GEN 2 HELP!!! Raptor only making 250+hp on dyno!

[vanisvandal]

It is also pretty hot in Vietnam huh? Maybe heat soaked a bit to top it off. How long was the truck running Before dyno? I know mine was giving me trouble with a 93 octane that truck didn’t like the additives. I hear these motors are a little picky to get optimum performance

I drove for just less than 5 minutes before the 2nd dyno so I believe heat is not really an issue.

Way too many factors especially with these two types of dynos. Mustang and mainline dynos are load based. The weight,tire size,gear used to make run in must all be right or the numbers will be all over the place. Maybe find a dynojet and someone that has dynoed trucks before.

They did dyno many trucks (mainly Rangers, including Ranger Raptor) and the results are within the expectation. Therefore, I believe it is really something to do with my truck specifically, or the F150 In general.

You said they just got the mustang dyno last month. Is this their first mustang dyno? Unless your truck feels really slow its dyno operator error.

Off topic... you must paid over $200K for the Raptor in VN?

Agree with the 0-60. At 7.4 sec, there is something wrong particularly with 91 octane. I get 6.2 or less sec on 87 octane and better than 6 sec wit 91. I think your 0-60 confirms what the dyno is suggesting.

AF doesn't look too crazy, would be nice to have boost for the run. Will these trucks show boost in the digital dash? If so what's peak boost?

I dont know if the Ford dealer would bother to dig into it or not, if not maybe get a data logging solution (ie bluetooth obd2 dongle and a cell phone app) and find a member familiar with the basics to email the log to. Then you could check commanded timing vs actual, if its showing any timing reduction due to knock etc...

I know the mustang guys have had issues with pulled timing from false knock due to vibrations from aftermarket exhaust etc...

There is a tsb on an issue with power. If you get a misfire and have louder than normal exhaust sound. They replace they muffler as some are bad.

Yes, around $210k after taxes and registration.

I do think that I should log data to see whether there are any issues. Thanks for your suggestion.
I do have Ford Performance (Borla) Sport on my Raptor but the car did 0-60 in 7.x seconds both before and after having the exhaust.
