Yes I've seen 30% as a safe top end number before an extra fuel pump and flash.
However they say monitor trims on a JB4 log to see if you can push it a bit more. Don't want to over stress the standard fuel pump too much though. |

Okay added 3L of ethanol to the tank which had around 15L of momentum left in it...added another 15L of Shell V power just after to make sure it mixed up! So if we assume that both fuels have 5% ethanol content I should now be running on E15! I will do a couple of WOT's tomorrow (weather depending) and then up the ethanol to E20-25 if all goes well. Wish me luck

Meanwhile the damp, salt and dirt on the roads here is making traction difficult.
I was getting understeer this morning and oversteer while joining a junction. Was just trying to nip ahead of traffic approaching at speed and ended up snaking around looking stupid. Warning, contains a bit of language. |

I am exactly the same. Just bought a set of Michelin PSS to hopefully help cure it. Still wearing them in though. Interesting note on the Momentum 99, I used to use it in the e46 330 and found V Power made it run better. Might give it another try and see how it goes. |

Hi guys, gave it a blast last night and got a misfire on cylinder 3, i can only presume this was down to the ethanol...perhaps the quality isn't up to scratch. I have also upgraded the charge pipe and added a tial bov since my last log so may not be comparing apples and apples as per Windymissles query. So back to the start...filled up the tank v-power, changed out plugs (already had purchased ngk 5992) and just to be sure changed the coil pack on 3 (have 3 spares at hand) so will do some runs tomorrow which will give a good base line to work from. May also bite the bullet and purchase sunoco e85 then i can be sure of the quality. Attempted a couple of runs today but too greasy! Can't attach the csv file on the forum!

I have read somewhere that it can take a while for the jb4 to adapt. Your story sounds familiar to another's I was reading. If I remember, the misfires cleared up after a couple of pulls and the tuning had adapted for the ignition advance.

I've been using bioethanol for use in fires for over a year without problem. I run upto 15L per full tank of tesco 99. Here's some details from previous threads;

I had to give map 5 a go today and I resorted to 4th gear. That worked for me but you need a good stretch. Momentum is happy on 15 to 16 psi. |

Gents,
Unfortunately conditions were not ideal...again! Did a few logs but traction control kept coming on through the runs...this brief run was with the DTC pressed once...I'm usually seeing around the 18psi with Shell / Momentum but as you can see didn't get WOT until 4K rpm ( what a chicken shi*t)!! So hopefully next weekend we can try again! Cheers Russ

Russ is running modded turbos and meth. 18 psi is about where it should be.
I have had 20+ with meth on standard turbos. I'm not sure if there is any room for improvement with E30+ on standard turbos. It's a good experiment though, and if there is, it will be good to know for the summer. It's going to take a half day of pulls with various grades of fuels in good conditions to clarify. - Are you running with the meth kit in Map 3? Or just in map 5, Russ? WM |

I must look what are the upper limits of the Vargas. WM, don't you get nervous reaching 20 psi on stock turbos? I wonder how many rpm they are doing at that boost versus the 7 psi? |

Hi Guys,
I run Map 3 daily....was actually thinking whilst doing the test to change to map 5? What do you think? Got the Vargas turbos late November...for 2 reasons the main one being wastegate rattle (driving me crazy) and I was also seeing a little smoke (oil seal on turbo) on decel...although there was no power loss..just sounded like I had a tin can under the bonnet WM: Did you up the additive to 70-75 to get 20+ psi? I'm at 50 additive at the moment and boosting .5 to 1 psi higher than the meth additive boost curve supplied by Terry http://www.n54tech.com/forums/showthread.php?t=22272 I'm putting the additional boost down to the stage 1's. Initially trims were looking high and meth not working properly..but I think that was down to the BMS elbow I was using. The meth nozzle was just too far back in the elbow so I don't think it was spraying correctly...now meth nozzle is installed in the VRSF charge pipe which went in a couple of weeks ago....this last run trims are looking much better! I will continue to minitor though... Cheers Russ

I'm not too worried about the extra work the turbos are doing. They are both new. I monitor and log regularly to keep on top of things. WM |

I hope I can get water/meth myself later this year. I also like the cleaning effect myself. Hoping it prevents the built up of carbon deposits and maybe even reverses them? |

Is there much difference between the Vargas stage 1's and stage 2's? I'm thinking about upgrading from my Hybrids and adding Meth now.
