Re: Dyno'd today, thanks Locobob.
Cams, ported heads, open up the plenum and IH more, 15# flywheel, lite weights pulleys.
451 rwhp, 403 rwtq. 520 hp figuring 15% loss. Running a little lean, hit a peak of about 13.9 a/f. Last edited by efnfast; 06-18-2017 at 08:44 AM. |

Re: Dyno'd today, thanks Locobob.
Dom, it was SAE corrected.
Land and Sea dyno that he tells me runs very close numbers to the Dynojet. I think when he corrected to Standard I was about 478 rwhp, or 562 hp. I like those numbers. Next time I'm going to ask him to do it in first, just for the fun of it. |

Re: Dyno'd today, thanks Locobob.
When I talked to Pete about the 13.9, he custom tuned with a bung on the headers, the dyno guy used a sniffer in the end of the tail pipe. So there might be some discrepancy there.

Re: Dyno'd today, thanks Locobob.
For mostly the same mods, my #1727 car puts down 434rwhp, 366 rwtq on the dynojet. And a consistent 400hp on Mustang dyno. I'd say you did pretty good.
...must be those new Fog lights giving you the extra ponies...lol

Hi Steve
Those are good numbers now imagine if the cams were not split intakes and a little bigger like my intakes  About the sniffer on the tailpipe if you have small exhaust leaks it will cause the tail pipe sniffer to show lean. We do need to make sure all is good. Glad to hear you are enjoying her. Pete
