Are those stock IGN coils ?

 

The facility where I work was authorized to tune V Pro and I actually had an Evo harness sitting around so I figured I would give it a try

Any stand alone ecu will produce the same results as any other, after all its just injector on time and ignition.

The main reason to experiment with this was becuase I don't want to do the R & D on a customer's car. Its always interesting to learn new tuning platforms.

V Pro is certainly a wonderful box.. What we like most about it is the OBD II emissions compliance.

I am still learning.

Next we are going to install it on George's '08 STI and see how it works on Subarus.

For the price of the Buschur Stage III head - being fully loaded with Super Tech valves, spings, retainers, valve job and ported for approx $1650 (I believe) you can not beat the value - anywhere

I was approached to do some cylinder head testing and being the open minded guy I am I wanted to see if the head maker's power calims were accurate or not

This is why I am taking the time to do a test

 

I have no expectations

This is part of conducting a test - having an open mind and seeing where the testing takes you rather than making assumptions based on opinions which are not supported by facts

 

I have not tuned any start up, partial load or closed loop matters as of yet and it needs more work

It should be noted that the most I could make previously with the AEM was 800 and now I am at 823 but that includes a variation in climatic conditions which may explain the difference

From what I have seen in the past the V Pro runs like a stock car with the right tune up

Also the Hydra is similar in a stock like feel

 

Yes

Stock with HKS Twin Power ignition

I have been to 56 psi of boost and 1060 whp on the stock coils

Al

 

Yes and to my suprize it has a KNOCK control device - although I did not install it in my car we will be using it on the '08 STI - its called the knock amp a/f display - really trick stuff

Al

 

Did you have a BR ported head before? If so, how much power was it putting out before you went back to a stock one for testing purposes.

Will you keep the VPRO in the long run or does it depend on how well it performrs?

 

I am pleased that you have detected the sarcastic nature of my theme

Recently, we have been hearing of a lot of armn chair experts who have never ddriven, built or tuned any fast cars who have been pontificating on how they think a fast car should be designed. When I asked these individuals to back up their theories with some sort of evidence or factual basis to support the claims they had no experience or real world condition to support the opinion.

The point here is to show people that having a understanding of what works and what does not work often requires going through the process to seek the truth.

I have heard claims of 90 whp being "picked up" from ported heads. My goal is to test some heads and see what happens and try and learn something in the process.

My old assumptions when I started tuning turbo cars in 2001 were based upon what I heard and read in magazines and internet forums. As time has gone on, I have discarded a lot of that data and learned a lot of things about working with stock parts to get good results.

I am very interested to begin the head swap but first I had to take the Evo out to shakje off some cobb webs on the way to McDonalds this afternoon

Al

 

I had several Buschur heads

I broke mine last year right before the shootout and there was no time to get another

(It broke becuase one exhuast valve spring failed and the heat damaged the port)

Thanks to David he hooked me up with a 100% stock head with springs and I was really suprized to see that my car actually ran very well with that set up.

That and the stock intake manifold testing and results of the past year really woke up my thought process

I have a brand new Buschur Stage II head here which I may also test if I have enough energy - I am also trying to get my STI ready for the May Buschur Sport Compact race

I will probably go back to the AEM on my own car as I was always sponsored by AEM Electronics and I have had great results with them. We do intend to test out the V Pro on more platforms and we are going to get it in out '08 STI very soon.

Al

 

i would be willing to pay for your next trip to mc'd's and even super size it if you would also put the Bushur head on too...I wanna see the curve.

We are doing a similar test soon on Sean Ivey's beast. Has a stock head on it.
From my experience with your size turbo, picking up only 50whp over stock would be VERY easy. 70-100whp with a good head is more like it. But..I could be wrong.

 

Dave,

There's a point (where I believe Al is at right now) that it won't matter what other mods he throws at the car, he's at the limit of the turbo combination.

Now, he might be able to make his current power at a few PSI less with a better head. I don't see him picking up much/if any peak power.

This test might have more merit at say 30psi when the turbo isn't at maximum output.

 

Well given this idea, perhaps race fuel / max boost is a terrible idea for this test. Because on a low octane fuel, making equal power at less boost will yield big gains in max power.
