Default 734 rwp @ 1.6 bar. 3.1l 16v turbo

Hey guys, long time no see.
Here's the dyno from my latest engine setup in my race car (http://www.facebook.com/RevlineTimeAttack)

734 rwhp at 1.6 bar.
Top thin line is torque.
The next thicker line is boost (reads a bit high)
Then it's HP at the crank
Then RWHP
Then driveline losses.

Modifications? All of them

I think social media has just about killed this place.

Nice to see you though and great job.

WTAC 2019 still on...?

which is a shame, because the FB groups are for the most part useless and full of retards asking the same 6 questions in an endless cycle.

That's incredible power considering the engine size and low boost!

I know you're in a competitive environment, but any details you want to tell us?

Great results Gustaf!! Looks like you wound it off at 7k but I'm sure it would keep making power.

Best of luck for the upcoming season.

100% agreed. Plus it is quite difficult to simply read or follow a "thread."


Anyway, all I can say is that dyno chart is impressive to say the least. Do you have any links to a website or past post that lists your modifications?

Incredible results - congrats.

Where does that put you in terms of weight/HP ratio?

Didn't think it warranted a thread but I had been reading up on the 190e Mercedes 2.3L twin cam engine of the mid 80s because it parallels closely my engine formula for the lightweight 2.5 16V I am building. While the stock 944S 1987-88 only was pretty impressive, I wanted to investigate what kind of results a specialty engine company like Cosworth could wring out of the same bottom end when Mercedes commissioned to build the head/header/cams.
In a streetable version (talking about Mercedes here), they managed to equal the Porsche 944S numbers @ 200 less ccs, years years before the 944S.

Reason I brought this up as background of this latter point, Mercedes took the displacement out to 2.5 liters and Cosworth further developed this engine to 202 BHP dubbed "Evolution I" then 235 BHP "Evolution II" raced in touring car series.
Mercedes/Cosworth deemed it necessary to modify the blocks, with "extra enforcement ribbing" just increasing power a meager 30% over it's original design intention.

Hi Patrick, in the end we were so pleased with the torque curve that we didn't feel we could gain much by playing around with the cams from the current setting.
The new engine will likely make power to 8000-8500 rpm so it should gain some nice power just by allowing the engine to breath higher up.
But we're close to the limit of the EFR9180. It's really not a 1000 hp turbo for big displacement engines.

But I'm chasing cooling issues that have followed the car since several years. I'm now leaning towards stock water pump cavitating with the setup in the car.
Looking at pics from your Meziere installation! Likely to go that route during winter.

Car is at around 1080 kg without fuel/driver. So it's quite the thing to drive

Yup, it is ashamed.

Pelican's about the same.

Never had a MySpace, don't have Twitter or a Facebook account and never will.

I don't even run Windows on my personal PCs, Linux only.
