I will pm my postcode so you know where to send one of those boxes:thumb:

Well - collected it today from Iain with the repaired downpipe. It's running very rich, but nevertheless it's "chalk and cheese" compared to before. Actually, I think Len (Subaru4You) and Iain stitched me up and pulled a fast one, I don't think they really fitted the LM480 at all - there's simply no comparison http://www.hampshiresubaru.co.uk/php.../icon_wink.gif http://www.hampshiresubaru.co.uk/php...s/icon_lol.gif

It pulls like a train, with a wallop in the back in any gear as it comes on boost - but very smooth and progressive with it, right the way to the redline.

In 6th gear, boost reached 1 bar at 3000rpm, and 1.8bar at 3300rpm; Iain hopes the map tweak will lower that further still.

The car is bordering on being a bit scary now - I've never had torque steer in a Scoob before but it's got it now http://www.hampshiresubaru.co.uk/php...n_confused.gif - and insane speeds are reached immensely quickly. Grin factor - ten out of ten http://www.hampshiresubaru.co.uk/php...on_biggrin.gif http://www.hampshiresubaru.co.uk/php...on_biggrin.gif http://www.hampshiresubaru.co.uk/php...on_biggrin.gif

It's booked in for a map tweak - and, hopefully, the "megarom" per-gear mapping - on Thursday with Simon/JGM up at Len's so, with a following wind, RR figures will follow at the end of the week.

I had one instance of clouds of oily-smoke out of the back (one of the issues that caused us to draw breath and get the car to Iain's in the first place, as the turbo was possibly to blame). This was after the first blast after crawling through the slow Newbury traffic - I stopped off at S4U after picking the car up from Iain and it had been fine up until then.

I'm 90% sure it's related to the catch can breather which I think is a bit pinched by the bonnet. I have a new custom 3-inlet unit arriving in a few days so will sort it properly then, and run the vent pipe somewhere out of the way.

For now, I'm just pleased to have it back http://www.hampshiresubaru.co.uk/php...on_biggrin.gif

Well done tim i bet your'e buzzing mate well done to all the partie's involved..

Tim,
If you are getting what feels like torque steer, you need to get the handling set-up looked at. You will probably find the front is lifting too much and causing the steering to go light. I had the same problem and sorted it with set-up changes in the handling department. I have more torque than you and I don't get that problem now, so it can be sorted. :)

Hat's off to Litchfield Imports for sorting your issues out. :)

I've got the "usual" PowerStation/Litchfield setup with ALK, uprated ARBs and ASTs...so what do I need to look at/tweak to sort this out, Shaun?

Tim,
Have a chat with Iain...... he knows all about this area intimately and has vast knowledge/experience on how an Impreza should handle on the road. I would suggest you book Iain for a couple of hours to set your suspension up to teach you "feel" and how this can be altered with the suspension. He will be able to do this WITH YOU on the road. I did this with Iain and my Spec C when I needed to understand how rebound and compression works with what I was experiencing on the road. It was invaluable in understanding things for my own good and after minor personal tweaks of my own (after Iain and myself agreed a very good base set-up), it was the suspension set-up that did the business at the last two rounds of ScoobySprint last year. It's all about "feel" and not about "how many clicks". Big differences can be made overall with tyre pressures and geometry, so it would be worth ensuring everything is balanced. Again, Iain has all the equipment/knowledge/experience for this as well.

Within a very short period of time between Round 3 and Round 4, my car went from "dog" to "god" with the help of Litchfield Imports (suspension set-up), Tracktive (geometry) and AST UK. In total it took about 2hrs with Iain and then geometry changes with Tracktive. A lot of people profess to be experts in this area, but I only trust those with results that back that up.

The car has been "scary"...... now it is controllable and very quick. There is a distinct difference. :)

Thanks Shaun - I think you have 3-way adjustable ASTs whereas mine are the lowly 12-ways, where you can only adjust rebound. I have played with the settings in the past and have settled on a softer 5-off-softest at the front for the road, compared to 10 or 11 on the track - I will have a play and see if the harder settings minimise the lift/torque steer.

