I just made 533rwhp!

Well guys, I had to do it...

In search of more power than what my AA kit could offer me, I had to make the switch to VF. Hanging around Drew and having him pull on me so hard and seeing him hang with the big boys was driving me crazy. So.... if you can't beat 'em, join em!

I dropped of my car with Nik and the guys over at VF-Engineering last week for their stage 2.5 kit which uses the monster T-Trim blower. Hanging around VF, I have to say, Nik, Delius, Sean, Mike, Jeremy and all the other guys at VF are amazing guys. Such nice really that really enjoy and care for what they do. They aren't in it just for the money, this is their passion! I seriously feel as though I'm part of a family now.

After picking up the car, I immediately noticed the deeper, throatier exhaust note, which I didn't expect. The car sounds even more wicked now!

Leaving VF and without even getting on the throttle much, I could feel the extra power and torque. Not only is there more power up top, but there is more power all across the power band. In fact, I find myself switching up gears at a lower RPM than before due to extra low end power. On the way home, I literally had to make sure at least three separate times that I was in fact in 6th gear and not 5th! The car was pulling harder even at a low RPM in 6th gear!

The car pulls SO freakin hard now; it feels like it has endless power! Just pulls and pulls and is finally giving me that feeling of being hard pressed into the seat. I'm now losing traction even in all of 3rd gear.

What impressed me the most was the shifts and how smooth they were now. Unfortunately with the AA kit, there is a little lag/bog between shifts, even after doing the shift lag mods. I can now shift as fast as stock. I think the problem is that the AA blow off valve is too small for the amount of boost, which causes some pressure against the throttle bodies during shifts. This is the reason my shifts were so slow in my past Vbox runs. The car now funs perfect and smooth, the software seems spot on, and the AFR's are in the mid 11's.

When I first saw that video from VF with them touching the intake manifold after some hard runs and them saying, "it's cool to the touch", I totally thought that was bogus. But after driving the car hard, I popped the hood and the intake manifold after the fins was seriously cool to the touch, I was very impressed. Driving around in the heat the past few days has proven that the air to water system works GREAT! My car used to feel bogged down in the heat with the AA kit, but the VF kit seems much less affected. The oil and coolant temps appear to be the same with both kits. I do have to saw, I do miss the look of my front mount .

Now for the good stuff.... Dynos!

Unfortunately we couldn't get a perfect RPM signal. It would cut out at around 7,500 RPM (could be due to my nitrous' TPS install). So, all dyno plots are shown with speed vs. RPM. Also, as in every other AFR tail sniffer I've dealt with, the AFR's were not coming in clear... I did however record a couple AFR runs with my own Innovative AFR gauge tonight, and those all look great with AFR's at around 11.5 all the way across. I will upload this later for you guys.

Here is a crappy cell phone pic of the direct port meth setup we did:


Dyno # 1: 91 Octane, no meth, about 65 degree ambient

Dyno # 2: 91 Octane, no meth, about 100 degrees ambient!

Dyno # 3: MS109 Race Gas (105 motor octane), no meth, 95 degree ambient!

Dyno # 4: Dyno plots #2 and 3 overlayed.


I'm very confident the car will do at least 550rwhp on race fuel on a not so hot day

Here is a dyno of the AA kit vs. VF kit. Both on 91 octane, no meth



Rotrex vs. T-Trim:

OMG hell yeah!

Your car so deserved this! F-ing Game Over!

Oh yeah and you haven't even used the meth yet! When will you tune for the meth injection?

You will be able to change the pulley/belt for more psi.

Congrats, hope you are happy with your decision!!!

Look at that size difference, i am still proud of the rotrex. Making 503rwhp (9.5psi with a slipping belt) 3 years ago with AA's kit, hot weather with 100 oct from the gas station, i have no reason to believe there should'nt have been a difference you felt like this.

Get that meth on, i dont know if i trust 11.5 psi on pump with no meth.

Vik,

I was very happy for wit my AA kit for nearly 2 years. But I needed more power than it could give me.

I REALLY don't want this to turn into a AA vs. VF thread. That is not my intent AT ALL. I'm just posting my experiences, opinions and what I truely feel as an enthusiast.

I agree about the meth, I don't feel comfy running this without it for too long. But hey, the car has taken it so far. We did at least 20 dyno runs today and it ran like a champ and the correction factors were fine, even in 100 degree weather!
