Has anyone ever had a problem with starting there car with a 4 to 1 exhaust right nxt to there starter motor?My starter motor is short in length and its sat right nxt to the exhaust manifold I think there is a couple of mm gap between them both.When its cold its fine but ive noticed the car warms up rather quickly with this manifold on and when it gets red hot in the engine bay the car wont start again.Seems a silly question but worth an ask

 

Starter motors don't like heat.
Get the down pipe wrapped.

 

Cheers I will do.Ive been wrecking my head for weeks.Im letting the car cool down just now.i will try starting it again later and if it does I no where I stand.Is there anything else I could do to aid cooling

 

What car is it?
And how hot is red hot? Is the coolant temp high?

 

Its red hot the 4 to 1 manifold plays a big part in it.The gauge doesn't take long to reach temperature.i can bend my earth cable when it gets hot as well lol.i don't think bonnet raisers are gonna help on this one.Its a mk4 fiesta but ive fitted a 2 litre blacktop in it

 

Hot manifold could be a sign of running lean/too much ingnition advance.

 

what he said
but it was a common problem with cvh's years ago, but not to the extent your experiencing

 

I will wrap things up and see how it is then

 

The other thing is my battery lives in the boot and im using 4 gauge amp power cable should I be using anything thicker

 

Can you not fit a rear starter gearbox?

 

Hi I do plan on fitting a rear starter gearbox at some point.
