My car misfires at 12psi with the 1.8 coils. No dynoing for me. I'll be there for moral support however, and cause I miss you guys.

Lars has PNP 94-95 COPs...

what are you gapped at?

I also have two of the VVT coils/cops if you need to testicle

My cops are hardwired to my harness. Tim can not have them.

On the plus side I hit 235kpa today where my boost cut was at. The car is starting to be fun.

Sounds like this dyno party is gonna be awesome. I can't wait!

Noob will be coming too. But my Miata will still have to wait for me for another 3 weeks, so I'll be in my Station Wagon....

I may likely have my car in top working order. I would consider running on the dyno if maybe someone who was supposed to run pays for my spot. in return, I will limit ridicule to almost none.

Thanks Y8s, I almost sprayed scotch all over my laptop screen when I saw the "Rick is great" in your signature!
Perhaps you could take Min's spot on Saturday after he does his 5 shot penalty for not getting his car done on time.

who's meeting in Arlington tomorrow AM?

I might meet you guys from bed....

... Since somehow the path from Sunawee, Georgia to Reston, Virginia is through St Paul, Minnesota.

Now that I know we're meeting in Arlington tomorrow, I guess I will show up. Where exactly, and what time?

you know where, and 8am.

Y8's house is the meeting spot. I think he said he wanted to see which one of us had the loudest sound system in our cars at 8am SHARP!

I plan to be there at 10 and leave at 12. Need to be back home area by 2:30. Lame.

I successfully made it up to NoVA. I will beet meeting people in Arlington at 8am and we should be at the Dyno around 9ish.

Also new Camaro RS are slow, from a roll 80-135 it got rocked. The chick driving looked sad, her bf in the passenger seat looked even sadder.

Chick driving a v6 pony car is slow. In other news, water is wet.

Lol! P.S., Min. What are you doing on here? Shouldn't you be in the garage wrenching?

Bed time. See you punks a few hours after the sun rises!

Is the RS a v6? I honestly do not know. She was the one who reved at me. I did not see that it was an RS until I had slowed down and then she flew past and started weaving in and out of traffic. I went back to my 80mph and just kept cruising.

If any of you douches attending are reading this, PM me a cell number so I can see if people are still around when I can come up. I live about 1/2 hour away and can probably be there around 2:15. I'll text to check status at the dyno.

Thanks,
Frank

Cant make it, tranny still blown haha.

So it was a good day at the dyno. I ended up making the most power at about 240hp, unfortunately my car was shooting flames out that back which was causing us not to go to redline. On the street I am not having the problem. So I need to figure that out. I am definitely upset that I could not hit 300hp. Hopefully soon I can afford to actually go dyno tuned and figure hit the power numbers I want.

102hp, yeahhh!! So exhaust, cops, exhintake, seafoam and a better tune netted me 8hp. And I guess I didn't quite drill the cam gear in the right place for the exhintake mod cause max power is now at 6000rpm vs 6400... anyways, here's a vid of Lars making fire.

I had a great time as always meeting all you guys in person. By next dyno I swear I'll have a stronger bottom end and a Godspeed gt3076.

epic winning!!!!!!!!!!!!

Like Min's kick ass Charlie Sheen t shirt?

I took a nap and played some Resistance 3 and saw a movie.

I think I felt maybe like 1/4 hp.

I made it out for Chipotle afterwards. Rolled up and everyone was gone. It was a good day to drive topless though. A bit cool so my nips were perky.

It was fun and definitely a great day for a ride. Still unhappy I don't have my Miata yet...
But it was great meeting all of you and to see that turbo Miatas are alive and well. It's also incredible to see that no two engine setups are even remotely close to identical! I wish I'd seen more Miata runs, but I can't wait for spring when I can Dyno my own!

Anyway- here's some random pictures from my phone:

I'm pretty sure he was loading up your car wrong. he did something to the gearing ratio or something, cant remember what like rpm/mph and it was way off compared to every else's even though you still have 1:1 and 4.1 final in 5th gear.

He was definitely changing something trying to get rpms right. They should have been close because he had them right in the spring with his original settings. Ed also kept trying to run in 4th and I had to keep telling him to run in 5th.

Did you happen to get a print off of my runs? I totally forgot to ask him for them. Maybe I will call up tomorrow and ask if he could fax them to me or something.

Why would 4th vs 5th affect hp? I thought that the only effect would just be to make the pull longer?

