No, I think it's a reasonable one based on a) the factory specs of the base Carrera and the S and b) your specific mods.

 

Heh, a serious one for a change. It`s from mustang dyno, 1.1593 less from dynojet. that`s sort of the whole point of dyno bashing and that dilemma how to compare apples to apples. But it`s fun nevertheless.

Stock C2S from mustang shows somewhat in low 280hp area, samples can be found easily. even on this very forum.

I`ll wrap this up anyway, as I care much less about all this than most of folks who reply to this thread like I am attacking their holy cow.

 

I see. Didn't realize it was a Mustang dyno run. I'm a bit skeptical about the equations between the two dyno types. Also, don't know if that comparison Cab used 93 octane or not so best comparison would be to get a 997S on the same dyno you used. But one thing is certain, your mods gave you gains and that is most important here.

 

'Low-end mods', right.

Did not spray golden dust on em, did I?

 

It`s all about feeling better in the end anyway. Who cares what those numbers are...

From any practical standpoint conversion factor between mustang and dynojet should not be a simple multiplication but I believe for most practical reasons x1.15 getting used by everybody out there. Who cares, anyway...

All that is just fun, real difference will be after supercharger install, if miracle will not happen in next 2 years that will allow me to buy a 997 turbo.

 

Right. There's an old C&D article where Steve Dinan showed how he could get from around 300 to over 400 hp from the same car, on a Mustang dyno, just by varying how the tests were done and whether or not a fan was used. In the case of the test that was linked, there was no fan, for example. Steve Dinan's article showed how the engine management software compensates for the lack of airflow when no fan is used and how the power output (and thus the dyno result) suffers as a consequence. Either way, it always seems kind of meaningless to attempt to compare different tests done on different days by different people...

 

Pointless conversation anyway with this 'guilty until proven innocent' approach but fans were placed in same exact way around the car and it was strapped in the same way, so, with all respect to S.Dinan - it got nothing to do with my graphs.

During first pulls first pull was done without fan blowing into open engine compartment, only with 3 fans in front and it shows max HP at 258 horses. Then dyno shop owner came by and corrected setup with opening engine compartment and placing fan blowing into it then we got that 268 reading, next came at 261.
And again, tuned results came as 289, 283,283. Those two last pulls graphs match exactly one into one both HP and torque.

 

the more pics I see the more I like your car... great choice, blk on blk with the yellow brakes is drop dead... very very nice choice... gotta wear a bullet proof vest in this thread jeezus

 

nah, just learn how to dodge bullets.

 

Well, I think it really prove Steve Dinan's point, because the dyno pull you linked for the 2006 S clearly confirms that those specific tests were run without any fans at all... On this basis, one has to assume that the reported numbers for that 2006 S would probably have been higher had the tests been run, with fans, in the same manner as yours. Either way, I'm not trying to undermine the fine work you've done on your car, more pointing out that it's a very inexact science and very tough to draw reliable conclusions. The only one that matters is whether you're happy with your results and the improvements that you feel - and I'm sure that you are.

 

I have to agree that there is something going on with this Dyno test, a 21-22% loss of power from OEM spec crank HP to the test wheel HP is way higher then I have seen, but as mentioned by others what do the numbers really mean? Does the piece of paper make your car go faster or slower?

If any one wants an 8 1/2 x 11 paper mod let me know, I have lots and will be willing to do a group by at $2 a sheet

 

What good will it be coming from a person who does not believe into miracle of IPD Plenum?

 

Common, the dyno sheets don't lie. This mod will not give you any extra power, no faster on the track, and it is pretty easy on the pocket book. Can I sign you up for two? You can use this plot your own charts, and for an extra $5 I will included a red or blue pen!

 

No blue pen mod would work as expected in unworthy hands of plenum non-believer!


OK, enough is enough, I close this stuff up. Not more responses here, please.

 

So I take that as a no, I would have thought that with some of the other mods that you have you wouldn't mind this one too!
