Just got back from VT, after having some testing and power runs done. Car ran fine and showed 250 bhp @ the wheels along with a massive 433nm torque @ the wheels!! hopefully i can post the maps up later .... A massive thanks go to adam and hamish . (especially hamish for holding the fire extinguisher !! ) :B_steerin
LOL, another one with a fuel leak!!! :) I sent you the charts. Adam.
that is very good - over 300 lb/ft !!!!!!
yeah :slap:
only a little one.......
here's the charts

What is it with these fuel leaks?
alrighty, thoso are impressive figures. what have you done under the bonnet if you dont mind me asking.
Power run - was it with or without NOS...?
Indeed, very impressive figures, congratulations. Couple of questions: 1. Did the runs start from 3500 and up, ie the pedal wasn't pressed until then? as I assume the runs were done with the nitrous on and to the best of my knowledge your still on the standard turbo, so the threshold for boost would be about 1000rpm lower, even more so with the nitrous aiding the spool up. 2. Is it just a case of the turbo running out of puff near the end I take it, ie the wheel power is the same(ish) from 4500 to 6500rpm as the torque tails off with the rpm rising, we found the same with Jacqs resulting in high torque with relatively lower bhp (415nm and 260bhp at the fly, wheel bhp peak was 235 but we dont have the curve to work out wheel torque lower down the range) basically due to the boost and torque tailing off. 3. How much gas were you running on top of the 1.3 bar out of curiosity? 4. Whats the spec these days , it would save all of the above questions :P lol Again though, very good figures. Ross
one day you gonna have to show me where vt is

Ross[/QUOTE] cheers Ross!! i was reluctant to start the run at lower rpm for saftey with the nitrous. we tried from 3000 i think but it was basically the same. i.m not sure about the torque drop off, might be due to the timing advance from the ecu ? one of the reasons for the dyno run was a problem with the boost backing off but we seem to have sorted that one! the fuel leak was from the nos distributor pipes and was sorted after some tinkering. i guessed something somewhere would happen - it hasn't run since august! the last graph is without nos and the first the direct comparison with and without. the spec is still the same as before - standard turbo and 50 bhp rated jets on the nos . although the exact jet sizes which produced the perfect air/fuel ratio will definately remain top secret! darren- i meant to say i was going but forgot ! sorry :slap:
no probs matey i was up north on business today anyhow next time eh?? need to get mine on the dyno and checked out
Great news Jamie!! Thats a storming T4 you got there!! I bet your chuffed to bits with her!! Looking forward to seeing her at the strip out performing alsorts of exotica (and a few T5's lol) x
Very impressive runs Madness, The S40 are great looking cars, better than the S70 IMHO, Can't wait too see her in March :) Gary
I saw her today hehehehehehehe very nice work under the hood

Cheers for the reply and posting the graphs etc. Ross
not a problem ross. i was just pleased to see the figures i guessed it must have had.
