    Dyno Numbers seem low?

    I had my car tuned and dyno'd by Steve on Vector Motorsports mustang dyno last November after installing my new cam. I put down 391rwhp and 371rwtq. Steve seemed to think my 4.10 gears where robing some power so I didn't think much of it. In the past few months Ive seen a few cars put down better numbers with less mods on a mustang dyno. Im just wondering if vectors dyno just reads low or do my numbers seem a little low.

    Mods where at the time of dyno

    Ls6 intake with ported TB
    ESP 230/234 111+4 .600/.601 cam
    LS2 243 heads with thinner head gaskets to bump compression 11-1CR
    Hardened push rods and Pac 1518 Springs
    Jet-Hot coated LT Headers
    TSP True-Duals with Moroso Spiral-flows

    My Car M6 stock ls6 clutch it also had heavy 17X11 Chrome ZR-1 rims and it had 4.10 gears in a 10 bolt. Steve's tune seems spot on with a perfect 12.8-1 A/F the car runs great. Just wondering what you guys think about the numbers.

    Id say it sounds about spot on for a mustang dyno. 400ish on a dynojet.

        I was expecting around 420-430rwhp on a dyno jet with this new cam. There's been cars on tech with smaller eps cams and stock ls1 heads that put out over 400 down.

          Haven't got a chance to run it yet. Ill be running it soon just wondering what you guys thought. I will say the car does feel strong though. It just seems like my numbers are low for this cam.
          For example this car has a smaller cam ls6 intake and stock heads on a mustang dyno. http://www.ls1tech.com/forums/dynamo...ts-update.html

              ^ what he said.

              Did you dyno the car before you put the cam in? That would be a good comparison to see if its down on power.

              Seems 100% normal to me. 430 would be a very strong cam only car. Even for a 6 speed.

              Does the car have all the bolt ons?

                My car really isn't cam only though. The heads are not ported but I do have LS2 243 castings and thinner gaskets for 11-1 compression. Most people cam'd ls1's pickup around 25rwhp with stock 243 heads.
                If it was cam only I would only expect around 400rwhp but with the heads it should be more then that most of the time.

                  It's all about how it runs and the e/t at the track. Dyno numbers are just that, numbers and every dyno is different from what i have been told. With that said mine did put down more power than yours with a smaller cam, stock MLS gaskets on stock 243's and throu an A4 with a 3600 stall. I thought mine would have been more than that also but guess i will find out how it does at the track now that it has been tuned. Before tune i was at a best of 11.76 at 115mph. Mine laid down 409rwhp/393rwtq

                    If the car traps 118+ it will be right on target.

                        Where was it tuned? What kind of dyno? Ill take it to the track when I can but my numbers seem so down that somthing sounds wrong. Does vectors dyno read low?

                            Where's dyno day at? I'm hopeing vectors mustang dyno was just being stingy I've read it can be at times. Also steve mentioned my clutch looked like it slipped slighty at 4700rpm but he said he wouldn't really worry about it so I really don't know what it ment. I would assume if it was slipping causing low number he would have said something.
