S70 cd 1997

[jamesy12345]

Always use a sat nav for the speed, the gps is far more accurate than a standard speedo. My s70r was 3mph out at 70 and the faster it went the further out it was.

Yes I noticed the speedo was a little high compared to the sat nav on my phone. Good to know

As can be seen from the gratuitous vacuuming shot above, my race number was T672 at York....they have updated the results:

Well folks, after a tour of the scrap yards of the United Kingdom of Great Britain and Northern Ireland (plus some in the Republic of Ireland too), I have secured…..

An 18T turbo from a S70R manual
An AW42 gearbox with 2.76:1 final drive ratio as opposed to my 2.56:1,
Exhaust camshaft from a B5254 engine

So here are my thoughts/dreams......bearing in mind I got the S70 without any real plans for modifying it. The intention was to use it as a daily while I put my 480 back together......umm, 480 still on SORN, meanwhile......

The 18T I just got cos it was going cheap, it probably won’t be much use unless I change my TME map for a custom one. Until then it can live in my kitchen so it can be a discussion point at the dinner parties that I don’t have. Looking at the compressor maps there isn’t a great difference between the 16T and the 18T although of course the 18T can flow more air at 485 cfm compared to 435 cfm max.

The naturally aspirated cam I was hoping to get a little more lift for exhaust valves…..I may try the inlet cam also but I was a little worried about overlap. Maybe this is not a problem due to the straight through cat & exhaust – not much back pressure……? If I need to sacrifice my 30 mpg for flames out of my back end (ooer) then I can live with that . Anyway will try exhaust side first. Some data for the difference cams:

T5
Intake:242 duration 7,95 lift
Exhaust:243.5 duration 7,95 lift

N/A
Intake:250 duration 8,45mm lift
Exhaust:252.6 duration 8,45mm lift

I’m sure there are a few folks out there who think it a daft idea to fit an auto gearbox of any kind, but what I am trying to do with the car is to make it seem as standard as possible, including how it drives, while also making it pretty quick. I’m hoping to manage a quarter mile in the 14’s with some or all of these parts (my secret plan is to reach the 13’s but need some practice yet/a following wind/nitrous injection ). The naturally aspirated 2.0 litre auto box has a final drive of 3.10:1 and the 2.5 engine has a FD of 2.76:1.

Info from here…. http://www.volvoclub.org.uk/tech/S70TechData1997.pdf

The gear ratios on all of the AW42 boxes are 1st 3.61:1, 2nd 2.06:1, 3rd 1.37:1 and 4th 0.98:1. With a 3.10:1 final drive the shift from 3rd to 4th at 6000 rpm would be about 103 mph, which is a little close to the end of a quarter mile I think so will try the 2.76:1 final drive first i.e. the 2.5 litre box.

That is assuming the boxes from the N/A cars even fit onto my engine and can withstand 420 plus Nm….I heard from TME that the transmission case on the turbo auto boxes are stronger from 1997…..hopefully it won’t dump it’s load into the bleach box at York! With a 2.76:1 final drive the shift point from 3rd to 4th is about 116 mph for 6000 rpm, so no need to look for 4th gear before the quarter mile is up.

Oh and going to pick up a couple of Avon ZV5 tyres to replace my rubbish Rainsport 2’s, not bad at 65 quid each on the Camskill website.

So, in short, do you want shorter gears or longer gears?

haha my post was a bit long wasn't it. Short I think mate, so higher revs for the same speed. The AW42 box with a 2.56:1 final drive gives 183 mph in fourth at the rev limiter...seems high to me when the car probably can't pass 160. The box with 2.76 final drive gives 170 mph at the same rpm (6250)

If you were going to put another auto in, then a shorter one would be better, as the standard one has pretty high gearing (sure 2nd in my s70r would go up to mid 70s?).

Have you thought about the gearbox ecu? Will your car need the ecu from the car that you are taking the box from and will your engine ecu work with a different gearbox ecu?

Just wondering if it would be simpler to go for more power........though i would definatly suggest getting an extra cooler for the box (whatever you decide) and also suggest forged rods if you are going for a bigger turbo.

Yes the gearing is high on that box isn't it! My video in the post below is with the same ratios...

