Which A/R...?

As some of you know i'll be going single in the not to distant future and have decided on a T67 with 4"DP (as i'll be going for a BL Exhaust).

 

Most of my sprinted driving will be dual carriage way's and motorways, so which A/R (Exhaust side) should i go for,

 

0.58, 0.68, or 0.81?

 

I assume the higher the number the higher top end power?

Also i will be going for 264 cams.

Agreed. 0.68 is your best all around A/R.

 

The 0.58 does not have much top end.

 

The 0.81 will increase your lag and top end, but its a noticeable amount of lag that most will not care for.

 

Going from stock twins to a T67 4" setup is already a huge jump, you will be flying by everything anyhow. :)

 

Cheers,

 

Dusty
