Need more torque, what can I do?

RallyRS · Post by **RallyRS** » Tue Mar 14, 2006 12:38 am

Hi,

I race my legacy in rally and its bogging in tight corners. I'm trying to left foot brake to keep boost up but not going so well.

I have replaced the air box with a pod filter and run a 2.5" mandrel bent exhaust with no mufflers. Maybe this has lost me my torque? Seems to be dead below 3500rpm.

I have a VF8 turbo and it hits boost around 2500.

I also use a eprom chip in standard ECU which seems to run abit too rich everywhere, I think it might be getting to much fuel sometimes???

Close-ratio box, anti-lag and stand alone ECU would help, but I need some more cost effective options.

Cheers
Hayden

my car also seems to run a bit too rich in all rpms, and mine does like to bog down also. i think u should check into that.

i dont think there is any way to up your torque without spending a lot of money.

as you said, you could do these

Close-ratio box, anti-lag and stand alone ECU would help, but I need some more cost effective options.

but that would all be expensive IMO. sorry i couldnt help ya any more.

Want more torque, up the boost.

that wouldnt help much with low-end torque would it? i think thats what he wants. maybe im wrong.

When you remove stock, restrictive intakes and exhaust, you usually sacrifice low-end torque for more up top.

I don't think freeing up the intake or exhaust really hurts low-end torque on a turbocharged vehicle. I think it just increases top end, and the change makes the bottom end feel like it lost power.

IF you are running too rich down low, its a definate power killer.

I actually wasn't even thinking about turbo... that makes sense.

Incorrect

If you do a lot of corners at relatively low speed, might you do better with a more spoolable turbo? A VF10 or TD04, for example?

What you suffer from is small displacement. I hate the 2 litre. Im forced to drive USDM WRX's all the time, and I just want to vomit all over them.

You need ignition timing my friend. Thaty'll gain ya some low end and spool up.

2 Step limiter what?!?

Buy a new engine.

Really.

No replacement for displacement.

Thanks for your tips! All useful apart from new engine.

I think there is no cheap/quick answer. I need to get the wallet out and spend some money, again!!!

I good tune on a 4wd dyno with a stand alone ECU would be best I think??? maybe some anti-lag. Practicing my left foot braking everyday so that is alway hoping.

Better start saving.

Thanks for your help.
