Cut and pasted from Facebook.

This is the first testing of the NEW KRE Super Wedge Pontiac cylinder heads. This engine is a 541 cid with a 50 mm cam, STOCK / AS CAST KRE Super Wedge Heads with a 1150 Dominator. This engine made 926.8 HP at 6900 rpm and 777.4 ft lbs of torque at 5300 rpm. The dual 4 (1050 dominator carbs) combo made 937.8 HP at 7000 rpm and 785.9 ft lbs of torque at 5800 rpm.

927 HP seems quite high for 6900 RPM.

6900 RPM seems quite low for 927 HP.


Holy smokey!

Mark,
Why not? A 541 ci @ 6900 RPM @ 100 VE @ 12.75:1 and 930 HP would have a BSFC of .417. If CF =1.00

Maybe Alex or someone can give some more information on this pull.

Stan, yea, that 535 pull shows 929 HP at 6500 RPM. Sooo, i'd like to build and rev my 470 based on thaat. Can you PM me the recipe?!

[Aaron Quinton]

That can't be right, it's KRE.

KRETTF!

[slowbird]

It's interesting it only picked up 11hp with tunnel and 2 carbs, and peak hp rpm only went up 100rpm but peak tq rpm went up 500rpm

[Aaron Quinton]

Where are these results?

KRE Super Wedge

The engine was a thrown together 'mule'.

John, what does that mean" the engine was a thrown together 'mule' "
Are making excuses for KRE, why did KRE post if not their best ' mule ' engine????? 'One' of the things that bothered me about Jeff is, when he said to me, I can't get anymore out of these HP heads. So I suggested sending the heads out to a head specialist and see if they could get anymore out of the HPs, his answer was always NO. If KRE has a block or a set of their heads that run fast in someone's race car does it not STILL make KRE look good???
John, since you are the KRE know it all and I guess their mouth piece, well you and ken, WHO has the fastest NA door car with KREs HPs ?????
I did not post to crap on KRE because I went really fast with their MR1 alum. block ( thanks Bill Mellott ) and their HPs. Every other block and head manufacture gets more sales when someone goes fast with their products no matter who massages these products.
All us Pontiac guys have to thank all the Pontiac manufactures like, DCI, All Pontiac, Visner, KRE, for continuously giving us the products to SMOKE the chubbies guys.

16.1 comp too!

The heads sound like a really good opportunity for some builders.

Been waiting for this. Marcella need to get his hands on a set. High Ports started out @ 330cfm. Took them to just shy of 460fm. E heads start @ 280cfm, took them to 414 cfm. These start out @ 400 cfm, you do the math.
All the most impressive numbers come from same guy. Ain't bragging if its true.

But for all the rap KRE takes, this just proves they have brought to the marketplace more real Pontiac performance parts than anyone. And that was true before the Super Wedge.
Sure do have some long valves and some real long pushrods though.

450+cfm from a HP head is nothing new.
It would be cool to see what Marcella could with these Super Wedge heads.

True, but "cfms" are not cfms. Some peoples are better than others. Mikes E heads went 414 and made 1218 HP. I tried but could not get them. So I went for 404cfm heads by Gabby. Great heads, he was the first to get 1000HP NA with E heads, knows what he is doing. They made right at 1000 HP, depending on dyno. Sure, it was with NO2 cam and a heavily ported Victor vs a heavily ported BOP. AND 18-1 CR but two HUNDRED HP is a lot of HP.
I truly believe he has a gift. Can look at a port, runner and know where material needs to be removed to fill the cylinder.
If you look at just cfms those 450 cfm HPs should have made 1300HP NA, But its not about that . I just think its nuts that a "little" E head with factory steel guides made that kind of power NA.
BTW, High Port started off as a billet too.

not the first to make 1000HP NA w E heads: 900+ RWHP in 2007 John Bailey/Neal Owens/Slawko heads

[John Langer]

450cfm will NOT give you 1300hp n/a on top of a 565" Pontiac. Not even close.

[455firebird1969]

What intake was under that single carb?

[steve25]

Well if that was with them in stock 400 cfm form there making good VE numbers to top 900 hp!
