Sneak peek at gutted plenum dyno results.

i guess i missed something?

being new to the z scene i have to hand it to you guys, as a community you seem to have a lot of time into research. i own a 86 maxima, a 84 n/a Z, and a 99 altima and for the most part most of the communities i've seen are full of hot air rather than straight facts and dyno charts. i want to personaly thank jason for his site and for the work he has put into this community

[G-E]

let's all say a prayer to the eternal Z, bow before his blood lust, respect his unrepentant nature

Welcome to the site and you are at the right place for the "real deal" when it comes to modifying you Z31. This board is full of guys with tons of knowledge and very little hot air. Oh btw, there are some "characters" here so there is some good light hearted stuff also. :wink:

Does anyone have a completely stock 'Nissan' dyno graph that can be compared to this? Either NA or turbo?

Scroll down for norcalZman's car, about as close to stock as I would have on there.

The gutted plenum, stock plenum and stock plenum with 60mm TB (in Jason's testing) all produce the same HP from 4000-5000 (roughly)?

I would expect the gutted plenum to actually shine in this RPM range. They (gutted plenums) do extend the RPM/HP range higher past 5000 RPM. They also seem to have a very nice torque benefit lower than 4000 RPM.

Is there corresponding AFR data also? boost level? MAF readings, etc?

Sorry, my LM1 has been broken for a while and I have not hadd the money to send it in to get fixed :-(

AFR is the usual high 11's for all areas in boost, which is stable at ~10.5PSI where I tested all the plenums.
