Give it some jandle, fuck yeah!

so what do you recommend for safe max power goal for an unopened stock FD motor with 3pc apex seals????

my personal goal is whatever I can get with a 1.15 ar p-trim with a gtx35 compressor at ~28psi... too much?

Oi Rice,

If you were to use an oil return scavenge pump to allow low mounting of a large turbo like one of those s400s (like really low touching undertray in front/besides engine), would there be enough room in the engine bay to high mount a s300 turbo pointing backwards tight next to the block, feeding (in addition to "primary" wastegates) into one of those s400 mounted low in the bay at the front with dump running under the exhaust manifold/smaller turbo? Would be nice to run 36psi from, what under 4000rpm to 9000rpm, I'm guessing due to the wider peak boost range you would want to run 2 stage pre turbo injection with a 50% flow rated secondary injector to come in before peak torque?

apart from all the obvious 'issues' its a great idea, I've done allot with Diesle's in truck racing (2 stage) and pullers running 3 stages, water injected.

not sure how useable it is though? I personally have found there is already too much power from 4000 to 5000rpm and it needs to be 'dampened' down to make the car driveable......... nothing worse than too much torque @ from corner apex, only need to look at a modern 2014 F1 car to see what I'm talking about!

310kpa or 44.9psi!! (only in the top of 3rd and 4th gears tho, I'll fill in the boost everywhere else next season, plus more total if needed) 162.5mph to date.

The engine still seems happy too - 2 drag seasons, 2 powercruises, 1 dirt drags, and some street use later. Hopefully it does a 3rd drag season.

Surprisingly enough the engine appears to be several times more reliable than the methanol 13B's we race against. Trap speed is equal to the methanol 28x9 tyred cars too (this with our smaller tyre and heavier car), and there is still more power in the engine yet I'm sure.

In retrospect it's quite amazing how much reliable power such a low spec basic engine build running on petrol can produce. Only with WI of course, it wouldn't even get close otherwise. Frank Walker of Pratt and Whitney resoundingly proved this all those years ago.

Still running inductive ignition too. It's cheap and reliable.
