You're on corn and have kr? How? I have NEVER reached kr before MBT. From m62's to a 500whp s256.

 

Its not that hard... where do you live at though?

 

Indiana. On the 500 lsj mbt was around 24* on the top end.

 

Hey. Umm.... Bump.

 

so whats the deal (phone reset and I lost my numbers, gotta hit me up again)

 

Dammit Andrew....

 

Sorry man haha Im getting the bug again! Miss my car

 

Well since the thread is still current and I don't feel like a necro for going back to Alan's post lol, I have hit KR on my car on E85. On 23 lbs making ~520whp I can run up to about 24* before seeing KR, and on 30-32 lbs at ~600whp anything more than 19* up top is hit or miss with .4* of KR. 9.5:1 2.1L effectively 9.7:1 I guess.

 

I also have KR on my LE5. I *think* it might be false but not sure.

Any way to tell?

 

This just street tuning? Be interesting to see if you're passing mbt. On jons bone stock engine with the 256 at 28 psi MBT was at 22* up top.
Burst/anticipated kr will start high and taper, real kr (as far as the sensor is concerned) will climb. This is with standard settings.
As for false KR from an exh or suspension rattle, that will usually be random or at least vary where it occurs. If it's the same place every time it's probably real. However, I find it hard to believe you're getting KR at your power level unless you're way past MBT.

 

On the dyno I was seeing KR before reaching MBT it seemed like. Even after I had it where I wanted it, I pulled a couple degrees to make sure my gains on the way up were being reversed and indeed I was losing power. I didn't play much on the lower boost, mostly at 25-27 lbs is where the testing was done. As it sits now I am running 22* up top on 22 lbs, about 20* on 27 lbs, and 19* on 30. Just went out on the street and played around yesterday on 22 up to 30 and it seems like I have the tune ironed out for every boost level Just needs a tad more fuel up top on high boost with this cool weather, but I decided to go dirtbiking instead of doing more pulls lol.

 

On a side note, how do those 888's do in 2nd when it's normal temps, like 70ish?


We can ***** this thread all we want, Andrew won't be back on for at least another month

 

They do pretty well. If its nice and hot out like 85-90 it will hook in 2nd on a really nice road on like 22 lbs which is right near 500whp, and even on 30lbs if I pedal it a little bit it will spin, but its not a waste, it still pulls very hard while fighting for traction, its like spinning on slicks, lots of forward motion going on. On high boost in 3rd from like 70 it will try to break loose a little then catch, but if you do a small rolling burnout before you get it on it they stay planted. And going from 2nd to 3rd even on 30 lbs and somewhat chilly weather it will hook as soon as you hit 3rd. They seem to heat up quick when you spin 2nd and then just eat in 3rd. Even yesterday, it was 55-60 out and the pavement was cold from being about 35 the night before and I was out doing pulls. Anything above 25 lbs would spin just a little bit, enough to mess up my logs in 3rd, so I did a rolling 2nd gear burnout on the ebrake quick and then it held 29 lbs in 3rd I am more than happy with them to say the least.

 

Hmm. That is good news. I imagine that's what I'll be switching to when my 555r's are done. Really want something that can effectively pull double duty for corners and roll racing.

I turned mine up to 22 today. Woah.

 

You'll be amazed at how well the R888's can compete with the 555R's in straightline traction, and around corners is night and day difference. I will replace these with more R888's when they are done

 

Eww an auto :C

 

eww somone who wants to stay slow and broken

 

It's getting deep around here haha Might need the old hip waders.

Geesh all you folk and your fast cars. What in the heck are you doing in this 14psi auto swap thread? lol

 

Waiting for updates, duh

 

Yup lol.

 

i love how everyone hates on the a/t

4 speed FTW!
