havent got the car back yet so havent picked up any sheets :oops:
had a running update at 18psi ,runnning nicely, with plenty of fuel left to call on, sitting at roundabouts 180kw.

the old dynoed 174kw was only @15psi but on a different dyno , both hub. quite a significant difference between the two tho,and the dyno tis on now is known for showing lower figures.

so hopefully i'll be out to pick it up on monday,with dyno sheets etc and will post them soon after.

my piddly vf24 is nothing compared to your giant truck turbos barry , its working pretty hard :wink:

Yeah its supposed to be at least 10% difference. Speedtechs is hte lower one.

It does seem to be about right when I compare my old plot to the new one too.

Come on 200kw's Jeremy! 8)

franklin cams sell trd 20v ones and they listed them as 1.420"=60 lbs
and the cams trd made for 20v were huge so they would be quite stiff

stock blacktop springs been
33.5-37lb at 1.48"

true, for your boost you prolly need the strongest you can find
im just running cams so they should be fine, pritty sure the TRD ones are stiffer than toda tho

also Iv lost intrest in kelford everytime iv talked to them they throw me a sales pitch... not the facts of what I need or what they can do for me

they had all the lbs figures etc, I think they are at the workshop written down some where, but they werent that good thats why I done away with going for TRD springs, I wanted TRD cos it sounds cool :D but didnt suit my application.

You may find that all the TRD 20V stuff is designed for NA not turbo applications.
