If your pump is standard you will have to make somewhat of a compromise when tuning . Your pump hasn’t got enough adjustment in it to fuel ideally at low rpm and match the capability of the turbo as well . A “built” pump with more aggressive delivery, more overall capability and a revised...
Copy, how do the timed runs compare between setups ? Not really a fair comparison but interesting to know still.
With timing I was referring to the timing advance mechanism in the pump, was wondering if you had it mapped to complement the turbo and higher rpm power band .
I do too . Something i picked up from My dad. Even though my driving isn’t even close to a controlled environment I can get a Good idea of average economy.
The dyno charts, are they the same car, did you change turbos and diff ratios? The extra load from 3.7’s over 4.1’s will make the pump behave a little differently
I am surprised fuel efficiency isn’t sacrificed with the high rpm turbo .
What are you doing with injection timing advance when...
As a pump wears it will loose case pressure and thus timing advance on the pump .
Injector springs wear/loose tension and take Less pressure to open so advance timing .
How a pump is built greatly effects where static timing is set . Once u spend time playing with them it will become clear...
@Wildnlost if you don’t want to read white paper studies on emp & drive pressure google Banks performance they have some videos that touch lightly on the subject . Eclipse turbo systems have some basic info on their website also .
Via a tapped hole in the manifold, like in the above photo . Once removed it can be blocked with a bung. Data logging equipment can be easily plugged into the transducer and un plugged from it .
I use a very similar setup that I transfer from vehicle to vehicle. Couple of coils of copper pipe with a transducer plugged in one end . The transducer is mostly plastic and I’ve never melted one . Nice manifold by the way kiwi !
Had a few beers so this maybe a bit long winded.
It’s becoming common practice with some performance turbos to run hi tension Waste gate springs and mechanisms to limit gate travel . You see big boost (Extremely high shaft speed) and a boost gauge that follows throttle position. Looks cool but...
Short answer, I’ve not put enough km’s on one to personally recommend them . I don’t recommend things I haven’t thoroughly tested myself. But from ones I’ve seen others fit, run them within their design limits and they’ll have a decent life expectancy.
Like anything, there are the odd lemons...
I’ve tuned a few mamba setups and used kinugawa parts while experimenting. There are small differences between them and the genuine components they’re modeled off, not always noticeable by eye. It’s not uncommon to find small casting imperfections in the housings, which can usually be...
