hahn big sidemount worth it?

[MyBeatGSX]

For 300-350awhp is that big sidemount enough? I don't want to hear people blindly saying "just get a front mount", I want real informed answers. Is it good enough for that power range? I'm just looking for something with better flow and the ability to make a 3rd gear pull without heak soaking it after the first 3 seconds. Its also 100000% easier to install than a front mount and much cheaper. I also won't have radiator blockage issues, and going with the rest of my car its sleeper. But will it suffice?

What turbo set up do u have,,is turbo stock,,they say a super sidemount is rated around 400hp,if u have no budget get a hahn super sidemount,a cheap route is a supra sidemount,it can handle 400hp easy...

 

[staticbrainwash]

I've been debating this same thing for a long time. And never really found a real answer in all of my research. I was hoping not to have to purchase new u&l icp's, and just retain the ones i've already bought.

I read good things about the hahn better things about the supra, but never any solid info about heatsoaking. All in all, i myself am leaning toward a small frontmount. Not that much work to get them on, and nothing needs to move. Not to mention less chance to overheat with a small "street" style IC over a big SBR style "race" FMIC.

Why not just go water injection and not change anything? This is even cheaper than a bigger side mount, and you'll get better results.

I an running over 300 whp with the stock sidemount and water injection.

 

[staticbrainwash]

Water/alky injection is a fantastic option, but you also have to worry about your tune on the motor when and if the water happens to run out. Is your car a DD? Because i couldn't see (and maybe i'm just damn lazy) checking the water everyday to make sure it won't run out.

I don't know about the OP, but I would like something a little more self sustaining (i.e. fmic or big smic). Do you have pics of your water injection set-up? And how big of a water tank do you have feeding it?

 

[tom04841]

i don't have pics, but i tapped into the stock windshield washer fluid tank ans also put a fluid level sender in it and wired it to a LED inside the car so i know when the fluid is low.

I built my whole set up for about 150.

 

[staticbrainwash]

Ah, a led sender for a low water level. Thats a damn good idea. One i never thought of, and actually makes me rethink running water/alch (washer fluid). Even if i could get away with alky and a minor sidemount upgrade. . . Hmmmmm. Looks like it's time to do some serious water/alky research.

 

[4BangR-x]

I used to be into old saab turbos, and water/alky is one of the best options for them. Its cheap and effective, one of the best mods out there.

 

[staticbrainwash]

My question now is though, how much HP can a stock sidemount hold up to with water AND alky injection?

And even back to the OP, Is Hahn sidemount worth it When options like alky/water injection heed MUCH more helpful results? Probably not, But coupled together is sounds like the could heed a VERY agressive combination.

 

[keymaster]

I'm running the Hahn on a small 16g. On 20 psi creeping to like 23, I could heatsoak it on 4 back-to-back runs in the winter, but that's also high boost for that turbo. Anything much over stock boost levels and the stock SMIC becomes quite a large restriction. Even with water injection, I'd at least get a big SMIC to free up some of that restriction.

 

[staticbrainwash]

I do agree about the flow restriction, but what about water/alky injection in the form of a good washer fluid?

I still think a good sized SMIC with alky/water would do quite nicely. But it's all in theory.

Does anyone have ACTUAL experience with SMIC's and water or water/alky?

 

[MyBeatGSX]

I refuse to run water/alk injection, its retarded and nothing but a bandaid at these power levels. Please don't debate this, just get back on topic. I need to make a decision about this so I can get something installed and tuned before going to the track on July 7th.


So back on topic. We have one person running a Hahn and it heat soaks after 4 back to back pulls in below freezing temps. Not bad, seeing as how my stock sidemount heat soaks after 1-2 hard pulls even on a cold day. But as I already said, I only need it to last through 1 drag run at a time without heating up too much or being a flow restriction. I'm not looking for constant cooling, I don't auto-x often and never run road courses. Any sidemount will heat soak faster than a front mount simply because it doesn't have much mass to absorb the heat.

The question is, just how much flow does a big sidemount free up? Is it still a significant restriction? I don't want to spend money on something that I'm going to find out isn't adequate.

 

[staticbrainwash]

You're going to piss a lot of people off with that water injection comment.

Just go with the sidemount, you seem set on it anyway. If you look on dejon's site at their "super sidemount" And compare it to stock. In fact, i believe it even has a flow increase percentage over the stock sidemount.

And for future refrence, you don't need to be an asshole about a simple suggestion. We're all just trying to help, so keep the comments to yourself.

 

[keymaster]

MyBeatGSX, you act like you're running some massive amount of power. You have an Evo3 turbo with basic supporting mods. There are guys running twice the amount of whp you are, that use W/I on a daily basis. It's not a bandaid in any way shape or form, it's simply another method of knock suppression. You obviously need to do more research before you go spouting off at the mouth.

