Well I took the car to the dyno today and I am fairly pleased with the results….
The only change the tuner made was he put in more timing, I had it at 36 and he took it up to 40 (running 93 mixed with 100 octane which is the norm for me, we have 100 octane at the pumps in my town). The race demon was fine right out of the box as far as air fuel ratio so nothing needed there.
It made 368 HP and 397 ft lbs of tq. He said the results are a little conservative as he could tell from the very flat line on the graph that my race converter is loose. He also said his dyno is calibrated for a 3800lb car and I only weigh 3000 to 3200 (not sure if that means anything, he didn't elaborate on that) He made some calculations and he said taking into consideration the C4 trans, and that my converter seems to be pretty loose he estimated that I have 475HP at the flywheel. I always thought I had between 475 and 500 FWHP so I guess I am happy.
With that done I have an appointment with the fabricator next week to look at getting my custom cage re-installed, installing my new Kirkey low back vintage road race seats (I have them and they are sweet and pretty darn comfy for being an 11 lb piece of aluminum) and installing my 5 point harnesses. I hope he can get me in in the next couple of weeks so I can make a pass in the car.
Most of you guys know my previous best run was an 11.28 @ 119MPH before the cam, stall and carb change was done when we freshened the motor. So I am hoping that the stars will align and I'll get that 10.99 pass out of the car NA yet this season, it feels so much stronger than before...... wish me luck.
