You guys are all a big pack of poncy wannabee wusses. *don't forget where I live it does go to -15C or so in winter - and we don't get the luxury of winter tyres!!

You big girls blouse Aussie wimp. -15c is a hot summers day here although it hasn't snowed here since Sunday so it's starting to feel like spring OK, you win that round. 2.5 hours south of my location is a mountain named Perisher - 'cause that's what happens to muppets who climb it unprepared. It's also the coldest place I've ever been - about 20 years ago, howling gale (120km/h+), lifts were stopped, white out, and a windchill of something like -50C. Not bad for Aussie wimpy mountains - it's only 2700 odd metres high. The second coldest I have ever been was a cold, bitter, biter of a 1996 morning on Copper Mountain (something like -32) when the entire full length zip on my high-end brand new Nevica ski suit just tore out... No one around the hotels (even Vail or Beaver Creek**) who would/could repair it - so it got left on the floor of a ski shop in Aspen and I walked out with a brand new super North Face one piece suit! (and a couple of grand out of pocket having bought 2 suits - including the Nevica inside a week). I might go for the personal best freezing my T*ts off record next year and do either the AMG or the Porsche ice driving camps in Finland... **where in a "steak restaurant where I discovered the septics wouldn't know a filet mignon if it was tipped over their heads, I taught 4 very drunk Texans some Aussie slang. The other patrons didn't quite know how to take Texans trying to do Aussie accents yelling out "dogs balls!" and other wonderful gems ("drier than a dead dingo's donger" etc).

chasdrury Posted March 24, 2015 Report Share Posted March 24, 2015 I was doing a project for work in Canada in January. 2 weeks there and the high was -17. Lowest we saw was -38 for a couple of days. Frikkin cold! Link to comment Share on other sites More sharing options...

eldavo69 Posted March 25, 2015 Author Report Share Posted March 25, 2015 (edited) Anyway! Also over the winter I fitted some higher flow rate fuel injectors, the originals flow 36lbs per hour at 2.5bar pressure but I'm running them at 3bar in line with the Stage 2 setup I have. The new ones are a set matched to within 1% of each other and flow 55lbs per hour at 3bar pressure. The fuel pressure rises in line with boost pressure and as I'm running higher boost as well I can flow up to 50% more fuel than standard when needed. These won't give me more power per se but they will give me more consistent fuelling across the rev range and also give me a lot more headroom for fuel flow for future upgrades.

eldavo69 Posted March 25, 2015 Author Report Share Posted March 25, 2015 (edited) A few last jobs before my next trackday, new fuel pump fitted, AFR gauge and sensor installed and then onto the Dyno for the Apexi to be setup properly on the rollers. With the previous manual boost controller, boost would spike at 19psi and then fall away linearly and the AFR would run very rich as the injectors tried to keep up. Here's the graph showing Boost at the top and AFR at the bottom and the HP at the wheels: With the electronic boost controller set to a target boost of 17psi and the new injectors you can see how the AFR is much more stable and the Boost is held longer too: This makes the car drive much better, less "all or nothing" from the turbo with a more progressive onset and sustained pressure too.

eldavo69 Posted March 25, 2015 Author Report Share Posted March 25, 2015 (edited) Here is the dyno chart from the other year, torque is the dotted line and crank HP is the solid line: And as it is now, the sustained peak torque figure makes the car feel a lot more modern in it's turbo-response: It sounds pretty good under load too: https://youtu.be/nTX4kF2UbYs Edited March 25, 2015 by eldavo69 1 Link to comment Share on other sites More sharing options...
Mook Posted March 25, 2015 Report Share Posted March 25, 2015 I like stuff like that We got an extra 22bhp and 25 torques out of my track toy by pissing around with boost and fuel pressure, to take it over 320bhp at the flywheel on the dyno, but it came in with a massive bang and dropped off, so driveability would have been horrendous. Two hours later, a much smoother power and torque curve means it's properly driveable on track anywhere from 2,500 up to 6,500rpm Link to comment Share on other sites More sharing options...
eldavo69 Posted March 25, 2015 Author Report Share Posted March 25, 2015 The first Trackday of the year brought a few little niggles to the fore. Firstly, the power steering pump came loose (again) so I removed the belt. The design isn't great and when tightening the bolts it pulls the pump halves in opposite directions. The steel bolts make short work of the aluminium threads on the pump too, I've previously had them helicoiled but after a bit of research decided on one massive bolt! Bolted from the rear of the housing, through the spacer and all the way through the pump, then nyloc nutted in place before running through the front spacer and housing before a second nyloc nut holding everything together. I may need to have a slight play about with the spacing of the pump as the belt run isn't quite straight but I can't really tell until I have the car running and the front wheels off the ground.

