weiand stealth intake vs Edelbrock rpm intake
 
weiand stealth intake vs Edelbrock rpm intake.I have a weiand stealth intake on my nova.Will I see any performance difference with the edelbrock rpm intake?I have a edelbrock 600 cfm carb.Thanks bm

not likely much differance, if any

killerformula 10-08-2004 02:24 PM

weiand is an off idle intake and is shorter. I'd bet it makes better power, overall.

killer,
what does that mean.....off idle?thanks bm

killerformula 10-08-2004 02:34 PM

power band on the stealth starts at idle, the performer RPM doesn't advertise power until 1500 RPM and later-

Thanks killer!!!!

I agree with killerforumla, from my experience the weiand stealth is a better overall intake.

I bet the RPM will make the same bottom end and top end as the Stealth. Some single plane intakes will make the same bottom end as an RPM. A lot has to do with your engine combo. The 1,500 to 6,500 is just a loose guidline.

I'll take that bet lucky.
The Stealth is better from idle thru 6,500.
The other thing is the cam specs on the rpm range to make power early. Some singles may make the same power as a RPM intake but not off idle. I would rather hit it from idle than come off at 1500 rpm from a stop light. All in combination of the complete car is a must not just motor.
None of these are close to off idle responce.
Performer RPM™ Manifolds (1500 to 6500 rpm)
Torker II® Manifolds (2500 to 6500 rpm)
Victor™ Series Manifolds (3500 to 8500+ rpm)
I would preffer a Holly Contender to any of the above intakes.
Idle to 7,200 rpm with the same air flow as a single and better responce thru the rpm range, gasket porting will bring up the rpm range up around to 7,700 rpm and a spacer plate can even help more if needed in tuning for that application.
My .002 cents worth and .5 bet.

the RPM ranges that the manufactures claim are estimtates at best, get you in the ball park.a Performer intake is advertised from idle to 5500 RPMS for example, if you put it on a small motor like a 283 or 289...itll make power well past 5500.
The Stealth is a good intake, Wieand claims the Stealth makes power from idle to 7000 RPms, while Edelbrock says 1500-6500. Sure, the Stealth well run below 1500, but realisticallythe 2 are probably pretty equal.
now...pretty much any engine that is making power to 6500-7000 RPMs is pretty dead below 1500-2000 RPMs anyway, so it really doesnt matter.
If your running it to say 5500, the Stealth & the RPM will make better power from 1500 RPM & up...but a Stock or Performewr type intake will make better off idle to mid range power.

To bad most magazines are closely tied with Edelbrock or we would get a dyno test comparison.

1BAD80 10-09-2004 02:55 PM

The manufactures claim are estimates at best. FALSE !

All the math modeling and flow test are done at all the manufactures, more than one way at that.
I guess they should throw away the flow test machines then. Their tested the same way as a head for flow.
I wish I could guess that close.
I made flow tester's for the oval one on the V8 back in the 80s and could measure the size of a BB difference between ports.
Even Flow must be controlled for all the cylinder's, this is the job of the intake. :drunk:

OK... maybe poor choice of words...how about individual opinion.
what one company calls a power band...or the way its measured may differ from another. Im not saying anyone is bad.
Simialier to camshaft companys, advertised measurements dont mean much cause they can make the advertised #s look in there favor.
You can have a grind from 2 cam companys with nearly identical specs...same centerlines, slight variation in duration/lift...but they claim to have very differant power bands.
as far as the Stealth intake, it may have good off idle numbers with a large cube engine...& great top end numbers with a small cube motor...but its give & take hard to have best of both.

1BAD80 10-09-2004 03:42 PM

stepside454, I agree with the similar to camshaft company's with the same grinds, the lobe circle may vary a little to come up with some of these numbers. I have done the same thing with the different company's on basically the same cam and the rpm range is different.
I don't want to change the subject on this posting. But it is interesting on the grinds. :thumbup:

don't take it personally guys, george just hates edelbrock lol.
