[question] I Have Just Installed A Split Dump Pipe, And My Engine Bay Seems To Be Running Hotter Than Usual

[seven]

Hi all,

My apologies if this has already been posted, but i failed to find it in a search.

I've just had a split dump pipe (Flying Performance) installed today by my dad (thanks dad!) and myself.

One thing that seems mildly concerning is it seems as though after a 45 minute drive, the engine bay is hotter than usual- particularly the area close to the turbo.

I've got a Series 2 R33 GTS-T. The only other mods are the $22 boost controller (dialed in at approx 9 PSI), Catco 3" hi-flow cat (came with car), 3" catback exhaust.

It doesn't appear that any coolant levels have dropped, and performance is fantastic (much smoother power delivery and rev's)- i'm just concerned about the temperature.

The stock temperature guage didn't go any higher than just about the middle.

Any help would be appreciated!

Thanks!

Some exhaust wrap around the split dump especially near the turbo outlet should bring the temps down

its probs a thinner material and/or not as good at holding the heat in compared to the standard steel ones, therefore will let out more heat...

spot on

Does anyone see a problem with running heat wrap on the dump??

Thanks guys- will do!

I probably won't get a chance till next weekend, so just in the meantime- is running it as it is now detrimental or unsafe? Either for the car, performance or the engine?

Quite fine to run it like that mate, i was running a s/s manifold and dump off my s15 a while ago for over a year.

Heat wrap is the best idea but you already put the pipe on so would be a bit of a bugger to remove it again but ohhhh well, you gotta do what you gotta do!

???? keeping more heat in with wrap may increase the chance of s/s cracking; especially with poor quality welding and grade.

Anyone have experience with this?
