Bringing up the Torque?! - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

subatoy · 06-20-2013, 01:34 PM

Apart from adding FI what exactly would make the torque raise?
I'm assuming bringing the piston ratio down to like a 9.5:1 would do the trick and raising the boost?

Crawford performance built a BRZ that give 400ho and 500lb tq!
These are the ONLY figures I've seen where the torque is higher than the HP figures.

so what components exactly are needed to make the torque figures be higher than the HP figures?

You answered your own question, BOOST. Apart from some form of forced induction, nitrous oxide or increasing displacement you won't see a drastic increase in torque figures. In fact some N/A mods actually decrease available low end torque. Crawford's has numbers like that due to a small quick spooling turbo, rumor has it that the car is pretty dead in the upper rpm range when compared to other turbo kits on the market.

I rephrased my question.
I'm looking for torque numbers higher than the HP numbers just like Crawford performance's car.

Why not ask Crawford yourself?

I searched for them here but couldn't find them and their emails I found on their websites don't work.

HP is related to RPM and Torque. The only way you'll have more Torque than HP is if you lose Torque after 5250 rpm.

If you want more Torque than HP, get a small, quick spooling turbo that'll give full boost down low and then start losing boost near redline ...

We have a 7500 rpm redline already and some people have bumped that up higher already on the stock valvetrain, there is no reason to seek more Torque than HP, that just means you're choking the car on the top end

And I really can't see a way of one of our engines making 500ft/lbs n/a.

Quick google search, right in their page...

Also,
@pheoxs beat me to it, great explanation!

those are exactly the links I click that don't work.
I can't call them as I'm outside the US for a few more days.

you mean like a GTI? I would take a GTI torque feel over one of a high reving-low-torque engine. There's simply more power everywhere for real life conditions.

Ok, I was referring to the phone number

PrDarkKnight · 06-20-2013, 02:03 PM

it has to do with the fact that they altered the compression ratio by changing the internal to withstand more boost. e.g. N/A cars that are high compression tend to lack in torque and have a fairly high RPM limit and low compression cars tend to be in the same HP/TQ figures and have lower rev limiters to achieve max power. My .02 hope it helps

Why though?

Why seek more torque with less HP when you can use a properly sized turbo and have the same amount of torque but hold boost to redline and get more power.

The 1.8T/2.0T power you are talking about is probably a flashed car that boosts to 20lbs down low then tapers off to ~12 by redline, all low end power and no top end. You know what they usually do for mods? Swap in a larger turbo (K04 etc) to make more power and hold their boost to redline.

Why you ask? Because there are people that dont mod
Cars to win races, simply to enjoy the feel of it. I had a 370z that felt slower
Than my completely stock Gti due to toqrque delivery.
I'll take a butt dyno over real dyno any day.
