416 dyno results --------------------------------------------------------------------------------
Finally got the car on the dyno. We put around 600 miles on it before strapping it down on the rollers. I did this so we could tell the tuner about any issues that we were having with the driveabilty of the car.
Flaco did the base tuning and was with us at the dyno. Now for the results. The good news. NA the car put down 508 hp with the curve being nice and smooth. The engine pulled all the way to 7150 rpm with Ed's (FTI)cam and spring package, and L76 intake. 7200 rpm is where the limiter is set. Looks like we will be going with a Vic Jr or the new GM Hi rise intake and T-body Plate. This set up wants to rev. Now for the bad news.
We fought a no start condition for several hours when the wiring for the Timing Tuner went bad. This harness connects to the crank sensor and when it went bad the engine would crank but would't spark or fire the injectors. The computer didn't give us any DTC's so it kicked our *** till we figured it out. After by passing the Timing Tuner Flaco put a N2O tune in the PCM and we were ready for a pull. On the first nitrous pull things went from bad to worse. Half way through the pull the torque converter bolts backed out and all hell broke loose.
The damage at best is a new fly wheel , oil pan, converter rebuild, and tranny bell housing. I haven't pulled the tranny yet so I don't know if the pump or shaft is bad. All in all the day sucked!!! This project has been on going for 2 years and looks like it will continue for another 6 mos. Thanks to Flaco for his help and to Richard at Strictly Performance for the Dyno rental.
We will be back with further up dates. Oh the dyno pull was with the converter locked through a 4L60E, 4:11's and 275-35-18 drag radials. Non corrected with mid 90's out side temps. IATs were in the 100-104 range.

Wow bad news on the dyno session. Guess its better to have failed there then out and about or in the middle of nowhere.
Please do an update when all is said and done. Good luck getting her ready for dyno day II.

The bolts go into blind holes on the converter, they had loc tite on them. You can't use nuts on the bolts. My guess is the threads on the converter mounting pads were worn. Yes trying to cut some costs wound up costing more. I should have had the conveter reworked.

Yes they are here in the Houston area. I had them do some minor exhaust work and used their Dyno. They are more of a Mustang shop. The cam is 620's lift and 242 in and 250 ex on a 112. It likes to rev, just like ED said it would. Oh check out their new 11 stang video. Its on this site in the TX section.
I'm going to fix whats broke and then look into getting a new manifold and T- body.
