Someone's Built A Monstrous 8.5-litre V12 From Two LS1 V8s
This huge V12 was created by grafting together two cut down General Motors LS1 V8s and adding a custom crankshaft
The result of this mad project? 707bhp at 6300rpm, and 627lb ft of torque at 5700. It’ll be heading to a customer in the USA, who’s apparently planning on squeezing it into the engine bay of a Chevrolet Camaro.
All this has us in mind of an amazing project we spotted a couple of years ago, which saw one heroic hot rod builder stick together two 1JZ straight-sixes to make a one-off V12.

diesel v12 next?
why not v16 i mean u have 8 and 8 why cut it
So why not get a Viper 8.4 and tune it to 700 hp?
because no
I can applaud engineering and commitment to something like this. However, you can achieve the same power goals with a few modifications and forced induction, and probably be more reliable. Certainly a lot cheaper. I guess some people just want to say they have a V12.
Making a V12 is more unique than putting a charger on it.
Honestly, not overly impressed with the power figures. V8s come out of the factory with that much nowadays. From a custom V12, I’d have expected more.
This is just the first one and they don’t want to push it too hard. I’m sure once they crank out a few more and do some real tuning on them they should be putting out near 800hp possibly more.
Naturally aspired engine. Pushrod valves. This is as expected.
thats fun but it’s totally unbalanced and why not take an old Mercedes or a bmw v12 and boost it?they are going to make a ton of power
EmilBlum Wow
They should call it an LS1.75 lol
And no random cat was spotted
I don’t get why they had to use V8’s and cut them down. Why not start off with two V6’s to begin with?
Yea I’m just thinking about that. If they have 2 v8s why they don’t make a v16
That’s because the cylinders at one end of the cylinder bank are different than the cylinders in the middle. Think about the coolant, oil chambers in the block, the head gasket, valvetrain, etc. They wanted to keep the design of the middle cylinders, that’s why they needed to cut off the end bit which is different. It’s really challenging to describe clearly, I hope you can understand what I mean
