yellowss7 Posted August 27, 2007 Share Posted August 27, 2007 Alright Al, I'll bite, where were you on the Revs when you shut it down? Sounded like there was more there. Tom Link to comment Share on other sites More sharing options...
Al N. Posted August 27, 2007 Author Share Posted August 27, 2007 Tom-I was using a 7500 redline...which is probably a few hundred conservative...but it was the first time on the dyno and all... Link to comment Share on other sites More sharing options...
SR27.Seth Posted August 29, 2007 Share Posted August 29, 2007 Tom-I was using a 7500 redline... Funny- I thought the same thing that tom did- If the car was in 4th (which it should be) it sounded like she only pulled to 6000 or 6500 max, When I have the time I'll post our cars pulling to 7500- much more violent sounding. Careful with those portable rollers- they can be quite inaccurate with their numbers Link to comment Share on other sites More sharing options...
Al N. Posted August 29, 2007 Author Share Posted August 29, 2007 Thanks Seth...it's a permanent dyno install. Regarding what gear...if the Caterham 6 speed box is 1 to 1 direct in 6th as Cherik states...isn't that the right gear? Link to comment Share on other sites More sharing options...
yellowss7 Posted August 29, 2007 Share Posted August 29, 2007 Al, 6th is 1:1 on the Caterham 6 speed, so yes it's the right gear. Just sounded so smooth. Tom Link to comment Share on other sites More sharing options...
SR27.Seth Posted August 31, 2007 Share Posted August 31, 2007 Wow!- I had no Idea the Caterham box was soooo close ratio!- 95% of RWD gear boxes are 4th 1:1, and I have only ever seen one or 2 5th gear 1:1, Even in Ford Motorsports infamous 7 speed the 4th was .955 and 5,6,7 were all overdrive. But a 6th 1:1- Boggles the mind. Does anyone know the other ratios? ...it's a permanent dyno install. Sorry to offend Al, at first viewing I thought the car was in the back of a big trailer- upon a second look I now see that it is in a garage Link to comment Share on other sites More sharing options...
