Re: Spec V, first build, about $1000
Ok I finally went to the dyno so any time you want to set up a run between me and your friends with the NA Spec V's, I've got $500 on me to win.
these were the first two runs at 6psi so the motor was fairly cool, the best numbers I've ever seen for this car at such low boost
the next two runs I did were at 9-9.5 psi, I added some fuel after the first pull to get it under 12:1
.....so after adding fuel to run 9-9.5 psi I did this pull at 7.5-8 and the AFR's were rich, around 11ish
so after pulling a little fuel between runs I ended up with this graph and a better AFR, but at this point, after 7 pulls, I'm sure heat soak was taking it's toll even though the numbers were better.
It's suprising what the diffrence between 6psi and 10psi feels like for only being 33 whp and 32 WTQ. The diffrence between 0 psi and 10 psi is very nice

A great idea would be an Altima SE-R engine in Sentra SE-R + turbo ftw

drop in a vq40de from a frontier and have 270hp/285 ft lbs no problem, and bolts in place of a vq35 from an altima 3.5
