Well I finally finished my Turbo upgrade with a t04e , my motor is street ported and is running with the stock intercoler and an HKS Fcon for temp. fuel inrichment/management and after a running my car and pushing it at 10lb for a few mins i looked that the turbo and the exhaust housing was glowing.. any ideas suggestions??

 

Did you change your fuel filter and upgrade your fuel pump? You could be running out of fuel.

 

Not yet.. but i pretty sure that im not runing out of fuel.. but i need to install me AF meter first.

 

it does that after u drive the crap out of it or you have a clogged exhaust!

 

Dont have a cat to worry about.

 

Do you have a fuel gauge? If not you should get one. It helps out alot when troubleshooting. Chances are if you have the stock pump and dumping alot of fuel you are running out of it also.

 

Whats up, Check your timing...2 times if you already did.

Peace, Justin

 

hmmmmmm, well................nothing is wrong with your car. Your turbo will glow regardless of fuel setup, or even the turbo thats on the car. its completely normal, and happens regardless of how hard you drive the car. it can get that hot cruising, or just lugging around town putting a load on the motor.

now........running 10psi on a To4 with a streetported motor and a STOCK IC is pretty gay

what exactly ARE your complete fuel upgrades ?

 

Well im still waiting for my haltech that I ordered 4 weeks ago... hks fcon, stock injectors, fuel pump, and most other possible mods are done, once i get the haltech i plan to runn 720 cc primaries and 1300cc secondaries.... and installmy 3 row fmic... i have a greddy 3 row Rspl ITC that is for a sylvia, descided to put it on my rx7 instead of my 240..

 

Agreed!

 

when it starts to glow like that, its running lean

 

you need to get an exhaust gas temp gauge. i have a stainless manifold and it gets red at about 500 deg C and is neon red at about 900 deg C which is the perfect a/f

 

oops

 

about 850deg C

 

My exhaust manifold (stainless steel) glows but the turbo itself has never glowed, at least not to my knowledge, not even on a 4th gear dyno pull (long!).

 

Install an Exhaust Gas Temp Gauge (EGT) and you will no for sure if your "Glowing" is getting out of control.

 

Im in the process now... so I'll have some numbers and pix avail. soon.

 

the best postion is in the manifold or exaust housing of the turbine. mine is in the turbine.





about 850deg C 4th gear dyno pull

 

i just bought my first tII and after drivin around i noticed my turbo manifold was glowing red too, and when i floor it in 3rd gear it doesnt respond too well, it lags and then pulls and again over and over untill i have to shift to fourth and it does it in 4th too when flooring it! any suggestions before i take it to the shop

 

While running lean can cause the manifold and or hotside to glow, it is not the only possibility. Timing that is overly retarded can do the same, as well as timing that is overly advanced.

retarded timing will leave too much unburnt fuel in the exhaust stream which will then burn in the manifold, or hotside snail causing them to glow.

Timing that is too far advanced will cause pre-ignition that will also cause them to glow.

Lastly but not least is being to lean which causes elevated temps as mentioned above, although i suspect you would get alean misfire that would be noticeable at upper RPM's.