Having just paid Curtis to service the rear ASTs (including one brand new one as it was seized :() I don't really want to junk the correct setup just yet ;) :lol1:

But I will speak to Iain in due course, once the map tweaked and I'm more used to the car :)

Tim,
The single adjustment on yours adjusts both rebound and compression. Yes I do have the 3 ways. You do not need this extra functionality for what you need to do though.

One step forward, one step back...clouds of smoke again this morning, so much so that it made the road behind me look very foggy :eek:

Parked up and found oil dribbling on to ground via the headers, in the vicinity of the cam covers. An hour or 2 later no oil on dipstick at all and a rather messy road :(

Looks like a seal's gone somewhere (at least, I hope that's all it is). So, deep joy, it was back on to an AA recovery vehicle to be taken up S4U where it's now patiently waiting to be looked at :cry:

At least you're getting your money's worth out of your subscription Tim !!! Am not laughing really ... honest.....

:( I hope for your sake your bearings have not picked up, if your oil was that low.

Oil pressure never dropped - my son was in the car as we limped home and he had his eyes glued to the gauge with strict instructions to holler loudly if it dropped at all, which it didn't.

And, at least the engine's still in warranty!

Well gents picked my car saturday and must thank Iain and the guys for an A1 job. :thumb:

Everything has been done as discussed and he has even lent me a ECU with a base map on it so i could get back home on.
As it wouldn't run with my Simtek at all, now just gotta wait until Simon (JGM) remaps my Simtek tomorrow, then it will :D:D:D:D.
Must admit it already sounds very :D

So i'll be posting up my results once its all finished tomorrow.

Mel

Good to here Mel!

To say im :D:D:D:D is an understatement!!!

Big thanks to Both Iain and Simon for all you help :notworthy:notworthy

Mel

Excellent results mate :)

So good in fact, makes me wana keep my Spec C & do what you have, iv got a lot of the bits already apart from turbo & injectors ;)
You need to do Silverstone with us & see how it performs on track.

Looking good :D And right on the nose power-wise for the LM450 :D :D

Will standard internals be OK for 450bhp?

Pleasure Mel.
Nice to have met you and love that car!
Simon

Yes :)

OK - I always thought 400-ish was the sensible limit for the JDM 2.0l?

Anyway, fingers crossed we'll get 480 bhp and loads more torque on mine this Friday :D

PS - oil leak was a popped exhaust cam seal due to excessive oil pressure. New oil pump and seal being fitted tomorrow, hopefully :)

Brilliant results Mel/Simon, right on the money :D That is a massive useable power band, bet it feels really strong in the mid range as well!
The colour, wheels and now the engine make just about the perfect Spec C!
Iain
PS don’t forget to send back my ECU ;)

I hope Friday goes well for you Tim :)

Iain,
Cracking results. :)

Mel,
You must be over the moon. Looks from the graph that it comes on boost really well. :) 1.5bar at circa 3700 on a rolling road, would suggest it would pull boost sooner on the road in 5th / 6th. :) Nice one.

was a good day really.. the blue uk 99 I mapped after your car Mel

Attachment 62765

:)

Simon

Great result, almost makes me want to convert to twinscroll

Thanks for all the replys guys.

Ricky - take that for sale ad down mate!!! :D
Ring Iain and get the conversion down, you def wont be dissapointed. If you want we can meet up soon so you can have a test drive to see what its like. When is the next silverstone track day by the way??

Iain - ECU is wrapped up and ready to come out to you this lunchtime, cant say thanks enough for the loan of that. :notworthy

Shaun - Its seems to drive pretty much as my old turbo did so really glad i haven't the driveabilty of the car and due to the lower gearing of the JDM 6 speed box 5th/6th are just as lively as 3rd/4th :D.

Simon - I know Mikes car would make great power, its was in good hands.
Bet he has happy he has moved up on Charlies wall of fame now :D
p.s cold starting this morning was spot on too!!!

Mel

Mel send me a pm when your gona be free, we'l try & meet up & go for a blast, I need a passenger ride in that loonatic Spec C of yours!!

Great results Simon :)

Nice work Simon, 35/42 equipped 2.5 ?

Mel

Cracking results :D
