Mx5 turbo cooling

[lpeck]

Just fitted turbo upgrade on my 91 na. Haven't had a full dyno tune yet but have just been driving it around on stock psi without boosting it and found that the engine bay is getting really hot even after a 3km drive. I have fitted intercooler and alloy radiator.... Thinking about heat wrapping manifold and exhaust. Any other tips would be really helpful. Thanks

What radiator did you use and where did you get it from? I need a new one

It shouldn't get very hot if you aren't using any boost. What engine management system are you using, and if it's an add-on/replacement for the standard ECU, has the ignition timing been set correctly. If the timing is retarded it will send the underbonnet temperatures up big time.

Fenix radiator from fenix nz. Megasquirt ecu timing set at 10 degrees might wait unit ill I get tune and see if temp drops.

if your running base tune itll be rich and retarded . thats gonna put a lot of heat energy into the engine and manifold instead of power. itll get better with a tune.

dont wrap the turbo or manifold. it just promotes cracking. i wrapped my downpipe with exhaust wrap to protect the trans tunnel and gearbox.

wrap the things you dont want to melt. I wrapped my heater hoses, lower radiator hose, and pass side hard brake line.
i also made a cold air box that runs the length of the engine bay that has a heatshield material on it. i also riveted the stuff to the inside of the bonnet just above the turbo to stop it melting the paint on the bonnet and to the pass side of the trans tunnel to stop it melting the carpet. haha seriously it gets damn hot there
