24/07/14 Toyotec's 315PS WOLF R. What's next? See Pg10?

You might be surprised to know...most of it was developed outside my house!!

 

Being that this is your current setup I was curious if you would continue to find the limit of this compression drop method.

 

Is this to add to the theory that stacked gaskets isn't the right way?

 

Ah got ya!

Once I am happy with the vehicle's grip on this level engine and it achieves a pending objective, another will be built to suit any requirements or new objectives. The new challenges tend dictact the hardware components chosen.
Let's see what happens when that chapter arrives

 

It's not a theory. It seems on VW engines you can go so far with the method, moreso than some other vehicles, but low comp pistons is always a better idea.

If Eddie is going to use a different build to achieve a higher output then we can look at the possibility of 315PS or something in that neighbourhood is the limit of stacked gaskets before something goes wrong.

Eddie, by looking at a new build for the next possible power goal, are you saying the current build method has reached it's limit or that you're simply going to trial the limits of another build?

 

Answered in the above post already.

This was a DIY budget build involving significants amounts of research and hands on. It has more than exceeded the tasks set for it as a project.
The next engine stage builds on this experience but goes to another level.
Peharps you need to be taken out in it to separate talk from Torque!

 

I think you'll find its not necessarily to do with gaskets. And we aren't talking about other vehicles here.
For this level of output, its proven that this method is suitable and reliable over spending 5-600 on Low comp pistons. But then as the required ouput level goes up, then you have to worry about rods too.

 

+ you would not buy pistons 'just' to achieve 300PS. Such a build would be for someone who is more serious and would include a set of rods while the short engine is in pieces + the rest.

 

tshirt2k, I know we're not talking about other cars, I'm simply going on the awareness of when people have used the multi gasket method, among other head spacer methods, to drop compression over replacing rods and pistons it has had undesired consequences.

Of course this could of been caused by over zealously turning up the boost and popping the engine. My comparison to other engines was that these VW motors seem to respond well to this method of de-compression for some reason up to a certain threshold. I'm not denying that it works, it appears to have limits of course but you're already aware of that.

It appears my previous conclusion that it's simply a "cowboy shortcut" was mistaken, it seems to be a good way of working up to a certain level, be it in the 300PS region or not. It's come to a point where I'm tempted myself and am wondering if I could make 200-230PS on my 2.0 8v using this method (the engine will eventually be ditched for a better one so I don't see why not.)

Perhaps we should start a new discussion about this, I'm keen to see what people's results have been overall and what limitations have been found.

I'm more than happy to go for a ride in the Wolf R. I'm not doubting that you researched the build extensively, from speaking with you in the past I doubt you went into this lightly and am impressed with the figures.

 

Toyo - this has been quiet for over a year...........
Pull your finger out

 

I don`t believe Eddie hasn`t touched this for a year !

 

I can't believe he hasn't touched it for five minutes!

 

Did you ever change the manifold from the one in the thread ?

 

Car was last tested here and I stated what I plan to do with it.

The car has the same components as in the last dyno day.
Off car, work is ongoing for the next stage, but forms a queue with my other priorities.

Cheers for the interest though

 

When you engineer a vehicle properly there is no need to 'touch' it frequently.

 

You know I`m interested in your many projects

I just wondered if you`d changed the exhaust manifold as you felt that was hindering the setup.

Just because we don`t NEED to `touch` our vehicles, doesn`t mean we can`t leave them alone without tinkering... lol

 

The vehicle is left alone for the time being as is just a spare road car for now.
Look at the dyno link for the last test the car as subjected to. That would give you a flavour of where I believe any current problems lie and hints to the next steps.

 

Well Toyo, one year on, any movement on the WOLF R?

 

Yes there is lots going on behind the scenes with all my fleet. I just have been lagging behind with updates. I drove the WOLF R on Monday and about to send it in for some detailing.
