I wonder Dyno INJEN vs Perrin CAI.
What grade of gas were you putting in before?

I do not know, I put the intake the day i got the car, i think the dealer might have cheaped out on me and put 87 ...
BUt now it seems to be a lot better. I haven't had a chance to drive it around yet because of the snow and i'm on summer tires.

Anyone ever wonder why HKS, one of the pioneers of the mod business, would go with a non CAI for this car? Makes you wonder no?

Also makes me wonder if you couldn't just slap a cone filter right at the throttle body to see what that would do. Sort of like what HKS did with their set up.

Agency Power also has a setup like that. I don't know if anyone has had the stones to purchase/install one yet.

I'm all for actual testing but that's a real expensive piece of equipment for an academic experiment on what "not" to do.

True, but you could go out and buy a K&N cone filter that will fit the throttle body and try it out. Couldn't hurt and it probably wouldn't be all that expensive either. Anyway, I was just thinking. Since the intake side of the house for our cars has gone sort of nuts.

I suppose you could but you would still need a place to mount the MAF. I wouldn't want to drive it hard in any way without one.

Amen to that brother!:happy0180:

Maybe when the day comes that I buy the full Perrin CAI system I will hack up my Injen and try what you are talking about. MAF and all.

I don't think that I have noticed any significant difference in performance but I can tell you that I have had zero CELs or idling issues. Honestly, the HP difference between it and my old K&N drop in I had would be so minimal it would be within the error/correction limit on any dyno.

Still, it cleaned up the engine bay, looks nice, sounds fantastic and got rid of the noise generator! All plusses but you won't here me say it was worth the money for performance gains because it isn't.

No idling issues? You're lucky, I've been having idling issues ever since I've installed it and am highly considering going back to stock and a drop in.

Also could be the ECU adjusting to the intake. I had the same issue when I got my aFe.

So I broke down and bought the AVO inlet tubes along with an AVO drop-in panel filter. Which means once I get some time, which is usually never, I'm going to ditch my Airaid intake system and go back to the stock intake + the new AVO inlet tubes & drop-in filter. I'll see if there is any difference at all and if they are positive. Hate to say it, but even though the Airaid was found to loose power, it felt and sounded great to me. That added w/ my Perrin CBE proved to be a great combo. I just hope that this will be an improvement, because if this doesn't cut it I'm absolutely done at throwing additional money at the intake and will probably just go completely stock.

You guys should invest in an intake with a pinwheel of sorts best gains.

Btw, has anyone else done testing with the snorkel? On or off?

I know someone posted the temp differences with and without it, but just wondering if there was anyone else who tried some tests and found some additional info/data. I've been avoiding taking the front bumper off and would rather not have to if not necessary. I'm pretty sure that the bumper will need to come off to re-install the snorkel back onto the car.

I do remember some guys posting that deleting the snorkel proved additional air flow? Am I wrong to think that the deleting the snorkel would actually allow more air flow into the air box? Even though the air temps might rise w/o the snorkel, could the additional air flow out weigh the added temperatures? Just a thought. Again, I'm trying to avoid taking the bumper off to re-install the snorkel unless I really really have to.

I dynoed it, as well as did air temp testing.

2-3whp difference, consistent.

I was actually thinking of getting a pair of stockings and just blocking off the throttle body like we did in the 80's.
