Until your friend ups the boost on his turbo Volvo.
Couldnt of said it better myself
Our Bonnies are great cars, but with a little bit of minor mods, WATCH OUT for those Turbo Sweed'*. We have owned 3-4 Turbocharged Volvo'* over the past 10 years, and are now on our second Saab 9-3 Turbo Convertible ('00). The only one we really modded was my brothers Volvo (1993 940 SE Turbo) a couple years ago, and I must honestly say that'* gotta be right up there on the list of quickest cars I've ever driven / been in. We did a CAI, Exhaust, High-Performance Blow-Off Valve, Saab Turbo APC Unit (Turbo Controller), beefed up the intercooler ducting, and turned up the turbo quite a bit (almost to max). The car didnt last long, and we actually sold it just before the motor went, but while he had it, that thing SCREAMED!!
1 - MY Bonneville
2 - 1996 Ford Thunderbird V8 (last year of the older style)
3 - 1994 Ford Taurus SHO (Automatic) - 5-Speed might've got em
4 - 1998 Jeep Cherokee 4.0L
5 - 1999 Dodge Caravan 3.8L (Short Wheelbase) - Dont laugh, that minivan was descent
6 - Tons of his friends Acuras and Hondas
I'm sure there'* more, just cant think of them right now (It was like 2 1/2 years ago, when I first bought my bonny).
Anyways, as long as he doesnt visit Http://www.ipdusa.com
