Ls4, fully ported blower, ported head, 82# springs, zzp stg2 cams, longtube, 3" catless.
Idc 80+% @ 7500.

Idk how that guy above is possibly running a 2.8 w/ 60's on e85 without going incredibly lean...

Id1000's were necessary for the build in progress.

 

u couldnt get away with running 80's and a refrenced fuel system?

 

No. I forgot to mention that. I already have a return style brfps. Multiple ppl are maxing out 80's on tvs setups only reving to 7500. I'll be shifting at 8500 with an overdrive crank pulley. 80's would fall far short espicially when inload up the e98 for dyno-ing.

 

Hey my car gets high 30s mpg hwy based on my dic but once calculated though the actual miles and gallons used i get 24-26 most! Only way a lsj is gonna get higher mpg is leaning it and increasing cruise timing to a damn good amount! And you still shouldnt be able to reach higher 28s (itll be difficult)

 

I am calling BS.

Exactly.

Its not possible. I would call BS on armcclure too but he does not know how to take constructive criticism and will probably blow off the handle!

lol

 

I usually get 18-20mpg in town. Occasionally Ill get 21. On the highway its usually 23 or so, but I dont take many trips so I dont have a real solid average. I did manage to get 27mpg once coming back from a car show in Minneapolis this spring though after my stock fuel pump died

 

SHUT UP ERIC!!!

Id injectors have some of the best spray patterns available. Using a brfps allows better control at lower idc's like you said. And teh math don't lie!!!!

 

Of course. Whatever you run on your car is the best...

 

If going down hill counts I can get unlimited mpg if I turn the car off but leave it in koeo . If I go by my dic it says 99.99. So I can actually get 100+mpg haha ..

 

Infinity MPG!

 

Naturally

 

a 2.8 maxes out my 60#s wen i bring the nos in..other wise my idc is like 85-90% @7500

 

for the build in progress i can see 1000's but for the current setup it seems as if 80's would do..but idk im only looking at it from an outside view

 

Yes they probably would have. I just knew that my goals would eventually pass them. That's whi i went straight to the 1000's. No need to spend the money twice.

 

Cobalt idle ID1000cc - YouTube

ID1000's idle like butter

 

That is pretty good too.

What do those injectors go for these days?

 

i got an insane deal on them used from an ariel atom guy. $350 with everything and they had 2000 miles on them

 

Daaang. That's a steal!

 

ok, you might be right, checked my interceptor instead and im at 25... now im sad, but i guess i could be worse! I would like to as well "blow off the handle" but im online, i find it wouldn't do much, lets just say i punched a baby!

 

18-20 city...mid 20's on the freeway

 

What mods would I need to get tuned to e85 only reason I would do it is because the gallon is cheaper. I'm stock lsj sc
