Left it at factory setting and went for a drive. At first the car was popping and farting and over fuelling . After a couple of miles it settled down and the car started to feel a bit smoother but like it was now under fuelling.
I increased the max pressure by turning the adjuster half a turn and went for another spin. Again after a couple of miles the car started to feel very good.
Pulling away from standstill is great !!!! That annoying flat spot is gone and the car feels very smooth all the way through the rev range. The low to mid range seems to have benefitted most, but the high end doesn't seem as gutless either.
The car has stopped it's burbling and rumbling on over-run but I occasionally get a nice muted pop when I change gear at above 6000rpm.
Overall it's made an improvement. Dunno if I'd reccomend one if your car is running fine, but mine wasn't and so it's worked for me. The really strong stinky smell I had at tickover when hot has also reduced quite a bit.
Just have to wait and see what fuel consumption is like
Well just as an update, I now have the valve adjusted one full turn from factory setting. The car has really come alive. I had it one and a quarter turns, but this was too much. The car was a bit unsteady at idle, sounded good but was popping and burbling a bit much.
I'll keep you all posted................
Dunno as my car wasn't running too well, one of the problems probably being the fuel pressure regulator.
I'm sure it'd make a difference, but maybe not as much as I noticed on my car.
Don't expect it to knock seconds of the 0-60 time, it just makes the car feel smoother and a bit more eager to rev.
Well I'm thinking of one for the 1.7 16v Boxer and 8v Twinspark.
More so the boxer, to try and get rid of a hesitation at lower rev's and smooth out power delivery.
Seems there's nothing till 3500rpm, then everything goes warp speed. It's not too much of a problem as the 146 is the Father's transport and get's an easy life, still I'd like to do a few things once he goes away and the car get's it's trip to the bodyshop
Tried to do mine yesterday, which reminds me about a post i must post.
The suspense is killing me...
I washed my car last week and noticed two things.
1) It's at least 6 months since her last polish ( I Know ) and water is still beading, that's pretty impressive.
2) Some fooker has scratched the side panel which I've just had resprayed. They've somehow managed to catch the underside of the body crease. Anyway, luckily it hasn't actually scratched away any paint, just left some white rubbery stuff behind. I've got most of it off, but it's very stubborn, reckon it'll go totally next time I polish her.
Ieeee beeeeee playin' again
The valve is now set a half turn from factory. It seems to take a while to settle properly. On my drive to work this morning, the car was rumbling and on overrun. I can't afford to use that amount of fuel.
The car still pulls like a train above 4500rpm though, which is something the car hasn't done for as long as I can remember (if it ever did it at all).
At a rough estimate, the car is going from 80-100mph in 4th in about 20 seconds. The car did use to struggle to reach 100mph in 4th before.
Are you turning the screw in or out marlon ? i have one of these and it did give my car more pull in th emid range... but these days ive got a fault somewhere with either fueling or ignition, missing etc, and the car performs totally different each day... starting to wonder whether i need to get a new regulator now
I did think about that, but there'll be a point where it won't make a difference or actually harm the performance.
Most power is produced with a perfectly clean burn (as close to pinking as you can get), so overfueling is only gonna help my wallet get lighter
It would sound good though popping at the end of the straight and getting 6 foot flames !!!!!!
Given my regulator 1.5 turns clockwise (in) this week so far... a lot more poke all of a sudden, better throttle response but i still getting part throttle pinking... which is odd given a motronic ECU, maybe its the squadra chip doing its thing tho
I'd be careful about how you have it set,my mate had one on his 220 coupe turbo, i don't know what setting it was on but he managed to melt one of his pistons.the boost valve might not have had anything to do with this, but it seems strange that this only happened a couple days after fitting it when the engine was running completely fine before hand
