Hi guys any suggestions on improving my intake heres the picture.. anyway will do, ducting, blocking heat etc thanks

My method is kinda a lot of work and money. But it would yield the best possible results. Get an authentic Scoot hood and run ducting right into the front air scoop in the hood. Super cold intake temps while the car is not moving as well as sub zero temps while at speed.

I'm currently trying to get this done, I just need someone to buy my current hood.

ditching the stock intercooler will give you better air intake temps.

Yup. Given the massive inefficiency of the stock intercooler, I would start there first.

Smitter

u definetly need a bigger IC. Then try drawing air from in front of the rad with some ducting of some sort. Hot engine bay air is such a downside on the fd. intakes normally sit right on top or behind the rad.

heres how i keep my AIT down
intake pipe is run underneath my flush mount headlight and down to the oiler cooler opening in my front bumper, filter gets direct air. combined with a pettit coolcharge III IC. Works Amazing

Smitter, that's an awesome set up!
how much did that set you back?!..

^do the stock headlights fit with that pipe in there?

Smitter

the intake piping couplers and filter were rather in-expensive. everything else needed to complete the set-up gets a little pricey. ie Single turbo kit, IC, headlights & Bumper.

Smitter

NO unfortunately it doesnt.

The stock airbox and plastic ducting, while mournfully inefficient, DOES draw air from the FRONT of the car. 99% of aftermarket intakes (including my own Fighter's Garage) do not work in the same way. However, the Fighter's Garage stuff comes with an aluminum baffle to at least keep hot radiator air off of the intake elements.

In the OP's case, I'd bet you'd see improvements in flow just by getting hardpipes. With a little ingenuity, you can build a box that may not necessarily draw on outside air, but will at least limit the amount of air you draw from the engine bay.

With that intake I think your options are going to be limited. A better SMIC would be the most cost effiective at managing IAT. Some ducting just below the intake, along the side of the radiator might also help.

Smitter's car, while no doubt effective, isn't practical IMO for anyone with stock twins or stock headlights. Despite the screened opening, in my part of the world (even assuming you don't get caught in a rain storm), that intake filter would need to be cleaned or changed every month sitting where it's at. And I doubt it would work with the stock (93 to 95) bumpers that most of us run.

ill be playing with so fibre glass soon enough myaking up some ducting so ill stick up some pics for ya just got to find a way of balancing work girl friend and my car may have to give up sleep lol

Actually, the stock airbox works very well. Especially if you modify it to draw more air from along side the radiator (search for the adam_c mod). It will very likely flow as much as an open intake but will be more heat soak less (see the intake temp comparisons on fd3s or robinette's site - link in the FAQ). The fighter's garage and pettit style intakes work also but you should consider some heat shielding (search on very old but informative posts from damian on making one).

How about this:

I just don't know if it fits with '93 spec or if you have to have '99 spec front bumper and assecories, ie. mounting hardware etc. And.. I don't where exactly this mounts?

Anyone have more details about this?

I didn't know they made Blitz Sonic Power's for our cars. I haven't checked in years though...

anyways, your best bet is to do what the others stated above. Hard pipes and a custom heat shield.

That was the BEST answer here. Your biggest win with that intake are the factory/or other rubber pipes. Your biggest loss is no scoop up next to the radiator.

1. Wrap that metal(?) shield with some heat barrier cloth
2. Cut a piece of aluminum and make another baffle that fits tight to your hood and place it as close to the engine as possible
3. Use some sheet metal to make a scoop from the mouth, to the left of the radiator and up to the cone/shield.
4. Don't listen to clowns with scoot hood 'ideas'.

I agree completely w/ the above post, try to minimize the heat transfer between the intake air duct and the surrounding hot engine bay.

In addition to that, and I think it was mentioned earlier, replace your rubber accordian style hose with hard pipes. The current hose you have now is likely to flex, and when it flexes, energy is wasted and leads to inefficiencies by making the compressor work harder.

gracer7-rx7

^You are right about that also. The intake tubing doesn't so much flex as it compresses under the vacuum created by high boost levels. The reason the metal intake hard pipes were made was to fix that issue of the stock, flexible, accordion style, plastic intake hoses compressing under high boost levels. Kinda like placing your finger over the other end of a straw and sucking until the straw compresses.

So does anyone have more info, setup & installation about the Mazda Air Guide in the link above? Is it only for the 99 spec bumper or can it be used with the stock oem version?

I ordered the guy next to my house, he owns a custom body kit shop.. I told him to custom made a carbon kevlar heat shield to block the rad heat from the bottom and the side.. I heard carbon prevents heat well.. now I'm trying to find ways to bring fresh air to my AIT how should I do it??

Crybabii

Hi guys i know its been a while but, I instaleed a greddy smic already but the air temp reading from my PFC commander states that the temps ar 60 degrees celsius.. what should I do, and thats while the car is moving when its not temps go up to 85-90 C

FearNoPiston

iTrader: (17)

jeez even with just the top cover that comes with the greddy my intake temps after sitting and heat soaking are 60c.

Make a duct that will help it cool down faster and be more efficient. what are your water temps? when my fans come on it will affect my intake temps.

Crybabii

my water temps are 89 c, sometimes it goes up to 93-95 on hot days.. but if the car is moving it s at 89c.. I set the fan to work when temps reach 89c. also i installed a duct to bring in cold air from the front spoiler.. it helps when my car is running.. my intake temps are at around 50-55c when running.. is that okay?? also will using heat shield paper thingy to block radiator heat from IC help??

I talked to Pettit a little while back about this, and they said I could order parts from their intake system. The parts are there v duct and the cover plate, both would be in total like $80, and it just allows more air to the intercooler and directs some to the intake, which seems like it would help in your case.

But along with this I want to try and figure out a way to just add another duct going straight to the intake for even more cool air, kind of like what Smitter did only the filter wouldnt be down near the bumper, it would just be a tube from the bumper to just infront of the intake.

The M2 CFI setup (and the M2 IC) keep water temps in the mid 80's with air temps super low as well. I haven't had a chance to really see a Hot Summer day (just bought the car in Nov) but from what I have seen a shielded intake with ducting from the RAD and a better IC make a WORLD of difference.
