Getting a new front bumper....

[hmltnangel]

just thinking......

if i was to replace the bumper then obviously a new intercooler and radiator will be needed too but on speaking with my local fitting joint they weren\'t sure about the right setup....(not an rx7 specialist so I though I\'d ask everyone on here first)

apparently on an rx 7 putting an fmic on the car then the radiator behind it could cause problems as the ic could disrupt the flow of air to the radiator. Needless to say I don\'t want to overheat the engine. What would everyone reckon as the best idea? From looking at the FEED bumper I reckon either way - cos it has an intake right in the centre of the bumper for either one. I was thinking a new aluminium radiator mounted at the front then an intercooler bahind using that lovely intake cut into the bumper.

Anyone else agree or would you lot have it the other way around? Whatever way what ic\'s and radiators would you recommend?

Again I have ideas .... was thinking of the fluidyne or the koyo radiator and either the blitz ic or the one from //www.shaneracing.com the replaces the standard ic.

all your suggestions welcome.

cheers

there is a thread at moment about fmic or charge cooler..never heard of anyone placing icooler behind the rad..doubt anyone makes a kit that does it this way anyway..u have a few choices
v mount and new rad some swear by this but defies all conventional tuning logic as intercoolers in engine bay will allways suffer heatsoak/
chrge cooler is good idea but if pump for water packs up while u are booting it and u dont notice then intake temps will soar
i prefer to stick with fmic and larger rad and then look at getting water temps slightly lower by either different thermostat/purple ice or water wetter
on the road fmic shld not cause any cooling probs with larger rad as boost is not sustained
on track however this may well be a different story.best to think about what use ur car will be getting before spending ur money
speak to one of the tuners..geff at re worx uses charge cooloer but his is a 1/4 mile car and charge cooler is better suited for sitting on the line as nil airflow but wnen running on the road a fmic will get cool air all the time ur moving

Charge Cooler?

Well the car will mainly be used as for cruising around in - some sitting at the quarter mile occasionally. Mostly to show off. Def getting the FEED bumper - it has an extra air intake on the middle of it that could be used for sucking air in towards the radiator or the IC depending on what\'s at the back.

What IC would people recommend? I\'m kinda leaning towards the dragon radiator now. so thats half the battle.

Also my car has the twin oil coolers in the side air ducts at the front. (least i think that swhat they are) what would I do with them?

[rx7veilside]

dont touch the twin oil coolers as they are fine.it really is best to speak to maybe on of the tuners ie re worx/wgt/carl if mainly road use then intercooler/if track and 1/4 mile the charge cooler as smaller rad for charge cooler and more air for normal rad.chrge coolers are a good set up but as i said if pump goes u are up the creek as nothing to pump the water means excessive intake temps.reason people go for front mount icooler is the air is free and hits the intercooler first.but is is expensive as intercooler plus radiator etc etc.a rad and v mount is also a pricey set up both these set ups are prob near on 1500.00 plus fitting..charge cooler would be approx 8-900..nothing is cheap when tuning

[hmltnangel]

so not to seem stupid and ask really stupid question but what is a charge cooler?

[rx7veilside]

basically it comes off the turbo same as intercooler then a cylindrical tube with a core that has the intake pipe thru the middle leading to the plenum and a kind of radiator set up round it.the water is pumped thru the rad at front of car then water cools the intake pipe and flows back to the rad again cooling the intake constantly even when stationary...not very good explanation but imagine a small exhaust box with a pipe each end one attatched to the turbo and one the plenum then add a rad and water pump to flow water round the inside of the exhaust box

[hmltnangel]

sounds like a great idea........ think i\'d want a new water pump though..... just in case!

What would happen if you had both? a small fmic or even an smic and the charge cooler?

Best of both worlds or making the air too cool?

The charge cooler water is not part of your engine coolant it\'s a stand alone system with it\'s own elect/pump. look at PWR in ausssie land they are the kiddies. Kit can be purchased in uk from Geff at Reworx. I\'m fitting one at the moment.

[scooby_si]

silly question but are charge coolers also known by another name only when i tried searching originally on the US forums there was booger all, maybe they\'re just behind us for once lol
Si

[hmltnangel]

me too!!

though as far as I\'m aware they are just essentially just water cooled intercoolers! If someone had said that to begin with then I\'d have known exactly what they were on about! They were commonplace on the MR2 forum when I used to have one. People swore by them because the 2 has a crappy airflow to the ic! SO DO WE!

I\'m gonna try searching for them under INTERCOOLERS tomorrow.

For now though folks...... I\'m off out to the pub and hopefully i\'ll be finding some nice chick!

see i was right......hehehe!

water to air barrel intercooler!

[hmltnangel]

must.....get.....to.....pub!

This is the system that Geff at Reworx is running on his fd and it\'s keeping his turbo supplied with cool air. He ran in the 10\'s. But his fd is fatter now over 500bhp at the rear wheels. RESPECT.:3gears-lh

[hmltnangel]

how much roughly were they?
