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


Recommended Posts

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!

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

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?

    • Good to hear. Hopefully you're happy enough not to notice when driving and just enjoy yourself.
    • I mean, most of us just love cars. Doesnt necessarily have to be a skyline.
    • Did you pick up a manual cluster to remove the position indicator?  (Pretty sure the 34 has the gear position in the cluster, but it's been a while)
    • Here is a recipe. Sonic blocks till you get one that has a good enough bore. Get a torque plate and block brace, use your choice of fasteners (arp ect) bolt the thing together empty, half fill it and let it cure. Release it when it has, go to a REPUTABLE RB Builder and get the thing line bored/honed and cylinder honed to size, then wash. Once its all clean and dandy, wash and blow it out again. Then again.  Assemble said engine to your desired clearances with oil control mods, gasket to suit desired CR/Squish ect. Attach your extended sump with proper trap door oil baffles and head drain plumbed to sump with a SUMP BREATHER SYSTEM. Build your front diff with a decent LSD, rebuild your transfer case with a few extra plates, more than likely replace your tailshaft centre bearing and tighten up the rear diff. Tune to minimise excessive midrange cylinder pressure (timing unless you like to split bores and rebuild engines) Enjoy your engine, but hate the fact you are now destroying engine mounts, gearboxes, gearbox mounts, diff output flanges and driveshafts, diff mounts, tailshafts and front CV's.   Disclaimer.... Ive never done any of the aforementioned stuff.......
    • 440s will support well over 400HP on petrol, which is a decent place to be for an RB20. 230+rwkW. Will be a safer bet for idle/low load. 550s would be nice for the extra headroom. I've made the same decision with mine (Neo25). 1000s are probably too big for the Nistuned ECU, so I have some smaller ones.
