Guys - I need some help!
I'm finishing my Rf40 this year which will be first registered with a standard engine, then used for a few years as a race-only car for road circuits with a second purpose built race engine. I don't know exactly what components the race engine should have to be right for my car and the type of racing I'll be doing, so I need some input that I'm heading in the right direction.
I will be probably using a new ZF 5 speed, 8 barrel fuel injection, and Motec. It needs to run on 98 Octane premium unleaded.
The engine needs to make not much more than 500HP, maybe low 400's torque, and make power to around 7500RPM? Probably an aluminium block if these are reliable?
I've already asked one of the bigger race engine builders for an engine to suit and this is what they came up with.
Basic Engine 347 ci Fully Machined Dart Aluminum Block, Scat 4340 forged Crankshaft, Scat H-Beam Rods, 10:1 JE Pistons, Plasma Moly Rings, Federal Mogul Bearings, Double Roller Timing Set, Front Cover, Melling Oil Pump, Oil Pump Drive, Oil Filter Insert, Timing Pointer, BHJ SFI Approved Damper, ARP Fasteners, Fel Pro Gaskets, Balanced, Blueprinted & Assembled
Camshaft Comp Cams Solid Roller 252/262 duration, .576 lift
Cylinder Heads AFR 185’s (All CNC work done in house)
Valve Train Scorpion Roller Rockers, Comp Cams Pushrods, Crower Solid Roller Lifters
Oil Pan Aviaid or Armando Aluminum
Dyno Test The engine will be dyno tested & tuned. We will provide test results.
I think this engine is too much HP and torque suit my purpose. I did specify around 500Hp and not monster torque, but when I rang them about this engines performance, they said she'll make 630HP at 6200RPM and 600 torque!
Can anyone recommend an engine builder who does excellent work with race engines and who can design an engine to suit a specific purpose and car? And who'll bother listening to their client?
Thanks for your input!
