A challenge for all the tuners out there? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

ft_sjo · 03-15-2013, 06:00 AM

So a friend of mine has been tuning engines for quite a long time. He's been my mentor over the years and what he produces is quite impressive.

I am curious to find out if any of the tuners or 'tuners' on this forum would be able to replicate the results he has?

For example, below is a superflow engine dyno graph for one of his 2 litre engines. No VVT, no direct injection, single scroll turbocharger, pump fuel (97-98RON). You'll notice over 300 ft-lb from ~3500rpm and a fantastic torque curve. Some more detail, 7.5:1 SCR, T3/T04E type turbo, journal bearing.

I've never seen anyone produce a torque band as good as this on a 500bhp 2L engine. I'm hoping that some of the BRZ/86 tuners are capable of attaining this? This is a serious question. Who can do it?

Answers on a postcard.......

I'm no tuner but I'll give it a go.

Lemme just find my ruler around here somewhere...

I think has to do with the cams being sized correctly for that powerband. The FA20 holds nice torque from 2500-6500 (with a header lol). If they were to size the cams to boost the VE above 6500 (at the expense of low end), you theoretically COULD attain that power band with a properly sized turbo. Holding a power band for 2000-3000 RPM isn't difficult.

Looks pretty close...

The innovate dyno looks exactly like this, done.

OP's dyno looks like data points were taken every 500 rpm and a straight line was drawn between each. If that is the case the chart is misleading and a poor gauge to judge other charts by.

pff, you call this a challenge?

I love your napkin dynos @7thgear

Great VTEC after 20,000 RPM. Should get a VTEC controller..

7thgear · 03-15-2013, 12:36 PM

and that's just in reverse!