80 mph in second wtf is that about?! It's not a motorbike...."Excuse me sir you were speeding"..."Surely not officer, I was only in second gear"

Thanks for the comments, yes I did ask for the ECU/TCU just in case my existing one doesn't suit. Probably yes would be easier (not easy but easier) to go for more power but I wanted to try the box idea as I couldn't see that anyone else had tried it....maybe there is a good reason for that! Another note to self: don't post until you have actually done the job

I have asked my local dealer to get me a price for the transmission cooler (part number 9492 870-2 for the 4-speed), you're right it would be useful for any box I have. Assuming the 2.5 box fits at least I'll have a relatively cheap spare if something goes bang. Plus I'll have a spare ECU to fiddle with to change the shift points.....

http://volvospeed.com/vs_forum/topic...r-development/

From page 4 onwards, Lucky from ARD shows how changing the resistors out can adjust the gear changes.

I was wondering about the rods.....reading bits and bobs on the forum seems like I am not quite up to the power levels where I should worry about it…but yeah if the 18T goes on maybe it should go on the list of jobs. Will get a look at it when it comes, I think the M4.4 18T turbos were straight outlets, and the ME7 18T’s were angled outlet. I heard a rumour (from Jan Woth) that ME7 turbos on a M4.4 car are hard work to get mapped correctly. The reg number of the car it came off was S172 JNL anyway, will find out.

edit: I spy a throttle cable on the donor car, M4.4 it is then

Comment from Jan on ME7 18T turbos...

The 18T turbo from the B5234T8 is not optimum for the B5234T3 due to different turbine character

Good news everyone!

It takes less power on an auto to bend a rod, due to the nature of the gearbox.

i have driven at an indicated 159mph in an me7 v70 t5 auto and it was nearing the limiter

Yes I was worrying about that, quite easy to get into high boost with low revs. A lower ratio box would help...a bit. Forged rods will help more tho

I got 148 at 5200, my driveway wasn't long enough to reach the limiter

not bad at all, would be over the moon if I can pull near that!

only reading this for the first time lol how did that happen? had a good browse through the 850 brochures nice find!! see there was a 320mm brake upgrade from volvo for 17+ on the 850

What's that Marty....how did what happen? I saw those brakes, not sure how much they cost but I better start saving. My discs are a little bit warped at the front I think - you can feel a little vibration when using them hard before the ABS comes in that is. Nothing serious though!

edit: oh did u mean Andy's time? In the quarter mile league table his entry reads.....

23)14.436@101.85mph - Andysr, 854R Auto, T28/15G, TT, JT exhaust & cat, S60R greens & manifold.

So a hybrid turbo, turbo tuner ECU (?), bigger injectors, later model manifold and an exhaust to match is the answer! And a good lauch

It’s been a busy old few weeks! I still managed to squeeze some jobs in…..

Fitted the ‘media changer’ USB/aux reader to the SC-805 head unit, thanks to Brett855TDI for that, what a great piece of kit – I have been driving about listening to the music he sent me over on a flash drive – very cool (different to what I usually listen to). I’m not 100% convinced about that snap connector though to supply power to the unit via the yellow wire in the picture…..maybe will change it out for a soldered connection or at least crimped……:s





Ebay linky http://www.ebay.co.uk/itm/USB-SD-MP3...item1c336950d3

Changed the engine oil and filter, stuck some 10W/40 in there. It was a little bit noisier starting up on one of the colder mornings but seems OK. Drain plug is at the back of the sump, oil filter is located on the right-hand (driver’s side) of sump in the vertical position.





Changed the auto box fluid. It was just some cheap stuff that went in there but it did say it was equivalent to GM Dexron VI….it was called ATF-U…linky http://www.carlube.co.uk/index.cfm?product=153



Changed the coolant ready for the winter…..and put a new expansion tank on there. Totally forgot to get a photo of the new tank, it’s just out of shot in the next picture. Fitted the blue injectors (thanks MRP!!).



Can anyone see anything wrong with this picture? Yep, the injectors are upside in the fuel rail. Honest I changed them round before sticking them in the engine and firing it up. Honest I did

Remembered to clean the injector seats also….



Just for reference, my car was fitted with white 350cc injectors. These blue ones are from the ME7 cars (P1 from ’99) and are 395cc at 3.8 barg but I am reliably informed by the guys on here that they are still 350cc at 3 barg. A bit of info below:
