I have a non believer friend that thinks 429 wHP is unachievable from a maxima at 12.5 psi. Does anyone have a dyno sheet or something that proves it?

Turbo97se: I saw this in your sig. Is this true? No other mods besides boost? No engine work? Would you happen to have a dyno sheet?

Thanks!

 

429 was corrected whp

 

umm... don't mean to sound like a total n00b, but what does corrected hp mean?

 

We are at 5000+ ft. elevation, so there is a factor that they multiply the hp by to get it to what it would be at sea level. It works great for NA cars but there is a big debate about turbo cars. Some think that nigels numbers are inflated.
His uncorrected numbers weren't bad at all though. We'll have to wait for him to post.

 

from what i saw from his dyno sheet uncorrected number should be around 360whp which is still awesome

 

Yes, this has been a much debated issue. If you can find the old thread, you will see a lot of discussion around it. Frankly speaking, there isn't really a good standard out there that you can follow unless you use uncorrected numbers and no one really uses those. Even if you pick a standard that every one could agree too, there will always be non-believers and people will find other excuses like your dyno is wrong or the dynojet is not accurate blah blah blah, it's always something you have to contend with.

The car is fast enough for me ... a little laggy but it's OK. Now my only problem is staying in the country long enough to get my clutch fixed and the new GT turbo that has been sitting around collecting dust installed!

Last point .. I fully agree that the SAE corrected numbers for a turbo car at altitude will show inflated numbers. If you put in a compensation factor of around 10% less than SAE corrected, then you would get more accurate "corrected" numbers. SAE is really the only commonly accepted standard in the United States, there are some variations of SAE such as STD corrected which yield even higher results (about 4% higher) Until someone comes up with a better, commonly accepted standard, that's the one I will continue to use. It is interesting that this point only really came up when I started posting my numbers when I think just about everyone on the board uses SAE corrected numbers including superchargers. ... I am not going to turn this thread into a flaming thread so ... peace to all!

 

Good call.
