Engines keep blowing up in new update?

just reinstalled after the new update, and 2 of my cars don't function as they did before, they easily over-torque. I've even seen "catastrophic over torque damage" yet before the update they didn't do that, only the driveshafts would snap if I try to launch them :eyes: (one of them over torques in 3rd gear...)
Specifications of the less extreme one:
Gavril Barstow
423 CUI 'Ultra-Thrust' V8 Engine
Stage 3 Performance long block
Ultra heavy duty engine mounts
Four barrel carburator
nitrous oxide injection system
5-speed manual race transmission
(^^^ just incase it's more realistic and not a bug)

 

reduce the power of the nitro boost

 

It happens without nitrous aswell

 

That sounds like a classic case of Nitrous overload to me, reduce the pressure in it or remove it and your engine will last, add NOS to anything it will explode if you turn it all the way up!

 

I used stage 1 supercharger without nitrous oxide, no engine damage.
