Spatt Posted October 2, 2017 Posted October 2, 2017 hi folks, Can someone convert 190 bhp at the wheels to crank power? this was at 5000 rpm from what i can tell.. dont know if you need more info? I worked it at 227 bhp at the crank using a convert on google not sure how accurate that is though. Thanks Matt Quote

Spatt Posted October 2, 2017 Author Posted October 2, 2017 its my car...... i'm sad to say..... RWD manual.. its a long story but i think the number is a bit low? Quote
coldel Posted October 2, 2017 Posted October 2, 2017 You are probably about right on your estimate, I think Abbey used to knock off 35 or so for wheel bhp. Quote
Spatt Posted October 2, 2017 Author Posted October 2, 2017 seems low following a rebuild would have expected closer to the factory 280 bhp least of their worries at the moment though just wanted to confirm my thoughts Quote
davey_83 Posted October 2, 2017 Posted October 2, 2017 Could have a sticking brake caliper causing the low whp figure. With the car on a very slight incline, foot and hand brake off will the car roll freely? Abbey uses a hub dyno? so a set figure would be 'added' to estimate the flywheel power not taken away. bhp is always worked out from whp, not the other way round from my understanding. Quote
Paddy78 Posted October 2, 2017 Posted October 2, 2017 I thought there was about a 17% loss in the drive train. So 220ish... which doesn't seem too far out. Doesn't sound particularly good though (Although the might has a particularly pessimistic dyno). Hope you get it sorted! Quote
Spatt Posted October 2, 2017 Author Posted October 2, 2017 I expect the engine will require rebuilding... again.... but just wanted to get my head around the figures they gave me last week thanks for the info guys Matt Quote
HEADPHONES Posted October 2, 2017 Posted October 2, 2017 Here's hoping there's nothing serious amiss for you mate! Quote
Jake.Lowther Posted October 3, 2017 Posted October 3, 2017 Stock the lower end zed is 270 something at the crank isn't it? Quote
G1en Posted October 3, 2017 Posted October 3, 2017 People are missing the fact that this was at 5k revs. My 350 made an extra 50bhp at 6.5k revs compared to 5k so without seeing a graph its hard to comment. 1 Quote

Makes sense, good point didn't read through it enough. Edited October 3, 2017 by Jake.Lowther Quote
Erni902 Posted October 3, 2017 Posted October 3, 2017 (edited) I agree with the above, mine made around 230 at the fly at 5krpm and peaked at 6.5krpm with about 270 so you are probably bob on with your figures Edited October 3, 2017 by Erni902 Quote
Spatt Posted October 4, 2017 Author Posted October 4, 2017 ok that sounds good to me didn't realise the power difference over 1500 rpm Quote
