Your talking about the Hoppers Heads Reco Head - pretty good value if it works
FORD EA - EL FULL RECO HEAD NEW OVERSIZE EXHAUST VALVES NEW SPRINGS PORTED PERFORMANCE GROUND CAM (any wade cam) $ 1095.00 inc. GST Saw the add in Street Fords - Good Price for a claim of upto 175rwkw  Apparently 175rwkw was achieved in an EF Manual without a Modified ECU Just Extractors and Exhaust ACL Rebuild Bottom end though just to tighten it up......... Tested Car had a Wade Cam - dunno what profile www.hoppersheads.com.au

I'f they can't/wont supply that info, i wouldn't be buying it |

The Haltech Platinum can be spliced into the genuine Ford EF-EL PCM.
My co worker wired one last week into a EF TURBO at HITMAN'S workshop. Still using the idle control circuit. Waiting for power results.

You'll also need alot of compression and alot of revs, think 7000+. you won't do it on stock rods and pistons. lol ticky, as I was reading down I had the exact response formulating away. Ill second everything there, a tuned intake for high rpm, and a 6.5-7k rpm engine. power is a biproduct of torque multiplied by revs, so you need to make the engine produce more torque further up in the rev range, which is measurable by volumetric efficiency. An undersquare motor like our 4l sohc six has highest VE at about 3000 rpm iirc. which is why turbo's go so well on them, as they are pumping more exhaust gas low down than an oversquare motor, hence better spool up. the boost also benefits the undersquare motors poor VE characteristics at high rpm. you need to oversize the pistons, and strengthen the crank and block. its a big job. you are basically redesigning the whole motor.

i do understand that, this is what im trying to find out, what can i do to the rest of the engine to make its output closer to what the head can flow seeing as im going with this head i want to know what can be done to the engine itself to make more power.

I think they're quoting dyno figures from some of the engines they've built using the head and cam package. As mentioned above, the engines probably have ACL race pistons and other mods to get that output. I found the company good to deal with and they didn't waste any time getting the work done.

Why a 1636 even been mentioned in this thread is beyond me...
If you want this level of power it isn't as simple as getting headwork done, getting a rebuilt bottom end and then getting the biggest cam you can find...everything will have to be matched. I guess if you don't intend on building it yourself that's not a problem as an engine builder would know this. What do you intend to use the car for?

read the first page of what i have, it will be a complete rebuild, it will be used to drive but want as much power as possible with it still suitable to drive on the street, i can handle a lumpy idle but nothin like the 977b i dont mind the idle of the cam in this engine though
http://www.youtube.com/watch?v=cqR_ifA9rL8 does anyone know what cam it is, the specs dont show up on my computer

977b is a p***y cam, idles like stock.. bigger the better!
Cam in vid is a wade 1543b.. |

you know what the go is with mine. The cam going into that has 280 at .50. you should consider a good balance so you can spin it up higher. Power is a figure of rpm and torque.
You realisticly are looking at custom cam territory, nobody makes a cam that will work perfictly for you 190 is big power territory na for these things. We have done the maths on the computer program at the race shop and from what we figure on inertia weights on my internals, which are a fair bit lighter than stock, 7500rpm is very safe, 8000 is getting there for a race build, and self distruction, according to the computer is at 9100.

From memory the wade 977B cam makes more power & torque in the mid range than the wade 1521a cam but makes the same power at peak.
FordFairmont has used both cams & from memory he put the 977B cam back in his engine. According to Keith at wade the 1521a cam is a turbo cam. The cam i would be considering is the CamTech Cam stage 4 with 248 at .050 & 602 lift. That cam should power at 7000rpm & with a tight lobe seperation at 108 it will come on very strong with a rough idle.

I've spent hours and hour and hours with engine simulators fine tuning the mystical 200rwkw AKA 400hp at the fly engine. Based on a stock stroke and a 1mm over bore the lowest i could get the peak power was 7000rpm. Mind you we are talking big dollars to actually build that engine. you need to be careful throwing number around like that. People may get the impression you are saying 7500rpm is 'safe' (i hate that word in regards to engines) for a factory components. |

What i don't understand is why a crossflow can make 200rwkws at 5500-6000rpm and the ohc can't.. the only differences are the head and where the cam is.. people just don't seem to be going wild enough with these cams..

its all the ecu, needs to be more time spent in that part i think
