f13

[tonydry]

anyone know what bhp the f13 could handle could it be made to handle 200bhp if so how much would it cost

[Aragorn]

well F13 stands for 130ftlb torque

so i'd guessa 200bhp engine would blow it apart

[TRD_NOVA]

hmmm, there goes that idea tony :P

P.S. Bugger :cry:

[Fester]

the f15 is a small block gearbox...

[tonydry]

could the f15 be uprated to handle 200bhp

[rgv_stu]

f10/13/15 could take a guts full
just fit a quaiffe gearkit

as for the f no. telling the amount of torque thats an old wives tale. cus the torque is gonna b different in every gear and the ratio's are different in each box. it makes little sense.

[Dicko]

its not related to bhp it the torque. if your putting out over 120lbft then id go with an f15 or use an uprated f13 box <not cheap

[tonydry]

thanks lads ive been i contact with a few companys and thay recomend a quafe strait cut box ?1200

[Aragorn]

didnt vaux do an F17 for corsa GSi's too??

if that can actually handle 170lbft then u may well get away with it

[rgv_stu]

i would forget this f no. = ftlb of torque business tbh

the f10 and f13 have the same internals just different shape bellhousing
etc

i am using the f13 in a 1.7td running 20lbs boost which is anihalating 130ft/lbs, i'm putting out about 155ft/lbs & the box is fine
