I did some more tests yesterday and today in regards to quartermile times and boost correlation.
Data was logged with my usual xgps160 logger with racechrono pro on android. So while the times might not be 100% accurate since the logger and app are not universally accepted I do believe they can be used as a reference between different boost levels on my car. It looks like trap speeds are 1 to 2 mph slower nowadays than what i logged previously. So only seeing 119.x mph compared to previous 120.x and 121.x @ max boost. And with a good launch I am seeing mid 11's. At lower boost (15 psi) the launches are more easy and if done right gets me a high 11 with ofcourse lower trap speeds. Once over 120mph the difference between 14/15 psi and 20 psi becomes more apparent. Like 120-145 taking 1.5 seconds more etc... edit: possibly my spark plugs need replacing after 44k km and might be the cause of the lower trap speed. Will do some relogs once thats done.

Great info, but a bit hard to compare since the launches on some are so drastically different.

Last night i ran deemar in his e90 pure 335i vs my e92 vargas stage 1. Same mods for the exception of stage 2 clutch in my car. Map 6 targeting pretty much same targets it was completely even. No one pulled away no one lost or won.

Came back from the dyno.
Will post graphs later. just to tease you all. FBO stock turbo with meth map 3 349 WHP and 489 WTQ FBO Pure STG1 with Meth map 6 400 WHP and 480 WTQ (16.5 PSI peak) FBO Pure STG 1 with Meth map 6 422 WHP and 500 WTQ (20 PSI Peak) FBO Pure STG 1 with Meth + Race gas Map 6 440 WHP and 568 WTQ (20.5 PSI) have graphs and logs, lots of info, need some time to organize all data. Best, Daniel Last edited by danielescobarg; 09-25-2014 at 01:02 PM.. Reason: Sorry, 16.5 not 14.5 on 400 WHP run |

Ok guys.
So this is how it went. Base run was done back in 2012, with a pre ISO firmware. Very shaky, also because dyno is a Dyna pack, and like most non-inertial dynos, peaks are very noticeable. Also, this was done at 5000 ft, and graphs are SAE corrected with 1.21 CF. Deltas are more important that peaks. Car is a 2012 135 6MT. mods are: BMS 3.5 inch dp, corsa catback, AA FMIC, BMS meth kit and BMS intake. I apologize in advance for the confusion of the runs, we so many that colors got screwed so it’s a bit hard to read. Base line FBO on map 3 is the Solid green line. I don’t recall what boost was running back then since map 3 adjust boost of meth flow. The graph below the baseline is against the car when was stock (dotter red one) the other green and blue dotted were stage 1 JB4 So, stock: 290 WHP and 390 WTQ FBO stock turbo map 3 meth: 349.5 and 489,5 WTQ ![]() The same FBO runs of the 349.5/489.5 is the baseline on the Pure runs (today) this is the dashed green line (lowest one) On todays runs, we did several, 10 IIRC. But I will only show best of the 3 set-ups we tried. First one (solid green) was on pump gas (90 oct) and meth. Boost targets were 14 PSI until 3000, from 3000 to 5500 16.5 and from 5500 to 6500 15 and 14.5. Back when I was doing logs I found that since meth was supplementing so much of the fueling, boost could not be raised before ~3500 or severe ign retard would occur. This run was: ~400 WHP and 480 WTQ. Log of Run: ![]() Second one is dotted green. Pump gas also + meth. But this time tried to max the turbo from 3500 on. 20 PSI target till 6500. This had some ign retard, and would not be confortable using it on a day to day. Meth simply cant supplement the needed octane. This run was: 422 WHP and 500 WTQ Log of Run: ![]() Last run, we put in 104 octane gas. Mixture was about ~85% race fuel 15% pump. Effective octane of 99 octane or so. This time had the boost targets in 20 PSI from 2000 til redline. This run was: 440 WHP and 568 WTQ. Log of Run: ![]() Pure STG1 (various boost levels and fueling) vs Stock Turbo ![]() overall very satisfied with the results. Money shot right here ![]() I think a backend flash will help a lot with AFR, since they are very lean in the mid range. Top end is ok I guess. That’s the next step, luckily its available for this DME. Hope you enjoy the results! Best, Daniel |
