Finally went to the dyno

[poolee]

After a year of draggin my feet, I trailered the car up to Orlando to get a dynotune on my diablosport. The chip that was in there was from the original motor with 8 lbs of boost.

I had changed to a 2003 DSS motor and moved up to the 12 lb pulley on the procharger. I also put on shorty headers, handmade a new intake tube for the procharger, installed a complete fuel system with 8AN supply and 6AN return, and a Kenne Bell Boost-a-Spark. It was a pretty decent jump in hp and torque.

Does anybody care to guess at what these MustangDyno numbers would equate to on a DynoJet?

The year on the orange one is wrong, it's from 2004. As you can see, they couldn't even get a full pull on the old tune.

mustang dyno's are usually about 15%-20% lower than a dynojet.....so i think it would be around the 390ish range. but you have a built short block......turn up the boost

Yeah, I'm thinking about getting some cams and maybe going up to 15-18 lbs. Would the stock head gaskets hold that much boost?

i wouldn't trust them, but that's just me, & i don't know how well the stocker actually hold up under that much pressure. i would just get some thick copper ones, they aren't all that much. but cams & turning up the boost, that thing will get wild i'm sure
