Help with decision
I am about to place a supercharger in layaway I had my mind set on ecs 1500 kit but have had a few shops that quote me install recommend A&A kit due to belt wrap and being a street machine. I am not asking which is better as I have researched this to death. My question is for a street car which would be more ideal. My concern is traction. I do not want to run dr all of the time. I know I have to buy good tires but am concerned that the tq of ecs will require dr to hook and I am wondering if A&A kit would actually be better for use with street tires like PS2'S or something like those because of the less tq. Would it be more functional for me and faster to have A&A kit due to ability to get it to hook. I am looking to be at around 550 to 600 hp at wheels. Car is a weekend cruiser I want to keep the ability to drive any where. Thank you for advice.

Thanks I am torn because I was picking ecs kit due to the more tq and it is 700 cheaper than A&A kit. Both shops I got estimates from were fans of A&A kit which has me debating. Is their belt wrap issues at the hp level I'm looking at or would that be none issue in the 550 to 600 hp range. I want to put money down this week on one kit or the other just looking for first hand knowledge before I go with one. I'm thinking either will work and I will have turned to safe levels I may just pick the kit the shops use as they may be more familiar with that kit as well.

The argument that too much low end tq on a street car is somehow bad is just silly. If it's too much, there's that right pedal thing that can be modulated. It isn't an on/off switch. You'll probably be glad you have it after the 1/2 shift and, for sure, be glad you have it after the 2/3 shift. I'd take the ECS kit all day long vs the base AA kit. If it's cheaper, it's a no brainer.

Agree. ECS. There’s nothing wrong with a&a’s but you never know if the shops have as much experience with one as the other and what kind of margins they get for each one. I know a local guy that pushes procharger stuff because he makes so much on it vs. the others.
You can always do a larger pulley on the ecs setup or smaller restrictor, etc.
You’ll be fine with either. I’d do the lower price one that has more headroom personally, just in case

We are having really good sale prices at the moment on ECS kits, also whoever told you the others have more belt wrap was not correct. As others have said, sometimes shops will steer you towards who they have a deeper margin with, not necessarily what is best for you.
As far as traction goes I have never had anyone ask for less mid-range TQ before, but you could order it with a larger pulley. That said though the gas pedal is a potentiometer, don't floor it in first, but you will appreciate the higher TQ numbers when you are in the higher gears and have the traction available.
Feel free to contact us with any questions you may have, thanks for your interest in our products!

Yeah they aren't bad except for the tensioner slot stripping out, that's my only complaint. They prototyped an adapter that was similar to the nut you welded on to yours but I don't think it ever went into production, which is a shame. It makes things so much easier.
I don't really understand anyone saying belt wrap is an issue w/ECS? The manual tensioner literally wraps the belt all the way around the SC pulley to the point of it almost touching itself.. it's literally like a mm between the belt touching itself so not sure how it could wrap much more than that

I have this on mine now, makes a HUGE difference.. I just crank it down with 15/16" socket or whatever it was and it doesn't matter if I'm using an extension, flexible head ratchet, it ain't stripping. Makes belt changes a lot easier for guys doing it in the driveway solo. The bolt for the pulley goes through and holds this thing on. It just slips over the end of the tensioner, very easy/simple and it works great.
Yep, that's where I got the idea.. makes it way easier
