hi guys,
will a single inch and a half su be ok on a worked 1100? i only want about 45bhp. more after driveability than performance. :D

should be okay, but you can do better

i mean my 1132 with a single hs4 was great, but i definitely would have gotten more horsepower with a hs6 or twin hs2's

HS4 is fine, if not the best option.

I ran a 1.5" SU on my worked 1100. I think I hit 44.9bhp on the dyno.

45HP on the MRC dyno with my 1132 (more now since fixing it) and its running a 1.75" SU

Depends how its built and how much it will rev... you shouldn't but 'might' run lean up high... try a 1.5" and see if it performs.

Hey Steve,

Got any more specs on that motor?
What compression ratio?
What head?
3.44 diff?
What exhaust and intake?

Pretty impressive HP from a 998 mate... even on those rigged S.A dyno's (kidding mate)

Peter.
