Yep, 6-8 hours was I got quoted on Tuesday from a guy that's worked on soarers before. He recons it's a prick of a job because there's not much room to work with.
7-8 hours at $70 and hour and the installation costs as much as the headers. Then another $900 for 2xLukey Race magnum mufflers, 2x 3" resonators and an X pipe installed.

Well, I've already got the exhaust and mufflers and high flow cats, he'll just have to cut the cats out and move them down and fit the headers, but I can see getting the headers in being a prick of a job

Regarding unichip installation is it best to have your ecu reset done before? or have it in non reset mode, if you no what I mean. Just thinking if you just done your reset and the car is pretty lively, less to adjust timing/fuel wise? as compared to when they feel sluggish. wanting to get a chip on an 8 and deciding how to set the car up before its tuned.

It was not complexity as such but rather the improbability that Benny (in this example) could quote his injector duty cycle and brake specific fuel consumption whereas I had inferred from Benny's post that he was after a quick and dirty approximation, not something to research on the dyno. Therefore, the response, however sound, seemed amusingly inappropriate. That is all.
You can use a multimeter to check the injector duty cycle but you'd need to be on a dyno... The BSFC is a value that is usually guessed according to the engine characteristics like if its NA or turbo, type of cylinder head, age of engine/design etc.. Then you simply plug it into a high school physics style formulas and you get a reasonably good guestimate/answer. You'd need to go into a lot of detail to get the exact answer, but this has served just about anyone who has modified a petrol engine at some point.
I'm still confused. Jason said it’s the complexity; you smiled, then said later it’s not the complexity. But anyway, I don't give a if only one person finds what I wrote useful then it wasn't completely inappropriate.

Chuck in a throwaway line and you wind up in detailed explanations .
OK, here goes: My crack was at the comparative lack of value of indulging in a formula based on
measurements which had not been taken
requiring independent equipment (a dyno, and a multimeter capable of measuring duty cycle, e.g. a Fluke 87-5 for about $750)
with another estimated value
as being effort overkill to produce a doubtful number when all the above is compared with what appeared to be a fairly simple request to estimate a bragging rights number that would pass muster rather than to choose an injector size or estimate theoretical maximum power.
That was the initial joke. I smiled at Jason's comment
quote:
I think he's having a go at you
to show levity rather than discourtesy and later clarified that complexity was not the issue. The formula produces result error linearly related to estimate error in the "ballpark" BSFC plus further error on duty cycle measurement assuming anyone could be bothered to do that to discover that, amazingly enough, a V8 produces in stock form about 60KW less at the wheels than the advertising claims at the flywheel and that for bragging purposes adding 60KW to whatever tuned value you discover for a V8 will typically suffice where there is not significant difference in RPM at peak power.
I did not say your response was inappropriate in the sense of being improper but rather, inapt. I am sure it helped someone or at least piqued their interest and so you are quite right not to give any little red stars about it. cheers

From too complex to inappropriate to inapt now. David, there is no need to pussy foot around, if you have a problem with me or it was something I said in the past, take it offline with me. I'm happy to talk it over with you.

I fail to see how any of the above would help a member plan the upgrade path of their V8! everybody always chants "search is your friend" but if i bought a new car then looked up possible upgrades and read the above....

Yeah, Right!........
I could probably count on the fingers of one hand the threads that've actually stayed on course ie:
THREAD. "Would my Soarer's bum look fat in this color"?
"No"
END of THREAD.
One of the many delights of SC to ME, is that for the most part we don't take ourselves too seriously, and often wander happily off course to the ammusement of the gathered throng.
If we ever get to the stage where it's all "Do it by the book", then it will become BORING & less attractive.
