But I'm probably gonna be running an OBX ELM (I like cryptic acronyms) and a full 3" exhaust...from what I got from that dude had a funky log manifold and a ????? exhaust.

I really don't see how the pressurized intake charge can "push" out the burnt exhaust gas...in an N/A engine the scavenging effect helps the exhaust "pull" the intake in, but the restriction of the turbine on the exhaust would make the exhaust gas look for the path of least resistance, which I imagine would be the lower pressure/temperature intake charge. The turbo is not "pulling" the exhaust out, it's impeding it. Overlap would make the exhaust "push back" on the intake charge...I doubt that would be conducive to making power.

Bah...

Man, air automatically flows to the area of least resistence(pumps the air thru the head).

I can give you links to several F22 turbo builds that are easily kicking out 250-300 whp and over 200 wtq on FACTORY motors seeing 10-12PSI. The thing you should keep in mind is the displacement advantage. When the little tiny D-series is maxxed out to get those power numbers, the larger F series still has some room for improvement. This is also assuming that it is an un-modified D-series compared to an un-modified F-series.

Put the same turbo and parts from the Civic on the Accord (but with larger injectors) and with the proper tuning, it should kick out more than what the Civic did. Civic's have just been the "preferred" car to modify for so long that it's had more of a chance to "evolve" more than the Accords......but we aren't too far behind now.

And it hasn't been mentiond yet and doesn't have a huge impact on un-modifed trannys, but gearing of the trans GREATLY affects how much power is put to the wheels and when that power is applied. Don't most D-series trannys have shorter gears than our old F series?

I should know I got spanked by some civic coupe wit a turbocharged d16.I heard the sohc vtecs are better for turbo setups compared to the dohc ones.Don't know why.

Ahhh there's a 272 turbo grind...cool. You're making like 220ish whp too, right? You have the big 16G setup @ 10psi...I remember. Do you think you can get some more power or is it tuned and everything?

that dyno was way before the cam.

that dyno was way before the cam.

Did the cam make a big difference?

it seemed so on a butt dyno lol...but i didnt get to hit a real dyno delta claims between 12-15% gain to the wheels for most turbo setups. definetly worth the money !

first of all the d series cant produce enough torque to pull our big ass cars. i have a buddy with a carbbed f series with a cam and a milled head in a crx and it hits low 10's
