Which single mod gives biggest improvement ?

[Craigus]

Turbo

£ vs performance: Definitely stripping! Its FREE!!

But seriously, RSTuner. I borrowed a mates, so only cost me £42 for the code, bargain!

Was gonna say get a exhaust plus de cat. Alot lighter, better looking better sound and power gains and better made. Most positives ya can get from a modification.

Saw one of these this morning, God they look good!

ADD TO CART!!

that'll improve it!!

Anyone got a link to this RS Tuner thing? Ive never heard of it before! Is it a new ecu? or a update for the standard one?
:S

182 manifold, cant wait to get another for my ph1

Presume you mean Inlet manifold/plenum ?

He means exhaust manifold mate. I remember Martin saying how impressed he was with it. Others say there isnt much difference, I can't give an opinion as i've not tried a 182 manifold.

Interesting, I honestly didnt know there was a difference with the Exhaust mani. Maybe worth looking into.

Brakes?

 

[Will.]

CS sticker. A few quid and it adds 10bhp

 

[badgerbite]

You make a back up before you re-write, so if it goes wrong, just restore (Like an iPhone)

You cant go wrong really.

No power loss no

In regards to MOT - does retuning the ECU give higher emissions? If it does, I suppose you just change it back to standard to pass?

 

[DanFreemanPhoto]

Brakes?

For track use yes, for road use it's not essential.

 

[Guvna!]

So the extra 10bhp on the 182 comes from the manifold itself or manifold and exhaust system?

 

[Tom@JMS]

Its PS not bhp

Cat, Manifold, 'RS' inlets, ECU software & cal, just to name a few.

Nope, totally fine for MOT.

172's have 4-1 mani, 182's have 4-2-1 mani. I have a graph of how a 182 mani effects a 172 when fitted with a before and after somewhere - I'll try and dig it out.

 

[Guvna!]

So basically the best mod on a 172 is a 182 manifold and high flow cat/adapter for a 172 system?

learning how to drive it

+ 1 million.

Tuning is completely pointless when you cant get 100% out of the car you already have. Tuition = speed.

From what i've seen the matched inlets give a rather nice gain, but then so does the RS Tuner and/or the V6 Airbox.

I'd be very interested to see this



As for the OP

Ive ran just a de-cat on my ph1 for quite some time, I did see improvements, Since fitting a BTB cat back exhaust with it, Ive noticed now its carbon'd up its pulling very well

For a performance comparison, with the exhaust on its as fast as it was with rear fully stripped and 1 bucket seat, no passenger seat


As for £ per smiles, get a Whiteline Rear ARB, totally transform the car and the best £150 I ever spent on it, much better than more power, more stability gives me much more confidence when steaming into a corner

in my opinion yes assuming you can fit it yourself, wouldnt pay to have it done.

 

[Guvna!]

Isn't it a bit of a sod though putting the cat back on if you have a 182 manifold and 172 system?

K-tec do a link-pipe so it matches up to the same length the original 172 manifold and cat would've met the centre pipe

Is that not a decat pipe though?

 

[Cup_Phil]

It's interesting how all this "biggest improvement" talk is about more power

I find the 172 has ample power - but the handling is not great
Surely being able to put the standard power down is a first before trying to get more

So far for me the whiteline ARB kit on the rear has been the best mod - it has much less understeer and is much more planted on corners

 

[Alan]

CS sticker.

 

[jon_r]

I'd say a membership to this forum where you can all talk about spending £hundreds for 1bhp gains

 

[Guvna!]

Getting power down can be a problem in the 172.

Best way of reducing torque steer and wheel spin off the blocks?

 

[Craigus]

Torque steer? Lol, learn to pull away properly?

Put your back seats down, that helps

i find the opposite, it handles fine for fast road use and the standard setup can take the extra power.

Something anyone hasnt mentioned:

Aftermarket steering wheel. Car was so much more fun when you dont have the standard ship wheel in front of you!
