BB6 Report post Posted March 10, 2010 Put the car on the dyno when it was in for its annual all fluids change and got 414 whp, 408 wtq (lb ft) SAE corrected results. What sort of correction factor should you use to estimate power at the crank? Quote Share this post Link to post Share on other sites More sharing options...
Chipster Report post Posted March 10, 2010 Very nice man! Been a while since I saw you post on here haha. Glad the car is doing well. Quote Share this post Link to post Share on other sites More sharing options...
BB6 Report post Posted March 11, 2010 Very nice man! Been a while since I saw you post on here haha. Glad the car is doing well. Been itching to get it back on the road - just waiting for one decent rain to wash the salt off the roads first. How's the progress on your car?

Placid Report post Posted March 11, 2010 What sort of correction factor should you use to estimate power at the crank? 20-25% loss usually. Quote Share this post Link to post Share on other sites More sharing options...
BB6 Report post Posted March 11, 2010 20-25% loss usually. Thanks Placid. If I use a 20% drivetrain loss, that would mean a crank hp of: 414/(1-20%) = 517hp. That's a bit lower than the quoted 530hp, but the difference could be because of the ram air effect in the SV - though I seriously doubt they came up with the quoted figure in an accurate way using ram air effect, they probably just took a swag and came up with a nice round 530hp at the crank figure. All in all, I'm a happy camper. Now if anyone has a Series 1 LP400S for sale with Bravo wheels, please let me know :-) Quote Share this post Link to post Share on other sites More sharing options...

Difference between quoted & dyno hp#'s could also be attributed to either/or production variance and/or "age" of car i.e. decline in engine compression. Not a concern IMHO.

Chipster Report post Posted March 12, 2010 Been itching to get it back on the road - just waiting for one decent rain to wash the salt off the roads first. How's the progress on your car? It's getting there. Waiting for one last thing to be checked on the crankshaft and then just waiting for parts. Hopefully will have it back during April but we will see when the parts come in. Can't wait! Quote Share this post Link to post Share on other sites More sharing options...

Placid Report post Posted March 12, 2010 torque numbers are impressive They are too high, corrected 15% to estimate flywheel torque. Quote Share this post Link to post Share on other sites More sharing options...

ostoneman Report post Posted March 31, 2010 It would seems lambo have not been far off on either hp or weight claims...if LP is anything to go by. Quote Share this post Link to post Share on other sites More sharing options...
