Intake, filter, exhaust, remap - budget and benefits?

[Noodle999]

Hi guys,

Having vowed never to seriously mod the Trophy I've seen that a lot of other people have had some minor stuff done and I feel like doing some non-invasive easily-reversible mods. Basically I think my plan is to get a replacement panel filter (rather than some big noisy induction kit), have the intake matched, fit a Janspeed system and then have it all remapped to see the optimum benefit from it all. Basically the key questions are:

- Which panel filter? I'm not looking for maximum gain due to having something that barely protects the engine, but I don't want to fit something that's just a waste of money. I'm thinking maybe something by ITG from looking at other people's feedback?
- What are people's experiences from having had their intakes matched/polished?
- Is the Janspeed a good choice for someone not wishing to spend the earth? It seems to be quite well reviewed on here.
- When it comes to the remap, is there a specific one that likes the type of mods I'm proposing, rather than going for a more expensive custom remap? (I am aware the custom remap will provide the maximum gain, but I'm trying not to break the bank and I don't want to be stuck to a specific fuel e.g. Optimax or something to avoid the car running badly, as it's not available nearby - I use it 75% of the time but I can't always get it).

Lastly what benefits am I likely to see from this lot realistically, have people who've done similar found it worthwhile, and is it realistic on a budget of say £600?

Any input would be greatly appreciated

ITG panel filter check the forsale section there is a group buy on them.

Angel works do inlet matching around £170 iirc?

remap has to me RSTuning heard good things about them, he is based in Leeds.

so panel filter is £40 say

inlet work around £170

exhaust what £300 - £400

and remap is around the £250 mark?


Perphaps a little over £600...

These mods in my experience don't make a lot of difference, however I'd say if you go ahead, forget the panel and go for a Maxogen. I was impressed with mine in spite of what a 'tuner' on here said about them.

i would go for a panel filter £40 and easily swapped back to oe (plus cheaper than maxogen but if you were after max bhp then that would prob be the best to go for), cant comment on the janspeed as i havnt got one or heard one i went for a btb system but you cant get them anymore, as for the matched inlets as yours is a trophy i dont think you would get many gains, the 172's and early non rs inlet manifold 182's have had some reasonable gains but on your trophy its already an rs inlet so they are meant to be better. i would also say rs tuning would be the best to go for however i think angelworks which is nearer to you do the same maps which he gets of rs tuning (i think)

so basically, panel filter, whichever exhausts system takes your fancy (milltek get good reviews) and then a remap.

The money would be better spent on learning to drive the car - on a track and initially with a race training instructor. I think any power increases from the mods you listed are limited, frankly. That's my view and I wouldn't bother with any of the mods you've listed (although an exhaust might be wise as the std one isn't that good). Hope it helps.

You saw the difference with the ported inlet against yours with mine rob, imo a good mod.

p.s saw you the other day heading towards burnham/weston, i was in the espace, did falsh at you, you looked quite confused!

Don't think for a minute that a panel filter will gain you anything. The only advantage I can see they have over a paper filter is that they don't need replacing so often. Not a mod for power imho.

on my ph1 airbox (i.e the proper one ) i noticed a definete benefit from a K&N panel over the paper crap that was in there previously

 

[Lagerlout]

Placebo effect?

Why is the ph1 airbox the 'proper one'? I had a panel in my ph2 and it made diddly squat difference. Nil. Nada.


And there's nothing wrong with paper filters.

What he said.

i think the ph 1 airbox had just 1 large cold air feed v the 2 smaller ones on the later models (one cold and one luke warm) and some tuners etc try and get hold of these and retro fit them to newer models.

were not saying a £40 filter will make a driveable diff, however if you plan on keeping the car for over 2 years it will earn its keep (just had £15 knocked of my next service becuase i have an aftermarket filter so after 2 services not only has it almost paid for itself but you have enjoyed any gains) but if your after modding your engine and trying to get a few bhp from a 2.0 litre n/a lump then a filter, exhaust and remap and the best ways to free up a few bhp without spending big bucks.

note - yes, cams, throttle bodies etc etc can get you more but thats not the point of the thread. as for driver experience we dont know what level of experience noodle999 is, after all he bought a trophy so which is a good handling car and that rarely happens by accident i assume he is a car enthusiast.

my point stands, if you want to mod you engine in a basic bhp per £ and stuff you can remove later a panel filter,exhaust and remap are the bread and butter.

we had a trophy in work with a janspeed, sounded the nuts! just a little louder than std, but loud enough to know it was modded.

Hi guys,

Basically I think my plan is to get a replacement panel filter (rather than some big noisy induction kit), have the intake matched, fit a Janspeed system and then have it all remapped to see the optimum benefit from it all.

Sounds like the list of mods on my own car.

I've got the ITG panel filter, removed the acoutisc valve and piping and replaced with a nice 85mm CAF.

The Janspeed system is a perfect replacement, nicely made single back box design. Massive saving in weight and sounds just right IMHO. Not too loud or annoying. I have probably heard most of the popular exhausts on this forum and while they sound great when you first hear them, I don't think I could live with them longterm with maybe one or two exceptions.

I've also got matched inlets from APD and a custom Superchip remap from Sanspeed. I went this route a recommended by Mark Fish and a few others. Increased rev range (you choose) and before and after rolling road printouts. In fact I got a total of five when I had mine done.

All of the above make a nice improvement, but my favorite mods have got to be tweaking the suspension and geometry and brake upgrades.

I've carried out similar mods except I have a decat and use the std. filter. I'd say go for it. The improvement on mine low down is drastically noticeable. It pulls a lot smoother than before. I think it's probably added about 10-15bhp on my 172, mid range even more.

I wasn't that impressed when I initially added the inlets, but when it was remapped it tied all the mods together and was much better.

Cheers for all the advice guys, it's much appreciated

I am considering something along those lines at some point, because regardless of ability there's always going to be benefits, but without wanting to incriminate myself believe me if I didn't know what I was doing I'd have written it off by now!!! My concern isn't going faster around corners, I know the car's limits and it being a Trophy, they're fairly high...

What I'm more interested in is changing the characteristics of the power delivery to rid it of some of that relative gutlessness lower down in the rev range, and smooth out the mid. Let's face it, perhaps 90% of the quoted bhp of a 1*2 engine is available in about 15% of the rev range? Until it comes on cam you're getting nowhere near that. If I gain some peak power in the process then it's all good :approve:

Cheers for that 7MAT, sounds like you're the man to ask about it then seeing as you've got a Trophy with the sort of mods I'm looking at As you had it rolling roaded do you mind me asking what the before and after figures and curves were like? Also what are the details of your brake mods? That's one of the things I've pondered also :approve:

Cheers Nigel, power low down is one of my main criticisms of the standard setup...

Cheers Danlp6, sorry I didn't spot you. I'd been to Weston super mare with the kids.
