Reformulated post:

I like to have a cam suggestion for 170 cu in slant which will have sequential injection and stock compression. Boost estimation 0,5-0,7 bars. E85 fuel only.

Behind of the 170 cu in slant will be 904 with high stall converter (3500+ with naturally aspirated 225) and 7,25" rear with 4,10 gears. <= These parts I will keep

I have an Oregon cam with 236/230 (0,050") degrees. It has been surprisingly smooth in street use.

If not better recommendations are come I will use it. But if a good turbo cam suggestion comes I will try it. Would be nice if it runs from 2000 up and the high power range is 3000-6000.

Monology continues:

End of season. Plenty of 15s timeslips. Two times 15,3. A batch of 15,5-15,6 times. Worst was near 17 but it was fun ride. Slipping finally stopped at 3rd gear going on.

139.5 km/h at the end. 5500 rpm. Cast pistons. How much I can go up with 225?

I tested my 225 today. Was running happily at 6500. Probably my cast pistons can do it every this and then.

If I keep my 225 as is and add 0.4 bar boost I probably reach 13.6-13.8 time with 160 km/h trap speed @ 6300.

This is my way to do it.

I will order a t3/4 turbo and add it on this engine!

I keep my cast piston 225 engines at 6000 or below, but maybe you will be lucky? Thanks for the report and keep having fun!!
