Wow, nice numbers - I wonder how much a set of cats on the back of those hookers would pull that down, 10 hp maybe?

Well, this is a thread titled "New Dyno Numbers".

And to play devils advocate with you, track times mean nothing (times, not MPH) if your driving is all done on the street and you just want your car to move when you punch it at 30, 50, 70, 80 mph. Dyno numbers are a better indication of that kind of performance than e.t. at the track, which is a product of how well the car hooks - you can have a car that hooks up like a **** and runs a blistering e.t., but isn't as fast on the highway as another car with more horsepower that runs a **** poor e.t. due to no traction.

Gomer, sounds like great results all in all. Looking forward to seeing the dyno graph.

TTopJohn i couldnt agree with you more, but as for the hardcore racers here we want to see what the potential of the car is not just the h/c package, because if it works on the dyno and not the track, we would want to know that before buying similar setups that dont perform at the track.

Like I said in an above post.. my car WON'T be on the track anytime soon. It has a stock rear, it won't E.T. good at the track but it will eat my brother's 11.62 car up all day from a roll, because he has an auto and cuts 1.58 60ft times. The car is not set up to E.T.. it is set up to out run other cars on the street and it does that wonderfully.

Do you have a graph you can post? I would love to see one, those are great numbers for such a stealthly can, congrats!

Yes, I'm going to post a comparison graph on the 412rwhp run and the run a few months back before the rockers, pulley, and TB when I get to work Tuesday morning.

Gomer, congrats on the #'s. I have always been interested in your car because I'm going with a very similar setup (TR220, Ab Speed heads) that are being installed as I write this. I've very very pleased to see that a small cam and good heads can make great power (and fantastic TQ, you are nearing 400!). Even if the car doesn't get to the track, you know by the seat of your pants that you have a strong runner.

I have one of the comparison graphs here at my desk scanned if someone will host it for me. Mail me if you can do it.

Here is one of the comparison graphs. The red graph was before the pulley, TB, and Rockers... the blue graph is after. The place where the torque dips a little is where the car is really rich ( around 11.8 to 1 ).. I know some tuning will pick up my low end alot.

Again, nice #s gomer!

Out of curiosity, what valvesprings are you using?

gomer

iTrader: (13)

The large duals that PP is using. I can't remember which ones.. you think that I may have some float at the end of the graph? It looked funny to me. But on an earlier pull I had a big spike at the end of the graph like is normal and I asked the operator if there was something he could do to make it not have a spike.. so maybe it was just something he did.. I know he didn't hit the rev limiter on that run as hard as he did the one before.

On the "red" graph. that was when I was running 918's.

Nice #`s Gomer! You like those Yella Terra`s ah? We got a cam that will work for you when you want to go bigger, but sounds like you have got the right setup already. Have fun with it.

I do like the Yella Terras, they made the valvetrain a little less noisy. I really want the power of a larger cam, but I don't know if I'm ready to live with the hassle of a big cam unless I can gain AT LEAST 25rwhp over what I have now. Do you think I could gain that?

Nice numbers again, Gomer, that's awesome news for people who want good idle and smoother power! Btw, I resized the graph a little smaller so it fits better in the forum, let me know if you want it larger.

Gomer, I noticed you unplugged your iat for your 411 run and picked up 11 hp, Did you look to see what your a/f and timing was during that run, looks like it bumped the timing and leaned it out, bit of a dyno trick but it may indicate what your car will pluu with tuning. where is the 416 pull, why not post that graph

gomer

iTrader: (13)

If you would read a little closer you would see those two dyno runs were made 2 and a half months apart. And read above the graph, it says that it is a comparison of before the pulley, TB, and rockers. The title "unplugged IAT" is kinda misleading, it wasn't "unplugged" meaning disconnected, it was just moved out of my airbox and into the ambient air.. my car only makes 22degrees of timing for some reason and the IAT's that day were 115degrees and wouldn't change, it ended up being a bad IAT. So it is not a dyno trick, don't come in my thread starting your ****. And the reason I posted this graph was because it had good information regarding the gains associated with some bolt ons, the the other graph wasn't a comparison one. Are all these answers good enough for you?

Allright!!!, lets start duke'n it out. I have a question, why does your 411 pull take a nose dive at 6k? If your other pulls are similar, I'd get tuned and see if you can fix that. If not just ignore the question. But great numbers. Is the TR220 really a "baby" cam? It's on the high end of the mild cams. I just got a similar one and I'm kinda worried it might be too big.

gomer

iTrader: (13)

The other two pulls that day looked "normal" meaning they had a spike on the ends. I asked the dyno operator if there was something that he could do to keep the graph from spiking on the end, so I think he may have "rolled off the throttle some" before ending the recording?

And Yes, then TR220 is a very very tame cam. I have the stock tune and There is no starting or surging issues at all with it.

I wonder about the powerband also...The smaller cam doesnt peak as high as some of the larger cams but it seems like it should peak a few hundred rpms higher though...Could tuning help that?

gomer, is your TR220 on a 112 or 114 LSA? The bottom end on my stock headed TR220/114 car is a tad stonger, but of course my peak power is quite a bit lower.
