Even as a race car. I would not drive it back to the pits or anywhere without filters. You will have to tow/push it everywhere except down the track. That means you’re going to be compromised by the airflow limitations the filters. I’ve seen a number of Pro Mod level cars feeding big turbos thru the rear of the hood.

Pulled the big conical off my DragPak Whipple and replaced it with a bell on the dyno. Saw +70 rwhp. Driving around…. You’re right. Never.

I think all’s good until you hit the airflow limit of the filter (there has to be one) and it becomes a restriction. On a 1000hp engine it’s getting all the air it needs with that filter. Then as the power goes up, it’s going to need more than what that filter flows without restriction and it becomes a big limiting factor fast. My engine is a 426 seeing 25 lbs boost at 7200 rpm and found that limit. The original point was concerning the Hellion turbo filters. Absolutely necessary considering where the turbos are. The Sipple Hellcat with Barth tuning just ran 7.70 at 180 mph on the small Hellions. That car is a 4000 lb 8 speed/IRS. We’re talking 2000 hp to do that. I didn’t think that was possible but here we are. There was no mention of nitrous so with benefit of the doubt given…. there wasn’t any.
