The dyno software prints the graph out of place. It was fixed for a while when Dynojet updated the software but had other glitches in it so I went beck to the older version.

If its a big deal to everybody I can e-mail the graph to Mark so he can repost

The last graph posted, for clarification, is the pre and post install of the Dart heads only?

I believe everything you say Vince, I guess I just didn't understand what you were saying. To me it sounded like you were saying the printed numbers were one thing (SAE or Actual) and the graph was something else (SAE or Actual). Sounds like I totally misunderstood. I didn't realize that the graph was neither Actual, nor SAE, but a lowered version of SAE. It's all good man!

The last graph posted was the gains to get me where I was before the heads. The last graph was to show where the car was after the cam install. If you look at the baseline in the first graph it is 423 rwhp 405 rwtq, the second graph ends at 423 rwhp 408 rwtq. I was just showing that the graph axis was off on the first one and the numbers were correct though. The air fuel was around 13:1 I believe.

Great numbers.... what cc are the chambers and what head gasket are you running? What compression do you think it is?

That's because DART's CNC program isn't out yet. Others vendors are using their CNC program and running it through the DART casting. Just like TEA does with AFR's. Results should only be better when the DART cnc program starts running. I highly doubt they'd release a more expensive option that produces less results.

The heads are 61cc's with MLS .054 factory gaskets. The compression is about 11.0 cr.

Well I guess if PV isn't and issue with this installation, it won't be with my little 216/224 .581 .581 115 LSA cam.

No, you shouldn't have any problems with that cam!

Looks like the Dart heads might have a little more free drop anyway.

Assembled, i.e. valves and springs, etc?

Give Futral or another sponsor a call & see what the going rate is. They are making x-cellent HP & TQ according to all the feedback, especially for the price.

Those outta the box heads basically made 25hp/25tq gain on a car that already had a host of bolt ons AND a hot dyno-tune. Seems like $$$ well spent - especially if you consider what the gains could be on a bone stock car. After add ons are in place it is harder to gain efficiency because (hopefully) the add ons already made the motor more efficient.
