Right, having been hung up on going with the TB's and boosted, I decided to crunch a few numbers as the primary thing that worried me was the low speed and TPS driveability.

Calculating the TB's throttle plate area and then the throttle plate area of the GMC 55m throttle body, I worked it the TB's to be around 130% larger than the 55m throttle body area - this would have a pretty violent affect on the low TPS angles. Jenvey don't really do any sub 40mm DCOE Bodies that I could simply swap mine for.

As soon as I saw this difference I knew that it would have been a bit of a pig to drive slowly.

What confirmed my choice to ditch the TB's was reading the whole of Sybez's Supercharged TB build - I could see that he'd had problem with the people that'd worked on the car before, but even after GMC sorting it all out, he still ultimately wanted to go back to a standard inlet which just shows about the driveability thing (he had 42mm TB's just like me)

To put the cherry ontop of ditching the TB's, I got the 1 piece plenum through and it was huge, and I think would have required a lot of work to fit so that will be sold on and I'll be going with ...................

as expected really, a C2 vts inlet, 55mm GMC throttle setup. I've already bought a c2 vts inlet, so just waiting on that to come. The same person I'm buying the inlet from, does have some other boosted parts for sale I'm hopefully going to be buying. plus fingers crossed Maxwell sells his Rotrex unit so I can buy his bracket and some parts off him.

As a result, this is my Boost Spec as it stands today, but little bits may change:

Engine
As Above in NA Spec BUT
79mm Wossner Forged Pistons and Rods
Jp4 Head
Porting done myself
Inlet and Exhaust matching done by myself
Piper BP285 Cams
Engine full rebuild
Constella Baffled Sump
Rotrex C30/94 Charger
C2 VTS inlet
ATPower 55mm Throttle Body
690cc Injectors (TBC)
3" Boost Piping
Big intercooler, maybe end up being custom
Alloy radiator

Be4r Gearbox
Gripper Diff (ramp angles TBC)
ATSpeed Gearbox Mounts
Hydraulic Clutch Setup (not 100% - might end up going cable)
OEM Flywheel
Helix Paddle Clutch

Predator Ecu
2.5Bar internal MAP Sensor
Mapping to be confirmed (not sure which company yet-no rush tbh)

Swirl Pot setup
External Fuel pump -> engine

Suspension
As above - NA Spec for now.

Brakes
As above - NA Spec for now.
Carbonne Lorraine Rc5+ Pads for the front
And maybe a rear disc conversion (not 100% yet)

Interior
A very lightweight bucket for the passenger
TRS 4 Point 3" Harness for the passenger
SPA Dash fitted
Streamline Dash surround
A few more items stripped out
A Nice rollcage - spec tbc

Non-Sunroof Skin

That's my ideal spec for now - engine will be done first before sorting the rest. I plan on putting the dash in with the engine so that the dash corresponds to the engine mileage (as they will both start at ZERO miles)
