thats why i am 12.5:1


Its not all about port flow to spool a turbo, its more about volume, displacement, compression, and fuel. Not really how well the port flows.

Im debating on bumping the compression up to maybe 10:1 but im not sure. E85 and e98 also have a much higher energy displacement which helps. But not all are running Ethenol.

A ve head flows pretty good and the couple cars in az that used this turbo were 1.9L 11.5:1 cars with semi ported heads that probably barely if that flow the same as the VE head. We will see, Im probably just gonna stick with 9:1 as I dont think i will have an issues plus im using the smaller 1.10 housing.

All I need is to make full boost by 7k and that will give me what I want. Because I dont mind reving out to 10k, VE's will take it all day long when built right.

You!!! have a very high spirit, ahead of the crowd you should meet the goals you are looking for( i hope ), your seat time and knowledge should take you their as for spooling, with your head setup and rpm limit you chose.
spooling is the last thing you should think about, more like putting the power to the pavement 235/60/15 or 275/50/15 <--- if you really cant catch

Coheed learned to rev his out, VE's love the high revs and with a properly sized turbo and proper cams, watch out.

I have a feeling he will do good. He just might need to tweak his plans a little but he's on the right track.

And what would you recommend as far as tweaking goes.

I'd love to see someone switch me over to a No Ass car after being boosted for so long...

I would go with at least 10:1 compression. Now a days that's considered good for boost. If I had to do another engine I would go that route instead of 9:1. You have a stand alone, make the best of it.

Only problem with that is CP only makes off the shelf 9:1 and 12.5:1 pistons for the VE so it would be custom. I was debating on going 12.5:1 and it would probably work really well with the N1 cams as it would lower dynamic compression and help spool the turbo but is it really worth losing some of that forgiveness of the lower compression pistons for the extra response and quicker spool. Thats what im currently trying to figure out right now. So yes some changes may be in the works but we will see. 12.5:1 is common in the big hp turbo honda world these days.

Theres alot of other changes that could go right along with that such as running E98 methanol as well but would require even more expensive upgrades to my fuel system and my fuel pump choice. So Im trying to weigh options here.

E98 has very very good energy properties that greatly help spool time as well.

A lot of this hasnt been tested back to back. Because then theres the if i go with the higher compression and E98 should I switch or test the 1.10 and 1.25 housings for the BW to see which best fits my goal and makes the best power safely. Definitely lots up in the air right now. Im just continuing my research on the matter and will go from there.

With e98 you would def. have to upgrade your fuel system. All of my friends down here run it on their track cars with great results. You could add 4 more injector and trigger them to kick in at a certain boost level. With a standalone you have many options.

Yeah and dont know if its worth it over running tried and proven C16, We are talking an extra 800.00 in pump upgrade and -10 line, another $500 in injectors or so. So Im thinking its not gonna be worth it for what im trying to do. Still up in the air about the compression and waiting to hear a couple more opinions on it before I make the decision to either stay with 9:1 or go 12.5:1. Im thinking 9:1 is gonna be my final choice though from the few responses Ive gotten.

Yeah 12.5:1 is a big jump from 9:1.
