The "Gredge" stretching its legs on the dyno ...

[Jack Valiant]

Hi Guys

Well it was the day to do a final run on the AMD dyno for the "Gredge" after a change of fuel regulator, 14CUX chip AFM and one or two other mods I had been meaning to do.

Turn up the volume!

Like it Chris.
Chris Im assuming this car started out as a 350?
If that's the case have you done any mods to the diff or gearing in some way because I reckon that's going to be one of my future jobs, I find acceleration is quick but don't really need 1 st gear,id appreciate your comments,cheers for now john.

Yep was a late 89 350 S2. I have put in it a refurb 450SE gearbox but standard LSD diff. I was told that the box has slightly higher 4th and 5th ratio. I agree that 1st gear is hardly needed with all the power on tap but if I floor it in 3rd and 4th its off like a scalded cat! There seems to be a 6-8 mph difference in the speedo and GPS which would seem to confirm it. At 3k rpm in 5th gear the car is doing 76 mph and at 4000 rpm there is 285 ft lbs. happy to discuss some time fella

Lovely.. a powerful, good looking beast you have there!

[Jack Valiant]

Do not think there are any fuelling issues as the AFR across the run was all good and within the norm for the Serp Griff motor. I have fitted a 3 BAR FPR rather than the normal 2.5 as it was marginally lean as we approached the limiter

Here is the data for info:

And if I read that graph right, an almost flat torque curve from 1000 (ish) to 4000 rpm ?

Wow ! That MUST be fun to drive !
