Right guys, I thought it would probably be best to start up a new progress thread seeing as the TB build has come to an end :ponder: and the car is taking a turn into the world of boost now.
This is the car as it currently stands: ![]() ![]() ![]() ![]() ![]() ![]() ![]() The Spec of it is as it stands today: Engine 1.6 16v 106 Gti Engine Piper BP285 Camshafts OEM Catcam Followers Jp4 Camshaft covers Oil catch tank for the JP4 cover breathers Mocal Oil Cooler with Thermostatic Plate OEM Citroen Oil Filter Silkolene Pro S 5w40 Oil Twin fan setup (only one wired in for now) Peugeot Sport Group N Engine Mounts Predator Ecu Innovate LC-1 Wideband Sandy Brown Inlet Jenvey TH DCOE Bodies - 42mm TH Bodies Tapered to fit 45mm Trumpets by Colin Satchel 60mm Trumpets Custom Throttle Cable Retainer Jenvey Fuel Rail Weber Alpha External FPR Housing 3.0Bar FPR Jenvey Stepped Backplate and Sausage Filter Cut Scuttle to suit Piper 4-1 Stainless Manifold 'BTB' 2.5" MAnifold back Exhaust System Jp Custom 2.5" Decat Section Fuel Return line plumbed in Rewrapped Engine loom Gearbox S2 Rallye Gearbox Helix Aluminium Flywheel Suspension Biltstein Group N Shocks All Round GMC 40mm Front Springs (rumoured 160/170lb x 250mm) Rear lowered to suit Peugeot Sport 21mm Rear Torsion Bars Peugeot 24mm Rear ARB Powerflex Rear Beam mounts Powerflex Front Wishbone Mounts Powerflex Front ARB Mounts Brakes Hi Spec Billet 4 Front Calipers Maxtorq Group N GTI-6 Front Discs Volvo OEM Pads Exact Front Braided hoses 23mm Master Cylinder Rear Drums - OEM Setup Oz Anthracite Superleggera 15" Alloys Front Toyo T1R's Rear Toyo T1S's Interior Mildly Stripped out Cobra Evolution S XL Drivers Seat Cobra Alloy Sidemounts Custom front subframe TRS 3" 4 Point Harness RMD Suede Steering whel Custom Carbon Fibre Centre So this is how the NA spec will end with this car. Come the summer various parts will be sold off to make way for parts that are better suited for a nice boosted spec. The car is booked in on a Rolling Road day on the 24th April, so I'll get to see what sort of figures she's putting out, before pulling here apart in the summer. These figures should hopefully help to sell a few of the key NA parts ;) *Dyno graph to go here once it's been done* |
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) |
Right, everyone likes pictures - here are some parts pictures I've accumulated already for the project:

got boost? ha love it mate as you allready know. oh and first passenger ride is mine people. even over his brother lol

Hopefully it'll be worth the wait. Just uploading a few more pics, and the hopeful spec of the car once it's done, plans etc. |
very organised build thread Ross lol
should be the mutts nuts when its done! ps. charger guy was a total time waster :( |
On the subject of throttle plate area, I imagine it will be similar with boost, but for N/A single inlets, I compare the area to two of the TB plates, because it's a closer approximation to assume two cylinders are breathing at once than four. On that principle and subtracting an approximation of the spindle/plate section, about 15% less area with the single inlet. I don't really see that being much of an issue, not one that careful mapping wouldn't resolve anyway.

Taking the area of 2 throttle plates instead of 4 changes the area different to a 55mm single Tb a lot !! it goes from 130% difference to 15% difference, which is sod all really tbh :S |

Very tasty plans ross
You running boost & boddies??? Your car needs a spoiler IMO (cf ;) looks lost with out one Get a few flocked things chucked in there as well |

I'm veering towards the C2 vts inlet as it's been done before, got some cracking results, and after reading sybez's progress thread I'm not sure I want to iron out the problems he had tbh. I've found a S1600 cf spoiler but not sure whether to take a punt on it as it'd need to be sent from abroad and would need a bit of work doing to it so that it could be mounted on a tailgate again - I think my money is best spent on going boost for now, the little exterior bits can come in the future :cool: |
It's up to you obviously and whatever whoever is going to map it thinks to be the best strategy, should be foremost in your mind. They'll want to be working on happy and familiar turf. With big boost behind any closed throttle plate, you're going to see dramatic changes in cylinder filling against throttle angle. The single inlet plenum probably acts as something of a pillow in this respect and having general MAP sensing will help with the precision of the air metering.

nice to see a new thread up mate, definatley best... Being though its getting a massive overhaul! Cant wait to see the build, BUT DONT STRIP IT BEFORE FCS! i want a run with you to see how it goes

She won't be on the track though, unless sax-p do a session for giggles |
"reserved for..."
"reserved for..." LoL. I feel like I've walked into a pub, looking for a place to sit down... Best of luck with this matey! :y: |

I've reserved them for like key moment of this build, so people can get all the info they want on the first page - I'll put more detailed pictures in the thread as it comes but the key ones go on the front page!! |
