I see.

 

Are you not going to put it on the Rollers before you throw all this money at it, just so you atleast know how much of a difference its all made.

 

Unless youd rather not know?:search:

 

Unfortunalty Axle i think your a bit behind the times with the Matt H saga. Matt's engine set on fire a few weeks ago so I would think the BHP is roughly and this is only an estimate 0BHP ;) However before the fire and in the beginning the car produce 410BHP on a Rolling road day at Hyper and that was with 440cc injectors + hybrids etc. On that day I was in the dyno encloser and saw the dyno trace map for the AFR going all the way down to 13.5 afr @ nearly 1.4bar. Which is obviously dangerous for the engine. Unfortunately Matt push it a bit hard shortly after that and melted a Piston :(

 

Then the car went to TF for a engine rebuild then came back up to Hyper for mapping as Matt had got new (hybrids on long story) 550cc injectors and a EMB. The engine then produced [email protected] :think::confused:. However to my mind and IMO I can't see why the car was producing more power! as the map if you can call it that did not include any "mapping" above 3000rpm and the car ran 10 afr or potentially lower. Even at 1.4bar again looking at some dyno print off i saw at hyper whilst Matt's car was in there.

 

So TBH I would have though that the original figure of 411bhp was due the lean afr and now it was running a much safer 10 afr (although a tad to rich IMO) but still using the same boost pressure, dyno etc so I would have not been surprised if the figure would have been less. I wonder how "tweakable" the dyno was at Hyper :eyebrows:

 

Anyway its all in the past now!

I went 6 speed for strength but I do miss the auto in traffic I have to say

 

My last car was a BPU+ uk spec, and I miss the autobox in some respects (around town, effortless overtaking on the motorway etc) The power delivery of a manual single is completely different, but more involving and rewarding.
