if a 200 shot gives what, 150bhp? then thats a 100% increase in power, so approx 300bhp from the car.. i know its only 300bhp, but it'll still be quick enough to cause upset lol
Thats the key thing, you will find that any nearly any engine will run cleanly on shots of greater than 100% (if using a decent kit) but you may have to retard the timing so much that you end up with it less effecient.
100bhp jets would probably give you over 100bhp on that engine, so might be worth trying that before you start wandering down the "diminishing returns" path.
