Very plesaed! The car hasn't been tuned since the Vortech was fitted.

Here's my run - http://www.stephengrant.com/350z/video/dynoday.wmv

and here's the dyno...

 

Wow, that is untuned whp? If so, that has to be some kind of out of the box record. What was your A/F like?

 

Very rich - up to 5000 revs it was around the 14 - 15 mark. After that, it was off the gauge!

Don't forget in the UK the car starts with a bit more power and that we can use 99 octane fuel.

EDIT - just saw what you asked. Yes, is untuned, but no, this is crank hp, not whp. I'm still pleased though

 

If that is not tuned then it is about 20 RWHP higher than the ave stock Vortech dynos. Also what kind of dyno was that on? Does that dyno show higher numbers than a Dynojet? We need to see a dyno before the Vortech install.

 

Ok now it makes more sence. Enjoy you car.

 

Stop driving that thing hard, 14-15:1 is VERY LEAN for FI!! BTW I thoguht that might by crank hp, still decent, but sounds to me like you really need a tune bad. You went off the chart lean !?!

 

That's LEAN not rich, get it tuned quick or don't go over 4k unless you'd like to blow your motor

 

off the gauge, as in off the gauge rich.

I'm aiming for 12-13 so I can't see why you think 14-15 is too lean??? What have I misunderstood ... ?

 

you are misunderstanding which numbers are lean and which are rich. high AF is lean. you want it much lower than where it is now

 

!!!

Well, I drive it very lightly (with the exception of the dyno yesterday) so I won't have hurt it normally, but thanks * 1000 for letting me know!

I'm new to FI. Can you tell?

 

Lay off the throttle...your engine will fail soon otherwise. Get the car tuned asap!! You are waaay to lean. You need to be less than 12:1 to be safe on a FI car...preferrably around 11:1..

 

Suspect the A/F ratio is not valid.. The A/F for Vortech out of the box has been rich!!

 

Strongly suggest you get a wideband A/F gauge installed immediately to monitor your A/F.

 

I have. I have the AEM UEGO unit

 

Do you have a graph or read out of your A/F ? If so , post it please .

 

Nope. It would be slightly pointless anyway as the car is *not tuned* - I'm currently only monitoring it to make sure the car is not in a dangerous situation. However, the part that is making incorrect readings is not the gauge - it's the driver!!!

 

by the way..

Our 93 octane is the equivalent to the European Super Unleaded..

the octane units and the way it's measured are different. So your fuel would be probably 93 octane if it were converted to RON US equivalent. You can search for the formula to find out the conversion, I don't know it.

Anyway, just mentioning this so you don't trust the fuel to be a buffer for any tuning issues you have. High octane won't solve your AF ratio problems, it would help with timing to make more power but not AF ratios.

 

OK - I didn't know that - and am somewhat sceptical seeing as many European cars have higher manufacturer stated BHP as they are tuned to the higher octane fuel. If the octanes were identical this wouldn't be the case. Unless it's an emissions issue?

 

Stephen careful or you 2nd hand Vortech is gonna explode on you

LOL so now stop bragging on the Uk forum and drive below 4000 rpm or get it tuned lmaooooooooooo

 

Pfff Val

Just checked with the tuners and that's all fine... the AFM reading of 14/15 is on idle. Under load it sits around 11/12 which is where it should be - I gave the impression that it was at 14/15 on load, which of course is not the case!

So I'm back to being a happy bunny
