What did you do to your Polo today?

[fuzion]

Its not just about boost. MBC can add boost, but if the ECU is confused by the extra boost, it can pull timing, bleed it off, etc.

Whilst boost is an important aspect of our cars, its not everything... The difference from 17-21 psi may only be a few KW, but I prefer to look at the Torque curve than anything else...

Seems pretty obvisous by now that Giac'd Polo's are pulling slightly better numbers than APR's...

Thunder, you are likely getting more peak PSI, when I was using an MBC I found that boost came on quick, torque was hard, but it also died lower in the rev range. Ultimartely, if you are getting more peak torque but the rest of the curve is suffering, you are prefering peak torque and more noise over a more consistant curve.

when I was logging a lot, I found the best results came from timing and bypassing the N249, the MBC didn't do it for me. Nor did the J vesion of the N75. As Fuzion has said, what works for one tune or vehcile may not work the same on the next.

If you are chasing the last few KW with the existing tune you can also try:
- changing the intake (eg POD)
- removing grills on the MAF
- phelonic spacer (more about heat)
- porting / polishing the exhaust manifold
- better flowing intake mani
- decat / gutted cat / sports cat
- cams / block work
- injectors / fuel reg / fuel pump
- full exhaust
- cranking the turbo waste gate
- intercooer
- Tip / boost piping flow

At the end of the day, it would seem the stock turbo and tune make the biggest impact. K03 can do good things, but a hybrid turbo and good tune is a different ballgame without going to a garrett and a bunch of custom work.

I wouldnt particularly agree, but each have their own theory.

After 3 week, 4 new tyres, 3 replaced windscreens, failed attempt at replacing my springs and consequently ending up having to pay to get it done (yes I know I suck), today I finally got the defect notice off my car.... do you think the vic roads guy even came out to look at the car?!... no.

So spent quit a lot of money I didn't have to pretty much put my car to stock (minus window tint and APR) for nothing, could of got a dodgy roadworthy for a 5th of the price and cake walked if they knew weren't going to look the car over!

And before anyone gets into it.. I know, I made the choice to do mods that weren't 100% legal shouldn't bitch when I get busted and I normally wouldn't but the timing was ****... bah I know I deserved it.

What mods did they pick you up on ?

[hazrd]

by the sounds of it.... bald tyres, too low, cracked windscreen (although i cant explain the '3')

unlucky mate... im sure theres a lot of us on here with a few mods the cops wouldnt call "within legal spec" its just a matter of when they bother to look u over

Just wheel poke, didn't want to risk not passing roadworthy with the 17s so went back to the original 16s which all needed new tyre.
They didn't see the chip in the windscreen but I knew the roadworthy mechanic would, 3 windscreen cos O'brians surprisingly don't know how to fit windscreens without ****ing up.
First was fitted all to one side, so like a 2cm gap on one side and none on the other, next they installed a non genuine screen to fix the first **** up, I ordered a genuine screen

And yeah lowering springs where the roadworthy mechanic's call thought it would pass but didn't was like 1cm too short at the centre of the car.
Wouldn’t bother me so much if I managed to change them out myself but I’m retarded and couldn’t get the front struts to budge.

Just took the car for a quick strap... Loving this cooler air down here!! The car is loving it!

[PeterHBne]

How'd they get you in the first place? Did you attract their attention, random pullover or an organised roadside check?

What tyres did you get (I'm looking)?

[PeterHBne]

They are cheap - $137 per corner is good. I rang a dealer today who (as they all always seem to) rubbished these tyres and said they were no longer available here (they once sold them). Most people in the tyre post seem to like them and quite a few have them/tried them...........

[noone]

What are they?
