I'd like to think my software is a little more accurate than that.

Whats the drag co-efficient of a sprint shell then? I will plug it in an see what difference it makes?

So only for discussions sake, say mine has the 107, does it in 15.5 secs. Then you take a conservative 1/2 sec off fro the LSD, makes it 15 another second because yours is miles lighter than mine makes 14, again 1/2 a second because it also has much smaller frontal area (drag) 13.5 sec's. Again 1/2 a second for your super sticky tyres and the better track. Where down to 13 sec's with 107 bananas.... Interesting. Of course all the above figures are just estimations a bit like that software, but makes you think.....


Are you smoking something illegal?

2 tenths for LSD, 1sec for weight, 2-3 tenths for Sprint shell (back to back tested on John Hastons sprint before and after conversion), what super sticky tyres?

I dont believe even in my car your engine would do low 14s let alone 13.0.

Dont forget Ive been developing this engine with Swiftune for 11 years. It certainly is no ordinary 1380. I quote Pete Baldwin, remember how long he's been at the game, "Ive never seen a 1380 show power like that before!" But remember also, its not how much power it produces, its how it delivers that power.
Prime example. There are many many 200bhp turbos that are pretty lightweight that are a full second or more off my times, 7 ports, 16valvers with lots more power but much much slower.
