Half Mile Predictions - M1000
Was the 881 on pump? I ask because looking at you build, I would expect 1k plus whp. I made close to 800 on a stock motor w/ c16. I had every possible bolt on but only ran GT 30s.
I have not read the whole thread, so excuse me if the Q has been answered. In fact I only clicked on it because I saw that our dear Walnut posted. I have not been harassing him enough as of late. Better yet, has he and BHT been having lovers quarrels during my absence.?

No 881 is on the E85 i need to replace my Waste gate springs as they will not hold anything over 24psi. like i said in the first few post Sean i dont plan on making a Dyno monster i want 1000whp that has a Conservative tune. you can have all the power you want but if you cannot get it to the ground then whats the point. I'm thinking BHT has the right formula... NOS!!!
higher then pump. Looking at my ProEfi logs compared to my "tune"
on the factory ecu, it's actually milder on the PorEfi and I'm making
150-200 more hp!
Corey, I believe that aggressive tunes are responsible for a lot of blown
headgaskets, reported and unreported!
We added 7 lbs of spring and gained 5 lbs of boost on this setup
You can go fairly aggressive on timing up top if you are comfortable with your tune (of course there is a point where hardware failure is imminent). The mid-range area where you making the most cylinder pressure getting hard/****y on any fuel to make a bit more HP/TQ will end a motor/gaskets life. E85 it happens a lot more because you have a fuel that because of the burn properties allows, in most cases, the spool to be quite a bit faster than it would be on C16/Q16/etc. So because "its safer" some think having that huge spike there can't hurt anything because the fuel is protecting. It is from detonation but....

spot that is using the most fuel. This ALWAYS correlates to max load. You can
"pull" timing out of this area ( for us it's around 4k) , keep the boost linear
and slowly add timing as rpm increases. It's a meticulous process but it
keeps things safe and you'll still pull like a freight train to redline!
+1 on the conservative tune. Rule of thumb on e85 is about 6 degrees
higher then pump. Looking at my ProEfi logs compared to my "tune"

150-200 more hp!

That's a good question lol! The wastegates came with 7 lb springs! Couldn't
get past 22 lbs on 'em. I misspoke, we had 7lb springs and added 9 or 10 lbs
We kept them but added another 9-10 lb spring. No one was quite sure
28 lb pulls back to back ( and no boost leaks knock on wood)
Corey, it's probably safe to run about half of what you want to target.
e.g. 28 lb boost = 14 -16 lb spring. Assuming you are running 44mm
gates. Again, no expert here but I think? this is a good rule of thumb.

Made a beast 1050-1075rwtq but basically same HP (1130-1150rwhp) that it did on 34-36psi. Damn intake LOL!
Nice. I just picked up small Blue to go with the Large yellow witch will give me 1.2 bar
omg I can't stop raving about it. It tracks straight as an arrow no more dippsie doodle when I get off the gas It is amazing.
Good question. I have to see what Matt charged me after. I will PM you
