Its great what Sandy is doing but ive also seen very interesting figures from people in the Rally community (especially over in ireland).

I cant really see there being much more room for improvement from these engines mind. We are probably as close to the max figures we will ever see.

Are you referring to the JRE engines that are in Ireland?

I'd imagine we are heading towards the maximum figure, but Sandys still striving for even better so you never know. There's about 5% between the RR figure and what the engines actualy capable of on the Engine dyno - I plan to open up the scuttle slightly to allow better air flow to the middle two cylinders and see if that helps :)

Theres a few independents that have got good power.

Its a shame that QEP and everything went to shit, as the dyno testing they were doing with Dave from Pumaspeed was proving very interesting.

No scuttle FTW :D

http://www.106rallyeforum.com/forum2...highlight=maxi - incase not read this, an interesting read on both his figures/the final production ones from oreca.

Sandy309 26th September 2012 06:28

Alot of the JRE engines I map on our engine dyno go to Steven Gault's rolling road once fitted in the cars over there. I know how the figures for those compare.

The last engine I dyno'd in this spec (engine dyno, DIN corrected and calibrated, not to be confused with the vagueness of rolling road figures), was almost identical to Josh's, the only significant differences were Jenvey SF bodies on my own manifold (same tract design effectively as Josh's) and the same geometry exhaust, made by a different fabricator. Peak figures were 234bhp at 8500rpm (as far as I tested it) and 159lbft at 6500rpm, with two slightly different inlet configurations. I tried alot of different injectors and injector positions, cam timing etc to arrive at this, two days of dyno testing on an engine I've already developed extensively.

Here are the figures for two inlet tract variations I tried (these are the stable recorded steady state figures plotted on a simple Excel spread sheet):


Pictures of that engine on the dyno, showing some of the inlet/injectors variations I was testing:






Pics capturing the readout (DIN figures are what matter and ignore the Lambda display, we were using a separate one), believe me it was quite an emotional moment when I saw 230bhp+ for the first time!




Before everyone gets too carried away with peak or wide open throttle figures, I should point out the range of other qualities I have achieved with these engines that I'm proud of and I feel makes them stand apart from others... Driveability (they are totally road friendly and little need to be revved to perform), economy, no oil or water leaks even after a couple seasons, negligible breathing and oil consumption, so far total reliability and aside from the glitch with Josh's fuel system, after I've trimmed the map in the rollers and/or on the road once, that's it, they run sweetly until the next rebuild.

I regularly dyno other people's race and rally engines of similar spec that customers have paid in the region of £13-15k for and don't perform anywhere near like this. I haven't got a set price for this spec, because individual builds always have a certain amount of variation, customers have an ECU already etc, but from scratch, with OE crank, exhaust manifold, ECU+loom, race clutch and steel flywheel, dyno'd and ready to use, it's about £11-12k. I do limit my builds, because of the other ongoing commitments I have (about half of my work is mapping, wiring and development for other engine builders; also the need to do scheduled work on existing engines) and currently the waiting list is well into next year so I'm afraid I can't really consider doing any more just now.

jsdvtr 26th September 2012 10:11

Always wondered what sort of price these engines were. Cheap for a race engine though and in comparison to the work sandy puts into these engines to say pug1off which they use just some atpower itb's that are universal rather than custom to the engines spec along with things like the valves not being off the shelf and being machined to suit.

Can see why it takes months to build too, spends day and half just on a loom and I was very impressed my loom he made for me.

Ryan 26th September 2012 16:24

Thamks for the write up sandy. As mentioned previously fully aware of some of the 'dark art' as such any information shared is fully appreciated by a large number of us on the forums.

I don't suppose you happen to have experience of the air boxes used in the rallye reg link? I've got one here but it's just the air box at the mo and no mounting system etc for me to see about putting it together. (I'll grab a pic when back on my mac)


Sandy309 26th September 2012 19:22

I'm not really a fan of airboxes, they always have side effects and although they can lower the inlet temp in a static situation (ie queuing for a start or on a rolling road, out on the go, they really don't make much difference. I say that with quite alot of testing experience to draw on! My engines rely heavily on inlet and exhaust pulse tuning to do what they do and the air box design can profoundly affect that. Although I've seen airboxes produce spiked figure improvements on occasion, I've never yet seen one improve the delivery overall and single entry ones, like plenums, don't ever sound anything like as nice as open induction. On forward facing engines I like to have a nice wide open airbox where practical, that doesn't impact the pulse tuning; example, here's our 205 hilllclimb car, which we did as much to split and manage the ingested air to the rad, as to the induction:




Ryan 26th September 2012 19:24

Im not a fan of them either, but I cannot run on some tracks as it currently stands :(

hard_corejoeboy 26th September 2012 21:15

That looks properly fun. What sort of league is that car in?

