I had no indication that the Walbro pump was anywhere near the limit - the VE table only rises 10% or so from 200kpa to 300kpa since I have a boost reference. Fuel pressure on the hero pass was 84-85psi.
Valves and headwork would be very beneficial at this power level. It won't make a big difference on torque, but it would probably have pushed this setup north of 500whp. One sick turbo if it does! Head work would cause a big drop in the boost required at the same HP? Any IAT drop is always nice at the track! Would allow a big jump in the pump gas tune as well I would think? Killer build Andrew!! |

Same exact mechanical setup that did 297/272 a couple of weeks ago on gas with the exception of the fuel pump (swapped DW300 for Walbro 455-E85).
Nice job Andrew. RE: T5 trans: it would handle anything you can throw at it in a car as light as a miata. But with the bolt-in BMW trans option, why would you go with a T5? |
The head is not ported in any way and has stock cams and still makes 10hp/psi?
Its extremely strong, in my opinion. The turbo must be extremely free flowing on the exhaust side. Dann |

Andrew, did you ever document your fuel system build? I am planning out my winter purchase and want to copy what you did (or maybe just buy it all from you?).
You kept it returnless correct? Did you put the e85 sensor in the engine bay or in the fuel filter location like the Flyin' Miata kit? Would you be able to talk me through it via email if not on MT.net? |
its all in his thread
|
Ok, looking now. I must have missed it. Edit: crap, I found it, and I saw it back when it was posted and have been trying to find it ever since. Sorry for mudding up your thread. Feel free to delete both posts.

Fuel system starts at post #331 here: https://www.miataturbo.net/build-thr...t-84579/page6/
Cliffs notes: DW300 or Walbro 450-E85 in the tank, 10awg milspec wired to bypass the OEM connector with bulkhead isolators, dedicated 30A relay wired straight to the battery. Gates $20/ft submersible E85 hose inside the tank, Earl's Vaporguard everywhere else. Fuelab 818 filter replaces the stock unit. Fuelab 535 regulator at the back of the car, OEM lines forward of the rear bulkhead, OEM fuel rail, ID1000s. I sell all of it. |

That's where I plan to get my fueling stuff. |

Carlos, hurry up and buy allofit to run allofit |
I am driving for a minute, when it's dry out anyway
|
I cannot emphasize how dangerous this car would be in the wet without the Racelogic gods preventing me from doing stupid things :rofl:
|
Seriously, even my car must be driven like an elderly person in wet conditions. Any gear, super dangerous.

The racelogic is no longer available, correct?
