I'm not to sure at all on this one since i have never run my 6 down the 1/4 mile yet... but what would a stock 6 be running at the strip?

1985 US 635Csi 5 speed 4240 lbs

OE is
3430cc M30
Motronic
DME II
92x86, 8.0:1
185bhp/5400rpm
214lb.ft/4000rpm


I own a dyno so here is the output at the wheels.

HP loss in transmission and differential 25%
So 222 HP at shaft is the result.


I am using the J C. chip also, a 3.71 ratio, with 265 Getrag.

The sweet spot of the m30 is now at 2200rpm where it was at 2800rpm, before the MAF installation.

That is the point where the rumble of the exhaust resonates in frequency with the intake. On the unmodified it is only seen on the cold mornings when the fuel system adds a little more fuel and the cold air is giving it's all.

I really like it, but not a race car.

Here is a Dyno of a Mustang race car, not mine.

He told me this Mustang ran in the 11 second grouping.
