Here are the corrected numbers for a very hot, 102°F day.

I'm still not sure just what it is you think you're proving here. That you can make a 2.8 that will get close to 4.9L numbers if you give it a shot of N2O? OK. So? If you do, and I cared enough, I'd give the 4.9L a 75 shot and then what? I have more power and torque by a long shot than you with the shot? Duh.

Go ahead and put nitrous on your 4.9 then. Dont' say that you can do it to get more hp if you want but not do it. If you aren't going to do it then dont' say that you could do it. Of course you could do it if you wanted. And you could also do it on your 3.4 too. And you could also prob put it on the family car.

But hey if you are looking for a nitrous kit to put on your 4.9 I have one for sale. NOS kit brand new for $350 shipped. Now you have no excuse for not putting nitrous on your 4.9. I am offering to sell you my kit.

After posting my shakedown nitrous runs do you still not think I can beat Earls 4.9 or any other stock 4.9 auto out there even though I have more hp now then what those runs show? Just answer yes or no. Cause this has been my point all along.

Edit: Those are some good numbers by the way. You have a strong 4.9. I think its kind of wierd how there is so much fluctuation between 4.9 dynos. A difference of 20-30 hp on some and even as much as 60 llb ft. Any idea why this is?

You pop the clutch and he steps on the gas .
You get a jump on the 4.9as you shift to second and he starts to hook up and his low end torque comes into play,
You are in third hit your nitro button while his torque pushes him ahead of you by 2 to 3 car lengths and even with you still spraying you cannot make up that gap in a 1/4 mile and I see you loosing .No way with him ahead of you that you will reel him in with a 2.8 period.

Edited:Post a pic of your nitrous kit I might be interested .

No flames just wanted to point out a few thing's...

ps. I am also going with the 4.9L 5speedTURD (as you think of them)

I can't say if you'll beat Earl or not, I've never seen his car or heard it run. It would be foolish for me to guess. Could *I* beat you? IF you left it the shot you have on there now, I think it would be a very, very close race.

I'd take you out of the hole and beat you to the 1/8th, probably by quite a bit. I think the auto can shift faster than you can, but it's gears are spaced wider, the 1-2 shift is where you'll maybe start making up some ground. End result, a very close race (me winning, of course ) and you might run a higher trap speed by a little.

Of course, if you feel threatened, you'll just pull the 75 hp jets and put in some 125's. There would be no way of knowing what you had in there. But IF you raced me with the engine on the dyno sheet, I think if we raced 10 times I might beat you 6.

Of course, since you won't go to a track, we'll never find out.

No idea on the numbers except for the fact that we did clean the injectors, make sure everything was in top tune, and it has a very free exhaust system. Personally, I don't think they're great, if you look at the corrected numbers and estimated engine hp from them, they're very close to the factory rated numbers. It's just running like it should be.

Ok let me save you some time...... I know for a fact You would of lost It would of not of mattered if you hit the nos early or later... Like master tuner said...... It's very hard to play catchup on a 1/4 mile run.... Plus I had a little ace up my sleeves with the gearing in my tranny and the TC..... Still a stock engine tho But when I put a higher stall speed in the th 440 with the 2:73 final drive The higher stall speed TC gave me brutal faster launches and higher gearing for faster speeds..... Plus I went with lighter springs on my distributer for nice timing advance Since mine used the mechanical dist..... If you ever drove a carburated 4.9 it is night and day when you go with lighter springs on the mechanical timing

BTW the blue springs work very well on stick shift 4.9s I went with the black ones for the auto. Anyway if you don't believe me we still have till oct 8th before I drop the cradle on mine for the 100th time..... After that it's going to be getting a nice little turbo and a lighter tranny... But in my opinion unless im a good shifter then I will never count a stickshift as a proformance upgrade over a auto. Anyway You are right about your car being lighter The 4speed hydrolic shifted auto weighs a ton

Now those cheap aftermarket parts that don't count as bolt ons make a huge difference...... Oh I forgot to mention the exhaust... Teee hee hee

Earl the TC that you installed does not change your gear ratio. You still have a 2.73 according to you. The only difference is more rpm for brake boosting for a better launch. You are still stuck with your 2.73 gears though

Lets say your 4.9 was making 200 hp as it sits. How much would you say your carb added? I mean you are still stuck with the stock cam and heads. airflow in that area will be the same.

It will be like Arn going from his efi to a carb. he claimed up and down it felt better and seemed faster. His car was actually slower in the qtr mile after he installed and tuned his carb. Now after his slower time he knows he has to tune it some more. My point here is that just adding a carb and driving it around town you aren't going to be able to tell if you are actually making more power or not.

Now I am not trying to cut your 4.9 with the carb on it but you really have no idea other then a butt dyno if it makes more power and if so by how much.

If anythign earl since you are putting a spd tranny in and you live fairly close to OSW, I would take it there and get some times in that way you can see just how much a 5 spd tranny improves times over the 440 wit a stall converter.

MTA, yea I might just lose if I dont' use my nitrous till 3rd gear but why would I do that?

So yiou say I will have him out of the hole, have lead into second lose the lead in second gear and then not be able to get it back in 3rd when I use the nitrous. Now what if I use the nitrous in first gear as well as second gear and then in 3rd as well which is how I would do it if I raced from a stop. According to you I would have him out of the hole and then with my ntirous in every gear I should be able to still "barely" beat him . I mean tthat at least 40 hp extra Ihave from 5200 rpm up has to have some roll on the outcome of this no? I know that when I race a car that has 40 more hp then me up top I get walked hard in third gear. I actually raced an SRT-4 and I had him till 3rd but even then he came by me like I was standing still.

Sent you a pm earl.
