey everyone, any input will greatly be appreciated.

Setup: S13 Blacktop in 98 Kouki
Stock ECU
SR MAF
550 Injectors Top Feed
Sard Fuel Pressure Regulator w/ B&M Gauge
3" Downpipe
3" Exhaust
Stock Turbo
FMIC
everything else is pretty much stock...

Issue: Before I put on my exhaust... the engine revved freely and strong = but I did experience some back fire... ?? even without an exhaust...

Problem: Now that I have an exhaust with 3" high flo cat... The car does not rev past 3-4k while in gear... when I'm not in gear the car can still rev... but it's slower... and so while I'm moving... there's like... no power. There is substantial backfire.. and when I do get to rev around 3-4k, it sounds like I hit a rev limitter... It just doesn't go past it.

Current: So after I drive it back from the exhaust shop. I look at the muffler, and I can see the inside glowing red. I have never seen the exhaust glo before, and I don't think that's a very good sign.

Troubleshooting: I lowered the psi on the FPR (fuel pressure regulator) to 35, [it was set at 40 before] - and it still had problems. I did this because the exhaust shop mech suggested that it was running rich. But who knows?

Other than that - I don't know what to do...

Questions:

1. Am I running Rich or Lean?
2. What can I do right now to fix this issue?
3. Is there a way without buying more expensive parts?
4. If the only way is to buy more stuff [ie: chip, wideband, etc] - what exactly do I need?
5. Is there anyone in the area that is willing to help me out in person? (Location: Northern New Jersey, Bergen County)

Thanks guys/girls - I look forward to your replies.

Sam.

Running to rich doesnt cause the exhaust to glow, its actually normal for a boosted car to glow red during extended periods of boosting. Running rich will run a bit cooler then a lean running car.Did you get your car properly tuned for your injectors and stuff?

make sure your oil pressure is good. no cooling of the turbine = really really hot. had for the motor to even rev that high. not to mention you are eating your bearings away. CAS mamby, timing. I speak from experience http://a416.ac-images.myspacecdn.com/images01/44/l_4c4324677151332f2693eed2bbbe3b5f.jpg

What about your timing?

[Kaldar142]

is your BOV recirculated?

that my friend has nothignt o do with it. U fail

I ask backfire because when the timing was off a bit on my RX-7, it backfired like HELL and had trouble firing to get the RPMs up quickly like it should have.

Id say check your timing, or maybe the type of plugs you use as well?

[boofa]

it's strange tho - because my key argument is that the car could rev freely without an exhaust.. although it backfired a bit.... NOW - with an exhaust.. it does not rev above 4k while in gear... =T

[kawika219]

maybe the shop messed with something

[boofa]

oh - and the car wasn't boosting at all - and the car was running for only 15-20 minutes... basically.. moving the car from the exhaust shop to my garage.

Check to see if anything in stuck in the exhaust system.

Do you have a catalytic converter still?

[LB.Motoring]

your exhuast glows red becouse there are little devils in your cyclinders

[Ameerov]

you need to getthe car tuned for the fuel delivery and timing set so it will rev up to redline.

[chibo]

That'd be your timing way off.

check fpr and timing. also sounds like you're running alittle lean. get a EGT and see where you're at.
