Thought I'd start a thread to cover the car's development.

Just booked my rolling road/dyno session for this Wednesday, to get a baseline for the car's engine performance, ahead of tuning. Results posted that evening.


I am chomping at the bit to get going with the car

Nice one. Make sure you put RON99 in it

Just back from Surrey Rolling Road.


Results below, which I think are consistent with the Litchfield car, which ran on the same type of dyno at Ecutek.


Car running V Power 98

Flywheel, wheels and flywheel?

What was vixpy's opinion, much to come?

yep


Not sure; it's his first one. Obviously it would be useful to have a range of results across this and other dynos


Might give a bit more and yes, runs pretty rich.


frankly it needs a mahoose turbo

Yes sorry you are correct might say 200 on the tin but in real life more like 175


False Advertising maybe??

Dynos are better as a comparative tool, for example, to show uptick from tuning etc, which is why I took this baseline.


Different types of dyno will also give different results.


My car doesn't feel like it is short on power, although it might give a bit more as it loosens up.

I think its wheel horsepower. You get abotu 15% power loss throguh the drivechain.

In the states they were getting between 160-170 wheel HP.

GOlf GTIs generally return their rated HP at the wheels and close to 250HP at the fly:



This could be the reason the 0-60 time are similar dispite the GTI being heavier than a GT86

Nope. OP confirmed the graphs were in the sequence I listed.


Absolute numbers are for willy-waving only. It's really so you can compare before & after figures.

Dyno Dynamics, dynometer, etc? They all give different results which will vary by fuel, temperature, humidity, operator, etc.
