I am trying to tune in my VE table for my car and I need a HP estimate from anyone who has a dest top dyno. The megatune creates a rough table using the peak hp and peak torque at their respective rpms. Right now I am using 280hp @5500, and 315ftlb @4000. I think they may be alittle inflated though.
Its a 283 sbc 60 over, 292ci. flat top 4-valve relief pistions with 55cc mid 80's 305 heads, I am thinking about 9:1 CR. The heads have stock vlalves with mild porting work. 1 5/8" primary headers into 3" sidepipes. Tuned port injection manifold, bank fire. The cam is a summit 1103, 214/224 duration @50 .442/.465 lift @50 advertised 272/282 112 lobe seperation.

any help would be great!

Here's my results. I think I might have skewed the results a bit with the induction size, not sure. I've found that these things when modeling TPI are pretty inaccurate, you'd get a more likely result with carbed modeling. Also, I totally guessed on the stock 305 valve sizes. I wouldn't have a clue...they don't have Ford stamped anywhere on them =p.

Good luck!
