SH Engine PT28XM1-P8 – Too Powerful To “Sshh”

via SH ENGINES / 佶宏實業.

Be afraid… be very afraid… The PT28XM1-P8 by SH Engines is one mean engine that should have been branded something else. The “SH” branding sounds way too modest for something it’s caliber. A rich hobbyist could possibly found a brand on this engine and actually get away with it.

Suppose, we call this the Demon Engines’ Speed 28 XPR… That’s alot more likely than its current too-convenient label (rather than a name) that doesn’t tell you anything other than it being a .28-sized engine.

SH engines are touted to be extremely powerful and reliable in their class, and this model is no different. The 4.57cc 8-port big block offroad buggy/truggy engine also features a high maximum RPM of 36,000, and a whopping 4.0 horse power. That not only means a high maximum power, but a high top-speed too. Just for comparison, the HPI Nitrostar 4.6 on the HPI Savage X only generates 1.9hp @ 28,000 RPM – but it’s also that low because it’s supposed to be for high torque. However, the SH .28 truck engine produces 3.3hp @ 28,000 RPM, hence hobbyists are going SH. The PT28XM1-P8 is currently the flagship range-topping engine by the Taiwan RC engine manufacturer.

I recently won an Ebay auction for this engine at a rock-bottom price, and I’m certainly looking forward to receiving it. This will be the new power plant on the Kyosho Inferno MP9 TKI I took over from a friend. I support Asian RC products.
