Do these numbers make sense?
I won't say the shop name but my car made 505 rwhp with the turbonetics turbo kit. Here is what it has done
A l99 to ls3 conversion with a cam (115+ so works with forced induction) 3200 yank stall full custom exhaust 85 lb injectors ADM FPCM zl1 fuel pump 102 Fast Intake Manifold Several Upgraded components on turbo kit. I don't know what psi they set it at, I pick up tomorrow but I assume 8 psi. Does that sound good or kind of low to you? |

your stall will hold some hp back but not familiar with your kit , seems low, but I have a L99 to ls3 conversion, Maggie with 8lbs boost , cam/headers/cai... with 22's on the back,,, and made 586 rwhp.

if you still have your cats that's holding back power too. im not sure how much the auto drives down your hp #. mine was measured on a mustang dyno.

Single or twins? Turbo size? Boost?
Lots of factors can influence your power level. Maybe they have it on a very safe tune. My camaro has pretty much same mods as you except stall and I'm running a maggie ... at 7-8psi i was around 580~whp.

Turbonetics is a single up top with U turn headers.
Seems way low but hard to say. I know all the AGP kits at 10-11psi are doing ~650rwhp on l99 autos with no other mods. No cam, no ls3 conversion, nothing but turbos and the fuel system to support that boost.

Yeah I was hoping for over 600 they did say the tune conservatively. I am going to add heads at another shop and have them retune then

Once again...get a base dyno and look at the gain...that's what you are after.

sounds like your on a VERY low PSI.
just about any kit we install with 8-9 PSI and ls3 conversion will do in the 640-680 RWHP range with a stall also. 91 OCT fuel will knock out about 20-30 RWHP if your a 91oct state. the cam has alot to do with the HP gains also. our stg 2 FI cam nets usually 80RWHP with just the cam on a FI car. We need more info. PSI CAM specs kind of dyno still its just a number no matter what. take it out to the track see what she traps that will tell you true HP |

Sounds a bit low, is it the single disc or triple disc yank. If it wasn't locked up at WOT that will affect the HP numbers on the dyno some.

you can also check the springs in your wastegates, make sure you are using the correct ones.
Blue Stripes = 5psi white stripes= 7psi Red Stripes = 9 psi with no additional preload from the set screw. |
