Standard VR6 engine figures ?????

[George-1982 0]

Hiya'll

I took part in a local rolling road event yesterday with the local Club GTi (newport) crowd, was an awesome day and I was pleased with my run - I think !

I'm after a bit of translating the figures in relation to what my car should've been as standard :

My car - '92 AAA Engine code, Ram air induction, scorpion stainless exhaust, everything else stock.

The figures were all done in fourth gear :

190.0 BHP accord to DIN 70020

180.0 BHP - Engine Output

139.5 BHP @ the wheels

Drag = 40.5 BHP

Torque = 243 Nm

Max @ 115 mph, 5970 rpm

Air pressure - 999 mbar

Intake air = 4500 mbar

Optinal Pressure = 12600 mbar

Air temp = 45oC

How would this compare to standard (m) Excuse my ignorance but I'm just getting into the VR6 scene.

All comments appreciated.

George.

Hi mate

Not sure about bhp at the wheels but at the flywheel (which can vary from rolling road to rolling road - depending on how they calculate the transmission losses) the bhp on a standard VR6 manufactured up to mid 1995 has around 174bhp. From mid 1995 onwards (OBD2) golf VR6's have around the 185bhp mark standard as the ECU and throttle bodies are different. Not sure on torque figures as standard though.

If your engine is making 180bhp at the flywheel for an OBD1 vr6 then that is pretty good - 5bhp increase sounds about right for the mods you have. Not sure what 243NM torque is in ft/lbs.

What is the DIN 70020? If that was the figure for the flywheel then 190 bhp for an OBD1 vr is very good! Most OBD1 golfs will make OBD2 power with a larger throttle body butterfly and chip/remap no problem.

Sounds about right.

the DIN 70020 figure of 190 has been corrected to meet the DIN standard. this is power at set constants - namley air temp and pressure.

Seems to have been a hot day yesterday as measured air temp yesterday at 45 degrees c!!, so with this corrected back to denser air at 20 degrees you figures gone up.

Ignore it, it means nothing

139.5 at the wheels is the only figure that really means anything. They have meausured the drag of the transmisison and added it on to give flywheel power - its not gonna be 100% correct but seems about right

So, 180 bhp.

243NM is 179.2 lb/ft.

Standard VR should be 174bhp and 173lb/ft.

Good result that.
