Went To Wsid,not Happy!

Totally agree with Dr Z and drop the humuduty idea it's an absolute red-herring.  No humidity would not have a discenable imact on the performance of your engine and advice like oxygen doesn't burn and humidity has a greater impact on the turbo's performance than intake air temperature and quite wrong. 

A trip to you know who in Melbourne will get you on the right track and put a smile back on your dial.

Without punctuation it is difficult to know exactly what it is you're trying to say in your post.

However that piece I highlighted is quite clearly stated and seems to be directed at something I posted. (I don't think anyone else raised the point).

It was not "advice" - it was a clear and accurate statement of fact. Oxygen DOES NOT burn. There it is again for you - please read it slowly and let it sink in because it IS an indisputable FACT - NOT my "opinion" or "advice".

I think I agree with the gist of everything else you posted (if my interpretation of your post is correct).

okay - I will a little (light heartedly)

Just for the record - pure hydrogen DOES NOT burn either - needs something like oxygen to react with... That is a fact!

One could argue that the most common element to be combined with others in most combustion we normally would use is oxygen - so one could argue that it does in fact 'burn' although it is not the energy source, just the element reducing it...

Anyway - hope you don't mind a little stir...

A little stir is all good fun Ben but sometimes facts are just facts.

FACT - Oxygen DOES NOT burn. I don't care what spin you put on it the fact remains. Oxygen is as you say the medium which allows the chemical change (burning) to take place. The exact same number of oxygen molecules pass out the exhaust as which enter the combustion chamber. It's just the composition that changes.

FACT - Hydrogen DOES burn. Have you looked at the sun lately. Well I hope not actually, but you get what I mean? The sun is simply exploding hydrogen gas - exploding because it is above the ignition point of hydrogen which is something like 550 degrees C

Sorry to boor everyone with basic scientific facts but some knowledge of these things goes a little way to understanding the output of our engines and what influences may effect that production of power.

It was mentioned a couple of times that high humidity causes a drop off in power and results in slower SS400 times. I am simply trying to understand how this is so - I'm not saying it isn't, but questioning the thought processes and waiting for someone to give me a better understanding based on physical evidence as to why it is so. My knowledge and experience goes back to classroom physics only and I have little drag racing experience or knowledge to help me get my head around it.

So what I can gather is, your querying as to why high humidity slows a car down, since the more moisture in the air means greater the level of hydrogen which is the combustable agent along with the fuel, so higher humidity should equal more power.... Theoretically.

.....crikey - don't tell me you really believe this stuff do you?...given the opportunity I'll get you down to our research labs in Melbourne for a reality check.

Dyno gragh with torque and power..the 164.9 was standard.Had dramas with EBC.Other one is boost..

On a dyno day we had at RXE the stockies ran between 190-205rwkw.

Check all turbo & manifold bolts, all hoses (the cross over will fold into pipe under were you can't see) & plug gap. Every time this check has been done even 2 days after a ford service more the 1 fault was found.

Get to know your own car do it yourself.

No...

Will start a new thread on this this afternoon when I have some time...

hi guy's I will just add a bit here,

I have run in a lot of hot weather,

was stock, my best was 13.9@101

but with heat soak, it ran as bad as 15.2 90.5mph.

with exede only, it ran a best of 13.2 @107mph

but with heat soak, and on a hot day, it ran as bad as 14.6 101mph

even when I ran my 11.7 114 mph, I did a 12.5 @ 108mph

the car can get a lot more heat soak @ the drags, then driving around the street.

I have bubled the paint on my crossover at the drags just from heat soak.

so just don't blame the tunner,

at this power level I don't think the torque limits would be causing to much trouble.

even with the GT we ran at the drags the other day, it ran a 12.9 @ 107.8

but it also ran a worst of 13 .5 @103mph from heat soak on the same night.

you would be happy to run .6 of a sec off your time, and I beleive you can when you do every thing right.

I have seen a xr6t (stock) and a new driver, run a 14.8 @94 mph,

then cooled the car and he ran a 13.9 @101mph on the same night

and on another night pulled a13.8 @ 102mph.

the other thing you should do is make sure you have more then half a tank of fuel

and also make sure your fuel is at least as good as the fuel it was tuned on, I think it is worth running a bit of octane boost, just in case you get bad fuel when you fill up. if your fuel is bad, it will cause the car to pull timming out, and this will efect you the most at max torque.

How long a gap should you give to help the car cool down.I did a 14.08 at 6.26pm and didint have my next run till 8pm which was 14.13..In between those runs I sprayed the cooler and piping with ice water and had the bonnet up for a fair while..The first 2 runs were only 28min apart and they were my best 2 times..

who is it?

<{POST_SNAPBACK}>

I bet its Intune?

<{POST_SNAPBACK}>

I had my car dynoed at my new Tuner, it measured 250RWKW, the original tune was done at intune 1 year ago and intune said I had 266RWKW, my new tuner was not impressed with the tune, boost comes on too strong and the A/F are not the best, he said it was lean. I have since fitted and intercooler and hi-flow CAT and waiting for a time to get it on the dyno as he is booked out, so till then I’m driving it easy. My best time on Gtech was 13.3 with my 250/266RWKW. I'm not sure if Intune has improved in a year but im not going back.

[ford number 1]

Who is your new tuner FREEDY??

[TBO240]

like geea says you can stuff up the launch and get a bad time but the mph should still be there and it isnt,I ran 14.1@100mph stock(186rwkws)you have a problem somewhere and I dont think it is your driving.
