I joined this forum quite awhile ago, probably two years, and haven't posted yet. Bear with me until I get to the point of this post!
I am used to some ridiculously high hp cars and did serious
mods to my '03
Cobra "Terminator" convertible. I had 3 tunes in my handheld SCT tuner that were created by my awesome tuner, the owner of Racer's Edge Tuning in So Cal. I had the stock tune, a 98 octane gas tune using Torco for the added octane, and my E85 tune. The 4.6 liter
Cobra was making 850 hp with a 2.9 liter Whipple twin screw blower using the corn. You have to push about 30% more fuel using corn and I installed a complete fuel system with 3 high performance pumps, a -6 fuel line and rails, and 105 lb injectors. Of course I had a free flowing exhaust system with an OR/X Pipe, a giant "Big Oval throttle body" and countless other
mods. It was full weight, full interior with a 6-point roll cage and all the necessary safety equipment the drag strips wanted for a car trapping my times. With a 6-speed manual I was driving the car rather than just pressing the pedal and steering straight down the runway, so it was a blast and it took time to become pretty good and fairly consistent. Most often I raced Thursday nights at Irwindale Speedway which was only 1/8 mile, 660 feet. With 10" wide wrinkle wall drag slicks I managed 0 - 104 mph in 660 feet in 6.6 seconds. The big blower pushing 22 PSI would very quickly reel in smaller, lighter vehicles that could jump out of the box more quickly. In the 1/4 I was at 137 mph in 10.4 seconds. My setup made over 3 hp per cubic inch since the 4.6 liter is a 281 cubic inch engine. After that I bought a 2013 Shelby GT500 (5.8 liter, 662 hp stock). You could literal change 1 pulley to spin up the blower to a higher psi and add 80 hp. Thing is, there are so many dealers for parts like Ford Racing, Lethal Performance, and many others. Cheap and easy bolt on power.
Now, here I am in 2020 and I really, really like my GT1. It hooks up and goes but there is a major lack of power from a 40 or 60 roll. I mean it's quick but it can't pull like a freight train if you're cruising along at 70 or 80 and floor it. It's definitely anemic in that kind of scenario. I've seen the dyno sheets posted here and it tells the story . I could punch the pedal on my
Cobra while doing 80 or 90 and it would break the tires loose wanting to thrust forward.
My question to any/all of you is has anyone considered or is it even possible with available
aftermarket parts, to spin some larger turbos? Clearly you have to feed the beast as the only recipe for power is more fuel and more air in the proper ratios. So basically I'm talking intake and throttle body, enough to feed larger turbos; an exhaust system to handle the increased flow, and a fuel system capable of pushing enough gogo juice to get a nice, safe AFR.
This is all a moot point if there aren't the parts available for these relatively rare vehicles. However, if there are race parts to accomplish this, I think you're looking at about 575 whp and a lot of torque. That's getting close to doubling the actual stock output and would turn a Stinger GT into a monster in direct competition with Godzilla (nickname for Nissan's GTR, 3.8 TT 565 hp)
Thoughts anyone?
