Ba/f With Fg Turbo Plenum

Why can't we only quote part of the previous posters quote?

Just a side note. After my tune many made the assumption that my handy work was a waste of time. The restriction in my car as it sits, is the outlet of the monza cooler, but we were never going to see if my handy work would resulted in a horsepower gain, due to not running at, or beyond the power levels the factory platform is known to achieve. And the fact that the intercooler is the restiction at this point.

Easy, give your plenum to Big Al as he is at the limit of the stock one.

Impellor, did you change injectors when your car was tuned?

Have you backed this up at the pump or just on the

Regardless of the so called experts. The stock plenum can be improved upon. The biggest restriction is in the opening, which is smaller than the T/B outlet. My advice is to smooth the T/B outlet to the same size as the inlet. Then get stuck into the plenum. Firstly, rip a whole heap out of the opening (to match the T/B), and remove a sh*t load out of the curved inlet area, to provide for more flow into 1 and 6. Grind 4-5 mill off the lower casting area, where it flows into the inlet runners. Grind the tumbler openings and smooth. Finally smooth the internals of the tumblers, and plenum.

But can anyone explain why I am geting 5.2 litres to the 100km's on flat road in top gear doing 100kph (as opposed to 7.2 pre-tune, always run BP Ultimate). The only thing that I can come up with is efficiency. OK what I have isn't going to win dyno comps, that we all know. But what I do have is a setup that is proving to be ultra efficient at cruising speeds. Which I believe the fuel consumption figures are proving, as they really are the only way to measure an efficiency improvement at this point. Now obviously the tune plays a role through enhanced timing, but I don't believe it is the answer to all the improvement.

Is this at the pump or the dash display?

As I've stated before I am quite happy to meet Impellor at RDP and pay for the dyno runs to see what sort of improvements if any have been made. Wouldn't think it would take much longer to swap plenums as it does for him to write his long winded posts.

I asked you a question a few posts back and am curious to know in which way you found the aftermarket plenum better.

.

1) Power;

2) Visual appeal;

3) Economy; and

4) Throttle response.

Thanks Toads

Knew that was coming. Yes I filled the car and did 86km's making sure never to boost it, or get even close, as the fuel gauge only goes to 99.9 l/100km. So once boosting up the fuel figure isn't accurate. But the instantaneous has always been good. But I needed to be sure. So anyway average fuel usage was at 8.8. Went back and filled it back up cost $12.05 @ $1.589, which was 7.54 litres . that's is actually 8.82 l/100kms. Injectors 60lb Deka's.

I like the FG one as it looks factory, can support 600+rwkw, shortens intake tract and was half the price of Plazmaman etc

How much f*cking around did you have to go through though? I personally like it and would do it if it was a simple changeover..

I tell you what I'll do. I have a plenum here that I could do for you. It would actually be improved on my first attempt. We can go down to see Lee and try it. Now if it doesn't work you can have it . But if it does, and gives you 10% more power, as long as the supporting mods are capable. How much would you be prepared to pay for it?

Cheers
