Thanks

i think the curb is like 3730 on them or something ? So about 40 lbs heavier than my car if both stock and full fluids


He has some. odyssey battery, front k member, rear seat delete. Lots of solid bushings and tubular suspension parts etc. car rides like a hay wagon, drones terrible and the spool is no fun on the street. It’s a bit much for a daily driver as far as comfort etc Probably lighter than my car as it sits right now. In full drag strip setup I’m prob lighter but not positive. he had a passenger in this race and I didn’t so I was surely lighter here

Definitely he has taking weight off the car which makes the runs more impressive , car seems to be moving very well .

still need to dial in the tune but I’m sure it’s pretty close PRAY’s tunes usually are. If anything the shift points might need adjusted id guess.

he needs more seat time and we honestly don’t know for certain how well it’s running right now/true dyno numbers on 93. But thanks yeah I’m happy with it

Good runs. But on 93 hes probably around 600-650rwhp at best. E85 and race gas is usually a 100rwhp bump for these cars.

gotcha. He was 76x rwhp on 110. So that puts him roughly 660 rwhp then?

we will see what it is making on June 4 like I said. He’s getting E85 done and dyno tune

Yeah I was going to say that the 700 on 93 was a bit optimistic, but I choose to avoid the whole "you're just butthurt, go cry some more" crap....from others, not from you. I saw nearly 70 horsepower difference between 91 and E85 on my turd. Either way, your car is badass in my book.

660whp weight reduced cobro pulls a nose on a 490?whp camaro. As expected.

Good run, car runs hard. Terminators are heavy cars for sure. I wouldn't really consider the rear seats being out much WR since they weigh practically nothing lol. Not knocking your car any, it obviously runs hard. Would love to see him on E85 and no missed shifts vs you on kill.

Nice job! Terminator might need more seat time. I would have expected him even on pump to be deadly past 100MPH

490 rwhp before a bit of tuning change with injector timing and ram air mod. Probably an honest 500 now

thanks. He’s got a lot more WR than just seats.

if he gains 100 hp from this im gonna need more than kill mode lol. Me set on kill vs his car perfectly driven as is would be a Good one but idk...

These are the posts lacking any details that always concern me.

Red2k what is exact weight of each car?
What is exact rwhp of each car?

Humor our readers for a moment-

2 cars weighing 3700lbs
One with N/A A8 500whp (states owners guess)
Other manual but 580-700rwhp
Pull from 3rd to 4th gear Cobra wins

Does this truly solidify any data on how bad Cobra runs or how well LT1 runs?

Am I only one who prefers true data?

Hell, does anyone know what upper pulley size he’s running on the 2.9?

This is mystic z28 aka redfury aka the most banned troll in this section's history. You've banned him 23 times and he just comes back with a different name. Mustangs stole his innocence back with his old supercharged Pontiac.

The data in these posts is a f$cking joke - I’ll get it sorted out. This is ridiculous

This seems to be the norm for private sales of cars that make xxxwhp. Almost always end up running like ****. And people still go out and beat on them without validating what they just paid for. Dummies

Wasn’t a certain member here not much faster than me with his blower swap 93 octane sra Cobra? Considering the extra passenger and limited seat time the results look about right to me ? I just texted him and asked about pulley and psi.

ive tried to be as honest as I can and provide all information best I can. Not sure what else I can do. Compared to many other threads and race comparisons I have provided much more than the norm. I’m not a liar and I have never mis represented anything on here with my car or any racing
