GR Yaris Expected Power Gains?

[shogunzac]

So?
How did it turn out?

Collect it tomorrow pal, had a phone call yesterday to say they’ve finished all the mechanical side of things.. Dyno is now the next thing

 

[WRC6165]

Looking forward to it

 

[shogunzac]

Just had a call from Litchfield 350bhp I’ll post the graph later on when I’ve collected it…
It’s a cold day here in UK 0°c but still, I’m really pleased!

Thats nice! Did litchfield measure it on their Dyno before installing the parts?

Lots of smoothening happening there, but that's my near ideal torque and power curve, very wide 400Nm available and a nice increase of power all the way to the redline First one.

Please report on driveability

PS: very low intake temps, budget for an IC come summer if you want to keep those numbers....

This is a good result and a smoothed out curve but no answer to my question
I ask because every dyno is different. It is therefore best to compare the before and after results on the same dyno.
Mate of mine had his GR on a Mustang AWD Dyno. Mods: Milltek resonated, Wagner IC, modified Forge intake, 298hp /398nm Stock and 321hp / 460nm DTE V2 Racing box. The question is how seriously you can take these results. But at least you can compare them.

That seems very high power on stock ECU with those mods....

Edit: Mustang is known to be optimistic....

That's what i thougt. Maybe I'll put mine on the same dyno and see what happens..... it says over 400nm over stock.

Considering torque is reported low, power has been corrected down for the low intake temps and the fact that the shape cannot be faked (unless it is actually faked), I have no reason to suspect it's unrealistic.

 

[Max]

I don't think it's unrealistic at all, but for comparison purposes it would be ideal to have a baseline measurement

Here’s the rest of the info on the Dyno…

Wow brilliant. Do you mind saying how much that lot cost?

 

[WRC6165]

Great result.
This is mine from litchfield with the cams but I have a HJS sports cat.

Personally I don’t think the cams are worth it.
The car had more power and torque without the cams until 6000 rpm, ok for track car but not really a road car.
Also pricey for the cams.

My stance is, if you want in gear acceleration, buy a 340d or something. 450Nm+ whatever in a 1.6 is pretty nuts, much prefer a car that rewards revving out and it is not like 415Nm is lacking.... But different tastes and all that

 

[TTomas]

What is the maximum boost with these 350hp+ Litchfield engine tune?

A lot....

What is the maximum boost with these 350hp+ Litchfield engine tune?

interrested in boost curve too

Can’t speak for the litchfield tune, but mine made 350bhp with 1.7bar peak tapering to 1.5 bar.
