[Dave at Pelican Parts]

The people in one of the local classes (P-production, for you PCA zone 7 folks) like to say that they are getting 130 HP out of their four-bangers with the stock FI. I don't know if they are really getting that much out of it, but it doesn't sound like its out of the question.

Bp-allowed mods include a 0.5 boost in compression ratio. That means Euro P&Cs and then a little teeny bit more. They can use any ignition system that goes through the stock distributor. They can use any exhaust. They can also use the full range of adjustment for anything on the car--like the ignition.

The Pete Weber headers or Kerry Hunter headers, plus a high-flow muffler or a set of Supertrapps, are a good way to go with the exhaust. The K&N filter *might* give you a bit--ditching the stock air cleaner and mounting a cone filter over the throttle body might help a bit more at the top end. (Have to do something about all the vacc hoses though.) The compression certainly helps. A hi-po ignition and wider plug gaps might get you a smidgen. A little here and a little there can work you up to the neighborhood you want.

Chances are reasonable that you'll have to do some tweaking to the stock FI to get the most out of the changes, though. An air:fuel meter (DIY like in the Pelican article, or buy one from CB Performance, etc.) can help, but dyno time is probably better.

A mild cam will get you some top-end at the cost of a little bottom-end. The FAT HP440 grind has quite a few fans.

A light flywheel will not get you any power, but it will help the engine "spool up" and back down again more quickly. It can also make the launch from a stop a bit more tricky, and may tend to let the engine stall more easily when you push in the clutch and let off the gas.

Hey, if you're willing to take the compression up to 9.0:1 and run super unleaded mixed with race gas, you can probably get the power pretty easily!

Of course, engine life will suffer some with any real increase in power--but it should be fun!
