Dyno Day Pictures

WOW !!!

Thats all I have to say. There was at one time 60-70 people, Hamburgers, HotDogs, and about 20 cars on the Dyno. Great turn out !!!

Next time its gonna be even better, I promise.

I post the pictures, you post results.

Believe it or not, this one blew a weld and shot flames out the manifold.





and the GT500E

That was a great event. Well run and very profesional. Despite my muffler blowing off and wounding the air fuel sensor- they let me stick around and even fed us.
Thanks.

Scott,

What did you end up making for power? What was the comparison between supertraps on and off? Just wondering.

Scott,

Very eye-opening numbers. What I felt seat of the pants last season was confirmed by the dyno. 242hp to the wheels at 4500 rpm and 335 lb/ft tg.
The last time I dynoed it the end of the '04 season the readings were 275 hp at 5800 rpm. and 290 tq. I'm not sure what's up with the torque #s but it was enough torque to rip up one of my tires on the dyno. We didn't get any supertrapp #s because one of the mufflers blew off- but I could feel a substantial decrease in power during the pull.
There's work to be done on th hp #s. I think it's a tuning thing not a sick motor.

If I had posted those #'s on my dyno runs last week, I would have checked to make sure 2 of my 6 spark plugs were still working

HP = cubic $

There is no amount of $$$ that can make mine sound as good.
I told Ryan I will move to PA this year to let Mario and yourself duke it out in SPA. I just hope there are some playmates in PA or I'll have to put the rear glass back in and come down to SPA.

Rumor has it there are 14 SPA cars registered for NHIS1. My mindset is to make laps and have fun- whatever happens, happens. I will not be going to Shenandoah, so I have no championship plans at this point. Of course that all could change with a couple 1sts and 2nds

You may have seen lower Hp readings due to lower coolant temperatures. I know it sounds wierd, but it happened with mine. I dynoed in January, when it was 15 degrees out. I have a 160 degree thermostat, and during the dyno runs the highest coolant temperature that we saw was 120F! Since the coolant temperature was so low, the fuel mapping in my car was telling it to maintain an AFR of 10.6:1. Once the coolant gets into a higher temperature range (170-180), the AFR is targeted around 12:0:1. This leaning it out more and making more power. I have dynod since then with higher temperatures, changed nothing and saw about a 35 hp increase. I could be completely off base, but just something I noticed myself. The torque sounds pretty healthy though!!!

That's interesting, because I did the pulls stone cold. The final coolant reading was 150 deg. and that was when I was shooting mufflers at the bystanders- so we really didn't get any data there. I had just re-installed o2 sensors the day before. All last year the computer was just running in a loop.

Sounds like you guys had a blast, sorry I couldn't make it -- I figured I better finish the car instead...! Getting close, I'm down to small stuff and bodywork now.

Scott, we've got to get a big chain or something hooked to that Supertrap, eh?

14 cars in SPA! I better get one of those "pray for rain " stickers on my car!

To give you a better idea on HP numbers and if there is any question on the accuracy of the dyno,... read this.


This really sucks for all the DYNOJET owners out there who think there HP numbers are correct.

The DYNOJET fudge factor straight from the horses mouth!!!

While many think that the industry standard for chassis dynamometer HP is DYNOJET, there may be something you don’t know or have a hard time believing. That the numbers reported on a DYNOJET are fudged higher simply to make them more acceptable.

In a recent article printed in HOTROD Magezine, Mark Dobeck the creator of DYNOJET spilled the beans on the “fudge-factorâ€

14 in SPA I might have to put the glass back in just for the fun factor of running with others. Any idea the # of contestants for PA? It's no fun to run in a class all by myself I know I'm out for the first Mosport and Shenandoah so a class championship is out for my also.
