Mods are in sig Dart pro 1 CNC heads, Tr cam 233 238 on a 112+4 .599 .601" lift, Ls6 intake, gears ect.

I ran cam only for a while I am sure it was 400 whp cam only, but after I put the heads on the car is wickedly fast, noticbly very much faster then it was cam only I was expecting much higher numbers but the car still runs awsome. I dont understand because dyno wise its pretty much the same??

(my injectors were maxed out, and notice how the graph flattens out is telling me something is choking it off. Maybe the LS6 intake????)

If not the screw the dyno the car runs great I cant complain i guess

I was thinking maybe a Fast 92 or that weiand intake has anyone heard goodthingsabout that yet???


by the way they heads are 250 cc intake runners so all my power is up top

Nice flatline you have going on there. Either it's not getting enough air or not getting rid of it fast enough.

Take it to the track and get some numbers. If it runs good like you say, who cares about the dyno?

getting rid of it isnt the problem i dont think even though I have a catted Y pipe I beleive my intake is the problem I was just getting other opinions,

As for the track putting the heads on the car made it useless on the nittos, before they hooked just fine now its like im on ice they just spin 1st through 3rd and even from 45 mph roll the car fishtails I need a better tire now but I do agree about the dyno numbers it means nothing its all how it runs I would just like to see more you know.

any suggestions with my setup is appreciated intake/ cam/ exhaust wise would help greatly

Nice flat torque curve. Probably making torque sooner and carrying longer so it feels (is) faster. Have your old dyno sheet to compare?

you already answered one of the problems.....your injectors are maxed out. How will it make more power if you can't supply enough fuel? The LS6 intake will push way more than that I know personally so I really do not think the intake is holding you back. Dyno's are really not meant to tell you how fast the car is anways. With a dyno you get a baseline...whatever it is....then tune it to get the a/f, timing, etc dialed in. The TRACK is where you will notice the difference. Too many variables on a dyno.

point well made traction is just my problem at the track now though but it will run better im sure

as for cam dyno graph I dont have it but I wish i did my trans wasnt broken in when I had it tuned cam only

My vote is injectors

+1 on injectors and you'll also notice some decent gains with a Fast setup too.

What exhaust setup are you running? This could also be holding you back some.

I put down 402rwhp and 375rwtq with Fast/NW 92/90 setup and a cam (231/237) thru a 9". My rest setup is in my sig.

my tuner said get a fast 90, or 92 with a z06 maf that is alot of money but I wonder if it will be worth it after I get the injectors??

also I am forging my lowers in winter would anyone reccomend 11.0 compression for a frequently driven car???

Pro 1 cncs have like a 250cc intake runner volume? If you only picked up 5hp, NO trq(imagine that,35ccs to big imo) you have other issues. Take it back with your tuner, put a f/p guage on it also.
