Hey guys I think i posted this before but it had too many complicated information for you guys to look at. I've spent the past few months enjoying the car with the current setup and gathering my thoughts.
I have TLAO chips in my 1990 760 Turbo Wagon.
Using stock(ish) injectors at 15 lbs of boost
3 inch 960MAF.
19T Coldside, 15G Hotside
VX IPD Cam
No boost leaks w/ pressure test
straight piped 2.5 inch DP(its very quiet when having all the bends to the back of the car)
So basically, The car is quick but just not quick enough. Its like 85% of what i'd like for it to be amazing. Im almost there to what I will be satisfied with. It is very quick on cold days and slow on hot days. However, I don't expect the car to be fast on hot days. I just want it a little faster.
AFRs on the onset of boost(at WOT) I see 13s. Past 6 lbs of boost(by feathering the pedal) the AFRS drop down below 10. I have a gut feeling that it's around the 9s which means that there isn't any misfire but the car is not as fast as it can be. Any increase past current boost levels I hear pinging.
So what can I do to make it a tad faster? Unless I get someone to custom tune my car or have some sort of device to do it myself, I will be stuck with these AFRs .
I was under the impression that stock injectors w/ 3 inch MAFs make it richer at high boost?
Whereas If I have Bosch Green Giants w/ 3 inch MAF it will be better or worse? You guys told me on my previous threads that it will make it richer? However, Im questing the scaling of the injectors to the MAF. It won't make it leaner? What injectors would you suggest? Maybe slightly higher at 350cc or so? I think I'll be happy at 18-22 lbs of boost.
In the past, I put 650cc EVI deatschwerk injectors in there and it was Rich to the point of misfire.
Currently, I am daily driving a 2004 S60R w/ methynol at 25lbs of boost(I bought it used for 3k$~). It is faster but just doesn't feel as fun and have RWD torque like my rear wheel drive 1990 Wagon. Plus my 1990 Wagon is much more comfortable, doors sit lower, has an automatic transmission, a really powerful audio system, better turning angle due to not being AWD, and softer suspension. The S60R is super hard on bumps because the previous owner put sports shocks on it and it has a STAGE 2 CLUTCH! (which is almost a nightmare to drive!). I can kinda tell that Volvo had its golden years in the 1980s-1994s, the cars nowadays are just not as good as the previous ones(imo)
I want to make Betsy(90 Turbo Wagon) faster. Please help me. I've pressure tested the car like twice and there are no obvious boost leaks(Unless its in the cabin behind the dash or something). Im going to duck tape my CBV to be sure but I highly doubt it will help the rich AFRs much.
