My auto TA dynoed 300 to the wheels and ran an 8.7@83 in the 1/8th.

With just a lid, I put down 315... now I've got a few mods and a tune (nothin major) + a 80MM MAF and ported TB, I'm putting down 326 @ the wheels.... I think I kinda got a freak though... take dam good car of it

I race at 5800 feet up. Bandimere.

Stock LS1 F-Body's seem to run upper 14's. A couple get mid 14's. Not seen one deep into the 14's without a couple mods.

Gee I was finally correct for once..........

Except for the nun part, of course.....

Whats a dyno run show at that altitude for a stock LS1.??

Have fun......

Most dyno's show corrected numbers.
I did have a non-corrected graph printed out once though.

I made 376.8 RWHP and actual was right around 320 RWHP.

The one time I had it printed out was before cam....284.0 RWHP 290.9 ft/pounds un-corrected.
Corrected numbers.....335.3 RWHP and 343.4 ft/pounds. Correction factor tends to be around 1.20-1.25.

WOW that is quite significant, stock LS1 would be lucky to run 14's at 6,000 feet.

Thanks

Have fun

Tell me about it.

I should be in the 12's here at the beginning of next season though!

**svt_eater** · 09-29-2005, 08:18 PM

I went to the track stock 2 years ago with about 15000kms on my Firehawk T/A and ran consistent 13.6's. I did about a dozen runs in way to short of a time and the clutch started to smell on the last run so I kind of took the hint.

It sure took a good beating. It was about 40C(104F) and really humid. I still ran a 13.8 on my second last run with a buddy in the car.

That was at St. Thomas in Ontario, Canada. Not sure of the elevation, but not likely over 500ft I don't think.

I've heard that most are dynoing stock between 300-310, with some factory freaks at up to 325-330 at the wheels. I've just done the SLP bellows kit and all Royal Purple fluids in my M6 and the car feels like its gained a good 15-20HP...probably in my head! I've not made it to the dyno as yet. $75 to find out what it puts down seems a little pricey to me...although I do think bragging rights may have some worth.

**Zboner** · 09-29-2005, 08:20 PM

$75 is great price around here its $100 and for specials its $65.

BlackHawk T/A · 10-01-2005, 10:55 AM

I don't think i'll even bother with going to a Dyno just to get numbers...an A4 with a converter isn't going to be very impressive anyway.

**Bob'sWS6** · 10-08-2005, 09:54 PM

I didn't dyno my car stock. Right now it's pushing 351whp w/ a Z06 cam and a few bolt ons. Stock my understanding is that LS1's typically dyno as follows:

98-00 = 272-300whp (Depends on whether equipped w/ A4 or M6)
01-02 = 282-310whp (ditto)

The dyno numbers don't mean squat though, as obviously track times are what people want. Most bone stock LS1's run high 13's in a decent drivers hands (Dunno what downhill tracks, besides E Town, that people are driving at, but most tracks aren't exactly at sea level). In a sucky drivers hands they will run 14's. Of course there are freaks, such as the guys making 320+ whp stock, which is why there may be cars in the low 13's, but that isn't on average from what i've seen at Speedway by a long shot (And i've been there for years).

BlackHawk T/A · 10-09-2005, 01:37 AM

Mine is probably one of them at the moment...I can't even get traction from a 25% throttle takeoff...even as I ease into it the tires go up in smoke at about 50-75% throttle at 25mph...and I haven't even gotten into it yet

But not for long

**Bob'sWS6** · 10-09-2005, 11:00 AM

Yeah, i'm not stating that there aren't low 13 sec. LS1's, but they are few and far between. Not everyone of them puts down 310-325 whp stock. I read of some dude in a WS6 that put down 330 whp stock. That's almost as much as I have in my Z06 cammed WS6. I feel cheated.

(Typo, don't type at night

BlackHawk T/A · 10-09-2005, 11:27 AM

Yeah...I meant the comment about the high 13s maybe even 14s due to poor traction though.

**Killer_bluebird** · 10-10-2005, 11:16 AM

My Wife's 00 A4 Z28 did a best 13.4 at 104mph with only a K&N filter. Here is the Dyno:

My car is a freak and Dynoed 332.3 with a lid, K&N, descreened maft and 160 stat. See below the first run was with HPP3 (It robbed me almost 5hp to the wheels) My best 1/4 mile was 13.2 at 106mph on street tires with 2.1-2.2 60".

Here is my last one after the exhaust:

**Bob'sWS6** · 10-10-2005, 11:53 AM

Well having a 6 speed makes it hard to get outta the hole. That is why you only ran a 13.2 sec. 1/4 mile at 106 mph. I'm running a 13.1 sec. 1/4 mile at 109mph w/ 351whp at a 1300 ft elevation track. Of course I know i've got 12's in my car at the track, but i'm not the greatest driver.

Yup I Know. The car has 12's written all over, unfortunately the driver doesn't

. I just need a nice set of Drag radials, but since I only go to the Dragstrip once or twice a year I can't justify getting the them. Maybe next year after the cam swap.
