u couldnt help me out with what piping i need for the evo fmic? cheers I'm in the rather lucky position of being able to get custom piping made on site, but I can take some pics whenever I get the chance if that helps any. Freddan the injectors are actually usually used on VAG cars, and yes still on standard internals. I'm using a Helix paddle clutch, four point.

not really - at lower boost levels, my power is still climbing as I hit the limiter at 7,200rpm. I could have easily set it to 7,500, but I wanted to play safe. Any 20VT with forged and balanced internals will be good for over 7k rpm without drama. Its also great fun to still be pulling really hard as the rev limiter hits - most turbo cars are well past their best by then

That's the interesting bit.

Yes the standard head is probably at its limit, as are my 440cc injectors but the 044 fuel pump is helping a great deal. The BHP won't kill it, but near on 380 lb/ft of torque will...if I could get it out of 10.5 afr as she comes on boost hard I dare say there is 400 lb/ft available. Matt, the rev limit is interesting - I was just playing around with it tonight, but as you can see from my graphs there is little need to go above 6.5k at the moment. Animal is the only way I can describe it on the road. It's all in the block.

Maybe if you run a few layers of tape round the block it'll help it hold together. At the very least, it'll help to catch the rods when they decide to make their escape.

He He, nice one Matty. That is a seriously good torque curve So where is all this extra power coming from then... surely your not just turning the boost up I think it could well be referred to as 'fine tuning' Some pretty mean figures coming from that coop though Matty - nice one! I think my de-cat might have you scared this weekend though, I might make another 5HP!!! Wowza

It's that Scottish air... gives you at least 50bhp more.

But more importantly.. COLDER! I heard on the grapevine that AEM are bringing out a SAFR meter in the new year.. (Scottish Air Fuel Ratio).

anyone want to RR their car in the south and then in the north on an identical dyno with the same operator to see if there is any difference?

it will be interesting to see how the rods hold out - I bent one of my standard rods at about 350lb-ft It sounded just like a sticky tappet - clicking noise at tickover, at exactly half engine speed - turned out it was the piston rocking in the bore on the exhaust stroke as the small end was slightly bent Isn't thre one of our Scandinavian friends running over 400bhp on stock internals? What on earth is holding these engines together?

I think sparco (before he changed his name to cheasy peas or something like that) is as well IIRC, obviously some can take it and some cant.

Well - it's not a matter of whether they can take it or not, but rather how long they can take it for. On a well mapped car the pistons may last a while. On a poorly mapped one about 5 mins. Over 350 lbs / ft we KNOW that standard rods will bend, though there will be slight variences depending on the set of rods that happen to be in the engine. Any slight manufacturing defect and guess what's going to happen.