Sandy309 27th September 2012 06:09

2 litre modified production hillclimb and sprint.

More about it here if you're interested: http://forum.205gtidrivers.com/index...owtopic=140057

Alanapone 27th September 2012 22:21

That 205's a BEAST Sandy :D

Jay_ 27th September 2012 23:58

I always love your write ups Sandy! :y: Top man for sharing so much info!

jpsaxo 20th October 2012 12:36

Ok time to properly update this from the start of 2012...where do I start?

So to begin with we stripped the car for Mark to do his work on it...





At Marks...



In progress...





Primered



And painted





And the underneath all repaired, stripped and painted/stone chipped






jpsaxo 20th October 2012 12:36

So then we began to build it back up... Satshifter & steering shiz first



Gearbox was rebuilt in the mean time, all bits were strengthened... (Thanks Tom!)





Carbon Lorraine RC5+ pads



Relocated both fuse boxes in behind the dash



Mark finished the CF Bonnet



& fitted the CF-look areocatches...





Fitted a proper SPAL fan


jpsaxo 20th October 2012 12:36

Now was time to fit the engine....

As most know; this is a Sandy Brown top 2012 spec producing silly power for a jp4 NA engine :D

Sandy finished the engine in the back of his BMW lol



Put the engine in



Had a few issues along the way...



So out came the grinder lol



Oil cooler fitted



Modified the catch tank...







Fitted Sandys engine race loom





Dad made a bracket for the coilpack to sit neartly next to the engine...









Had a few issues with the clutch being too hardcore for the standard gearbox selector arm...



so that was beef'ed up by dad



and sprayed of course




Car was now ready, Olly then Trucked us down to 'Mike Edwards' for custom manifold / exhaust making & fitting to Sandy's spec










jayline 20th October 2012 12:56

looking good matey, really do like how far you have gone with this especially as it started of as a normal westcoast! :D

jpsaxo 20th October 2012 13:17

From Mike's we towed it down to Sandys for lift off.... dad did an epic Leicester - London - Cornwall & back to Leicester trip in one day!

After a few issues we eventually got down to mapping the following day...

The magician at work!



The engine was mapped as far as the standard pump could supply enough fuel... so I drove it back home to Leicester that evening and ordered a new intank fuel pump which was to be fitted as soon as it arrived...



In the mean time the manifold was turning nice funky colours :D



Mean while I set about adding a few lightening touches (battery weights 960grams!). My brother also made a DIY cage for the battery to hold it in place :)





Couple of ring stickers added (of course!)





Shift light carefully fitted & secured into the dash buttons



Tom Kindly offered to give it a good whoring :D




jpsaxo 20th October 2012 13:18

The fuel pump then arrived so we fitted that (what a bastard!)

Old one



New one



The problem (too big!)



I also tracked down the 2 remaining westcoast badges in the UK (one from up North & the other from Northern Island!)



Some Chimp (cheers Nick :D) also sent me my Mango citroen badge back.... lol



Couple of other bits in my obsession to make it as reliable as possible (old vs new)


jpsaxo 20th October 2012 14:24

The end result...





RED graph with old fuel pump

BLUE graph with new fuel pump, you can see a clear improvement from 6,750rpm all the way to the limiter




jpsaxo 20th October 2012 14:38

TRAX 2012

Then it was time to have a bit of fun in it before I returned to the land down under to see the Sun :P





Best Saxo 2012 award :D





I also had a bit of fun out on track....







After Trax I popped over to Mallory with Lee to get it weighed... 805kg with half a tank of juice, just need to find another 5kg of weight saving now lol



Finally it was time to store it away for the winter while im in Sydney... gave it a lick of paint first (with the help of the mrs & my brother!)



