Ive had my car since June of 08 and tuned since march of 09 without a single problem. Its fully bolted and tuned. I did not do a single thing to my fuel system because i am not running a bigger turbo. Ryan (scythesnake) who is pushing 542whp out of his cobalt has the 5th injector added and some other goodies from ZZP i cant remember right now. Listen to us man and dont spend money that you dont have to. A turbo swapped LSJ will run different AFRs than your LNF. Those people obviously have little to no experience with direct injection. But hey if you wanna throw your money at them and blow your **** up then be our guest. In for the "oh **** i blew up my motor" thread

 

I will tell you what I did on a dynojet. Here it is.



The mods are Intake, upper charge pipe, intercooler, BPV, highflow catted DP, 20psi BYT tune.

More than likely im making a bit more with my 24psi BYT tune now. clutch slips alot easier, lol..

Re-reading your first post, i'd say you should be able to make just over 300whp but the dyno numbers are right on.

 

As am I

 

ok got you, appreciate it!! will wait til after the tune. That is my main focus right now, so i can rule out the cams for now, just tryint go get a mod foundation for this car. As far as tune been looking between the HP and trifecta but from wut everyone on here is saying i rather the trifecta then that shop tune my car!!1

 

running a lil lean til i can get a worthy tune/ this BSR is a lil sketchy

wut is BPV? ByPass Valve? y not just get a BOV?

 

**** all Hahn. I'm in the stage of replacing all **** lol that was Hahn.

 

Y is there something i should know bout Hahn? i mean the car came with all the hahn pasrt on it when i brought it Car runs good no problems and no problem when my friend had it...besides this tune everyone tell me is shitty which is a easy fix..but the exhaust sounds real good and so far no problems from the other products...but clue me in if im missing something!!

 

Here it is.my car was hahns tester I guess you can say.I bought it with all hahn mods. Can you check my Sig out.ill pause for a bit because it was all hahn.............................................. ........



The only good thing Hahn makes is there downpipe and exaust and it even rattles. All there parts are made with steel. So therefore rust. Also there innercooler is junk simply said. I blew my endtanks off more then I have fingers. Which is 10 lol. But I've broke the endtaks themselves 8-9 times. Simply put. Zzp and treadstone for parts or you can go with turbotechraci.g for vendor parts. Aarons great.

 

Horseshit.

12.9 afr in some instances can achieve slightly higher peak hp, but is definitely not optimal for engine longevity or torque.

Run an afr in the 13s and your engine isn't going to live long.

 

Lol. Andrew look at Ure afr commanded please lol.I have you at .83-.84.. reasoning.g is for melting.g pistons and blowing ringlands. Yes it create more power. It is unreliable.

 

Im on the stock turbo, I dont need a BOV. The stock turbo has an integrated BPV in it. I just replaced the rubber diaphragm BPV with a forge motorsport piston style BPV. Less likely to fail, and sounds cool, plus interchangable springs (although I probably will only ever leave it on green.)

pics.

 

Nothing wrong with Hahn except they dont support the cobalt community anymore, their parts are way over priced, and sometime unreliable. One thing everyone here will proclaim is that their exhaust does sound good.

MPx, BYT, TRE, ZZP among other vendors on this forum are some of the best places to find aftermarket for the cobalt ss. The cost is better and even the quality is better in some cases.

Have you ever seen an after market intercooler blow up (not bottom out but blow a hole through the sheet metal endtank)? I have. It was a hahn one. There is a pic of it somewhere on this site.

 

AGREED dude i got banned from here for a few days for saying that like a year ago haha... they fucked me over big time. They use to be right by me and i was gonna have all their parts for the HHR SS but yeah we all know how they keep their promises

Oh yeah and **** the BSR tune. Find a good tuner and get HPTuned. There has to be someone around you look in the regional threads.

 

lol that's a dumb reason to ban someone. why you get banned from hhrnet





edit: agreed with the hahn thing too.....and the bsr thing.....i had a bsr that i got when it first came out in 08 and later somehow it wouldn't sync with my ecu when i tried to reinstall the tune. hahn was no help and bsr said my customer service period of 2 years had expired and i would have to purchase 1yr of cust service for $75.........i bought hptuners instead lol

 

What a joke

 

some dude was talking some mad **** about something so i told him how i really felt and they said bye bye.... oh well that place is a joke anyway

 

haha....yeah it does kinda suck over there. i

chevymgr over there posted some things in a thread i started that was very ******** like and i told him to put his big girl panties on and quit acting like a schoolgirl. he started pming me all this bullshit and i told him it's ok when he says something like that to me and i say something back then of course im wrong and he is right cause he's a mod. he threatened to ban me and **** and i was like whatever. things calmed down and he said that i made him laugh and we squashed it. i thought it was total bullshit either way.

 

im on here and gm sport compact i go on hhr to get some laughs in cus its the same threads over and over again

 

yeah it is definitely the same **** over and over.

 

I've got that same wallet! Yours probably has more money in it than mine, though.

 

You have badbaltguy's old car, right? Man, that dude was infamous on this site.

 

Yeah he was him and all the problems that car had

 

Lol yeah. This car is actually built now lol and running a totally different setup lol.. old setup and previous tune that i bought it with sucked bad... So I fixed the ****

 

Can't wait for you to be able to fix mine to

 

i can agree there is some rattle coming from my exhaust just thought one of the pieces holding it up maybe broken or sumtin wont kno for sure til i get under there, the intercooler no problem(yet) by how yall are saying right now should i drop my bumper and check it??plezd with the intake

also the forged bpv is that a worthy investment? or just a reliability thing?
