Default Increasing torque at lower rpms

Having torque at lower rpms ensure safe overtaking. Its sheer pleasure to have it between 1500-2500 rpms.

Can anybody suggest methods to increase torque at lower rpms without major alterations.

From the profile it is Fiat Adventure, It does not surprise me as I have similar question about my Petra 1.6.

Improving any engine figures will never really be a bolt-on experience. You can try with the usual performance air filters and FFE. With these 2 done right, there will be a slight upping in the engine figures - felt primarily at higher rpms - not always lower. Iridium plugs dont do squat - they're only meant to operate under higher temperatures as in a turbocharged engine.

Get a turbocharger as an ultimate solution to your low-end/any-end torque woes.

Another unique thing that will work: get a remapped ECU to fire all injectors simultaneously rather than sequentially - as in stock. You'll NOTICE a difference. But the mileage will drop atleast 35%.

Free Flow Exhaust can really improve the low end torque....
I've driven Zen with Automech FF exhaust , the torque at low rpms was more than the stock car i drive.....

Lol where did that come from?? A TC means Turbo Lag and loss of low end drivabilty till the TC kicks in.

True .. I think he got confused by SC .. Unlike TC's they dont have lag ..

yes, it is an adventure. To go for turbo is not feasible, due to various reasons. Does porting and polishing helps to get better torque at lower rpms.

Air filters i think will make in gear acceleration better.

Air Filters also increase the low end torque slightly and so do FFE.

air filters along with free flows should help for starters, if not move to porting and polishing coz they are expensive/delicate and ir reversible job

As per many tbhpians ffe in a 1.6 is not highly recommended. They quote complaints sprunging up. And if you inspect underbody of an adventure you can understand how much twisty is the exhaust layout. Even straightening them itself will give more power, but it ill be a hectic affair.

if the above said pipe is coiled, a straighter pipe with only one end can will improve throttle response immensely and no this wouldn drop FE though FE might suffer with more enthusiastic throttle control
