So whose using a rising-rate fuel pump regulator?, Not turbos; or using a cold start valve as a 5th injector? |

Who has played with a rising-rate regulator or adding a switch to a cold start valve to be used as a 5th injector to get a little extra pony power?
Here's one... MicroDynamics RisingRate Regulators are designed for use with all types of fuel injection systems. Added to standard systems they increase the mixture range for high performance or provide "boost or load enrichment" on both turbo and naturally aspirated engines. Rising-Rate will also give more fuel at the top end without going over-rich lower down the rev/power range. A MicroDynamics RisingRate Regulator is often the only form of fuel enrichment required for many retrofit turbo conversions and is usually the easiest way to obtain increased fuelling on production injected race vehicles. Here's one by Bell Engineering $179 Here is an interesting article how to make your own rising-rate pressure regulator from a stock 914 regulator Attached image(s) |

1450F Uhhhhh.... No wonder the headers were white.... I B surprised the engine didn't take a shit on you. Is this the MS brained engine? Even better... Do you have pics and a build sheet for induction, spark, turbo, brain, complete fuel system setup, etc.... Cause that thang needs a fixin................... This way we can hijack the entire thread... Just like the good old days...... C |

This way we can hijack the entire thread... Just like the good old days...... C Yep - that's the one. It does run MS-II with an LS-1 wideband O2 sensor. It has a raising rate fuel pressure regulator sensing manifold pressure. However, I think we are running too lean under boost. I need to get the laptop hooked up again to read the wideband data while under boost... Last time we had to sort out timing since we got some pinging under boost. The MS-II software is sort of buggy. Often doesn't remember changes to the 12x12 tables and reverts back to an older setting. This makes tuning cumbersome but it needs more work.... |
