I hate to ask such vague questions...but is it possible to predict a ball park power increase/money ratio when tuning a TT ZX?

 

If you were to spend, say £1k, what kind of power would you be looking at?

 

Likewise with £2k?

 

I'm just curious, as it would be some time before I can even afford a Zed...let alone to tune one up :D

a grand wont get you alot but you will get a nice power increase,if you buy the folowing mods

exhaust&decat £600

boost controller approx£250

induction kit£100 approx

chip£100 approx

underdrive puley £150

 

before you do all the following,make sure the car is running sweet,and in good shape,its very hard to predict a power increase with a car 12-15 years old iv seen many differant readings some find an increase of upto 60hp some 30hp so it depends on car,engine health etc

 

when modding any car for more power,your also putting more strain on old components so maxing out stock turbos will eventually kill them sooner,so you pay your money take your chance,im going to take my chance :rolleyes:

That seems like a fair amount of kit for the cash :)

 

I've heard the advice of making sure the car is sweet before. Makes a lot of sense!

 

I know my profile says Mids...but my term-time home isn't far from the WSM :D

hi Rob. what greg has outlined above demonstrates very good value (or power ;) ) per £. however once you've reached that stage (and running about 360-380bhp at the fly) you'll probably need to fork out a good 2.5k+ for uprated turbos and intercoolers. from then on you're flying again (almost literally :D ) - just dial in higher boost from the controller you've already got.

The correct answer to your question is "no". :D It is not possible to predict a ball park power increase when tuning a TT ZX.

 

Where are you starting from? A standard unmodded or a Zed with a few well-done mods or a one which has been through the hands of modding f*ckwits?

 

Given that you already have a car which cost over £38,000 a decade ago and which has 280 (or 300) stated fwhp, why does anyone believe spending a few quid on Max Power w*nk will do anything other than f*ck it up?

fwhp :smash:

 

doubt there is many on this forum in to max power LOL,i can see what your saying though there is to many people ruining there cars for extra power,but if modded sensibly,whatever that is then you are less likely to **** it up,but more chance of increasing the chance of doing so. :smash:

I certainly had nothing even slightly related to Max Power in mind :tongue:

 

I'm just curious as to what kind of tuning potential the Zed has, regarding tweaking a bit more power out of them

fly wheel :cool:

It has a lot of potential but only if you really really know what you're doing (eg MAC1, Z-Tech etc). If you have just bought a Zed, £1,000 or £2,000 will be far better spent in fixing what needs fixing than bolting more (and mostly badly thought out) mods onto a tired motor.

 

EG: cambelt, engine wiring loom (connectors at the very least), suspension bushes, maybe springs, full 4-wheel tracking, throttle body clean, PCVs, etc etc. Then if you've still got some dosh left over, go on a track day and a high-speed driving course and you and your Zed will be significantly faster and safer and more reliable and more fun to drive every day.

 

And since you can't wave a stick round here without finding reasons why mods are good, here is a completely biased Luddite view:

 

stainless exhaust = good. Longer lasting and cheaper than the OEM rust bucket.

decat = kills off your turbos more quickly through not enough back pressure on the worn seals. Even if your turbos were perfect, decat increases wear and decreases life.

boost controller = potential trouble. Increasing boost increases load on worn system all round and makes other failures more likely.

induction kit = filter problems or added filter maintenance or lets water in to screw up your MAF = expensive

chip = which one? Who can tell the difference between a good chip mapped safely for UK fuel and one based on US or JDM? The road to detonation (especially when combined with boost controller) and expensive bangs.

 

And another thing, you get increased insurance costs & some insurance companies are not mod-friendly.

And another thing, even if you do get 15 or 30 rwhp extra, to what end? When and where will you actually notice the difference?

my car has all the above from gregs list

(apart from pulley)

its uk with 150k on the clock

it runs 357.5 bhp at 13psi fwhp

if thats any use

Exactly what make of parts are you running, ie chip, ind kit? Thanks.

mines chip

apexi filter

profec b boost controller

mongoose s/s with decat

A very informative read Gio :)

 

As I said, it's not like I own and Z and am about to go blow some cash on it...your advice is certainly very valuable from a common sense point of view!

 

Chips: surely with decent research from forums like this (and other source) before hand it would be possible to find a decent UK specced on?

 

And should a decent induction kit not let in water?

Well I am getting on a bit these days cough mnk.

 

Not having experienced either, I am no expert but yes I would have thought a decent induction kit wouldn't let in water. However, if you search through here you will find a lot of owners who have fitted a kit from a reputable brand and found that, yep, it lets in water.

 

Chips: if you ask 5 Zed owners, you'll get 6 answers! The difficulty is separating the bull from those who've swallowed the bull from those who really know what they're on about. :D

i think after i get me car back and run her in , a rolling road session is in order !!

I think that the majority of wet MAF problems are down to lack of splashguard or leaking/vented headlight panels. Never had any water near my filters..

MAC_s Power? :p:x:

That makes sense...

Isn't there some other question about having to oil / clean / not clean certain types of filter?

IMHO he's doing a proper job. That's streets away from the "shopping list approach" of just bunging on what "everyone says" onto an old nail and hoping to get 1000hp! :D

That makes sense...

That's right Gio - "wet" or "oiled" filters can suffer from over oiling contaminating the MAF. Dry filter won't have this problem.

Ta. Makes sense yet again!

 

Oh and while I'm here, another post has reminded me of a mod which IMNVHO makes a lot of sense: traction control. Properly installed and set up, this can be a great safety aid.

Listen to GIO, sometimes you need someone to ground you :D, its very easy to get carried away with these cars and end up with a 2 grand bill for something you end up swapping out at a later date.

 

I mod my car quite slowly, but i do not regret any mod i've done or any money i've spent because I have researched and thought out every one of them, its very easy to get carried away with chipping and boosting these cars and you just end up with a very heavy paperweight (and im not talking about danny's offering)

 

Personally i think the route to go is,

 

Induction - Exhaust

 

Sort out your handling next, suspension brake, traction control maybe,

 

clutch / flywheel

 

Chip and raised boost

 

Then enjoy that speed for a while, then you can start faffing around with turbos, pistons, 1 pluck 2 pluck 3 pluck more clutches, fuel management, snakeoil

 

Of course body work and bling and all that nonsense can be added at anytime ;) it won't improve your performance.

 

I have a list of stuff i want to buy to rebuild the engine to make it faster, but then i go out in her, she drives like a dream and the rear wheels light up in 1st and 2nd gear

 

of course is something breaks you always put something bigger better and stronger in its place :D

 

 

and all this like GIO says after you have a sound stock motor.

 

Rolling roads are good to know how you've improved performance wise, and the likes of thor are known to be wizards in the tweaking stakes, but there is relatively little sense in sticking your car on week in and week out if nothing has changed/you have no problems

to ground you :

 

Yep, one of them too :D

I think I would have to pass on a grounding kit - car audio happens to be a little obsession of mine, so I'm pretty accustomed to fiddling with cables and such like :D

not sure if your getting mixed up with suppressors etc

the grounding kit is just a tiny bit related to audio

if you already know ignore me lol

Not at all - to me, a grounding kit just looks like upgrading the wires in the engine bay. When installing a decent stereo, you can have 0awg engine earths/batt + to alt + etc to improve current flow
