Made 202.5 HP and 279.4 FtLb. Dyno Dynamics Dyno in Colorado Springs, 6000Ft. The SS made 377.9 HP and 371.8 FtLb.

The guys also did a wideband on it and said it is really rich. Suggested smaller jets for the carb, is that the only way to lean it out? Or is there a way I can burn the extra fuel? Hotter plugs, i dont know.

 

 

That 202 seems a bit low for a 350, were you hoping for more than that? That puts you at a little less than 250 h.p. or so at the flywheel. Does your engine have a 4 barrel? What else if anything has been done to the engine; type of cam, intake manifold, etc.? When running rich, smaller jets would be the thing to do. And I see you're in Colorado, how high are you? Elevation does play a part in what jetting the carb wants to perform at it's best. What other tuning you can do to the carb depends on what kind you have.

 

It is a summit 4bbl with an aluminum intake. It was a package deal. (pretty sure you helped with that install ). Other than that it is still the crate 350.

We are about 6K ft, I already ordered the jets that are 3 sizes smaller. I looked at the book and it said to go 1 size down for every 2000ft above sea level.

I had no idea what to expect, I wish I would have gotten it up there with the cracked 2BBL, rusted y pipe single exhuast, and no headers. I was happy that the torque is up there though. My goal is to do a wheelie one day, so I guess thats the way to go, probably only 1000 more HP/FtLb's to go.

Oh yeah, I think the summit carb is made by holley, it was one of thier models that just didnt take off from what I read somewhere.

Oh, Oh yeah. The dyno dude said with the right jetting it should easily get 20-30 more HP.

 

Put on the new smaller jets and cranked it up in the garage, the gas smell goes away after 19 minutes instead of 20. I'll have to see if I can tell a differnce once I get it on the road.

 

How much does it cost to get dyno'd? I notice that you're in Colorado Springs (I'm living in Denver). I'd love to to see what my Camaro is putting out.

 

The place I went to is $60 for three runs +10 for a wideband normally. They were haveing a dyno day the day after I went but the guys were cool and gave me the same deal, 3 pulls for 40 +10 for the wideband.

here is a link to thier site

Looks like they work on mostly suburu, but they didnt mind a Camaro one bit.

 

edog, did they test your Camaro with the front or rear tires on the dyno? That could explain a lot!

 

Yuk Yuk Yuk......
everyone's a comedian....

If you must know all 4 were on the dyno. Maybe they divided by 2 then.
