Cheers for a good day Homer - well, the half of it we saw anyway! :D

 

Useful tip for anyone running low on fuel - simply follow me with a bucket and wait for my exhaust to fill it up - my AFR's were below 10:1 above 5000rpm! :eek: Think I'll have to get a boost controller just to use all that excess fuel! :D

Can Really see here how the stock cams choke up with larger turbos, afr go alot richer.

 

Was going to finish tweaking the car on the rollers as up at that rev range on the road this thing is an animal but we were only able to get one run due to the rear tyres catching the wings very badly were the car was strapped down. i can certainly say this car "burns rubber"

 

As some of you may have seen i was really gutted about this car as all the cars i map that went on the dyno i pull 4 degrees of timing on the first run and then increase till the car makes no more power with no det this is when the car is at MBT.

 

So there is alot more to come, I reckon 640@fly easy but with a set of 264 and race fuel well :D

Thanks for organising today - really enjoyed myself, and good to see the old faces and meet some new :)

 

RE: my strange power figure and running a little lean, aside from the obvious (blocked fuel filter/ Walbro a bit tired (only been in a year and a half though)/what else?) is it also possible my turbo's aren't as stock as I thought? Would that account for it?

 

Edit: what's a sensible transmission loss for an auto and based on that calculation what would my flywheel HP have been?

 

Edit 2: would water injection be a good idea? ;)

The manuals were quoted at around 16% and autos are supposed to be worse, so 20% may be reasonable. Therefore divide your figs by 4 and mult by 5, should be in the right ball-park. If you think this is too much, then divide by 5 and mult by 6 for 16.7% loss :)

Thanks Ryan for help and Darryl for advice.

My car will be going to Paul Whiffin, hopefully it will be ok after that.

 

Nice. I want to know what mine would make if it wasn't leaking boost!!!!!!

I think keef pulled the spec list from the car sale site in japan but i would 99% say for sure its not running higher lift cams as the engine chokes up after 6200rpm and i very much doubt that t51 is running out of puff :D

 

The cam gears were standard also if i remember and they said hks cam gears of the spec on site
