Default Am I wrong?

My dyno thread is here: https://ls1tech.com/forums/dynamometer-results-comparisons/860741-h-c-ls6-intake-heads-a4-441-8-rwhp.html and it seems some people in there think the car is capable of 10's with my power. I don't agree, but I wanted some other opinions. Mod list:

H/C 346 441 RWHP / 403 RWTQ
Stage III 4L60E w/SSF 3500 stall
Lowered on stock suspension save for pan hard and non adjust LCA's
Full weight, only missing the jack/tire and will be on 26" ET streets on Convo pros front and rears

I personally don't think the car will run 10's, I was hoping for 11.5X's. My logic behind it is I've only seen a few cars run 10's with that power, and they weigh alot less than mine with alot better suspension. ZO's barely run 10's with about the same power and less weight. What do you guys think?

Rear wheel #s don't always equate to the same times. As you mentioned you are making the same RWHP as some Z06 vettes do, but you're comparing RWHP through an auto to a 6 speed which is apples versus oranges.

In good air with a 1.5 something 60 foot the car could break 10s. I've seen 420 rwhp 3500-3600 lb cars do it, but everything needs to be working well together.

Your torque numbers suggest you should 60' well enough (esp. w/ a stall) and your hp numbers should carry the rest ... "should" be able to pull off a high 10's run

I was making 404hp and 370tq and ran the times in my sig. 40 more hp and 30 tq I feel would have netted me a 7.0 1/8 (10.9XX)

I made 440 rwhp thru a 5000 stall and a th400, car went 10.80 @123.xthat way with a 1.52 60 foot, 3620 raceweight

At 470 rw, same converter with a 1.44 60 foot the car went 10.57@126.5, and has been as fast as 127.4, 3500 raceweight


It's gonna have more to do with the weight, and how the car leaves then the power.

I have seen 3700 lb cars with 550 rwhp not run in the 10's( ton of those on this site, hard to get them to admit sometimes though), and I have seen 2600 lb cars with 350 rwhp run in the 10's.

as long as you have the traction and good sus you MAY hit 10s but mostly low 11s. the full weight is what will hold you back

my buddy went 11.1 w/ about the same power and same weight

also depends on how well your track is and elevation/DA

Take it to the track and run it and once you have some mph numbers we'll know exactly what it should be capable of.

The thing is the suspension is mostly all stock, and lowered, I don't think the car will 60' will be sufficient.

stock weight, stock suspension lowered, even with a good tire it's not gonna go 10's at that weight. If you're lucky it will 6o foot in the mid 1.5's at best, and at that weight I doubt it will go over 120.

You probably have a car that can run around 11.4 to 11.7 if I were to take a guess.

Exactly what I was thinking, I was hoping I wasn't crazy! If it pulls 11.5's I'll be happy. Last time out it went 11.6 at 117 on the old numbers.

Mid 11's @ 118-119mph. Get a PT4400 and go low 11's easy with some hookage.

What did it make before, and what have you changed since the last time you ran it?

The link to the dyno thread is at the top. Before it did 430/382, now it does 441/403. Ported TB and Pulley. 60' was a 1.67 so it could do with some improvement.

EDIT: I would get a bigger stall, but I eventually plan on spraying the car and going with a Vig 3200 or 3600, most likely a 3600, so buying a 4k would be a waste unfortunately. I doubt my TCI will hold up to a 150 shot on top of what its at right now very long.

I dunno how the converter will like it, I'd be more concerned about the 4ljunkie tranny not liking it....I'm spraying a 150 on a th400 converter that goes to 5400 on the transbrake, and it loves it

I'm not to worried about the tranny. It was built by a local shop who have built a ton, they built a 4L60E for a car that runs consistent 9's on the bottle for a couple of years now and it has had zero issues, given mine isn't built as strong as his, it won't see 9's. I don't think the converter will hold though.

i say with the stock sus id be more then happy with an 11.5. u most likely will be looking at a high 1.6 -low 1.7 60 ft time with traction. get it down in the 1.4's and a 10 is possible. a local car at full weight but a decent suspension made 15 less rwhp then u but 50 more lb ft of torque and cuts a mid 1.4 60 en route to an 11.001@121 mph.
