LS6 intake

mac mids catted y pipe
42 lb injectors

This is an M6 car through a 10 bolt 3.42's through full exhaust and cats NO cut out.Maybe with a underdrive pulley and a ORY with a cut out hit 400??Guess pretty decent for a stock sounding car has no lope at all sleeper mode.I bought a NX MAF kit hopefully hit 500 RWHP :judge:

Ill post the dyno sheet later

I have the same cam, it is a nice little cam in my opinion. I did 370 with the 1.8 Crane rockers. Went to Dart heads and backed down to 1.7 rockers and did 393 with a dirty air filter. I am going to a FAST 90 next, hoping to get 410+.

Add a pulley,cutout,ported fast and a 90 and you'll add an easy 20 to 25RW.....
Does the cam have any adv ground into it...

Yeah i have a pulley havent put it on yet and my funds are limiting me to buy a 90/90.I spent $1300 on my N/X kit with all the bells and whistles ill have to wait awhile.I was thinking of maybe adding some rockers instead of swapping out the LS6 manifold

5* advance ground in, pushes power curve down so power peak is around 5,900 RPM. Makes for a nice little street cam that idles nice.

Tuned? What exhaust? Those are very good numbers. I tend to like short duration, large lift and no lope cams ... your's seems to validate my tastes. :) I would like to see a setup with long tubes and all the bolt-ons (EWP, U/D, etc ...). :cool:

Yeah before it was tuned did 357 RWHP and 357 RWTQ by a shop in so cal they messed with the tune to try to make it pass smog. The owner that i bought the car from said it did 380 RWHP but when i dynoed it did 357RWHP . When i drove it i knew something wasnt right because my LT1 car pulled harder than it. I took it to my buddies shop and we spent 3 hrs on the dyno i used Tunercats OBD II to tune it. Im by no means a pro tuner but i can navigate Tunercats ok ive used it quite a bit with the LT1 car i had.Im sure could get a little bit more out of it.I really dont want long tubes due to the fact im in CA and atleast try to pass a visual.Thanks for the comments!!!


Mac mids catted y pipe and a magnaflow muffler

Longtubes on a cam like that wouldnt pick up much....If there MAC cats I'd replace them with metal matrix cats by magnaflow as they would pick up power too.
