i was wondering if this combo was to much for a superram

super ram
AFR210 heads
ZZX cam 1.6 roller rockers
383 10:1 compression dished pistants
2800rpm stall
36lb injectors

i'm aiming for over 500hp flywheel no quater mile goals.. i already have the 383 built but the heads are poo so is the cam..

does that seem mismatched or to much for a superram.. if so what would be a better intake stealthram or miniram.. i was doubting the superram could flow enough CFM..

i'm guessing when i pull this motor in for emissions testing i'm going to have to fill the tank with alco run it very lean and pray eh.. or is this a case of no chance in hell?

 

The miniram would work a whole lot better with those heads and that cam. I don't even think the AFR 210's will seal with an aftermarket base manifold or with a stealthram. You could have the ports built up though. Emissions would be difficult to pass with that combo. Some carefull tuning and dry gas may get you close though.

 

I dont know about emissions, but that zz-x cam likes to spin the motor pretty high like past 62-6500 (probably a lil lower in the 383 but still way past 6000). That superram will cut u off at around 5800. Its not cuz of the cfm's but because of the long runner lengths.

 

.

 

That combo should work fine. You will have to have some material welded to the base to cover the 1206 ports though.

 

just for fun since i've never taken any of my cars to the track if it hooks i should be somewhere in the low 12's high 11's?

 

With a perfect combination and proper tuning, yes.

 

If you're looking for a drifer/street setup, go with the torque-heavy-down-low SuperRam (plus it's emissions legal).

If you're wanting more high RPM performance and willing to lose some low end performance (like on a drag car), the miniram or Holley SR are the better picks.

By the way, with Lingenfelter's TB the SuperRam will flow 1000CFM plus which should be more than enough for ANY motor...


Just my worth......

 

Hey, not hijack that this thread, but this is semi-similar to what i'm hoping to do soon. Would the general concensus be that the superram is a little better street friendly, low end power system? Leaving the miniram and HSR for a more racing, high revving application?

 

Super Ram is all about street torque.
It doesn't rev high like the MR or HSR but the seat of the pants feel of a 1-2 shift is AWESOME!

I don't rap my engine out over 6000rpm on a normal basis so the MR or HSR is not my cup of tea.
I'm happy with my SR.

 

Not as far as i'm concerned. The superram may be able to produce better low end numbers (under 3000rpm) but the stealthram and miniram would still fell pretty strong. They're all great systems and they all have there own +'s and -'s. As a superram owner i'm happy with what i've got.

 

The super ram does provide enough air for a 383...but thats not the issue. With its runner length, its only gonna make power to ~5800 rpm. The zzx is gonna make its peak HP ~6500 rpm because of its duration. That is a mismatched combo.

These guys run the superram with the zzx cam and also solid rollers and are running low 11's.

 

thats why i origionaly asked if the zzx cam is good for a superram.. it should be a mismatched combo but it seems to really fly..

 

I have seen a superram setup on ebay that was ported for 1206 gaskets at least he said it was. Running low 10's with his, with nitrous, but dont know that combo. Do you really need 210's for your combo? I think the 195's with competition porting would be enough. I also like the ZZ-409 cam (226/226 .520"/.520" lift) or something abit bigger like 230/230. Alittle less duration to help put the power abit lower in the rpm range like 5500-6000, just a thought.

 

well, how much hp would i loose by going with 195's ? remmber i'm trying to stay above 500 crank hp..

would that 230/230'ish cam keep me above that goal?

 

Not quite sure, but it may. Just a thought that a little less duration than ZZX cam would make peak power somewhere inbetween 5500 and 6000 where superram power peak is. The 230ish cam may be enough with alot of lift to with the ported 195's. The 195's with competition ported runners flow 280 cfm at .550 lift. The 210's race ready flow 277 at .550. The competition 210's flow 282 at .550" (293 at .650")

The 210's just surpass the 195's at higher lifts at and over .600" and more on exhaust side. Nice head if you want a cam with lift over at or over .600" lift. With 1.6 rockers, you can do that with cams with close to .550" lift with 1.5's.

385 miniram
This site may help. 385 miniram with 230/236 cam with AFR 195 made 480 on motor. With superram, you may need more air with bigger cylinder heads and cam, but the differences in the 195 competition heads and the 210's competition heads is that 210's will flow more with higher lifts at .600" and beyond and more on the exhaust side (like 12 cfm at .600"). The cam gots to have big lift to take advantage of the 210's big flow numbers. Exhaust side can be handled with either more porting or more duration if go with 195's.

You may be better off with miniram for more power but should be able to do it with superram. Just keep searching for other opinions. Miniram is very popular for big horsepower. Check this thread.

Oh, I seen a 86-87ish corvette with superram and 383 tuned by Ski down it running 11.30's with et streets and think 308 gear on a auto 700 with 4000 stall. Not sure of the power but had to be close if not over 450ish.

 

You may not want all of that torque on street tires.
I don't know the specs on a ZZX, but my current carb set up has an aggressive 243/251 @.050 solid flat tappet cam and 10.9 CR 383.
If it had any more low end, it would be hard to drive.
383's typically will have about 30-40 ftlbs on a 355.
From all the info I've seen, a SR will have 20-40ftlbs at 3500 on other intakes, but they will make up for it above about 4500.
Ski Down It swithed to a Super Victor EFI intake and lost almost zero ET on worse conditions last I read. Said he needed more gear to compliment the intake. So a "top end" intake will still be plenty fast.

With 2800 stall, a HSR etc might be a better setup. Depends on your gears. And a HSR is a lot cheaper than the others.

 

Listen to everyone act like turning 6500 versus 6000 is such a HUGE difference! Whatever! There is no reason a well put together lower end with quality parts can't handle even 7000 rpms on a regular basis, IMO. It isn't like we are talking F1 engine territory here (17k+)... And there is a reason why people looking for as much power as they can (more often than not) go to a setup that revs higher - its called a smooth and flat powerband that doesn't fall on its face right after it hits its peak.

Spin the damn thing a little bit - Miniram it with the ZZX and AFR 210s. You won't be dissappointed.... Unless of course you have to pass emissions, in which case I guess the Superram is your only choice.... But definately go with a different cam if you do. I think the ZZ409 (or similar) cam would work well with the Superram. The 210 heads will probably be a little bit of overkill as well if you aren't going to spin it but I don't think they will hurt you either as the AFRs keep port velocity up even on the 210s from what I have read/heard.

You might want to check out what Brodix has to offer in the head department as well....

 

yeah, i have to pass emissions but not a visual as long as it can pass the sniffer.. and i've had no problem spinning this thing to 7500k.. yes i know superram doesn't make power up there.
