Change in exhaust 620lbs/ft
Discussion
So mods this time were LS9 supercharger injectors, H pipe, Independant ECU feed via relay to stabalise slight voltage drop at high revs, and Piper cross sock filters, and flip the ITB's 180 so adjustments are not up the bulkhead, i have put a wide band in too to aid setting up on the road...
Here is the Graph, what you cannot see is how smooth the car drives at street speeds, and throttle response is also much crisper, thanks to the new injectors i would say, its up on toerque and power all the way up to 550bhp, and up from around 580lbs/ft to around 620lbs/ft, so 40lbs or so up but down 16bhp at peak.
I think if i want more power i have to go bigger valves and exhaust, but this will mean losses in torque probably and cost around £3.5K, the car is rapid as is, and would only be a wallet busting/scientific experiment as grip is challenging as is!
The main thing is the low running glitch i have suffered this summer, is now sorted and its driving the best ever

I think we had a chat at Chatsworth this year you were telling me what you were hoping to achieve... I knew then you were ill You missed a great day at the pod Paul. The weather was perfect, only TVRs were allowed on track.
They had topless models as marshalls and everyone was given free champagne and all the chips you could eat.
Eveyone ran PB after PB and went home very happy.
Some of the above may have been made up

I have a trackday all booked and paid for on the 16th at Silverstone, so i will be doing that, did not want to risk busting something.They had topless models as marshalls and everyone was given free champagne and all the chips you could eat.

Next year i will raise the bar with a 10.4x, no joke..

I put a H pipe in the exhaust and it dropped from 581 bhp to 565bhp, but torque is up from sub 600lbs, to 620lbs ft, drove it home tonight, and it's got some grunt.. the open ITB's sound glorious, will post Dyno later.
Pah, mine made 630 the open ITB's sound glorious, will post Dyno later....but I do lust after the throttle bodies.
