Fuze Posted February 6, 2015 Report Share Posted February 6, 2015 if your fuel is good, the turbo will explode before a 12a will pop the gasketunless your head is warped ^^^This. That little guy has a hard time hurting anything, when it's boosting over 15-ish PSI it's almost just heating up the air after that, no longer efficient at just 325 CFM.

Minagera Posted February 9, 2015 Report Share Posted February 9, 2015 All of the boost. FYI: The TDO5-12A-8CM2 320 CFM @ 15PSI, which is about all that turbo is good for anyway. Link to comment Share on other sites More sharing options...
Shelby Posted February 9, 2015 Report Share Posted February 9, 2015 to get a real world answer you need to read the exh manifold back pressure , performance from even a stock 12a will be increased by doing a heavy porting of the exh housing and waste gate hole , but realy your limited by the intake air volume as to exactly how much the 12a can push any boost surge from a 12a with MPI is due to the restricted waste gate housing truth is ALL mits tubos need porting and bigger waste ports this is true of all of them 12a to 20g Link to comment Share on other sites More sharing options...

freebird Posted February 10, 2015 Report Share Posted February 10, 2015 (edited) drill a hole in the firewall.hook a pipe on the wastegate arm.push on it real hard..... .....real manual boost control...works really well. Some guys say their 12a boost's over 20 psi.....But i think they need a more reliable boost gauge. Also if your not running the 88/89 ecu....boosting sucks over 7 or 10....I dont dare say fuel cut or this thread will be on another topic....lol Edited February 10, 2015 by freebird Link to comment Share on other sites More sharing options...

Shelby Posted February 10, 2015 Report Share Posted February 10, 2015 many 12a's have lasted past 100k miles at 10 lbs boost ,, increasing the boost lessens the turbo's life , doing 18-20 lbs boost on a 12a don't do any thing but push hot air and kills the turbo bearings Link to comment Share on other sites More sharing options...

Fuze Posted February 11, 2015 Report Share Posted February 11, 2015 I think we all just cranked them up to 15-16 PSI and when they eventually blew an oil seal we'd go to a 14G, then rebuild to a 16G, then rebuild to an 18G, and they would all fail the same way lol.

IntercooledFlatty Posted February 12, 2015 Author Report Share Posted February 12, 2015 set at 10 psi 12a singing happily it just feels like it supposed to be there and should have been from the factory... along with MPI, 3" exhaust, s16G, etc. on to the suspension Link to comment Share on other sites More sharing options...
