yep...went to re-dyno the car, previous dyno was 434rwhp back in feb. i had a 2.5 section on my exhaust got it chopped off now..and boost'n. did 481rwhp at the same boost 19-20psi, with old 9's and with a boost leak back to 1.1 bar at 8300rpm. im running a BDC half BP, e6k, hks log, and a "Master Power" T-70 with a 1.15a/r turbine housing. still needs some fixin. when i do finish off the problems, im sure i will dyno past 500 with the same boost levels. heres the dyno sheet, any questions just ask

ddub

Nice! BDC's ports are definately some hawt ports. That's a very impressive dyno too, good job.

sorry ill rescan the dyno sheet tomorrow morning. with a full view.

ERic.

MidwestTurboII

wow, id love to see numbers like that some day.... especially since i also have a red 87 TII. How is lag with that t-70? id think it would be like nothing, and then all of a sudden WHAM, boost hits?

Wankel7

Man that is great! Ur my hero

Turbo II-FB

awsome ,but you have a little shakey problem there. Do you know what the problem is?

RETed

I can't believe you guys are taking the peak readings off the wavy side of the graph...
*sigh*

Long story...

If you can dig up my rant on BDC's "424" hp run, you'll understand.

The dyno graph obviously shows that the power is breaking up at the top end.
Nasty waves like that are not a reliable indicator of true power levels.
You get a spike going your way, and you end up claiming 50+hp more than what it's supposed to be.
In fact, when I try to smooth out the top end, the power is more like 450hp and not 480+.
For some reason BDC likes to do this...

Yeah, you can all call me a hater on this...
I just call them like I see them.
The dyno graph should be smoothed before making claims of peak power.

thats fine ted, call it like you see it, that dyno was the highest from MULTIPLE runs like 6 to be exact, all were very close in that HP area. that one being the highest, the engine is making that power no doubt, just having some trouble in higher boost as you can see im constantly making in the high 400 area, 2nd dyno untuned 16psi was 421. i had a hunch you'd post here, seeing how youre Anti MP turbos and anti anything BDC does. what is it going to be now ted ?

Bukwild

what type of fuel are you running?

TEZTnTUNE

ted does have a point your graph is all over the place. dont know if its your spark breaking up top or maybe you need to rescale your rpm points. whatever it is maybe u should post the whole graph including a/f plot?

ultradef

The dyno graph seems to indicate 112 octane I think. Impressive numbers btw, but you definitely need to smooth out that top end.

Bukwild

cool I was wondering if it was 112 added to a empty tank or 93 mix to 112?

Slammedblk7

iTrader: (7)

well i havent changed the plugs since before my feb dyno.. im pretty sure thats causing the nasty break-up. i had 1/4tank of 93 when i added 5 gallons of race gas, the a/fs were pulled out to high 11s low 12s.

iTrader: (14)

waht exactly will you be able to deduct from the entire graph?

BDC

Why am I not surprised by this?

For the "nth" time, the power my old setup made was legitimate. I backed it up over and over and over again and, for some reason unbeknownced to me, you still won't accept it. I don't understand why, Ted. It happened. It was real...

Same as yesterday -- although Eric's car was getting jittery up top, it doesn't mean the vehicle didn't make the power it showed on the dyno graph. 15 seconds riding in the passenger seat of that car, on the way home, with that setup, would probably convince you. We made over 20 pulls yesterday; heck, maybe even 30 for all I know. I logged many of them and checked the power vs. boost on all of them.. The power output is legitimate even if there's some struggling up on the high end. The only thing I can think of that's causing it is problematic, old spark plugs.

Ted, I get the feeling that you don't seem to have much appreciation for any of the stuff I do; atleast, this is the jist of the attitude I've gotten from you. I'm not meaning to dodge your point about the jitters on the graph, and they are bothering me 10x more than they're bothering you, but I still get the feeling that you seem to be hell-bent on trying to knock me down on anything I do. It's been a staple of your posture towards me for I don't know how long.

So, if this is the case, then please put a stop to it. There's nothing you can say or do that's going to abate my efforts nor stop me from doing any of the work or experimentation I do. I call things as they are; Eric's car has crossed 400hp and is approaching 500. It will make it like many other cars I work on. My question for you, sir:

Where's yours? Where's your figures? Where's your dynos? Let's check out some of your stuff, friend.

