    HPF Stage 2 M3 137-139 mph traps disproved

    We have seen many users and HPF fans alike on various BMW forums touting the 139 mph trap speed achieved by Evil Twin Robs HPF Stage 2 M3 at the Spokane Motorsports Drag Strip.

    Often when there would be a conflict or questions as to how fast an HPF car is these 137-139 mph trap speeds would be used to prop up HPF cars when keyboard racing. Recently, Evil Twin Rob ran at this same track after the suspect timing equipment had been replaced and his traps were over 10 mph less than what was achieved before. This large of a variance shows the previous suspect times were inflated and not accurate. The track was not NHRA approved when the runs were made.

    For the record, Evil Twin Rob has done nothing wrong and is an absolutely stand up guy. However, these 137-139 trap speed runs can no longer be used as accurate representation of the HPF Stage 2's capabilities. It seems we have a clear explanation now of how a Stage 2 could be out trapping Stage 2.5's as well as having such a large variance from other Stage 2's. This is in no way the fault of Evil Twin Rob and we commend him for actually taking his car to a drag strip and stimulating a large batch of discussion on the capabilities of HPF cars.

    For whatever reason, something happened to the timing equipment at Spokane after 2006. This run was made by Evil Twin Rob in 2006 on race gas:

    This is fairly accurate we believe for what a Stage 2 is capable of, 132 mph.

    These runs were made in September of 2008 after something happened to the timing equipment, also on race gas:

    These are the most recent runs on pump gas with meth after the timing equipment was replaced at Spokane:

    Even if he ran on race gas and meth he would not pick up an additional 13 mph in the trap and at most would be approaching the 132 he hit earlier. BimmerBoost commends Rob for going out to the strip and sharing these results for the benefit of the BMW community and not hiding them to attempt to make his car look stronger on paper than it is in reality.

    Oh wow! That's a huge variance though, I wonder what the cause was? Was their equipment really that faulty to show such a huge margin?

    Thanks for going out there and clearing everything up Rob!

    Exactly, he deserves major props for going out there and posting the results each time.

    Yes, if the equipment is faulty it can show huge variances and they saw the need for new equipment.

    Yep, pretty impressive numbers none the less. Was he running DRs or streets, I am guessing by his 60's that he was runing streets.

    He is running 305/35/18 MT ET Drag radials.

    Im thankful Rob did this. It shows his car is capable of 130-132 traps on race/meth mode. However the 137-139 he ran before were just track timing errors. Imagine how many people (other cars) are boasting their numbers from that track without anyone realizing its not accurate.

    This is what sucks about 1/4 mile tracks, how do we know what track is 100% accurate? We see freak times in some East Coast tracks but never discredit them. This is clear case we caught because it was inflated alot, what about tracks that might inflate it by a couple mph that we dont really care to dissect? We see very low times in most west coast tracks compared to east coast tracks. Yes DA makes a difference but sometimes the difference is pretty significant.

    Well said.

    NHRA tests the timing equipment and that is how you maintain NHRA certification.

    You see freak East Coast times due to the ridiculous negative DA. Once you adjust for the DA, the times are no longer freaks Click here to enlarge Also, tracks like MIR are actually prepped well unlike our West Coast tracks.

    Wow, he could still run really low 11s with a decent launch. He must be pushing so much power he is still smoking the DRs somewhat with 1.9 and 2.0 60s. Pretty incredible car.

    Seems you have to use an NHRA or IHRA registered track. Indepently owned tracks don't fall under the same rules. Unfortunately, the NHRA tracks have relatively strict safety regulations.

    I knew this didn't make sense. Rob is a stand up guy. Even his use of 17" 275/40/17s didn't make up for any gearing difference that could lead to a higher trap speed as he bounced off 4th a few times.

    Are you referring to the safety regulations?

    He isn't saying it is unfortunate to be safe but that you need to conform to certain regulations when cross a certain threshold on NHRA sanctioned tracks. This means the installation of a roll cage that meets their standards as well as a fire suppression system I believe. That is what he means by unfortunate, having to add a cage when you don't necessarily want to in your street car.

    I've always wondered about this! I did notice in his vid that some places his car saw ~15psi of boost. I always thought that may have had something to do with it.

    The high boost is really interesting as well and a few people have pointed that out.

    Right.

    I remember back in the day when Robert asked HPF to test the limits of the stock motor. I believe he made like ~720whp with like 22psi. BUT, that was just for $#@!s and giggles. It was never left in that state.

    Would be cool to see what it could do with a thicker head gasket.
