hey guys here my dyno sheet for my cobalt ss now. its an 09 LNF
325whp 368fttq
my mods
zzp intercooler
hahn lower pipe
injen hotside
k&n typhoon
gms1
hp tuned 25 psi
turbo tech intake manifold
3" catless down pipe.

I was wondering what long term results and effects of e47 do. and how well the car has held up. I really want to run it. cause I live in central to midwest indiana so I can find e85 everywhere, I just dont want to commit to the e85. after this im going big wheel k04

 

ive ran E47 about 2 years ago for a couple months and ive been running it again now for about 6 months and i absolutely love it. you can tell my numbers in my sig btw thats only on 22psi too. its great stuff and if its readily available all the more reason to use it man. some say to upgrade the seals on your injectors to run e but i havent done that and im fine. it cleans your valves as well so the whole car itself runs so much better, only down fall from running e47 is since you cant keep your foot out of it you burn gas a lot faster haha. also if you have a nice tune that the boost ramp is nice youll save your tranny as well as your clutch.

 

It doesn't clean your valves on a direct injection car. Other things you said are correct tho

 

oh my bad op, i always thought from something i read before that it cleaned the valves, my fault for the miss infomation

 

It helps with port injection, but we're screwed with direct injection.

 

okay sweet, that's the info that I'm looking for then, Id definitely be happy with numbers like yours hawkssoccer11. id say that would be pretty good for stock turbo.

 

gotcha my fault lol. yeah looks like only thing we can do is walnut blasting lol

yeah youll def love the E47 man, trust me the car is completely different and here this winter im hoping to get the K04r big wheel upgrade and run some e and shoot for 390-400whp with but its def gonna be close and idk if i can do it lol.

 

that is pretty much my plan is by next year is to get the big wheel k04! its just cheaper right now to do the tune for E47 lol

 

the exact reason why im running e47 as well lol. its a great power adder for how cheap it is, only thing some people complain about is having to put say 5 gal of e in and then 5 gal of 93 in. its not that bad esp if you know how much you can put in lol

 

how much power gain do you see when using it? like what were your numbers with and with out

 

on 93 i made 323whp and 355wtq that was also at 22psi just like my e tune. i was gonna do 25psi and add 3 more degrees of timing but i made great numbers but just fine tuning the **** out of my car so i was super happy. so thats +34whp and +20wtq by just switching gas on a stock turbo lol

 

oh damn alright so I have great numbers to look forward to then! haha

 

oh hell yeah man, as long as your tuner knows what they are doing you should be good to go man lol

 

Take my VD numbers for what they're worth but on my e47 tune my last pull put down 362/405 on 24psi.

Still averaging around 25mpg for the most part

 

damn makes me want to turn my boost up hahaha

 

Gm need to do like Frs and brz, direct and port injected, gunk problem solved

 

The new wrx is gdi-t, with port injection for the valves

New Sti is still the same port injection motor they've been using for 10 years

 

damn those are some fantastic numbers I might turn mine back to 24 and run it then! hopefully getting this done next week

 

Best "mod" you'll ever do.

I had a K04R turbo and ended up selling it because I'm more than happy with what the car puts down with just bolt ons and E.

 

so should I even bother with a big wheel k04 then? cause that was going next and final mod

 

There's never a "final" mod lol. But get your E tune dialed in and see if it's enough for you.

I had the turbo before I switched to E so I made decision afterward. Luckily I got what I paid for it so no loss

 

hahah this is true... I just didnt know what to do with it after the big wheel turbo.. haha possibly cam but Id only do that after i got a second vehicle

 

you should have ran e with the K04r lol that thing would have hauled some ass lol

 

I wanted to hit 400whp really bad and I had confidence that the k04R and E would get me there but at that point your maxing out the turbo and the fuel system and no need to cause more strain/heat then needed.

In the end it's all just bragging numbers anyway. It's all about power to weight on the streets.

 

thats my goal is 400.. so have you hit it? and what are your suggestions and what does your mods list mean by term 2 e47 tune
