Next Little Step For The Tt..

[Grudgee]

I'm currently sitting on 251kw at the wheels, with Phoon CAI + K&N, debunged exhaust and CAPA flash tune.

I don't want to change the stock cooler, as it's a massive pain in the arse and was wondering if my reckoning is on track. I'm planning to swap out the cat with something better flowing (TT's have a 3" remember) as well as swap out the injectors for something recommended by the masses here.

Is there anything else that'll help increase power, whist not touching the cooler setup? I know the intercooler is going to be my limiting factor, but I want to retain this factory setup and get the most out of the vehicle with the factory setup.

Any ideas, guesses, thoughts on the kind of result I could expect from the cat + injector + retune?

Anyone got any idea what kind of results I should expect at the track with the improvement. Ie. is 10kw at the wheels theoretically going to give a X time improvement? Is there a formula to use as a guide?

You can do all of that without touching the cooler but you're not doing your engine any favours by feeding it such high intake temps.

I wouldn't do anymore than you've outlined above without doing the cooler.

Don't do the cooler and you wont get much more power at all. Kinda wasted effort and money on everything else.

Thanks for the replies.

Both valid feedback - albeit feedback I didn't want to hear, as I was hoping I'd be able to stretch out 20-30 more kw at the wheels without touching the intercooler setup.

Oh well, I guess that's the end of the road for the TT's mods for now. I can't justify going too hard, as the Mrs will have the car in a few months and it's pointless/dangerous having her with a monster TT.

I reckon you could get more out of it with injectors and a CAT mate. The cooler won't be extremely repeatable but you will have a safety margin with the bigger injectors and freer flowing CAT

high intake temps mean the air is less dense- not as much fuel gets mixed with the air- not as much exhaust gas is expelled from the engine- less demand is placed on the exhaust system.

you have to get air into the engine before you worry about getting it out

Any clues on where in Sydney is a good place to go to get the sort of mods that Grudgee has done on a TT?

Also, is 250RWKW gonna cause problems with the AWD drivetrain over time?

Cheers,

TT with a HUGE frontmount :ladysman:

If I wasn't getting married in December, I'd already have one! If I ditch the wedding I'll have over $30k to throw at the Terry.

If you dontwant to replace your cooler why dont you fit water/meth injection as well as the mods you listed.
