Pontiac V8 Forced Induction
Supercharge Your Pontiac — Kits, Parts, and Engines Built for Boost
Butler Performance engineers its own ProCharger mounting systems for the Pontiac 326–455, stocks the complete TorqStorm Pontiac line, and builds engines and engine kits designed from the first measurement to live under boost. One call gets you the blower, the drive, the fuel system, and an engine that can take it.

Why Centrifugal Superchargers Took Over the Pontiac World
For decades, big Pontiac power meant a roots blower sticking through the hood or a nitrous bottle in the trunk. Today, more Pontiac owners choose a belt-driven centrifugal supercharger than ever — and supercharger kits are one of the fastest-growing categories at Butler. Here's why:
| Keeps the classic look | The head unit mounts on the front of the engine and feeds a blow-through carb hat, so most Pontiacs keep a stock-style hood. Big power, no scoop required. |
| Streetable manners | Boost builds with RPM, so the car idles and cruises like a naturally aspirated Pontiac and pulls harder the higher it revs. That makes it easier on tires, drivetrain, and driver. |
| Bolt-on and serviceable | TorqStorm and the ProCharger head units in our kits are self-contained — no oil lines plumbed into the engine. Pulley changes adjust boost without touching the engine. |
| Room to grow | Start with a single TorqStorm on a mild engine, or go straight to a Butler cog-drive ProCharger kit rated up to 1250 hp. The same Pontiac platform scales with you. |
| Modern fuel options | Blow-through carburetors and power-adder throttle-body EFI make fueling a boosted Pontiac far simpler than it used to be. |
Choose Your System
 TorqStorm single kit on a Pontiac. TorqStorm Pontiac Kits Complete passenger-side-mount kits for the Pontiac 326–455 with supercharger, brackets, pulleys, blow-off valve, carb hat, and hardware. TorqStorm rates its Pontiac single kit as capable of supporting 700+ hp. Single Supercharger Kit Best for: street cars, A/C cars, and first-time boost builds. |
 Engineered in CAD: the Butler billet mount ties the head unit to the block and cylinder head. Butler Custom ProCharger Kits Designed and CNC machined by Butler: billet head-to-block mounting plate, ATI balancer and hub setup, crank pinning kit, carb hat, and blow-off valve, with an F-1 series ProCharger head unit. ProCharger lists Butler as a source for Pontiac 400/455 kits. Serpentine Drive Kit, up to 925 hp Best for: serious street/strip cars and race builds. These kits do not work with A/C, and we recommend an intercooler. |

How Butler Builds a Supercharger-Ready Pontiac
A supercharger doesn't just add power — it adds cylinder pressure, heat, and belt load. We build a boosted Pontiac to handle all three from day one, instead of hoping a naturally aspirated combination survives.
| Compression | For our supercharger kits we target 8.75–9.5:1 with aluminum heads on 93-octane pump gas. Compression is set with the piston dish and chamber size, based on your actual heads and blower. |
| Forged pistons & rods | Custom Ross forged pistons are spec'd for boost from the start, paired with Molnar 4340 forged Power Adder H-beam rods (MTE-CH6700VTB-T8-A / MTE-CH6800VTB-T8-A). |
| Power Adder cams | Butler/Comp cams ground specifically for centrifugal boost: CCA-BP9010 for TorqStorm and Stage 1 ProCharger combinations, CCA-BP9015 for Stage 2 big ProCharger builds. |
| Cylinder heads | Our machine shop offers CNC forced-induction chamber work and boost chamber softening to set chamber volume and reduce detonation-prone hot spots. |
| Bottom end & crank drive | Billet 4-bolt main caps and main studs keep the crank in place under load. Our complete ProCharger kits include our crank pinning kit (BPI-PCH-1027) so the blower belt can't move the balancer. |
| Fuel & tuning | Blow-through carbs or power-adder EFI, a boost-capable fuel pump, and a boost-referenced regulator. We can dyno-tune boosted engines here in Lawrenceburg. |

Supercharger Planning Checklist
| Engine | Compression, head type, and pistons suited to boost. Forged pistons are recommended. |
| Accessories | Do you need A/C? That decides between the TorqStorm Plus/Twin A/C kits and the Butler ProCharger kits. |
| Fuel delivery | A blow-through carb or power-adder EFI, a boost-capable fuel pump, and a boost-referenced regulator. |
| Ignition | An ignition that can control timing under boost. |
| Air path | Carb hat, charge tubing, blow-off valve, and an intercooler for higher-boost ProCharger builds. |
