Great figures. Great build
 
Just interesting that you commented you saw 25 psi and running 22.5 psi ?
 
You definitely hold a world record there as the the most i have ever seen is 16 psi out of a C30-94.
Personally i think your gauge is wrong or not calibrated right, Because i got 251 RWKW's with 15.5 psi 
 
Dont know if you have already done so but do you have a dyno sheet posted ?
If not can you , ild like to see effects the cams you have on the overall curve 
 

Cngrates on the build.
240 in a Adub will be quite a experience. What is the weight of the car?
Is it for street or track work?
 

Boost is correct - in fact if would go to 30 PSI if we upped the RPM Limiter.. Rotrex and Bullex confirm this is quite acheivable with the C30-94. Boost is a factor of a lot of things - mainly the ability of the compressor to generate a given volume of air and the resistance of the engine to utilise that volume - The power I am making would increase exponentially if I changed the dished pistons to even a flat top forged, my compression ratio is a bit below 9:1, if I was to do the motor again I would be looking for 10.5:1, a smaller supercharger (C30-74) and max at 15psi .. that would make a better power and torque curve... nevermind ..
 
The car is a driver - not a track car. 

Well that makes sense, such a high  PSI figure would mean that there is a flow restriction post head or the engine cant use the air being supplied to it,
 
Yes i would have also increased my C:R also if i did it again 

Keith, can you post a copy of your dyno plot?
 
Would be good to see the power characteristics, still not sure on what setup I would choose when the time comes.  

I picked up a copy of the magazine yesterday, Well done the car looks mint. Must be very satisfying to see it grace the pages of ff&r. I'm a little perplexed as to why you left the suspension as it left the factory but i'm sure you replaced anything tired with new components.

Yes i would be most interested in the dyno plot also especially the Boost PSI versus rpm

Nicely put together car OZhummer

well don't forget mandaly, his engine is 25% smaller in displacement than yours, the efficiency of a 4age is nowhere near that of a beams, the port angles are nowhere near optimum for flow, with tvis removed, a bigport head is really ineffective at low airspeed. he also chose to run a factory exhaust manifold, so I don't find it that hard to believe the boost produced. I actually think it was you that posted a revzone power graph of a civic with the same rotrex charger making 20psi, so how is that hard to believe?

The dyno i posted i believe was the Bigger unit the C38-91.
 
For what its worth as you have said a restrictive system will produce more PSI but not necessarily power. The figures quoted seem to me somewhat high. Im curious to see the dyno and see where / how it got there and do a few calculations because as i said it would be a world record
