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.

- 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.

That picture is very alarming for use cobra owners , Two roll bars would be better ,I didn't buy my car to be safe and one roll bar it will be for me . The windshield posts on these cars look to be very weak and not safe in a rollover . I know there have been several survivors of rollovers ...........But this whole thing is a Gordian Knot of alpha male opinions ..........I am more worried about getting hit from the rear and snapping my neck. 
But I can't help grin at Patrick's beautiful ride with two bars and padding on both no less  .I was a believer how fast and deadly these cars can be after I actually drove mine.
I would like to know exactly what happened to the poor chap laying deceased on the pavement....was it the car ? was it driver error ? Or was it just an accident with a car that is known to be a killer sometimes ? Or when your number comes up are you just going anyways ? ..........At my age ONE rollbar is what I want ,that is my choice . Short wheel base and lightning quick ..........makes me feel alive too . Respect this car ! IMO. Patrick I will
give you a hundred bucks to take that padding off them bars for one year ! :-)....all in fun sir and drive'm if you gottm'.....no bars or multiple fine by me . And even padding too
One thing I have really considered is high back seats for better safety ......I still say these cars are safer than a motorcycle . be safe guys
