Not Best Day on Dyno

747flyboy · 11-13-2016, 09:43 PM

Recent ALPINA MGT2259 Turbo upgrade Garrett Part Number 803709-5007S
OE Part Number 1165790AI02. Were able to generate 562WHP but not impressive torque numbers. Problem; Tires, original tires at 19K since acquired vehicle. Did not have sense to install newly purchased set of PSS, hence tires kept spinning/slipping on dyno wheels (see discontinuity on Dyno graph around 530WHP followed by a power loss dip and crest again). Car performed marvelously and should have been 600+ results. According to Dave at Complete Performance in Atlanta (Dyno Shop) this car should have been 600WHP plus without hesitation. He was thoroughly impressed/amused despite obvious wheel slip on dyno wheel, managed to produce such results.

I have attached JB4 log as a reply, note at 5400 RPM peak PSI was 20.6 (restricted by 5 Volt 2.5 BAR TMAP sensors and exactly as advertised by Garrett achieving peek Horsepower at 5200 RPM. This set up has a potential greater than 630WHP if we can get burger tuning to flash firmware using 3.5 BAR TMAP sensors to peak these turbos north of 28PSI and unleash the potential of this engine. Trend is only upwards

Hi there...Everyone else is telling me....Crazy AFR'S and such. Still on straight 100 octane (tried E40 mixture 100 octane) however, intermittent "drive train malfunction" code 122104 "no description l". I went back to straight 100 (dyno on 100 octane). Any ideas how we can rich AFR with present MAP7 arrangement? So far no issues with injectors or HPFP, although I have a feeling Low pressure Fuel Pump is about to top out possibly due to E85 mixture.

Nice numbers, have the CSV for the log file?

I want to take a quick look.

Hi Matt,

For some reason I am unable to upload excel format. Here is my link posted at N54tech with .csv log.
