Well fellas remember in history when Galileo said that the earth revolved around the sun and was arrest for saying that, well watch this video of a STOCK block 8th gen civic with the TVS1900.
When displacement and compression are ruled out, look to the head and valvetrain.

There is a very big difference between the K20 head and the Ecotec LSJ, LE5, LNF, and L61 head.


Our valves are considerably smaller, in addition to a inferior head design.

You can port our head as much as you want
Use which ever valve springs you like
Run any cam combo you want

End of the day... you're not touching a K20 head if you're still using stock valves.

Do you know what PSI he was at by the end of the pull in that video? That will give you the answer.

19psi through a Honda head is a fuckton more airflow than 19psi through an ecotec

Now plug 19 PSI to the TVS1900 efficiency map
2.3 PR

Need to know the pulley size, crank pulley diameter, and engine RPM.

(Engine RPM X Crank Pulley Diameter) / S/C Pulley = S/C RPM

What about forged pistons with a higher compression? Could 400whp be possible on pump?

you are 100% clueless there is big difference between a k series head and an ecotec head the amount of air they move is stupid compared to an ecotec head and then they have the best valve train setup out there and no lash adjusters and the ones in the ecotec head are garbage you need to dig deeper before you run off at the mouth about another platform making power

But in theory wouldnt the 1900 be better because it can be just as efficient as the 1320 while spinning slower producing less heat?

OP if you are seriously interested in the 1900 and info on it then I may be able to help, Inbox me. I didn't read the entire thread but generally speaking Steve(100% METH), Anthony (Advise) & John(Mr Belvedere) know their **** when I comes to the supercharged LSJ's, several others in this thread too but I'm not gonna list everyone individually. I am also getting ready to put my TVS1900 setup up for sale. I bought a G8 and the Cobalt will be either returned to stock or converted to a 1320 setup so it can assume DD duties.
