GTO-3R on a dyno

Howdy all.
Long time prowler, first time poster.
Found a vid you might find interesting

Horsepowerhouse are one of the US installers. They have some power adding options on their site as well.
I know nothing more about them, I just stumbled accross this in my search for all things noble.

What is the engine spec? is it an M400?
Spec is:
Larger Intercooler
Solid Boost Pipes
Tial Dump Valve
ECU Re-Map
Different Exhaust (no cats AFAIK)
The power has come from the ECU and the ability to hold said power from the larger intercooler. However it seems the HPH Nobles have forged rods/pistons as standard, although British spec cars should have no trouble reaching similar figures.
Last word from HPH was good but I've since heard (from sources other than HPH I should add) that they've gone into receivership

I never got a proper handle of what in UK spec engines. There were mags that said it had forged everything in the earlier reviews.
If you look at the boost curve of a standard 3, its pretty obvious theres a lot more power on tap if they didn't cut boost so very early (to give flat torque curve). Dunno whether the engine would really need forged parts for that or not. I did hear that the m400 mule didn't even have the forged bits although all the customer ones do? Given how hard a life that car had, and the engine held up, it seems fairly promising if someone wants more power.

3r doesn't have forged everything, M400 has forged pistons and I suspect some other internal work.
Interestingly the compression ratio of the 3r is 8.5:1 vs 8:1 on the 400, the bore/stroke for both the 3r and the 400 is the same at 89mm/79.5mm, whilst it would be possible to drop the compression ratio by using a pair of thicker head gaskets or similar its more likely (due to the change of pistons anyway) the piston shape differs between the 3r and 400.

I suspect whilst the 400 test bed didn't have forged items its internals different somewhat to the 3r engine , especially if the test bed also ran with an 8:1 C/R.
Its entirely possible to pull 375-400bhp out of the 3/3r and 460 - 500bhp out of the 400 whilst maintaining reliability.

For the US model, the engines are identical. You don't even tell AER what car its going in, merely that you want a Noble engine.

Sorry should have made it clear I was discussing the GB spec engines. As you correctly state AER have a single spec which I believe has the forged rods/pistons?
