Finally got my vortech kit installed and tuned. Pretty happy with the results, but wanted to see what those who have done this before would say when looking at the dyno graph. Critique away!

Car: 2004 G35 coupe 5AT

Mods:
V2 vortech tuner kit
3.12 pulley
Walbro 255 in-tank pump
DW 440cc injectors
MD 5/16 plenum spacer
Berk HFC's
Oil Pan Spacer
Transmission Cooler
One step cooler NGK platinum plugs.

EMU: SS box

Tuning was done over 9 pulls using a wideband (precat) to measure AFR.
AFR's on the graph are out of the pipe (look a point leaner than actual).

Dyno pulls were done in 50 degree (F) weather with about 80% humidity on a Dynojet.
Dyno graphs are smoothed but completely uncorrected.

 

Not bad considering you have a 5at. The torque to me looks better then other vortechs ive seen so congrats to that!

 

The torque curve is very pleasing. The car feels pretty normal up until 3K rpm and then just puts a smile on my face after that.

 

how much PSI? you running?

 

About 9psi at redline.

 

About 432BHP, that's pretty sweet.

 

This is on my wish list and really want this on my G. Those are some really awesome numbers you got there.

 

Looks good
Where did you go for tuning?

 

very nice numbers man! I bet its fun as hell driving now

 

Looks real good to me also.

 

With that much hp, how does it shift?

 

Your numbers look to be inline with your mods...maybe just a tad low. Discuss it with your tuner, but if the graph at the bottom is correct, you may want to richen up the AFR a little.

EDIT: zoomed in more, AFR looks fine

 

Thanks for all the comments guys.

I do think I am starting to run out of fuel above 6250 or so.

Shifting is pretty good. It does clunk a little when getting on it. I do see a transgo kit in my future.

Highway cruising is a blast. It feels smooth and downshifting is not really required for passing.

Way more fun to drive now.

My tuner works for Ishii Motor Industries in Bellevue. Small independant shop that gets it right all the time. They really don't have a web presence, but this link tells the story.

I can't say enough good things about Steve and Cameron. If you want a Vortech installed (or any other form of FI), these guys do a great job. They even put up with the quirky SS box I made them use.

 

I think the numbers are in line with your mods, I had a fuel return system added as I noticed my fuel started running lean towards the top end of the rpm. I think I hit close to 400rwhp with a few additional mods but it's been awhile since I had a Vortech.
