The boost is electronically adjustible in the cockpit. At 14 lbs boost it's approx 600 rwhp, this video from a few months ago was at 15 lbs boost.

I tried 17 lbs boost, but it kept spinning the tires on the freeway, took me out of my comfort zone, so I dialed it back down. Cheers.

That looks like fun! I wonder if the same power in a naturally aspirated engine would make it easier to control wheel spin, and get more power to the ground. Still, that looks like a blast! What was your speed/rpm/gear when it got squirrely on the freeway? I'm just trying to get a sense of what my car will be like, but I'm only planning on just over 500HP/TQ to the wheels, so I know it probably won't be too squirrely, but I worry about traction from the middle of third gear. Not really worried, but just want to be ready for when I throttle it up in 3rd gear and starts spinning the tires.

TXBLU, bear in mind I run 2.73 rearend gears (my car is set up for handling). When I dial my power down to around 500 rwhp, I have no wheel spin at all except 1st gear (on the street). At the track no wheel spin at all in 1st if the surface is prepped.

Sorry for the thread hi-jack you guys. Cheers.

Twin,
Please start a thread of your own about the content and experiences of your car. Not everyone's cup of tea but technically very interesting for the tech-minded like me. You can answer questions and you'll get plenty. You've taken a different path and it needs to be explored. Not the usual 'floor mat' thread...
Apologies to OP.

Looks like an apology does not count as much anymore...just kick them in the teeth to make a statement. oiy oiy






And NO, I'm not sorry to change subject.

- what got him?

fell out, banged head, bar not properly sized, G force - no emergency vehicle and no EMT

Terrible to go out making a mess on a public road.

Roll bar seems to have worked properly - helmet, and harness, a good chance he walks.
