Gramma's Car: the new project!

[njsteve]

Today was winter prep day. I added Stabil to all the tanks and filled them up. Took the SD455, the WS6, and Gramma's car out for runs on the same route.

I can definitely say that the Gramma motor is stronger than a stock SD455.

I tried the same off-idle take off up a long highway onramp near the house. The SD455 got traction, launched, and chirped second going up the hill, hitting around 75 once it hit third on the highway.

The Grammamobile spun the 275/40x17s well into second, then launched up the hill into third and was doing 95 at the same point that the SD455 was doing 75.

Can't wait to get a real exhaust on this car! [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

The SD has 3.08s and the Grammobile has 3.42s. The 3.08 rear gear would be a much better gear for the Gramma car. Those 3.42s are just a bit too steep for a low rpm engine. The power band is 2,000 to 5,000 on this engine. You really notice the pull when it hits the sweet spot. [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

Maybe Kwhizz can install an overdrive tranny for me. This car really needs an an extra gear.
