and it weighs 110lbs less, with bigger tires, better suspension and more downforce! Woohoo!

I wonder if Loren has numbers from the street GT3 cars in that same dyno, to have an idea of the power gains in your car compared to the street cars.

I would expect the 2008 GT3 Cup with a 3.6 to have less torque than your 3.8.

Recently a Nissan GT-R and a BMW M3 V8 were tested on a Dynapack here in California. The Nissan came at 452 HP and the M3 at 370.7 Hp.

So Garrett, tell me again, what does your 422/303 mean relative to flywheel HP according to Loren?
Scary beast, Dude!
Do people know its name?

Hi John,

Loren said a 10 - 15 HP loss is typical for the Cups or output in this range. Nah, "Carmine" will be a gentle beast, graceful and swift. I doubt the name means anything to anyone outside of our small group but its name is "Carmine". I'll explain for everyone’s benefit.

Johninrsf is the POC GT2 champion and he is responsible for my kids not being able to attend a private university. After this project, community college will have to do. I have been building this car for over a year with one goal in mind, to beat John. John's car is called the "Killer Bee" so I named mine "Carmine" after the African bird "Carmine the Bee Eater". We plan on chewing up some Bee at Laguna. John's days of winning every event are soon to be over.
