That is also true. The article has the dynojet graph that plainly says the correction being used is SAE so that is not a valid excuse for the discrepancy..
Thing is, the ONLY reason anyone would post STD numbers is to inflate them.

Take the car to the track and see if it works.

So the 1.7's are putting you 230/236 .578/.589 right?

either way a 35+hp gain from a cam swap is still pretty legit.

Yup and thanks...

Quite a bit of mustang dynos actually read higher than dynojets since its so easy to manipulate the #'s. Dynojets are fairly consistent since its just spinning up a drum.

Because NA motors are immune to damage from detonation or melting pistons from running lean. It's sad that a sponsor who does tuning would imply that.

no they are not, but they also do not instantly blow-up either.... you're making it out that its a surprise it didnt blow up, and adding nothing to thread....

agreed the car wont self destruct at that point n/a unless you have wy to much timing in it to begin with.

I have never heard of or seen a N/A motor blow up from running 15:1 A/F

I have seen plenty of cars dyno with a lean A/F similar to that and none had issues (except for not making max power). Now if he was running 16:1 or more, I would certainly lift off the go pedal.

Just my experience.

Maybe I missed it in earlier posts..

Is the a/f 15.1 due to the old tune for the hot cam? Or did you get a mail order or something? Just kinda wierd to see a mail order tune end up that way is all im saying lol.

There's no reason to continue the pull once you see the 15:1 a/f. Any competent tuner would abort the run and add fuel before doing a full pull. In fact that's exactly what my tuner did when he was tuning my dad's LS1. A/F was 15:1 and it ended up being a 500 rpm dyno pull since he got out of it right away.

Sorry, I'm usually never a sponsor nuthugger. But I'd put Ryne up at the top of the stack as far as shops/tuners go. On a side note, I wasn't aware speed_demon24 makes a living tuning?

Seems legit

The Hot Cam tune was 12.5-12.7ish. When I added the new cam It went to 15.1... Now its set at 13.1ish.

I told him to dyno "as is". I'm pretty sure Geoff at EPS would have aborted the run if it was unsafe. He's been tuning F-bodys since they had chips. I guess other tuners would abort to be safe because they know no better.

Great numbers, that's an awesome gain!

+1, but I don't think a lot of people realize it happens sometimes. Gotta find a trustworthy shop.
