AAARGH! Intercooler/Rad help...(sorry)

AshRX · July 22, 2009, 12:51:53 PM

Go for a Twin Spark as for one it will ease your mind that you wont get ignition breakup at top end as long as your plugs and leads are in good nic.

As for rad - yes get one, the Koyo has a lot thicker core so will bring or cause water temps to stay stable.

The ARC intercooler is a very good intercooler and in my opinion better than the Greddy one. As said above ducting is the key. You could have the best SMIC in the world but if the ducting is wrong then its pointless having one.

What plugs are you running on your setup? Also you dont need a 044, just dump a Supra pump in and that will be fine for the twins. One way of checking is looking at your fuel injector % on your commander to see what max your hitting on full boost and then you can work out which pump you need. Your running a good FRP so you have no worries at the moment with fuel pressure to the rail.

Cheers mate, the Twin Spark looks like a nailed on certainty then. I shall add that to my list lol.

As for the ducting, the ARC intercooler uses the stock ducting, thats one of the reasons I bought it. Is there a way of making the stock ducting better?

I havnt got the upgraded fuel system fitted yet, so wont know the % values until its being mapped. But like the Twin Spark, is it worth me going to get it mapped only to find that the pump isnt up to the task. Effectively wasting Â£300 on mapping when a Â£100 pump could have been installed?

Hmmmm....its all things to mull over.

AshRX · July 22, 2009, 12:59:29 PM

rip the standard ducting out and build your own dude. The standard ducting on the FD is pants

If your worried about the fuel pump just get a Walbro or supra pump. 044 will probably be a waste on twins

trevtubby · July 22, 2009, 01:02:08 PM

lol, how easy is that to do?

Any pics/how to`s etc of people making their own ducting?

As for the pump, I hear what your saying...but, a walbro or supra pump will probably cost about or near as damn it the same as an 044, plus when it comes for me to go single...i`ll already have a pump up to the task? If that makes sense.

AshRX · July 22, 2009, 01:03:08 PM

speak to CharlieP on here dude, he made his own for a SMIC

Grizzly · July 22, 2009, 04:46:26 PM

Out of interest does this look like your Ic? I only ask because there is a newer version of the Arc SMIC which is very similar to the Greddy one, but the old one is Dodgy (was told its a stock core with alloy end tanks

)

Also i know what people are saying about fuel pumps but if you ask me the Bosch is the way to go.. look at it this way its German so its Over engineered and will never break down

plus i know guys that have been using them in Cosworths with 8 injectors for years at the upper levels, they go on faultlessly and will do what ever you wish of them.. For me i wouldn\'t use anything else. No i don\'t work for Bosch..

trevtubby · July 22, 2009, 04:48:51 PM

Yeah its that one?

mph_saab · July 22, 2009, 05:02:28 PM

I have a brand new v-mount going cheap if your interested mph@uses.co.uk

Grizzly · July 22, 2009, 05:05:37 PM

In My Opinion this is the daddy of SMIC\'s, its the PFS (Peter Farrel Supercars) i put this pic up so you can see a well Ducted IC

Grizzly · July 22, 2009, 05:06:28 PM

Sorry but yeh you need an Upgrade, that one is not much bigger than stock.

Out of interest, when you say you have uprated Twins what have you had done?

Well that sucks lol.

Oh well

GhostWKD · July 22, 2009, 05:19:32 PM

thats the SMIC i have ready to go on also :o although im still on standard twins with induction/decat/apexi pfc etc

Is it a worthwhile upgrade over a standard intercooler or am i just wasting time fitting it?

trevtubby · July 22, 2009, 05:21:00 PM

Its helped with my temps quite a bit mate since fitting it, its great for stock twins with minimal mods. I think its just when you make that next step it sounds like it wont be up to the job.

Boo

Grizzly · July 22, 2009, 07:03:43 PM

Depends what your doing with it, if you are running twins in the mild end of the range it the Old Arc will be fine. There are things to make it work better like rigging up some decent Ducting etc.

davyv · July 22, 2009, 08:47:42 PM

Trev when i took the turbos off i was using an Apexi GT fm intercooler/ Ron Davis rad which kept water and air temp down .
