Dyno Test Results

Harry · 05-19-2003, 08:24 AM

Hey Everyone,

I had my mustang Dynoed last weekend. I was kinda disappointed in the results, but then it's an 18 year old car with 150K+ miles that can still smoke the tires.

I know heads are in order. Not really wanting to put on pulleys, I've had some cooling problems. But any other suggestions? And what do you think about the results?

Sorry for the crappy picture. If you can't read it, it's 198HP and 244 ft/lbs torque. They guy that dynoed it said that I would lose 20% in drivetrain, so I figure I am around 240 horses. Stock was 210, so I am up a little.

sweet.... I remembered the first time I dynoed my car.. I pulled a 240hp/300tq at the wheels, and that was on a stock long block.

time to get more mods

I don't think that's too bad for your set up. Seems like the engine has been rebuilt at some time. (306, forged pistons, Sealed Power, E cam, etc.). Hows the cranking compression? And how many miles on the rebuild?

A windage tray and crank scraper can add a couple of ponies without any negative effects. Some kind of cold air / ram air system also can help some without hurting anything. As you mentioned, better heads are needed. I like TFTW or AFR.

The March under drive pulleys didn't hurt my cooling any on my car and it was always borderline. Now with an Edelbrock water pump, 4 row radiator, and a Shelby front valance, and an auxillary 16" electric pusher fan on my '66, it stays around 200 F even on hot 100 F days, even with the pulleys. I was worried about cooling and charging before I installed them, but it turned out to not be a problem for me.

I think you're #'s are pretty decent for what you've got. Get a performer RPM ntake and that'll open up a good chunk of power, especially high up.

Rev, thanks for the suggestions. But what is a windage tray and a crank scrapper? Yes, the engine was rebuilt about 10,000 miles ago at a local performance shop. They said I would get around 260-270 HP out of it, I guess they overestimated a little! I'm not sure about the compression, I've never done a compression test.

So you like the TFTW or APR heads better than the GT40s? Was hoping to pick up a set of GT40 (either cast or aluminum) for it.

Thanks

Harry
