Increasing Performance of the H6

[Tradewind]

Most of the SC 3.0s are making 210+kw at the tyres no matter where they are measured around the world - many countries, different tuners etc

That is correct... That's basically the guaranteed number for s/c h6 (obviously not on an unhealthy engine, don't get me on a technicality). Exciting isn't it when you've got that base figure and then you add E85!

My bad

Sorry guys I don't know what I'm talking about and obviously don't know enough about how amazing the h6 really must be.

330awkw seems logical and realistic from 15psi on an unopened 3.0 litre on 98.

How much power did Justins TT H6 make on Inights dyno on 98 and it makes more since the retune on same boost still on 98.

That 330Kw car is on E85 since Darren has been running E85 since before the 2nd hand AM Auto turbo kit was purchased... Runs 8psi normally

[KiDo_Tuning]

3rd gear, peak power at just over 100kph... from memory, 3rd gear normally revs a bit higher than 110kph

So say 50% more rpm(6600rpm) and say 20% less torque is 360whp.

Re: justin's - you're not seriously comparing airflow and charge density on a twin turbo h6 to supercharged one are you? 9psi through two 45lb/ min compressors is NOT the same as 9psi through a belt driven supercharger.

223kw atw is impressive on 98. So why didnt it make 360whp?

Why speculate when it could have actually done it since it was on the dyno?

[vertix]

To clarify, those dyno sheets show e85 right(especially as it's hand written on twice)? Also the boost levels look like that is clearly a full RPM run?

If so, doesn't that just show 223kw on e85?


Not trying to have a dig or anything, just trying to clarify what that data is representing.

Do you have any graphs and specs from bianca's 2011 ez36?

AZ back in 2006 had a 40R running 14psi through a ez30R = 300+kwatw (ie98 and no e85)
was very exciting in a Gen2 RX that looked like a shitter.
that was rods/pistons/sleaves/bearings/headstuds.

Someone needs to put 20psi through a setup like this in a daily!!!

+1
it will come eventually mate, I'll never sell mine and have plans to fully forge the engine in the future. I want to make 400kw atw on E85... And before anyone shoots this down, I just want to say this will be no expense spared. I WILL make this happen eventually.

This is a G dyno chart 237kw at wheels - 3.0RB. I think this one has K2 headers and other goodies in addition to the SC

Unfortunate you can't see the torque numbers

I'm all up for getting proper power out of the H6 and have already purchased a second engine to use for the closed deck build to achieve over 500bhp. The main issue I have with sc is that whatever I have tried to do to increase the boost it remains at around 8 to 9 psi when theoretically it should be running 13psi and the other uk equipped car is also having the same issue.

l haven't given up on the sc route and I am looking into alternatives but i have a feeling it can't quite deliver on what I'm hoping to achieve.

Yeah I'll be going for a big turbo set up to push past 350-400kw on a built engine.

I honestly could not care less about a 'number'.

I want to make 400kw atw on E85

Looking forward to your build man! Hope the new place works out better than your last engine builder.
