Hallo i have a escort cosworth with new bulid engine.
s&j aloy true studd blokk.
148mm aroow roods.
92mm omega flatop with a bit valve cut out and coated.
the cylinder head have 36mm inlet and 33mm inconel valves and seat and wil hopefuly give me some good numbers.
and yes the car running 9:1 in compresjon and is only rwd !
the intake i have used earlier is a hart plenum with match portet runers/intake.

the enigine is bulid for high rpm and will be running a efr9180 so maximimum tork on low rpm is not my goal, i read alot about barel intakes and Mis but they are not that willing inn high power but beter to have for a longer rpm ranges?

sooo what alternstive is there? only use the hart plenum but maybe with spacer and ofcours 70mm trootle ?
hope someone having somerhing good advice to with becouse always good to heare other idees and experineces.
i like a good finish on thing to so good if its looks okei too! and a bit of engine just puttet togheter abit to see coolars and have ever bolt sent away 🙈

regards
