Borg Warner S300 on the Dyno

I'm sure his dislike for twin-scroll can't affect the rolling road LOL.

But he will tell you how crap they are against his HTA versions lol.

GTX35 on a 2.3lt engine


EFR 7670 on a 2.2lt engine

This is S200SX and EFR7670 and then a GT4088, You can compare the GT40 and 7670 to the 8374 graph on here as they are the same spec engines.

I haven't got an Evo, so it doesn't really matter what he tells me LOL.

Here is a Evo on a EFR 9180 at 1.4bar boost.

You seem to do alot of evos mark? So which engine do you prefer? Evo or Cossie ?

How come your using a 9180 to produce 600bhp wouldn't a 7670 be better spool up and still get the same power?
Or is there more to come?

The clue is in the boost this thing will be running up to 2.5bar, My aim is 720hp at what ever boost it takes I think it will do this on 2.2bar.

Funny to see a 9180 spool like a gt35. No doubt this is a leap forward.

[ksa-cossie]

So which Borg would be good for 450ish bhp ?

[mark shead]

What did you have to do to the 2wd manifold? How much later is "later" or do I have to wait for the graph (can you get them to overlay the two to see the difference) ?

If you tell me what mode to get Gary to put their DD in and what gear to use, I can replicate the run on my car?

Mike do you know when you will get yours on the rr.

I haven't got it back from having the diff fixed yet. This is all done, but I've asked Harvey to set up the closed loop boost control on the T6, as it seems to loose a bit of boost when it gets really hot.

That 9180 graph ive overlayed against my RR graph using the GTX 4202 is that fair to show the difference in spool if so i will post it. Its spooling 1000rpm earlier.
I could also post my Dyno & RR graphs overlayed to show Mike just how much later it spools on a RR compared to a static Dyno is about 1000rpm.
