infiniti g37 dyno update
hi everyone, i just want to share our project g37 allmotor and the updates in it because we decide to use hptuner and not osiris
first we put the car in the dyno a few weeks ago and with just exhaust we get in 3rd gear 267hp and with the reflash we get 279hp with 93 shell gas, and in 4th gear we get 292hp (the car is auto transmission) COMPLETE stock engine just reflash and exhaust NO headers.
THEN we put a g35 hr plastic plenum "better" ported and ported the aluminum middle intake manifold, we put 650cc injector clinic injectors and a walbro fuel pump to run e85 and new spark plugs (another brand)
i get some tips from hptuners guy
now this is the new dyno numbers and issues
FIRST the car i put the latency of the injectors in the program and the car start up right away but when i do a WOT in neutral the car make like a missfire and i play a little with the program and found the fuel flow rate and move here and there and the car work perfect with 650cc injectors and e85,
now time for go to the dyno...
we put the car in the dyno and make the first pass the car have 263hp with perfect AFR... so the car lose 16 hp in 3rd gear.... how can be possible with e85 plus all the other changes.... well something the car doesnt like it...
now its time to play with HPTUNERS, with perfect AFR in wot i decide to put more to see if the car need more but no changes in horsepower so next step
play with timing, vvl and vvt,
this time move some numbers and i get 20hp increase just moving those things...
so from 263hp that day we get 283hp in 3rd gear and 296hp in 4th gear...
now we order bigger aluminum intakes, the stock oem sparkplugs and we are going to put vq35de throttles (biggers) to see what we get
stay "TUNED"
