MSP: SRI vs Injen Long Ram intakes

Pros and cons?

I'm looking to buy the cx racing front mount intercooler kit. But the problem with that kit is that it takes the hole where the injen intake would go forcing me to use a short ram intake.

Was wondering what the difference is?

Wouldn't the SRI suck in hot air which kills hp?

In a forced induction car, the intake air temperatures aren't AS important due to the fact that the air is going to be heated when compressed before going into the intercooler which will then cool the charge air.

Ah ok. Saw that your also running the cx fmic. I'm assuming you also have there SRI?

Just with the SRI first will I notice alittle bit of gain vs the stock pipings?

I'm gonna build my car slowly. Saw that the cx racing SRI was only $100. Figured if start there first.
Also I took out my MBC. Sits a 6 steadily.

I have their "universal" kit and have for about 4 years now. I routed the cold side just like their bolt-on kit. I'd wait and get the whole kit together. Just my opinion. And good move removing the MBC.
 
My only concern with their FMIC is the crazy long plumbing -> shorter = more responsive. That being said, you can't beat the price and if it fits, proper bent or welded pipes are much better than having a dozen couplers holding little chunks of aluminum together.

As far as the intake is concerned, if you start with 20 degree warmer air it will never lose that heat, only gain more. Your best bet is to avoid all unnecessary heat.

So no to the SRI?

Also

I was looking on street units page and they've got some hard pipes for sale and a upgraded SMIC. Was wondering which one to go with. Hard pipes with a bigger SMIC, or cx racing FMIC with the SRI.

It probably doesn't really matter in the real world, but the engineer in me cringes a bit at the idea of easily avoided heat being sucked right in through the air filter.

There's no way to approach your second question without plugging my business so take what follows however you want. I'm currently developing a sidemount setup with a 12" x 12" x 3" core and total piping length of about 4'. To make room for the core, the kit will come with an all aluminum radiator (which will be a nice addition since the inlet and outlets on the stock ones are getting dry and starting to crack). Everything including hoses, mounts, and couplers will be included and pricing will be cheaper than doing an ETS sidemount and pipes. I'm building the setup this way for a couple reasons:

1. Short piping makes for a more responsive setup and that's paramount in my book.
2. I have three msps at the house right now and two of them have really crappy looking endtanks on the stock radiators (one cracked when I pulled the upper hose off, and one crumbled a bit when I leaned it against the wall, there's only one good one in the bunch)
3. A lot of guys don't want to have to cut up the chassis, bumper, or both to upgrade the intercooler.
4. This is the setup I want on my car.

If your radiator is in great shape, you like the look of the front mount, and don't mind a little trimming on the bumper cover you'll probably be happy with the CX racing parts and save a bit of money to boot. If you don't want to cut or trim anything, want a proven setup, and want to stick with the stock or stock replacement radiators, you'll be happy with the ETS and hardpipes. My setup is a different animal than either of those and in my OPINION better, but ultimately unless someone dynos all three back to back it'll be impossible to know exactly what each brings to the table. Here's a very basic mockup held in place with bungee cords that gives you an idea of size and spacing.

Oh dang. When will your product be up for sale? Prices? I've read somewhere that you had a webpage, but couldn't find it. Would much rather help another MSP enthusiast rather then a large company.
 
I'm planning to get my setup (the prototype) fully operational this week. Once its been driven in anger and I can be sure that everything works, I'll be making it available. I plan to have it on the website by the end of the month priced at around $700. The site is www.popeperformance.com
 
Street unit sucks anyway, their prices are ridiculous. Much higher than other vendors for the exact same parts.

Alright cool. I'll bookmark it and wait till your prototype is ready.
 
Crossover auto.com, speed circuit, corksport (although they are dropping their protege parts) stay away from protege garage and Street unit. I had a Forge wayyyyy back when my car was stock and paid less than $100 for it.

Ok thanks man. I'll look those sites up and compare prices.
 
If you want an intake just buy an FMIC kit, install it and use a spare pipe and stick a filter on the end to make a short ram. No need to drop $2-300 on an intake IMO.

I want something that actually will improve our vehicles. From the forums n pages I've been reading everybody has said to get the Injen intakes cause it shows more pep and improves hp. I'm not sure yet on where or what to do first. Just learning as I go.
 
Yes but on a turbo you want the least restriction possible for the compressor wheel. Stick the biggest pipe/filter you have room for, as short as possible. Intake air temp doesn't really matter if your intercooler is doing its job.
Injen is simple and bolt on. Let's face it, many car people are not engineers or particularly creative heh and more than happy to spend $300 on a couple pipes and a filter.
Maybe on an na car it matters. all it does on mine is make it louder lol
 
Alright then. Guess ill go with a SRI. Where I live it rains quite a bit. I've had a long CAI before on my Integra I had way back, and when it rained, it bogged like a son of a beach. Sometimes it would joke itself to die.
 
Water bypass valve will help, but the simplest setup is usually the best. Don't read too much into the really old posts on this forum, there is so much misinformation I frequently laugh out loud as I read it.

Yeah, I'm probably gonna go with cx racings intake for the protege. But I'm gonna have to relocated the coolant reservoir.
