3.2 First Impressions

Wow, they all sound so different. Of course Ben's car is running with a fairly large handbrake at the moment. It would be good to get a comprehensive test done of their relative characteristics. In gear acceleration etc. Can't wait to see the video of you all storming around the track at full noise though.[:)]
Oh, and thanks Paul for posting those pics. I did indeed miss them and will answer a few questions on that thread. Can't wait to get back on the track myself.
 
I have some universal ducts from demon tweeks that just fit either side of the rad in the lower grills. I have also discovered that metalised tube from VW beetle heaters is available from eurocarparts for a couple of quid. Not yet discovered whether this fits onto the ducts but should be close, this is easily formed into an oval for more clearance, whilst the pipe I used before was too close for high mileage use so I cut it back and aimed it in the general direction of the standard deflector.

I reckon you can provide all the ducting you like however if you have big power and tiddly brakes no amount of ducting will help the massive increase in heat caused by higher speeds into corners. Bigger brakes first........... then ducting if you need to help cool the inside is my advice.

Part of the Silver Rose forged wheels design is to help direct air into the wheel centre, not sure about the D90`s.

 
Sorry for the lack of posts I've been re-discovering the simple joy of driving this weekend. I must admit it's just absolute bliss, driving about for hours in the sun, playing with other cars, laughing at the sounds of huge spits and backfires with no particular destination and just a little sideways slithering out of the tight bends at under 60 in third[:)]

Car is running beautifully and just gets better and better every time I go out. The sound has changed too, it now does a lot more cracking and popping as it returns to idle and a bit more audiable fluttering from the diverter valve. Sounds lovely with the windows down and the roof off. I've also confirmed that there is truth in the rumour 'German cars just need to be driven' after a good old Italian tune up all the squeaks and stiffness it had from all its time sitting idle have gone and the fuel guage which wasn't working properly now reads full when full like it should.[:)][:)]

Mind you the miles are taking a long time to go now[&:] Im at 710miles now 300 to go!

Regards,

Ben

p.s. Had a lovely short run in with a Cayman S, nice to see one being driven properly as many never are! Does anyone know what the figures are for them? It was very nippy but easily dispatched once on boost, even changing lightly early at 4500 just to be safe![;)]
 
hi ben glad you are enjoying you car..... i have decided to sell the cab so if you no anyone who wants the most powerfull 2.5 in the country let me no............nick 07766107605
 
Sell the cab! Noooooo why? You finally have the power?? What will you get that could compare now? However I would be very interested if you were interested in a wheel swap? I REALLY need some wider wheels and those black wheels would suit my car beautifully! Drop me an email if you would consider it?

As for George well... since you asked so nicely [:D] I'm over 1500miles now, I've been using the advice of Dfastest951 (from the Rennlist) and doing an extended run in period ..if nothing else just because it makes me feel safer. Its only been over 5000rpm's a small no. of times thus far and we're still on super low low boost. "¦For now!

I've been through the new engine panic crisis twice so far. First time was when I saw a cloud of smoke on start-up (having never emitted so much as a molecule before this time) then found oil all over the back of my engine and noticed that the oil level which hadn't moved previously had dropped on the dipstick! Rang Jon only to find out that the same thing happened to Paul a year ago. Jon had filled the oil up to the max on the dipstick for running in but because the dipstick is for a 2.5sump and the sump is a 3.0 its actually too short so the oil was over filled by about 15-20mm. As a consequence the first time I started holding the revs to 5k it pulled a load of oil through my breather system and as I have no catch can it just spat it out over the nice clean engine! I'm very happy to say that now the engine has ejected the extra oil it is still not using a micron of oil and is lovely and clean.

My second and more recent sleepless night was when I found coolant in the recess between the block and the balance shafts! It looked as if it was leaking out between the head and the block and my mind was going through a million and one horror scenarios about how I was going to get to work, was it really a sensible daily driver and how could it be solved!! But thank god the leak has now been traced to a slightly loose clip on the coolant hose that enters the top of the head. Phew!

You hear and see so many horror stories with re-built and modified engines that I suppose everyone is probably this jumpy when putting the first few miles on a major re-build but I'm very pleasant to report that Simon and Jon have really done their homework on this engine and none of my worries have had any substance.

The car starts and runs smoother than when it left the factory in 85'and sounds fantastic on boost which is the one area the standard 944 always lacked slightly. Whilst mine sounds different to Paul's car because of the different turbo, it still has that pure aggression full bodied war cry when the turbo gets spinning! Unfortunately with the weather at the moment it's not very often I get to hear this because it will easily spin the wheels in any gear ever before it gets into full stride but it's a fabulously flexible car that will easily get you around smoothly and quietly at speeds which could get you into a lot of trouble without ever even bothering the turbo which sits around the atmospheric pressure mark just assisting the engine from almost zero revs giving the impression that the car has no lag.

Now all that remains is to feel the cars full fury as it gets its proper wastegate and boost pressure installed and set up in maybe a couple of weeks time! Should be pretty fierce![:)][:D][:D]

Regards,

Ben

p.s. I would love to hear how 333's 3.0 is going now? Looks stunning on the track. Hope its living up to expectations.
 
Hi Ben,
Glad to hear they were nothing but scares. I know what a scare can turn into when it becomes a concern so nice to hear you survived unscathed. Unfortunately I have had another hiccup and have decided to wait until we have all the remaining mods together and do it all at once at the dyno rather than keep adding and subtracting components along the way. So consequently I'm off the road yet again so you'll have to wait for a while longer until I can get some track footage of my little 3.0L. I was meant to be at the track last Saturday for the first sprint of our season. I was looking very much forward to this as I had missed the entire season last year due to ongoing problems. Anyway I missed it again but managed to take a little bit of video of my friend and mechanic in his 1986 2.5L with Vitesse stage 3 kit and 3" exhaust. This is on one of only 2 tracks we have throughout the entire city of Sydney Population over 5 million. It is going to be redeveloped at the end of this year and this is on the shortened version of the circuit. Hopefully in a few months I will be able to link you to my car as well.

Oh PS, do you know if Jon or Simon have done any modifications to your sump re oil baffling or the like?
