    so I’ve been trying to find an actual dyno sheet (not virtual) with comparable parts to what I have. Yes I know there are still a lot of variances from car to car but I’d just like to see an actual sheet with a similar set up. From what I’m reading my car should be putting down around 350 to the wheels. I personally don’t think it feels like it’s even close. Anyway as I was looking at different sheets I noticed most were done in STD instead of SAE. Any reason for that?

    The only place you'll find a 350whp k04 speed 3 is on a high reading dynojet running ethanol haha. 1.01 CF on v dyno is kinda in between a mustang dyno and dynojet.

    also Virtual dyno has been developed along with dynojet, dynojet numbers and VD dyno jet numbers of the same run have been proven to within a few HP / Ft Lbs of each other

    Dyno sheets are really only good for a before/after comparison in my opinion. It's fun to say "I make XXX whp" but at the end of the day, it'll be your trap speed on the track that shows the power you made in certain weather conditions.

    Your best bet like @Awafrican said is to get some good CLEAN 4th gear logs on a nice straight flat road and vdyno them and see what they say. You'll at least get a nice picture of how your HP and TQ curves look.

    A solid 4th gear log will tell us a lot about what kind of power you should be making. What are you mods? Even more important than dyno max number is room under the curve. The KO4 can hit hard and then drops off, this is fun to make your car feel fast but it does not mean your car is fast. Post a log so we can check it out.

    Also don't listen to @andale927 his car is super slow.

    I tried to run the virtual dyno on my laptop at work but couldn’t get it to work. Not sure how to post a log here. I could email it to someone if they can figure out how to post it or whatever.

    Car has 3.5” intake. CorkSport FMIC. 3.5 bar map sensor. Fresh injectors with CorkSport injector seals and new o rings. Grimmspeed 3 port ebcs. CST4 turbo. Cobb turbo back exhaust. PD tuned to 24psi on e30

    Ah idk why I assumed k04. Shoot a couple logs over using Google drive or datazap.me, you can also just upload the .csv file in a post by drag and dropping into the reply box.

    Yeah sorry man. You might as well be speaking Chinese to me. I’m computer/forum stupid. That’s why I don’t post shit on here anymore. People get all weird when you post something in the wrong place or say the wrong thing. I don’t do well with sensitive people so I just try to read and figure it out. I’ll work on trying to get it posted. Thanks for the help though. It’s always appreciated
    When I say post shit on here I don’t mean this site. I mean the computer and forums in general. Everyone on this site has been extremely helpful and the amount of info on here is priceless when you start out on this platform

    That was the last log that I sent in. I haven’t had a chance to do a log on my final map

    Here you go, it does look pretty close to expected for an e30 tune with no aux fuel. I assumed stock tire diameter.

    FWIW, I rolled on a dynojet when I had a CST4 on e30 in my genjuan (also PD tuned by Will); VD told me 365whp, real DJ showed 375.

    Looks exactly what I would expect from CST4 and e30 I made 375/375 on mine. It's a fun turbo.
