So right now I have I/H/E and I am looking for more power. I don't want to add a pulley due to all the nightmares but, what else can I do without going F/I?

 

get a piggy back and tune ur car....might not do much but only get u a couple tq/hp

 

What nightmares are you referring to? I don't personally have any pulleys but a lot of people on SL do and I've honestly never heard of any problems. A pulley would be some moderate power (not much) but if you install it properly you shouldn't have any issues.

 

I have just heard a lot of people have run into problems. A lot have not as well, but I am not really willing to take the chance. Plus the pulley will not create power which is what I am looking for.

 

Thats true it doesn't actually create power but it'll definitely free up more power than you had before.

 

X2. But your gains will actually be decent, usually 10whp or more on a manual with I/H/E bolt-ons. Only downside is dyno time, which can be as much as $125/hour for a good tuner.

Check out what this guy has done primarily with I/H/E + Camcon:

pulley's are a must for every N/A... there's nothing to be scard of from a pulley. i heard NST is a pretty good.
