The Coupe world is a small one and despite me trying to be all stealthy, some eagle-eyed people still noticed that I'd been selling off a few bits from my car and worked out was up to something. Well here's what I've been up to!
Just over 400 bhp (or just under depending on which graph you want to use, I don't care, there both good!) plus over 385 lbsft torque; a manly wodge of torque at a useable 5000-odd rpm - and all at a "measly" 1.5 bar!!
Oh and now running a 3 bar MAP sensor, for those who are interested.
I'm now running a Turbonetics T3/T04E 50-trim (old 44-trim T04E hybrid gone to a new home). Plus some other minor changes, but the main part responsible for these results is what I've been banging on about for ages to anyone who'll listen:
Cam selection and cam timing. You can bolt on the biggest, most expensive turbo and wind up the boost. But if the valves aren't opening at the right time its all wasted. After all, what is boost? It's just the air pressure measured inside the inlet manifold. It's what gets into the cylinders that counts.
This is the cam setup I'm currently running:
InletFiat Tipo 16V 5-door inlet cam
exhaustFiat Coupe 16VT inlet cam - yeah that's right, the inlet cam!
cam PulleysVoodoo Tuning adjustable cam pulleys
Timed in with an eye towards strong, useable torque and power for fast-road driving.
Here's the full spec as it currently stands.
16VT
*Wossner forged 84.4mm pistons
*Forged conrods
*1.6mm MLS head gasket. Chosen for 8.0 CR and <1mm squish height
*Tipo 16V 5-door inlet cam, Coupe 16VT inlet cam (on exhaust)
*Voodoo Tuning adjustable cam pulleys
*uprated head bolts
*Tubular exhaust manifold
*Turbonetics T3/T04E 50-trim comp, st. 3 wheel, journal bearing
*Precision Turbo 39mm external wastegate
*screamer pipe
*3" downpipe custom-made (by me!)
*2.5" decat
*2.5" stainless mandel-bend exhaust system
*Siemens Deka 660cc fuel injectors
*Dual 255 lph fuel pumps
*8mm i'd fuel hose
*adjustable FPR @ 4 bar
*CG Motorsport 6-paddle clutch
*lightened + balanced flywheel, modified for extra clutch clamping force
*Weber Marelli 3 bar MAP sensor
*Stock Weber Marelli P8 ECU
So, is this currently the most powerful Coupe 16VT running the stock ECU?
I dunno and TBH don't care; it's very fast and I like it!
