A hidden bonus of the Stealth's rear crossover is you can connect your heater hose fitting there instead of running the hose to the front 0of the engine.

I owe you sir, a steak dinner. I'm putting an electric fan on my motor and i was trying to figure out where to put the temp sensor. Now I'll relocate my heater hose to the back and put the sensor in the front. I can't believe I didn't think of that.    Thanx!

     I placed my Summit order today. I was tempted to stay with my Performer intake to save money, but I bit the bullet and bought the Stealth.

Hey there everyone...so I narrowed my intake selection down to either the Edelbrock RPM 7121 (or the AirGap 7521 as well) vs the Weiand Stealth 8020. They both look good and they both get good reviews from users...both aluminum...both roughly the same price (except the Airgap at $65-75 more) BUT ONE THING!!!

I found some pictures online of the Edelbrocks and it seems neither of them have the rear coolant crossover....where as the Weiand 8020 seems to have the rear crossover...in fact the Weiand site says it does and so does jegs and summit has pictures of it as well......

So I called Weiand to ask about this manifold on the Performer RPM heads and I ended up "fact-checking" just to check out the reliability of the tech guys information and he puts me on hold for about 6 minutes....then comes back and says that one DOES NOT have the rear crossover!? He said he just ran outside and looked at his car (which mysteriously had the underside of the intake clearly visible) and tells me that his doesn't have it so none of them do... WTH is this all about?

1. Does anyone else have crazy Weiand stories or am I only the only one?
2. What do yall think of the Stealth vs the Performer Rpm?


Hi,
I'll add, I've been running a Performer RPM on my street beast. It has the cross-overs. It's a classic dual plane and helps my junk achieve it's 392 RWHP at 5900.

I got my stealth from Summit last week and sent it back immediately. The casting was completely different from the old design. They have eliminated the rear cross over. Some of Summit's photos show the crossover, some did not. I called Weiand, and they say that the design changes occurred several years ago. I have tried to find the older casting. There is a gent on eBay who states that his has the rear crossover in the item description. The auction showed a stock photo, so I emailed him, asking him to email photos of the actual manifold for sale. He then said it would be drop shipped, so I explained to him what I have found. He hasn't replied, nor changed his auction.
Cheers,
Brian

I've tried all my usual sources, and everyone has only the Chinese casting. I'm probably going with the Performer RPM (not air-gap).

I did a search on Summit Racing last night. I've narrowed my choices down to these:


Summit Stage 3            http://www.summitracing.com/parts/SUM-226031/?rtype=10

Weiand Street Warrior  http://www.summitracing.com/parts/WND-8124/All/
 
Edelbrock Performer      http://www.summitracing.com/parts/EDL-2121/

Out of those, I like the Performer RPM the best. I do like the old design Stealth better than the RPM due to more flexibility of installation, but noticed no performance difference when I tried each on the same combo.
