Full fat Stage 3 setup

[MY95]

Bryns was a long time ago don't forget, the tech has come on since then!

Big difference though Tom, Bryn's was newer at the time, spent tonnes on AMG injectors etc, was rebuilt and had a lot less miles! There isn't any difference in the HDI90 engine though between BRYN's and Dr J's as standard.

Id go by what Whippy says, 185bhp does sound about right for maxxing the injectors, 200bhp I think will make the engine shat itself id think, especially if it hasn't been rebuilt, Bryn's 230bhp one didn't last long and that was rebuilt IIRC, and I think 320lbft will give you gearbox and probably even paddle clutch issues too. Could be very costly for you replacing parts, and unless they are new, the used parts you buy may only last the same time as the failed ones. If it was me id enjoy a reliable ish 180bhp/300lbft and see how it goes for a bit before going any higher, but its all trial and error I suppose, otherwise no one would learn about these engines and gearboxes etc would they.

Clutch is new and gearbox a low millage as i recently shat a clutch and diff from a box. My stage 2 made 146bhp and peaked at 290lbft with a few issues.

I really am expecting to pop the engine as shes 211k and a daily but we shall see. As you say its very much trial and error.

Good on the gearbox side of things then, adding another 40+ bhp may come as a bit of an issue though, especially seeing as yours is at quite a high mileage already, especially to be going stage 3. But yes only time will tell what happens, good luck with the project and I look forward to seeing some updates
