dyno'd my vr

[Golf Houso]

Pwah purple, asif! Remember glitter paint counts for 10hp as well

With the Adjustable fuel pressure regulator what did you set it to? I know the factory sets it at 3.0 bar, and you can get fixed raided FPR's at anywhere between 3.5 bar and 5.0 bar of pressure.

With a VW Motorsport ECU map, custom exhaust, Pipercross CAI and an adjustable fuel pressure regulator my 1995 VR6 made 119kw atw (averaged across 4 different dynos, all pretty close to each other).

It had 150000km on it at the time and was pretty fit. The FPR made about 6kw difference and the VW Motorsport ECU made about 10kw atw. The CAI and exhaust only made about 4kw combined from a stock 99kw.

So, 90kw for stock for the age and km is in the ballpark. Some mods, better oil and a service will liberate a few more ponies.

Remember with mods (especially a FPR on a VR6) fuel consumption goes up.....

The Red VR6 Ibiza had a fresh stock motor, Pod Filter and Microtech. Did 99.3KW ATW with 17" Wheels. It went heaps faster with 15s but I never put it on the dyno again.

Dont forget the ecu runs some logic about how you drive. If its a city car with a fair bit of stop start it will have been optimised for that. If you want to achieve peak figures you'll need to put some high rpm ks on. Not just a run to the mountains and back. It seems to work out its averages over an extended cycle of hundreds of kilometers.

thats why my vr6 goes so well, hundreds of kms at high rpm not stuck in the city doing little 5kms trips everyday wearing the car out lol.

HIGH K'S OR NO K'S . haha

well atleast you've all made me feel a bit better about dynoing lower than i expected

ya i dont think i'll be messin with the FPR as i feel like stabbing myself in the eye everytime i have the urge to look at the current trips L/100km figure, that these cars so convieniently have.

in a way i wish i didnt live so close to work. its only like 10 minutes frive through neighbourhoods so the engine barely has time to heat up before i get to work. bring on the high fuel consumption and engine wear wohoo!
i'd rather have to wake up half an hour earlier and drive in a straight line at 100kph, than do the 10 minutes of stop start crap i do now. maybe i should move to healsville or something lol

my obsession is looking at the oil temp so I can establish a healthy range to take the revs a little higher hehe .. speaking of which when i sit on the 110km/hr highways my oil temp is in the high 90s or may even reaching low 100's (whilst on an 80km/hr road it sticks around the 90 mark); do most of you guy's have these figures?

my vr6 mostly sits just under the 100 degree mark tootling around town in summer. a little cooler in winter. That is until you get on it. temperatures up in the mid 120s arent hard to attain

[DVR68U]

120's lol thats pretty high , ive only ever seen 110 on mine and that was giving it everything for about 20mins. i think the oil would have started to break down at that sort of temp if you where using a mineral based oil. maybe a syn can handle that ?

your oil temp will have a lot to do with your water temp as it has a oil cooler or warmer in some cases. if you run distilled water and g12 ive seen a drop of nearly 10degress in water temp which can make a 10degress in oil temp change. ( up to a point)

[Tim]

only 110? u arent driving hard enough! Should be making it into the teens at least with a good flog.

[DVR68U]

haha cant go much harder than flat out. i have tried many times to get the pedal to go through the floor but it never happens.

VR6 FPR is actually 4 bar standard .

You shouldnt be playing around with it unless your actually leaning out . Adding extra fuel isnt going to do anything unless you have a healthy spark and more air added which is beyond the scope of the ecu programming .

Adjustable fuel pressure regs generally range from 2.5 bar to almost 7

My oil temp record is 118c on a 42c day out in country wa flogging the absolute pants off it

I run g12 with distilled water and knock-off kamei air intakes, they work very well for a little bit of extra engine cooling!

Sif I'd EVER play with FPR's, etc. I too dont like looking at the L/km figure much either lately
