strange noise

Over the last couple of weeks my car has started making a weird kind of creaking/groaning noise coming from the front left, it pretty much stops if you brake but the brakes aren't binding. It's definitely something that's turning as it's not a constant noise but increases as you get faster. Doesn't stop if you dip the clutch, could be wheel bearing, cv joint or maybe coming from the gearbox. Just after any other suggestions before I have a proper look. :-D

cheers

are you running standard calipers? if not the noise could be your pads moving in calipers i used to get the noise on my old ap's

No I have hi-spec 4 pots. I had thought of that and they do rattle and click a bit but to make this noise they would have to be seized on quite hard which they aren't.

HKS downpipe - I didn't know they did a 3" one? The mongoose downpipe was always recommended over the HKS one as the HKS one is mild steel (allegedly) and rusts to death.

Get the samco hoses kits for the back of the engine if you don't already have them.

That's what I was hinting at. I thought it was pretty much the same as the goose except the goose is stainless isn't it?

Ditch the uprated leads and stick with new standard Nissan items.

As already mentioned, ACL race bearing, new oil and water pump, tentionsor, timing chain and followers and water hoses on the back of the block. While the engine is out get the starter motor overhalled and get the idel control valve cleaned out.

If your not after big horse power then you will not need uprated rod. For what they cost I would deffo get ARP rod bolts.

Another area usually overlooked is brakes and suspenion.

Torque V’s BHP

I’m curious to understand Torque over BHP?

Looking at my previous results and other car readouts I’m curious how some results come back as 450bhp and yet have results of 370lbft? Yet on some other hillclimb cars they can be 300bhp and 380lbft – iirc WRC cars are 300bhp and 700lbft!!! :thumb:

I’m not getting hung up on any results as I take them with a pinch of salt, but I wondered how you could raise your torque levels? Is it dependant on modifications; clearly easy breathing is obvious, but what else can raise torque levels? Is it a mapping thing or simply boosting the thing to death?

Any kind of relevant information would be appreciated and interesting to read ;-)

point 3.2 here also mentions about reducing the lag on the car by recirculating some of the air:
