It looks like B-Lo has the fastest VXR so far and without the reflash even, those are good numbers. Anyone know what the rev limiter is on the stock ECU?

[Aquaholic6801]

According to my aftermarket tach the soft limiter starts kicking in at 7680... and hard limiter at 7700....but seems some folks got skis that have a higher rev limiter.....

Oh I have the R3 reflash oops did I not put that in there. Sorry.

The R&D one?

[B-Lo]

The R&D one?

Yeah

[Jarrett]

Cool, got it updated. I guess Jerry will ultimately have the fastest one, but for now B-Lo is da man!

This is for my VXR in it's naturally aspirated state

Speed @ RPM: 72.1 @8360 RPM
Year/Model: 2011
Name/Weight: Jerry Gaddis 240 lbs
Air Temp: 75 degrees at time of run
Altitude: sea level
Fuel Level: 3/4 tank
Mods: All modifications installed on my ski are listed below:

The Riva Power Filter
The Riva intake manifold upgrade
The Riva rear exhaust kit
The Riva pro series waterbox
PWC Performance Ride Plate Inserts
R&D grate
Skat 12/19
Jim's Performance VX ride plate modification



In bone stock condition my VXR ran 66.6 mph on GPS
With the Riva power filter, intake manifold upgrade, Riva water box and rear exhaust kit the ski ran 69.0 mph
I added the Jim's modified VXR ride plate to the other modifications and the ski ran 70.1 mph

With the V-Tech VXR tuning the ski ran 72+ mph on GPS with huge gains in acceleration as well.

I'll get some final numbers for you guys in it's turbocharged state a bit later. Just some fine tuning left to do.

Acceleration graphs and more details about my VXR when it was still naturally aspirated can be seen here
