I've done the CAI system on other cars... that's what I would do if it were my $$$. I've noticed improved throttle response with some CAI units.

They are two variations of the same thing. Some people claim big gains with the Vortex, others (and 1 of them friend of mine with a highly modified L98) actually lose power.

I heard that if your car is basically stock,,, they are bad Azz, but with MODs,,, they hold it back quite a bit,,, I dont understand that but,,, thats what I have been told...
Aguy at TPIS of San Antonio told me with some L-98's they have seen 25 extra HP on stock vette........
I think I am going to pick one up,,, besides they look cool as hell huh,,, dont you think......... :cheers: :cheers:

Do yourself a favor and do not get the clear box. Many have yellowed over time and look like hell. There was a HUGE blowout here probably about 2 years ago. I think it was something about the ducts cracking or not fitting or warping. I can't remember exactly what. Supposedly the units were redesigned to fix it.

I think the reason some people are not seeing gains is due to going too lean.
With a ram air setup you should run a little rich at low speeds so that it doesn't lean out too much as you pick up speed.

I wouldnt expect any big gain, and even then marginal over a K&N open lid.
They look good, sound good, but dont do much for performance.

But to think that it is not better than an open lid, I find that a little hard to believe.
I realize the mag exagerates a little bit,,, but when they say you will gain 20 and then I only get 3 or 4?
I mean I am not flaming,,, but why hasnt anyone said anything about false advertising?
TPIS,, which is a pretty respected company on the forum and with all vette owners and f-body guys,,,, Thye say the air foil get 10hp..... Why would they say that. Yeah I know so you buy the POS right?

Re: What is a better set up?? (1990CORVETTE)
Its not false advertising if they never tell you how the test went about, they dont give details. We've complained to Ecklers about it before, and nothing ever gets done.
If an airfoil gets 10hp, then they did something else to that engine to get it, because the airfoil didnt do sh**.
Yes, anything you see in Ecklers, MAD, etc. that says it gives a big HP gain is basically a lie if applied to a motor that runs great and is in tune now.
Only thing in the catalogs worth buying is exhaust, that does give gains.
People here have tested the various intakes, and they really dont give the help they advertise. Those like the SLP or TPiS would be good on a modded motor, and do help performance-wise but not nearly as much as they tell you. Not on the stock L98 at the least, the only way id expect a 20hp gain is from having either a bigger engine or a radical combination and have a dirty filter and the stock lid.
You must also notice that the ones that require a hole to be cut in the shroud alter the airflow over the radiator, so you must have some cooling mods to run them because it will overheat much faster.

Re: What is a better set up?? (vader86)
My favorite is MAD's advertisment for flowmaster exhaust. Claiming 70 RWHP gain on a ZR-1. :lol: I hope they don't expect anyone to buy that! An exhaust is worth about 20 hp max.
