Dyno results.

[jhoke]

Did 3 pulls yesterday on a DynoJet.Bone stock.1st pull 234.8 hp and 227.5 Torque2nd pull 235.7 hp and 227.6 torque3rd pull 238.7 hp and 230.2 torque

Air fuel ratio was perfect.

Mods go on Thursday and next week will re-dyno. I guessing no more than 10 addtional hp with z tube, y pipe and 5/16 Motordyne spacer.

[NSR240sxe]

Awesome! Can't wait to hear the results once the mods go on. congrats

[RED_DET]

What year and sedan or coupe?

[jhoke]

2003 Coupe, 6MT.Installed the goodies today. Stillen z tube, Stillen y pipe, and MotorDyne 5/16 spacer. Butt dyno tells me it feels like it pulls easier, like it is breathing easier, but that may be because my wallet wants that to be the case. Dyno again next week, Tuesday or Wednesday.Wonder how many hp the clear corners added?

It is breathing easier, it is not your imagination or wallet talking. Not a power rush, but definitely a better response.

Do yourself a favor and get the grounding kit!!!

I'm still confused as to how this helps with HP???

[G_whizz]

You did the popcharger or other intake right? Not just the Ztube. Just curious because I'm REALLY curious to see those dyno results!

[jhoke]

No intake. I haven't found one that I believe will perform any better than the stock in bringing in cooler air which is the point after all. Tests were done on the BMW I had and it was found that in many applications just removing anything in the airbox which disrupted the flow was just as beneficial as a CAI. The z tube should have smoothed the air flow. This isn't to say that at some future point a CAI will be done.

[The_Scooch]

So what happened with the dyno results?

[jhoke]

Haven't been able to get it scheduled. Hopefully the first part of next week.

It really doesn't, but it gives the electricity a more pure path to travel, which in turn allows the elecronic signals to transmit quicker. This results in a bit quicker throttle response, less shift lag.... basically anything that is governed by electricity, or computer works just a little better. (which is really pretty much everything in the car!).

[Q45tech]

Electric signals travel at ~186,0000 miles per second just like radio waves [same thing actually]..............0.1 millisecs is the smallest resolution of any sensor............signals could travel 18.6 miles of wire in that time period?

"the electricity a more pure path to travel, which in turn allows the elecronic signals to transmit quicker". ????????????

Nothing in a wire can make the signal slow down or speed up!

Grounding kits say they work because the body resistance may not be PERFECT at some common ground points. Resistance only affects things IF THE CURRENT FLOW IS HIGH then they create a small voltage drop.

Sometimes there are problems with paint or corrosion getting between the lug and the bolt on the body [needs cleaning].

Ok, well, you got me there. The changes in performance were all in my mind.

Not necessarily, some factory grounds could be marginal, as mentioned, or due to the number of different systems, the location of various grounding points might make a difference. Trying to qualify what is actually the 'difference' is a real problem.With some control electronics running at very low potentials, parasitic voltages can be a problem too And there is a difference between logic and analog grounding.Grounding is not a simple idea as many think. Major corporations spend a lot of money on designing grounding systems for sophisitcated communicaiton and computer equipment. The car is hardly at the same level of complexity,but some things might still apply.

Maybe the 'grounding kits' are a shotgun approach and actually make some subtle improvements along the way.

[jhoke]

My dyno guy got back from the SCCA regionals today. Hope to get the new dyno results by Sunday. Been very hard to wait. Very curious.

I can get on board with that. It makes perfect sense...

I just have a problem with people who take a statement and FLAME it because they know more. The statement I made was obviously not made from a position of knowledge of current, electricity, resistance, etc. It was a statement made on, what I considered to be, logical assumptions. I'll take ownership of that level of my own ignorance... however, there is a better way to correct someone other than to start a brush fire. Q45tech is likely a great guy. I guess I just took his approach to teaching me something about electricity a bit personal.

Just my two pennies.

I would have to disagree, different types of wire will give the signal an ability to travel quicker. Silver is the most conductive, but the quickest to corrode, gold is the second most conductive, and is slow to corrode, which is why most of you computer connections are made of gold. Just my .02 cents.

[psedog]

Lets not forget about the people that are running hi powered sound systems. An upgraded wire kit will help out big time in this citation. The stock 8gauge wires normally can't keep up, especially when you are running higher RPM's. If you have upgraded your sound system and you don't upgrade the Big three, then you are looking for trouble. I like to see someone do a Dyno with a bass track running and then without one, on a stock ground vs. an upgraded. I haven't but I have felt the power difference.

[jhoke]

Finally got the re-dyno scheduled for tomorrow morning. Let you know what the mods did to numbers.

[jhoke]

Did 3 pulls yesterday on a DynoJet.Bone stock.1st pull 234.8 hp and 227.5 Torque2nd pull 235.7 hp and 227.6 torque3rd pull 238.7 hp and 230.2 torque

Air fuel ratio was perfect.

Mods go on Thursday and next week will re-dyno. I guessing no more than 10 addtional hp with z tube, y pipe and 5/16 Motordyne spacer.

Best 2 of 3 pulls after mods.

243.5 hp and 232.5 torque 244.0 hp and 233.6 torque

Dyno results of stock setup was increased 2% by the dyno software according to ASE standards for temp. etc. and today the results were decreased by 1%.

Conductance might be appropriate in discussing audio [an AC signal] however all the sensors on an engine are just DC voltages or pulsed DC signals.

Conductance is the reciprocal of the DC Resistance term.http://en.wikipedia.org/wiki/E...tance

Signals always travel the same SPEED thru a wire whether copper, silver, gold, or Plutonium. Signals actually do travel slower thru a fiber optic than thru a piece of wire of the same length. As Photons are different from electrons the refractory index of fiber.

Don't confuse resistance conductance with speed of electron cloud transference from one atom to another.

An electron is an electron, they are not different in different materials.

A bad connection [corrosion] in a terminal or connector can reduce the level of the signal but it cannot delay the signal nor magically speed it up.Unfortunately most cars are made of steel and copper is a reasonable ;ow resistance cost effective wire to use for these simple signals.
