Cant wait to see my old one added also

Blitz Boy any date yet for this update mate, Oh kids who would have them....:bandit

[BlitzBoy]

will do should have some free time to update during the week

[John Yorke]

Cant you wait till middle of next week:D

[BlitzBoy]

ohhhhh John boy yes im looking forward to ya beasty on the rollers, 500rwhp here we come , of course I can wait

[TwistedHumour]

Can you add me to the list please

The car made 333rwhp @6500 rpm at WGT today  (393 fwhp) :Thumbs-up

The torque has confused me though - it\'s 317 ft/lb at the fly, and 1103.9 at the wheels :o  All at .9bar.  Didn\'t notice till I got home.  Might have to get Pip to check that for me.

The car was loosing quite a bit of power due to boost spike!  It\'s mapped to be safe, but I\'m loosing upto 50hp in the mid range and a possible 30hp on top   I need to take my turbos off and send them up to Pip so I can have the wastegate enlarged a bit more... apparently my engine builder is too good :Thumbsup!

I\'ll post my sheet when I go into work on Monday.

torque is multiplied by gear ratios in the gearbox and diff, whereas power remains unchanged by the ratio and only suffers from losses in the gearbox and diff

if the pull was done in a 1.1 gear and the diff is a 4.1:1 the torque at the hubs should be around 4.1 times that at the flywheel.

1103/317 = 3.5  suggests to be that it was done in a higher gear or there is something odd about the calculated figure at the flywheel.

[TwistedHumour]

Just checked the sheet and is says that the ratio used was 4.1

[MikeLMR]

duh ... my fault. If you loose power through the box but you don\'t loose the rpm\'s (it only changes it due to the ratios there can\'t be an RPM loss anywhere) so you must also loose torque through the gear sets  3.5 is probably 4.1 multiplied by the same loss apparent with the power between hub and fly.

BlitzBOYYYYYYYYYYYYYYYYYYYYYYYYY..Table?:bandit

Two graphs now attached. :bandit :Thumbsup!

The left one is FWHP and the right is RWHP.

Hi guys can I be added to the table.... The specs on the car are below:

13b Street Ported HKS T04e - built by the master himself JayDee
331rwhp @ 0.9bar



Unfortunately this was the only high boost run during mapping as either the wheel was spinning or clutch was slipping, also the plugs were very tired and gave up on this run.... not the best result but hoping to do a power run sometime this summer with some decent plugs and HKS twin spark

 BB are you going to update the table or not. :Typing  

   Some time in the life time of the Queen would be nice.

will get my last dyno print out of pip it was 540@1.1 bar fly and 464 to rears, i think mine makes it the most powerfull built 13b engine by wgt.. but its now broken lol
