A long while back we sent over one of the first produced JMF Drag intake manifolds to our friends at Turbo Trix Racing to be tested on Bean's 600+hp 10.0 race car. Well, summer kicked in, and busy season came about for everyone in the industry and then there were a few set backs here and there which prevented them from testing the intake. No problem though, as we at least had track data from a few of our customers reporting the gains they saw--one being our sponsored DSMer that most of you know, Jake Montgomery/evil_eagle. Jake jumped from an 8.9* ET eventually down to an 8.6* using our new Drag intake as well as a few other upgrades over the winter. Gaining that much of an ET jump at that low of a time already requires quite a bit more power than a car going from say, a 14.0 to a 13.5 ET
However, people still wanted dyno proof. Well, this past week, the Turbo Trix guys did a bit of testing on one customers car with a few intake manifolds, including two of ours. The drag screamed results as you'll see below.
Testing was eventually cut short due to a timing belt issue that started to arrise, so they didn't get to lean the car out at much as the other runs and power was cut a hair short of what it could be, but we're quite happy nonetheless. The car used only had intakes swapped and no other changes except for fuel table adjustments from leaning out. The boost was set in the mid 30s with a TTR 35R kit and was the same for each run. Tuning was done with a Haltec ECU, while intake was accomplished through a 4" cold air pipe and BR FMIC.
As you'll see, spool-up was faster with the Drag intake (red lines), and shortly after 5k rpm the drag intake torque and hp just took off seeing approximately a 40hp/tq difference between the two. The peak HP was a pretty consistant 14+hp difference, which once again could have probably been increased with more tuning and leaning out.
Hopefully these results put people's questions to rest on why they should spend a little extra on the Drag intake (aside from the extra time it takes us to build one) when they're looking to squeeze out as much as they can with their setup. Thanks for reading!
