Thread: Testing performance mods - no change?

none of your 4 mods are performance mods.

3 of them are extend life time/ prevent future failure mods (EGR, MAF, silicone hoses)

the last is a **** mod to let it make more noise unless you do other mods later on. (the OEM center muffler flows better than the rest of the exhaust until you up the exhaust size and/or remap the engine)

Wow. Ok, I guess I have to agree with you given that's what I've experienced so far. I'm surprised that so many others are also fooled into thinking these changes have something to do with performance, and I don't recall seeing that the centre muffler was not one of the limiting factors in air flow. At this point I'm guessing that de-cat (not an issue for me as I don't have one in any case) and larger intercooler aren't particularly helpful either.

What would be considered a performance mod other than a remap?

The centre muffler removal is allegedly for helping to turbo spool up faster in order to reduce lag.

Get onto TRS in Adelaide ... for around $650 exchange, you'll get the performance you're after.

A bigger intercooler will also help with your EGTs.

Tweak your your waste gate.

Appears you have access to a nanocom so hook it up and adjust boost to 19 psi ( just below cutoff at 20 psi).

Do a search on here, lotsa posts, info etc.

Then fit the bigger I/C .

Doing that definitely improves performance, and its cheapo!

I did mine and love the result.

Larger intercooler is a performance mod. So is an egr kit. The egr siphons off exhaust gas an recirculates it into the inlet. This means some boost is lost. It also means some unclean hot air into your intake. This WILL detract from performance. Getting rid of the egr with a kit means all exhaust gas is now for boost and only cool intake clean air is going into intake. This means better combustion.
Don't get me wrong, the impact is not earth shattering and you won't notice the difference in your test distance to 100kph, but it would be noticed on a dyno.

The larger intercooler will also be a good improvement because the intake air will be more effectively cooled so therefore a denser volume into the cylinder means more power developed. It has other benefits like the egt as well.

All these things are steps in a whole process and their maximum benefit is only realised when the whole kit and caboodle is done, chipping, exhaust, etc etc.
an upgraded ecu or reflash on the later ecu is the best and most obvious upgrade and you WILL notice that!

larger diameter+/or mandrel bent exhaust, larger intercooler, stroke the cranke oversize the bores, replace the pistons for different compressor, different turbo, fitting a lies box between the engine and the ECU,

If you expand your definition of performance to encompass the whole vehicle and not just the engines peak power/torque figures theres a whole scope more.

If doing the 4 mods that you've already done increases the performance of your vehicle what you've achieved is a percieved gain from a degraded state to the factory state. (but in doing the mods you may be in violation of some legislation somewhere)

Hey, owning a Land Rover is in violation of some legislation somewhere , just ask a toysan owner

errrr, no, under full power conditions the EGR if working properly should be fully closed.

The EGR (on a diesel) opens to displace some of the o2 in the intake during periods when the power request is such that the amount of diesel being injected is not enough to use up all the available o2, this reduces oxides of nitrogen.

Essentially the only time the EGR opens is when you are not requesting full power and if you're not requesting full power then it doesnt matter if the EGR is open or not (from a power perspective).
