Is the Vortech T-Trim close to a D1 aside from flow numbers or does the D1 just blow it out of the water. Sorry if this is off from the OP original question.

I have the P1SC and it doesn't whine at all! The only thing that I hear is at idle I have a slight noise of gear backlash. When I ordered mine I asked for a quiet one. The can send one with tighter tolerances.

A&A best bang for the buck$$ if you really want a after the sale service its A&A and if you can get the big *** YSI its bad ***!!the t trim is just as good as the D1 I had a D1 but it had belt issues because its gearing made it hard to spin so i would go with the biggest A&A kit you can afford they all make great power!!

Go with your first instinct.

Go with ECS....better, proven products..... just look at track performances.....most of the fastest cars are ECS. When I switched from the A&A bracket to the ECS, my belt slip problems disappeared....and I gained almost 20rwhp.

Very happy with my ECS kit! The service provided by Chris when I needed something was first class

Chris and ECS rock. They will do you right.

a/c man

you will pay way more$$ for ecs than the A&A kits!

Paying more for better pullies, brackets, no removing of the head unit to change the belt.

How many upgrades have you purchased to get your kit to where it is today? Add it up.

And when you going to beat the stock LS1/ECS kit record of 9.8 with that upgraded A&A kit?

if someone looks at the price tag alone then they are short changing themselves in the long run.

Andy @ A&A designed a new bracket that does not require removal of the head unit. It also includes an HD tensioner. Already being shipped!
In parts of the bracket, it is now twice as thick as ECS bracket. Made of CNC'd T6061 aluminum.

I put one on Corvette8189's car a while back. Here's a picture .




The CNC'd, anodized aluminum housing, Turbosmart bypass valve is far more expensive, rugged, and superior to the plastic Bosch unit.

The Ram Air intercooler system is top notch and AFAIK, Corky Bell's company was involved in the design. There is no better engineering group in the industry than Corky's. They have been doing high horsepower, racing turbo applications since the mid 70's.
That intercooler provides a great amount of space between the intercooler and condenser/radiator assembly, which allows for better cooling.

The pulleys are double bearing, and higher than OE quality. If you like the metal ones, you can get with Arun@CCP.

I appreciate my ECS bracket/pulley design alot more after helping a buddy R&R his Procharger head unit on his A&A C5 kit with updated Procharger bracket (not sure what version it was, one of the latter ones). It would have been very difficult to do by himself and the head unit definitely would have to be removed to put a new belt on. We were R&R'ing it because the idler grendaded.

Now I grenaded a tensioner pulley on my ECS kit at Texas World Speedway a few years back. I believe it was the manual tensioner pulley. I was able to get a different belt in down, replace it in the pits myself with the tools I had brought to the track and drive it home. Called ECS and had a new, beefier pulley in a few days and have been trouble free for quite some time now.

Both kits have there strong points. I do like Andy's latest intercooler design.

I put in alot of effort and research before I chose a SC. I did
not ask the members who they thought I should buy from. It's
simple the bias of each SC camp will actually prove nothing. You
will need to talk to each party that you are considering. I have
my own choice but I am not going to try and sway you. You
need to ask the tuff questions. Who has the research, who has
the customer service, who is going to answer the phone on the
weekend, after the sale. Price is one element but there are more
important things to consider. A good price on a crappy SC is
throwing money away. And don't be influenced by record holders,
you know that the SC company is not going to be in your
garage helping you. This record thing is used alot in the performance
industry, it's good advertiseing and sometimes there is RD that
will help the little guy, more times NOT though.
I am sure you will find a company that will serve your needs.
Good luck.
