dyno comparo

Well, I had my new G35c dyno'd at Reinhart Racing here in town using a Dynojet. They really tune Ford products ('stangs, Cobras, Marauders, Lincolns, etc), but they are a Vortech dealer.

Anyway, got two pulls in 4th, 2 in 3rd. The first two were interesting: car was at 210.0hp/259.5tq and 212.2hp/259.6tq. Whoa. Apparently, 4th is the wrong gear!!!

The good news was 3rd gear yielded 222.5hp/220.7tq and 223.9hp/224.0tq. This is about what I expected, though the tq is about 5 units higher than I thought.

For comparison purposes, this was done here in Jax. It's 65 degrees and the humidity is at 92%. My old car, a 2002 TL-S with intake, headers, chip, pulley ran a 233.7hp/196.7tq. This was done in Atlanta, and it was about 35 degrees outside with about 50% humidity (scalbert's help). That car also regularly ran 14.2xx-14.3xx at the track, though always had terrible traction problems--even with newer Cooper and Nitto tires.

My car is bone stock now, and has the 19's. I am going to take it to Orlando Speedworld and see what it does. I am expecting similar times since it hooks up rather well with little squat (sport suspension package).

That being said, it's got right at 1k miles and really isn't fully broken in. I have my Royal Purple synthetic sitting beside me, ordered a Motordyne plenum spacer and have ordered the JDM Infiniti CAI as we speak. I'll do those things in a couple of weeks and then dyno it again with about 2,500 miles on it to see what it sits at then. I am only going to add an exhaust in a couple months, then drive it to about 20k miles before going FI and selling the CAI to some lucky person.

hmmm. i thought the VQ in the G35 would be putting down more than that to the wheels. Was the dyno calibrated?

New SAE corrections (supposedly), 280hp/270tq from the factory. For an AT, that's 20% drivetrain loss...About right in line to be honest, and was simply interesting comparing the two cars...

I've been on this board a long time and have seen some of their posts. I find their results questionable. I used it in both my Acuras for over three years and over 70k miles on my modded TL-S. The place where I get it in town uses it exclusively on a myriad of modded cars and trucks for YEARS as well...

Thanks! Just an exhaust and sme sways. Then I'll probably wait a year and add FI.

I took a different job with a sgnificant pay cut and no bonus, however, I'm now at the top of the food-chain and run the show. I'll pad my resume for 2-3 more years before I can command significantly more $$$ in my market. We still travel every month or so and I really don't want to downgrade my life to mod my car. And besides, as a lesson to all the young ones, I buy NOTHING with credit, except a car (the depreciating money-pits that they are), and definitely am not using that for $7k in mods...

UR crank pulley
Stillen grounding kit
JDM/Nismo CAI (AEM really)

Welp, installed and dyno'd...
I'll post the map later tonight since 'big brother' here at work blocks photobucket...
Anyway, car hit 246.0hp and 222.5tq. That being said, the useable power has been TREMENDOUSLY AFFECTED. You will really have to see the graphs to fully tell, but here's a tease of what you will see:
car makes 200hp at 4650rpm (compared to 200hp at 5050 before)
car makes 225hp at 5500rpm (compared to 220hp at 5700 before)
car stays over 200tq until 6400rpm (compared to car above 198tq until 5700)
car stays over 210tq from dip at 3250 until 5800rpm (compared to falling below at 3000 and never getting back to it)
In all, the torque curve is extremely linear and fat and is often 15-20ft/lbs greater than stock. The hp gain is smoother and more linear for sure, and is a solid 7hp or so greater than stock until about 5700 when it really increases to its max of 22hp over stock.
My impressions from the seat of my pants? Well, the CAI and Motordyne were done at the same time, and honestly, I felt little if anything at all. However, I did just install the UR pulley and grounding kit, and I immediately felt a noticeable difference in the car. It just seems to climb more easily and freer into the powerband and I really feel the torque difference now. My friend drove my car—but only since ALL mods were done after having driven the stock car. Needless to say, he loves it and can’t believe the difference for only $1k in mods. .
My headers should be here any day. I'll get them installed and dyno again in the next 2 of 3 weeks after my trial…Maybe I’ll pop back down to OSW to see what times it’s now running.
For those who asked privately, and to explain these further, these were NOT SAE numbers. I got the original SAE numbers, but the chart is totally screwed up. The original SAE numbers were 216.8hp/217.1tq. The SAE numbers for this run are 238.5hp/215.7tq. The above comparo is done with uncorrected numbers only because the two graphs I have are for the uncorrected numbers. Either way, standard or SAE, the gains are relatively the same…
I hope to pick up 10hp/10tq from the headers, but we’ll see…I’m very pleased with the results so far and will keep you posted on more…

rofl...I had to get my wife to get these from .pdf to .jpg so I could get these up...




Now that you see these, and now I have had time to really look and think of them, what's everyone's opinion on my a/f? Any have VQ knowledge, here? Well over 13 with mods??? Seems awfully high to me...

I had some problems with my header install. A long, drawn out post was sent to me by a tech at Technosquare about resetting my ECU. Anyway, it worked!!!

I did reset my ECU and had the car redyno'd today. Granted it is cooler (55 degrees at dyno time), but the reset instructions really seemed to help by the butt dyno. I have now hit 255.6hp(245.8hp SAE corrected) and 235.6tq(229.8 tq (SAE corrected). Torque stays over 210tq until almost 6200 rpms...

I'll try and post the dyno plot later tonight. I appreciate the guys w/ Z's the pm'd me on my header issues!!!

Overall, I am pleased that it was only $2k to make almpt 30hp/15tq and more importantly, 35tq in useable gains over 2k-4500 rpms. Certainly beats the 233hp/196tq TL-S with all of the bolt-ons but exhaust. Now if I can beat the TL-S's (yup, with spare, gas and normally inflated tires) 14.237 1/4 mile, I'll be really happy...
