This Dual Compound Buick V6 Is A Study In Daring To Be Different

Now this is some hot rodding right here, kids! How about a Series 1 Buick V6 with four, count them, FOUR turbochargers on it plumbed in a dual compound style setup. The vehicle this is all loaded into is a 1959 Austin Lancer which you wouldn’t be familiar with here in the USA as they were not sold to us. Nope, this car is in Australia and the machine makes about 400hp to the tires. Now before you go all Smokey Yunick on us and say that it is lame to have such a “low” power figured out of this setup understand a couple of things. The first is that the engine is 100% internally stock. The second is that this setup was apparently finished about three hours before it was plugged onto the dyno you will see it run on in the video. There’s more gusto here when the builder is ready to wick it up. From the looks perspective, few things can touch this little beast!

As many of you know “compound” turbocharging is just like it sounds. You have a large turbo that serves as the “atmospheric” turbo sucking air from the outside and force feeding a smaller turbo which in this case is seeing 14psi before it compresses the air again and sends it into the engine. We may have missed it but we’re guessing that the engine is seeing 30psi or better by the time the air is shooting out of the smaller second turbo. Note that there is no intercooler so that intake charge is plenty hot by the time it makes it to the throttle body but again, this seems like an engineering exercise and something that is just beginning to get sorted out. The owner said that the best run on the car is an 11.6 in the quarter mile but we’re thinking that was with the previous setup before this. The timeline of completion to dyno in this video doesn’t allow for a visit to the track.

The car itself is a neat little package. Very reminiscent of gasser era cars like the Thames, Anglia, or even the Austin models that were sold in the USA it has a neat styling and looks cool with the big meats hanging off the back of it as it does here. Sometimes we need to look past huge power numbers and tug boat torque to celebrate people doing something interesting and fun. We’re thinking that the Buick crowd here in the USA will dig this setup.

Also, when it is last time you saw a compound turbocharged gas engine? Diesels by the dozen but I am not sure I have ever seen a hot rod gas mill (especially a V6) with a compound setup on it. Interesting!
