Quote from: Petrus on July 15, 2019, 23:29There are several even lighter options than the RPF1 but these are the only ones readily availeble in Europe and furthermore the best quality/specs/price.
I would have preferred Volk CE28 but alas; practically unobtanium, too exotic, too overpriced. They are roughly a kilo lighter but come at 2.5 times the Enkeis.
As such the RPF1 is the gold standard.

The 7J was forced upon me because of availebility; 6 and 6,5 would have been lighter still. As it is I am very content because the 195 front suits my style better than 185; it is just taht bit less initial understeer.

It is basically a lot of fingerwork but for rim weights I found a quite extensive russian table as the only reliable source.  It was earlier in the his thread:

Hey,
Nice find, i too purchased some nice light weight wheels. Altho they are old school i kinda like them because they came at a little to no money plus original caps that can be sold for the amount of money i bought the wheels for. Give them a look ATS Cup limited line forged, sites state 5.5kg but when i weighted them a wheel came at 5.65 which is still nice. Not sure they will fit but they fit mx-5 so i think it should be fine. I wanted something 8j and more but when i saw these decided to give them a go.

On the width side of the above I think your style suits square setup as the turning is a lot more controllable with the screamer pedal. So if you can try a car with 205/205 i think you will like it.

The wider the rim, the heavier Nvy and I would have prefered stock width, thus lower unsprung weight 
It is só noticable; conformation is só much better.
Earlier in this thread I explained I looked hard, hárd for Volks CE28 but... Very content with the RPF1s though and as a bonus they imo do look a lot more classic than the Volks. Hardly surprising as they áre true classics by now 

Btw Ardent; searching for ´JDM wheels´ turn up quite a lot used rims. There was a set of supermegalight Volks for sale in your neck of the woods even. I could not get them here (a-hole seller), otherwise I would have a set of 3,5 kilo red club racers fitted now.

Right, enough internet; farm work to do....

I had 205 on the front and hated it.

Best wheel and tyre combo I've had is stock PFL on AD08R.

This thread and exchange of information put me in mind of this from Arthur C. Clarke:

It is vital to remember that information - in the sense of raw data - is not knowledge, that knowledge is not wisdom, and that wisdom is not foresight. But information is the first essential step to all of these.

This morning modified the inlet of the standard airbox.
Since the original horn/elbow is the way it is with very good reason I prefer to retain it and accept the flow restriction at the high rev end.
The duct through the inner wheel well is not really a limitation and basically only reduced inlet noise.
With it gone though, the entry of the horn can be improved; the bell shape can be opened up entirely.
In itself a very simply job but mán what a fáf is that plastic of the inner wheel well, more accuratelty the old brittle plastic push fasteners.
Anyway. done it and as a bonus it is 750 gramms removed:
3/4 of a hp extra, 3/4 of a kilo less; there we go 






Now, if we can do a group buy of the TRD horn for sale, I could do a comparison :-)

The bummer is that you don´t know what you don´t know; that there is always more, ALWAYS:  A vital bit of key info dropping into place a lot, is boúnd to be unveiled áfter you took a plunge :-(

Nice one - so what's it sound like?

Ah, you got me there: Had left the rhs door ajar over a few days and the battery is quite flat.
So tried to use the rally car and... not flát but too low to start.
Have to wait till mountain girl appears with her SUV and it´s giant battery.

Forgot the removed bit (apart from the ring sawn off from the horn entry):

Appreciated.
Theres tonight's project

Wow, thát is unexpected.
My son was a bit clumsy with the starting cables; was not deciseve with the last clamp and the clock needles did no know whether they were coming or going.
The engine started though.
So took it out for a spin. Runs and drives ok; at lower revs a bit more crispy pick up and ditto more crispy exhaust note; more racy. But then it started cut out on tick over and the engine fault lights up.
Back twards home, stuck in the Torque OBD reader and ... no blue tooth.
Hmmmm.

Took out the one from the SUV and ... no blue tooth.

Meanwhile car started tick over ok but then the radiator fan kicked in so with no blue tooth, there was not much reading out fault codes.

Can there be any fuse blown out because of the starting cable or ... ??
Checked fuse 16 (OBD)  and 33 (ECU-B) .

@Petrus

Having just looked up the Volk CE28. Based on no more than asthetics alone.
I prefer RPF1

As I said, the looks compensate for the extra kilo ;-)


Ok, the drive to the coast and back.
Highly enjoyable!!
Both the girl and the car ride. A máss of soft, lovely smelling curls rolling down to half way her back, near black eyes you can fall into and a mile to fall in love with. Oh and bríght; has a construction company she set up herself from nothing.
But back to the business of a car forum...
It is a minor mod so the difference is marginal ofcourse but more noticable than I expected.
The car is simply more responsive.It feels as if the air in the duct needed accelleration.
I went back late (or early) and that means just about empty road over here. Just the exhaust note filling the wonderfully cool air.
Put on my cap and pulled it well down so as not to have the last of the fuzz blown off.
Over the pass, the last stretch homeward pushed it well into the three digits and same thing all the way up the rev meter or speedometer; the car is more responsive.

The ECU found relearning a bit of a challenge appareantly. Idle was consistent but too low.It was not untill this morning that it had an ´aha-erlebnis´ and found the proper idle speed.
This too illustrates that the de-duct has effect.

