its fine, my friend boosted a dual cam zc with like 10-7-1cp and with a rhb5 at 14psi, with the afc hack, lol, he fried his ringlands, but if he would have spent some money to tune it, it would be fine...

i'll eventually be buying a wideband but for now I'll just be uploading a good base map so I can drive it to my tuner and have him tune everything, cam gear FPR uberdata all that ----, so it all runs right. So you guys dont' think there will be any problem driving 9psi daily, what do you think would be safe track psi on 101octane gas (I know I'm getting power hungry and I don't even have it on yet, lol) Also a friend of mine wants to sell me is NX N-ntercoler chiller kit for $150 should I get this and run it using CO2 or would that be over kill

And thanks for all the help guys Your making me feel good about this project I think I'll sleep alright tonight. Thanks

idk about the n-tercooler or w/e, might be ok, but worry about the kit first, id run 8-10 on pump gas, its fine, i ran 92 octane with a ls turbo at 11psi with a super 60 t3. just make sure its tuned good and what not, dont boost high with just a basmap, get it tuned asap, or u will have a good chance at a fucked motor. just get it tuned, run 8 daily and 10 at track, pump gas will be fine, but race gas is always better

IMO those maps Leed posted have way too much timing for that setup. I have a lot of experience with my own y8 setup i had and they can't take timing like z6's can because of the combustion chamber design the y8 has. On my setup with a small wrx turbo on 8-10psi it would slightly ping with maps very similar to what leed posted. Eventually i plugged in the actual p2p y8 timing maps(which run way less timing for a reason) and i ran about 12.5* total timing at 10psi with no pinging. Even if i had the timing turned down as low as 15 or 16* it would still ping. This is with an afr of 11.5:1 in boost. For your setup you will probably need even less timing. I would take this to the dyno for ignition tuning and keep an eye on your plugs!

Yeah it will be going to the dyno a few days after install, but I still need to get a basemap that will get the car there. This place is 50miles away and I don't have that kind of flow for a tow.

for your basemap download bigwig's p2p import script for uberdata and import the p2p timing maps in. Use that as a start and not the p28 timing maps.

So I should just use a stock p2p map i mean I could just run my p2p ecu till I get to the tuner. Or is this a p2p map that is more for boost and 450s

Also my goal on this project is 220whp which I don't think I'll be at but do you think I'll be over 200

you need to import the p2p map into uberdata. http://uberdata.pgmfi.org/forum/inde...;threadid=3407

Which is completely different from a D-series - those guys are using boost to pick up where their torque curve normally drops off so they make mutant high rpm hp. They don't build lots of mean cylinder pressure to create power, they just rev to the moon and let the extra rotations take care of the problem. D-series have lower torque, aren't as efficient in the higher rpms, and that makes them a completely different story.
