Default 240 B230f+t Dyno result

so i turboed my 87 240 unopened b230f 80k miles with a 19t its running 7.5 psi it has 118 whp in second gear and the dynograph dips at 4.5k to 5k but then pull to 6k like nothing happend and is so Rich that it wont go higher than 3.7k rpm in 3rd then it gets so rich they stopped the dyno run so it has orange top injectors 90+ manifold and the do88 bigpack intercooler its lh2.2 with ezk ignition. so how can i get it to run leaner? lambda is at .7 from 3.5k to 6k

Check O2 sensor, FPR for leakage. If those are good, you can lean out the AMM by taking out the tamper plug and turning the adjuster to the left from what I remember for leaner.

Adding more boost isn't a solution if it is running super rich. You need to figure out why it is running rich.

Do you have access to a fuel pressure test kit to see what it is doing at idle and if fuel pressure goes up under boost?

Do you have all the correct LH 2.2 pieces such as AMM (007) and are there no boost leaks between the AMM and the intake?

Have you compared the look/color of the spark plugs to a chart to see if they have any clues?

I assume the orange tops are similar flow rate to the stock turbo green injectors?

Also check the coolant sensor, best place to check is at the ecu, that way you can make sure your wiring is good too.

14 psi can be safe as long as your car is setup and tuned correctly.

Have a ****ed up tune or boost leaks or flaky other components.

BAH BYE

I wouldn't feel bad about shoving 16 or 17psi through a skinny rod motor if it was running right. Probably still wouldn't beat a GTI though.

Only way you're going to beat that GTI is if your pour sugar in his gas tank...

0-100km/h for a stock Golf 7 GTI is 6,4 seconds (according to my Google skills). Very good response with the DSG etc, don't underestimate it.

If your 240 isn't overly heavy and have some basic mods to your +T it should get similar times to 100 km/h. Think a proper exhaust and making sure it just runs as it should. The DO88 intercooler is a nice touch and helps for sure.

The main bottleneck is the stock turbo. Luckily you can swap FWD mitsu turbo's that look completely stock (for TüV) if you want, though you can get much better turbo's for the same $ but they need more mods to fot them. My 245 +T with a T3 at 7-8PSI is below 6 seconds 0-100kmh and it is a very very basic setup, nothing special and many things that can be improved. Close to 100K on the +T and it runs like the first day, don't worry too much about the engine.