The wheel well space act as a plenum chamber and also as a still air dust trap.
Flow wise it múst have a positive effect in combo with the bell shape entry and that is very noticable.
Power wise I think you need it measure with an amplifier on the dyno to see a difference.
Dust wise I think that in most parts of the UK you can get away without the filter element. With the OEM plast horn the taper is probably more restriction than the filter but with the TRD pipe, I would be tempted even here.

Botom line: Very worthwile mod imo.
A hour of faffing.
No money involved.
750 gramms lost.
Responsiveness gained.

Looking forward to other experiences.

p.s. just cut the ends of the two plastic screws behind the fuse box off. That way you can leave the forward bit of the plastic inner skirt fitted and just drop the mid/rear on the tyre. The scres are just about impossible to get out anyway as the threaded plug in the sheet metal turns.

Tonight the c-company suggested we go out for a romantic spin under the mountain-bright wonder-full moon.
Got the car from the port, folded the roof down, drove it up the ramp and there, in the beam, she was waiting...
stark naked!!
Ok, save for matching pink high heels and mini backpack which later prooved to contain moon lit night fun stuff
She likes the car... she says back at the farm.
Who am I to disagree

The deduct apparently had more effect than I expected; it confused the maf/cpu.
Probably just outside the adjustment range of the grime ;-)

After cleaning maf again, clean intake duct, squirt cleaning foam into the throttle body / evac hole, wiping clean etc., the idle speed has improved to my liking.

The sound is wícked now 
Have to contain my enthusiasm to rev it
I doubt that I could get away with this level of ´noise´ in the Netherlands or UK.
Last night passed through the village around 01.00 and got loud cheers form the village youths    so the police would no doubt frown oe worse

The charming company really enjoyed the ride but did comment on the floor matts. Finger crossed about her view on the new buckets 

At some point could we get an audio recording of your setup? I know you've got the pretty unique bike exhaust, but it'd be great to hear it!

Working on it.
My son should do that in the small hours early some morning but ever tried to get a teenager awake at that time?!
Extra complication is that I like to not always wake up at the farm ;-)
Just asked him and he thinks it stupid to the power of stupid but... ok. So, fingers crossed. Not when driving please.

Bought Dev´s improved ear strap from SC so this morning had a look in the tunnel to understand fitting it.
Despite the straps with the push buttons dangling loose, there is already something there!
Either end has a spring attached to a strap attached to the roof.
Appears that mine has an OEM replacement roof with ditto strap incorrectly fitted; Not first looping over the curved tube.
Unhooked, strap over tube, hooked up again.
Dev´s strap is surplus when it drops in the post...Luxury ´problem´.

Another day with the MR under the sun:
Passing through the village, thinking nothing,
Pilar, the lady of the post office, waves me down.
Urgent letter or a weird package, I think.
No; she likes my car she says;
a LÓT she says.
Wow that is nice, I think.
Thanks, you´re welcome for a spin, I say.
Oh my, I´d lóve that, she thinks.
Pick me up at six, any day, she says.
Lóve my car, I think.

The springstrap was too tight; deformed the hood both up and down.
Not a success,

The cars itself however...
Went down to Marbella for late lunch with a lady.
Over the pass was passed by a Seat suv; beepbeep and someone waving. No idea who, nor sure me waving back was noted.
Halfway down the Seat appeared to wait for me to paas so I oblige. Ah, now I see; ´Kippen-Loli´; the womoan running a chicken/meat stall in the municipal market, so I wave.
Waiting for a trafic light in Málaga; beepbeep, Hola Piter!!! she stops next to me, window wound down, smiling as broadly as the car permits. Que guay tu coche!!

Lunch date is a weírd woman. Amusing but no car link.

Then went further west to pick up the evening date. The curly mass girl.
She loves the car mostly because I enjoy driving it so much.
Although she has a trim figure, is not a big fan of how low it is so shakes her head about the planned seat transplant. We have this running gag about me all too often having coincidal brushes with fuller figure women* and she quibbed; ´good thing you always have lube in your bag; so the chubby fits´...
 
* if I take public transport the large one sits next to me
if I go to the cinema, the large one needs to pass through to the other side
at dancing class, the large one asks me
if I offer to carry the heavy bag of a women at the supermarket, it belongs to the large one behind her that was shoving away her cart

Now if you win the lottery over here, the saying goes that ´ha tocada el gordo´ ; you had the fat one.  In mý case the joke goes  that ´ha tocada la gorda´;  I have the fat lady.

Anyway, just changed the strap hook up. Going to the village in a moment and see how it works out now.

A series of interrupting time sensitive ´priorities´ keep pushing the mounting of the buckets back.
Quite frustrating but I dó need a bit of a time slot when I don´t need the car. The combination is usually not an issue but ofcourse; when you wánt it, it is.

Just this morning had to move the box with the seats and .....uffff... the two of them with packing material in a carton box way significantly less than just the passenger seat.

Meanwhile two other cars need more urgent attention so, next week it is. I hope 

The passenger bucket on the adjustable (RHD driver´s side)  OEM mountings.
At the front the bolt are already loosely fitted. At the rear the OEM brackets need to be raised 4 cm.






The driver side will be mounted on the current onder under the OEM seat.

Both OEM seats will be put on the non adjustable runners so they can be refitted in minutes. Either for a charming company objecting to the polyester bucket of for MoT.

The new seat do look rather spartan btw. which is multiplied by the absence of plastic covering rails and mechanism. Now Í like that but the c-company... well, let´s say not. I will not say even that about the comments and threats about the expense/comfort, but as she concludes; I do what I want anyway. So true :-)

Well that's a marked improvement on your first attempt at replacing the seat
