Video: Turbocharged Small-block El Camino On Dyno

HellCamino puts just about every El Camino that we’ve seen to shame – at least on the dyno. It is a black 1972 El Camino “DIY single turbo, cheap backyard engineering special.” We love backyard mechanics and the insanity that can grow from a few hours in the garage after work and on the weekends.

“Hellcamino70” on YouTube posts up many videos of HellCamino on his channel and is very interactive with his subscribers, often talking about future plans of the car or general car talk of specs, awards and numbers.

In this video, it is making dyno pull after dyno pull to achieve maximum horsepower and torque.

The first few pulls prove that HellCamino needs a bit more tuning as it’s running too lean. After a little bit of tuning with the boost at 10psi, HellCamino throws down 451 hp and 570 ft-lb, all while killing the alternator as it spits sparks out as the turbo spools up. Not bad, but he wants more.

As we watched this video, we couldn’t help but notice how HellCamino squats low on the rear end and seems like it wants to jump off the dyno rollers as the loud blow-off valve exhales some pressure. The boost is turned up to 15psi and in the middle of the pull, literally blowing off an intercooler pipe.

After a few repairs, the pulls continue with the boost at 15psi and they decide to call it a day after a few disappointing pulls at 471HP and no torque increase. According to the El Camino owner, “Clearly something is limiting airflow to the engine.” Since then, the team has decided to tear HellCamino down and start fresh for bigger numbers with the addition of a larger turbo or more efficient cylinder heads.

We’ll be anxiously awaiting on an update on HellCamino once the bigger turbo goes on and an E85 conversion is complete…
