me to besides that crack everything else is fine what else is it no signs of running lean or anything

 

how much timing were you running and what psi? iat-2's? and by any chance did you have a egt installed if so, temps? i think thats what area47 meant by heat, egt's... correct me if im wrong

 

Been cheaper to put a bigger intake, build the motor, and get a tune. Now you have to get a new motor plus build it and tune.

Hopefully block and head is ok.

Have a feeling it was in the tune.

 

paul tuned him... and paul is pushing 414whp dd but 1 important difference.... he has the hahn intake manifold...



hey paul with the 60 trim do you fall completly out of the powerband when u shift to the next gear cause of the shity cobalt gearing... thats what your latest video on streetfire sounded like...

 

welcome to the ranks of turbo build then blown......

I can't wait to build up my motor. Just want to pay off the debts I have first. And quite a bit of the car too. Wouldn't mind seeing my payment under $200

 

yeah unfortunately, but mainly because the WOT box wasn't working. When it does work I don't lose boost btwn shifts.

As for the tune He was running 20.50 psi, 23 degrees of timing, and Meth injection at an 11.7:1 afr. Car was running great, did like 15 pulls on the dyno last week and no issues, just a freak thing I guess. I dunno, my motor is still fine somehow.

oh yeah and I still do use the car for dd use, it was fun yesterday since I'm still on the racegas from Friday night (gotta love 35+mph lol) spinning 3rd on the highway sure scares the **** out of people.

 

if you read the post right i have another motor thats the only reason i pushed the car like i did man car was great no tuning man to much air into #4

 

wow so even at that boost level the meth was letting him get away with 23 degrees? thats impresive...that the 1 reason im keeping my meth although i went hahn level 5

 

Yeah that's why I'll be putting meth back in my car, I can only run 17.5 degrees under full boost which depending on temp is usually 20.50-21 psi.
but yeah it was definitely not a tuning issue, car was setup perfectly, just one of those freak things we attribute to the stock intake manifold.

 

thanks for the quick replies!

 

I still really dont think its an intake manifold issue...thats just me

 

well no-one has solid proof... but i've yet to see guys running the hahn or saab have a problem but anyone who attempts to push the 375whp envelope with stock is having issues it seems... thats reason enough for me! plus paul picked up 64whp by swapping out to the hahn intake and intercooler so there was obviously a huge restriction in the manifold causing un even air distribution and heat issues


but in all honestly when your dealing with stock hyper pistons ringlands are an issue no matter what set-up

 

leave it be mr.
leave it be.

 

That's when he also swapped in the 60-1

 

yes but his previous turbo was up to the task as well... he just needed a new turbo anyways cause he blew his old 1 right... im not sure i dont know him, this is just info i'v gathered over the past yr... what was his previous a 50 trim correct? not searching just going off memory so i could very well be wrong...

 

I think it was a ebay 57 trim he had before. Not too sure though.

 

thats sounds more like it i just remembered e-bay and 50 something...

 

yeah it was a .57 trim ebay turbo

the hahn manifold is key I swear lol.
but seriously there has to be some explanation to my car, that's all I can think of. chris was running almost my identical setup, tune is close to the same, just little more timing up top, same fuel pump, injectors, I dunn

 

I thought the gain was from the intake mani, new turno, intercooler, and more boost all at the same time?

Either way i got forged goodies for pistons so ill rock that stock lower intake manifold all the way thru 400 wheel lol

 

ok... did you gut the mani... (remove cores) and run a front mount?

 

all stock intake side cept i blocked off the m62 snout and removed the rotors. no front mount, lower intake manifold is stock

 

forged pistons should hold up.
and it was with the new turbo but same boost levels, just a little bigger turbo, better manifold, bigger FMIC. still fantastic gains all across the board (picked up a lot more mid range TQ too)
