Just got back from the dyno, heres the plots.. 10psi Gt15 turbo. one is with 20 degree advance, the other 24 degrees. 109 nanas and 115 curly whirlys, was pleased with the torque curve --- full curlywhirlies at 3.2k and flat to about 5k.

you can add about 26 bhp for a heli and around 22 for a straight cut tel ,also if there was not enough air flowing thruogh your intercooler itll run richer than it would on the street .
Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

It has SC drops standard box 8.5 CR 1298cc standard turbo head 14cc accralites and Kent 266 cam plus 2.95 Diff. 130 odd is fine by me!. As you can see the torque is all there at the low end and when driving it thats what I feel. On the road I rarely rev it over 5500 ---no need. Still say that for a road car the GT15 is a cracker, but having said that it probably would run out of steam at 14psi. website:- http://www.terryhunt.co.uk

Hi, With only 10psi and 8.5 CR I'd say you could run more advance than that, or up the boost 
Cheers, Gavin :) Due to recent history I got No balls Gavin!! I want that needle perfect then I'll try 26-28? what do you think? It raised 3 nanas per 2 degrees on the 2 steps I made so 115 nanas may be possible. This Dyno is only a few miles away and they strapped it in and got it running pretty quickly. I'll use it again but just take a few pulls next time which is cheaper. Plus now I know my O2 is accurate If only I could datalog my O2.. maybe the next Megajolt version will solve that one..

having said that i am not sure what your goal is ?????????? 
The ports, valves and guide bosses is your governor This need to be addressed , are you running an intercooler...?? I am after a road car so didn't get into that stuff aside from porting it a little. I have a side mount intercooler, again probably less than optimal but does the job better than most would suspect. Not really interested in BIG nanas just drivability and it feels fine on that front so I think I have what I aimed for. website:- http://www.terryhunt.co.uk
