Posted this in track kill stories with not much help.. really curious where this car will stand when the track opens up.

I don't track often but what would a lt1 trap with a dyno of 311hp/329 ? Going when they open up, and since then I've added a computer tune and cutout. ________

 

well i know a guy up the road has an ls1 dynoed 340 hp to the wheels and 338 ft lbs and he ran 13.5 best, that was with 411 gears and m6.

 

id guess around 105 mph.

 

Engine or RWHP?

Engine I would suspect somewhere around 99-105 on the high end depending on conditions/driver ability.

RWHP- probably closer to the 108-110 mark.

Your traps are likely to be more consistent than your times. When I was going to the track I would try different things, sometimes the times would vary upwards of .5 second, but the traps were all within 1-2 mph. To me- trap speed is a better indicator of a cars true power than the time. A crappy launch or poorly setup suspension can really hurt a car's time, but the trap speed will usually be fairly consistent all other things being equal.

 

Dynos vary, but I would expect at least 12.5x's @ 106 at that power level. I put down the same power and run 12.82 @ 104 pushing 3900 lbs.

 

That's to the wheels.. sorry for not saying.. since my dyno I've added two power mods cutout and a tune and freshened up old parts.

 

I would say around 103-108mph..

 

I trapped 103 with an estimated 280-290 rwhp.

That being said, there's tons of variables that aren't accounted for in the OP's post. Elevation, tires, etc. I'm guessing it'll be in the 106-108mph area but the best bet would be to take it out and find out.

 

My car was 379rwhp and i trapped 118 before i changed my tune. 3000 stall 4.10 gears and a4 with spray. I was also at 503 ft lbs with the spray
