Harrop Eaton TVS Supercharger

Harrop is purportedly looking into applying their 2GR Supercharger to the FKS engine. They've been playing with forced induction 2GR engines for many years. Hopefully, if it comes to fruition, we get the TVS 1900 with the fat intercooler.

Some nice info about their current 2GR products can be viewed in this video.

I had a dream about a supercharger last night.

 

It’s one thing to physically put a supercharger on but it’s a whole new beast to tune it. Magnuson is/has been working on theirs for years but they aren’t able to tune it

 

I suppose we'll have to sit tight and see what comes along. Miller cycle? If this was known as a definitely happening, I'd pick up a a low mileage long block and begin prepping it.

 

Hopefully they can get something together. Seem to do a few Toyota’s from the Facebook so should be able to handle the tuning.

 

Atkinson CAN NOT be supercharged. All that extra air pumped into the air intake has no value when the intake valves are still opened...

 

The 3.5L engines Atkinson cycle is a “simulated Atkinson cycle” using VVTI, it’s not a mechanical function of the engine valving or cam design. If the supercharger contained a tune that disabled this program, then there is no reason it couldn’t be.

 

Atkinson cycles LOVE forced induction. They need a positive displacement form of aspiration for it to work properly.... it is then called a Miller Cycle Engine.

 

Yes, you would have to delete that Atkinson function entirely, and you would get 2mpg from then on.

 

Miller Cycle.

The shit that's posted on here just makes me laugh lol

 

I know right. Where’s YOUR FI 3rd gen Tacoma...

 

If you'd like to learn the basics and why people are commenting about the miller cycle.

 

Atkinson cycle is a mechanical function and not electronic.
Holds the intake valve open a bit more and is controlled by the cam shaft hence VVTI. How can you delete that???

 

They aren't deleting that, and there's already been supercharged Atkinson examples coming from Mazda at least.

 

Turbo Atkinson from Toyota. Every time a new engine or new emissions standard comes out people start screaming it's the end of modifications, and that always turns out false.

 

Atkinson, Miller...all bandaids to save a bit more gas and make cars 2x expensive.
Just bring back the Otto engine.

 

Well that I fully agree with you on.

 

Nobody said it was impossible. But just like in other threads...why do you think magnusson all but gave up on the whole concept? The headache isn’t worth it on this aluminum can engine. It’s been done in Toyota’s other platforms, sure.
