1 degree retard is roughly 2 bhp.

intake air temps are one thing , don't forget water temps also change the timing

That are IAT's from a Harrop SC on the track...  (but my M62 is not much lower!) Water injection to the resque.

Will see some proper power figures in October when we strap a few Dutch SC's on the dyno.

I could do with some real heavy runs, when I get the alternator problem sorted, but looking back on the logs I did after I got the fans turning the correct way   max inlet temp I show was 68C, Helps not heating the laminovas up from the main rad. I run with an inlet spacer, turbo ears and a large gap on the diffuser, might help disperse some of the heat. 

 

I have now set up ready to go a water injection system just want to get the car running first, then will try pumping water at High rpm

 

water temps for me were fine 90C but yet again I need some REAL driving to check it out

one step back, battery light on, 11.5v on scangauge looks like the alternator may have packed up, I was checking the fuel pressure 3.6 bar at idle, notices a slight drop when gently revving the engine need to run it properly at high power though.

 

you have a boost referenced fuel system? Standard NA regulator should be 3.8 bar with engine not running/vac tube disconnected from regulator, but about 0.7 lower @ idle.

Pressure + injector settings must be correcty for OBD to run well...

 

 

I am showing 3.4 bar not running

[Exmantaa]

Strange, as the OEM Z22SE pressure is around 3.8 bar... (56 or 58psi) Is your regulator adjustable?

If you run @ lower fuelpressure, the OBD injectortable must be compensated for that!

[NickB787]

OEM unit, will try to borrow one to replace to one I have then try it again

[leevx2.2]

I have a few pressure regulators Nick

Get thee to an airfield!

Great will be in touch in a few days Lee, cheers

Very true with a smooth runway

blasting round heathrow perimeter road, till the airport police imposed a speed limit.

 

[NickB787]

now where were we. New alternator coming tomorrow, PFR being borrowed from Lee, will try to get it running

If you know of a runway or similar we could use,i would love to smooth up my map and share the costs. We could make our own activity day...

[fezzasus]

+ me

[NickB787]

where is there a smooth runway though? 

 

I now have 2 alternators sat here  I ordered the new one then when I went to collect the original one they had already repaired it for me and as it has the 6 rib pulley on looks like thats going back on today, but not till I double check it with the new one to make certain the new one is correct.

I don't want it sat here as a spare if it's wrong.

 

Got a FPR form Lee yesterday so that will go on so I can check if there is any difference in FP between the two.

speak to one of the small airfields, cotswold, fairoaks , explain you want access to run up and down , at most for a duration of a few minutes per run, and say you are happy to move off for ATC.

[NickB787]

Might try Cranfield biggest problem I know will be if they mention the word insurance

runway lights , cars dropping oil / debris , all a pain . Maybe a trip up to Lincoln, some disused runways , reasonable surfaces.

[VIX]

Just some thoughts. Seems you've discounted Brunters so some other possibles. I did an MSE academy day at Upper Heyford years ago, no idea if the airfield track is still available. We did that training day at Alconbury with Ben - although I don't recall it being that smooth. Can Plans get you out at Dunsfold?
