SP72 Posted September 11, 2019 Share Posted September 11, 2019 Look like impressive gains! 18bhp, 15 or so lbft? Flywheel torque looks low for a 3.4? The before figures look very low. Mine in 3.4 guise was 245 lbft on Waynes rollers. Did you calculate your torque from Waynes figures? You taking it back to Waynes for a comparison?

Busybee Posted September 11, 2019 Share Posted September 11, 2019 264.5 hp Chris. .1 more than mine at Wayne’s 🙈 Link to comment Share on other sites More sharing options...

I got no response back from Wayne only his chart that showed the BHP. Not sure I will it’s a long way up north. Link to comment Share on other sites More sharing options...
Jonny Hart Posted September 11, 2019 Share Posted September 11, 2019 BHP and Torque are linked by stuff you hated at school called maths. HP = Torque x RPM ÷ 5252 Usually they plot both on the same scale which results in a crossing of each line at 5252 RPM (because maths). You can always calculate one from the other!

Stick that formula in a spread sheet with an incrementing RPM in the first column. If you know the Torque values from a dyno plot, enter them in the second and the formula will calculate the HP. Or the other way round if you know HP and want Torque. Link to comment Share on other sites More sharing options...
SP72 Posted September 11, 2019 Share Posted September 11, 2019 Ah, I see - you plot the torque graph, not just calculate peak torque - thanks! Now beaky just needs to know how to calculate rpm from mph to obtain torque from Wayne’s graph Link to comment Share on other sites More sharing options...
Richard Bernau Posted September 12, 2019 Share Posted September 12, 2019 Well, he has the 6000rpm point already if I read that right. 249 = tq x 6000 / 5252 therefore tq at 6000 is fractionally less than 217lbft. Wayne is a bit funny about giving graphs out. I guess he thinks his job is done once its all optimised and the customer should drive away happy knowing its optimised and that is the end of the story. He has probably seen so many dynos all over the country that he knows they can't be compared and that the numbers are somewhat meaningless - ie., its just a useful before/after comparison, not an absolute. But he forgets that we need internet fodder for very worthwhile and lengthy discussions and bragging rights! Link to comment Share on other sites More sharing options...
ras62 Posted September 12, 2019 Share Posted September 12, 2019 Am I understanding things properly, before at Wayne's 263 @ crank and with all these mods 264 @ crank?😕 Link to comment Share on other sites More sharing options...

Busybee Posted September 12, 2019 Share Posted September 12, 2019 For a 3.4 with trick bits, would you expect another 20hp or so? Link to comment Share on other sites More sharing options...

Peak torque extrapolated from that plot shows 245bhp @ 5500 (98mph) using a 7200 rpm limit which equates to 234 ftlb. This latest tune has lost 20 ftlb of torque!

ras62 Posted September 12, 2019 Share Posted September 12, 2019 The dyno plot from Wayne was the engine optimised in its origianal configuration before mods. This can be compared to the later plot with mods and again optimised. The mph reading on the WS plot will be the same as the x axis RPM plot on the later chart unless the rev limit has changed. THe shape of the torque curve will be the same which shows a peak arounf 5500 rpm. This 5500 RPM would be about 98 mph on the plot from Wayne. At those revs Wayne was recording about 245 bhp which gives the 234 ftlb figure. If the rev limit on the WS dyno wasn't 7200 and was in fact say 7000 then the torque figure would be very slightly higher. Link to comment Share on other sites More sharing options...
Beaky Posted September 13, 2019 Author Share Posted September 13, 2019 I’m away at the moment, will up date later but the torque numbers on their graph are wrong and will be corrected You can’t compare one Dyno to another as as setting vary resulting in different numbers The red line is Waynes tune on their Dyno, the black after the kit and tune these are where the comparison can be taken Steve has also told them to up the Rev limit to 7k which will help just a tad. As Richard says these are just numbers it’s once behind the wheel that counts, i’ll Know on Monday Link to comment Share on other sites More sharing options...
Beaky Posted September 15, 2019 Author Share Posted September 15, 2019 OK to number junkies, this is the revised chart. I'm picking the car up tomorrow, so the real test starts then. Link to comment Share on other sites More sharing options...
ras62 Posted September 15, 2019 Share Posted September 15, 2019 So no improvement on Wayne's figures despite all the mods? The before figure can't be as it left Wayne as with those mods it wouldn't work with Motronic. Link to comment Share on other sites More sharing options...

You just don't get it, The black lines are Waynes tune but measured on SC Dyno, the Red after the kit! and on the same Dyno................... YOU CAN'T COMPARE READING FROM DIFFERENT DYNO'S AS MANY ON HEAR WILL TESTIFY TOO! Do you have shares in Motronic, and do you still think the world if Flat.
