Yes JB and Chips :kissmy:

I had them fitted last thursday, they will take me to my target of 300rwkw, just got to get this valve flutter fixed first :gooff:

George when I am finally happy with the design I will then make some inquiries about emission legalities. Don't want them coppers hassling everyone who uses them :siihp:

The Shaker is certainly an attention grabber. :w00t2::w00t2:

Hi Pretzel, :kissmy:

Be patiant and keep your hand on your wallet just a little longer as I want to make sure everything performs as it should before I see people parting with their hard earned.

Dyno results didn't show great improvements a this stage, I was'nt really expecting any first up as I new that I could design it better. Lets just say that it did'nt hurt. I have now sourced the parts that I need and I have made some major improvements to the intake from the shaker to the turbo. I have shortened it even more it now travells about 200 mm and is a lot more free flowing, which should make the car even more responsive. I would be expecting to see some HP gains this time. I will post new pics when completed.

There was however 2 big improvements, that I really was'nt thinking about as I was more interested in the horsepower gains.

1st thing that is apparent is how much cooler the engine runs whilst travelling along the highway, the temp needle sits just above the 1/4 mark.

2nd and probably the most important considering the price of fuel was the drop in lt/100km. I used to get 13.5 lt/100km I then installed the Exede, which dropped it back to 9.5lt/100km. On the way to Melbourne last thursday with the shaker fitted it dropped back to 7.2lt/100km with cruise control on, a lot of the time it even went into the 6lt/100km.

As you can see by these figures the shaker really comes into it's own out on the open road more so than when the car is sitting still on a dyno.

At the time of tuning, the car started with 224rwkw and by the end of the session it was producing 256 rwkw at 8psi. We could'nt run anymore boost until I fit the new valve springs because of valve flutter. Once this is fixed we should be able to pull up to 300rwkw. I would like to dyno a stock car with the shaker fitted I would expect to see some good improvement.

As for costs still have to sit down and work it out. The new changes should lower costs even more. I'll keep you informed.

Hope this anwsers some of your questions. keep them coming and I'll do my best to anwser them

I think the reason your lt/100km has improved is because you have changed your injectors an are getting a false reading from the trip computer...I went to QLD last week and got 7.3lt/100km on the computer when it was only really getting 11lt/100km

Hi guy's

I'm only reporting what I see. As this is the only trip that I have had the opportunity to take the Beast on It is early days. When I get the car back I'll be doing some more research and post real world driving figures.

The mileage of 7.2lt/100km was before the new injectors where installed. After they were installed on the way home the trip computer was showing 9.2lt/100km

Before thew Exede was installed I was lucky to get 560km per tank. After the Exede milage improved to 700km per tank. Your wallet does'nt lie. the 9.5lt/100km used to give me 700km per tank which also included some spirited driving as one doeswhen you own a T :crybaby: , so if I am back to where I was before the larger injectors and have increased Kw as well something must be helping, so my guess is that it's the shaker.

Macka,

Thanks for the response, another couple of questions I have are how are you handling the water (Rain) both into the intake, and into the engine bay around the shaker ? I have had Shakers on V8 falcons in the past, and know how they handle it there, just wondering what you're doing to allow for it ?

And the other question relates to the cooler to Throttle body piping, what if anything are you doing there ? do you retain the crossover pipe on the top of the rocker cover or remove it ? (I am hoping you remove it as it seems very restrictive)
