Toyota 3sge Revision 3 ACIS Spacer Group Buy

[HurleyRacing]

Had some interest in this from a few people so thought I would see if there was enough interest to start a group buy as a first batch.

Our 25 mm CNC machined spacer made from aircraft grade aluminium, gold anodised. Comes complete with new bolts and, genuine toyota ACIS gasket.

Here's a pic of one fitted to our engine in our race car.



Picture without cover on can also be seen on our website

Does it come with the decal

[HurleyRacing]

Well you would use your own top cover but yes I can provide the Gold Decals for it

[Ryan6926]

I don't need one myself as I already have one but for anyone interested, these really are great bits of kit

Ah I want one what's the benifits of it? I was looking at the kamikaze ones ages ago but nobody really knew the benifits

The main benefit is that it add's more torque which is handy on the Rev 3. I had one and noticed an increase from 2k rpm where it felt noticeably quicker,

In addition upon putting the car on a dyno I also found my car was still making power at the rev limiter as opposed to another GT which was standard which peaked around 7k

[HurleyRacing]

yep, what ryan said.

taken from our website.

''The HRE ACIS Volume Plate increases torque at acis change over by changing the acoustic signal and providing a larger chamber of air to draw upon, which in turn increases power, typical gains 3-7 bhp on an engine in good Condition. Works especially well on engines running fast road cams with a greater overlap than standard''

[Davsurfa]

Can I just ask how come you make them at 25mm? I'm just curious to height choice

[HurleyRacing]

Sure...two reasons really. its what we felt was right for the engine,( using experience from other similar engines) and the fact that the majority of people will have standard cams or fast road cams.

Also it's a stock material size. Therefore eliminating wastage and keeping cost down. Can make them any size you like however cost will vary.

[synXero]

Does this mod work on most engines?

There must be some kind of trade off between the increased air and thus power and torque, and something else? Why don't cars come with enlarged plenums from the factory?

Would it work as well/better/worse on a larger engine? An 8 cylinder?

[HurleyRacing]

It depends on what the engines acis type system/ plenum are like and how well they breathe to start with.

With any modification to any engine there is nearly always a trade off, whether it be induction noise, fuel economy , engine bay/ bonnet restrictions, cost to the manufacturer etc. These are all reasons as to why manufacturers do the things they do. The same question could be asked about free flowing exhaust manifolds etc

As to a v8 again it depends on the engine. All engines are effectively air pumps, so to increase power you have to have better breathing, more air or turn it faster , more revs.

We now have two down so far for the group buy.

[RikH77]

Work on a rev5, stock engine. Gasket wise do you supply one for top and bottom of spacer?

[HurleyRacing]

yep works as same chamber as rev 3, supplied is a single gasket. if your existing one needs changing we can supply another at cost however not included in the kit

[tezmc]

I'd be interested if it gives the same gains on a Rev5. What could I expect with a standard cam? Also, how much would an additional gasket be?

Cheers

[Donato]

I have just fitted a ACIS spacer / power deck spacer. Made a bit of difference low - mid in torque. Slight bhp gain i think. But definitely noticeable and i'd recommend buying one!

[HurleyRacing]

I would expect the same gains from rev 5, off the top of my head don't know exactly how much the gasket is, I have it somewhere and will drop you a PM when I'm back in the office, away racing this weekend now so won't be til Monday / Tues

[HurleyRacing]

Acis Gaskets are about a tenner from Mr T i believe.

[HurleyRacing]

We have one more down for the group buy - One more person and we will be down to the next discount level.
