Turbonator reviews?

Any of you fellas tried one of these fancy mechanical VGT’s from DPS in Salt Lake City? Been out for pickups for a few years now and had good results, but I can’t find much for us big displacement owners

 

I tried the switchblade........made it 8 miles and turned around to take it back off. Saw turbo inlet temps well over 1400 degrees with a light load at 1500’ elevation. I couldn’t imagine what the pyrometer would say running through the mountains with a decent load on! This other turbo is similar to Holset VGT’s, but designed to handle soot from our older engines. Variable exhaust housing from 0.7 A/R all the way up to 1.7 A/R to really let the engine breath......in theory

 

He didn’t want to send me a 78 mm, said the 75 mm was plenty big. I pulled a 78 mm off to try his and it wasn’t worth it. He’s arguing with me now that there’s something wrong with my engine.......but funny enough it runs just fine with my old turbo back on again. Just didn’t feel like the engine could breathe with that other conglomeration hanging on the manifold

 

Any idea what you’re making for hp out of the B model?

 

I used to have a 1994 379 Pete with a C model in it. Wasn’t a PEEC engine, just a good ol’ mechanical. Ran right with most of the new 550 E Models of the day. With the right parts and a good pump guy they’ll run real good!! Ran a lot of critters across the country with that engine! Are you guys still running the big mechanical exhaust manifold?

 

I had the same thing with that switchblade on my truck. Lost nearly 10 psi of boost compared to the 78mm that was on it. If it was a bigger frame charger I’d be ok with that as long as it was moving the volume of air needed, but those high egt’s tell me that wasn’t happening either
