Hi Steve,
if you want to come over to Bahrain well i'm sure you'll get people form all over.. Oman, Qatar, UAE, Saudi, Bahrain and Kuwait!
2 places come to mind if you want a dyno,
1. Bahrain dyno, tel:
00973 36667616, name of owner:
Tawfeeq
the guy is a chevylover but i'm sure he can accomodate us mopar guys

. he has a 2wd dynojet
2. MME (motor sports middleeast): they have a Chassis dyno (it attaches to the wheel hubs).
tel: 00973 17737828, name: Aron (iirc)
Accomodation should not be a problem, if you dont want to spend on hotel rooms, clean furnished appartments are about 95USD per day. they are usually 2 bed rooms per appartment.
let me know if you need more details

.
regards,
Ahmed