To answer your question, the Big SMIC frees up a ton of flow over the stocker. You could drag all day with it, as long as you allow a few minutes for cooldown.

^^ Thank you.

"These power levels" ooohhhh wow 260whp....I dont know what I would do with ALL that power on a sidemount!



Get a Frontmount, it's on your wishlist....you know you want one, dont be lazy. It will be worth it

 

[MyBeatGSX]

"These power levels" ooohhhh wow 260whp....I dont know what I would do with ALL that power on a sidemount!

Exactly my point. Water injection is a joke at this power level, get a correctly sized intercooler, correctly sized turbo, and tune it right and you won't knock. Simple as that. If you need water injection to make <300hp reliably on these cars then you're doing something wrong.

Let me know when you're running 500+++whp and then water injection is a legitimate tuning strategy.

To answer your question, the Big SMIC frees up a ton of flow over the stocker. You could drag all day with it, as long as you allow a few minutes for cooldown.

That's all I needed to know. Thank you.

I ran the HRC SMIC on my evoIII for about 4 months till I saved up for the FMIC that I wanted. Short answer, will it work? yes, does it work that well?, no. At 18 psi on my evoIII I would often see knock by third or fourth & this was on the first pull. The car was also tuned on the richer side @ 10.5-11 to 1 on Ultra 94. Switched to a Victory Performance short route fmic & knock is gone. Running 11 to 1, don't see knock through 5th & have added a few degrees of timing from 6500 rpms up. I also gained 2 lb/min in airflow just by switching between the two setups (still running the exact same amount of boost). Currently running 20 psi daily on the fmic with zero knock issues, defently worth it IMO.

People that say it works great, switch to a FMIC setup and then tell me it still works great

 

[gr8popp]

I think the lagrger side mount is good if you want to have a good sleeper. The hahn smic is more efficient than the stock, but it doesn't scream HEY I HAVE A TURBO so you can catch more people off guard. If you don't care get a fmic.

I couldn't agree more. I ran a stock SMIC and my charge temps were 200F+ after a full 1/4 mile pull. I switched to a Dejon super SMIC and the charge temps dropped to 160F after a full pull. I went from seeing tons of knock through 3rd and 4th to minimal knock in 3rd and like 11-14 counts by 4th. The AFRs were around 11:1 in both cases. Yes, it "works", yes, it's alot better than a stock IC, but it's still not the ideal solution. If you're going for a sleeper look, great. If not, consider other options. I personally am going for a stock appearing setup, so I've recently ditched the big SMIC and I'm doing a water/air setup in the stock location. Think FMIC efficiency on the street, sub-ambient charge temps at the track, and low pressure drop through the core.

 

[mitsuclipsegsx]

Isnt the hahn like 500?

 

[MyBeatGSX]

Is it really that much? They don't have prices posted on their site and I haven't had a chance to call them, I assumed it was <$450. In that case its definately not worth it.

Its good to hear from some people with experience.

Steve, how much is that water/air going to run you? I've seen them on a few DSM's and liked the very simple charge pipe routing. I'm assuming you need to buy an electric pump, lots of lines, a large heat exchanger... must be expensive, but could be worth it. Does someone make a kit or are you building it yourself? My friend has an Ion Redline that comes stock with a water/air intercooler, I've always been very impressed with those things, we've made 5+ back-to-back dyno pulls and couldn't heat soak it, the thing gained like 3hp per pullWTF .

 

[RamenPride]

I got mine used for like $260. Unfortunately, I can't offer much help as I don't race and every time I decide to do some logging the batteries in my Palm are dead.

 

[daren_p]

HRC does have prices listed, you just have to follow the prices link and everything is listed there. The SMIC is on sale for $350 but yes it was $450 or so, defently not worth the price IMO. I just picked mine up used so it wasn't so bad until I could get the VP setup. I think even for that price I would look for a cheep fmic setup if you have a limited amount of funds. There is a huge thread on here on Ebay fmic setups, they seems to be getting very good reviews and are about the same price as the HRC sidemount.

For water/air, you'll need a tank, pump, lines, core/tanks, and heat exchanger. You can piece it together for no more than a good FMIC if you're thrifty. I'm using the following:

5 Gal. alum. fuel cell $120 ebay
Jabsco water pump $100 ebay
rubber hose $40 pep boys
core 8x6x6 $250 (PM me if interested)
end tanks fabbed by JMfab (price to be determined - free if you can weld)
heat exchanger $30 Honda motorcycle radiator ebay

We did tort's whole setup for around $800, and he gained 3+mph over his FMIC. Then he sold his FMIC for $600
