FSPP Aluminum Head - 11-4 UPDATE

I talked with the design engineer again today. It's finally done. :party:

Now for the good stuff, or at least some of it.

We were shooting for 65% on the exhaust flow. He hit 73%. :party:

The design will work extremmly well N/A or with boost, and is prefectly suited to a roots style blower. With the high velocity ports, fast burn chambers, 192/144cfm @500, excellent quench, 11.5 CR capability (n/a), and 100% fuel distribution, this thing is going to be Awesome. :shock:

We should be able to start the pattern work late next week and are shooting for an early to late spring release date. Once the first proto type is produced and we verify the flow numbers, I'll release more info on the exact numbers. All I can say, is if you install one of these, you'll need to invest in a set of street drag radials, not to mention an upgraded exhaust system (2.25" dual outs - mimimum, 2.5" is recomended). Bottom end torque will come on fast and strong and will keep on going thru mid range into the upper RPMs. He NAILED the design and exceeded our original specs. I couldn't be more please with the results. I can't wait to dyno the fisrt head, which will be videographed and put on a C/D.

With all the other parts we are working on here at SEMA, I think 400HP is very doable and 600+HP (with massive amounts of torque) may not be out of the question, with the right components.

We still need to get the 4V intake designed, but he is starting on it next week. But the intake is easy and fast to produce, in comparison.
 
I think this answers some of my questions in the other thread!

11.5CR seems a bit high for a roots blower application, but I'm assuming you mean that's what static compression this is designed for? Since I won't be in the Maverick I6 market till spring, this will be excellent. For a newbie like me, this gives me a lot of relief.
 
well is a prototype gonna be ran on a motor or two for durability issues first? IE I am concerned about cracking. could a sacrifical head be produced and purposely ran on a motor until it overheats to see if it will split like pane of glass if it gets hot (250* range) I would really hate to drop $1500 on a head and have it split the first time it got a little warm (IE fan doesn't kick on or T-stat sticks)
 
that compression is great for N/A but like mentioned seems a bit High for boosted applications. Will a shim gasket work to lower compression ratio but still take the boost?
 
I assume the 11.5:1 is going to be with your new .020" head gaskets? or is that with it decked some? I would prefer something around 8:1

:shock: :shock: :shock:
Amazing numbers Mike, to say the least! This stuff gets :twisted: by the minute!
But with this kind of HP what's gonna happen to the bottom end? What mods are necessary?

wow i am amazed it looks like i have to get a job so i can save up enough to buy one of them heads


just 1 question with the exhaust needing to be atleast 2.5" diameter will u be coming out with another header that would be an 2.5" outlet
 
How times have changed...

I might actually do something worthwild now ;)

I always knew the power was in there, but lacked the facilities to bring it out.

I assume it will fit a 250 or 200 ?

91 is highest octane 'round here
 
73% is a VERY impressive number for a non-crossflow head. I would love to see what this thing does with triple weber 45 DCOEs, a good solid roller, and a computer-controlled ignition.
 
The 11.5 CR is just what it is capable of supporting without detonation issues. It doesn't mean you have to run that much compression, only that you can. Safely.

We are going to add plenty of meat to the deck, so the head can be run with 8-8.5 CR as is, with thicker head gaskets. Or you can mill it and use thinner gaskets to get it up to 11.5 if you want. And still use pump gas.

73% is awesome, considering we maintained the stock exhaust pattern. The engineer was amazed he was able to get it up that high, as he didn't think it was going to be possible. Add in the high velocity ports, fast burn/high quench chamber design with 100% fuel distribution. :shock:

We will be producing several prototypes and will be running them to death on a dyno. We want to know exactly what it is capable of, before it goes on the market. When all the dyno testing is done, we plan to produce a C/D with clips from all the dyno runs, graphs, flow numbers, etc. We will also test it with various combinations of cam profiles, and induction setups. So all your questions will be answered in detail, before you buy.
 
Sounds like you are going to have this up just when I'll be needing it for the Comet's 250. 11.5 CR with an aluminum head sounds juuussssttt riggghhhtt said Goldilocks when she found the FSPP head. Keep those updates coming, looks like I'm a definite customer for one or two.

That is too sweeping of a statement....

1) At what octane?

2) as corrected to "standard day" conditions, or at sea level, or in Denver, or?

3) At what coolant temperature?

4) At what Air/Fuel ratio?

5) At what timing specification?

6) With what piston shape?

7) etc....
 
Those flow numbers compare favorably with the Ford GT-40X small chambered heads for a 302! That's one hell of a lot of flow on a 200 and enough to support a very, very strong 250. I'm suitably impressed.
