More and more people keep pushing the limits of the stock block, and you don't hear of any blowing up is it safe to say they can live in the 800 to 1000 hp range

I believe that 800-900 is perfectly safe on a turbo car that is tuned properly for the stock engine. 1000 is starting to push it but so far we have not seen any issues.

Of course all this is speculation at this point and pushing the limits on factory components is always a risk

Any engine (even cast and powdered metal components) can be made to produce a ton of power and torque. The issue is tolerance.

You can take a Kia and dump 20 psi onto it and make big numbers, as long as it's TUNED perfectly.

Where engines get nuked is all the variables in the equation. Bad batch of fuel, varying street conditions with loading, throttle position, gearing, etc.

The stresses seen on the rotating components grow exponentially with outlier load cycles. Meaning that just because something can be tuned to make a zillion ponies on a dyno in a controlled environment, doesn't mean it's suitable or robust enough to handle the inevitable variances you might encounter in daily driving or spirited street driving or harsh track duties.

I guess what I'm saying is it's kinda like how many people can you fit in a boat? Just because you can put 30 people in a 12' john boat sitting still on a pond, doesn't mean it's safe or recommended to tell everyone the capacity is 30 persons for many/most conditions the boat will see for typical use.

People get hung up on the amount of "boost" but it's really the torque created that's the bigger danger. Predetonation is always a bigger issue with higher compression engines, so the voodoo is already limited in how much boost you can safely run (with a given fuel), but in terms of power/torque, I would say the engine can handle a lot, but can it do it reliably on the street in varying conditions?

A stock transmission can handle quite a bit of power, if you baby it. If you're rev dumping it and power shifting it, even stock power levels are going to stress it beyond what it can handle.

@FatFab folks - Car is awesome! Quick question: the turbochargers look to be lower than the oil pan, is there an electric oil scavenging pump or did you folks manage to drain into the pan? Weighing a PD blower vs. turbocharging in terms of reliability. Thanks!

Yes we have a custom scavenge system we built that works very well mounted low like that. It returns to the front timing chain cover.

Thanks Ben! Great to see a local company doing work. I'm fairly sure I've come across one of your customer's cars on the way down to Bloomington.

Thank you! And which car was it? We test drive up and down hwy 37 pretty frequently

Is this kit exclusive to your shops or would you ever consider selling and shipping a kit to customers for their own installation?

Right now we are not planning to offer this as a kit to be installed by the customer. It will be a package deal offered through us and eventually through other dealers.

Aren’t these blocks sleeved now ? To eliminate thin walls .

All the blocks have a sleeve in them from the factory, they are aluminum castings with ductile iron for the GT and the Voodoo uses plasma arc liners. When building an engine like this we have to use an aftermarket sleeve with more meat for strength and the ability to hone it for different size pistons
