Something we’ve never done before…

We’re launching the SPE Motorsports S650 Twin Turbo Kit as a Lethal Performance exclusive!

Here’s why this matters: This is the first twin turbo system that doesn’t make your engine bay look like a science experiment gone wrong.

SPE spent years perfecting this mid-mount, factory-style setup that installs cleaner than most supercharger kits.- 600-2,000+ HP range (your choice)

- 3-50 PSI adjustable
- No oil pan drilling
- No permanent modifications
- Complete bolt-on installationThe catch? We’re the only dealer who can offer it.SPE builds incredible systems.

But they built this one for us to bring to the S650 community first.
Who’s ready to make their Dark Horse actually dark?

Think you're ready? Check out the kit here ---> Lethal Performance Exclusive SPE Motorsport 2024+ S650 Mustang GT/Dark Horse Twin Turbo System

Nice. I'll be watching for fitment and installation on this for sure.

First look at the pics and I see what looks like a mish-mash of AN and worm gear clamps. Given some of those oil lines are on the bottom of the car...I'd really hope to see insulated and full AN. Some of the wiring looks a bit worrying without more insulation or heat wrap on it.

Actual hardware looks well sorted. Welds look clean and all of it is well routed, except maybe the dump pipes, which if the underbody is put back on might cause some issues, particularly without more insulation on the oil lines and wiring.

That all said, for $9k+installation looks to be quite a good deal, IMHO.

RSA had a 2000HP wheel rating a couple of years ago on their twin turbo project. There were some great internet videos of it slaying anything that came near it.....lambos, you name it. I didn't read the literature but you will need engine and that kind of HP. Fun though!

Watching with great interest. Would be very helpful to know from Lethal what fuel pumps/injectors would be needed at what Boost points. For example, if I'm pushing a conservative 6 psi of boost for maybe ~750 HP, would the duty cycle of stock injectors experience clipping under WOT? If so, would 4 psi be the line? 8?

Injector Dynamics sprayers look to cost $3k, much less $700 for a Tetrad and then up to four pumps on top of that... Jeezum. Talking $14,000+...

But if I could boost twins to up to 8 psi for up to ~800 on stock injectors and pumps for $9,000, plus a tune from Lethal that I could load onto my MPVI3? It's the first turbo solution that might get me off the Whipple bus I'm riding on as I save pennies up...

With the Helion apparently the twin turbo set up can apply 5-6 boost PSI on stock engine, no tune, no fuel pump from what I was seeing on youtube

We should have all of that information coming soon. We are hoping to have the kit installed on a bone stock car first, and then we will take steps from there on what would be recommended or required moving forward. As soon as we have more info, we'll definitely report back!

Lethal, you ever gonna show off a build with this kit? I was impatient so I went with the Whipple because it came first but my handle is GhastlyTT and not GhastlySC for a reason and I'm itching to convert.
