301whp from a gt2560 at 11psi...yeah right

I have a hard time believing this crap.

I'd love to view the dyno but I can't handle all of the dumbasses on there enough to create a login.

I do agree with all of the guys of miata turbo that are showing +/- 250whp at that boost level. FM always has the unbelievably high numbers, so not really surprised. Considering the altitude they are at, it's really hard to believe.

"Swedish dyno" - I'd like more info on that.

I Googled a bit and came up with a Swedish MPS Dyno, that was known for reading 15-20% high compared to a "roller" type dyno.

The interesting thing is that this dyno apparently reports a better output at the wheels than has been quoted for the crank output.

Looks like this -

most 2560 cars with 99 motors take 12-14psi to make 250whp. I don't know why they post this shit up. Apparently they need to have their Dyson dyno serviced. Is it yellow?

While Skip's Caterham might've shown 302whp on the FM dyno (he showed me the printout FWIW), it was the slowest of the Se7en replicas on the li'l kart course they were using for the track day. I'd be more than interested to see comparative dynos and related vehicle weights between his Cat, the FM Westie, Keith's Locost and Brandon's ultralight.

Skip was the slowest driver.... Keith and Brandon drive/race their cars and have lots of track time. My dad rode in Skip's car at the open house after the Hydra was installed and couldn't believe how fast it was.....In a straight line.....

hydra didn't make it fast, tuning did.

And you know this how? Jeremy tuned both of 'em. So are you saying the tuning ability with the Link is not as good as the tuning ability with the Hydra? Wouldn't that still mean it was because of the Hydra?

FM has data and you have an opinion (and over on Miata.net Keith suggested you could even ignore the absolute values if you can't bring yourself to believe the numbers). It's pretty clear Skip's car made way more power with a Hydra than with a Link, same day, same dyno, same car, same tuner.

simply put, if spark and fuel values are optimized, what is Hydra doing that makes so much more power? Something else had to change.

Hey Curtis, dad said you had guys had a good time and you were looking for a miata again. Glad to see you made home safely. That was a long trip you made!

[cwisenheimer]

Yep, it was a great time and a looooong drive. I had to make it back in one day (6:40a departure, 1:15a arrival). It was well worth it though. Saw lots of great scenery, two car museums, a car show, racing, free Wiseco pistons, etc., etc. FM knows how to throw a party.

Because the Hydra has many more zones for tuning than the Link does. The link only has six rows, and the tuning is for every 500 rpm's, there are many more on the Hydra, it also has more resolution than the Link. This is why the Hydra is better. It's like HDTV vs Analog TV, so the Hydra catches all the tuning points in between what the Link can do.

so 14x6 resolution sucks and all, but who else do you know with a gt2560 who's making anywhere close to 300whp on a cast manifold? I know of a guy on the internet who makes 300whp with a crazy tubi manifold and 17psi, nowhere close to 11. No motor is that much of a freak.
