I called SLP Parts the other day. A fellow named '"Art" told me "the Free Ram Air mod is bad for the LS1". He says too much hot air will get into the motor and this is very bad....... but he then said the Cold Air Induction we have is very good for the LS1. I then told him that you still have to cut out the bottom of the air lid! He said yes and your getting cold pressurized fresh air, not hot......

Art told me to expect 10Hp for the CAI and FRA mod to go with it. How can you guys justify spending $130.00 plus $15.00 shipping-total-$145.00 for 10 HP? Smooth Bellows-$60.00 inclu. shipping for 5HP? That MAF is what $150.00 for 7HP?

How can you guys pay for this?

Finally, is the Free Ram Air mod bad or good and does it make the LSI louder?

If 10 horsepower is a bad deal to you for that kind of money, stop modding now.

These cars aren't cheap to mod....

OF COURSE they are going to tell you that anything but their OWN product is bad....welcome to the world of business.

How would the air be any hotter than normal air flowing into the engine from under the hood. Also it would be colder because it is sucked up from underneath the car because of the air dams that are on our cars. Yeah they may be annoying when you hit them on low ground clearances but they bring cold air up for the radiator and the air box.

I've never heard any problems with people doing the FRA mod. If you plan on modding the air intake I'd say go with the FTRA, K&N or Holley Filter, Aftermarket Lid, Aftermarket MAF, Smooth Bellows, and Ported TB. If you combine that with a free flowing exhaust LT Headers, Free flowing cats, Cat-back and get some computer tuning done you'll pick up some HP. It's not cheap but the SOTP difference you'll feel with these mods will make it worth it.

Of course they said that, they just want to make a buck...go with the fast toys ram air....worth the money....I got an SLP CAI, after calling SLP....they said they had done extensive testing in rainy conditions, and there should absolutely be no problems with it and driving in the rain...guess what? Water got past the filter...engine went boom....that was 2 years ago.... atleast fast toys has a block off plate

GM high tech performance said it in plain english "LS1 guys are not cheap" if you want something less expensive, go with an LT1. Our parts are more because of the technology that goes into them, and technology aint cheap either. <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />

The only time that it "gets hot" would be in traffic. But how would that differ from stock?

I think this guy was on commission. I wonder if he could explain why super suckers iat's are lower than their kit? Their metal ram air retains more heat than the composite ones.

Hot air, bad for the engine? Of course it is. But that is like saying that gas is bad for your engine because it eventually wears out your rings!! I guess we had let every auto manufacturer know that they should eliminate EGR because SLP said it was bad.

The guy you talked to embodies my complaint about SLP. Overpriced arrogant bullshit!! Take this for example But I'm sure this would be bad too, because they didn't profit. I'm glad we have a choice other than them. They don't seem to realise that their monopoly has slipped on the LS1 market. Sorry about the rant.

At this point in the game, picking up 10hp for $150 is what I would call a DAMN GOOD DEAL! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I don't EVER plan to buy any SLP stuff. In fact, most of it looks like junk and NONE of the products they sell are considered "the best" for anything. And it's not like any of their stuff is considered a value either. WAY overpriced stuff.

I guess I either like to buy the best part for my application or if I can't afford it, I get the one that is the best for the price, SLP's stuff just NEVER comes close, at least not for any of the TONS of parts I've bought.

Lots of people have done the FRA mod, and I haven't heard of any problems.

It can be as cheap as a piece of cardboard under the filter or cut up a piece of metal to fit. You can do this for all cold air induction/ram air kits.

SLP are dumb!!!common sense!!!FRA mod is a must..how could they even say its bad if whenever you install their pos cai....you still have to do that cutting anyway!!! morons.......!!!SLP!!morons....that's business for ya!!

Sited12,
What you said makes a lot of sence to me.How could the air be any hotter than normal? Before i did the FRA i had a hard time determining where the air was coming in at.

Common sence tells me there would be more cold air w/FRA then if it were stock.

I think SLP cold air and FTRA are better than FRA, and that Art is right, you will pull hot air off the radiator but there can be a mph from FRA. I think the gain from a FTRA is better.

With a FRA you will pick up some warmer air when standing still. This is because hot air rising off the radiator will now get into the intake. I've seen IAT's as high as ~125* idling in hot weather with the FRA. However once you start moving the IAT's drop fast. The FTRA or SLP CAI blocks a portion of the radiator directly below the air inlet (blocking the radiator not being something I am overly comfortable with). In theory this should prevent some of the hot air from rising into the air inlet. I'd be interested to see how the IAT's differ between the two. I doubt there's much of a difference.

Fulton, so this is a bad thing? Is the FRA still a worthwile mod to do? Over time would the idle heat damage the LS1? I'm talking long term here. It appears the pros out weigh the cons on the "Free Ram Air mod".

Ray,
The FRA has been used since the beginning and this is the first I've ever heard about potential damage to the engine due to warmer air. IMO its a worthwhile mod and its cheap. If you're going to do the FRA and want to gather some conclusive data, use Atap and monitor the IAT temps with the car stopped and idling (engine at operating temp). See how high the IAT reading goes. Then do the mod and repeat test. If you notice a significant rise in temp versus stock and that makes you uncomfortable then you can always return it to stock.

Generally (on an NA car anyway) increased IAT may cause a slight decrease in power and may increase the potential for detonation. I emphasize may because this would be the worst case scenario. I haven't noticed either problem and I've been running the FRA for years now. Personally, I wouldn't worry about it.
