So our you saying there is going to be a problem with my compression with this turbo set up...

Also what would be a resonable amount of power I should expect from this setup at 9psi. I'm really aiming for the 220whp mark

 

he's not saying there will be a problem, he's just making sure you knew that guys statement didn't have alot to back it up, like logic.

9psi on my z6 feels like about an even 200-210whp or so on the butt dyno. and i have a mildly damaged piston in cylinder 3.

 

**** how long did you run this setup on your car? I'm going to be starting another motor build this winter probably around october, then turning the boost up to 16psi and running a direct 75shot from Nitrous Express


Eventually looking for 300whp right now 220 is my goal

 

No, I don't think 10.3:1 CR is going to be a problem, I just didn't want you confusing B-series VTEC with D-series. The amount of cylinder filling, and the amount of load, taking place in the midrange of a D-series is quite different and will need a richer AFR for safety than the "12:1" "ideal" AFR for the B-series stuff pushing your power levels.

With the 14B, 200 whp is no problem. 220whp should be safe if you have a good sized IC but you're getting close to running out of turbo. Plenty of HT kids have hit 300-330 whp, but you'll need a bigger turbo and a less restrictive turbine (.50 trim T3/T04 with .63 AR stage 3 turbine is popular) and headstuds and misc small stuff. You can keep the more restrictive turbine with water injection, which does a lot more for taking heat out of the engine than an IC, and enjoy the quicker spool, but some people don't like the complexity and always having to fill the water injection reservior.

 

Well I'm not down for the water sprayer, but my buddy has a Nx Nterchiller kit that he is willing to sell me for $100, i was thinking of just running co2 since it's much cheaper the nitrous oxide, do you think this would be over doing it

 

I didn't say water sprayer, I said water injection.

Spraying anything on your IC is a ****** half measure that renders minimal gains. Pick something juicy and spray it into your engine - ah!
