Dynamic Racing MAXflow Stage 3 Heads
Already installed big turbos, fuel system, exhaust and boost controller? Still want more power? Want to make big power without having to increase boost past "pump gas" limits?
With 8 of the top 10 Quickest/Fastest ¼ mile 3000gt/stealth cars in the USA all are running DR stage 3 heads for there fastest times. Need we say more? > Off the shelf DR-stage 3 heads helped power Matt Monett's 93 Stealth to firstname.lastname@example.org in the 1/4 mile. Once again setting the world record for a stealth/3000gt, the ONLY 3000gt/stealth in the 8's or over 160mph in the 1/4 in the WORLD.
You will notice a huge increase in top end pull at the same boost level.
The Stage 3 Heads Include:
- 1mm Oversized Valves are back cut and swirl polished for increased flow
- Fully Ported Intake Ports
- Fully Ported Exhaust Ports
- Enhanced Bowl Configuration
- Proprietary Valve Job
- New Valve Springs
- New Valve Seals
- Factory Casting Flaws Removed
- Reshaped Combustion Chamber (Unshrouds Valves for Better Flow)
- Combustion Chamber Flaws Removed (helps prevent detonation by removing hot spots)
Expect gains of up to 60hp at the same boost level you are running now, depending on application, and if the turbos you are using have enough flow left.
Option: If you plan to go with upgraded camshafts we recommend the High Rev Valve Spring Kit with Titanium Retainers.
