Dyno Day tomorrow (nov 4)
Friday, November 03, 2006 5:04 PM
Ok so I'm strapping the beast down tomorrow on a Dynojet. 2 pulls, $50.

Last year I rolled on a dyno of unknown make...in the dead heat of summer, and it made 182HP @ 5700, 180tq @ 3300. Tomorrow it's gonna be about 5 celcius, tops (you US folk can convert it yourself haha)

The difference in mods between then and now are the cams, maybe the pulley (can't remember which one I had at the time) and a pretty hefty rewrite of my VCM.

Here's what I'll be running:
-GM M45 Supercharger
-2.7" Embree pulley
-Gates Micro-V belt 72.2" (no slippage with this baby, it's damn near too small!)
-"Secret cams" swap
-RSM 62mm throttle body
-RK Sport 4-to-1 header
-Magnaflow Hi-Flow catalytic converter
-Magnaflow muffler
-Magnaflow 18" resonator
-2.25" custom bent stainless full exhaust
-Custom made cold air intake
-RK Sport lower engine mount with Mark Pain bushings
-RK Sport upper engine mount insert
-Polyurethane transaxle mounts
-HPTuned by Sweetness with some help from Shifted

A big cookie to the closest guesser!! And keep your fingers crossed she doesn't go kaboom on me...





14.330 @ 96.37mph

Hypsy is da wiener.

Certainly didn't pan out as well as I wanted it to. Real close to that magic 200 number, but not quite there.



Apparently I have fuel issues, based on what their wideband told me. The sniffer was stuffed up in the muffler so you can't say it's real accurate...but according to it as you can see, at around 4400rpm my A/F went from around 11:1 to stoich, then by 4800 it was at LEAST 18:1 (chart doesn't go higher than 18), and then back down to 12ish:1 by 5800. After the first run we hooked up the ol' HPT and told it to dump a bunch more fuel...So on the 2nd run (I don't have the line plotted but going by memory here) the AFR shot up even sooner, well before 4000. The dyno operator shut it down early on the 2nd run when seeing such horridly lean conditions apparent on the screen, yet I was watching the EGT on my gauge and it looked just fine. The odd thing is...for the first run which I have the printout, the HP line as you can see climbs steadily, no noticeable drop in power, nor is any felt when driving. I've been beating on this thing hard for almost three years now, and it's still stout as hell.

Methinks the machine wasn't working so well, it doesn't seem possible to me that the injectors would just take a complete and total shit like that, even after adding fuel for the 2nd run. I'll be visiting a dyno near my work that has a wideband that threads into where my EGT probe is, to get a better idea of what's really going on, and perhaps get myself a nicer set of power numbers!

And yeah yeah yeah I know, I know you don't have to tell me...buy a damn wideband!!! We'll see what the second dyno session shows and we'll go from there.

good deal man, but yes... wideband . good luck on the next run as 200hp is very close

Nice numbers Bill. I've been debating whether or not to install an AEM UEGO I got or to sell it. Looking at your graph its going in. How did the tuning Chris did for you work out?



Re: Dyno Day tomorrow (nov 4)

i was thinking of typing something like " dyno seemed messed up,, or something wasnt right."

Congrats Bill,see if u can get someone around ya that knows how to tune the HPT and 200 should be no prob.

Bill, your car has got to be pulling down better numbers than that. That dyno must be wacked or something. I'll have to let you know how my dyno turns out. Might want to come down to Milton and check it out.

Dude....take of your intake and run open throttle body.

There's your 200 whp!

What's surprising is his "tune" isn't as much as you'd all like to think, it's not far off of GM's tune minus some tweaking so something is up. To be honest, I took a look at the tune Ron did for 220 whp for that other gentleman and they were already quite alike... so what's going on is a little strange.

You could easily blame the tuning, but it doesn't make sense for the fuel to go from 11:0 - 18:0 without doing something completely stupid in HPTuners... which of course I know I didn't do.

As Bill said, to go that ridiculously lean the car would have thrown a random misfire CEL up top from the lack of fuel and the power would have dropped back sharply... which it didn't. Torque would have also been far far far below horsepower, as shown on previous lean dyno's on a J-body.

I'd prefer to have a wideband on his car but no go thus far, hence the lack of extreme fuel tuning. I was hoping his dyno today would allow me to do a bit but as soon as I saw the AFR's shoot up I waved the operator to shut down the run.

Currently we're all a bit confused by this... tack it up to inexperience at this point, but this is where you learn the ins and outs of these things - by trying. Having a tune that's so close to the one Ron did that runs so godawfully lean past 4500 doesn't make much sense....

Even when I ran Sweetness up to 18:1 back in September by accident (Car decided to hit 18 psi @ 3200 after I fixed a boost leak) there were notable results in power, the way the car reacted and the CEL blinking a random misfire. His car shows none of this, in fact he only gets 2 degrees of KR across the range at sporatic points...

His EGT's are only hitting like 1450 from what I remember... tops.

Something is up here. I'll have to get to the bottom of it.

Bill - we'll get better #'s next time. I was hoping for better but this is where you "try and try" again. Zero road tuning with a wideband = mediocre dyno... Derrick's car with a few hours of tuning and a flat AFR runs exponentially better. It's just a matter of seat time and datalogging.

Slowly but surely may some day win this race...

the dyno's wideband was at the end of the exhaust correct?!?!

DOES YOUR CAR HAVE A CAT?

if so that's why your o2 readings are messed around.

Widebands from the pipe tend to only be accurate if you DON'T HAVE A CAT.


So if you have a CAT looks like it's doing a damn good job in cleaning @!#$ out.





NEXT TIME TRY DYNOING WITHOUT A CAT, and you should see a LOT MORE ACCURATE a/f numbers.

oh btw, what size injectors you running?


-Trailblazer SS - not so custom 6.0L - custom intake - custom tune
- (1) 2.4L on an engine stand (1) blown trans (2) good quad trans (1) eco trans = party
