Default A&A or ECS???

Fellas i'm looking at going forced induction. Is one kit significantly better than the other?

Depends on who you ask. They are both good kits. I've had both, and I like the ECS kit more. I like the intake, blower, brackets, restrictor plate, pullies, tensioner, BOV, Upper pipe, Customer service much more than the ECS kit. That being said you won't be disappointed with either kit.

Remember that the ECS kit comes with the Novi 1500SL which would be a T-trim v3 on the A&A kit so add that to the price. I like that I can change a belt in 10 minutes, A&A kit was a pain. The metal pullies that ECS uses are far more durable than the plastic ones in my experience.

These statements are confusing. Would you care to expound further? I am contemplating a FI kit as well.

No thoughts of the new Magnuson Heartbeat supercharger?

What about them?

I like the dongle/air filter on the ECS kit more. Seems to flow more.
Novi 1500SL with the billet case is a much better blower and better fitted for the vette than the base A&A blower. If you pay extra you can get a similar blower. Bracket design on ECS kit is much much nicer. Adjusting tensioner, swapping belts, fit, etc are all better. Makes it easy to swap belts in <10 minutes compared to hour+ for A&A. ECS uses a restrictor plate for more low end torque. ECS uses nice steel idlers compared to the plastic ones ECS uses. My A&A kit was squeaking from an idler not long after install. They are a pain to replace. ECS idlers are really easy to get to and replace if needed but I haven't seen one go bad. ECS uses a Tial BOV. Best BOV made IMO. ECS has a nice 4" upper pipe. I think the newest A&A kits have 4" uppers or it is an added option. ECS will also set it up for meth/IAT/etc no charger and powder coat whatever color you want. Same with the brackets/etc. Just ask them. Want a hot pink kit, they can do it. Doug/Chris and Matt@FSP are on top of customer service/support.

I know two people who have swapped from one kit to another and they both agree. That being said, both are good.


Magnuson would be ok if it was 1/2 the price and made 100rwhp more. The whole idea of more low end/etc makes no sense to me unless you are planning on competing in a burn out contest. The ECS kit makes tons of low end torque and can roast the tires in 1st/2nd at will so what would more low end do? Make it so you roast them at 50% throttle instead of 80%. Back when a blower took a car from 200rwhp to 350rwhp and there was still traction I can see the appeal of a PD blower. No that they go from 400rwhp to 600+rwhp and tires are the limiting factor I don't see the appeal. My car makes 750ft/lbs at 3000 rpm with an ECS kit. Even at 1500rpm it is making 500+ftlbs.

Take it for what its worth the guys that bought the A&A will say that and the ECS guys will say that....

BUT I can vouch that more importantly the customer service at ECS is unparalleled. They REALLY go out of the way to help you when issues pop up or you have questions. For that reason alone I would pick ECS (well that and I do think their kit comes with everything it should from the start... no reason to "upgrade" anything straight off the bat.

Exactly, anyone who bought an A&A kit is going to rave about how great it is, anyone who bought an e-force will, anyone who bought an ECS kit will love it.

As one of the few that has had both, on the same car, installed both I like the ECS kit more.

Comparing your car to a street boost level (8 to 10psi) p/d blown vette is a little disingenuous....at best. Turn off your meth and turn your boost level down to street type boost levels and then note the tq or hp at 3000rpm. You'll be making little or no boost and have little or no hp increase over stock. Not everyone wants to run meth and/or risk a blown motor. When the VAST majority of your engine speeds on the street are below 5000 rpm, it makes little sense to me to get giddy over your power at 7000rpm. I'd much rather have the extra power available any time I choose to use it.

Absophuqueinlutely, grab you a centri if hard core racing cranks your tractor. Not everyone is in to that though. Lots of folks want a solid hp increase at ANY rpm. For a mild street ride, on mild boost, the p/d blower is the way to go.

Car runs fine off meth, just makes ~950rwhp instead of 1050rwhp.

Using big words does not make up for the fact that your low boost/ lack of any additional power reference is incredibly incorrect.



OP, feel free to give us a call if you would like to discuss the ECS kit with us.

Was that at 8 or 10psi? Like I said, back it down to livable street type boost levels and compare.

Overlaying a centri blower car with a n/a car the centri still makes a ton more power down low, not "little to no increase". That is simply wrong.

My car made 400ft/lbs at 2k rpm with the SI-trim 5.8psi peak boost. Stock it didn't make 400ftlbs until 4400rpm, and by 2500 RPM the centri was making more torque than the stock ls7 at peak. That was without the ECS restrictor which bumps low end up even more.

How much boost was it making at 2K rpm? Every centri I've ever seen running at mild boost makes no boost at 2K rpm. If it makes no boost there, to what do you attribute the power increase? I understand why your rig makes the power down low. Isn't it running at well over 15psi.

Blower is moving a set amount of air down there, maybe not enough to build boost but it is still moving more air than an n/a setup. That was the old 5.8psi stock motor setup. New setup is 18-20psi and makes tons of power everywhere, but so did stock motor low boost setup. In fact I would say it was snappier and made more torque because the 11:1 compression compared to 9.7:1 with current setup.

How could it move more air than n/a and there be no boost? 18 to 20 psi kinda gets you into full blown animal territory I agree on the 11:1 motor being snappier. Same happens when comparing a higher DCR cam vs a lower one on the same rig.

Hook up a vacume guage to your NA engine. Intake is still under vacume at WOT. With a centri at 0 boost/vacume the engine's getting more air.

Anyone else care to share objective comparisons and differences between the ECS and A&A kits?
