Al427SBF Al have been involved with HP and torque since 73. You didn't say what company your car is coming from.
Problem #1 is the frame up to the power you are looking for???
Problem #2 is the drivetrain able to handle the boost power???
Problem #3 is the DRIVER smart enough to handle this KILLER???
Has the driver EVER drivin a car with manual and basic everything like brakes, steering, maybe 15" wheels and tires with 500HP and or torque???
Odds are your reflexes are too slow to react to problem happening, mine are.
I have tryed the same thing with my car. A 452 Shelby motor with a Novi blower. I built my car with an FI system from F.A.S.T. Car comes on boost and WOW. 6 pounds hits like a tank. Rear tires go up in smoke or car start dancing across the street. This is on concrete and tar. The car needs traction control and a steering slow down responce.
Build a motor with 600ft of torque. Drivability is alot better, motor lives alot longer, have more fun, parts are not being pushed to the limits.
Blowers and turbos are both hard on bottom ends, blowers a little less under boost conditions. Pistons tops need to be coated and skirts need protective anti scuff to protect cylinder walls. Need a motor with a large bore and SHORT stroke. Heat coming from this motor is big. Largest radiator you can find. You said nothing about after coolers?? Air to air? Water to air? Water injection?? For turbos extra oiling cooler, Mobil 1
oil at $8.00 per quart.
I have gone to a 482 stoker motor with 600 ft of torque and 560 HP. This is a safe limit to what the car can handle for an average driver. Car is still a handful but more forgiven. Boost cars are not as quick to reply along the same lines. Banging of turbos or blowers happens, even with boost control valves. Talk to Cobra #3170. Bruce has a 800HP motor in his car and about 1/4 million dollars of R&D. It's streetable. Excaliper tryed the same thing with 650HP and if you look at the old threads he went back to a street motor got double the mpgs, more streetable, less breakage, less maintainance and happier to drive all the time.
IMO as far as the Shebly twin blower car, I don't believe some of the info. Those ball bearing blowers max out at 7-9 psi of boost. Slippage happens. Same for the 1 belt that drives both blowers, belts slip. This car is also a automatic trans car, Torque convertor slipping to at high rpms. Super heat coming from motor under the hood. Little air screens to the blower to keep dirt out. The BIG thing, I have the same hood for my car, at 138mph the car starts to lift in the front end. I am guessing at 145-150 you can become an airplane and get takeoff clearance. My car is 2705 with out my weight. A shelby is lighter by 200-400 pounds maybe more. I have thought about the 200 mph club, I can build the power, major problem is keeping car on the ground WITHOUT any extra down force help, Just like Dick Smith did.
Build what you want, I hope your brain is smarter than your balls with this. Hope Lovehammer sends flowers. Think he has been watching his avatar to long. Try Flow bench here on CC. He has and builds turbo and blower cars for speed records. FE motors too.
He has a motor(FE) in the 2,000 hp range. Put this in a street cobra and see what happens
