408 LSA build 408 6L
dished pistons 11cc mahle
monsterHeads (boost monster)
forged Crank
Cam: May use the tSP Cleetus boost cam
LSA probably ported Kong X port
TB: (unsure) looking
fuel rail: (unsure)
Fuel pump : dual walbro 525 hellcat
injectors: unsure
-
My goals are 800hp + reliable. Not street driven. Mostly dirt miles
i believe Ill be fine with ported LSA
Looking for cam suggestions or if I should try to save for the 2650?

You'll make 800 with the X port.
You're gonna want the biggest TB you can fit.
1300cc injectors
As for the cam, get something that's made for a PD blower, not a turbo(s). I'd talk to Greg Kong and see what he suggests.

thanks .
I was recommended the stage 3 or 4 from Greg So Ill go with 4
i believe I have a 102 laying around, which would help with costs.
That's a good jump in power capabilities from a 1.9L (even ported) to a 2.65L however it will be a lot easier to hit your moved up line in the sand of 950. Only took 8 days to go from 800+ to 950 lol. Although in your defense, 950 is in line with 800+
The 2650 should be nicely matched to 400ci+ as mentioned you would have had to really spin the 1.9 to achieve the similar results and with the 2650 you'll have a little more leg room left if you want.

Thats the deciding factor
Ported 1.9 or 2650
Of course I would send the used s/c out for x port upgrade

Verdad Gallardo You misunderstood.
408 + ported 1.9L you will still need to spin in it fast to feed that displacement thus you will start taking the supercharger out of its efficiency range. Even though I believe the 1.9 doesnt mind being spun pretty high you are starting to ask a lot of it. That will however create more inlet heat which leads you to have a serious heat exchanger setup in place to combat inlet air temps.
408 + 2.65L will not require as aggressive pulley due to the larger displacement moving more air throughout all of its rotor speed. And even more so when rotor speeds starts to get faster it will move more air efficiently.
It really comes down to application and matching blower to displacement which then gives you a better idea on power output to get to there. Im a drag racing guy, so knowing my weight and ET goal I know what Id need to move towards for power output.
