Currently, i have a stock port 12a(42,000km), RB road race header, 2.25" exhaust, nikki with a vacuum diaphragm mod, rats nest delete, and no accessories other than the alt. What would I be looking at roughly hp wise?

Now im looking at getting a dellorto DHLA 48mm setup with rb intakes. What kind of improvements would I see with that?

My setup dynoed to 134 whp with the setup in my signature except for 2 changes.
The ignition was the 2GDFIS and the exhaust was the old RE performance exhaust
system. I now have a stronger ignition and the RB SP exhaust instead. I expect a bit
more next time I get a chance at the dyno.

With your unmodified Nikki you will fall off at the top end and lean out. Not sure how
your exhaust will effect thngs but at least its less restrictive than stock. You might
see 100 or so as is. Adding the Dell will probably get you around 110.

been a long time, but back in the day when Pro7 was hot we'd see the following, and since these racers were actually serious, the engines were usually fresh built, new rotor housings, flat irons, all new seals etc etc. AFR's were tuned to be optimal, stock ignitions. synthetic oils in the drivetrain.

Pro7, which is 81-85 nikki and manifold, stock port 12A, stock exhaust manifold into a 2.5" exhaust pipe, 112-116rwhp.

ITA, which is Pro7 with a header, 120-125rwhp.
