dyno'd my vr

[tassie_euro_mk1]

Whoa..I didn't know the 128 was at the fly! Damnit why do our VR6's keep sounding less good?! I should just go buy a corolla, it'll chew up half the fuel and still compete hahaha

Blasphemy!!!

We still have fun in our VR's dont we? When we have fun does the KW output really matter

It is good to know what other VR6's out here are putting out tho. I plan to stick mine on the dyno hopefully next week sometime when the new air flow sensor is in.

It just a curiosity thing for myself

Exactly. 90wkW is not so bad anyway. A 2.0 16v Mk3 is around 80-85 and they're rated at 110kW at the flywheel.

I would say your figure is about spot on - there're plenty of other muppets crowing about high figures and their cars absolutely suck. One of our hot-n-cold customers here had his car 'tuned' by a local workshop and came back crowing about 285kW at the wheels (with a dyno sheet to prove it): the car is a 2003 Corolla with a T25 turbo (yes, a circa 160kW turbo!!) and stock injectors, plus one in the throttle body - also setup by his mate at the other workshop, who believed he had done an awesome job

This is just one example of dodgy dynos, but I could go on forever, so if your car drives well and you like it, who really cares

I've never placed much stock in dyno figures either,good to check improvements in hp when you make mods etc but it's what you feel in the seat of your pants that makes it fun

[Peter Jones]

, so if your car drives well and you like it, who really cares

That's my philosophy right there! I see dynos as a tuning and dianostic aid, not some sort of recreational pastime.

i saw that video from vwvortex australia, where they had a dyno shootout and this first car was a stock vr, and it made 98kW. thats why it confused me thats all.

Hey, that was my car! The day was quite hot, around 30 degrees or so. I was disappointed at not getting over 100kW at the wheels.



However, my engine is pretty young, being replaced when the previous owner smacked the sump, bent the oil pick-up and the res it history. At the time, the engine had about 80,000 km on it as opposed to the 180,000 km on the odo. Also, I was running 98 octane 10% ethanol blend, and I have a K&N panel filter.

you said u had a pod filter in another thread yeah? maybe try getting back on the dyno with a stock airbox. we could finish that debate once and for all!

[Oneofthegreats]

I said to myself, I would stay out of these power loss/dyno thread's, but I've got to say, try it with an honest 30% drivetrain loss.

Work's out to be 161hp at the engine. I reckon that's not too bad at all.

I ran a very loose GTI engine with a Audi throttle body, matched ported intake & made 66atwkw's. 30% loss. 88kw's at the engine = 117hp. Spot on.
For interest sake they made 112hp stock.

I do agree with how fun the car is. Yeah corolla's are about as popular as strands of hair on my head, so it won't be as cool or fun. And, it may be a bit dissappointing having to wait for the power to surge through in the VR, but when it comes on it really comes on....so that's fun


I was just surprised to hear our supposed 128kW was at the fly! All I can say is....whoops!

Firstly be glad you don't drive a 2.slow ... Secondly those 'rollas aren't really that fast, in some cases even slower than a 2.slow as I have discovered. That goes for pretty much any other 4cyl honda that isn't a decent V-tec motor as well.

[brendan_lfc]

are we talking about corolla sportivos or just normal corollas? haha..

[Mrk_Mickey]

I'm talking about sportivo's, blacktops, my mate's sx (pulls bout 75kW he says, it goes pretty hard!) anything like that

[Golf Houso]

are we talking about corolla sportivos or just normal corollas? haha..

Both, not the newer ones of course 20v's included, even V-tec yo! integra GSi's have felt the wrath of the incorrectly timed 2.slow ! Although I did get utterly smashed by an 1986 EXA once, that was bad...

Those rolla's and civics are honestly slugs up until 6,000rpm, and I also discovered that fancy airbrushing doesn't contribute much to performance either

[Mrk_Mickey]

Nah bro what you talkin' bout yo? Red R's increase horsepower by 10% we all know that!

You should have seen this guy with a PURPLE R....he chomped!!!

[gti vr6]

I think those figures are about right for your car. Did he mention the fueling?

I just dynod my car and it is about 50hp shy of what it should be due to it leaning out when it comes on boost. I was gutted at first but then realised that I still have more left in it.

Like someone said earlier all dynos read differently. You could run it on another one and get more. You will loose 25-30% through the drive train.

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.....
