Recommended 408ci compression
Srk gets owned by me. You get owned by me. You block my comments because you have no answers for your junks abysmal performance. I show no respect to those idiots because they don't deserve it....just like you don't. You're to big of a ***** to even read someone's comments but yet will make comments on them......nuff said
I don't want to build a turbo motor. But if i were i wouldn't lower the cylinder pressure just to raise it again. I mean i guess you think guys boosting gen3 coyotes are complete idiots with them having 12.2:1 compression.
Of course he won't see this because he's to weak minded unless someone quotes it.

What turbo are you using on the 408? Aiming for a smaller or larger cam?
Keep backpressure in mind, generally with higher backpressure you get away with lower timing. Run too high of compression and won’t be able to run much timing at all on pump fuel. Combine those and you run into limitations on power before reaching your hp goal. I’ve run 20psi on an 11:1 engine on pump but timing was in the dirt and it also wasnt 1200hp. Engines in the 9.5-10.5 range seem to do very well in street cars with higher boost goals.
If goal is truly 1200hp I would look into at least a meth kit or a way to get e85. You can certainly get away with higher compression on E85 as well.

Hello sir.
you engine is 408ci?
10.5 compression ,Is the computer easy to adjust?
Because I use 98 fuel, I am afraid that it is not easy to adjust.
so 10:1 compression ok?
Thank you.

There's no reason you can't if you spec the combo right. Let the boost do the work instead of the compression ratio. If you're able to, add a methanol injection kit for some margin. Hio just wants to matter so badly on here he comments on stuff he has no clue about. Ask if he's built a 12:1 turbocharged motor on pump gas. I block his comments and only see when someone quotes him because he's literally been laughed out of this section for spewing garbage. Even the SRK section is fed up with him. He shows no respect, so he gets none.
ok.This way I understand.

Ya, why would a guy that can’t keep motors alive NA and make milk shakes under vac be in the FI section?
Tell the class about your 4 NA motors you’ve wrecked running low 11s and your blower fox that can’t touch a 10. Lol

Nobody cares how fast anyone is NA, thats just an excuse for why you lost and couldn't build a faster car. From a quick glance it looks like islander is 4 seconds faster then you’ve ever been and that’s all this forum cares about.
