I'm told by some "experts" that if I do a stage one upgrade on my 2wd cossie without upgrading the intercooler or fitting a chargecooler then my engine is at great risk of going bang. Is this true or bollox? Any advice most welcome.

total bollox i was running stage 3 on mine for about 10k till i got a 500 cooler (running stage 1 on oe for about 4years before that(do the head gasket though)

Yeah the cooler will be near its limits at 300bhp/ stg3 warm ACT`s etc. RS 500 style would be better but a std I/cooler will be fine, if bothered then a 4x4 I/cooler will fit and help cool the air more on your Stg1 and good for 330bhp maybe more .

mrjonnie

I've got Grp A head gasket. Thanks for the advice. Hoped it was bollox, will listen to better informed people, like on this site in future.

why do people give out info with no idea prob thaught you were on about a vauxhall engine should run 4ever on stg1

it's not total bollocks, but it's not totally true either. if life was always black and white, it would be pretty easy.

the point is, the more that the turbo compressor compresses the inlet air, the hotter it gets. that heat needs to come out as it flows through the intercooler, and obviously a bigger intercooler gets rid of more heat.

if you don't get the heat out and have high temperature air being sucked into the engine, that inlet charge when mixed with the injected fuel is more likely to self ignite rather than waiting for the spark plug to light it up. that's bad, mmmmkay.

also, the time required for the mixture to burn will be less compared to a cold charge.

the weber ecu is programmed to measure the Air Charge Temperature (in order to estimate how much mass of air is going into the engine, along with the MAP), and if the ACT is high, the ignition timing will be retarded.

a retarded ignition reduces the power output and reduces driveability, negating the effects of the upgrade in the first place. at the very least, why not upgrade to a 4x4 intercooler for the sake of the 50 quid that they cost secondhand these days?

You never get a short answer from foreighnRS

could be a bad idea as there is some real shit advice that i just cringe at when i read it.

find a tuner/specialist that you are happy with and go from there, everyone has a different opinion on how to do things

mrjonnie

Thanks people, would the 4x4 intercooler make much difference as I've not seen one and don't know physicaly what the difference is?

4x4 is just a bit bigger but every bit helps

True, find as tuner your happy with and follow their advice, saves expensive mistakes as you pay for their experience/mistakes

For a stage 1 tune...it is utter bollocks m8. Going up to nearer your average stage 3 tune then yes, it would be a good idea to up grade you cooler, and turbo. The stage 1 tune is considered by most to be how the car should have left Fords gates when new. Its a great conversion that gives you a hint of the potential of what is actualy hidden under your bonnet Do it!!!!

Just make sure you use a top tuner and not an ebay special job lol
