just got my car tuned and i thought this seemeda little low. i was hoping for more around 400 by 15 or 16 psi but that doesnt seem like that will happen at 365 at 14.

 

Damn on stock ports

How much more HP do you want, that is good enough

what specs???

 

I'm deleting this because I have absolutely no knowledge of the circumstances that led to the failure. I can't put my ***** out there like that and vouch for someone like that and have you say something that may or may not have anything to do with them. All I know is that Mobley got 175 track passes out of it, and I feel for you if you bought a car that didn't have much life left in it. I'd love to hear more about what happened.

 

its a T61 divided housing with a Q trim. oh and yeah i have bills old car but a differnet motor. the motor that was in it chipped a seal back during spring break.

 

good numbers. Stock motor with a TO4b had 325 @ 14

 

it could be that the Q trim is to large up top and you need a smaller p trim with stock ports?

 

my t61 with street porting and a 1.0 t4 exhaust housing made 356whp at 11-12 psi. so your numbers seem pretty close. The t61 dosent start becoming efficient until higher boost so when you start running more it will wake up alot.

im running 17psi on mine now, havent been to the dyno yet but im certain im well over the 400 mark.

 

turbo probably isn't awake at 14psi...you need to be 17-19psi to get full benefit from a turbo that size.

 

i guess that makes sense but i will have to run race gas at that kind of boost.

 

why? i run 93 pump, 10 degree timing split and 14 full degrees of advance at 11:1 around 5k tapering to 11.5:1 around 7500

havent blown the engine at 17 psi yet

 

I run 93 oct with WI and 17psi all day long as well.
