Thread: Remaps, Intercoolers, other mods and a dead EGR.

BAS or Alive tune ?

Cool dense air is able to support more fuel bieng burnt which sometimes equates to an increase in power (or a longer power stroke in the case of electronic injection), where as hot air will support quicker and a more thourough (hotter) burn, hence moe power.
There a a lot of variables in the combustion process, but IMO the best thing to do is get the air in and exhaust out with as little restriction as possible.
A good "tuned" exhaust and match-ported intake is the place to start.

I do notice power fade when temperatures get well above 45c and I am in the process off ordering a chip tech intercooler.

BAS. Pete a while ago gave me a very honest reply to what I was asking in a potential tune. He basically did himself out of a sale. The other never replied.
Alive also are a bit to blingy or racy for me. Or that's the way I perceive there marketing.

Perhaps so, after all an engine is just one big compressor. But I'm basically happy with the standard 90Kw, so I wont know myself with the new amount. The tune is basically to knock off the Egr, and perhaps eliminate the immobiliser when travelling.

I have met a guy who claims by simply putting a 4" intake on his Tdi he produces quite a bit more power. We never got around to talking exhausts.
A Tdci runs a 2.75mm exhaust already. In my mind it has enough flow standard. As for mufflers and decat pipes I'm yet to be convinced. Well, more than 5% gain anyway.
I'm a plodder, I love how the Defer just slowly puts along. No rock throwing, no plumes of dust, or scrambling all that is inside. Just plods.

Hmmm interesting

What I am about is efficiency, there are many factor involved. What I want to achieve is more km,s for my litre, I must agree there is not much point going beyond 15 percent larger than turbo outlet diameter. However the mid box is restrictive, the heat which retains is evident. The inlet side of things has quite some scope for improvement, me thinks nugget kit is just the ticket! The factory intercooler built to a price, adequate for European temperate climate, is found somewhat wanting here. I just want to plod on but with lower get,s and going the distance on every litre.
