1.9 rockers!!?!?

[Ahaas96]

I had a few questions on 1.9 rockers for my '02 GTP. Zzp claims that rockers can potentially give you about 25 hp which I find hard to believe. What is the actual hp gain from them? I also have all the needed mods to safely run a 3.4" pulley; will rockers allow me to run a 3.3"?

I have the yt roller 1.9's and I would not be able to comfortably run a 3.3 Altho im not very good at tuning yet.

the difference between a 3.4 and 3.3 is negligible anyway, who cares.

I didn't notice much of a power gain with 1.9 rockers but I was able to add 1 degree of timing

I can feel a difference in the top end with just 1.7 roller rockers, it pulls all the way to shift point, where before it would fall off.

 

[wa04compg]

Yeah I would agree its not as sluggish up top but overall don't feel the power gains are as great as zzp says and I would deff do a cam instead of rockers

Rockers aren't worth the high cost in my opinion.
