I’ll respond to everyone together so this will be a long post.
Very impressive and believe it’s the best I’ve seen for a JB4 Stinger. However, most of those Stingers in the 490whp range are FBO and using WMI which is good for another 20-40whp. Most I’ve seen without WMI is 457whp but he did 490whp/574wtq on e30 only. Also I was really talking about the stock turbo record in general, not his dyno run specifically. 490whp seems to be the highest posted results with or without WMI for our Stingers, but good to see you got close to that number too.
Not sure what planet your on but HP/TQ results are the most widely used comparison for vehicles. There’s a reason all manufactures post HP/TQ results and only a few even provide 0-60 or 1/4m figures. Way too many variables affect those results(DA, weather, traction,etc) and one vehicle making 500hp can be slower than a 400hp car for ton of reasons. Most people nowadays trust and compare STD Dynojet results, because it’s the universal “standard” and used across the world.
Track/dragy results are nice for those that have the most ideal conditions, but everyone knows a prepped surface in FL cannot be compared to a lousy street in the high elevation mountains of Canada. And to answer your question, traction is why my buddy doesn’t use or care about track/draggy results. Too much power for street tires and isn’t taking the chance of hurting his drivetrain by using drag radials just to get a number someone might beat simply because they have better conditions...
Bottom line, the most recognizable & easily comparable results we can use and discuss are the highest HP/TQ dynojet numbers from each vehicle. Since more people seem to be comparing dyno results and that’s getting more popular across the internet & social media I think it would be best to evolve and follow the current trend is all I’m saying. Yes it may be for bragging rights, but better numbers will only help progress our Stingers to the international stage and get more people interested in our cars.
Sorry to hear that you won’t share something to help our community and progress the Stinger platform just because you’re worried about what others might say.

Welcome to the internet. Lol
As I’ve said before, I agree dynos are mainly used to show power gains for
mods on individual cars. However, those results arent faux records, they are real records showing the best results people can prove to everyone else that cares to see them. And in today’s social media and networked world that’s basically all that matters, whether we like it or not.
