I have been curious about this and I havent found a post about it (only HP) so post them up. If you make over 430 ft-lbs and meet the following:

-Stock 346 bottom end
-Pump gas (no race gas, or mix, just strait pump gas no octane boosters either, if you dynoed with race gas, dont post)
-No power adders, just NA cars

then post the following info:

-dyno graph (SAE #'s only)
-compression ratio
-fuel octane
-setup description (cam, heads, intake, ect)

I know we have a lot of setups making good torque and it seems to thin out at 430 ft lbs, I just would like to see how different setups are doing.

450 rwtq....oh wait, nevermind

way to screw up a thread you *** lol, here is my car...

-AFR 205's at 61cc (-0.6 cc relief)
-0.040" gaskets
-11.4:1 CR
-93 octane
-230/232 on a 112+4
-Ported FAST (by Mamo, noone else touches my **** lol)
-Ypipe setup with cutout

smoothing is at zero because if I didnt do that, the loss of the rpm signal gives me a peak of 598 or something lol

441 rwtq

Have any of these 430-445 ft lb h/c cars trapped over 125 or 126? At full weight that should be pretty easy to do.

Of course my dyno never reads as high as most out there but I've never seen more than 415rwtq with the big Cam/Head setups yet.
Probly the highest RWTQ was out of my buddies 224 Cam/Home ported head / 11-1 comp setup. He made 435hp/425tq.

I probly could hit a higher TQ # but the cars are 100% street tuned first so there is no detination.I'm sure on the dyno I probly could up the timing to raise torque but it would KR on the street

2002 Ws6 Stock bottomend
Home ported 4.8's
226/226 cam
ls6 intake, Hooker headers, dual exhaust...basic stuff really

421rwhp, 420rwtq.....you could really feel the torque in the car, made a heavy car move good for such a mild combo.

Jeff,
I agree 100%, any of these high rwhp cars should lay down some serious MPH.

I will hopefully have some track time in about 1.5 months.

I should also mention that my tune I dynoed on was a tune strait off the road, was not touched on the dyno and I get no KR on the street.

Not trying to pee in your cheerios or anything, but Id like to see you make some passes, a 100% pass should trap 127 or so at full weight Id say

Hell Fireballs stock bottom end, runof the mill ported 5.3 heads/Trex cam trapped 128 or 129 a few times and went 10.40s at 3400+lbs on 460 rwhp/410lbft. Some of these cars should be able to do that at 3600 Id think

3200 lbs and 500-530+ rwhp Im waiting to see some 135 mph traps. LGs car did it a while ago but far far from setup to go fast

My former mild mannered 346 build routinely made 435 RWTQ with a few hail Mary runs in the 440/441 range and consistantly laid down 475 RWHP with a few 480/481 runs in there as well. Impressive for a cam with a wide LSA (114) and only 1 degree of advance (113 ICL)....of course the fact it was only 228/228 helped keep overlap down and the intake closing points were still ideal enough to allow that to happen.

MPH did back the dyno numbers (as they should) with a 3450 lb C5 trapping 124 at an "OK" 1500ish positive D/A.

I'm not surprised Mike's car puts down stupid TQ numbers with all the airflow related mods covered (efficient 205's and ported FAST 90) and a cam that's sizable with a reasonably tight LSA, small split on the exhaust (less overlap), and an early intake closing point because of his chosen installed position (108 ICL). I encouraged him to install it straight up at 112....my best guess is the TQ would have been a little less (433-435), BUT, he would have probably cleared 480 RWHP and the curve would have opened up more after peak power.....I bet a 12-15 HP delta at say 7000 RPM. But lets face it, the strong TQ is really fun on the street and 470+ is still impressive and will pull upstairs with authority.

Again Mike....nice work (when is the big stick going in?.....LOL)

Tony M.

