If you want to show falsely large numbers then use it. If you want to show "true" comparable numbers than use SAE...
2-4% is a low guess too.
Maybe I should go around quoting nearly 200HP then. Even though my SAE rating is 187HP ~ I think I'll go change my sig now... :rolleyes:
Lemme guess... You quote STD numbers too and I stepped on your inflated toes...
So I ask again...
Show me the "true" numbers...
...actually from what it sounds like it will all be moot since they will dyno it with an audience. So we (better) get to see them anyway...
I still applaud the work that went into doing this, just not the attention to detail and "what looks like" lack of proper design planning. I'm not the only one saying this either...[/QB]
Me, my inflated toe? Please, I don't bench race nor do I race on the dyno. I go to the dyno to compare before and after mod number and the dyno is strictly use as a tuning tool for me. My racing is done on the track; I don't need to post my dyno number in my sig.
The point of my post was that you quickly jumped on the number is STD not SAE and pretty much said the number is invalid(as in your quote, falesly large number). The fact is that you don't really know the difference between the two; there are only 2%(4% being high) worth of difference if you actually have a SAE and STD number on the same day/same dyno. I have, my first STD dyno number was 284 rwhp while the SAE was 278 couple years ago; that kind of difference stay the same even on my last dyno(over 100 pulls in between). Not sure about where you got the 200 hp but you might want to re-check your dyno plot again. :rolleyes:
Second, there are a lot of variables between dynos. Just a simple 10 psi worth of difference in tire pressure can result in upward to 10 hp on the dyno. Then there is also the different tolerance on each individual dyno. Some are calibrated to spit up higher and others are lower. Shoot, I am sure you have also heard the mustang dyno and the dynojet comparsion. With me being a curious person, I took my car to a mustang dyno in the morning and made a trip to my normal dynojet afterward and found some big difference. Both numbers were SAE but to my surprise there were 8% worth of difference.
So let me ask you, what is the "true" number? The true number should be what kind of difference did it make before and after the install; instead of going to different dynos and trying to obtain the best number.
Anyway, sorry for venting and for such long post. I am done.
On a side note, here is a question that none of you haven't asked. Is the turbo running off one exhaust bank or is it running off both exhaust bank? It would explain why the boost doesn't kick in till 4400 rpm if only one bank is running it. Plus that motor might not last that long if it's running off one bank.
