Bringing up the Torque?!

[TRD_07]

I'm not 100% sure if any cams are in development but wouldn't a cam be a good option to bring up the torque? I wonder how a cam would work with say Avo stage2?

Then you need to swap for a diesel engine. No one will ever do it but it's true.

If anything youd swap cams to gain more power up top. Same torque more power

I have multiple friends with BT 1.8T's, even the one with a built engine, standalone and GT2871RS doesn't make low end power like stock. It has better low down power than the guys with T3/T4's but it still doesn't spool at 2k rpm like stock does.

Post your dyno though, show much low end torque a BT 1.8T can make.

well your right about having no power at 2k. I just meant i didn't have any lag while racing. street or track. but ya on this dyno starting a 4th gear pull hell yea your gonna lag.

And this whole thread is about making more torque down low, so how exactly does a BT 1.8T have any relevance?

The OP wants more torque than hp, which means all of the power is well below 5252 rpm.

I didn't bring up 1.8t in the first place

[subatoy]

why wouldn't lowering compression ratio help with the torque?
I know high revving means less torque and high revving is the nature of high compression engines.

[wparsons]

High revving doesn't mean no torque, but you need the engine to breathe properly at the target powerband RPM range. You could probably get more low end torque by changing cams, but you'll lose A LOT of power up top by doing that. Without physically different lobes like a VTEC engine (or VVTi-L) it's always going to be a compromise.

Reducing the C/R (and/or redline) will bring the HP and torque numbers closer together, but it won't be from increased torque, it'll be from decreased HP.

This engine makes more torque across the board than the 2.0 8v in my old Jetta, and that engine had similar hp/tq numbers (~120 of each).

Anyone willing to drastically sacrifice top end power for a bit more power down low should really re-think why they bought the car in the first place.
