Dynamometer Results & Comparisons - 429.2 Rwhp 397.4 Rwtq Gto

EDC put me a package together in my sig and by god it works.Stock shortblock and all the bolt ons.

Awesome TQ on that thing!

Ed was right on the money with his camshaft.The GTO is + - 3950 lbs with driver and the TQ is the only thing to help my ET.Thanks Cannibal

nice, what did ED spec your cam too. mine came out 238/236 .586/.589 112+0.

im hoping for more hp and tq myself. are your AFR's milled? and you spun it to 7k :eek:

My cam is a BABY,220/224 597/579 112.Spun it to 7000 but 6800 seems to be it.No milling at all on the AFRs.Pistons are .010 out of the hole with cometic .040 gaskets so at .030 quench we are making some extra squeeze.The car idles like a baby and the only problem I am having is the Fast 90 mm TB sticking but I am working that out slowly.

do you know what lobe's he used? im not asking for full spec's and everything since i know he doesnt like to give out that type of info. you can PM me them if you dont want them public, i wont post them. im just curious to see how he spec'd your's out because your the only peron i've seen post EDC results. mine should be in soon.

did you have your heads flowed or did Ed use his own AFR data?

those are great numbers considering the small cam and stock compression.

ed spec'd my cam for road racing as i've got a forged 347 w/ 12.02 CR h/c and full bolt ons minus the 90mm TB/int.

why did you go with a 90mm? did you get an upgraded Intake?

Fast 90mm intake too,thats all it will fit.

those are the numbers i am going for.. but i know i dont have the money for a BMR driveline. what all did you replace? I am shooting going to do heads/cam and clutch pretty soon. then sometime after that i will do LT's i am shooting for right around 400-425 hp... mti 114lsa with 2E heads. what do you think about that setup. i am pretty much retarded when it comes to all this stuff so any advice will help.

Anyones stuff will make the #s if you match the components correctly like EDC did for me.Talk to people and do not buy an off the shelf cam if possible.I pretty much replaced everything in the driveline,gears,harrop cover,BMR CVs,driveshaft,axle stubs and rear yoke,and an Exedy twin disc is sitting on my bench waiting for my B&M shifter.

you must be a rich man with that driveline replacement list and an exedy.!!! :secret2: what did you say your address was? :secret:

im even more impressed with the setup. its a great combo thats for sure.

also gives me hope for my numbers :D :devil:

A 220* @ .05 cam, making 430rwhp w/ a goat's IRS :D

Gotta love it.

Add 2-2.5% for the IRS loss and we are up in the 440's with a baby camshaft.If it was only in an F-Body maybe the car would ET.Anybody have any guesses on ET with these #s ?Car has 3.91 gears,+-3950 weight,ZO6 ratio M6 on Drag radials.

May I ask why you didn't add compression? This guy did, and he has more power across the whole rev range:

'Course for someone with stock compression and CATS through IRS, those are some damn impressive numbers!

Dude,the LG cam is huge compared to what I have.It has like 20 deg more duration and a ton more lift.Compression has very little to do with the difference in the #s.I would not put a cam in that size and ever call it my daily driver(many do).Just my .02
Anthony

This guy got 418 with the stock intake here (http://www.ls1tech.com/forums/showthread.php?t=252201&highlight=gto) And the stock exhaust but a slightly bigger cam.

:lol:

apples to oranges, the big cam needs the compression. plus the x3 has at least 14* of intake duration and 20* exhaust duration witht a shitload more overlap. plus the LGM headers are better then anything the gto or fbody market for that matter. add the fact that the fulll point of compression is worth a ~4% increase over the whole range.

What about this guy then?

All have more power ACROSS THE ENTIRE REV RANGE than you. That's up high AND down low.

I'm not saying your cam is wrong. EDC knows his stuff. I'm saying you're leaving power on the table by not milling the heads. Or maybe you have a tuning issue?

Is it a GTO thing? Seriously, I don't know that much about GTOs...

