I have a rear mounted RMR intake manifold, I think you under estimate the amount of air the head can flow in stock form, do you have pictures of how you ported your head?
Most people ruin the flow of the head with inaccurate and inexperienced headwork, I never said headwork was unimportant, I said it was not neccesary for power levels under 600hp, proved many times on many setups.
What are the specs of your engine, 800rwhp is alot to put through the motor reguardless of how much headwork etc you have, even the 2.2 blocks are not strong enough to handle consistant amounts of hard driving at that horsepower, block girdles, sleeving them, filling them with concrete and other stuff to stop cylinder cracking and distortion just doesnt cut the mustard when the engine is that highly strung.
I dont understand how alot of people always use the airpump terminologyand then stick to a 2 litre platform with a massive turbo, if getting air
"through" the engine is so important then heres some more terminology
- theres no replacement for displacement.

(so recon ats racing)
no idle problems, sounds LOVELY to..
idle is at 1400 tho, lol.

How does it idle at stock speed, like 950rpm or whatever? 1400rpm isnt idling really is it lol
My car idles ok, but it idles really smooth at 2000rpm lol

This is the flow chart for the head if anyone is interested.![]()

Paul@ Kent Car Craft, your rev2 head will not be helping your cause when it comes to power.
If i were you id send it off to have cams and headwork for your"couple of K"
You don't need oversize valves, but an excellent port/polish and inlet flow matching will do great along side some"slightly" wilder cams.

Companies worth their salt will not just port/polish an inlet but polish it then sand blast it slightly as mirror surfaces(they look nice) makes the fuel stick to the inside of the ports and you lose power.
OR just go to a REV3 head if you can get it to fit into your budget.

1.5litre formula one engines last one race lol, put in in an endurance race with a v8, v10, v12 NA supercar and see which one lasts the longest, I know where my money would be,
I dont think the head is the most restrictive part, the most restrictive is dependant on your setup, fit a ct26 to your motor and no ammount of headwork will sort that out
I dont think there is anything left to prove with the 3sgte engine.I could go in my garage now and build a motor with block girdles, solid liners, filled block, 1 million cc injectors and a turbo so big i cant fit the engine lid on anymore, it might make a hell of a number and maybe pull some good drag times but how far do you want to take it.

I built my own car..

from a shell, the only thing I have not done is machined the block and head.
I have put a car together that i can start on a morning, and drive all the time, it has made over 400hp since its first dyno at 500miles and has now done 13k miles of hard reliable driving and now its going to make more power and still drive everyday.Now thats more important to me than a big figure.
Ants car is a awesome piece of kit, because of the attention to detail he has put into it, i have never said theres anything actually wrong with tubular manifolds or dual rails, I said I dont like them.Personal preference is what made my car what it is.
Jim: Try turning the idle down on your commander and see what it stays smooth at, anything under 1350 for me is a bit rough as I have solid mounts on the motor.
