VQ37VHR + Mods + 150shot = 450whp

corbin09 · 03-01-2010, 11:14 PM

I have a question, excuse me bumping kind of an old thread, and my lack of knowledge in this field, but do you have to tune for nitrous or just use more fuel/ different plugs? IF you do, what did you use to tune it? if you dont, wht kind of plugs/ fuel upgrades did you use? Also, would you be able to use a kit that was designed for a 350z hr? or do you need a different one? THnks!

Its not a MUST to tune but its good for the longevity of your motor. Nitrous kits are mostly universal in the sense that all the solinoids are pretty much the same...

The only thing you change for the shot size is the pill which is located in the sprayer you put into your intakes.... im sure you could use the HR kit as both have dual intakes and you would need 4 solinoids to do the job.... 2 fuel and 2 nitrous.

As far as tuning, its great to know what your A/F is so you can adjust to make sure you arent leaning out mid run.... but if you want to do it the cheap way you could just run a wideband to get your A/F reading then either choose bigger or smaller fuel pills for the fuel shot you are mixing into the intakes with the Nitrous.

I wouldnt do 150 shot because then you are in the territory of small blocks that have more displacement and can spread the mixture around to more cylinders. I would actually not recommend going over 100... I had an 85 shot on my 350z and it was more then enough.....

In all honesty though, good job.

EDIT: wait....your stock baseline was 330? Thats crank hp ratings....and you say you are at 450 now? I hate to say it, but if 330 was your baseline whp....you are NOWHERE near 450WHP.... Maybe 350-360..

I say that because our cars dyno at around 240whp on a Mustangdyne dyno. If you dynoed in at 330whp stock thats like 90whp over the norm... 450-90= 360whp for a mustangdyne. What dyno did you use? A dynapack??

Why is this in the forced induction section again?

I am a ****.

Be a TT 370z but the 135 hasn't let me down at all. Trapped 120 with stock exhaust still in tact and is a more livable DD...