Mook Posted March 25, 2015 Report Share Posted March 25, 2015 Did the 944 ever come without power steering? I only ask because surely that's your better option. Less weight, less power sapped and less to go wrong. I took it off my toy for those reasons. Plus I'm strong enough to turn the wheels without any help Link to comment Share on other sites More sharing options...
eldavo69 Posted March 25, 2015 Author Report Share Posted March 25, 2015 The early cars didn't have power steering and you can swap the racks over, the issue is that they had different geometry so it was easier to use. I've also got an issue with my left wrist at the moment and had a steroid injection on Monday into it. It was painful at Cadwell (racing driver excuse #131) so I'm not keen to lose the PS. The other side effect of better boost control is that I blew an intercooler pipe connection off just after the pits and had to limp round for another lap before I could come in and do the jubilee clip up tighter. I'm currently waiting for an order from Lindsey Racing in the states that has 4 new silicon pipe connectors for the inlet plumbing system. These are longer than the stock items so will grip better on the pipes preventing that from happening again. Also in the package is a new billet aluminium fuel rail. The downside to more fuel pressure is that the crappy pressed steel and braised connections fuel rail started to weep slightly. I've had this issue before and just changed out the rail but it's not one I want as you can imagine!!! New rail is machined from a solid aluminium extrusion and is good for much more pressure than I'll ever put through it. The plumbing is a little different which will involve a couple of remade fuel lines and I'm also now going to be running an external adjustable fuel pressure regulator. This is good for up to 7bar fuel pressure so again that's another future upgrade bottleneck removed "while you're in there." In pulling everything apart I removed the factory airbox too - it's good for up to about 320bhp. It's a neat design that takes an air feed from the inner wing (although that caused the demise of my last car when it sucked in a whole lake). Some of the plastic tabs were damaged on it (very common, hence you nearly never see them available used) meaning it wasn't sitting quite right. I'm going to repair the tabs with a Plastex repair kit but for now have made a couple of mounts to support the Air Flow Meter and have used an adaptor to fit the biggest induction cone I could get to fit. This sits directly behind the intercooler so although sat in the hot engine bay (and 944s do run hot) it does get a reasonable amount of airflow when on the move. Doing this has also given me clear line of sight to the passenger side inner wing where I've mounted an oil catch can as part of the breather system. I'll get some pics up once my parts arrive and things start going back together. 1 Link to comment Share on other sites More sharing options...
eldavo69 Posted March 25, 2015 Author Report Share Posted March 25, 2015 (edited) So here's the massive air filter all ready to go: The hoses (not connected to anything) that disappear down to the bottom right of the picture go to the oil catch can: All snuggled down out of the way and the drain at the bottom is easy to reach by jacking up that side (although I hope it'll take a long while to fill all 500ml of it).

eldavo69 Posted March 25, 2015 Author Report Share Posted March 25, 2015 (edited) Fuel pressure regulator installed on the redundant cruise control bracket. The yanks stick it where the clutch fluid reservoir is on the firewall as it's part of the brake fluid reservoir on LHD cars. Where I've fitted it is directly above where the fuel line come into the engine bay so it's a nice short and direct run for the return pipe and across to the dampener (now in the country according to the USPS website). After enduring a rather "interesting" jaunt through the unlit b-roads of Lincolnshire the night before Cadwell I decided that the headlights needed some attention. Although popup lights are beyond cool, 26 years of movement hasn't been particularly kind to the original wiring and I rather doubt that the full voltage is reaching the bulbs anymore. I've ordered a plug in loom for £40 that takes a full power feed from the alternator (itself connected directly to the battery by a nice thick cable) and uses some relays and fuses so that the original cables activate the relays and new cables carry full power to the headlights. I'll see what improvement that makes and then maybe look at some Bi-Xenon HIDs if necessary. They WON'T be blue though Edited March 25, 2015 by eldavo69 Link to comment Share on other sites More sharing options...