You are comparing apples to oranges still.They all have EWP,No cats,larger cams and yes a little compression.If you do the math my pistons are .010 out of the hole,.040 cometics,66cc heads.That gives me 10.85....... compression,not too far off 11:1. I can always put a huge cam,EWP,and remove the cats and never drive the car if that would make the # that you think I should be making.

So you're saying that if the dynographs recorded 900 RPMs through 2500 RPMs, your setup would be ahead in that range? I'm not really sure what you mean by "drivable." The second two links I posted had cams with under 230 duration and fatter torque curves than you.

I'm not saying there's anything weird going on here. If corvette LT's are that much better than GTO ones, then with the cats and the compression then I can see the power difference. I'm just asking, why didn't you mill the heads and have Ed grind a cam for that?

Maybe I'm confused about the "drivability" thing? I thought if a car made power low in the curve then it was "drivable," and those cars made more power across the entire curve than you. I am not an expert here and I am trying to understand this...

:werd:. but your not at 10.85 CR w/ 66cc chambers regardless of deck height and quench.

black knight, find me a car (fbody, Ybody, or gto) running stock compression, cats and a cam smaller then 224* and puts out more power then this.

The cam I have is still only a 220/224 cam.There is only so much duration you can throw at a car that wieghs 3950 race wieght without hurting ET.I am really not trying to dyno race here as the results will be seen at the track.Too bad there is snow on the ground here.

Remember it wasn't that long ago that I made 423rwhp 398rwtq with at 221/221 .558/.558 114lsa cam in my car with a set of TSP raceport LS6 heads. Even though they had 59cc chambers I was running a .052 gasket. Also, the most important part of that combo was that I did that on a LS6 intake and stock ported TB, not a 90mm FAST intake.

I think the GTO numbers are "good" but not anything to get too excited about, especially when you consider the amount of money spent.

Great numbers! Spray that thing!

brain fart; CR is 10.8558..

thats very true scott, but i tend not to use your car as everyday numbers ;). these GTO's are also starting at a lower base then the typical fbody, i remember seeing alot of sub 300rwhp stock dyno's.

this same setup in an fbody with stock gearing would be 440/410rwhp car; do you not agree? slap on a bit more compression, ORY, EWP and you've got a 450rwhp+ combo, all done with a 220/224 112. in an fbody at least.

I sure wish EDC would hurry up with my setup :cry:

You know I can't! :) His is surely the best with those criteria.

That is what I am telling him to do.

Launch at a higher RPM, and slip the clutch more to control wheelspin? You don't need low-RPM torque if the car never sees low RPM.

He said his first priority was for it to be a daily driver, so remember that. But the combos that I posted links to DID have more low-RPM torque than him.

I also want to see what it runs. Im very curious since my truck will be probably close to those numbers on the spray and about the same weight.
It will be a rough estimate of course.

Good deal Tony, glad to see you got the car back together! Wanna throw a reverse split cam back in it? :) J/K

Thanks Jeff,The car runs just a little better than before.You were right about the tight LSA.
Anthony

Wow, nice curves. Very impressive, even up to 7k!! :)

I sure wish EDC would hurry up with my setup :cry:

We're all set... ;)

Anthonyi'm not asking for numbers,but is that cam reverse split at .200 lift or above?

Edthanks Ed.just curious :)and yes,those are impressive numbers for that baby cam.

Tony, let us know what you run. It might not sound like it from before, but I am damn impressed with your numbers, considering that you're running compression for 91 octane, full exhaust with cats, and a pretty dyno-unfriendly drivetrain (gears, GTO IRS, etc).

Thanks a lot,You are one of the first to notice the difference between the GTO and other LS1 cars.I will be hitting the track as soon as they open at the beginning of next month.The only problem is I drive a 6 speed like ass so it will take me a bit of practice to make a fair evaluation of the car.I'm looking for someone to be a shoe in for me that can drive to see what the car can really do,but until then it's all me.

Anthonyjust keep an eye on your trap speeds,don't worry too much about ETs at first.i can't drive a stick that good either,lol.

Traps are what I have to go for in the beginning.

Thats a fantisk combo. What state do you live in. And do you have to pass smog?
