It will be interesting to see what gains the ITBs will give on an otherwise stock engine 🙂

 

we have arrived at 300 hp and was much too poor. after two runs we were at 340 hp. it is an automatic gearbox and it takes a lot of power

 

Do you have a reference before you installed the ITBs?

 

We've always had trouble dyno'ing the automatics. Usually we disconnect the kickdown cable, pull the kickdown switch at the gas pedal, and then run the car up through the gears manually to 3rd gear (not 4th) and rev to around 2000, start the dyno run, and then floor it. Had issues with running in "D" (4th) and the top speed of the dyno (248e dynojet). apparently it loses all the data on the run when the speed is over 200 (which it is on the 2.2 rear ratio AT).

Also, very cool color. Looks great. Hope you are able to squeeze out some more HP.

 

no the car was in bad shape when i bought it and the engine was not running

 

That seems very respectable for a 5.0, with only ITB's added.
Like you say, the automatic "absorbs" a bunch of power.

 

Dear Charles,
You may have noticed that a fellow Belgian enthusiast is making the exact same car. His name is Barry (at least, that is what he wants us to believe).

 

Ad, Charly is my "neighbour" ...

 

😀😀😀

 

Barry's 928 is on Webers carb, mine is on itb's and injection. A race for the most power 😀 Webers is for old people

 

old people ? okay, i'm old but at least i don't have to worry about ...."how many degrees before top dead center the two missing teeth are on the flywheel".......

 

Now this is going to be fun to watch! Two neigbours racing / rallying against each other in hot 928's.

 

How did you get the stock LH to work with individual throttle bodies? I assume you eliminated the MAF and replaced with a MAP sensor, then tuned with a Sharktuner?

 

Did I miss an earlier thread which describes what was done to this car?

If not, it would be helpful knowing what mods were made.

And I agree, 340 rwhp is not very good for ITBs knowing that Alex and John did 430/450 rwhp with their 5.0 manuals.
