Judging by his injector size in his signature, I don't think he's on E85. I do see WI, however, how the hell are you not getting detonation?
|
I have sigs disabled FTL
That makes it even more insane then: all that boost/timing on pump gas+w/i? You have balls lol |
WI makes that timing graph make sense. I was like holy fuck shit at first though.
Brain those pistons are only 9:1. Not super low comp. |
8.7:1 is super low, 9:1 is low. Got it.
thanks for the clarification. |

I did a lot of adjusting on my boost controller but usually between 17-19psi. Lots of timing. http://i255.photobucket.com/albums/h...565/ignadv.jpg Stock fuel pressure, 550cc injectors. I recommend you pull 3* or so from 128kpa+ if you ever plan to put the car on the track. That spark table can work on the street, but considering time where I'm running the car from 100-158mph every lap, pulling some spark angle makes sense for reliability. I keep telling myself to install the EGT gauge and get better data, but that requires drilling into the AF manifold and I don't have the heart to do that. I'll post my spark table later, but this dyno sheet shows the progression to MBT while tuning at low boost for NASATT classing. I added 2* on each pull and you can clearly see that red is the greatest output, green is advanced beyond MBT, and blue is where I started and where I left it. I'm not sure how much extra heat that 3* retard from MBT puts in the exhaust, but I still see <190*f radiator inlet temps.

thanks for the clarification. I'll be doing a piston swap to 5.1:1 soon so I can run >100*

Holy shit:eek5:
That is a ton of timing in boost. out of boost though most of us run ~40 or so. could probably bump that up. Thanx for posting the spark map. I'm always dying to see other e85 cars spark maps

ahem WI has alil something to do with his succes as well.

However, I run my spark angle a bit lower today after I started letting the dyno pull-down the motor to get a good, realistic track-like duty cycle going, while using Jeff C's det cans. I wouldn't say I heard detonation, but there is a change in the combustion sound, slightly off-rhythm when doing this procedure. That sound made me yank a couple degrees and the syncopation-rhythm went away.

Ah shit, disregard everything I just posted...maybe I'll leave it for the good of the people. It's even lower if he's on an early 1.8 bottom end and a 99 head. |

You wouldn't happen to know your launch control settings would you? No matter what I do mine tends to want to hesitate to launch rpm and never seems consistent.

245whp, 11psi, track safe in my opinion:
http://i55.tinypic.com/23k5rc.jpg I had to drop to 9psi and lower spark to hit 210whp for TTB bullshit classing. |

http://www.atpturbo.com/mm5/merchant...egory_Code=GRT Thats the one i bought. Attachment 190708 And for some reason, i cant help myself but to post a picture of this baby. This is my favorite part of the car. Attachment 190709

You never answered our question about this statement.
There's a rumor in town that the 949 clutch overheats on long drives for some reason, can you attest to this? I hope this is the case, it will save me some money. I guess you also agree that this clutch changes the game and makes you smile every time you drive it? I'm always giddy when I hop in John's car and I'd really like to get one in my car. I have a standard weight clutch assembly right now and I'd really like to downshift faster, especially with the tight ratios; I've been skipping gears on every downshift. |

I thought you sold that clutch.
