Hello All,

I currently have a noobtune stage 1 ECU and as seems to happen, I am considering more power. I have 3 questions:

1. Does the stage 3 downpipe(from APH performance) on a standard exhaust increase the noise of the car?

2. How long would it take to fit the full downpipe? I would be paying a local garage or exhaust place to do the work. I am also aware I would need uprated fuel injectors and a new upgrade from noobtune.

3. Is there a local, reliable SAAB specialist in Newcastle upon Tyne

Many thanks

Paul

1. Not really noticeable.

2. I'd expect less than an hour. Crusty rusty nuts not getting in the way. You can happily run it like that too. I did for several months before moving to stage 3. It's more responsive as a bonus.

3. Can't help on that, sorry. Though I did know a place called the Stage Door that I've misspent time in.

Thanks for the answers DeeDub8.


I know the Stage door, however it was never one of my regular haunts. I preferred/prefer the seedier real ale houses of Newcastle :shock:

The downpipe will make it a bit noisier (in a nice way) when under boost, but that's about it - when cruising there's not really any difference.

If you're getting a map from noobtune, you can just fit an uprated fuel pressure regulator (3.5 Bar) instead of bigger injectors. However, if you then want to go past stage 3 you'd need to swap the FPR back and go for bigger injectors anyway. Personally, I'm at stage 3 with the uprated FPR as I have no intention of going any further ...

I got my DP from PFS, it's cheaper and does the job.

I also went for the 3.5 bar FPR.

Now I also have this on order...

Sounds - thanks for the advice. I don't want a noisy car, I just want a faster car, especially in a straight line. I will almost certainly go for the Stage 3 route and see how it feels. noobtune did my stage 1 ECU and the difference in torque was incredible :D .

RocketScientist - I may go for the PFS downpipe as I believe they are readily available. I have considered the intercooler also, however the price for the extra power seems quite high, what performance difference will it make to my car, or will it make it more reliable?

Many thanks all.

Paul

I would actually suggest that an uprated Intercooler should be a definite at stage 1 let alone stage 3.

It will make a difference to performance, especially on warmer days, and also to the ability for repeated pulls without loss in performance.
A bigger cooler also adds a bigger safety margin against det.

There is an argument to be made that the cost vs gains don't justify the expense (an extra 10BHP and 10 Nm) - on paper. But if you factor in the improvement in how the engine breathes and responds (plus what Rich said above) then it can be regarded as a sound investment. Personally I just got a bot carried away one evening and ordered the darn thing...

All the best

Kiwi

Second vote for bigger I/c - it does make a difference - seems to breathe a lot better.

Gents, I am detecting a lot of pressure to go for stage 3+ :wink: . I am waiting to see if I change my job in the next week. If so my mileage will drop and I will go to stage3+

PS How long does it take to change the intercooler?

Many thanks

Paul

For a first time go, probably about 3 hours or so.
It gets easier with practice.

I would start putting penetrating oil on the nuts which hold the rad stack support brackets to the subframe now.

Doug (cardboardcutout) and I are planning to do this on Saturday, so will let you know how it goes, and if any issues. Other jobs to do that day are: -

Replace wiper stalk
Replace near side wheel arch liner
Replace WGA (if there is time)
Replace DV (maybe)
Swap ECU (obviously)

Going to be a busy day :-)

People always forget about cooling. Not the same car but my Toyota Celica GT-Four the first modifications I did was add a header tank/swirlpot to the cooling system and lag the charge cooler with heat reflective tape. Then I started with the usual down pipe, exhaust, hybrid turbo, going down the rabbit hole scenario :D .

Apologies for the ultra-noob question but am I right in thinking you're planning the 3" DP but with a standard exhaust system?

I'm 100% standard (9-5 Aero) at the moment and would like a "little more" so am just trying to get my head around things as much as possible. My last modified car was a Supra and things seem fairly similar in that it's getting the air in and out efficiently and adding some boost to begin with, I just want to try and avoid the inevitable rabbit hole if I can and spend the money on things I need rather than things I think I need.

The exhaust system for petrol 9-5s is the same for them all. The differences being the back box - single/twin pipes. You can also use the diesel parts from the cat-back. Diesel back boxes have been used by folk on here on non std setups. There may be some inaccuracies in that but in the main it's correct.

The other good news is the std exhaust from the cat-back* is not a restriction until you're past 350bhp or so. Mating q 3" downpipe and sports cat to the rest works well.

If you plan on bigger numbers a fatter exhaust will one of the least expensive items on the list.

*I know it's not a bit but a description.
