Florida probably has the worst weather for performance, so when the humidity drops the difference in power isn't just there, its amazing. Power in the morning, or when the sun goes down is SIGNIFICANTLY better then mid-day. The main thing I notice is initial acceleration. For instance, during mid day, if I floor it in second around 2600rpm, it will be a little boggy. But at night/morning, the acceleration is more crisp, with more torque behind it. And our night/morning is probubly HOTTER then most everyone else's mid-days. I can't WAIT till winter time, my car will be lethal.

Now, intercoolers...suppose I added an air-to-water intercooler right now. Wouldn't that be the equivilent to my car running on the coldest december morning? Now imagine having BOTH, the freezing cold weather, AND an intercooler. Wouldnt that be like double the power? I swear, if so it would be like a 60hp/tq combo. I know the VQ hates the heat, but I am convinced the supercharger hates it more.

Thoughts?

All Hail to the V1!

 

Well, by no means would I call mornings/nights here in Central Florida cold. Still very hot and humid. But without the baking sun, its a few degrees cooler. And yes, I notice the blower is a little louder. As far as sound, my blower is the opposite of a roots. Mine is ear peircing loud under 2000rpm/idle, and quiets into a jet like whine at full throttle. A roots is silent at idle and partial acceleration. Under WOT it howls like a warewolf though.

Its good to have that exotic shreek at idle/low rpm, b/c when your cruising through the neighborhood/mall/traffic/ect. everyone within a 300ft. radius can here it....heak, my compressor is way louder then my exhaust.

 

I'll let you know how the 30 inch wide FMIC does when it hits the 40's here in atlanta

 

I am pretty much convinced to get a Air-to-Air intercooler too. Now gota find the right piece and time.

 

The SC isn't affected by heat. The problem is that the SC produces additional heat, which the engine isn't too fond of.

I really like the idea of a AWIC. Get a big enough tank and you can fill it with ice water and run colder air than the outside temperature. I think that's my plan someday. It would be perfect for the track.

 

Yep. Having an efficiency greater than 100% definitely has its attractions. Makes you feel like you're violating one of the laws of thermodynamics or something.

For every day use, though, AWIC's are less efficient than a well executed FMIC since you have two exchanges going on instead of just one.

True. Decisions, decisions.

AWIC you have to deal with the water container, pump, and heat exchanger. FMIC you have to deal with intake piping and pressure drops.

Not sure which route is "better" at this point for us SC guys.

 

How about an Aquamist system? I have an old issue of SportCompactCar with Superchargers as the main article and it talks about that system. It makes cooling look more promising for us SC'ers.

 

I heard that water injection stuff isn't really good. Besides, doesn't it need re-filling, where as a FMIC, like the SC itself, is perminent?

Who else agrees that a well done FMIC could yeild significant gains? And would these gains be only in boost?

 

From what I've researched - the Aquamisto nly needs to be filled about every 800 miles under "normal" driving.

I'm putting one in my trunk one of these days and putting the Washer Level sensor back there and running wires back to it from the harness up front where the resiviour is.

That way, when it gets low, I'll get a light on my dash.

 

the aquamist water injection is a very good system. i own 2 mr2s a 89 supercharged one and a 91 turbo and almost all mr2 guys have and swear by the water injection. its not really a question with them wether they have it or not its just kinda mandatory. stopped detonation in both of my mr2s and plan on adding it to my new found maxima as soon as i get the forced induction system in. still not sure what i am going to do yet so if anyone has any ideas of what i should do will be appreciated and please back up your reasons. thanks.

 

I just came across this while cruising through twinturbos.net:

"I am ditching aquamist as I have blown my 3rd aquamist pump (VERY light duty use).
I am working with a bud to develope our own unique "diy" kit. I'm sick and tired of the lack of reliability of aquamist."

 

Kevin (Y2KevSE) already blew one aquamist pump and it costs an arm and a leg to get a replacement.

Mardigras has a write up for DIY WI kit.....it costs him 260 for all parts, compared to 420 from aquamist.

 

How about someone posts the piping diagram if I wanna put an intercooler on the SC?

 

FYI, relative humidity goes up when the sun goes down.

 

not quite sure what has happened to their aquamist systems since i have never came across one in mr2 land that failed and i have had none quit on me in the 2 1/2 years that i have had it on my 91 turbo and i put mine thru very hard use. maybe they are not using the right kind of water as almost all water has minerals that can clog it up i think. i have only used distilled water in all of mine. of course it could also be the user not the machine.

 

a shop in cali did a small fmic on a 2000 and dynod a 50 hp improvement. the article is in hci magazine. (ill try to get the details on the issue)the shop was powertrain dynamics. i put a apexi r32 skyline intercooler on mine (higher eff. than others)-im working out fuel system bugs now! ill keep everyone informed.
