This is what a 50% increase in horsepower looks like

Racing my cammed and stroked 2007 Mustang GT (4.6 3v) against the stock version of itself to see how much of a difference naturally aspirated mods actually make. We also both race a Porsche 911 and the results are surprising!

Yes, NA builds are expensive. No, it’s (generally) not worth it, but something something eye of the beholder… Rough breakdown of costs: - *Cams* $1,000 (127600 + phaser limiters) - *Stroker Kit* $4,000 (4.9L, but only ~9.6 compression ratio [for eventual boost]) - *Exhaust* $1,500 (Kooks LT, catted x-pipe) - *Intake* $2,000 (CAI, TB, Manifold) - *Trans* $6,500 (includes clutch, driveshaft, and axle gears) If you have any questions for me, you can reach me thru my Tazet profile: tazet.com/foureyes And special thank you to those who watch the video all the way through 🙏

"Worth It" comes down to what you actually want to accomplish. If the goal is a dyno number or a track time sure boost it to the sky but if you just want smiles per gallon I think nothing else feels as good as a smooth running NA engine

I’ve been doing this exact same build almost for the past 2 years! So nice seeing other people appreciating this car! Mine is a2010 grabber blue, but the main differences are that I swapped the front end with a 2014, rebuilt the 5speed to be more appropriate, and did a mcloud clutch. I have mine setup for drift instead of drag, but idk how I didn’t find this sooner! Can’t wait to see it as it goes!

Great video. You could change your axle ratio so it would get in the power band faster. Back in the day I loved reading mustang magazines about builds like this. The S197s should be a good budget build now a days.

[@johncorbin4125]

These are some of the best budget cars to get into racing with on track or drag racing. Cheap reliable and fast but after a bit of upgrades to the tires and suspension these things can be very quick. I have an 07 for the track and its stock motor but with the heavy aero and suspension I keep up with porches vettes and lots of BMWs They beat me in the straights but I eat them up in the turns which is odd to say for a mustang lol
