Company is sellouts isnt that what you do if your a company? Not that i like slp they do overcharge for most every thing.
Back on topic my buddy had an asp threw a belt in a week changed over to slp never happened again but some people say asp has fixed that problem now.

When SLP starts giving away tee-shirts and hats and emblems and having FREE track day for customer appreciation and then the following year makes you pay to get in and then the next year doesnt give away **** and makes you buy the PREVIOUS years teeshirt and charges you an arm and a leg for it and then the year after just cuts the day COMPLETELY OUT after scheduling a date for it.

Yeah I call them sellouts and bad customer relations.

SLP Headers are HORRIBLE. Their products are OVERPRICED and usually less then the competition in superior category.

I wont deal with SLP anymore just before of SLP day going to hell.

ASP here. But there is really no reason to choose one over the other. Just go with the one you like the most.

Thats a lot more effort than the GM guys did in supporting the EFI nationals.

I have the newer ASP pullies and haven't thrown a belt once. I heard a few years back and seen some dyno's that the SLP pullies have a dip in the power at 5700 RPM for some reason. I am pretty sure they fixed the problem since then but it was still enough to keep me away the SLP Pulley. I havent searched yet or had to worry about it but the only thing that makes me wonder about the ASP is how to take it off I ever need to since the middle is all filled in.

ASP pulley here, no belt issues at all. It seems like the March pulleys are the ones throwing belts lately. Seen a few threads of people who had to buy new tensioners using March pullies.

Do pullies affect future supercharging plans?

ASP pulley, no problem other then the engine revs faster, and I get better gas mileage. ASP with new belts is the way to go IMHO. Good luck, and no power dip at 5700 rpms with my pulley.
