No-one will ever see my map. It's not so much that its a cloak/dagger secret, but more that I wouldn't want anyone copying it, then blowing their engine up. I don't agree with all this publishing of maps for others to copy!!

With all this talk of 300bhp, I can tell you a few things.

When we first got our Dyno and I believed that I had 320bhp (this is 2-3 years ago), it had made roughly this power on another Dyno and broken the 160mph barrier, then I ran it on ours and realised I only had 280bhp. It was still a fucking quick car, no doubt, but not 300+ as I had thought.

Now it is 320bhp, its quick on another level, but I think most of that is down to the torque curve and the way it delivers power. The torque is almost totally flat. It has only 20lb/ft less torque at 7200rpm than it has when it first comes onto boost.

I'm not sure if it will stay like that as I correct the issues I have and raise the boost, but for now, its feel fucking ballistic.

As Crazycage said, I have done 120+ terminal speeds, can't remember how fast exactly as I have never been into 1/4 miles myself, although I am determined I am going to pull at least a semi-respectable time out of it soon. It has done 165mph in a mile and on the next outing, I hope to hit 170mph in a mile.

Jamsport do indeed say they can get 350bhp out of a 1600CVH, Stuart Collins car is the proof. I've not ever really seen any proper graphs from it, but its clearly quick and its clear that alot of effort has gone into that car, far more than a rebuild, big turbo and cam.
