Small Twin Turbos vs Supercharger - School me Please

Understood. It's just a preference, run what you like it makes no difference to me. FWIW my LS2 engine is N/A with a carbureted intake manifold, a Holley throttle body EFI and great big old school air cleaner, everyone said don't do it like that it'll never work right. In reality it works rather well and gets a lot of attention and even more people telling me they love it. I'd upgrade the engine with a Whipple while the car is down with a new chassis build, but I used cast pistons to save some money and I still run 930 CVs so boost is a no-go for me. I don't really need any more power anyways, most of the time the 450ish HP my engine makes is plenty. :cool:

I honestly prefer supercharger as well, but mainly because there’s zero waiting on power.

But… Turbo is king of going fast.

One of the guys we used to dune with has twins on a 406 in his Tatum, it ran good when all was good but there were more days when it wasn't right and it ruined more than one dune trip for the group. It was professionally built and tuned. Had the engine out with the heads off a few times, retuned a few times, now he's building a new engine with aftermarket block although I don't know all of the details.

I just don't like turbos, a feel a supercharger is better all around for driveability. The torque down low is a better tradeoff vs making power at 6500.

2 of the Whipples we installed this year, both pulled the Turbos off they spent all last season, trying everything, went to small sizes, bump up compression, and the owners said for they way they like to drive, the supercharger was complete different feeling then the turbos,

I think with the displacement of a V8, there really isn't a need to go turbo to make duneable power goals.

Unless you like the way turbo drives. The power delivery is certainly entertaining. :cool:
 
We replaced them every 3 years in the TT drag car I worked on, we ran leaded C16. We we replaced them not because they were acting up but to make aure we got good data. We don't think one of them died, just part of the maint.

Same, except mine was a Time Attack car, so saw a lot more miles. It was an annual replacement type thing.

Biggest thing is making sure they're not on the lower half of the exhaust pipe where moisture can collect in them.
