How much did you get at the glen?

NOS TRADAMUS · Post by **NOS TRADAMUS** » Tue Aug 13, 2002 10:58 am

First dyno at Performance VW i got 66kw on the wheels
Second dyno at the glen 55kw on the wheels

My car really not performing as good as it used to perform, or maybe it's just all in the mind.

I thought at Performance VW your car did 89 kw, cause when I phone them to do it to my car, they said about 87kw, (on dyno) did they mean at the flywheel? ???

That's on the flywheel, but very nippy , last week wednesday me and my buddy who ownes toyota 16v twincam decided to have a go at it each other. From 1st up untill 3rd gear i rule, there on after i sit a car lenght behind him . And he has billet cams, gas flowed head,branches , freeflow,and unichip. ???

I may be wrong but doesn't leaning out mean that through the rev range the air fuel mixture is leaning out? That you are running the correct airfuel mixture for lower revs but not for higher revs. Usually people say the car is running lean?

NOS,

66kW on the wheels sounds good and correct as my Polo 1600 Mp9 also did that before the mods with only the cone filter.

So i think you shouldnt bother yourself too much with the 55 at the glen.

Dont feel bad either boet , cos its all in the mind and not all dynos are the same.

How can the guy tell you that the car was leaning out when he didn't even put a C.O probe into the exhaust.

And if it was the guy doing the runs , i wouldn't take for granted what he said, IMHO he din't know the first thing about a dyno and how to run a car on a dyno... ???

Well taking into consideration what Gassed said... If he didn't have a CO meter then he was assuming and assumption is the mother of all ******. If you are worried take it back to Performance VW and have them do a dyno run for you.

Leaning out means that you are not getting enuff fuel through on top,your air mixture is too high and fuel too low.
As gassed said, yes this guy probably does not know what his talking about seeing the he did not have the CO metre hooked up to your car..
Question to you is,does your car surge on topend, does it feel like its holding back?

Howzit gambit,

Not actually car seems fine does'nt seem like it's holding back . Yep that oke at the dyno day was probably speaking through his ass.

Thanx gambit just wanted to find out what this monkey was speaking about.