And you can see it hiding behind my shitbox 106XR daily up on Axel stands with no steering wheel / ECU / Battery etc



I certainly wont be forgetting it while im away :D


BIG 20th October 2012 15:12

wicked build i love this!

jpsaxo 20th October 2012 15:46

The main 2012 update is on the previous page guys :)

Couple of videos;

Sandy having fun in the first mapping session (OE fuel pump)



And the first RR run (with OE fuel pump) - You'll need the turn the volume up for this one as my car has quite literally wrecked the microphone on my iphone 4S lol :D



And finally Sandy having fun on the rollers with the uprated fuel pump and over 220bhp's under his right foot :D - You'll need to turn the volume up on this video as well because of my wrecked microphone lol



TRAX Silverstone 2012 video of me on track, kindly taken on Ross's GoPro :)

Bedford126 20th October 2012 16:03

If I'm honest I have never really liked the colour,

But the work gone into this from sandy to mark you and your dad ect... is just way beyond. That exhaust manifold is amazing its more art and the fact it's made for function over looks is just brilliant.

welshpug 20th October 2012 16:21

I think mango is great but its spoiled with the black arches and boot floor :(

Beaniemoo 20th October 2012 20:29

Finally got online to update lol!
Loving the update, car is awesome.

Olly 21st October 2012 00:15

Nice writeup pal.

Rofl ing at the xr still has a rim job.

Mathias 21st October 2012 00:20

Love the car, love the engine, love the colour, love the detail and effort!

Basically love it!

Edit : love the carbon!

rhysg 21st October 2012 00:52

Amazing progress to say the least !

piggy123 21st October 2012 05:05

Well what can I say.... Just been a pleasure to help develop this over the last 6 years from a shocker to a top notch heroic car :) ..... Nuts brackets and every last little thing not left to be replaced or attacked by the sander to get repainted.

You'll see her soon bro :)

Oh P.S.
Now it's my turn JP :p

RickP 21st October 2012 11:03

This has to be THE benchmark NA Saxo!

PJN 21st October 2012 14:46

Top car for a top guy, what else can I say, certainly one of the finest cars on here!

hard_corejoeboy 21st October 2012 15:58

Im waiting for the nurburgring videos...

Bobo0907 21st October 2012 19:34

Mango is nice! Love everything about this car.

Needs more pics of the exhaust manifold, that thing is a work of art!

Thanks mate, the whole car is made to be as quick & functional as possible, but also at the same time I've tries to keep it looking tidy, comfortable & driveable all at the same time. It's certainly been a fine line!

Yep finally got our Internet installed into our new flat and found a few free hours between 11pm-3am on sat night to update - yes it took me 4 hours to write this update. Main issue was finding the pictures on my laptop / portable hard drive / camera / phone lol

Cheers mate, you've been a big part of this ferrying the car around. The ring trip & lap in the legendary XR was pay back :D haha

:) it's been 8 years in the making but I feel the car is near enough as I want it now. Still some slight improvements to come but apart from that its 99% as I want it :)

The manifold definitely sets it apart from anything else I've ever seen. Mike Edwards did a cracking job on it :) what other pics do you want?

white_vtr 22nd October 2012 09:13

That manifold is the fucking tits!! Like saod, its a work of art! :) car looks amazing mate well done!

Just some more pics of the manifold! Any more would do. I didn't think a series of pipes could look so good lol :homme:

What other little changes are you thinking of?

Lol, I'll dig some out now...

Well I want to change the clutch, get a few brackets powder coated that I didn't have time to get done before, get a full interior loom made up to tidy that up & ill be getting some after market digital dials at the same time :)

That's the jobs for this winter, sounds easy but I'm only back in the UK for 2 weeks over Christmas between now and next summer, so need to get cracking over Christmas and get as much done as possible!

In the long term I need the upper strut brace modifying & scuttle opening up to allow more air to get more around the trumpets easier as I'm losing 10bhp+ from the engine dyno figure to the rolling road figure as it currently stands


EDIT;

Few more manifold pics...






welshpug 24th October 2012 12:34

Looks great, Mike does turn out some fantastic work, any pics of the rest of the system? what kind of bore is it?

hard_corejoeboy 24th October 2012 13:09

Love the way this is a properly sorted machine.

Powdet coating brackets now that attention to detail!

jpsaxo 24th October 2012 13:47

Half of them have already been done Joe, just didnt get time to do the rest as we ran out of time. Basically everything pre-engine was powdercoated where possible. I took a big box of bits and bobs to be done lol

The whole system from the manifold back was done by Mike. Its been done with proper push on connectors etc. I cant say any dimensions, primary lengths etc as we have to respect Sandys confidential information that hes spent months / years perfecting
