I was talking to some buddies of mine that run DSMs, and those guys are running 1550 or so though the traps(EGT) with built 4G63s that are dyno tuned. I thought that was a little excessive, but that engine uses a cast iron block and a different design than most Hondas, any Honda guys running that hot?

 

I think the most I have ever hit was 1400, but mine is after the turbo in the downpipe. That is also not on a track, just beating the hell out of it.

 

i hit 1400 too, like when im flooring it on teh freeway and such.....

my probe is also in the downpipe of my header, i have a JRSC

 

I hit 700 degrees Celsius just cruising on the freeway. My probe is also on the downpipe.
