its overheating, now how to help it?

Fuel filter? Was an issue on one of my old cars and had similar issue....

I'm not to sure if the factory fuel lines which would be setup for 1300cc carby would be suitable for a 2000cc turbo? would need double the fuel flowing through it almost... but I guess if it dyno'd ok then should be fine.

[S0LJAH]

nah all fuel filters are brand new
less than 2000ks on them
and i assume it would be all the time i.e everytme i try put it under load

this is definately related to giving it death for an extended period

Are you able to put a wideband on it so when it pops you can log it if you are leaning out...?

[MrBishi]

Coil packs heating up causing misfire under load? Coil on plug?

[S0LJAH]

nah factory wasted coil
from what i think i dont think it is due to the fact it sat on the dyno for a good few hours solid with no issues
where i imagine the coils would have got there hottest

and when i do have the problem it fixes itself relatively quickly if you just let it idle
i think temps would take a bit longer to cool down especially if your still running the engine??

[benny]

my bet is ignition related ... it sounds like the spark starts breaking down and you let the coil/lead/plug/ignitor cool and your good to go again..

[S0LJAH]

ok cool so they cool down quite quickly
i take it its the continuous sparking at hi rpms that cuases it to heat up rather than the engine bay temps?

and at idling it fires slowly enough to cool down?

anyway i can test it?
what part is most likely?one of the coils?ignitor?

its got brand new plugs, 10.5mm leads

stock coils and ignitor i got with the intake manifold

hahahahaha i fell like a newb now LOL

turns out its hitting a temp realted rev/boost cut
basically turns the car into limp mode and wont let it rev past 3500rpm or 1lb of boost

anyone got any good ideas on how to keep it cooler during burnouts etc?
my limit is 110deg but it seemed to be cutting out around 95-100deg on my seperate temp gauge
guna go into the tuners and get them to check the limits and see what the temps are actually doing

ive got a single 14inch fan mounted flush to the 3 row radiator
it works awesome at all other times just burnouts its no good

im running the line out of the the rear of the waterpump round to one of the outlets on the bottom of the thermo housing, would this be sucking heaps of hot water back into the waterpump?

[FST4RD]

Maybe another fan? 2 x 12" fans instead of 1 x 14"?
I have not sure.. just throwing some ideas out there...

[S0LJAH]

nah wont fit 2 12s across it unfortunately and i cant fit one on the front either

i though of making up one of these



but not sure how effective they are and how much my cooling while driving will suffer?

[JD_Stazza_Brendan]

A good radiator shroud will improve cooling.

[TOMSUN]

I have head that if you run 100% water you will have the best cooling capacity. Anti freeze retards the ability to cool.

So run 100% water when doing burn out comps, or what ever your doing then put your coolant back in for street etc.

Pop the back of your bonet about an inch with spacers (or better still take the bonet off)

Get water jet spray onto your radiatior when doing burnout. The evaporation will help cooling.





What car and motor is that???

And pics of burnouts!

yeah if you don't use your headlight squiters plumb them to spray onto the radiator :beer

only if you're in europe, over here its anti freeze/anti boil, it raises the boiling point...
