I hope you guys/gals like my 1992 Prelude Si Cardomain webpage. Not only does it contain pictures of my 'Lude, but you well also see some of my dyno graphs and modifications. Hopefully, those that own H23A1 powered Preludes, will find this webpage informative.

Lets start by showing how my 'Lude looks like.

This picture shows my friend's 1992 Integra GSR and the 'Lude before I installed the WW RS front lip.

My Dyno Plots and modifications list:

The first dyno graph shows my baseline whp & wtq. I like the wtq, but it lacks top-end whp. Regardless, in my opinion, the engine made good power and torque for being semi-stock.

max horsepower=146
max torque....=149

Engine: H23A1

MODIFICATION:

*no powersteering belt
*short ram intake- tenzo R filter
*by-passed cold start valve
*ngk plugs
*15 degrees timing
*removed vacuum line to intake manifold flappers

These next dyno graphs show what whp and wtq the engine made w/ a 60 shot of n2o(NOS dry manifold kit). I wish i had a A/F ratio graph to determend why the hp curve is so choppy. Do you guys notice that the engine is still making more wtq than whp? Man, this heavy 'Lude sure needs torque!

max horsepower= 183
max torque....= 192

MODIFICATION:

*same as above except for the 60 shot of nitrous

These next dyno graphs shows how much whp and wtq my 'Lude makes with the Crower stage 1 cams. Well, it is obvious that I need to tune the 'Lude by just looking at the AF graph. I am confident that I can reach 175whp with a cat-back exhaust and a good tune.

max horsepower= 162
max torque....= 158

This is the dyno w/ a .037" jet@750psi and previous mods.

max horsepower= 217
max torque....= 224
