I have a JRSC at 8psi, and may spray a 15 shot. People tell me I will mess up the motor by not having adequate fuel in there, not because the block cant handle it.

So what can a dyno tuned stock c1 block hold?

 

i saw a civic hatch, with a JDM B18C1, turbo charged, only running 8-10psi of boost. this car put out 311 whp, on stock internals! its all about tuning. the car eventually went to the track. it ran a 12.7 on street tires at 120 mph. it actually hit the JDM speed limiter before it got to the end of the track.

 

There is no magical #.

When you get your setup complete, and you take the car to your tuner, he will tell you what you can squeeze out of the car based on the conditions at the dyno. No two cars are the same.
