^ that's exactly what i was going to point out.

its the higher boost that is making more power, and all the E85 is doing is alowing more boost to be run without detonation.

I think my GTR could make near that if it were able to hold 25psi boost, but it seems to peak at 25 then trail off to 20psi

Anyway's, will see what it does on the dyno this weekend

Are you running standard or aftermarket actuator / wastegate springs? Judging by Donnans HPI article, youd see some good results with a stiffer spring!

I've got 14psi actuators from memory? i remember when i had them fitted to the std motor the tuner had to just run wastegate tension because when they were plumbed in boost would hit 18psi.

i've got an Turbosmart E-Boost Street, so it should be able to control boost well enough. might just need some fiddling with the settings to control the wastegates better?

shouldn't i just be able to have the wastegates tightened to hold more boost?

i think they're adjustable, they have a threaded rod which looks like you can tighten of loosen to adjust when the wastegate cracks open.

yeh go speak to jason at mtq.

my external gate hold 20psi flat, put 25psi through it and it bleeds back to 20psi, fitting a stiffer spring will mean boost holds and it bosst will come on earlier too :)

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
