Went through a pile of receipts which were in a bag in the MH when we purchased her. Found the receipt for the turbo. The van is 1990, the receipt is dated 1999. It details the make and model of the turbo, and also before and after BHP. It shows them as 62bhp before and 112 bhp after. I find this remarkable for 2 reasons. It was listed as having 79 bhp I thought, to be at 62 after 9 years o light use seems odd. And also - They more than doubled the horse power?!!? No wonder it goes so well! lol And there is me trying to get an extra couple of miles to the gallon with fancy tweaks! lol
