335i Dyno at Surrey Rolling Road

Hi guys, I thought I'd share my results of the dyno session I had at Surrey Rolling Road (now) in Farnborough.



i've got the following mods;



JB4 G5 (Map 5 and Map 4 for base line run)

Wagner Catless downpipes

Wagner FMIC

Mr 5 style modded airbox

15L of 96% bio ethanol (the rest tesco 99)



Dyno Dynamics 4wd dyno. All runs were in 4th gear (auto)



So using the autotuning in Map 5 (boosting to around 17.5psi) it made 436bhp and 510lb/ft and the crank.



Baseline run was straight after, which achieved 305bhp and 330lb/ft.







Here are the power figures at the wheels;



Map 5 365whp and 430lb/ft

Stock 255whp and 275lb/ft







Overall I was very pleased with the results seeing as it's a 110whp delta and apparently it's the highest x35i they've seen on the dyno!



I've got the AFR graph if anyone is interested. Cheers



James
