Nitrous-Fed Hemi Ram vs Rob Dahm's 4-Rotor AWD RX-7 // THIS vs DAHM

Castro has a lotta experience racing his Dodge Ram and he’s got the setup to prove it. Viking coilovers all around, fat Mickey Thompson tires, and extensive plumbing for two BIG bottles of Nitrous. But did @RobDahm do some secret tuning to his Hoonicorn-inspired, home-built 4-Rotor Mazda RX-7?

So much can happen overnight with a tune! This was going to be a fair race but it got moved to the second day of filming and i spent all night looking at the logs. Im definitely preparing to race the bigger cars with my bigger turbo!

I'd be working on a tune too if my six figure one-off got dusted by a 4 seater Audi Sedan.

First time I’ve really seen the 4 rotor actually gripping and running well in drag races. It’s always been races where something goes wrong every run and now the car seems like it’s actually controlling the power it already had.

he’s just racing a vehicle that is significantly heavier and makes less power. i don’t think anything is any different at all.

@@el00hel the heavier car actually got better traction at the start by having more mass pushing down on the tires, its not to say rob dont got traction but his advatage is just after the start going in to #2 gear. that might be a part of why the blue audi he raced seem to hook up better in the start and he had some power also down the stretch.

losing two races back to back changes a man haha

[@Yaz27]

@Rob Dahm honestly the trial and error is one of the best parts of a build like this, and is one of the reasons why I've been hooked on to this series for so long. Just inspired me to plan to build a car that has the same concept of the 4 rotor, except with an engine with even worse reliability (if it can even be built): an '04 Impreza with 2 EJ20's connected together to make a flat 8. Although that has to wait until I am actually out of college and have some spare income, so it won't be starting until 10 years later haha

This is why I want to have a WRX STi one day, and then while watching Rob's videos I said to myself "wait a fucking second, I have an idea!" And this whole mid-engined, flat 8 Blobeye just came to mind as my "final vision for how far you can push a Subaru"
