  1. Cobra Jet V2 intake on S650

    How did the power curves compare? The CJ pairs up better with aftermarket cams
  2. Waiting on pro charger

    Shouldn't be much different than the S550 C8 kit has the corvette tax
  3. What is your go-to place online to shop for your s650?

    Drop shippers don't keep all this stuff in stock
  4. Cobra Jet V2 intake on S650

    Is it worth it without aftermarket cams?
  5. Our S650 HP compared to the C8.

    Now compare the trans ratios in the C8 to the 10R80
  6. Our S650 HP compared to the C8.

    I understand that the 'math' is there but in the real world it doesn't really make a lick of difference. Go get a dyno sheet and prove it. Both engines have to have the same displacement, compression ratio, cams, and the same heads. Only difference can be bore/stroke. Going to make the same...
  7. Our S650 HP compared to the C8.

    the angle of the rod inside the engine shorter rods have more angle
  8. Our S650 HP compared to the C8.

    Nope. You're using the same amount of air each stroke, doesn't matter if you use bore or stroke to get it. You're talking rod angle/rod ratio now. That's not bore vs stroke. You can use different length rods in the same stroke engine. Again doesn't really matter much And again, another common...
  9. Our S650 HP compared to the C8.

    It doesn't really matter if it's stroke or bore. It's cubes. As I said the rod angle blah blah doesn't make enough of a difference to matter. You can make a similar cubic inch engine, one with more stroke and one with more bore and it will make the same power.
  10. Our S650 HP compared to the C8.

    I'll bite One big thing with DOHC is you can fit more valve in the bore. Two (four, actually) smaller valves instead of one big one. Coyote and LT1 engines have similar surface area in the intake valves (and the LT1 has much smaller exhaust valve surface area) even though the LT1 has a much...
  11. Our S650 HP compared to the C8.

    Different power curves, different goals, they used what they had (from the trucks + corvette) Let's remember GM does make a 670hp 5.5l DOHC NA V8
  12. Loss of power at 6,000 RPM 2025 GT

    He's referring to the power flattening out at 6,000rpm
  13. Our S650 HP compared to the C8.

    Mustang starts at 3,730 C8 Stingray? We recently got our hands on a 2020 C8 coupe with the Z51 performance package and promptly rolled it onto the scales. Its total curb weight came in at 3647 pounds, which is 195 more than the last C7 Corvette Stingray we weighed. You're looking at the...
  14. Our S650 HP compared to the C8.

    C8's are known for going 121-122mph in the 1/4 so it's still faster on the top end
  15. Our S650 HP compared to the C8.

    Also the EcoBoost
  16. Can I quiet the exhaust

    Do you have stock mufflers?
  17. COLD AIR INTAKE

    They don't do anything. It doesn't even make sense that they would work.
  18. COLD AIR INTAKE

    Throttle body spacers are a scam. Only useful if you need them to fit your intake back on etc
