good luck spooling that beast!!5 stages of nitrous should do it...one for each gear.....hahaBTW comparing to a gas Civic isnt fair...those little bugger have lots of RPM's it get that turbo wheels spinning.post your progress as you go ed!
maybe find a different turbo to spool the hoslet?
Your idea looks a bit too bluky for the this head (IDI) its tight enough to use 1 o-ring!Also if you look at the pics of my head you would see that we had to machine around the prechambers which could not work with your idea but Your idea would work on a TDI. Part of the issue with sealing the head to block is due to using a turbo(s) that are not proprely sized which leads to high turbine inlet pressure preventing the exhaust from leaving the cylinders thus increasing cylinder pressures and raising combustion temps also.The hybrid hx30/hy35 still won't cut it with 29 psi boost/32psi drive pressure and EGT's pegged the whole time.I'll be putting an hx35 compressor onto the hx30 turbine next hoping that is will raise boost and equalize drive psi/boost pressure,Any thoughts?
The head is just not up to the challenge for these high hp IDI's.The coolant ports and pre chamber are the week spots.We would need 6 head bolts per cylinder to have any hope of keeping the aluminum from flexing.All 4 cylinders are leaking so an intake manifold will not fix that.Daves setup is completely different to mine his engine has smaller pistions (1.6) and has a big single turbo making much lower torque and HP than my setup.With the compound turbos my engine produces lots air flow at lower rpm and having bigger pistons ony helps push the head off.The last dyno 2 years ago my engine produced 161 whp @ 4250 and 225 torque @ 4000 on only 30 psi and 86cc's fueling and no head or gasket issues.Now The fueling is 120cc's boost is 50 psi the engine now pulled well past 4500 RPM you do the math?
Sad day for IDI, two of the big ($$$$ and Time, R&D) motor's are dead, and will not be revived. In the light of this I'm putting a celling on IDI power at about 200hp. Both of these cars produced ~200hp but neither could live for any length of time with it.So for everyone pushing for a powerful, reliable, IDI I would call it quits at about 170. If you are down for the $$$$ and time it takes to push the limit, absolutely I applaud your effort.