112 leaded race gas.

Go talk to anyone who is competent on dechipering dyno graphs.
9 times out of 10 they will tell you the same thing.
That's all I'm going to say about that.


-Ted

BDC

The only thing that can be deduced from this graph, in my opinion, is that there's some sort of break-up or slippage or something. It's a jittery curve; it was from the start. The car felt different on the dyno than it did on the highway back from the dyno. For all I know, the tires could be slipping. The plugs could be bad. Who knows?

It's still making the power as claimed and doing it over and over and over again.

BDC

Since you are implying that you fall into the category of being "competent on deciphering dyno graphs", then please give us some specifics instead of shooting spit wads at us.

Sure, I left the other thread alone, cause it would've all ended up the same.

Oh don't worry.
It's coming.
I put money it'll do better than the "424".

Oh, BTW, I have never seen the "424" backed up.
Unless you're posting stuff on TeamFC3S.Org which I am still banned for some unknown reason, I haven't seen any evidence of a backed up run.
I believe the engine has been blown up and rebuilt several times since the "424" run.
I'd be happy to take a look at any proof you have laying around.

Oh, as for the repeatability of the dyno runs.
If this is the case, something is drastically wrong.
If the dyno graphs are consistently wavy like that, I would put the blame squarely on the tuner...

Now that just opened another whole can of worms...

Hi Ted,

I posted a graph that was 423hp just after the 424hp run in a thread from September that you were arguing about, then. I am sure you remember it. I also have sheets doing high 410's over and over again during that same day, friend. I did it; I backed it up both on successive dyno runs and on an 8th mi track where I ran nearly 98mph at the top of 3rd gear on drag radials. That was in March and April of 2000.

You can place the blame on me all you'd like but all you are effectively doing here is acting like a jerk by ignoring any of the claims or reasons I may be giving that may deserve the benefit of the doubt as to the source/cause of the jittery output graph. The fact is is I was there every single time and you weren't. I worked on the car, I ported and built the engine, I did both the street and dyno tuning, so by way of that, that makes me privy to all of the information and truth of the situation that you are trying to effourtlessly argue against. You weren't there; all you have is conjecture and your own narcissistic, cynical attitude, seemingly looking for things to try and embellish negatively on in an attempt to downplay the significance of the work that I do. In short, you're coming off as an unreasonable "nitpicker", hell-bent on bringing me down. I'm not falling for it and anyone worth their salt, that actually has experience, that is mature and rational, won't fall for it, either.

Again, the figures are real. Ride in the car someday and you'll see that they are indeed real. The car is a fast SOB; it feels capable of a high 10 second pass right now I think. It still has some quirks to be worked out, but it's certainly on its way to 500rwhp.

For the second time tonight, where's yours? Where's those figures? Show me some of the dynos of the engines and cars you've either built or have been a part of working on, Ted. Let's see them. Let's see your posts with questions and problems you're posing due to the stuff you've tuned and worked on. Let's see those same jittery output graphs; let's see some of those not-so-even air/fuel ratios. Let's hear about the hours spent in a carbon-monoxide shop working on a car just because of the self-respect it brings. Let's get the spotlight back on you for a minute to substantiate some of that alleged "experiential knowledge" of yours and show the world just how good you are with the work you have _actually produced_.

In one way, I am flattered that I have your attention. It shows that I might be doing a good job in my work.

I know your kind; I see right through your BS.

BDC

Thank you, dDub. Those are from an old porting style, too.

I don't know wh at was causing the break-up up high. I'm still not even certain that it's "break-up" per se. It could be the drum for all I know . A/F ratios were straight, nothing too rich or too lean, and the leading and trail-split advance was set well, smooth, and sequential. The spark plugs were old and have gone through alot of junk, so there may be something there with it.

Could also be something else unforeseen on the car as of yet.

I can't see how Ted has a point. The dyno shows multiple runs. Yes, it shows breakup. It maybe plugs or ignition problems, but the power was still made and when the break up is solved the plot will smoothen out with about the same if not MORE power, not less.
