hey peeps just took a slow drive few miles down the road as me and me missus went out for somthing to eat

gave car small birsts of thottle but arf no richer than 14.1 basicly no boost talking it easy ,any way got home and thought check every thing over and noticed right in middle of exh were goes onto turbo was glowing bright red under the heat wrap is this normal?????


just waiting on egt hardware so no idea what egt was but i wasint boosting it through high revs etc

just looks worrying

Which side of the turbo? If before the turbo it would suggest too much back pressure or a restrictive turbo not flowing. If after the turbo it would likely be too lean a mixture.

 

its b4 the turbo basicly at the manifold end before it goes on t3 flange

i did this conversion not thinking of b/pressure i still have std centre box of xr3i and s/s end can seems a bit much prob

i have a tunable b/box in the garage can i remove c/box and put on tunable b/box only due to noise for police theres loads around here


thanks for the reply got a bit worried

Most turbocharged cars manifolds will glow when running around stoich, its not necessarily an issue.

 

It's the bit about only a few miles and not boosting that makes me think something's amiss. Ignition retarded too much?

 

Almost impossible to speculate as you will appreciate Bob, hence i said not "Necessarily" a problem to stop others instantly worrying about their red manifolds.. lol.

Ignition retard is deffo a possibility, as is incorrect turbine housing amongst other thingss, but again, it may be fine... may be time for a pro to look her over.

 

I agree, but I think this engine's on a Megasquirt ecu and therefore the need for a bit more investigation as you say. The heat wrap's probably not helping either.

 

Its on MS?
The plot thickens

 

thanks for input guys is a bit retarded at the min just that my usb-serial converter kept on crashing so had to get pcmcia card the tining is about 13-19 degrees in low down areas

thanks to the 2 of yous for the input
tommy


wt advane yould you roughly run between 40-90 kpa boost cones in around 100 kpa
thanks
