Not if it comes on progressivley, like in a 4-5 second spread.

I don't really have an interest in the 1/4 mile. Although I'm certain I'll go to the track with my friend and use his Hoosiers to see what it'll do. I also probably will not have the whole 300 hitting at once, maybe some other progressive hit.

Don't bet on it. If you gave that motor to ARE, you would probably never see it again

Quickin

Progressively, why not? Its like an 800 RWHP Supra getting into its boost from a roll, right?
I'm sure a full hit of a 300 shot would light the tires.

Did it all the time at 70mph when the motor was new.

The plan is to bench check them, if they aren't flowing good I was gonna send them to Trevor Johnson for re-porting. He told me he gets many ARE heads, and he improves every pair he's ever seen.

Not accurate.

Let's perhaps just focus on Lyle's motor and let's avoid the bandwagon phenomenon.

Quickin

At this point, that's another fear I have.

Im sorry to hear of your issues, Lyle...

The time I decided to stop sending my stuff back to ARE to be "fixed" and took it somewhere else, as costly as that might have been, was when my car started becoming fun again.

I gave MTI my heads to clean up and Im sure you've seen the comparitive flow charts. If not, I can always post them again.

I think that if you trust Norris, you are right to have them take care of it. Im sorry you had to go through all this just like alot of us others did.

I also feel sorry for those that still think that ARE was getting a bad name from baseless internet rumors and crap. You are going to go through alot more pain if you keep thinking that unless of course you can continuously drop your car back on their doorstep and say "fix it, I'll be back each day here to check on your progress."

I'm curious how MTI improved your flow numbers, can you post'em for me?
What kind of heads were them from ARE?

Thanks.

If the motor is coming apart sounds like a good time for updating the ARE heads. What castings are on the motor?

Someone got ~20rwhp gain when another sponsor fixed valve job on a set or at least that was what was posted.

A local car to me made 20 rwhp over ARE heads by swapping to TEA Stg 1.5's FWIW...

I have ported LS6 heads.
They will be flow checked and reported if need be.

325-330 cfm is what I'm looking for, right????

Visceral

iTrader: (1)

They were ARE's "stage 3" LS6 head. Supposedly the intake guide was moved over like .030 or somethign so it shrouded less. Couldnt tell if it ever happened...but:



Thats a pretty minor cleanup of the heads. I didnt want them to put too much effort into them. If they had needed serious work, I would have just bought new heads.

We could never get the car over 405 rwhp with the ARE setup and a MTI C1 cam. Now you see why.

Quickin

Visceral,
So 325-330 cfm is optimal for a big stroker, right?

Sir Sel

Quickin I have an ARE 436 also. I got mine pretty close to when you got yours. My Vette doesn't get driven much. Maybe a couple of Saturday's a month except for this past week, since one of my other vehicles hit a deer. The oil consumption seems bad. The check oil level indicator comes on repeatedly since I got the motor but since I drive it infrequently it hasn't been so apparent.

To be fair to all I've refilled the motor and reset the odometer and have scheduled a leakdown test next week. I will continue to drive it and report my findings to this forum and to Wade.

BTW I know strokers and h/c motors generally burn more oil than stock, but how much is too much?

I think the .300 to .500 lift flow numbers are the most important. The peak numbers are nice if they are 325-330 cfm but the most power will be in the mid lift numbers. I think of it like this: On a cam with .600 lift the cam will be at .300, .400 & .500 two times but only at .600 lift once. While the numbers above .500 are important the numbers between .300 and .500 are critical.

Check out this MTI flow chart for LS6 big bore

http://www.motorsporttech.com/c5_engine01.asp

.300 ~225 cfm
.400 ~255 cfm
.500 ~300 cfm

The key to getting the killer mid-lift numbers is the valve job. The port work is important but the valve job puts the flow at the desired lift etc.

I would also have the heads checked to make sure they flow about the same cfm at each port...ie flow balanced. Some Fubar stuff has had variances of as much as 30 cfm between cylinders.

As for the flow chart of the ARE vs MTI... ARE needs to get another sponsor like Patriot, TEA, GTP, LPE, MTI, RGR, Cartek etc with a clue to do their heads for them IMO.

that's what I'm thinking. My nitto's can hold my measly 473 rwhp.

gstama

My LPE 383 LS6 burns no oil.

mine probably burns a quart every 500 miles but it has no LS6 valley cover or PCV

Quickin

Mine burns 1.5-2.0 qrts every 300 miles. My bumper tuns black in 2 days of driving, I leave the most rediculous trail of swirling blue-ish/white smoke when I hit the gas and my intake and PCV hose are spottless from oil.
All of my oil loss is due to my rings. I know someone else with an ARE 436 and they don't burn any mesurable amount of oil between oil changes, they dynoed 497 RWHP/503 RWTQ (M6), so I know its possible to have a good one.

My ARE 422ci iron block did 475rwhp/505rwtq and did not use oil, and the rings were fine when inspected. If I did a lot of spirited driving or was at the track, I would use 1/2 or more of a quart just do the pcv system sucking it out. I typically ran my 422ci 1/2 qt over. Bores and rings were very good.

CHRISPY

PSJ made those numbers through an A4 and 9 inch right? That is 500+ RWHP through a six speed with stock rear.
