DD2005 results for my motor
Well this is what Digital Dyno is stating what I will make, I was hoping for little higher numbers!!! O well, I know that this is just an estimated number. O one more thing; when I bought the car it already had aftermarket injectors but I have no idea what they are rated at. Does anyone know a good way to find out? Ok well if you guys have any comments (good or bad) let me know. O and yes I will get an aftermarket throttle body but Ill do that a little down there road. Talking about that DD2005 also stated that I would only make an extra 10hp with a TB that flowed at 1000cfm (stock tb is rated at 650cfm). Does that sound right to you guys?? Well just let me know what you think.

Ohh. DD2005 looks impressive. Things like being able to play with ignition timing now looks promissing plus a few other options that were not available in DD2000. Looks like another program I need to get my hands on.
I see in your screen capture that you have crank timing for ignition. Your engine uses a crank trigger to fire the ignition?
Increasing the CFM up that much normally won't show a big increase in performance but you would probably notice a big change in the way the throttle response is in the real world. It also depends on how much the engine really wants. At only 10.2 compression, a bigger CFM would like more compression, cam, heads.

Thanks for the feed back Stephen87IROC. To answer the timing question I actually don’t know what is used for timing I just picked it. Something I need to do more research on. Currently my ignition is stock planning on upgrading after my car is running and have some money again!! I’m sure you guys know what I’m talking about! I really wanted to go with a higher compression but I want to use pump gas, as for now this will be my daily driver. This explains why I got a smaller cam as well. When the times comes close for my car to fire up for the fist time Ill be in here again asking questions about timing. Any suggestions were I can start researching this topic? But thanks again for your input.

Since I don't have DD2005, I don't know what options are available for all the choices.
Your base timing of 8* and total timing for 36* should be pretty close. Try dropping the total down a couple of degrees and see if the HP level increases. Finding what timing works best is almost a trial and error method. What works well in one car might not work fo another.
My base and total timing is 36*. My distributor is locked out to full advance. Is it the best position? I don't know. The best place to find out is on a dyno but now with DD2005 giving you a timing option, you could probably get very close to what the engine likes best before firing the engine up.

you get 5 free runs on the full version for free.
My trial version has been running for about a week, i still have 4 more "runs" left. As long as you keep the program open you can do as many as you want!
