Im not so much dissapointed. But im not happy. My car has what I believe to be an injector TICKING really loud. I think its going out. It also has a small leak on the header collector.

I forgot to mention. They said they had trouble getting a strong signal from my tach wire. Soon as I hit about 5200RPM the signal falls off bad. So I am thinking with the engine if I am PEAK HP higher than 5300RPM it did not show on the dyno. I will scan the dyno slip and show you what im talking about.

I am also throwing codes saying my O2 sensors are bad. I cant figure out why.

The car has more power than this. On the dyno they said they were loosing a tach signal from my plug wire above 5200 RPM. So the dyno only went to 5200RPM. I would like to think by the way my car feels it peaks HP closer to 6k. I am going to get a few things fixed and try a different dyno.

Hmmmm,that's a nice 40hp gain over what I've seen stock 3.8's dynoing but what happened to the torque?By the way,it would REALLY help if you had dynoed the car stock for comparison.Good luck getting everything straightened out.

I have the dyno graph scanned to my computer. I can show you guys but I have no place to host it.

Who can host this for me?

I'd be very disappointed with those results. Doesn't make a strong case for SSM heads to me at ALL. I'd just assume leave my stock heads alone with a monster cam.

wow dude, that's sucky; if you have a 3.8 that dynos 153 hp STOCK, your car has SERIOUS issues.

wrong. our injectors are supposed to tick. the louder the tick, the better shape they are in. if they aren't ticking your car has issues.

:( 30 more HP than me
;) I'll take your car

[pgriffith]

Listen to what I said. The car peaks HP close to 6k. The dyno only went to 5200RPM. I know it aint the greatest results but its a small cam. I wasnt expecting much and i am happy with it. Peak HP is higher im sure of it.

My injector ticks extra loud. I know it aint supposed to sound like this. I also have 2 bad O2 sensors.

P I vouge for yea...I can feel the power increase...Lets just get those few things work out and then get it dynoyed again...And log into IM...

[Noahs40]

I don't have alot of experience with dynos but I know that an 800RPM difference can possibly be 10-15hp difference especailly with heads cam that like to rev higher than stock at your peak HP...just my opinion though!
