Help us all great one!

Now you've just made yourself look silly by claiming to have been well educated and misspelling anything remotely technical.

I don't know if you actually read that site either.

Slowing the charge through the intercooler may not be as bad as you think, to a point. If the air hurries through, it's not going to be cooled at all.

By the way, you're assuming that the air takes the full '5 metres' to accelerate to 4m/s. I'd be interested to see why your other air accelerates faster.

Yes. You can get more power.

Will you get more power? Maybe not.

If it flows better (tank design, end plates, piping) then you'll get more power. As the turbo will not be robbing as much exhaust energy for the same inlet pressure to the engine, therefore making more power. This is one measure of efficiency.

Also, the inlet air maybe denser (although this is not all that significant usually), depends on how hot the air is entering your engine at the moment. ie. efficiency of an engine depends also on the heat difference between input and output air.

More often you will realise more power (that's a relative more power) by increasing the timing and or boost pressure. (But a cooler can make more power before changing any engine parameters).

If your running stock boost before the new cooler goes on you may gain a little bit of power keeping the boost the same. I was running 10psi with the stock cooler, then I put on a hybrid cooler on, was still running 10psi and the HP difference was huge.

So it depends on how efficient you cooler was at the set boost level to what difference you will see.

      CD009 RB Conversion

      It’s new. It’s the cd009. I did take the transmission apart to mill down the bellhousing and had both housings come off the gears so wondering is something isn’t in right. I am running redline. I can get it in gear running too but it’s just not easier and it’s almost like 2, 4, 6, and reverse all the back gears aren’t happy going in

      Got keys and did a walk around the yard planning the landscaping works with the family that I will be doing Main effort: remove all the woodchip in the gardens that are around (attached) to the outside of the house and replace with 10mm blue metal, having woodchip close to the house is a recipe for inviting white ants, currently there are no white ants within the block and I would like to keep it that way I'll be buying some large raised garden beds to grow veggies and stuff, and the woodchip will be mulched with everything else that gets dug up, pulled out, or cut down during works Next will some minor drainage and landscaping maintenance up one side of the house, where the fuse box, AC, and solar stuff will go, about 12 mtrs long by 2 meters wide, I'll break up the soil, add gypsum and then I'll dig in a French drains about 300mm deep x 300mm wide and fill it with agg pipe and blue metal, then level out the whole area with a 50mm layer of blue metal, the soil, whilst currently pretty compacted, will break up well with the gypsum to aid in drainage, I'll then cover the area with a 50mm layer of more blue metal In saying this, the drainage issue is minor, but that little hidden away area down the side is untidy and weedy, and as all of the main elec stuff is there I want it neat and tidy to appease my OCD Again, the material excavated from the French drains with be added to the garden bed mulch, as will some rose bushes and some other crap looking garden plants, and a old apricot tree that is looking worse for wear The apricot tree is currently in a little roundish garden bed that is in the middle of the back yard with few other crappy looking plants around it, that will all be removed, levelled, re-turfed, and is a perfect spot for a hills hoist There is also a area about 3m x 2m between the rear fence and shed that will get some attention, it looks like some stuff was stored there and the grass is dead, that will also get broken up and mulched, and is a prime spot for a pumpkin patch I've guestimated that I'll need: 3 tonnes of blue metal, 12 meters of agg pipe, 5kg of Gypsum, and a hills hoist, so a few bags of concrete as well to set it in place (the house currently has one of those pull out 4 line jobs, whilst it works, I want a retro old school hills hoist), I am also going to run some chickens, there's a great spot for a coop, so a chicken coop to suit 4 of those lovely egg laying bitches will also be on the job card That should keep me busy for a while, and will finish off the back yard ready for a early spring planting of some veggies and berries  Once the main effort is done I'll start out the front, there's a large rock garden that could use some TLC, but that is only minor works Should be fully moved in within 2 weeks, the landscaping works will start then Fun times, retirement is good

      Steps to DIY sanding car back ready for respray....

      It happens, that's what your single stage filler is used for.  If it is still visible after the 3 coats of 2k primer, it will be visible after the paint is laid down.  Its hard to give 100% perfect advice without being there in person, I'm very tempted to say stop where you are, fill your pin holes with a single stage putty first then keep going.

      New or used transmission? Alignment will be the same with engine running or not. If new, i'm presuming it's a clutch release bearing size issue. If used, are you certain it's a CD009/A and not an older CD008 or less? They had known synchro issues. In my opinion, these transmissions should always be purchased new, they're dirt cheap and you avoid dealing with old revisions.
