VQ35 Swap+ New Mods= 241WHP 237WTQ
Last Dyno (same location and same corrections) --> http://i32.photobucket.com/albums/d4...yno4-7-07a.jpg
Great news NMexMax... I have the runfiles!!!!! LOL
New Mods since the last dyno...
- Jimes "T-stat staying open" Mod- while cruising on a hot day with AC on, engine stays at about 165*F, instead of the previous (stock) 192-195*F. Motor never feels heat-soaked anymore, always super responsive.
- 3" MAF- (didnt really add power, but it did help to HOLD my power longer towards redline. Notice the previous dyno had ~210whp at redline, now Im holding 220whp) |

very nice. Man this motor has a lot of potential on the top end!
going to PM you about that T-stat staying open mod.... very interested in that.
What happened at 5K? you got kind of rich there? Is that wideband's reading? or a tail sniffer?
I forgot are you tuning with a VAF2?

lol. The dip looks severe on the graph but if you look at it, its only a drop from 14.0 to 13.5, still within that good range. I do that on purpose, like to keep it a tad bit richer up top (preference). Also, this was a sniffer wideband, and from my experience with this shop, it reads lean by ~.4. So If you see 14.0, its really more like 13.6:1. And I use an SAFC1.
No need for PM, Jime himself had it on a post, I just cant find it. Check it. Remove your water outlet. Notice the plunger from the T-stat goes into a hole at the side of the water outlet neck (you have to have it in your hand to know what Im talkin about). Now seperate the Tstat from the housing (careful it doesnt fly off and catch your eye). Now's when it gets cool, get a drill bit or something, cut it to a length of about ~1/8". smouth out the cut so its nice and flat. Now, insert THAT into the hole on the water oulet, re-isntall the T-stat making sure that the plunger's rod sits level pushing against that part you just added. Once the Tstat is on tight, make sure the plunger isnt at an angle and has no play. If its good, put it back on, enjoy ~20-30*F cooler running motor :-D. Add some water wetter while you're at it. Cheap insurance.

As per our convo (jsut thought I'd also put it here for the other folks)
well lack of VCT is one thing, crappy 24* ign timin at redline is another, and probably the stock headers on wsp ypipe are starting to show their limits. probably just a combination of everything

Psssst. Headers have been shipped. Details on that will come in a week or two when I actually install them :-D. They are Altima 3.5 headers. So the ypipe wont fit, but the headers themselves should. Im hoping that I could salvage the loop for the rear manifold so I could keep them equal length. As far as the headers themselves, they seem to be a exact knock off from the new OBX headers for us. Plus they were only 1/2 the price of what the OBX headers go for, so cant complain at all  |

You're auto right?
Are those IGN numbers total timing (ie rather than adjustments?) If so you can add quite a bit more yet, especially if your coolant temps are under control.

Oh, to add one quick thing, as an alternative to the modified t-stat........
A 350z t-stat from nissan is DIRT cheap, they also make a nismo one for the 350Z that is even cooler, either can be used on the vq35 fwd by simply using a 4th gen lower rad hose (on 4.5 & 5.5 gens), either of these t-stats will drop your temps quite a bit from the fwd t-stat but still have the benefit of allowing your engine to reach operating temp faster and reduce internal wear as oposed to modifying the t-stat to stay open.

He's from the "Headers don't do anything" school of thought so it's pretty safe to say he's being serious.
