Pred Z...
So running that cam you suggest with the heads milled down to 62 and .040 cometics, that everything should clear safely?..

if i remember right, they were milled to 59cc's and are compression was around 11:7. flycuting had to be done on both intake and exhaust. this profile will make the power.

PREDATOR-Z,
In the thread you are quoting the torque number is 385, which is in line with the modifications there...

I am again questionning about those 485 RWTQ not RWHP????

At what RPM do you think this amount of torque is attainable on a 346Cid?

Christian

PREDATOR-Z

61cc chambers and .040 cometics will clear that cam.

PREDATOR-Z

Chris, step out of the box

385rwtrq {A4, LTs and Duals, 3600 stall (that is it)}, that is strong trq, not the normal.

Now I said LOOK at the whole picture, not just 346 and cam. Look at exhaust, heads, intake, MAF, induction, then go deeper, valves, cfm of runners, lift flow etc....
Only with all this info you can call BS if something doesn't jive.

With the proper parts, attention to details (****), hours of tuning, the right VEs, that number can be achieved.
If 400/400 can be done, 500/500 can also be done.
It si all in the right parts.

honestly i dont think 485 rwtq can be reliably made without a fair amount of compression 12.1+, and of course the proper valve events..... but under that i dont care if your the best tuner in the world, and perfect cam/heads combo, a 346 is only 346, just not enough displacement to make that much torque, with let say 11.25-11.5 compression.

PREDATOR-Z

Funny you say that, I run 12:1 on a daily basis ( all you need is good fuel and tuning)

Ryne @ CMS

iTrader: (10)

my 434 i run 13.5 compression, but i also run the car on VP-MS109, i am talkin about a average daily drivable combo like 11.25-11.5 compression max.

PREDATOR-Z

Yeah mine is average forged 370 cid with a super stealthy 224/222 .609/.578 117.5 LSA, 12:1, 98 RON fuel, TR6 plugs (.035 gap), 8.5 DCR
You should see my trq, feels like I'm driving a 408

I'm sorry for the typo. I was refering to Patrick G's cam which made 508/445. I got those numbers mixed up with my friend's 03 Cobra who put down the opposite: 485 Horsepower/509 Torque.

I believe Patrick G had his DCR at 8:92 in this combo. This was not a cheap combo either with Titanium hollow stem valves, Yella Terra Rockers and Titanium Retainers in his Valvetrain. I believe the upgraded AFR valves assisted in the 445 because his mid-lift numbers were incredible. It was also a forged 347 also I believe.

ON THE RWTQ,

Let's make it simple, as simple as a short calculation.

Horsepower = torque x rpm / 5252

485rwtq x 4600 / 5252 = 424,79rwhp @ 4600 rpm (never seen those number on a street car)
or
485rwtq x 5100 / 5252 = 470,96rzhp @ 5100 rpm which in theory will lead to ~ 545 rwhp @ 6900 rpm !!!

Assuming you run a combo still drivable on the street with an IVC ~ 48* and EVC ~ 8* (pretty much the max in term of drivability vs. power, you may define the rest of the VE as you want)

It is an ineptitude to beleive you can run under an SCR of ~ 13.5/1 to reach those 485RWTQ, and it would be impossible to run this engine on a 93 Octane...

If you have a way to make it happen, I would be more than happy to learn it and prepare my rear tires to suffer a little more...

Didn't notice your numbers currently. 511/455 - Don't get greedy now!

Hi 02TransAm/Batmobile,

Thanks to make the point clear on the TYPO...

Now time to go back on topic about what cam for AFR 205...BEST TO ASK IS THE DESIGNER

I know that LG motorsports has been putting up some great numbers with there G5X3 cam with milled AFR's...I might been lookin into going this route...Allgnc5 has this set-up and put down some badass numbers...

Kev

JPH

iTrader: (2)

all this talk about 485trq., if i'm not mistaken his goal was 420+trq. well there is enough info here to get you there man, you decide.

50_Dave

Allignc5 has a modified form their G5x3 cam. He did put down decent numbers though. I put down 30 less hp with afr heads unmilled with the g5x3 cam, and like 20 less torque then him; however milling the heads and porting the intake will catch that up with the quickness.

Sweet set-up man...Those are some stout numbers for some out of the box and unmilled 205's...Plus, without any porting on the FAST intake...
I am really looking into this set-up...The numbers are proving themselves time and time again...
I gave LG motorsports a call yesterday and they said that I can run the 205's milled to 59CC with the G5X3, and everything will clear...That was with cometic 40's even...Then he said that the compression would be 11 to 1... If I run that in piano's calc if get a SCR of 11.8 and a DCR of 9.01...If this were done with 61CC chambers then this set-up would be money...Thanks for all of your help...

They told me there would be a 50/50 chance on PTV clearance issues if i milled the heads with the g5x3 cam.

wow, they said that huh?
good luck with your set up.