PS...I checked the 440+ on the poll with probably a half dozen runs eclipsing that mark, but the reality is I probably had 50+ runs in the 435-437 range which is what I normally quote. As soon as you put some stick to that car (or back the cam up currently installed), your peak TQ will pay a small penalty but the gains upstairs will make that a very acceptable trade off.

honestly Tony Id expect it to mph a bit more than that, but its hard to compare different cars/tracks/drivers etc I know of a lot of 380-410 hp cars trapping 119-122 at weight, another 60 Id think it go 126 all day

HOSS

iTrader: (12)

haha, he has to get off the line first, and Mike is scared to break the rear end right now..probably because I have been through 9 of them. He was trapping 93 in the 1/8th before the milled heads and ported FAST with a shitty 60' and shitty track. It's a very strong car, feels a helluva lot stronger with the new tq.

Tony Mamo @ AFR

Let's be real for a minute....how many stock displacement H/C cars have gone significantly faster than 124 MPH without even taking D/A into account?? The reality is that not many H/C stock displacement cars see better than 124 (a small percentage) and the few that have usually saw closer to zero D/A....and some of them quite a bit below sea level. It's ALL about the D/A. The former package in my car made excellent power all things considered, did so on a half a dozen different dyno's, and did lay down a respectable MPH at the track.

If I were to have run my car a little bit closer to sea level it would have been banging right on the 126 mark (probably 125 and alot of change). If I had the opportunity to run it at 1000 feet below I would have easily cleared 127 MPH....now everything seems right but the reality is nothing has changed.

The numbers are right where they should be for that weight and power output...many a sliderule and a computer program would back me on that.

A new C6 Z06 with less weight, a 427 cubic inch engine, and more average power (or close to the same) goes typically 125 MPH....once again, about right all things considered.

nhra doesnt say nitrous is a power adder, so 444rwtq @5600 cutting out , otherwise 320

well this isnt NHRA once you add n2o to the game, thes numbers sky rocket.

Id say 40% of the h/c cars around here that get raced regularly (I know of 5)have been 124-126 around that weight on some good days and most are your average 430 hp cars. Add 60 hp in the mix and Id hope an average day it traps 125+

All I know is that 450 on our dyno at 3600-3700 lbs traps 126-128 as weve done a few times, and Im sure some of these 480 hp cars could make 450 on ours

Not to muck up the thread here. Granny, I have seen some of the cars you speak of first hand and will say they are quick, but I think a lot has to do with where you guys are located. Even with a high DA, you guys still have better air then most of us. Combine that with a down hill track, and there is your ET's. While keeping up with the thread, I have no dyno numbers, but a 3600lb car that runs 11.5's @ 121 in a M6. I'll take that over dyno numbers anyday.

PS - Ask Larry about the down hill tracks.

I agree, not to be mistaken here. If the car dynoed 300 hp but ran 11.0, thats all that matters. My intention here was to see how different setups were working. So far, all these cars arent even radical setups, yet run just as hard, if not stronger, than some other more radical setups with bigger cams and high compression. Not to mention the mid range makes driving the car around daily a hell of a lot more fun haha

Lets be honest here. there are alot of Bs dyno numbers on this board. Tons of guys claim 450 + rwhp and can never back it up. In the last month I have raced from a roll 40mph - 140mph 2 450+ hp cars 1 from a sponsor on this board with a 395ci stroker and and 1 from a big sponsor from the corvette board. I pulled on the stroker and was dead even with the other....

Btw I have a A4 car that makes 365rwhp unlocked..... Suprise Suprise

Oh yea and ofcourse I layed both cars out big time from dead stop......

There is always a some m6 guys that only makes 400 rwhp and run 11.5 @120 at a regular track night and stock rims all around. Not at a special winter rental with extra prepand staging with there rear tires...ITs hard to explain but there are more tricks flying around these days than ever.

I think most of us know some shops always dyno much higher than others and there own pkgs always make the most power,, Real numbers or not

ok lets get back onto topic
