Absolutely. The MFG limiter is set at 160 mph. You cannot eliminate it, but rather have to use Uprev and program a bigger value. I set mine at 230 mph so in actuality, there is no speed limitation in this case.

Oh man.... No way to hit 230 mph. Even if you have the monster horsepower of 1000whp, you will run out of gear unless you raise the engine rpm to 9000 +, which is not possible for the VQ37VHR configuration !!! Maybe with a Vette Z06 or ZR1 gear ratio and rear end... then you might be able to.

Slight mods like my 370Z ( estimated about 295 whp I think... ). Full tank of gas. I weight about 165 lbs. Got up to ~160 mph around 6000+ rpm on 6th gear. Car could struggle another few miles but fuel got cut out. Took a while to get to 160 mph as I expected with the kind of whp that I have.

After Uprrev speed limitation was eliminated, I tried again and result was : ~ 163 -164 mph... A little less than 165 mph for sure. I wish I had a camera mounted but I could not do so... May be next time after FI. I did not want to have another friend sitting with me taking video because driving at that speed + watching for cops was very intensive and dangerous. Also, he weights 185 lbs and I can loose a good 5mph+ top speed.

If anyone ever truly tried to top end their cars , please post the data. I love to collect high speed data from different members here in the370Z.com forum !!

You should call Uprev and ask Jared. It is hard for me to explain though here since I don't have my car with me. If I did, I could just run out there and open up the GUI and let u know..
