SRIs in texas

mrjre42 · 07-27-2008, 04:12 PM

So, im contemplating getting a SRI. I've heard, of course, that having one in hot weather results in power loss. im curious if that is noticable in the dfw area during summer. any thoughts?

And, just to make sure I dont get the "you should get a CAI, its better", I'm going to college in Illinois so I dont want to deal with the risk of sucking up something...

Where did you hear a SRI in hot enviroments results in power loss? im in a location that is 85-95 year around and am considering going with a SRI. I already have a injen CAI and im tired of worrying about sucking up water considering it rains atleast once a day.

^ Ya, it's pretty hot down in College Station... never heard of power loss... :X

so do you have an sri? and have you had any issues with it?

***ASHRAF*** · 07-27-2008, 06:48 PM

heatsoak causes loss in power, that's what I know

I have an Injen SRI, and yes it's noticeable

but I would rather loose some power, and not risk hydro-locking the motor with a CAI

mrjre42 · 07-27-2008, 07:06 PM

ok, so are you comparing the power loss to what its normally at or when your si was stock?

Good question... :X... I'm confused now... I had a SRI on my old Civic... It's definately better than stock, but ya there would be power loss compared to normally due to heat soak...

more confusion?!?

so what you're saying is that there is more power compared to stock, but there is a loss of power compared to, say, a 50 degree day?

regardless of the heat the engine bay is hotter, but the reason you should see MORE power out of it is the increased FLOW, you dont have to worry about temps or anything like that untill youre dealing with boost

TexasK20Z · 07-27-2008, 11:14 PM

Both short and cold air intakes suffer from heatsoak since HEATSOAK describes the metal pipe heating up. The SRI heats through normal engine heat and the CAI heats both by engine heat and that it sits closer to the radiator. Heat soak has more to do with the use of METAL (and aluminum at that) than the short or cold.

Since alternatives are short (none... well there is one, but it requires the relocation of your battery) for intakes made from NON-metal substances, you will do good by either choice you make.

If it were my money, I would wait for the PRM intake... but if you were looking to buy right now, look at the new model of the K&N... and then funnel cooler air from your front air damn to it through the OEM plumbing...

It's definitely better than stock, the comparison is between normal weather, and hot weather

on hot weather you have a significant power loss that you can feel, but i would still recommend the SRI

I can't really compare just the intake with stock, because this is not the only thing I have

Demonis · 07-28-2008, 11:59 AM

I had the original K&N and loved it, not a largely noticeable gain (then again, what bolt ons do?) but the sound was fantastic.

Lan Evo VIII · 07-28-2008, 12:43 PM

Go with a CAI and call it a day. If you see rain that is bad enough to where it would cover you intake stop. Even if you are not sure how deep it is Stop.

That's not always possible, I plowed through at least a foot deep of water on the highway once (around a corner, no one even had a chance to brake before plow!), and even if I could stop, its not like there would have been a way out of it.

If he's going to Illinois, he shouldn't get a CAI for a daily driver, it will be a pain. Especially on a new car.

VTEC_4_LIFE · 07-28-2008, 01:15 PM

yeah SRI is definately much safer way to go, and its also alot easier to work on when it comes time to wash the filter or what have you

and yeah no to CAIs in TX< because down here when it rains, IT RAINS

IndyMike · 07-28-2008, 01:32 PM

I agree I had a budy hydrolock his Civic 4 years ago in Indianapolis when I was living there. He driving into work and splashed a puddle which was much deeper in a lot than it looked....probrably about 4-5 inches in the deepest part and there went his engine.

I used to have a CAI 6 years ago and had the AEM bypass valve on it for peace of mind but installing it meant cutting/modifying the tube which undoubtedly had an effect on the performance a bit.

With the 100+ degree weather you can feel some heatsoak especially in stop and go traffic but not horrible to me. I was getting as much if not more bogging from time to time on the stock box. I will say at night when it cools off a bit I can definitely feel a very nice improvement in power and throttle response. What I also like about the Injen SRI is it sounds stock till you really get on it and open the TB up then it sounds very nice.

The few extra ponies agained on a CAI vs SRI just don't justify the risk....even if many will argue it's minor.

my car is my daily, so i didnt want the hassle of always worrying about sucking up water or something...

so what im hearing is that although there is some noticable power loss due to heat, its not that bad? and thats only with stop and go traffic?

right once the car gets moving cooler air is taken into the engine bay and thus sucked into the intake

Agreed... SRI is the safest route...

trystar · 07-28-2008, 09:26 PM

i live in houston and i have a fujita sri, with a CAI you won't notice power loss when taking off from a stop but with a SRI you get heatsoak b/c you're idling and there isn't airflow in the engine bay. once you're moving though, the air that's being forced into your engine will not affect your power because your SRI is being fed cooler air and you'll actually be gaining hp.
