Is it just me or does that seem a bit low. I know that around 1250 to 1300 cylinder degrees things start to happen to the pistons, so I would think you'd be safe to at least 1150 on the manifold temp. My pyro is in the center of the collector going into the turbo (welded in bung) and I push mine to 1200 all the time with no problems. I have even seen it spike to over 1400 and I am still just fine. It takes a high temp for an extended period to do damage to the pistons, short spikes usually are non damaging. Might want to ask your tuner to see what he recommends as a top EGT, or did you already and I'm talking out of the top of my hat.:shrug:FIREBALL said:pre......sender in the exhaust manifold.
