awesome topic which I enjoyed last week during my holiday... at home. Fantastic to read about 140hp per litre from these engines, incredible work and lot's of respect! I was already happy with my 1192 36hp engine putting out 48.9hp, but now I am wondering... with some clever blueprinting what is possible with that pre war design engine and modern thinking...
Anyhow any updates on cool projects?

Jpm single valve springs plus scat inner spring
Cromo puschrods
Cb H-beam rods 20mm pin
TCS20 engle camshaft, stock rockers 9,2:1, 102oktane fuel
Nothing real special on the engine intselfe
225hp@6800rpm 260nm@3500rpm at 1,35 bar
250hp@6300rpm 293nm@3500 rpm at 1,8 bar flatten to 1,6bar

Hi Chris,
Thats pretty cool. I 'think' our (UK) street best is Shell 98.
Really like your exhaust. It looks like you have paired the cylinders front & back to give 1+3 & 2+4 cylinders and then 'siamised' them together to keep the gases separate to the twin scroll entry, correct?
Can I ask where you have the water/air radiator? Is it at the front of the car and do you run the water pipes inside or outside the car?
Cheers
Marc

The tcs20 just matched my ports best. I wanted a range from 3500-7000rpm cam and port can do this. On the track i have fist till 8000rpm,
Sec. till 7500tpm and 3dr into finish line close the max hp.
98okt fuelnis std best fuel here too, but you can buy schell 100oktane and aral untimate 102oct. Fuel.
With the header its right. Because og the shape of the inlet into the turbine i build the true header with a friend exactly how you told. 4-2 and 1-3 and put a plate into a pipe to get all matched.
My whater tank is unter the back seat, pump is close and outside and radiator in floored under the car. Its ok. But not best solution.

Nice!
Im intending to see if I can get 2x coolers up the front for water and oil but had been considering only a water circuit . Then using a water-oil oilcooler sandwich adaptor. The water circuit would then cover turbo air-water intercooler, turbo water cooling and oil. That sounds like it would help with rapid engine oil warm up however I have a feeling that the water in the cooling circuit would only go as low as 80-90C and mean that the turbo intercooler wont be able to get the 'cool' air any lower than that temperature?
Would anybody agree/disagree with that?
Cheers

I run a TCS30 on my 1600 Challenge engine - unporteded heads and original valves and it produces 312 Wheel HP@ 2bar (29PSI). When I ran my quickest pass, I ran 2,5 bar (36PSI) on gear 2-4.

Is there a tuning reason for using 36mm venturi's in 48IDF's instead of using 44IDF's?
I'm thinking better signal, or maybe the 48's were available?
