I have an Injen CAI that I'm thinking of converting to a short ram. Does anyone know how much (if any) the noise from the SRI will be compared to the CAI? Right now I don't really hear the CAI when I'm driving at steady RPMs, only when I push the RPMs higher.

Are there any other things I should be concerned about when changing to an SRI? I think I read somewhere that the battery needs to be pulled to reset one of sensors?

 

No battery pull neccessary..I have my Injen in Short Ram mode...No different noises....

 

I've heard/read that short rams are supposed to be much louder than a full cai. The cai draws air from the wheel well while the sri draws air from in the engine bay. The air being drawn in should be more audible

 

I'm gonna try mine as a short ram first but heat wrapped up until the maf sensor. if i don't like it like that i'll switch it to the CAI mode.

and i have heard the same thing about the short ram being quite a bit louder. anybody have actual results on this?

 

Heat wrap is pretty pointless when you're drawing hot air from the engine bay.

CAI > SRI

The colder the air the more dense it is, therefore more molecules of o2 per intake therefore more power can conceivably be made.

 

it keeps the piping cool. there have been a few people on here that have tried it and haven't regretted it. didn't have any dyno proven gains though.

are you guys saying that you think the heatwrap would have a better effect when the intake is a CAI not a short ram?

 

i can see on a dyno having extreme heatsoak and having alot of hot air getting sucked in when it's a short ram but when your actually moving the air is moving around so it can't be that hot.

 

Yes, I think it would be slightly more effective on a CAI but still won't be that much of an effect.


True, but I bet it's still warmer than the air from down by the wheel well. Hot air goes up, cold air goes down. The main advantage of a SRI is that it doesn't have the slight risk of hydrolocking your engine that a CAI does.

 

i started my injen in SRI and it is MUCH louder than CAI mode. but i think the CAI pulls a little harder because the A/F ratio is better..not sure?

my car seems to be eating gas a lot more ever since i installed the intake.. =( and i'm driving normal now

 

I've actually noticed better gas mileage with the CAI installed.

So there isn't any definitive word as to whether the SRI is louder than the CAI? I'd like to think that the noise from the engine bay will drown out any noises coming from the SRI...

 

I was worried about hydrolocking since the first day I installed the CAI. Last week, I ran through a HUGE puddle! It must've been a foot deep. Water flew everywhere, it even cleaned my windshield a little. I was soooo scared that it would suck up some water but I immediately let off the gas...finished going through and YAY! No locking here.

 

I've had my K&N on for more than two years without any problems. I do try to avoid large puddles if possible. Hydrolocking is a small, small, small, but real risk.

 

The noise takes a slightly different tone when its SRI rather than CAI. It isn't much louder if at all. It is just a different tone.