Did anyone's wideband agree with the dyno wideband? Mine read about a point leaner...

My wideband was reading about half a point leaner than the dynos based on my logs. Lars probably just fried the o2 sensor with his fireballs. :)

I'm kind of wondering if something was going on, as I was a good bit down on power from the spring (98 peak vs 105) without significant changes to the car. The plot was much smoother this time after messing with the AE settings and the powerband looked the same but was shifted down everywhere.

Soviet, what were you putting down in the spring? I was peaking at 105 in the spring with an exhaust, crappy tune, and a ghetto shopvac hose intake. Did anyone else see some odd variations between previous runs and yesterday? I figured with as cool as it was yesterday if anything things would be skewing higher.

But when Lars' car was running under low load and not boosting the wideband read 14.7 constant as it should in closed loop (assuming Lars' car goes CL). So under non-rich conditions it seemed OK.

In spring I was at 94hp but with stock exhaust, stock intake cam and stock ignition.

well, I was at 83 whp on a pretty stock 1.6 with 67K miles on the engine. Ed asked me about my diff and I mistakenly told him it's a 4.3, but it is actually a 4.1 Not to mention the annoying exhaust leak. Not sure if this explains why so low, I am very tempted to run a leak down test on the car. The compression I did a couple of weeks ago was great (175 across all 4) so not sure what else could explain the low output.

Soooo why does this guy have to enter anything for gear ratio? This is what makes this type of dyno 'better' than a dynojet? :dunno:

Do you get your $50 back if the dyno operator fails?

Nice to see some of you guys again. I got to see part of an old turbo porsche's dyno run.

because instead of a pickup on the ignition, the dyno reads the engine speed by the rollers themselves.

That's what I assumed when I saw the Porsche run, but I assumed that was because they couldn't reach the spark plugs under the intercooler. But really? No RPM pickup?

What did the Porsche put down, 170? I don't know much about them in general but when I saw "Porsche" and "turbo" I was expecting more.

I thought I saw the monitor read 235. In fact I'm sure I saw it read 235, and the AFR's were 10 all the way across. Stupid rich.

Oh, that would seem more reasonable. I think they didn't wind it all the way out on the first couple pulls, and then I left to go look at another car while they did a few more pulls. I do remember it being crazy rich, guess that provides some safety margin for an air cooled engine.

I wanted to see that turbo'd karmann ghia do a pull. That thing was SICK.

motor was blown on the kharmann

Blown as in "it was ceased up", or blown as in "boosted"?
Not sure if this was serious or humor, cause if /\ then LOL.

s sh sh sh

SHITS DONE BEEN BLOWN TH FUCK UP

There is a lot of jibber jabber in this thread and absolutely no dyno plots.

the fuck.

i took like 5 pics of the kharmann, thats about it.

everyone had brain busy.

Don't worry about it, that dyno is a heart-breaker. You just can't compare numbers from different types of dynos.

so that means the final gear ratio is important, as well as actually KNOWING what is the final gear ratio. is there a way to "re-calculate" what the dyno would have read with a 4.1 diff ratio setting (instead of 4.3 which is what Ed assumed).

assuming a linear relationship (this may be a faulty relationship), the mighty 83 whp would turn into 87 whp (which is probably closer to what I would expect of the engine).

Florin

nah he fixed yours because the redlines matched. the only thing it would chang ein this case would be the hp vs rpm. where the computer might have shown 85hp at 4k instead of 7k.

but i do think he did something odd when lars got strapped up, maybe he had the load turned up or something, but i do notice he doesn't run it like I'd expect on a dyno dynamics, where he would be WOT and turn the load on his controller to bring it to redline.

Maybe we find a CheaterJet to dyno on in the spring?

works for me.

The dyno measures wheel torque and wheel rpm. The HP can be calculated from those 2 via HP = TQ * RPM / 5252. It doesn't matter what the ratio is. The only thing it affects is the RPM plot, like Brian said. So instead of 80 hp @ 4300 rpm you're actually 80 hp @ 4100 rpm.

Yup that's correct.

Dynojet. :werd:

Let's just do a virtual dyno. whee.

BTW Lars can you look at your logs? what was your kpa/psi?

I think if you are not in the 1to1 gear the amount of torque you output will be off. In lower gears you make more torque. Since the dyno measures torque and then uses the formula compute hp. So if you are not getting a correct torque value your HP will be off.

I looked, I am not running enough. I was hitting around 200kpa.
