Modalworks M177 Hybrid Turbo: quick spools with big power
The Modalworks stage 2 hybrid turbo (dubbed the MW2) packs a big punch yet looks completely stock from the outside. Our design doesn’t just swap the compressor wheel, but also extensively machines the exhaust side to fit a large 9 blade turbine wheel. Our specific combination of turbine and compressor upgrades make for an extremely balanced hybrid turbo.
These MW2 turbos spool consistently spool as fast or faster than pure 900s but flow like pure 1000s. This design yields a setup without tons of turbo lag and still packs massive top end power.
- Made in the USA 🇺🇸
- Custom designed 5 axis point milled billet 6+6 compressor wheel
- CNC machined and ported compressor cover
- Oversized Inconel 9-blade turbine wheel
- CNC machined turbine housing
- Coated exhaust manifold for rust prevention
- Completely rebuilt CHRA with Borg Warner OEM bearings
- Entire assembly high speed balanced and professionally assembled
In stock and on sale now, get the best of both worlds with a quick spooling turbo that has big flow potential.
Prior to the dyno, we compared Pure 900s to our turbo directly on the same vehicle, as well as reviewed numerous logs from customers with their Pure1000 to give a comparison of how the hardware compares as seen below.
What this means is that our MW2 responds incredibly fast with tons of upward flow potential. We accomplish this by not just shoving the largest compressor wheel possible in the housing. Other companies advertise very large wheel sizes above 72mm with a small to medium sized turbine wheel around resulting in a compressor to turbine ratio of 30+% (not great). We don't think this is the best approach because you inherently create a mismatched turbocharger... our main focus was to create a balanced setup that spools fast and keeps producing all the way till redline. Most turbo design guidelines recommend the ratio to be within 10-20%, exactly where ours lies.
Additionally, in the graph below we are easily able to maintain 29psi all the way till redline while hovering in the 66% WGDC regime. Plenty of untapped flow potential.
We plan to take this car back to the dyno once the trans is built and push the turbo to the limits, but for now we are exceeding the torque capacity of the 7sp transmission.
The 722.9 is a really nice transmission that can be essentially bulletproofed to whatever typical mods most folks do on these cars, within reason. The drums and casing itself are very very sturdy with remarkable reinforcement compared to lesser transmissions. You don't get something for nothing of course, and the additional reinforcements and use of better quality parts, steels and friction materials costs money as well as someones time to put it all together, etc... In addition, the additional reinforcement will somewhat increase drag on the mechanism and contribute to additional parasitic losses at the driveline depending upon what is done. Same flywheel HP at motor, but less WHP due to greater losses, contingent upon how much is done.
Anyway, hope this helps.

We recently did some logs with an aggressive tune and were easily holding 35psi with moderate wastegate duty cycle, so these turbos can move some serious air. Remember, these have upgraded compressor and turbine wheels unlike some products that only touch the compressor wheel.
